A bit of a rarity occurred Sunday....Susie, Tate and I all flew via
RV to lunch. Tate flew in the back of Chris Pratt's
unbelievably beautiful -8 (his first ride in an 8 - pic right).
We ended up with (8) RVs on the ramp and enjoyed a fun walk to and
from the Hard Eight BBQ.
It's been too long. Susie and I launched early so we could
stop in Mineral Wells for cheaper gas on the way down ($3.79).
Five minutes added to the trip to Stephenville, but saved nearly $10
total (KSEP was $4.33). We called Mineral Wells Unicom ten
miles out asking for fuel and the nice lady said 'shut down next to
the fuel truck'. The truck was running and ready to go when we
taxied up. Had us on our way in about ten minutes. What
It's always nice to catch up with other members of the B.C. Squadron, and
we always end up asking ourselves why we don't do it more often.
Hope you had a nice weekend also.

Attempting to Wrap the Cowl ...sahrens
Well Bruce I took your advice. After finishing
the oil door I was going to wrap the empennage
fairing but I decided to have a go at the upper
cowling. Moving to a much larger peice of vinyl was
a little more difficult than I had imagined. The
backing material that is removed is fairly thick and
does not want to bend. I was hesistant to remove all
the backing for fear the vinyl would stick to
itself. It did anyway and much like duck tape, it
really sticks. There is a happy place in there
somewhere where just enough backing is removed to
allow applying the vinyl and removing too much.
All that said about 1/3 of the way into this I knew
it was going to get pulled off. The material is
relatively strong, it will stretch and it will
shrink. It will also tear, especially when heated or
over stretched. Long story short I had some small
pock marks of damage that I wasn't satisfied leaving
on the aircraft. Once that decision was made I just
made this a learning project working on technique,
how much heat was too much and how to work compound

So I went goofing off today with my uncle, just a
chance to burn some fuel and recalibrate my head. 0.7 on the hobbs
and the sun is going down, time to park it. As soon as the mains
touched down on the 30-foot wide pavement I noticed it pulling
right, within less than a second it was pulling right A LOT and I
knew what was happening. Full left rudder was OK through about 40
knots then left brake and more left brake, to the point I was almost
sliding the left wheel coming down through about 10 knots but kept
it on the runway. It was swervy to say the least, but I kept it on
Pulled the wheelpant, the tube would hold air for about 3 minutes so
we just aired it up and used our Rhino tug to pull it back to the
hangar, took 2 mid-way stops for more air to get it put away.
Datalogs showed it was 14 seconds from wheel contact to full stop,
that would have been a rather impressive short-field landing if I
hadn't been so busy trying to suck the seat cushion up my butt. My
condition inspection was due to start in 2 weeks, I guess this just
moved the start point up a bit.
Be careful out there...
Water Bottle Speed Mod
Review of my panel Thread
are a “few” comments, and of course, your mileage may vary:
1. The USB port on the left is so close to the throttle that there
may be interference with the port or the cables;
2. If there is anything dangling from the ignition key, it may hit
the stick when deflected or be a nuisance on your leg;
3. Things that earn their way onto the stick are those that you use
frequently and need promptly, or need to access when both hands are
busy. Boost pump does not qualify. Also, there’s the concept of
flow, that you move your attention around the cockpit in the same
order as they appear on the checklist to make sure that the switches
are all set. Boost pump on the stick probably wouldn’t fit that
4. Similarly, the only reason for having flaps on the stick is if
you need to dump flaps on the rollout. I’ve thought about doing this
on my RV-8;
5. Nice that your stick grip is not left or right handed;
6. I’ve learned to fly my RV-9A with left hand on the stick, and it
no longer has the awkward feeling it did when I started. You’ll have
all of Phase 1 to get used to it, so you might not need the dual
7. Good that you grouped your switches instead of having a long row;
8. I’d put strobe at the end, rather than in the middle;
9. If you ever do go inside cloud, it will be strobes off, pitot
heat on. You might consider putting them next to each other;
10. The parking brake is in an area normally reserved for power
controls, and more specifically, for carburetor heat. I’d move it.
Similarly for cabin heat;
11. No point in putting warning lights on the center stack, put them
in front of the pilot;
12. Having a light for fuel pump on is no longer considered by all
to be good human factors (quiet, dark cockpit concept). The argument
is that it gets you used to seeing a light on;
13. Move the seat warmer switches closer to the pilot.
Hope this helps,
Well, not only am I nuts for polishing my aircraft, I also am
using vinyl as well. So I started with the easiest component I could
find, the oil door. It took about an hour to explore how much the
vinyl would stretch / shrink..it will also tear.
All in all it was fairly easy to work with once I got started.
And more wrapping ...
I did use the end roll piece approach to vinyl
wrapping and had my kids cut them before applying

Split Screen or 2 Portrait displays
(Des) As a new builder, panel
questions are coming up, and I wonder if there are any comments or
suggestions about which setup would have better utility.
The 10" model allows a split screen, so I wonder if anyone is
finding advantages of using two of the 7" Portrait displays? (well,
one could serve as a backup). Looks like you lose a control knob on
the 7" model. And I haven't seen any examples of the 7" screen
allowing a full screen view of traffic, weather or engine
None of the "Show us your panel" images in the forum showed the two
Portrait displays side by side (also not shown in the photo
galleries of Steinair or Aerotronics).
The mission is for long cross countries, not yet IFR ticketed.
I'm a big fan of the portrait displays, probably because thats what
I've flown in my own aircraft for a number of years now. The 7" is
taller than the 10" but the 2 7's don't have quite as much screen
area as the 10". I chose to keep my seperate engine monitor (MVP-50)
so that I don't lose the screen real estate to the eng instruments.
Doing it this way gives me a larger/taller map than I would have on
the 10" display. I also prefer to have both screens in front of me
for redundancy purposes, with the flip of a switch or on screen
button push the MFD is immediate a PFD so it's a total non event if
one of the screens fails with this arrangement. I'll post some
update panel pictures showing the 470 touch screens I now have and a
few other changes I've made (added a 660 which I mainly use as a
full time traffic page or IFR plate). I'm considering (if I ever
have time) to change this to a 3 screen setup but honestly I'm VERY
happy with the current layout.

Alternator failure ...make sure you read the last paragraph
So there I was 30 miles to go navigating through
the rain and wind trying to get home, then a battery warning light
comes on, O **** I knew instantly I had to take action and start
load shedding electricity to keep the computer alive to fire the
sparkplugs to keep the engine running, as the battery is on a
limited life and draining quick, if the battery dies, the engine
dies! I needed to decide what goes off NOW, all lights off, It was
getting dark and could barley see, all fans and heat OFF, windscreen
started fogging up and it was getting cold, then the engine rpm
started fluctuating unexpectedly, WHAT THE!, more warning lights
started coming on the panel and then the most scary, the engine
started to miss and started shaking bad, then no power, them more
power and stumbling, very worried I was not going to make it home,
it then started slowing down and I got real scared! then I touched
on the brakes and those lights brought the computer operational
voltage below operational threshold and the engine Died! I
used the very last amount of velocity to make the final
turn.............into the driveway.
WHEW! yes this was in my car tonight, but it was good practice for
my all electric Fuel and IGN powered RV! my goodness I hope I never
have to experience this in the air.

RE: Thermal Expansion and Canopies ...Chris Pratt RV-8
Hopefully this is not too far off topic, but 5 or
6 years ago, after hearing of a rash of cracked
canopies that occurred in cold weather with the
aircraft parked in the hangar, I decided that when
my RV-8 is parked I would not completely close
the canopy, i.e. I do not latch the canopy when
parked in the hangar.
I figure there's no need to put stress on the canopy
when it is just sitting especially with the rapid
changes in temperature we can experience in Texas.
Perhaps it has helped, I have no way of knowing for
sure, but so far no cracks. If you currently are
latching your canopy when securely parked in a
hangar, consider leaving the canopy just slightly
open. It may make a difference.

below 350, oil temp butterfly worked great to adjust
oil temp to 200. Fast and heavy on the controls at

Landings need some work though, takeoff was sweet.

Got to the hangar today and refined the towbar so
it will be more suitable for pushing the RV-6. I
removed the carabiner and fabricated a pin hitch:
It is just two steel straps bolted to the
Cessna-type towbar handle. This should work while
pushing or pulling and is what I would use if I had
a nose-dragger. The drawbar is fabricated from steel
angle and bolts to the brackets that used to attach
the front of the mower deck.

Page 06-02 step 6 ...RV-14
I ordered my RV-14 empennage kit
so now it's time to start asking really, really
basic questions. On the very first page of the build
instructions, it says to "dimple the rivet holes on
the aft face of the VS-702 Front Spar and VS-01401
Front Spar Doubler" and then in the associated
Figure 4 it says "dimple flush aft." Does this mean
to dimple toward the aft or dimple toward the front
so the flush side is to the aft? I assume the
latter, but I don't want to act on a bad assumption
on the very first page of the kit.
I look forward to getting started on the build. Rest
assured that I will have more basic questions as I
go, and for posterity I will make future builders
even more comfortable asking their basic questions
since they can't possibly be more basic than mine

AeroSun VX install attempt #1
Today I removed the right wingtip and read the
installation instructions for the AeroSun VX landing lights. I
thought I understood them pretty well and started to make the cutout
for the light. I placed the template in the tip and drilled both
holes to #30, marked out the area for removal with a fine sharpie
and used a cutoff wheel to remove a large portion. Then I used a
small bit in a air grinder and cut up to the line being sure not to
remove it. Some 100 grit sand paper was used and I sanded into the
line a little before checking the final fit. It took about 3-4 times
of removing just a little here and there before the light would fit
in the cutout like it says in the instructions. I think they call
out about 1/2" on the inside and 2" on the outside that the light
protrudes from the opening. The instructions don't say anything
about trimming the light but I had to remove a little material at
the flanges that hold the insert nuts so they not hit the tip. (pics
below) All looked great and I went ahead and drilled the two screw
holes to #27. I assembled the screws and washers and springs.... Uh
Oh.... something isn't quite right. It looks like by inserting the
screws that the whole light has moved outward by almost 1/8". What
used to fit perfectly now fits like ****. I checked the template
against the left side light and the holes in the template seem to
line up pretty well. Not sure whats going on but I suspect that I
may have to fill the holes and drill new ones. I'll figure this out
tomorrow but I do want to say that I am looking for perfection here.
I like working with fiberglass and I want a perfect even reveal all
around the light of about 1/16". Heres some random pics of the
process and some of me just taking pics at different angles trying
to figure out what to do.
Well that didn't go as planned...opening pandora's box.
So I pulled everything down to

Aircraft Tug-or how to salvage an old Murray ...Sam Buchanan
Even though the paved ramp outside my hangar is
nearly level, the RV-6 just seems to be getting more
difficult each year to pull into the hangar.....the
plane must be getting heavier.....
In order to avoid straining high-mileage body parts
I decided to replace the soft tissue tug with
something more substantial. There was a thread on
VAF some time back about how to repurpose various
means of locomotion so they would move an aircraft
into a hangar.
The father of one our VAFers has a yard-full of lawn
mowers that is in a constant state of flux as he
buys, trades, swaps with the community. He loaded an
old, ugly derelict Murray riding mower of 1993
vintage on my truck and I proceeded to resurrect it
as an RV tug. After some minor refreshening of the
engine, tubes in the dry-rotted tires and a complete
tear-down for cleaning and paint after throwing away
everything that didn't look like a tug, I have a rig
that effortlessly pulls the RV-6 up the ramp and
into the hangar. My regular towbar attaches to a
drawbar on the front of the tug and it backs the
RV-6 into place. My back and knees will live to fly

I ended up with the G5 and Backup Battery. My
panel is mainly Dynon so I wanted a backup from a
different manufacturer. The G5 has a serial
connection to the GTN650. The Mini would have been
my first choice but it didn't fit in the space I had
after removing the Dynon D6. The Mini is 4.35" wide,
the G5 is 3.42"
I have been very happy with the G5. Garmin did a

for sure I'd need to use an external antenna but the
internal one works great, even at the top of the

A case of tall pilot/short pilot
The lady and I both have separate
partnerships in certified aircraft but are thinking
of selling off and getting our first plane together,
an RV-6. Thankfully, we live in an RV rich area with
an active EAA chapter. We were able to do a fit
check in a local RV-6 to gather more information on
whether this platform will work for us. We came away
with a few A-HA items.
1. I am 6’3. She is 5’4. The a/c we sat in had about
3” of fwd adjustment on the seat to get her closer
but even full forward, she would need the pedals
closer to her feet. We could put an extension on the
pedal, but we’d also be swapping seats regularly.
Anyone dealt with an issue like this? A back cushion
might help but then we would need to ensure the
ability for full aft stick deflection. Perhaps not a
major issue since she is small.
I was told the placement of pedals are one of the
design decisions made by the builder and can vary
between airframes. The builder of this test bird was
tall like me so perhaps this example was ideal for

The highlights of the break were time with her, of course, but also
watching her learn to drive the zero turn mower in the driveway, and
flying the drone. Took her for an hour RV flight and got a
couple of waves from her in the driveway as I flew over once or

A Steer, A Tandem Bike, Mountain Bikes: What have you hauled in your
I saw another thread recently that
talked about how great a bearhawk is at hauling
things. I don't think many people realize how much
you can get in an RV-10. It's got the largest, most
comfortable rear seats of any piston single I've
been in. That includes a several aircraft noted for
their interior volume including a C-182, Trinidad,
and Piper Lance. The Lance of course had more total
volume, you just had to choose between legroom or
shoulder room as a passenger.
Ultimately, the 10 is so useful, so fast, and still
so much fun to fly I barely miss the 8. Yes, I do
miss aerobatics, and the 8 is a much better
formation platform. That said the 10 is surprisingly
capable of formation at least up to the FFI limits.
I'll start: I've hauled my family of 4 and a week's
camping gear including a huge tent to Oshkosh. I've
carried the (frozen and edible parts) of what was
once a 1200lb steer, our new tandem bike, and two

J_Turner Status Report ...RV-7
Today I wanted to get the wingtips in place and
drilled to the wings. I only got the right one
drilled to #40 but it is straight! To start I made
an aileron center jig and clamped the aileron to it.
Then I had to cut some material off the bellcrank
jig to allow it to clear the Garmin AP servo brace.
Once those were in place I adjusted the pushrod
length and tightened it down. Next I clamped the
bell crank jig to the bolt that holds the pushrod so
I could get the wingtip aligned.

300 Hours: Then and now ...Bob Collins
I hit 299.6 hours this morning in
the RV-12iS project. It's been almost a year to the
day since I took delivery of the first kit. In the
first year, there was a lot of waiting around. I
didn't realize how quickly the emp kit went together
so I had 12 weeks to cool my jets before the wings
arrived. I knocked those off in six weeks but by
then the 12iS has been announced so I chose to delay
delivery of the fuselage kit to get the redesign.
I'm continually amazed by how quickly this has gone
together, even with the stuck-in-traffic pace.
I looked up my RV-7A build and was surprised to see
that 300 hours if about a year's work on that
project too. That makes sense. My routine is roughly
the same: About 1-1.5 hours of work after work, and
a few hours each weekend day.

Today was fun, I match drilled approx. 302 holes
in the right lower wing skin. Deburred about 1100
holes, dimpled around 500 holes and set about 30
rivets. I think I'd rather be doing fiberglass work
but hopefully tomorrow I can finish the skin and
start on fitting the wingtips. Oh yeah, I also made
one extra hole while dimpling. I didn't get too

RE: Mountain Bikes in RV-14 Cargo Area ...Jared RV-14A
The RV-14's baggage space is large. With that
being said I believe the challenge may be getting
the bike's frame between the seat back cross-member
and the roll bar. You'd probably have to turn the
frame on it side to pass through and then rotate it
back to right side up. Not sure if you'd have to
remove the fork as well. I doubt you'd be able to
get a second bike back there, due to the
manipulation required as described above. Possibly
if you remove the fork/handle bars. Probably one of
those things you'd have to try. Like others have
eluded too, if you plan to transport a mountain bike

Working on Wiring
Back to Basics | January/February 2018
January 3, 2018 0001Z. Issue
So Tuesday morning only one aviator on the field was
enough willing to go up for a flight in the 23*F morning
air via RV-6, and that idiot person was me (note
one hangar door open).
I know, I know…I’m a wuss from TX and people up north take saunas in 23*F
I should have worn long underwear (and where is mine?), I need to stuff
some foam into the NACA ducts to keep the leaking air around the
closed vents from bleeding in, and heated motorcycle gloves that
plug into 12V are seeming more and more attractive. Other than the
14 minutes it took to get my oil to 100*F, it was a pretty nice
flight. The wing sure liked that dense air. Hadn't flown in
five days...felt good to get off the surface for some alumitherapy
slash mental re-calibration.
And I need to tape off some of my oil cooler. We really just don’t get
that much insanely cold air down here.
It's forecast to be above freezing today for the first time in 80 hours,
so we're pumped. That
fountain ice near the airport is gonna melt.
New Years Flights
Very cold here, +9F this morning
and got up to +17F in the afternoon but had good
sunshine and basically no wind. I couldn't stand it
and had to go flying, went goofing off with a buddy
and shot some touch and goes, just burning fuel.
Interestingly, we have quite the strong temperature
inversion parked over west Texas right now, at 5000'
it was 12F outside and at 8000' it was 41F.
Altimeter was the highest I've seen it, at 30.56
this afternoon, by setting to my known private home

Regarding Buldged Control Surfaces
For anyone else interested, there is potential
for this to have a negative impact on handle if it
exists on other control surfaces as well....
A bulged control surface will make it act as if it
were narrower in cord. That will reduce the
aerodynamic feedback... I.E. make the control forces
lighter (possibly to a degree that impacts control
It can also impact static stability. If the
aerodynamic feedback force of the control circuit is
lower than desirable, it has a lower working force
against any friction within the system.
A small bit of turbulence or an occupant bumping the
stick might induce a small movement of the system
that doesn't return to the same position each time
because the system feedback is too low to overcome
the system friction.
BTW, this is also why friction in the pitch circuit
is such a bad thing. Even if the elevators have the
proper shape they won't re-center the same each time
they are displaced if the friction is too high.
A mis-shaped rudder can also have a negative effect
by reducing centering tenancy (once again hinging
friction being a bad thing) and making the airplane
appear to have reduced yaw stability.
Maintenance Tracking Board

hijacked), I was asked by Plummit about my

I'm excited to announce, I have finally decided
to build an RV-10. Ordered a kit and built a EAA
Work Table (modified to my needs). Tail-kit should
be arriving tomorrow (DFW).
I started with a RV-7 and later decide to buy a
RV-6. I have flow a bit more than a couple of
hundred hours in an RV-6 now and I feel a RV-10 fits
my needs better. One of the main reasons for me to
decide to build an RV-10 is the VAF Community. Big
Thanks to Gary Sobek who helped me fly the RV-6 from
San Diego to NJ. I learnt so much from him on that
trip, great guy, I can't thank him enough. All I had
was 60 Hours of Cessna 172 and 10hours of RV-6

jump. Flying along with Vlad for a while, a couple
of years ago has helped me immensely to change from
a Mission Based Mindset(Flight school) to a Fun
I assessed my situation and the biggest roadblock I
have is time. I travel for work Sunday Night -
Thursday (Currently to Montreal). I also have a
couple more hobbies other than flying(Motorcycle
Track Days, Rock Climbing, etc) so it is going to be
challenging. Since I'm already flying, this project
is not critical, albeit very significant. It will be
an interesting journey working on it and finishing

but still working on it!!

Need More Heat!
Happy New Year Everyone,
Flew the RV6A today in this 16 degree weather. To
call the heat system inadequate is an
understatement. I have a Vetterman exhaust with one
heat muff, no mufflers, coming into the cabin in the
toe area. Is there anything I can go to get some
more heat into the cabin? I'm thinking add another
muff to the other side and wrap them with an exhaust
heat wrap. What is everyone else in cold climates
using for cabin heat?
RV inverted spin no fear
Having done hundreds of inverted
spins in my RV4 since it's in my free style for
competition for the last three years, I can offer
some advice. It takes specific inputs, attitude, and
timing to make an RV spin inverted as other RV
competitors will concur. I received advanced
instruction in an Extra 300 before I tried it.
Here's a video of a botched hammerhead that starts a
tail slide and possible inverted spin at the 1
minute point, but it never gets to the rotation
The error with this hammer head
was dragging the right wing, kicking left rudder too
late which wasn't effective in rotating the nose
Be careful and hope to see y'all in the box this

Canopy fairing fiberglass
Can I do the fuel tanks again?
Fiberglass sanding is tough work! When is says don’t
worry if the glass overlaps the forward edge the
work needed to sand it away isn’t mentioned.
The front center is looking pretty good.
On the left side I attached a pic. Getting the
overlap off on the front sacrificed some of piece A.
There is also metal showing on the aft edge. You
can’t see it but there is a bit of a swale
depression between the two.
I was going to lay in another piece of glass cut to
size to cover this metal and lay it over some small
strips in the depression.
On the other side that little corner where the
window meets the aft structure looks a lot better
but a little bit of the tip of the metal at that
corner shows. How critical is that? Should I keep
glassing it until I get a edge of glass to the top
of the metal? Or will the final epoxy and primer
cure my worry?
Getting ready to order some wings! (slow build) ...SeanM RV-10
I just about have the RV10 emp kit
finished up. I'm just waiting on some composite
materials to arrive. In the meantime my mind has now
turned to the wings. I need to get things in order
before I place my order.
Vans Wing kit options-
1. Landing lights- I will probably go with the
sunspot LED landing light kit that vans supplies
2. Aileron trim- Will be doing this. "operates
independently from autopilot". If I want an AP
system does this mean I'll need different servos for
that too? At what point do I need to start thinking
about an AP system?
3. Float fuel sending units- Will be going this
Things I'm starting to look into:
1. Wing and tail position/strobes.
2. Pitot (will probably upgrade to something heated)
3. Stall horn (is this included in the wing kit?)
5. Would like to do a Garmin IFR type setup /w AP,
but I need to research this more. should I be
looking into this now as well?
When is the right time to get some wiring/crimping
tools? Now? Or are they not needed until mid-way
through the wings? (I'll probably splurge on the
steinair master kit).
Is that a good list? Is there anything else that I
should be researching right now?

My landing gear needs some suggestions, quick!
A few weeks ago my left tire went flat on rollout.
I bought new tires and tubes which I installed today. My gear has
been shaky and I thought the new rubber may help. I previously
reviewed the wheel/axel alignment and it looked ok.
Today after the tires were installed I started to check things and
found I could move the left gear by hand back and forth a few
degrees. I looked up and saw the gear/engine mount bolt moving. I
removed the bolt and found this. (yes, JB Weld was involved)

Hangar Lighting - The importance of Color Rendering
Hangar Lighting is a common topic discussed
here and a very important one for anyone building an airplane
indoors. There are many factors that go into a quality
lighting design but one often overlooked is Color Rendering. CRI,
Color Rendering Index, is a number from 0-100, 100 being the most
true representation of all colors as viewed with the human eye.
Traditional older lighting sources still commonly found in our
hangars are T12 Fluorescent and Metal Halide. Both of these sources
have very poor Color Rendering, usually 60 CRI or worse. Other newer
sources like T5 or T8 Fluorescent, or LED typically will have better
Here is an example. The top pic is 400W MH, the bottom LED. The MH I
would estimate at 60 CRI or lower as they degrade with age, the LED
is 70 CRI.

Oh boy, I have some CNC controls to bring into the
current decade. Life is good.
What is it? It is a fixed gantry, 4'x4' CNC router,
with three 5hp spindles, made by a company called
Standard Router Inc. that went out of business in
2005. It is all very heavy steel (can you say RIGID)
with a solid 1.5" thick aluminum table setup for
vacuum hold down. After having moved it, I'm
guessing it weighs over 4000#. I have powered it up
in the shop but am already in the process of tearing
down the controls for a major update.
Tail wheel takeoff technique for bumps
I had an unpleasant takeoff from Catalina island.
I am a tail wheel noob and my normal takeoff
technique is to fly the tail early so I can see.
While on the roll at Catalina near rotate speed, I
hit a hump in the runway which launched me in the
air. I got the nose down and accelerated and
continued flying but it was not pleasant (and it was
my Wife’s first trip in the plane).
I am pretty sure that when the wheels hit the hump,
the inertia of the tail kept it where it was with
the nose rising, increasing the AOA inducing a
premature lift off. The question is, what is the
best technique to prevent that.

Physics of Air Pressure in the RV-14 ...Scott
The physics of air pressure is such that just
like water, it will flow primarily to the path of
Pressure Delta (difference) is what makes air flow
from one point to another.
If there is no Delta, there is no movement.
If the RV-14 heat system has both heat valves
unblocked there is one pressure source (the heat
muff circuit) feeding four paths for the air flow
(two waste/spill-off paths and two into the cockpit
Regardless of where you want the heated air to go
(how you set the heat control valves), it will flow
to the path of least resistance. I.E., if the pilot
is trying to get heat on only their side and there
is no block-off installed on the co-pilot side
valve, the flow can choose to go that way and out
through the waste flow path instead.
As designed, there is still a small amount of
interaction between the left and right heater
controls, but it is not a problem..... as long as
they are only sharing one waste flow path.
This is just one of many little design details that
RV-14 builders are benefiting from with the advanced
level of the kit.... and not having to experiment
with and resolve on their own once flying.

My experience running a tank dry
Due to my impatience and
boneheaded fuel expectations I managed to run a tank
dry on a recent long cross country.
I knew the left tank was getting close to being
empty but I thought it would get me another 10-15
minutes along before I switched to the right tank. I
was about 20 minutes from home with rapidly
diminishing daylight at 3500 ft. "The fuel in the
right tank would be enough to get me home with
reserves", was my thinking before the left tank went
I did not think it would happen but suddenly the
engine quit with the prop windmilling at a good
clip. I was pretty quick to switch tanks and after
about 3 long seconds the engine restarted. I don't
remember if I pushed in the mixture and turned on
the boost pump but was very relieved that the power
came back on.
So...do I fly on, confident that the right tank
would carry me through a darkening sky to my
destination? No. I finally made a wise decision and
diverted 9 miles to an airport I knew had SS fuel. I
made it home later than I planned and logged some
night flying and a landing. I would have gotten home
sooner if I had just topped off the tanks before I
left in the first place.
Lesson Learned: After 11 years and 1100 hrs with my
RV9, overconfidence, impatience, and complacency are
real dangers. I'm glad this happened. It needed to
happen and I am a better pilot for it.

December is the Month to Help Keep VAF Online
December once again, so it’s time for me to
beg grovel respectfully ask those folks who haven’t yet sent in
their 2017 donation to please send it in now so I can pay the bills I
need to pay to stay in business and do the food, shelter and clothing
thing. If you haven’t heard this year-end speech before, VAF is my
full time job, my sole source of income for our family (right), and the
donations usually determine if we end the year in the black or not.
If you have already donated in 2017, THANK YOU! I’m trying my hardest to
provide the RV community with a quality product that motivates,
educates and entertains. I want to keep doing it, but I don't get to make that
call. You do.
HERE for all the
‘how to donate’ details, and thank you again to those who help me keep
the lights on.
As for the rest of the fam in '17, Susie is still providing free yoga
classes to cancer patients (link),
Audrey is currently in her 2nd rotation in year one (research) on her
path to getting her PhD in Chemical Biology, and Tate is rocking it as a
junior in high school - excelling in English, Art and Physics while
refining those incredibly important interpersonal skills at the
front counter of Freddy's Frozen Custard & Steakburgers.
My wife and children never cease to inspire, amaze and humble me with
their dedication, compassion and altruism. My clumsy efforts to
continually bring VAF to the RV community is an attempt at bringing a
few smiles to some faces in an increasingly caustic world. My wife
and kids set the bar high, and motivate me.

Been Working in the Wing ;^) ...J_Turner
Been slow on the build the last couple of days
but, I did make some progress today. If anyone
remembers a few days ago I got the lights in the
left wing wired up and tested. Everything was quiet
as a mouse in the headset. The problem with that
test was that I didn't have the antennas connected.
When cleaning my bench for prepping the wing skin, I
decided to go ahead and connect them to the plane
just to get them out of the way. At the end of the
day last Saturday, I wanted to demonstrate how nice
and quiet it was to my brother. Powered everything
on and had all kind of radio noise when I turned on
any light. The lights were breaking squelch on both
radios (GTN 750 and GTR 20). After messing with it
for a few minutes I just said the heck with it and
went home to think about the problem. I read about
the auto squelch function and wondered if that was
the problem since There have been updates to address
this function. My G3X's have never been updated
since I got them in early '15. Today I downloaded
the latest software from the Garmin site and
proceeded to do the update. Problem 1) The GSU 73
wouldn't update and problem 2) the GTR 20 wouldn't
update. Called Garmin's tech support and got quickly
transferred to a guy that helped me get the GSU 73
to update. Rebooted in config mode and it updated
very quickly. I think I wasn't giving it enough time
to do its thing. Problem 2 took longer, I called
back and we couldn't quite figure out what was
happening, I said I'll just wait and call back after
giving it some more time. More time was not what it
needed. It seems I may have a CAN bus problem. After
calling back, he told me to turn everything off
except the PFD and the GTR 20. It worked. I have
some troubleshooting to do. The good thing is that
my GTR 20 radio is dead quiet now with all of the
lights on just need to figure out why I'm getting
some error on the CAN bus.
I did manage to get the aileron servo bolted in and
set a few more rivets in the left wing. Man its hard

Autopilot During IFR Checkride ...Scott Stewart
The question of "how much autopilot to use during
the checkride?" was something that I discussed with
all three of my CFIIs.
The first guy, who is very "old school", said that I
may be asked to demonstrate it, but not to expect to
get to use it for anything other than a basic
demonstration during the checkride. The second guy,
who is also "old school" said that I could expect to
use it when things got real busy in the cockpit, for
example to keep wings level while copying
clearances. The third guy said to go ahead and use
it in all phases of flight, and explain to the DPE
when and why I'm using it. I went with the third
I used the autopilot during about 80% of
cruise/level flight, but turned it off occasionally
just to show I could keep the plane level
wings/level altitude without the autopilot. I also
used the autopilot as ATC was giving me radar
vectors to the approach. I made sure to disengage
the autopilot before crossing the FAF, although I
did re-engage it after the FAF on two of the
Finally, on the final approach to KRNT, which was a
RNAV/GPS approach, the DPE failed my primary EFIS.
When he did that, I engaged the autopilot and let it
fly the approach while I reconfigured the
secondary/passenger EFIS to show the approach plate.
All told, I probably used the autopilot for about
50% of my checkride.

Whenever undertaking a maintenance issue be sure
and check the simple things first. By way of example
I will talk about a fuel leak on one of my aircraft.
Now this leak was on my Citabria on floats but since
I also have an RV8 I believe the issue is still
valid. One day when heading out to go flying I
noticed a drip, drip drip...of fuel come from the
back on the cowling. Immediately turned the fuel
selector to the off position and went to work on the
cowling. Removed cowl, only dropping a couple tools
in the water. Started checking all the fuel
connections and could find nothing loose. Turned the

IFR training in an RV-7? I did it! ...Scott Stewart RV-7
completed my RV-7 in 2009 and have over 1100 hours
on it to date. Living in the Seattle area, there are
a lot of weather issues to deal with. In the past
few years, there have been a few times that I’ve had
to cancel planned trips due to weather. I’ve also
had to turn back from coming over the Cascades due
to getting stuck VFR on top of the clouds. It’s
never fun at the end of a trip to come home and
spend the last hour of the flight looking for a hole
in the clouds to circle down through. It’s not very
So last year I decided it was time to move forward
on my Instrument ticket. My goal was to use my own
plane to train in, so the first hurdle was to put in
an instrument panel that would be legal, and would
be easy to fly on instruments. I wasn’t interested
in the basic six-pack with vacuum gauges and a VOR.
No! I wanted to have something that I would be
is a great place to look at the latest and greatest.
I spent an entire week with one thought running
through my head – IFR Instrument Panel! By the end
of the week, I had decided on my setup and began
planning the new panel. The legacy Dynon EFIS and
EMS would go away. The Garmin transponder and comm
radio are out also.
My new panel has Dynon Skyview 10” Touch and Dynon
Skyview 7” EFIS, Avidyne IFD440 Nav/Com/GPS, PS
Engineering audio panel, Dynon Comm, Dynon (Trig)
Transponder, Dynon autopilot, and meets the 2020
ADSB requirements. I cut the new panel and had a
friend do the graphics and silkscreen work for me.
The old equipment was removed, and new equipment
I spent a few months testing the new equipment,
learning how to use the Avidyne, and looking for any
bugs. I found a couple of minor issues that were
easy to clear up. The worst issue though, was the
Nav radio (IFD 440 Nav). Although the glideslope on
an ILS approach was rock steady, the localizer
needle was very erratic. It took a lot of
troubleshooting to figure this one out, but I
finally narrowed it down to one of the BNC ends on a
short coax from the Nav/GS splitter to the Avidyne
radio. And sure enough, when I examined the BNC
ends, I found one pin had not been fully inserted in
the assembly. Here’s a video of what the localizer
looked like with the bad BNC pin, and a picture of
the bad BNC pin next to a good BNC connector.
With everything working correctly, it was time to
begin IFR training. I wasn’t interested in going to
one of the local schools, renting a G1000 Cessna
172, and spending thousands of dollars to learn a
system that I would never use again. I wanted to
train in my RV-7, so I had to find an instructor who
would be willing to fly with me. Seattle has a great
flying community, and I was able to find several
CFIIs who could do the job. After flying with
several CFIIs, I settled down to three instructors
who would team-teach me.
I was concerned about the ability of the RV-7 as an
Instrument platform. Would it be too twitchy? Too
nimble? There’s a reason why so many people get
their Instrument ticket in a Cessna. It’s just a
good, stable, reliable airplane. I have done a lot
of aerobatics, formation flight, cross country, and
sight-seeing in my RV-7. Now it was time to see if
it could survive in the Instrument training world.
We began training with standard maneuvers – except
the standard maneuvers were done with my foggles on!
And the RV-7 behaved… OK. Not perfect, but not bad!
I had to learn to have a very smooth, light touch on
the stick, and really focus on the gauges. It took a
few hours of maneuvers to get my skills up to par.
Holding altitude, heading, and speed isn’t easy at
first, but eventually I figured it out.
Approaches, holds, and course intercepts turned out
to be extremely easy with the equipment I had
installed. One of my instructors said that flying
with my panel felt like cheating, because the
instrument scan all happens on one instrument, the
auto-pilot can fly straight and level (or a heading
and altitude) while I was trying to plan the next
maneuver. We moved onto the Cross-country flight
relatively quickly, with a flight from Renton (KRNT)
to Hillsboro (KHIO) to Astoria (KAST) to Hoquiem (KHQM)
to Renton (KRNT). Along the way, we did an ILS
approach to full stop, a Localizer to full stop, a
VOR to the missed approach, and an RNAV-GPS/circle
to land. The cross-country was done in about 75% IMC
conditions, and my RV-7 performed wonderfully!
Fast forward a few months, I had racked up a
whopping 41.0 hrs of actual/simulated IMC, and it
was time to take my checkride. Once again, I had to
find a DPE who would be willing to do an Instrument
checkride in an RV-7. Sure enough, I found my
victim. I briefed him on my equipment, the
experimental RV-7, the tailwheel, the panel, etc.
Oddly enough, he still agreed to go along for the
ride! Because of the experimental nature of the
plane, as well as the engine, as well as the panel,
I had to be prepared to answer all questions about
airworthiness! We spent about 45 minutes going over
airframe and engine logs, discussing the work and
logbook entries that I could do as the builder, and
then going over ADs and service bulletins for the
plane, engine, propeller, and equipment. Finally, he
declared that my RV-7 may indeed be airworthy, and
we completed the checkride.
In summary, if you feel like you’ve got a good
handle on flying your RV, if you are very
comfortable with the instrumentation on your panel,
and if you don’t want to go back to a Cessna for
your Instrument ticket, there’s really no reason for
you not to use your RV!

Engine Misfire Help ...Michael Burbidge 9A
I just finished my third condition inspection.
Before the inspection my engine was running great.
On the first flight after the inspection I was about
15 minutes into the flight, at full power, climbing
through about 4000 ft. when I got what I can only
describe as a misfire. I continued to climb to 7000
ft. and got 3 more misfires, on the way up. I then
leveled off, pulled back the power and headed back
to the airport. I did not get another misfire.
In the first 15 minutes of the flight I was cruising
at about 2500 ft. and probably 50% power. I did not
experience a misfire during that portion of the
flight nor on takeoff.
I have basic Van's instrumentation, so I do not have
recorded flight or engine data. I also did not have
the presence of mind to do any diagnostics. I was
focused on gaining some altitude and getting back to
Mag checks on the ground were fine.
Startup and idle were normal.
Here's the basics of my engine:
1 P-Mag, 1 slick mag
TSMOH @1150 hours
Here's what I did during the condition inspection
that could potentially be related:
Replaced auto plugs on the p-mag, gapped
Cleaned aviation plugs on the slick mag, gapped
Removed and checked p-mag, retimed.
Retimed slick mag, it was about 1 1/2 degree off (it
was overhauled last condition inspection. I think
some drift is normal.)
Slightly re-routed plug wires
Ohm check on auto plug wires
Replaced intake pipe gaskets. (two were leaking)
Replaced intake pipe hose and hose clamps.
Cleaned air filter
Cleaned gascolator (no debri found)
Removed oil cooler, repaired baffle cracks, replaced
Rerouted bottom oil cooler line to avoid chaffing
Replaced, rerouted breather tube to avoid new oil
cooler line placement
I'm not sure where to start looking for the problem.
So far I have rechecked p-mag and mag timing.
Replaced the new auto plugs with another set. Looked
for signs of intake leaks (blue stains, I'm not sure
how long it would take so show up) Rerouted plug
wires so that the aviation wires do not cross with
the auto wires. (they were touching in one spot) My
auto plug wires are separated as described in the
Having done this, my inclination is to go for
another flight, staying close to the airport and if
the problem persists, I will do a mag check at
altitude, turn on the boost pump at altitude to see
if the problem goes away.
I would appreciate any other diagnostics suggestions
to help me find the problem.

The End (of the Wing) Is Near
The end is near, both of 2017 and this wing
The ailerons are finished, and I am quite happy with
the results. One aileron trailing edge is dead
straight, the second took a little work to get out a
very minor ripple; I think the ripple was caused by
not riveting the trailing edge together as soon as
the pro-seal was dry and letting the trailing edge
sit unclamped for a few days. No worries should be
I think the secret to building ailerons with no
twist is the leading edge straightness. I spent a
little extra time making sure the bottom skin was
absolutely flat from the stainless steel leading
edge weight to the spar. Since drilling the leading
edge is very difficult due to the super hard
stainless steel, I ended up having some extra
"lightening" holes in the stainless steel bar.
During final assembly, I made sure the leading edge
ribs sat flat on my super flat surface plate
(granite kitchen counter top). Once the leading edge
is riveted to the spar, the aileron becomes
enormously stiff. I am glad I took the extra time to
make this part perfect.

Pitot install critique please!
Hello all, wanted to get opinions
if my Dynon heated pitot install looks good before I
carry on. I wanted to get this done before riveting
the outer lower skins. Wiring isn't done yet but
that's just a matter of installing a connector on
the 3 power wires. I was going to use a molex
connector for that but I don't have one. I do have
molex pins though. Is it OK to use the pins without
the plastic connector part and use heat shrink tube
over each wire to hold the pins and wires together?

like I'm going to take that connection apart

The Flat That Wasn't

Before all the recent storms and
fog here I took Flash up for some quality
time in the Tropo. After landing I taxied back
up to the hangar, mental gyros all recalibrated, and
felt what I was absolutely certain was my right tire
going flat FAST. Flop. Flop.
Roll. Bump. Clang. Flop.
Uncommanded right turn. Flop. Wheel pant
obviously being destroyed. Mixture cutoff and
on the brakes to ponder my next move.
I sat there in the cockpit for a
minute or so turning off switches, unlatching
harnesses and re-stowing the headset, starting to
mentally plan the next two hours of wheel pant
removal, finding a tube, breaking the seal and all
the other fun of tire love (a.k.a. Crap Sandwich).
I got out and walked around to view the carnage...
There was none.
the offending rat bastard
The reflector on the taxiway in
front of my hangar had broken from its glue on the
concrete on my taxi out, and when I returned
Flash's right main slid it roughly 15' in fits
and starts. Hopping a little, sliding a
little, making grinding noises - grinding down that
reflector like nobody's business. Noises and
vibrations translating through the airframe and into
my headset cups doing the best 'I have a flat'
imitation I've heard or felt.
Take away lesson: Before you
sit in the plane planning your morning's damage
repair....maybe get out first and see if you're

Trial fitting the HS 1213 hinge brackets to the F1211 bearings and
they are to tight ...Jeff Wright RV-12
Hi all, I'm at the point where I'm trial fitting
the HS 1213 hinge brackets to the F1211 bearings and
they are to tight. They fit when there are no
washers included but too tight when there are
washers installed. I'm at a loss about what to do
The brackets are square and the stops are not
undersized. Everything seems good according to the
plans but the fit is just a smidge to tight. I'm
guessing that installing the stabilator after the
emp cone is done would be a real pain if this fit is
not "slide right in" tight.
Can I? Yep.
In flight Rotax power loss
First this is kind of long. Background: Rotax 912
ULS over 200 hours. A few hours after annual. On
annual new plugs and the floats replaced on left
carb. One float was heavy. Carbs were balanced
before I found out float was heavy so they now
appear to be a little off balance. Prop pitched a
little coarser than before, testing the denser
winter air with static around 5000 on ground and
about 5100 in climb out. Flown about 5 hours in the
latest configuration. Climb solo at around 1400 fpm
After take off climbed to 3000' and ran a few
minutes at 5500 rpm at 124 KTS TAS. Slowed to 5350
for cruise and shortly after stabilized rpm suddenly
dropped to 4700 and felt a little rough. Full
throttle application caused no power increase.
Reducing power the engine was much rougher. I turned
around and limped along back home until the Dynon
showed well within glide distance. I then stopped
the prop and requested traffic clearance for a dead
stick landing. In retrospect I should have kept the
engine at WOT since it was relatively smooth there
and not reduced power and shut it off until in the
pattern but I was afraid whatever was wrong would be
made worse. With prop stopped and holding 60 knots
until touch down I averaged 600 fpm descent rate. I
now know stopped engine glide performance.
On ground the engine started fine with normal engine
run up. Powering up the engine felt starved and
would not go over 4600 rpm and would shutter and run
rougher the more throttle you added to increase rpm.
Pulled plugs and if anything they looked lean with
slight light gray deposits. Compression felt fine
but I will run a compression check. Gasolator clear,
everything in the green and as before except the in
flight EGT difference.
Downloaded Dynon. It showed all in line up to about
1/2 way in my 5500 rpm run when the right and left
EGT deviated from 712 and 700 to 726 and 793. That
spread continued until I shut down the engine.
Before I lost power fuel flow was 5.1 gph and it
then deviated from 4.4 to 5.1.
I'm thinking a fuel line obstruction after the
totalizer but before carbs so after the compression
check I'll start disconnecting lines and checking
fuel flow. Other idea is an ignition breakdown at
rpm or under load. Hopefully nothing internal.
Before I start another s... storm on 5100 rpm in
climb as I see being heavily discussed, that is at
75 kts climb which is only maintained for a short
time. Cruise climb is well over 5200 rpm with rate
of climb decreasing accordingly. Yes I'm pitched
currently as a trial to exceed 120 kts but not at
sea level or full gross weight but 3000' solo. It
will even gain another knot or two when you run it
up to red line.

Heat Muff Tip
Two things I have learned for better heat muff
1) You want the opening in the baffle to the SCAT
tube to be no larger that 1" diameter. Use tape or a
restriction plate to close it down. You need to give
the air time in the heat muff to pick up heat. More
air flow than that just means more cold air into the
2) Use coiled solid copper wire inside the heat muff
to improve heat transfer. 18g or 14g solid wire
wound into a tight coil about 1/2" diameter so it
looks like a long spring. I use a pencil or a 1/4
socket extension for a mandrel. Take those coils and
wrap them around the exhaust pipe inside the muff so
the air has to flow between the wire loops on its
way to the outlet.

Revised Electrical System ...please review
Only odd spec is the mounting requirement, a
0.125"x16x16 aluminum plate for the full 200 amp
rating. Surely the heat sink is needed only for
continuous use at high amps? The heat sink
size is the same for all three from 100A through
200A so I would think there is some wiggle room. If
I decided to go with an SSC I only have room to
mount on a .125 sink slightly larger than the
contactor. I'm thinking with typical buss amps there
should not be heat issues.
Excellent points! I have revised my diagram to
reflect your inputs.

whole RV spectrum:
1. Rob working on his -8.
2. Monk working on three different RVs
3. Kay getting ready to go practice acro in his 8A.
4. Three of the other usual suspects briefing for a
formation hop...planes on the ramp waiting.
When I came back into the pattern
Kay was on short final, the formation gaggle was joining
up and cruising out to the NW and I had a text on my

Control linkages and washers ...Chjris Mitchell RV-4 project
Q: I am trying to install the various
control linkages from the sticks back to the
elevator. There seems to be a shortage of
information on the plans, though I might well be
missing something. Not helped by these odd washer
sizes that are called out in various places.
So, F-635 on drawing 38. The center bearing has two
AN960-416 washers and two 5702-95-30 washers. Nice
clear diagram and I understand that the 5702 95 30
washers capture the bearing if it fails. These funny
washers are 0.25id and .75 od. Fair enough?
Drawing 30. Where F-441, the big pushrod, is
attached to the elevator horns, there is an AN3 bolt
and an AN365-1032 nut, plus enough washers between
the elevator horns to fill the gap.
Drawing 28, F399 and F-440, are connected to the
front stick base, the rear stick base and back to
the bottom of the bell crank. Two of those locations
(F-440 to back of rear stick and F-440 to bottom of
bellcrank.) indicate to use the little 5702-75-60
spacers/washers. Should I use the same little
washers on the other two locations (front stick to
F-439 and F-439 to rear stick)? That would use up
all 8 of the supplied 5702-75-60.
What about he top of the bell crank to the F441 big
push rod? Can't find the details for that at all.
Finally, two possibly dopey questions:
Why do we not use the larger washers in all these
locations as there are still rod end bearings that
could, presumably, fail?
Why do we use nyloc nuts in these locations rather
than AN - (non-A) bolts, castle nuts/split pins?
As ever, many thanks.
A: (Scott Hersha)
Here's the way I like to think of it - If I was a
bearing in a rod end, and if I became separated from
the rod end (either by failed bearing race or some
defect), then what would happen next. If the answer
is that the rod end and whatever it is connected to
could fall outside of the safe operating area where
it is supposed to be in - it could then jam the
control - well then you have to have something to
prevent that from happening. On your large elevator
pushrod that is captured in the elevator bellcrank,
you don't need a large diameter washer because if
the rod end bearing fails it is held in the same
relative position because it can't get outside the
jaws of that bellcrank - as long as the bolt doesn't
break. On your aileron inboard bracket where it
connects to your aileron push pull tube rod end, you
will need to have the large diameter washer on the
bearing side of the approximately 1/2" spacer that's
there. Even though the whole collection of spacers,
and washers is inside of the aileron bracket, a
failure of that rod end could allow the now
liberated bearing to slide laterally a half inch or
more, which would possibly jam the control tube in
the aft spar opening. That large diameter washer
prevents that from happening.
As far as those very small (and difficult to
install) 5702-75-60 washers - I think the only place
I've seen those used is in place where a normal size
washer would contact and drag on the part that the
ball is pressed in to - like the outboard aileron
bracket on some models, or on a rod bearing where
the rod pivots a lot. That small diameter washer
gives a space between the ball and the normal washer
or surface, so it can move freely without
A: (Gil) There is another
interesting twist here for owners of very early -4
and -6 kits.
Vans changed the vendor for the rod ends, and if you
have the Heim rod ends that were supplied in the
very early kits they had a different profile at the
end of the ball portion. I looks sort of like the
tiny Vans washer was actually built into the design.
I believe this explains why some early kits did not
need the tiny washers while later kits did.
Nevertheless, the aileron pushrods should not bind
in any position of the stick. If they do, add the

and (1) video I took to sum up the flight.
What started as a 'I really don't know where to go'
flight turned into much more....and a movie

This rug really ties the room together, does it

Oil in weird spot in cabin
Noticed a couple drops of oil underneath the
throttle cable where it meets the throttle lever in
the cabin. In my RV-8, I have the side panel
throttle quadrant mod, but for purposes of this
discussion should be considered identical to a stock
The other end is connected to a Lyc IO360M1B. The
end of the cable is in the vicinity of the low
pressure oil return lines, so I decowled to
investigate. There was a touch of moistness in that
area but nothing more than usual, and certainly
nothing obvious that caught my eye. I tightened the
hose clamps and buttoned everything up.
Any thoughts? Am I missing something? I checked the
other two cables - prop and mixture - and they are
completely dry (none of them are in the vicinity of
any moistness anyway).
Finally, do any of you replace those short runs of
hose from the aluminum return lines to the case?

Last Harvest: RVator Day Jobs ...Denny RV-12 (wing kit)
The harvest is wrapped up. Not just for the year
but for a career. It has been quite a run but for
everything there is a time. I started the 12 project
three years ago and with a lot of seasonal
interruptions I ordered the avionics kit today.
Building has been a lurking dream for a long time.
To give you a clue, there is a Dyke Delta manual in
my library archives. As I always tell my wife, "it
doesn't cost anything to dream". Well that line has
run into some serious headwinds so now it has
morphed into "it cost a fraction of a combine". It
seems to be working and she is thrilled to see me
head to the shop for the day rather than pace around
the house foraging for hidden holiday snacks.
So come summer of 2018 I hope to transition from the
Warrior to the 12.
Overcooling the RV-8? (Warning – Long Post)
Guys I suspect we are overcooling our RV-8 engine
and suffering with excess cooling drag in the
process. We built and installed a nearly leak free
The James Cowling exit area appears to be huge in
comparison to the inlet area. The 2 round inlets
total 33.6 square inches and the exit measures 84.2
square inches. We plan to reduce the exit area
during the condition inspection in January, but the
question is how much? Is there an inlet/exit area
ratio that we can use as a starting point?
I did a test flight to collect a little data as

J-Turner Update Status
Today I made a support for the plane to sit on
while getting the wheel pants and gear leg fairings
Used a chair and some spacers at the rear and an
engine hoist to support the plane from the engine
mount to take measurements for the support. Made saw
horse style support 30.5" tall. This places the
wheels about 1/8" above the ground.
Then placed a centerline to take measurements from.
More pics tomorrow. On the right side I had to
enlarge the opening for the wheel to allow the wheel
pant to turn enough to be somewhat in line with the
centerline of the plane. Also tied the rear of the
plane down to my mini tug with ratcheting straps
because the engine hoist "leaks"down a little in a
10 minute span so, it's not up to the task of
supporting the front all by itself.
Wasted a lot of time rereading the instructions
trying to get the best alignment of the wheel pant.
Not much success today but tomorrow I might have
this thing right......
Another Stuck Valve
A year ago I had a sticky valve on #2. I was
going to do a precautionary check on all the
cylinders as soon as the weather turned bad for a
few days. Sunday was perfect weather in NE Ohio so I
planned a breakfast run of about an hour over some
rough terrain to W Va. My buddy canceled so I stayed
close to home. After 30 minutes of local flying #4
cyl went dead and I was able to land at a nearby
airport. Borscope revealed a perfect impression of
the exhaust valve in the top of the piston so I
pulled the cyl and the valve is very stuck along
with bent pushrod and tube. The piston feels ok but
I am having a qualified shop inspect everything. My
understanding is that this problem is often caused
be a poor hydraulic actuator so that will need to be
inspected also. 40 Year’s of flying Lycoming Engines
and never had a cyl removed.
Rotax Drip Tray
If the carb mount is removed from the manifold so
that it can be inspected, a raised area around the
flow path hole can be seen. It is basically a molded
in O-ring that will seal on the aft side of the drip
tray (if installed).
There is an o-ring in a groove on the intake
manifold that seals the fwd side of the drip tray.
If no drip tray gets installed, the manifold o-ring
compresses on the flange of the carb. mount
producing a double seal.
In the case were the o-ring was incorrectly
installed, the builder moved the o-ring from the
grove in the manifold and attempted to put it in the
very small grove that surrounds the integral seal of
the carb. flange. It does not fit... so it squirted
out during installation.
The statement "this should be used when the air box
drip pan isn't used" actually is indicating that a
drip tray is required. The airbox they are talking
about is this.
It is produced and sold by Rotax and is very
expensive. It attaches to the back of both carbs and
does away with the need for a drip tray because it
is a closed plenum that has nipples for connectiong
the carb vent tubes to. Note that it does still have
a heat shield for each exhaust pipe that has a place
for drain hoses which to me are pointless because
any fuel that ever drains from the carb will go into
the airbox. So what they are saying is if you are
not using the airbox, you should use the drip tray.
Help with slight loss of engine power/running rich
I have an RV-6, O-360, 850 hours, built it 2000.
On take off and climb out the other day it felt a
bit low on power. As I was climbing I started
leaning it a little and the power came up. It felt
like I was at a high altitude airport or like the
carb heat was on. It has not normally required
leaning like this before. I am basically as seal
level and 70-80 degrees. Something seems to have
changed. I checked to make sure the carb heat door
is fully closed and it is. I checked the idle
mixture (which understand does not really effect
full throttle) and I got a 20-30 rpm rise right
before shutoff idling at 1000 rpm.
This is the original carb and I have not touched it
since I purchased the plane. Been running fine. Is
it time for a carb overhaul? Could the float be
causing a problem. I know very little about the
internals of the carb but I can always learn.
Any suggestions on where to start troubleshooting?

Gear Shimmy Video Update ...Rusty
anyone playing along, I ended up replacing the tires
and tubes. I got a cheap balancer, and found that
the left tire was significantly out of round, and
would have required 2.5 oz of weight to balance. The
right tire was fairly round, but still would have
needed about 1.25 oz of weight.
The new 6 ply rated Desser Monster retreads with
Airstop tubes are nice and round, and spot on
balance. I literally couldn't identify a heavy spot
on either tire/wheel combo. I had to open up the
wheel pants a bit more to fit the monster tread, but
it's back together now.
I decided to remove the left stiffener too, even
though it wasn't loose like the right one was. I
figure I'll have them both be the same when I
install new stiffeners. For today's test, I had the
wheel pants on, but no gear leg fairings or
stiffeners. I'm going to leave the tires at 30 psi
since the goal is to fix the problem with the
I didn't note the groundspeed for the original test
in the video, but it was way faster than I hit
shimmy today. Today, I could feel them starting
around 7-8 kts, and by 10-12kts they were both going
wild. The good news is that this is exactly what I
would have expected, so it seems predictable. The
tires are heavier, so I effectively added weight to
the end of the "spring", and also made the spring
less stiff. Both of those changes would reduce the
resonant frequency, and that's just what happened.
Next step will be to install stiffeners as close to
Van's drawings as possible. They allow for mounting
these in front or rear of the gear leg, and I'm
going to mount them on the front side since that's
less in the way of my brake lines. With cold weather
and a distant hangar, it might be a while before

his last year. They also gave me permission to post pictures of his
aviation themed funeral. A sign shop wrapped the casket to match my
color scheme and they had a fly over with a missing man. First

Help me troubleshoot rough running
Ok, bear with me, this may be a long post..
2 flights ago, during a cold start (on a chilly day) the plane fired
right up and then quickly **** back down. This is abnormal for our
6. Normally always fires right up. Anyway, fired it right back up,
started fine, searched for idle for a bit but stayed running.. Good
runup, no issues. Went flying.
Today, the same deal. Fired up, shut back down, fired back up and
zero issues. Good runup, went flying. No issues.
Fly for about 30 minutes. Land. Plane sits for about 45 minutes,
crawl back in, fire it up (starts fine), decently short taxi out,
normal run up and depart.
While climbing out, above ~2250 rpm the engine starts running
rougher than I like, pull the power back to around 2100rpm and all
is fine. Turn downwind and land.
Taxi in and do a quick runup. Oil temps climb a littler higher than
normal, about 240*ish, and the plane runs s rough at 2200 rpm and
Taxi in, pull the cowl, look it over. Everything looks normal, but
there was a funny smell. Semi-electrical. Semi-heater on for the
first time in winter. Semi-burnt electric motor type smell. Not a
Let it rest, call our mech and he suggests mixture setting as the
first place to start looking. Mixture was slightly off. We set it
for about a 50rpm rise when killed from idle.
Do a couple quick run ups to about 2250rpm static and then idle shut
offs messing with the mixture.
Taxi’d back out for a runup just to see how it’s acting. Run up is
good until a few seonds into high power and it begins running rough
again. Rpms drop to 2000-2100ish. Back to the hangar. Smell is kinda
there, but nothing like the first time.
Call A&P and he suggests maybe it’s fouled plugs and to attempt to
burn it off.
Taxi out, attempt to burn off plugs with high power/leaning on the
ground and am unable to get steady enough running to really
accomplish anything. EGT’s got to around 1250. No improvement.
Pull the power back and just for grins, I checked the mags. Nothing.
No drop on either mag. Ah ha! I think. Found it.
Taxi back to the hangar and before shutting down, power back to
~1800rpm and check mags. Got about a 75rpm drop on both. Decent

Additionally, take some 150 grit sandpaper, roll it up where it will
go inside the pin holes and lightly hone the holes. Then do the same

video is pretty straightforward, but again, there's
no mention of doing anything with the shield.
Grounding it makes more sense to me, but I don't
want to redo this later.
I don't have anything else for the panel yet. Does
this wiring depend on what will be in the panel, or
is it standard?
Are you thinking of selling your aircraft? ...Gallagher Aviation
We wanted to remind you that most insurance
companies will short rate you when you cancel a
policy, but sometimes we can work around this. If
you are thinking of selling your aircraft, ask the
buyer to contact us for a quote. If we are able to
write the buyer with the same company that you
currently have, we have a much better chance of
talking the insurance company into prorating your
cancellation. It’s a win-win for everyone! You will
get more of your remaining premium back, the
insurance company gets to keep the business and the
buyer will be working with a Vans specialist who
will find the best options available to them. Even
if we are unable to write the buyer with your
current company, you are doing them a favor by
introducing them to an insurance broker that prides
ourselves on having close relationships with our
underwriters to make sure your policy is the best to
fit your needs. We also have an in-house claims
advisor to work for you, and we were just mentioned
as the World’s Most Ethical Company for the sixth
year in a row. Remember, our business is built on
referrals. The biggest compliment you can give our

Gear Shimmy Reduction Testing Plans ...Rusty
For further entertainment, I decided that I'll try
to keep this thread updated as my testing
progresses. It may take a while since the hanger is
a looooooong way away, and it's winter.
The last time I was at the airport, I removed the
fairings to see what sort of stiffeners exist.
They're not exactly as specified, but at least they
were in the ballpark. The most obvious problem is
that one of them had come loose from the gear leg,
and since the leg is tapered, it slides down, and
becomes even more loose. I'll give you one guess
which one that was
I cut the loose stiffener off, and besides coming
loose, it was also coming apart, and the ends were
somewhat water rotted. The other one appears to be
pretty solid, though there is some hollow sound as I
tap on the upper end. Since I could never stand to
have the two not match, and since I figure that one
has some water rot as well, I'm going to remove it
on my next trip, and plan to replace them both.
I also brought the fairly well worn Condor tires
home, and have a motorcycle wheel balancer on order.
If the tires appear round, I will balance them as
best I can, and then reinstall them. If they are not
round, I'll order new tires. The Desser monster
retreads seem to be well recommended.
The first step in my experiment will be to install
known round and balanced wheels, but no stiffeners,
fairings, or wheel pants for the next flight. I'll
try to determine if there is shimmy, and if it's at
a higher or lower speed. Sadly, I didn't note the
GPS ground speed when it happened before, but I have
a pretty good feel for it.
Following that test, I'll install the wheel pants
for another test, then stiffeners, and finally
fairings. I really don't think the gear leg fairings
will have much effect, so I'll probably try to get
it shimmy free before installing those.

I am new to building and have a quick question about
subbing in a cherry rivet for an standard flush. If
this topic has already been in a post let me know
and I will have this one removed.
I am about to prime and rivet my HS and a useful
trick has been mentioned and I would like to know
its validity. Is it common practice to substitute a
standard flush rivet for a pulled rivet in these
tight spaces where a standard slim bucking bar even
has a hard time getting to? I have seen/heard of a
few tricks for these locations, but feel a pulled
rivet will have the least likelihood of me causing
damage. I understand there will be a small amount of
filler/sanding required to clean up the head of the
pulled rivet to keep my skin looking smooth. I
inserted a few pictures of where it might come in
handy. Like I said, I am only priming my HS and have
not yet even looked too far ahead. Just circled a
few parts on the plans that look a tad...snug.
RV-12 SB 16-05-23 PIREP ...Peterk
I removed my wheel pants over a year ago just to
be able to look for a nose gear crack prior to each
flight (and after) My RV 12 was one of the first ten
built (2009) and now has close to 900 hours of
I flew from North Texas to Norman Oklahoma yesterday
and back. After returning I found a crack exactly
where the lower circle is on SB 16-05-23. It was NOT
there when I left Norman. I have always used
virtually full-stall landing techniques and never on
I was debating if it was a function of poor landing
technique, hours or just poor design. Still don't
know for sure of course but my greatest fear was
ripping off my prop so I was anal about checking it.
That part worked out.
Keep on eye on yours.
Ok, I’m not sure why I feel like I’m struggling
with the Front Spar on my Empennage, but here it is.
I countersunk HS-710 and HS-714. I think I may have
gone a little too deep in an attempt to make the
dimples on HS-702 fit into the countersunk hole. I
know section 5 says 7 clicks past flush is the
proper depth, however it didn’t seem like the dimple
fit properly. Attached is a link to a picture with a
AN426AD4 rivet inserted into the hole for reference.
I’m worried I’ll need to order new reinforcement
angles. What are your thoughts?
Is My Engine Broken In? ...Rich/Cindy Macrofic
Background: Just completed RV-7A. IO-360 engine
new. Started with 7 qts of oil, with the assumption
that the better part of 1 qt would go to the oil
filter. At 2.0 (tach)/3.5 (hobbs) hrs, I added a
quart of oil. Probably could have waited another 2-3
hrs, as not quite a quart had been consumed. I now
have 13.8 (tach)/16.8 (hobbs) hrs and am not needing
to add additional oil yet. Maybe another couple of
hours? So, in summary, I have 11.8 (tach)/13.3 (hobbs)
hrs on this last quart of oil.
CHTs are behaving, but I did not unfortunately
record the very initial CHTs at a particular power
setting for a current comparison. As a result, I
don't know if I have experienced the 50 degree drop
in CHTs that I have heard about (as another
indication that the engine has broken in).
In trying to summarize the various VAF posts on oil
consumption, it seems to be the general opinion that
10 hrs per qt is a pretty decent consumption.
Obviously, some are getting less and some more than
that. So, I am definitely above that. I have read
Lycomings documentation, but they only specify the
max allowable oil consumption, not a desirable
range. They also only specify a maximum schedule for
mineral oil (25 and 50 hrs), with a stipulation that
the key criteria is stabilized oil consumption.
So, the questions I am pondering. With so few hours,
could the engine already be broken in? The oil has
gotten much darker the last couple of flights, so I
would like to change it. Should I again use mineral
oil or go to standard oil?
Anybody have any other
perspectives/thoughts/experiences that I should
contemplate as I make these decisions? Any thoughts
Solidworks, Vans 3D models, and Garmins 3D models
Ok, this is just plain cool. With Van's recent
release of the 3D models for the fwd fuselage area I
decided to start playing with a panel design for the
RV-10 I am building. I downloaded the RV-10 3D
model, the Garmin avionics 3D models and started
plugging things together. I'm nowhere near done but
even with this simple picture you can see the
potential for this. The images on the avionics are
just screen shots I took and placed on the screens
for a coolness factor.
Cannot Transmit Only Static ...Stan Bahrns RV-7A
My Push to talk on both sides has so much static
on both sides now that I am not able to transmit at
all but receive very well.
I have checked all the connections on the headsets &
wiggled everything I can think of even pulled out
the skyview but didn't find anything. Does anyone
have any idea where or what I should do to find the
problem? It seems like there is something that
switches when the push to talk switches are pushed
that don't switch completely. If anyone has had any
problem like that? If so it may help me know where
to stare looking for the problem.

Reflections on the Build ...Jpm757
Thirty years ago I got the BUG. Past all of the
flashy Lancair and Glasair ads in Sport Aviation,
there was a small black and white ad for Van`s
Aircraft, "Total Performance" it stated. If true, it
was exactly what I was looking for, so I decided to
pay a visit to North Plains, OR, and the modest
facility of Vans Aircraft. I met Van and was shown
the RV3, 4 and brand new RV6 prototypes. The weather
was lousy so I didn't get to fly that day, but I
sure liked what I saw and plunked down a deposit for
an early RV6 kit. 2 years and $29,000 later I was
the proud owner of one of the first flying RV6`s.
Boy was that a great airplane, and I enjoyed it for
15 years. When I reluctantly sold it. I sure hoped
I'd get another.
Fast Forward to 2016 when a friend had an RV7 QB kit
that had to go. Just like that I was back into
homebuilding! My son had been bugging me for years
to get another RV, so he was totally on board. It is
amazing how much has changed in 30 years, QB kits,
pre-punched everything, and aftermarket vendors by
the dozens. Of course there was also the internet
with its wealth of information. All of this combined
with the incredible community of RV builders made
the new build a pleasure. Still a lot of work and a
lot more expensive these days, but 14 mos. later we
had another flying RV. What a great success story
Van's has become, but yet I still feel they are
still the same mom & pop operation they were 30
years ago - and that's a good thing.

This isn't RV-related, but I thought some might be interested.
My wife's car threw a Check Engine light Saturday, and since it's a
10-year old car I'm thinking O2 sensor. A friend at the
airport suggested looking into the Bluetooth OBD-II scan devices
that plug into the OBD-II port, so I did. A few reviews later
I ordered a $99 BlueDriver from here and downloaded the free app. Hardware arrived Monday
night...problem fixed Tuesday morning (it wasn't the O2 sensor).
Reset the codes via the app. It has already paid for itself,
and it goes w/o saying that my friends at the airport are going to
want to borrow this when their cars throw error codes ;^).
If you like looking at graphed engine data from your RV, you might like
this for your cars (if they were built after 1996 - when the
standard was made mandatory for all US-build vehicles).

RV-12 Documentary? ...Paul Straub video (1hr 5min)
Don't know what else to call it....I never did a 'blog' but now
that my build is over, I wanted to document the story somehow. When
I was considering building an RV-12 a couple years ago, I watched
Dave Gamble's "Building a Van's RV-12" on YouTube and that is what
pushed me over the edge (in a good way) to build the plane. I'm
hoping this might help someone that is just thinking about building
or on the fence. If you ever can't sleep and are willing to give up
an hour of your life that you can never get back, it may or may not
be interesting, but this is the story of my build.
Sunset over MN ...Alex Peterson
This was simply too amazing not to share, taken tonight over
Vadnais Heights, a NE suburb of the Twin Cities. The view is towards
the SW, with Vadnais Lake just touching the wing, and Lakes Wabasso
and Owasso a bit further in the distance. This view lasted only a
minute or two. This was one of the best I've viewed in the 16 years
this plane has been flying!
Water leak from underside
My 6A is pretty tight up top, even with a tip-up. I posted
previously about a 3 piece fiberglass tray which prevents any
leakage from the front canopy seal from making its way into the
instruments, although the canopy seal rarely lets any water in.
Flying some practice IMC approaches the other day in heavy clouds
with 700' ceilings resulted in water dripping out of the drain holes
in the bottom of the fuselage, specifically the forward most drain
hole which is centerline, just aft of the seat back bulkhead. I'd
say that approximately a pint of water leaked out after I parked the
plane in the hanger, following about 1.5 hours in the clouds (no
rain just lots of moist humid clouds).
I found this extremely disturbing and set right away to identifying
the source of the leak, while everything was still wet and I could
hope to track it. Off came the seat backs, floor panels and the
baggage bulkhead panels. I figured it must be coming from the wing
area, even though I had sealed the outer floor ribs to the skins at
construction which had been recommended. I found that virtually the
only evidence of water was along the center of the aircraft, between
the two ribs which create the tunnel for the elevator pushrod. The
drain hole is in the baggage compartment portion, but there was also
water in the portion of the tunnel forward of the compartment in the
seat area and even the aft part of the insulation in the center
tunnel of the floor area was very wet. No evidence of it coming from
outboard and working its way to the center. Aft of the baggage
bulkhead was virtually dry, with only a few drops of water visible.

EGT and CHT at WOT
Not sure if this is a problem but its not something I have
experienced yet. At WOT on takeoff, my #2 cylinder egt rapidly
climbs to 1560 deg and the CHT also goes up more than the other
cylinders. After leveling off and setting cruise power, the temps
come down but #2 is always warmer than the other cylinders. I
removed the air dams in front of #1 and #2, checked for induction
leak, borescoped #2 cylinder but do not see anything out of the
ordinary. Fuel flow seems adequate and engine is very smooth
running. Any ideas? The engine is an O320 150HP and has about 15
hours SMOH on an RV6A
Takeoff and climbout WOT.
Self-discharge or parasite drain?
I've had an EarthX ETX680 in my project for many months now.
Usually it is on the Optimate charger they recommended. A few months
back I unplugged the charger to move some things around. I went to
start avionics today and the battery was dead, showing 7v. I charged
and it came back to 13.65v but I'm trying to figure out what could
be causing this.
This happened over maybe 3-4 months unplugged. The battery is in the
plane and everything is wired up but the master is off. There should
be nothing draining the battery, and if I put an ammeter in-line
with ground I see 0.000A going through it.
What am I missing? Their install doc claims a discharge at ~3%/month
so it should not have been a self-discharge problem.
Here is my wiring diagram:

Milestone ...bruceh RV-9A
I have been flying my RV-9A now for 500 hours. We hit it
coming back home from a nice long
Veteran's Day weekend trip to Texas and Big Bend National Park.
I realize 500 is just an arbitrary number, but it got me thinking,
what sort of maintenance items should be looked at more critically
as I hit the first quarter of my engines TBO. Is there anything you
would focus on to inspect or replace just based on engine hours?
Tires and brakes are recent. I do oil changes every 35-40 hours. The
plane has been flying for under 4 years (around 140 hours per year).
My annual condition inspections have been uneventful. I've got P-mags
and the automotive spark plugs get replaced each year. At some point
I know things like seals, hoses, spark plug wires, control cables,
etc. will need to be replaced.

Why the Big Hole?
Q: Drilling the hole in the tailcone
aft bottom skin for the tiedown. Instructions say drill it to 11/16.
I got to 1/2" and it already seems too big. I'm going on the
assumption that just the eye bolt has to pass through. Why
would they want it bigger?
A: And best practice for installing
the anchor is to thread a 3/8" nut on it all the way and then
install the anchor.
The nut allows for adjusting the alignment of the anchor and it
extends it a little lower to help assure that the anchor will be the
first thing to touch in a tail strike.
The bigger hole allows for the nut.

Vinyl Wrap Weight ...Bevan
I weighed a square foot of vinyl (3m-1080) and multiplied that by
my calculated surface area of the entire airframe. The calculated
result was 17lb. I rounded that up to 20 to account for some overlap
and estimating errors.
A local pro aircraft painter and I had a "why vinyl" versus paint
discussion and weight came up. He confessed that an RV he recently
painted in three colours base/clear system probably left 55lb of
material on the airplane.
Even if his estimate was high by double, the vinyl is still lighter.
BTW, I ended up painting most of the fibreglass parts to color match
the vinyl including engine cowl, spinner, wheel pants and wing tips.
Breaking the Mishap Chain: Human Factors Lessons Learned from
Aerospace Accidents and Incidents in Research, Flight Test, and
...free e-book from NASA (updated August 2017). This volume
contains a collection of case studies of mishaps involving
experimental aircraft, aerospace vehicles, and spacecraft in which
human factors played a significant role. In all cases the engineers
involved, the leaders and managers, and the operators (i.e., pilots
and astronauts) were supremely qualified and by all accounts
superior performers. Such accidents and incidents rarely resulted
from a single cause but were the outcome of a chain of events in
which altering at least one element might have prevented disaster.
As such, this work is most certainly not an anthology of blame. It
is offered as a learning tool so that future organizations,
programs, and projects may not be destined to repeat the mistakes of
the past. These lessons were learned at high material and personal
costs and should not be lost to the pages of history.
Status Report ...David Paule RV-3B
Before I could rivet the long belly skin, the side skins need to
go on. The bottom of the belly skin was already riveted to the
various stiffeners and bulkhead flanges, so the only remaining parts
were at the ends and the bulkhead shoulders, and they can wait till
I do the lower longeron and bulkhead riveting for the side skins.
The tape bumps roughly in the middle are folded-over tape, giving me
aen easy place to grab on to for removing the tape. I now like 3M's
model 33 electrical tape. I've tried blue painter's tape, which is
harder to remove, and green painter's tape, which is fine if there's
a wider area to tape but is slightly harder to remove. However the
green painter's tape conforms down into the dimples better.
One of the steps to this gluing is to mask off the areas adjacent to
where the glue goes and then do a dry fit check to verify that the
tape is in the right place. At the upper left, you can see that I
needed to adjust this a bit. The tape is slightly apart from the
joint so that I can form the glue squeeze-out into a fillet there.
Refurb Status ...BruceMe
The canopy on there now is 100% sikaflex built ~2006 (about 2 yrs
before first flight). I honestly did a messy job. Others have posted
better work. My canopy has never cracked or de-bonded to the frame
despite really awful abuse. The "non-critical" skirt which I
sikaflex'd as well, has de-bonded when the canopy slammed open rev'g
to taxiing in wet muddy grass. I will rivet the skirt to the frame
as well as sika. I will also repeat the Sika with this canopy re-cut
project as I do really like it. I'll likely have to carefully
die-grind (scotchbright wheel) off the old Sika in some spots, but
I'm mostly cutting down the existing glass.
This is what I plan to do to the canopy...
Argument FOR filling empty hole with rivet ...Tdeman
Without knowing the exact circumstance (regarding where the hole
is etc), the one question that can be addressed is:
"So, will driving a rivet do anything to restore part of the lost
strength in this longeron?"
We'll see the greatest effect of this rivet
compression, where it will in fact carry
some compressive loads.
That being said, there is still a benefit of having the rivet in the
hole while the longeron is in tension, as pointed out in the article
shared above by Kurt W (as well as other texts on mechanical
behavior of materials...)
In case anybody didn't read the whole thing
, one part that stood out is...
"Both cold working and
interference fit fasteners set up
residual compressive stress fields in the metal immediately adjacent
to the hole (Fig. 14.26). The applied tension stress during fatigue
loading must then overcome the residual compressive stress field
before the hole becomes loaded in tension. The fatigue improvement
due to cold working in 024-T851 aluminum is shown in Fig. 14.27"
Rear Seat Heat ...DonPro
In my 6, my wife often wears a jacket and wants the heat full on
and I am down to a T-shirt and still warm so I knew the 8A would
need rear heat. Learning from the 6 I have aileron and elevator push
tube boots to seal the tunnel. I had Larry Vetterman make both of my
heat muffs and control boxes with 1.5" outlets which works great and
he did for no extra charge but 2" will work too. The key part is
made on a piece of 1/2 X 3" pine that is actually 1/2 X 2 1/2" from
Lowes which I routed two corners off of. I rapped it with packing
tape and put PVA release agent on it but it was still a bear to get
the wood out when done. I had to drill it some. The inlet is
leftover 1.5 push tube from the kit. At full deflection there is
still 1/8" clearance and a plethora of hot air is coming up between
the backseater's legs. Full disclosure, I am preheating my heat muff
air with the oil cooler to save on cooling losses in the summer but
you may not have to. My heat is very hot though!

Air to Ground Freq.
I took my RV-10 up on its first flight this past Saturday, and I
was talking to my father on the ground with a handheld tuned to
123.45. Mostly I was keeping him informed as to what I was doing and
how the plane was behaving, but 10 minutes in someone broke in with
a curt 'Get off this frequency!'
It's my understanding that 123.45 (known as 'fingers' apparently) is
reserved for air-to-air and civilian flight testing, so I'm not sure
who I was intruding on or if that person had any business telling me
what he did.
What's the proper frequency I should be using to communicate with my
ground crew while flight testing?
Trailing edge rivets
My instructions said straight trailing edges was one of the most
difficult parts of building a flying surface. With that in mind, and
being far from accomplished with the rivet gun, I decided to find a
way to get good reliable results with a dead straight trailing edge.
I'm accustomed to building race cars in jigs and fixtures so Van's
"in the air" method is all new to me, and a little scary. Point is,
I'm blessed with tools and equipment most of you do not have and do
not want to buy. One of them is a six foot by six-foot by .625 steel
blanchard ground surface plate flat and square to .010. With this

Got to thinking about flat tires on the RV-6.
I had a right main tire blow out in the air on a Beechcraft V tail.
The landing was sporty. As I slowed, the drag to the right was very
Full left rudder did not stop the drift to the right. Only when I
applied left brake was I able to stop the drift and keep it on the
So, as I think about my new RV-6, I could imagine a flat tire could
easily lead to a ground loop on landing.
Has anyone here experienced a flat tire when landing a tailwheel RV?
Were you able to keep the bird from ground looping?
I'm thinking a 3-pt landing would be better than a wheel landing in

Structural Benefit to Filling Hole With Rivet?
a dumb question, but I wouldn't want to disappoint my friends.
I have a 1/8" hole in a longeron that I no longer need due to
change of plans. It would certainly look better if it had a rivet in
it, but with the curvature of the rear fuselage skin this is not an
easy slam dunk operation. Its not in one of those places where it
will stick out like a big "DOH!" sign. At the same time, I don't
like anything weakening the structural integrity and especially if
its not doing anything beneficial.
So, will driving a rivet do anything to restore part of the lost
strength in this longeron?
Running wires RV8
A: According to the document linked below, installing
a driven rivet produces a local area of residual compressive
stress in the material surrounding the rivet, resulting in
improved fatigue life for certain loading conditions. See
section 14.11, pages 18-19:
As with everything, a bunch of caveats apply. Care must be taken
to also consider the, adjacent structure, maintaining proper
fastener spacing to adjacent holes, etc. Whether or not fatigue
life is a concern given the part properties and loads is another
A: On a fighter jet, or an airliner, there is
much effort spent at making every bit of structure as light as
possible. Skins are chem milled to thin them in areas where they
are not loaded. spar caps are tapered etc etc etc. On an RV the
longeron is the same size and cross section throughout its
entire length. It probably only has to be that size for a very
small portion of its length. In fact, when he was designing it,
Van might have sized the angle and then used the next size up,
because you can't buy a 37/64" angle that is 7/64" thick (I
invented those numbers). The extra material is left in, because
who is going to bother trying to get it perfectly optimized.
If you want to do a major stress analysis at each hole, go
ahead. It's your airplane. And drilling a hole does reduce the
cross section and therefore makes it weaker in tension by
definition. But this is only a problem if that part is optimized
to be exactly as strong as it has to be. The longeron will be in
tension at full rudder 1 way, and compression with full rudder
the other way. Same with pitch up vs pitch down. So if you
increase the compressive strength for left sideslips, but you
don't address the reduction in tensile stress in the other
direction, you have not made the structure any safer.
I would only really worry about holes in the longerons up near
the steel gussets that tie them to the firewall. That would be
the area where they are most highly loaded and there are 4 -3
bolt holes in them. An AD4 rivet hole further down is not going
to compromise flight safety.
No, I am not a Vans employee but I have been an Aero Eng for 28
yrs and I do know something about loads and aircraft structures.
And I have a 4 that has some holes in places they shouldn't be

about it here in Aurora. We frequently learn about airplanes that
flew many years ago, simply because the builder never shared their

Therefore, we have temporarily suspended
updates to the Flying RVs page on our website. At some point soon,
we will receive the first flight report for the airplane that will
be deemed to be the notional 10,000th RV, and announce the event. We
anticipate that it will be in December sometime, if we continue to

Update on SB 16-12-16 ...Andy Karmy
Just a quick update to this old thread. I had the "pleasure" of
helping a good friend install these 12 bolts this weekend! What fun.
Once he had all of it opened up and removed the center control
column and sticks I was ready to work. Took 5 hours. We were able to
get all 12 in without any holes just using the center access hole.
10 of them went in from the back (inside the spar box) and 2 had to
go in from the front due to interference with the nuts on the rear
spar that hold the seat rib in place.
The only thing that we found to work was to use a camera (I had a
cheap USB camera) and put it on a stick. Then use 12" forceps with a
slight notch ground in about 1/4" from the tip to hold the bolt.
Then with one hand on the camera and one on the bolt you put it in
the hole (Mars rover style)
Boy it feels good to have the last one go in place. And the defeat
you feel when you bump the bolt that's half way in the hole is real
But in the end it's doable if you have the right tools at hand.
Thanks to those of you that posted above, we took lots of those
ideas in mind before starting. (now how long will these bruises take
to heal on my forearms).

Replaced with the same AN5-20A bolt per plans added an extra thin
washer and used red Locktite on threads. Surprisingly there was no
play after cleaning out the hole in the engine mount and the gear

would gladly mail it. It would be interesting to know how fatigued
the bolt is and how far it is from the failure.

ADDRESS TO FELLOW-COUNTRYMEN
The White House, November 11, 1919.
year ago today our enemies laid down their arms in accordance with
an armistice which rendered them impotent to renew hostilities, and
gave to the world an assured opportunity to reconstruct its
shattered order and to work out in peace a new and juster set of
inter national relations. The soldiers and people of the European
Allies had fought and endured for more than four years to uphold the
barrier of civilization against the aggressions of armed force. We
ourselves had been in the conflict something more than a year and a
half. - With splendid forgetfulness of mere personal concerns, we re
modeled our industries, concentrated our financial resources,
increased our agricultural output, and assembled a great army, so
that at the last our power was a decisive factor in the victory. We
were able to bring the vast resources, material and moral, of a
great and free people to the assistance of our associates in Europe
who had suffered and sacrificed without limit in the cause for which
we fought. Out of this victory there arose new possibilities of
political freedom and economic concert. The war showed us the
strength of great nations acting together for high purposes, and the
victory of arms foretells the enduring conquests which can be made
in peace when nations act justly and in furtherance of the common
interests of men. To us in America the reflections of Armistice Day
will be filled with - solemn pride in the heroism of those who died
in the country’s service, and with gratitude for the victory, both
because of the thing from which it has freed us and because of the
opportunity it has given America to show her sympathy with peace and
justice in the councils of nations.

RV-12 Winterization Kit (optional)
RV-12 coolant radiator and oil cooler block-off plates for use in
cold climates when ambient operating temperature is below 50°F
The use of these block-off plates allows the oil temperature and
coolant temperature to be maintained within the normal operating
range during cruise flight and improve cockpit heater performance.
With the RV-12 not having an oil or coolant thermostat, it is not
possible to add winterization parts that will properly regulate oil
and coolant temperatures at all temperature conditions.
The use of this winterization kit will require any pilot flying the
aircraft to actively monitor the engine temperatures and make
adjustments to the installed parts, to coincide with air temperature
changes that are common from one day to another. Example - It is
possible that at warmer temperatures, a particular airplane may
allow for partial blockage of the radiator with the Radiator Cover,
but require that no Oil Cooler Cover be installed.
Steve Smith VFR-->IFR PIREP
Out west here, one likely scenario of VFR into IMC is with fire
smoke. I've made some pretty marginal flights. On one of them, the
vis went from 5 miles and a good horizon to 1 mile and no horizon
fairly quickly. But not instantly like going into a cloud. It gives
you a little bit of decision time, but you better make the right
decision. I had started a descent to maintain good sight of the
ground ( I knew I couldn't get on top of it because I knew how high
it went) so I made the descent much more aggressive, and turned
On another occasion, I was flying east across basin-and-range
country with 4 mile vis, but the periodic ridges crossing in front
of me gave me a good horizon. At a certain point in central Oregon,
the ranges stop and it is just a big basin, which happens to be the
same color as the smoke. Now no horizon. In this case I climbed
until I had a good horizon on top, although I could only barely see
the ground at all.
For me, the key is recognizing the evolution of the conditions and
acting soon enough to prevent a complete loss of horizon or ground
vision. It is a bit different with smoke because it happens
gradually, not suddenly like going into a cloud. But that also makes
it insidious. Its easier to say I will keep going unless it gets
worse, and it keeps getting worse. And of course next time I might
not recognize the trend and make a good decision soon enough.
The "experience" I've gained from these is two-edged. Part of me has
gotten more conservative and more willing to turn back. But part of
me has gotten more confident that I can recognize the situation and
react accordingly. I have to remind myself that this is dangerous
stuff, and this thread is really good.
To Dan's point, although I am not instrument rated, I have done a
lot of hood work, including a BFR two years previous with 1.5 hrs
under the hood with lots of extreme attitude recovery. The rub is
not having appropriate equipment in the airplane.
With the advent of glass cockpits, it is now more common to have a
good artificial horizon. But I really favor old-fashion round
gauges. I don't want a vacuum system. So for now, I have just a
Trutrak ADI-pilot. But it is not a "real" AI. It synthesizes AI
information from rate gyros updated with other sensors. I'd like to
think it would be a good fall-back instrument for inadvertent IMC,
and I have practiced a little with it, but I find that it does not
always know correctly which way is up. (maybe something wrong with
it?) An electric ADI is pretty expensive, but I am pretty seriously
considering the investment. Or perhaps succumb to the glass side and
get a Garmin G5.
AOA Pitot RV-10 Install Pics/Words ...Bill Peyton
I installed the AOA pitot in the Van's specified location with no

the wires and cable tied. I ran a couple of extra wires down to the

Mountain Rotor Diagrams ...Carl N.
I've flown mountain wave in sailplanes, and the wave is usually
very smooth since it is a laminar flow phenomena (requiring a stable
atmosphere) and forms above the convective layer. The rotor is
caused by friction with the ground, and can be extremely turbulent.
If there is enough moisture in the air, the rotor will be visible
with a cloud forming at its top and should be avoided.
When flying wave in a sailplane, you basically stationkeep in the
lift areas of the wave (watching the ground drop away), climbing
past the leading edge of the lenticulars, if they are visible.
Notice that there can be Primary, Secondary, Tertiary, etc., bounces
of the wave, depending on the wind strength, angle to the mountains,
and stability of the atmosphere.

"Van’s Aircraft has always prided itself on customer support. One
aspect of this support is our commitment to continue the ready
supply of parts for older models that have been superseded in design
and ease of assembly. The RV-3, RV-4 and RV-6 were the basis of our
product line for quite some time. In recent years we have seen their
respective kit sales decline significantly. Although kits and spare
parts for these models remain in our inventory, the cost to produce
and warehouse parts that rarely sell is ever more burdensome.
Therefore, to mitigate the costs and logistical difficulties that
arise from low sales, we must adjust our production, pricing and
This is to inform builders of these models that prices for these
kits will significantly increase after January 1, 2018. Production
runs for these kits will not cease, but the period between them will
increase dramatically. We estimate production gaps of one year or
more that can easily translate to delivery dates of one to two years
from date of order.
We at Van’s want you to continue your project to completion and
therefore suggest that you place an order for an empennage, wing,
fuselage or finish kit now at current prices. If we receive enough
orders for these kits beyond current inventory by years end, we will
institute a production run to cover them all. This will yield
reasonable delivery times. Spare parts will also remain available as
supplies last. However, once depleted, parts may still remain
available, but will be produced on a one-off basis. Production of
any one part is expensive so an elevated price compared to a similar
part in another model RV is to be expected.
Kits available for order are:
RV-3 Empennage, Wing, Fuselage and Finish
RV-4 Empennage, Wing, Fuselage and Finish
RV-6(A) Fuselage and Finish
Current prices will remain in effect for all kits ordered prior to

So there I was, several years of instrument currency and even
flirting with proficiency every now and again. Weather triple

reporting OVC 1700 double checked visually, I'm sure center is gonna
be busy given the conditions but I don't want to spend an extra
20-30 minutes picking up my clearance via FSS. It's a familiar
airport with no terrain and with 1700 OVC I was more than
comfortable departing VFR.
Normal startup, runup, taxi and takeoff with my course and
frequencies pre-loaded. As I turn on course and switch to center
frequency it appears my 1700 OVC/VIS is obscured with some newly
formed mist and lower clouds so I level off at 500 AGL to stay clear
of clouds. I momentarily thought about returning to land and pick up
my clearance through FSS but press on because it's familiar
I confidently called center requesting my IFR clearance, center was
busy and I eventually received a "sqwuak and maintain VFR" currently
15 miles from my departure airport still at 500 AGL. Because of my
low altitude I can only hear center with the squelch on and seems my
transmits are broken as well, I know the farther I go the worse the
frequency gets at low altitude.
30ish miles (minutes at RV speed) from my departure airport I still
don't have a clearance and even with the squelch on I can barely
catch half of what the controller is saying. Seems a NASA test
flight is non-radar in a low block altitude in my vicinity that also
can't hear center on frequency. Again I contemplate turning around
but my closest airport is 30 miles away. Surely I'll get a clearance
soon, I press on watching my terrain page as a clearance in a couple
minutes is safer than flying back at 500 AGL.
I wasn't shy about my clearance request at this point and eventually
had my IFR clearance relayed through another aircraft after center
finally determined the NASA test flight position, an IFR clearance
never felt so good.
How did I rationalize myself into this situation, as always it was a
chain of events:
-didn't want a FSS delay
-1700 OVC was comfortable for departing VFR and pick up clearance
-squawk code and talking to center feeling I would get a clearance
-I've got a squawk and ATC is expecting me to be on route
-I'm too far away to turn back
-If I could just get my clearance I would be fine
Looking back when I hit the OVC/VIS at 500AGL I should have turned
around and landed. I wouldn't think of departing without an IFR
clearance in 500 OVC yet I rationalized and flew for 30ish miles
because. Judgement isn't taught, it's gained through experience.

Mountain Flying - More Lessons Learned ...pvaslovich
Saturday afternoon passenger drop-off flight over the Southern
Sierra Nevada Mountains from Inyokern (IYK) to Kern Valley (L05) -
less than 30 miles. Wind 260/12 at IYK. Climbed to 8500 in clear
skies to safely clear the two major ridgelines enroute. A little
bumpy, but nothing unusual for the Southern Sierra. Uneventful leg -
except noting winds were on the nose at 42kts at 8500 ft.
Return leg at 7500 ft. Fewer bumps than first leg until lee side of
westernmost ridge. First roller banged my head off the canopy
(thought I was tightly strapped in - but I was wrong) and induced an
uncontrolled right roll. Second roller immediately thereafter
continued roll with nose down pitch. Ended up about 120 degrees
right wing down, 30 degrees nose low, accelerating. + 4.5, -3.1 g's
on the g meter. This occurred within 2-3 seconds under clear skies,
in pretty calm air with no warning.
1. Be wary of ridge crossings with high tailwinds.
2. Ensure you have enough altitude for recovery from nose low
3. Be comfortable with sudden unusual attitude recovery (I'm a
former Navy A-4 Adversary pilot; joke about being more comfortable
upside down than right side up).
4. If you suddenly find yourself nose low with excessive bank, roll
wings level before pulling to the horizon - otherwise you risk
increasing bank into a tight nose down spiral.
5. Be aware of your nose low airspeed - Vne is a real number.
6. Clear skies does not correlate to smooth air in the mountains.
7. Be wary - and prepared.

RV-4 Firewall Wrinkle Update ...from other -4 owner (Vac)
It's fairly common for -4's to suffer wrinkling in the lower
corners, usually as the result of a hard landing load or continuous
operation off of rough surfaces. The aluminum fuselage structure
flexes under load (as it's designed to do), but the hard stainless
firewall suffers stress wrinkles or cracks. As long as there is no
permanent fuselage primary structure or landing gear leg
deformation, the firewall itself is non-structural. If the stainless
has any holes or cracks, they should be smoothed and/or
stop-drilled, as appropriate and filled with high temp silicone to
preserve firewall integrity.
Similar to your situation, I also watched my brand new replacement
lower RV-4 firewall crack in the lower corner within a few landings
because I didn't "pre-stress" the lower firewall thru-bolts...i.e.,
before drilling the replacement firewall rivet holes and riveting,
use a nut, bolt and fender washers to properly compress the
stainless in the corners to mimic the compression imparted by the
engine mount. So that would be my primary suggestion in addition to
adding the RV-8 style gussets as suggested by Van's!
Likely you are already aware, but be sure to check the engine mount
for any cracking as well, since the same stress that induces the
firewall wrinkling causes stress at the welds in the gear leg
sockets. Engine mount fatigue cracking is not uncommon (mine cracked
at about 1100 hours). If your mount is finished in black
powder-coat, visual inspection can be difficult, and may require you
to remove the powder coat in suspect areas to make a determination.
If the engine mount is dark, sometimes the presence of a small
amount of grease at the weld can provide a visual cue that the weld
may be cracked. If the weld cracks, it's possible for some of the
grease to be forced out of the gear socket through the failed weld
as the area flexes during taxi, takeoff or landing. Given the
option, a painted mount that uses dark primer and light finish color
can simplify visual inspection.
RV-10 Top Antenna Reinforcement ...Bill Peyton
Because there is a slight curve where you are mounting it, if you
make a stiffener it will flatten the area above the stiffener and it
will show. Ask me how I know. What I ended up doing is creating a
stiffener that is fastened to each stringer, I then made shims and
installed washers between the aircraft skin and the stiffener so the
shape of the outer skin is unaffected by the stiffener. You will
never notice the slight leaning of the antenna. The antenna is
extremely stiff doing it this way

doing what every mishap pilot does, looking out the window searching
for the ground. I was lucky and learned from the scare. For 30 years

It works fine, just slide the lever on the sidewall to balance

Status Report ...David Paule -3B
Today's job was to glue the long belly skin to the fuselage. I'm
using G/Flex epoxy, the thickened variety, which has a 45 minute pot
life. A dry run showed that it took me 1/2 an hour to get the skin
and the hardware all set up, so I knew I needed some assistance.
Dave Dooley stopped by to lend a hand.
The skin and substructure was ready to go, with tape on and the
cleco tips oiled.
I mixed up a couple tubs of the glue and we started buttering it on.
It went to the perimeter and the shoulders of the bulkheads. Then we
lifted the skin into place and with the exoskeleton, started
clecoing it all together. We only needed one cleco every four rivet
holes but we added a few more, here and there, for assurance.
Then we wiped the epoxy off the tips of the clecos and pulled off
some of the tape and made fillets at the edges of the joints. Dave
left and I took this not-so-great photo.

Hurricane Damage Q/A ...Greg B.
Q: In preparation for Harvey I put my nearly completed fuse up on
a table, resting on a piece of old brown carpet. While we did not
get flood water in the garage nevertheless somehow moisture got
between the carpet and underside of the fuse. This I discovered
yesterday(so about 2 months) when taking it down in prep for
prime/paint the interior. The carpet stained 2 approx 1 sq foot
areas along with depositing some glue-like material. I have been
able to remove the material deposits with acetone and lots of elbow
grease and even more cussing. But the aluminum appears to be
permanently stained a lite brown color. It will be painted so I
don’t really care about the cosmetics but am concerned if I have
compromised the integrity of the aluminum. I have put a thick layer
of paste wax over the area to try to limit any further corrosion. I
wish I could post pix and that’s something I’ll learn to do soon but
in the meantime any thoughts are appreciated.
A: If the aluminum
surface is still smooth and shinny and the only visible change is
coloration/staining, I don't think you will have any problems.
Just make sure you get rid of every bit of the wax before painting
or you'll have fisheye problems. It's really hard to clean
contaminants like wax & oil out from around rivet heads when
prepping for paint.
Another Hole in The Rib Question

Guess Who is Going to OSH Next Week for a Big 'O Award
building an RV-4, Rob drew on his background in electrical
engineering to design and build his own engine monitor. He thought
he’d just make one for himself, but then a friend wanted one, then a
local avionics shop wanted one, and suddenly, Rob had a new
business. Advanced Flight Systems was born, focused on manufacturing
and selling the ACS 2002.
The monitor evolved from the first color screen available to the
experimental market to an EFIS with synthetic vision, attitude, AOA,
mapping, weather, traffic, and integration and connectivity with
other outside components. After joining forces with Dynon Avionics
in 2013, Rob was able to focus on his latest innovation, which is
designing and building complete plug-and-play panels using a central
control module that eliminates most of the wiring involved in
building an airplane.
What started at the dining room table in the late 1990s is now a
company with 10 employees and a 7,500-square-foot facility in Canby,
Oregon, and customers throughout the world. He is respected by his
employees, industry peers, and customers alike."

While match drilling the W-707 doubler

MGL V16 transceiver about to be released
The V6 and V10 radios where based on an
original MGL design many years ago that was never put into
production. Subsequently another South African company called South
West electronics took on the original hardware design and packaged
it into the V10 and then V6 formats. MGL itself provided the
firmware. These radios where then sold under the MGL brand name.
This arrangement has come to an end a year ago. The V6 is still
available through MGL Avionics in the USA but is no longer a branded
MGL product. Ownership of the IP has passed to South West
Thus a year ago MGL started the design process of a new radio to be
called the V16 - this time a true MGL product, fully designed and
manufactured in house.
The first production batch of the V16 is now ready to be released.
Here are the bullet points:
1) 10W+ TX power, very high efficiency, low DC power needs.
2) Built in SWR meter for antenna checks and power measurents
3) World's first fully digital airband receiver, easily surpassing
all required certification requirements for any receiver class.
Based on direct conversion I/Q zero IF technology. No spurious
receptions, excellent sensitivity, selectivity and large signal
handling abilities. Very high audio quality, zero distortion.
8.33Khz and 25Khz channel spacing with full support for offset
carrier operations in each.
4) Impulse noise detection and removal (removes typical ignition
noise and many other noise sources from received signal).
5) Recording and simple playback of received transmissions.
6) Two circuit intercom, fully digital 24bits. Newly developed noise
gating combines the best features of a traditional VOX and MGL's
Vogad into a single, simple to use and highly effective system.
7) Independent RX and intercom volume controls.
8) Split module design. Transceiver body can be used stand alone
with any MGL iEFIS G3 or combined with either a 2.14" head or a
3.1/8" head. Both heads are color and the larger one has a touch
screen as well. You can also use multiple heads and connect to EFIS
at the same time.
9) With any of the two heads, the V16 is protocol compatible with
industry standard protocols (selectable in head setup). Note that
NAV/COM protocol compatibility requires the MGL N16 navigation
receiver which should be available by February.
10) Lowest cost of any COM transceiver available, combined with N16
lowest cost of any NAV/COM available.

Another Take on Oil Door Hidden Hinge
Initially, I was using a formed sheet-metal
hidden hinge for my oil door. Similar to a number of products
available from experimental AC suppliers. I didn't really like this
solution. I thought there was too much flex in the hinge system to
work with my push-button camloc latch. I was able to pop the door
open with light outward force since the hinge would flex.
I designed a new hinge that works much better. I am probably not the
first to make it this way, but haven't seen it posted here. It works
very well. The final version incorporates a spring to hold the door
open. Total weight is only slightly more than the Vans setup, most
of that is from the latch.
Note: I made my oil door from aluminum. I had already drilled it for
the formed hidden hinge, that is why there are extra holes. In the
end, I filled those open holes with rivets.
The hinge pivot could also just be a solid
shaft. I machined bushing on my lathe. The bolts are fully torqued,
the bushings have a step machined in to set the end-play. There is
very little play (less than a piano hinge) to allow fretting of the
Normally, on the pink cow at least, the area where I have the hinge
mounted is a low spot between the cowl honeycomb core and the oil
door flange. I filled this area with epoxy/flox for the hinge mount.
Forward Stick Authority on takeoff RV-6
I finished my tailwheel endorsement in a Super Cub two weeks ago.
So now that I have 6.5 hours of TW time, I am obviously an expert.
In the cub, the takeoff procedure was stick full aft for two
seconds, and then take 3-4 second to go full forward on the stick
and hold it there. The tail would raise, but would not raise further
than approximately level flight.
I was surprised that it really was generally not possible to raise
the tail too far and have a prop strike.
My question in the RV-6 is this: if I go full forward on the stick
in the RV-6 and hold, will the tail continue to rise as speed builds
and eventually cause a prop strike?
Or is the design of the RV-6 such that full forward stick on a
normal takeoff (no gusting winds), will not cause a prop strike?

2) When do we install them?
Propeller blast etiquette……
It is always frustrating when this happens but even more so when done
by an RV owner/pilot. I always have hopes that they are above
average when compared to the general pilot population but time and
time again I find that is not the case.
An RV-10 owner (I don't know who so they can fully remain anonymous)
just left Van's Aircraft in what from a distance looked like a
beautifully built airplane after a short visit.
If you have ever visited you know that there is a pretty good sized
paved ramp area in front of the hangar for aircraft parking. The
typical parking method is to pull onto the ramp facing towards the
hangar (you will find all of the company airplanes positioned this
way if they are outside).
When any airplane leaves, it can turn 90 degrees, taxi down the ramp
a short distance and then make the big turn to taxi away from the
ramp towards the runway.
What happened today (third time this week actually), and is far too
common, is the RV-10 pilot used high power to do a 180 degree pivot
turn (they were the only airplane parked on the ramp) which left
their tail only about 60 from the open front of the hangar.
I am getting tired of cleaning out the hangar so often.....
Over the years, I have seen other airplanes sand blasted, canopys
blown shut (and damaged), control surfaces damaged, and yes, hangars
filled with CR%p.....
All by other pilots that failed to think and often times taxied away
totally oblivious regarding what they had done (as likely is the
case in this instance).
Good reminder lesson for all of us.....
When operating the engine on the ground (whether taxiing, doing a
run-up, or whatever) please keep in mind where your airplane is
pointed and what is behind you.
Tube-like positive mold in high density PU
I’m trying to fabricate a tube-like glass fiber duct between a NACA
inlet and an fresh air vent. I thought the most straight forward
method would be to use a positive mold of high density PU, wrap it
with glass fiber and after curing, dissolve the PU with acetone.
I haven't been on this forum in a while mostly due to life
situation. I have a RV-8 wing and tail kit, done up to the pre-close
inspection. I started building my plane in London Ontario. Then work
had me hopping all over Manitoba and Ontario for a couple years, and
now I am finally settling down in Thunder Bay. My problem is the
very small general aviation community here. There are a couple 172s,
Cherokees and the like, but that's it. Certainly no active home-buil
community like I was used to in London.
My wife and I are buying a house with a nice 1.5 car garage. There
is certantly room to move the project up here, buy the fuselage kit
and continue building. She is also supportive of this project.
However, without a general aviation friendly airport and no builder
community, it becomes very difficult endeavour and really isn't
within my means. For example, the airport authority recommended I
build my own hangar as they said there aren't any available.
I am really hoping there is someone in the area who can point me in
a direction that makes this realistic and feasible. A building
partner would be great! If I can't make this come together, I will
unfortunately be forced to sell the project.

New AF-5000 Pilots Guide Manual ...Rob Hickman
We have posted an updated version of the AF-5000 Pilots Guide. We

Canadian customers RV-10 so that we can validate the Canada XM Weather. We
plan on releasing the V15 software for beta testing next week and should
have the production release in the next few weeks.
Version 14 had a lot of new software to support a very specialized project
that we developed an EFIS for. Since we also upgraded the Skyview network
software in the release to the latest HDX V15 software it seemed to make
sense to keep the versions the same.
Pneumatic Carb Sync
Syncing the carbs is one of the most satisfying aspects of the annual
condition inspection — or the most frustrating.
When I took my Repairman course the instructor showed us how to use
the CarbMate tool to pneumatically synchronize the carbs. That
looked pretty cool, so I bought a CarbMate. Bad decision. The
fittings that it came with were US automotive dimensions and the
Rotax carb tubing is metric. I had to make adapters. After working
with it I found the moving LED lights hard to interpret and
confusing and had to school myself each time I used the tool to
relearn how it worked. Syncing took a long time. The CarbMate went
on the auction site as a motorcycle sync tool. Hopefully another
Rotax mechanic didn’t buy it.
Over the past 20 hours or so I have noticed that for the first 45 min to
1st hour of flight I have a slight vibration at most any RPM, which
previously was not noticeable. Over a period of 45 min to hour of cruise
flight, the vibration continuously gets less and less until it is not longer
noticeable. This is not a lot of vibration, but enough that my wife noticed
it. It's enough to notice in the glare shield, and on the stick. It is
consistently repeatable and can be duplicated by letting the aircraft sit
for several hours. Flying again for 45 minutes fixes the vibration. I can
shut off each ignition in flight and not make any change to the vibration,
so it's not an ignition issue.

I just concluded my annual inspection and did the following, with no change
in the symptoms:
•Reamed all 4 exhaust guides per Lycoming Service Instruction 1425
•Removed left mag inspected, replaced points and cam, set e-gap etc. and
•Verified timing of Electroaire electronic ignition
•Serviced, gapped and measured resistance of all plugs
•Measured resistance of all plug wires
When I review my Saavy data online it looks absolutely perfect, I can tell
the engine is developing full HP in that my cruise speeds have not changed.
My fuel flows and leaning have not changed. My CHT spreads are the same as
prior spread a year ago as are the EGT spreads. I bore scoped the cylinders.
The only remaining idea that I have is that the prop grease seal has been
compromised and grease is getting into the center of the hub and settling
when the plane is sitting idle. When the prop starts spinning and the hub
gets filled with warm oil, the grease redistributes itself and the vibration
So as I write this I am about to leave to drive Hartzell this morning to
have them tear down the prop. and hoping that is the issue. Any other ideas
from the VAF brain trust are appreciated.

As most of you know, 52F now has an amazing new runway.
Come try it (cheapest fuel in the area
here). With the runway now done, the P.O.A. is tackling the run down lighting system that is
in real need of some loving up. There are (120) lights currently on
airport property, and as they burn out are being replaced with more
efficient (and bright) LEDs.
owners back in the day didn't have input on how the lights were done.
Much of the existing wire is NOT underground Romex and the Scotch Locks are
not in waterproof junction boxes -
you can imagine the voltage leakage after decades of sitting in damp soil
Four lights are inop due to this - we're

RV-4 panel upgrade
RV-4 panel upgrade
It's taken me a few days to gain emotional
distance enough to deal with a huge setback in my project. I had
bought an aircraft lift, which seemed like a great assist, both
letting me move both aircraft into the hangar and also positioning
the aircraft to work at a convenient height. I had contacted the
lift manufacturer for maintenance info (it was purchased from the
estate of a pilot here in Flagstaff) and they recommended
retro-fitting the jack-screw mechanism with a chain hoist. Well, I
should have listened because the lift failed on the 16th while I was
lowering it to work on the project. Fortunately, that meant that the
-6A was safely outside the hangar and I was not under it because it
is operated from the side.
I would estimate the weight of the lift yoke (which the fuselage on
gear was strapped to) and the fuselage to be close to 3000 lbs. It
did not free-fall due to the geometry of the lift but I came down
very fast from between 3 and 4 feet, to a sudden stop on the hangar
floor. Due to the added weight and the fact that the wings weren't
on (no aerodynamic drag like you'd find in a stall landing at that
height), I'm sure it's like stalling in from a greater height.
So, the good news first. You'd definitely survive such an incident.
I'm not sure what the wing attachments would look like but the
fuselage structure was largely intact. Now the bad news. On closer
inspection, the side skins were wrinkled low behind the main spar
carry through and the bottom skins were wrinkled behind the mains
all the way across. The pictures don't show it too well. The was
also slight wrinkling at the panel attachments to the side skin.
More good news: I won't know for sure until I disassemble everything
but it looks like all the rest of the structure is Ok. The floor and
seat pans are fine and I'm hoping the ribs underneath are the same
(though I will, of course, check. All lateral forms are fine. I
expected to find some stress around the baggage door, which was
open, but found none. The entire tail cone, including empennage
attachments, show no signs of stress. And likewise on the firewall,
which had the mount and engine. The gear also checks out.

After three years of hand-flying IFR, I added a Trutrack autopilot.
If I had to do it over, I would have added that much sooner! I had a

To reduce the “get thereitis” I always allowed sufficient time on a
front end commute to be able to land enroute, rent a car and still
make it to work.
The RV was a full hour faster door to door than total commute time

Seems like we read an awful lot about
alternator issues on this forum. I’m wondering why we seem to suffer
disproportionately with these issues compared to the rest of the
motorsports/industrial world? After all, when was the last time you
had the alternator in your car go rogue and fry the computer? There
has been a lot of attention given to OV crowbar protection, fuses,
alternator shutdown schemes, etc, but shouldn’t we also focus on
what can we do to minimize the frequency of failure in the first
I’m no expert, but it seems we are turning these units much higher
than needed. Reading suggests that the output curve flattens out at
around 6000 RPM, so if we take the typical 3.25 overdrive ratio of

alternator at almost 8800 RPM at takeoff (and maybe cruise for you
Very slow oil warm-up?
Q: I have recently acquired an RV-8
with an angle-valve IO-360. At lower OATs (below 60°F?), I find it
takes inordinately long to get the oil temp up. I prefer to
get up to 150-160°F, especially when doing formation TOs that
require lots of throttle jockeying. At those temps, I'm seeing
90-100 PSI at 2700 RPM. Temp regulation in flight appears to be
normal and cruise numbers for temp and pressure are good.
thought I understood the operation of the Vernatherm
valve. But to more expert guys - Is there a failure mode of the
Vernatherm that would not bypass the cooler at lower temps,
ie. always have the oil cooler in the circuit? (At home base, I
know I can install and use a sump heater, but sometimes when out X/C
there is no power available.)
The vernatherm valve system always provides oil to the oil cooler.
When oil temp is low, the valve opens allowing a bypass line around
the oil cooler in addition to some oil still going to the cooler. It
does not stop flow to the cooler, just reduces it.
I installed a butterfly valve to control cooling air to the oil
coolers on both the RV-8A and RV-10. Even at OATs in the 70s I need
to close down the oil cooler air a little to keep oil temp at 180 or
so in cruise.
A: I have 1/3 of
my cooler blocked off in the summer to get the oil temp > 180, which
is should be your minimum target temp.
Temps here the other day were in the low 70s and my oil temp only
made it to about 175 in a 30 minute flight. Planning to install a
slider mechanism for a more permanent solution that I can control
from the cockpit.
That pressure is a bit on the high side and can be adjusted, which
might also reduce the amount of oil going through the cooler when
the vernatherm is (mostly) closed.
Oil cold: Flow is through both the cooler and a cooler bypass
port, in parallel.
Oil hot: Flow is through the cooler alone. The tip of the vernatherm
closes the bypass port.

Shop Regrets ...Bill Boyd chimes into Tdeman's thread
Working in the kitchen - good job! I hope
that continues to work well for you!
Our biggest regret rebuilding after the house fire 2 years ago is
not putting the shop "off-campus" out in the yard. I can't run any
tools or even accidentally drop a wrench without waking the wife
sleeping overhead in our first-floor master. And the fiberglass dust
and aluminum shavings that get tracked upstairs despite the doormat
and the carpeted stairs drives us both crazy - mostly her. I make a
lot of runs up and down the stairs in a typical work-session
evening, so taking my shoes off as she suggests would gobble up a
lot of work time, which as for many of us, must be carefully
regulated and apportioned so as not to neglect wife and children.
Despite the downside to a backyard shop (long walk in the dark, need
to run power and water, the big air conditioned and heated basement
was already there needing only interior finish) I do wish I had done
it - my useable work hours would be so much greater. There was the
psychological perception that being right downstairs was not as for
removed from the family hearth when everyone else wanted to veg and
watch TV, but that's an empty premise in retrospect.
In-Flight Smoke Incident Report ...Bill Palmer

On February 8, 2017, the incident aircraft (an RV-8A purchased by
the pilot from its original builder), departed Sedona Airport (KSEZ)
on a return flight to Phoenix Deer Valley Airport (KDVT) with two
pilots on board. Total time on the aircraft/engine was 880 hours
since new. The pilot had owned the RV-8A for over 6 years and flown
the aircraft over 320 hours without incident.
At the time of this incident, the aircraft had flown a total 6
flights and 2.7 hours since undergoing an instrument panel upgrade.
A Dynon Skyview HDX system was installed in place of the standard
“Six Pack” of instruments and Van’s standard engine gages. In
addition to the Dynon HDX system, to save weight, an EarthX ETX-680
Lithium-Iron-Phosphate (LiFePO4), battery was installed in place of
the standard lead-acid battery. Both pilot (front cockpit) and
copilot (rear cockpit) were experienced, current ATP pilots.
Approximately 16 minutes after takeoff, while accomplishing an
in-flight compass calibration test, consisting of 360-degree turns
at 7,500’ MSL (3,000’ AGL), both pilots noted a brief acrid smell
(for about 2 seconds). Engine/electrical indications were reviewed,
and no anomalies were noted. Specifically, volt and amp readings
were observed to be within the normal range – 14.3 volts and 14
Approximately 18 minutes after takeoff a climb was initiated from
7500' to 9500' MSL along with a turn to the southwest toward less
challenging terrain; just in case an emergency landing was required.
Approximately 1 minute later (19 minutes after takeoff), the voltage
and amperage indications started to increase rapidly and fluctuate
(voltage fluctuated between 19 and 25 volts, and amperage fluctuated
between 40 and 44 amps). In addition, the electrically-powered fuel
quantity indicator failed. Because the pilot thought he was
experiencing a component electrical problem behind the panel, all
electrical component switches were turned off; however, the
Alternator/Battery Master Switch was inadvertently left on. The
pilot acknowledges that he should have confirmed that the master
switch was turned off when he first observed the high voltage and
amperage fluctuations, however, he was focused on a
"behind-the-panel" component failure; not an aircraft electrical
power system failure. (Note: the alternator's main 35-amp breaker
had not tripped).
Approximately 4 minutes later, while maneuvering the aircraft to an
area where an off-field landing could be attempted, a strong
“solvent type” odor was detected, and an immediate descent was
initiated. Several seconds after initiating the descent, smoke
entered the cockpit from behind and below the instrument panel. The
source of the smoke confirmed to the pilot that he probably did have
a behind-the-panel component failure. With the appearance of the
smoke, a high-speed emergency descent was initiated via a Split-S
maneuver. The copilot suggested opening the canopy, however, lacking
any knowledge as to the ability to maintain structural integrity of
the aircraft when opening the canopy inflight, the pilot initially
elected not to open it. As the smoke intensified, visibility in the
front cockpit was reduced to near zero, and it became very difficult
for the pilot to breathe. The copilot in the rear cockpit had
better, but limited, visibility and some fresh air from the rear
air-vent sourced from the underside of the right wing. Having no
other option, the pilot transferred aircraft control to the copilot,
and the decision was made to open the canopy.
The pilot then attempted to open the canopy with one hand, but was
initially unsuccessful. The canopy would not easily open as it
normally does during ground operations. Using both hands on the
canopy handle and much greater force than normal, the canopy slid
aft approximately two feet. As fresh air flowed around the
windshield, most of the smoke vented out of the cockpit via the
canopy bottom skirt. Although smoke was still entering the lower
portion of the cockpit, the pilot had recovered visibility and the
ability to breathe. The pilot did not detect any heat or fire, and
the copilot found that he could easily hold the canopy in the
partially open position. Therefore, aircraft control was transferred
back to the pilot while the copilot held the canopy to prevent it
from sliding to the rear stop.
The pilot originally intended to land on a nearby stretch of
interstate highway located approximately 5 miles ahead; however, the
copilot observed a street pattern at 3 o'clock and less than a mile.
The pilot circled to slow, and successfully landed on an uphill
residential street, without any related damage to the RV-8A. The
airplane was stopped, and the engine was shut-down approximately 27
minutes after takeoff and 3-to-4 minutes after the emergency descent
was initiated. The descent covered approximately 5500 feet, and the
descent rate averaged approximately 1600 feet per minute with peak
descent in the neighborhood of 3000 feet per minute. TAS (true
airspeed) during the emergency decent was recorded as high as 194
knots; with the canopy open.
After landing, smoke continued to enter the cockpit from behind the
instrument panel. Halon was discharged underneath the panel, and the
crew exited the aircraft. The forward baggage compartment was
opened, the instrument (rear-access) panel was removed, and halon
applied to the back of the instrument panel. At this point it was
discovered that the source of the smoke was from the battery
compartment located directly below the front baggage compartment, on
the right side of the aircraft. This area was repurposed by the
original builder as a battery compartment, complete with an access
panel on top. The battery compartment access panel was removed, and
the remaining halon applied directly to the battery. After the halon
bottle was depleted, dirt from the roadside was used to completely
extinguish the smoldering battery.
Note: No radio transmissions were made during this incident, since
the radios were turned off to protect them.
The pilot was treated for smoke inhalation at a local hospital and
has fully recovered. The pilot did not suffer from any burns or
additional physical harm. The copilot did not suffer any physical
harm. The FAA and NTSB were notified and classified this mishap as
an unreported “incident”, since there were no serious injuries or
structural damage to this experimental aircraft. The RV-8A was
dismantled and transported to a repair facility. Subsequently, the
RV-8A has successfully returned to flight with no further problems.
The battery involved was an EarthX Model ETX-680
Lithium-Iron-Phosphate aviation battery with a dual-redundant
Battery Management System (BMS). The EarthX battery was the
aircraft’s sole main battery. The EarthX battery was hard-mounted in
the RV-8A’s lower forward baggage compartment in place of a Concorde
lead-acid aircraft battery; in the same location.
There is no record or evidence of an EarthX battery physical
installation problem; however, EarthX’s installation manual says:
“Installation of the battery in the cockpit is not recommended,
unless the battery is properly vented over-board.” Technically, the
battery was not mounted in the cockpit, but it was mounted in an
enclosed compartment internal to the fuselage, aft of the firewall,
and adjacent to the pilot’s right foot and leg. The battery
compartment had a top cover, but unfortunately did not include an
The EarthX battery’s remote, discreet warning output (LED panel
light or EFIS input) was not installed as recommended by EarthX.
Since this installation seemed to be optional, the pilot/owner
delayed the installation in favor of testing his new Dynon HDX
system. The Dynon Skyview HDX EFIS was equipped with its own
internal backup battery plus an advanced aircraft/engine
instrumentation system which continued to record all flight, engine,
and electrical data from takeoff until landing.
The highest recorded peak voltage was 29.1 volts although it is very
likely that the voltage greatly exceeded 30 volts as there was a
two-second voltage data drop-out at that time. There was also an
initial, half-second voltage data drop-out about 4 minutes earlier
as the recorded voltage increased above 20 volts and fluctuated. The
highest recorded peak amperage was 44.8 amps. The Dynon data shows
that a simultaneous, average voltage / amperage level of 21 volts /
42 amps (approximately 880 watts) was applied to the aircraft
electrical bus (and EarthX battery) for a total of approximately 5
minutes although all other components connected to the bus were
switched off (disconnected from the aircraft electrical bus) as soon
as the fluctuating excessive voltage (19 to 25 volts) and high
amperage (40 to 45 amps) readings were initially observed. The
master was left on, because the pilot was focused on a panel
component failure; not an aircraft electrical power system failure.
Unfortunately, the aircraft had no automatic overvoltage protection
circuit as “strongly recommended” by EarthX's installation manual
(at the time of installation). When the RV-8A was purchased, the new
pilot/owner was unaware that the aircraft was equipped with an
automotive alternator/regulator with no overvoltage protection.
Also, lacking a detailed aircraft electrical system schematic, the
pilot/owner was unaware that the aircraft electrical system had no
inherent, built-in overvoltage protection. Also, the installation of
overvoltage protection seemed to be optional at the time (“strongly
recommended”), so the pilot/owner did not inspect the
alternator/regulator and aircraft electrical system to see if
overvoltage protection was installed.
After the incident, the automobile-style alternator, a 35-amp-rated
Bosch AL204X with integrated regulator/rectifier, was removed for
bench testing and found to be non-functional. There was no output
from the alternator. The Dynon data shows the alternator output
starting to drop at 24 minutes after takeoff and the alternator
output failing completely 1 minute later (2 minutes before landing).
Please note that this bench test was only a functional test. There
was no additional testing or detailed failure analysis to pinpoint
the cause of alternator (regulator) failure. Also, there was no
attempt to duplicate the high voltage and amperage recorded
in-flight. The alternator was simply “dead.”
The alternator output breaker was rated at 35 amps, but did not trip
during the incident despite the Dynon-recorded high voltage (21+)
and amperage (42+) levels. The breaker was tested after the incident
and tripped at less than 36 amps with 14.3 volts. After developing
an aircraft electrical system schematic and reviewing it (including
the Dynon shunt location in the alternator output between the
alternator and the 35-amp breaker), the authors have no definitive
explanation relative to why the breaker did not automatically trip
in-flight and thus save the battery. There are several possible
answers, but there is no information clearly pointing to one answer.
The authors have decided not to pursue a more detailed analysis.
The damaged EarthX battery and the Dynon instrumentation data were
sent to EarthX for analysis. Also, the authors subsequently
communicated with EarthX to determine what EarthX discovered about
the battery and the incident. Based on the Dynon data and
inspection/analysis of the battery, EarthX concluded:
The battery was forced into thermal runaway for two reasons:
(1) The alternator/regulator failed resulting in the application of
sustained, excessive voltage and current to the battery which was
above the rated limits of protection for the battery’s Battery
Management System (BMS). Battery inspection clearly showed physical
evidence of extremely high voltage being applied to the battery
which was above the rated limits of the BMS.
Authors’ Note: According to the Dynon data, the power applied to the
battery was sustained at about 880 watts; peaking at well over a
kilowatt (1,240 watts).
(2) The pilot/owner should have shut-off the master switch as soon
as the fluctuating, excessive voltages and amperages were observed.
To quote EarthX:
“The aircraft voltage regulator failed and the battery was subjected
to voltage greater than 20V charging with high amps for more than 7
minutes which caused the cells to reach thermal run-away. At a
couple of points, the voltage spiked so high that the Dynon didn't
record. Based on feedback from Dynon technical group, the voltage
must have been above 30V. Our Battery management system indicated
that the voltage exceeded 70V.”
“An over-voltage protection circuit in the alternator regulator
would have shut-down the alternator within 100ms in the event the
voltage exceeded 16V, but this equipment was not installed on your
Authors’ Note: THE EARTHX BATTERY DID NOT CATCH FIRE. Although the
battery over-heated in thermal runaway, the heat given off during
thermal runaway event was not sufficient enough to burn the pilot’s
leg or foot through the thin aluminum battery compartment wall. The
pilot does not recall detecting excessive heat from the battery
compartment. The main effect of the thermal runaway event was the
eventual emission of smoke as the battery overheated. The smoke was
emitted though wiring grommets in the battery compartment wall as
well as small gaps at the edges of the battery compartment. Smoke
emission would be expected from any battery, lithium or lead-acid,
experiencing a thermal runaway event.
PROBABLE CAUSE WITH RECOMMENDATIONS
NOTE: This PROBABLE CAUSE is SPECULATION . . . a definitive cause of
this incident based on detailed technical analysis is UNKNOWN.
PROBABLE CAUSE (Automotive Alternator Regulator Failure):
The most likely probable cause of this in-flight smoke incident is
alternator voltage regulator failure and the resultant direct
application of extreme overvoltage and excessive amperage to the
EarthX battery which was above the highest levels of the stated,
rated design of the Battery Management System (BMS) protection and,
thus, the battery was forced into thermal runaway; heating up and
eventually emitting smoke as it failed.
RECOMMENDATIONS (CORRECTIVE ACTIONS):
1. Install an overvoltage protection system for each aircraft
alternator, generator, or dynamo. The authors note that EarthX has
amended their operation and installation manual to “require”
overvoltage protection circuitry for alternators exceeding 20 amps
of output. The authors agree that overvoltage protection is
2. Install the battery’s discreet warning output to either a panel
LED or to an EFIS as shown in EarthX’s manual. This installation
should also be viewed as required.
3. Install cockpit and/or battery ventilation to expel smoke
overboard. The EarthX manual states: “Installation of the battery in
the cockpit is not recommended, unless the battery is properly
vented over-board.” Installation of overboard ventilation should be
viewed as required.
4. Each EarthX battery and its integrated BMS are extensively tested
at the factory before shipment, but field-testing of BMS
functionality is not recommended. The authors’ understanding from
EarthX is that the BMS’ overvoltage protection and charging current
inhibiting features cannot be successfully field-tested without
risking some residual damage to the battery. Thus, installation of
overvoltage protection circuitry and the discreet warning output
(LED or EFIS) is very important in lieu of being able to safely
field-test and measure BMS functionality.
5. If it can be done safely, the aircraft’s overvoltage protection
system(s) should be tested after initial installation in the
aircraft and then periodically. A sustained overvoltage beyond 16
volts should cause the overvoltage protection system to disconnect
the source (alternator) from the aircraft electrical system and
6. To protect against smoke emission in the cockpit, fire detection
and suppression equipment should be installed if a battery (lithium
or lead-acid) is mounted aft of the firewall. This equipment should
be readily visible and accessible. For enclosed units like a
battery, an injection port would be needed to apply the retardant.
From the standpoint of a battery thermal runaway event, the
application of fire retardant is most important for the prevention
of smoke emission.
7. IMPORTANT: For Non-Builders Purchasing Experimental Aircraft:
Make absolutely sure that you have a detailed, current schematic of
the aircraft’s electrical system. Carefully analyze the schematic
and understand what it means in terms of aircraft electrical system
operation, design, redundancy, and safety. Physically inspect the
aircraft’s alternator/generating system(s) and aircraft electrical
system to confirm that overvoltage protection is installed. Also, if
the battery manufacturer supplies a discreet warning output as
EarthX does, definitely install it prior to any flight operations.
In summary, it is important to realize that if you purchase an
experimental aircraft built or modified by someone else, you
effectively become the aircraft’s engineer and design decision
maker; not just its pilot, owner, and maintainer. Buying an
experimental aircraft is not like buying an FAA-certified aircraft
whose design/build is formally reviewed, tested, and controlled. For
an experimental aircraft, you must make sure that the aircraft’s
systems are acceptable to you based on your own design, cost, and
flight risk decisions; not the builder’s or modifier’s. If you do
not feel confident in your ability to properly assess an
experimental aircraft’s design, definitely find a respected,
experienced aircraft builder to help you determine the aircraft’s
design, build condition, and relative level of safety. DO NOT TAKE
ANYTHING FOR GRANTED or fail to analyze the aircraft’s build quality
and systems from a safety standpoint! In other words:
FLY KNOWLEDGEABLE AND FLY SAFE!

Video Status Report ...kiljoy RV-14
So I finally found time to make headway on
the left flap. After a couple of days of deburring duty I found
myself ready to prime and dimple. Everything there went normal. I
did have to do a few pop rivet close quarters dimples in the front
of the leading edge skin for each rib. Doesn't matter much they all
get pop riveted in the end anyways.
The biggest challenge with the final construction has been having
the ribs be one piece attached to the spar first vs the zipper
method of the rudder or the stiffener design of the ailerons. With
both skins in place you need to put your hand between the skins with
a small bucking bar and buck the rivets for the leading
edge/spar/bottom skin holes. I have a 1x1x2 tungsten bucking bar
that thankfully fit but where the ribs are you have to get your bar
in there and the angle of the rib doesn't flex like the skins do in
between the ribs so you need an even smaller face'd bar. That way it
will buck all the way in without being stopped short by the rib or
the skin and doesn't run the risk of causing a dent in the skins as

180* descending half circle to the flare with minimal power changes.
Right as all three wheels touched I dumped the flaps and rolled to
my exit at the Charlie taxiway, a short 958' from the displaced

Removing plastic from under rivet

visible around the rivet.
The only way to remove it from under a rivet is to first remove the
When rivets are installed properly, they fit very tight against the
bottom of the dimple or countersink. This would make it impossible
to remove the plastic. Even if you could, you would then have a

Filter shrank - in three hours
I had 25H TT on my filter before needing to do my condition
inspection. I removed the filter which fit just fine, it did not
snap off or anything odd. It sat for a couple hours, still fine. I
washed it (K&N filter wash) , set it out to dry (breezy sunny day
after a gentle air blow off). Was wrapping up and pulling stuff in
to find one side of the filter had shrunk significantly,
diametrically, over three hours of drying time. It looks like a
trunchated cone now. I can't say if just letting it sit would have
caused the same shrinkage, but I'm suspicious of the washing
process. I'll go to blow-off/shop vac/re-oil for regular condition
inspections now, and a periodic replacement (3 years? 5? Depends on
degradation or deformation) rather than washing.

Finishing up RV-10 Tailcone - Questions Antennas, Magnetometers and
riveting top skins
Well, it's time to ask for some advice from "the collective" as
I'm basically trying to decide my next steps. (Regardless of the
advice, I realize I am responsible for my own decisions )
Currently I have finished the tailcone (Section 10), but have not
riveted either of the two top skins on yet. I had a local EAA Tech
Counselor visit that suggested that I determine what antennas I want
to install (including magnetometers) and to NOT rivet on the top
skin (F-1075) until much later.
While I can see the benefit of maintaining mostly full access to the
tailcone, has anyone else done this that can provide some advice?
I'm leaning towards riveting it on before I attach the tail feathers
for better rigidity (and following the plans).
My other questions are regarding antenna choices and mounting
locations. All along I have wanted to get a G3X Touch system,
however I didn't plan to purchase any avionics or antennas until I
basically done with the aircraft. Looking at some other build-logs
(Looking at you rdamazio), it seems that I really am not thinking
far enough ahead in my build!
I'm currently plowing through the G3X Touch install manuals and
trying to spec out what I would purchase today if I had to pull the
trigger and I feel like I'm missing something regarding the GMU-22
and GMU-11. I see quite a few posts of RV pilots using the GMU-22,
however based on the current install manual, the GMU-11 is
recommended unless my RV-10 will do over 300Kts. Is the GMU-11 just
a newer option or is there a reason to go with the GMU-22?
For antennas, and things like ELT's, when is it recommended to
purchase / install? I guess there is nothing wrong with holding off
to install this stuff much later in the build. Worst case is I have
to stuff myself in the tailcone to mount these items once everything
is buttoned up?

As I taxied onto the ramp at Beach, I saw a man in his seventies
standing by his car. He was wearing a baseball cap, and a pair of
suspenders were pulled over a flannel shirt and holding up a pair of
blue jeans. He walked gingerly over to the Dove as I swung the tail
around and shut down.
When I opened the canopy, he asked if I were going to tie down for
the night. I told him that I did not know. I got out and introduced
myself. He said that his name was Boyd. I told Boyd about the 40-day
and 40-night flying mission I was on, and he took me over to a

Finally happened ...Scott McDaniels
It's been a bit over 11 years ago that I completed the rebuild of
the damaged RV-6A project that I purchased, and got it flying again.

anyway) was finally painting it just over two years ago.

(as it is known) was previously too ugly
to even bother with photos and since painting it the opportunity
just hadn't come up, but it finally happened this week.

Flight restrictions removed ...Tom Martin RV-14
We had a 8 day period of beautiful weather at the beginning of
October and I was able to get my 25 hours flown off in 8 action
packed days. Today after submitting the paperwork yesterday I got my
final flight permit and the plane is ready for some adventures.
Nearing the end of the flight test period I was getting really
comfortable with the airplane. Approaching the airport from the
north I joined a mid field circuit at 1000 agl and immediately
chopped power. At the time airspeed was about 100knots. A gradual
curving approach easily had me make the field about 1/3 of the way
down the runway, as planned. The RV14 is not a glider but it handled
the situation with ease and it is a comfort to know that you can
make the field if you are in a normal circuit. My rocket would have
just made the field, maybe, depending on winds.

believe it will give you an feeling for the landing.
Two RV-10 Questions ...Miguel
1) was going through plans and an op-38 section fell out. No clue
where I had it. Brought a question to mind about the timing of
optional plans and kits and when to do them. Any list out there for
a slow builder. I know the elec aileron trim isn't too crucial for
timing but thought I'd ask for the other ones. I plan to order the
full plans soon to be able to read ahead and get a much better idea
of what I happening after I finish the wing kit.
2) was talking to a friend about being extra careful working with
the main spar assemblies. What do one of those bubbas cost? I found
a post mentioning the central spar that is part of the fuselage at
$1400, but can't find anything on the wing spars here or on the Vans
A: When you buy the full set of plans on the memory stick
(why they don't have a secure download location is beyond me) it
will include all the optional plans as well. Well worth the 10 +
shipping they charge for it. I have made mental notes and a few
written notes about certain ones. Such as OP-48 with regards to the
AHRS bracket and not to rivet those rivets in the tailcone as I will
simply have to remove them later.
As for the price of the spars, No idea. You are correct in the 1400
for the center section. I would be willing to guess somewhere in the
neighborhood of 2500 each. The total wing kit is just over 10,000 so
half is comprised of the spars. Makes sense to me as the other
components are not that expensive. You can look up almost every part
except for those using this "list".

tube-like and concentrated coming through them.
Melting Wingtip Lens....time for LEDs?

Firesleeve on Hose
Wondering if this rubber? coated stainless fuel line needs to be
firesleeved or is this good to go as is?
So a big thank you to all who chimed in on my question! I learned
several things from your replies. Among them was the obvious that my
sawtooth edged holes really were a problem....
I also learned there are some good options available for me to try
different bits. I also heard that my Avery tool with a three flute
cutter should give me good results if I use it properly and possibly
“break in” my cutter or replace it, if required. I also learned that
I should try going much slower.
Based on all of this advice I decided that I would start by trying
to make my existing tool work and then move on to trying replacement
cutters. I very carefully ran the top edges of my cutter across my
3M cut and polish wheel to try to clean up the edge. This seems to
have done the trick. After a gentle brush across the wheel and
spinning very slowly I get this:

Ok. I'm finally, finally pulling the trigger. I've been lurking
for years, and have settled on an RV-8 build. My chief delay, or
concern, has been my availability at home - I spend about 70% of my
time on business travel. But during the 3-4 years I've been thinking
about this, and I know this might be shocking: I haven't gotten any
I'd welcome any comments on my plan. Are there any significant
gotchas in this sequence?
1) launch the empennage build working with Jay Pratt. I'd like to
get off on the right foot and learn some good techniques.
2) get the fuselage in and start building. To me this will be the
most challenging and time-consuming by far. I plan to do a
showplanes fastback kit, and a few other things in the interior. I
want to complete fuse/interior/panel/canopy, aside from any
wing-related connections and setup, before finishing with wings and
3) QB wings with HW extended tanks.
4) Finish kit and fwf.

Another RV-9 Takes Flight ...agirard7a
It’s been a six year project. It’s finally
finished and flies well. Weighed in at 1025. 160 hp.
Will contact with automatic transmission fluid harm aircraft tires?
Could not move my build project into my
hangar because of ATF residue on the hangar floor.
The previous occupant had a container of ATF that leaked from a
stored container onto the concrete floor when he was vacating the
hangar. The airport crew cleaned it up, but a substantial residue
covers about 400 sf in the middle of the hangar. I put some green
absorbent stuff down, but it didn’t help.
Next step is to power wash. I'm not on wheels yet, but won't move if
there is a chance the ATF might harm the tires.
Thanks in advance,

I was at the airport fiddling with some data

getting low in the sky, only myself to worry about for dinner, so I
decided with the impending "fall back" I would hang out and get

else in the plane.

Day 31 ...Scott Chastain RV-8
I packed up the air mattress and sleeping
bag and went downstairs at about 6:40 that morning. It was Sunday.
The TV was on with the volume up loud but nobody was in the FBO. I
put my camping gear and other bags in the Dove, then went back
inside and put the keys to the Ford Five Hundred on the counter. I
turned off the TV and took the coffee pot into the bathroom to fill
it up with water.
Just as I finished getting the coffee going, Steve showed up from
the maintenance hangar and asked me how Detroit went. I told him
that I had a great time in Detroit and that Michigan was a great
state to visit. I told Steve about the Tigers game and the arts
festival and the friendly spirit that filled the streets that night.
When the coffee was ready, I took a cup and sat down under the
staircase with Steve and started talking with him about airplanes.

have originated at Grosse Ile because of a forced landing made by a
TBM Avenger nearby. There was a framed accident report below the

Two weeks ago I got a flat on the nose wheel

However, when I removed the front tire from the rim, I noticed the

the walls of the interior of the tire. Typically, I keep the front
tire @ 40lbs but it's possible that during the slow leak period it

RV14 Exhaust hanger ...Tom M
I am noticing a bit of vibration in the
tunnel and side skins of the RV14. The aircraft is also a bit louder
in the cockpit then I am used to.
When I installed the aft exhaust pipe hanger I wondered why such a
solid metal arrangement had been used.
In the following picture you can see the stock hanger on the right
side and the "rubber" isolator that I fabricated on the left. I made
the hanger from automotive exhaust pipe hanger material. Both sides
now have the modified hangars and I will test fly it tomorrow. I
have never seen, on any equipment, such a rigid exhaust pipe hanger
as was supplied by Vans' for the RV14. The new set up securely holds
the pipe and I can not help but think it will help with both
vibration and sound. I will report back

Awesome! Visit to ITEC at PTZ, Shell, Ecuador ...punkin
On a whim and a nudge from above, I shot

see the ITEC shop and hangar. I'm so glad we did! Galo was

Q: This is the result I get when i give my
Avery speed deburring tool a 360 around a drilled hole. This
is a #40 drilled hole deburred and then dimpled on DRDT-2. Dimple
was done to improve visibility of the jagged edge of the deburred
I have tried using light pressure and heavy pressure fast and slow
with similar chatter. Do I just need to buy a new 3-flute cutter?
This tool was purchased new (in 2007) and has only been used on
about 100 or so holes. If this is normal and I am just looking too
close, I will be thrilled with that answer.
I am seeking your collective advice as I am now frustrated before I
have even started (this is a piece of scrap from a 2007 Oshkosh
sportair workshop that I was using to experiment on this afternoon).
I have also been having some issues with my drilled holes not being
round, but hopefully I solved that with a new set of drill bits.
A: 1/4" shank 3/8 diameter 100 degree
countersink, six flutes. MSC supply or industrial hardware store. If
you can't find a handle for it make one. I can't find a source for
the handle I have had for years. I used to be a fan of single flute
countersinks for deburring but got over that a long time ago.
A: Chatter results from a cutter that
repeatedly digs in, breaks loose, digs in, breaks loose. etc.. It is
a harmonic with the machine (you) spinning the tool or work piece.
There are lots of ways to address this, but often the easiest is to
change the cutter speed. Try spinning the tool faster or slower
while adjusting pressure.
The tool can also have the tip of the blade ground to an angle that
adds to chatter. In that case I have sometimes had success 'breaking
in' the tool by deburring a few holes in steel. Tools will change
over their life, depending on the wear, chattering only when fresh
or more typically when forcing a dull tool.
Otherwise replace with a different brand/batch tool to find one that
works for you.

Construction Video Update ...kiljoy RV-14
I've finally finished off both of the ailerons. Once I redid the
top skin for the right aileron everything fell into place nicely.
I've now just started in on the flaps. There aren't many pieces
thankfully so it'll probably just be one full day of deburring.
It's sad that I think about it like that. It's not, 'oh wooo the
flaps' its, 'oh woo more deburring'.
Anyways in my side job as maintenance officer I've got some
interesting real world stuff coming up. Going to assist in a field

that and most of the right aileron riveting. Enjoy.

Here is a picture of the brand new aircraft in my friend Ed Perl's

favour my runway.
A total of three flights today with a total of 3 hours. The aircraft
is in good flight trim with no serious squawks. The 390 engine is
quite powerful and the shortened RV10 wing is an excellent match for
the aircraft. Roll rates are a little firmer then for the RV7, an
improvement in my opinion. Cabin space is very good with excellent
This is my 12th aircraft completion and my 14th first flight. First

First engine start ...rvdave RV-10
Been waiting for this day for eight years, first engine start
went pretty well but a few items to address. Engine had been pickled
so a lot of smoking, left a wet trail on the ground and some on the
belly but quit smoking after a while. Rpm pulses needed to be
adjusted was showing double rpm. Thing I'm concerned about is I have
dual lightspeed ignition and when trying a "mag" check backfired and
so didn't try it again. Prop cycled ok after letting oil get to hub.
Brakes wouldn't hold during high rpm, need to check that maybe break
in brakes better. Need to look into lightspeed wiring before another
start. Happy though that this new engine is working, engine
parameters look good.

October Calendar Wallpaper
Officially Joined the VAF! ...Even Levesque chimes in
Finally joined the club! I just flew my new Vans RV-8 from Paine
Field, Washington to Hanford, California.
In 2010, when I was a midshipman at the Naval Academy, I went out
and got a tailwheel endorsement, in a Bellanca Super Decathlon,
because of an awesome little airplane I saw at the local airport
called an RV-8. It looked like a little P-51, and the owner said it
flew better than any other airplane he’d ever flown. It became a
dream of mine to someday own one of these beautiful airplanes.
Going online, I researched the airplane, and looked a numerous build
sites, to include Randy Lervold’s which had link to Michael Robbins
build site for his RV-8, N88MJ. The instrument panel and striking
Red and Grey paint job immediately captured my fancy, and those
pictures were my desktop background for a long time in college.
Anyway, I graduated (barely), and got busy with work and eventually
got to fly some pretty cool airplanes for the Navy, but I still had
the desire for an airplane of my own. I bought a share of a friend’s
Lancair 320 for a year to get a taste of airplane ownership, and
discovered that the weekend traveling lifestyle that a light
airplane brought was like catnip to me. Not to mention the awesome
airport community that begins to emerge once you are a fellow
As time went on, I’d continued saving pennies and the dreams and
tire-kicking looking for an airplane became more serious. Except now
that I had the ability, the number of RV-8’s on the market that met
my criteria (IFR, IO-360, Constant Speed Prop) that were within my
price range were slim.
I looked and looked until despair set in. Maybe I had waited too
long and all the good airplanes had already swapped owners. I didn’t
think my dream plane was going to be out there.

I have a few more updates of the build. Finished the step install

they were in the wrong location. Didn't get too anal about the plug

When I woke up, I went over to the FBO to wait for Heather. It
was kind of cloudy and overcast and I hoped the weather would
cooperate enough to let me depart Towanda that day. I thought I
would go into town to do some laundry. I had a lot of dirty clothes
to get washed, and I saw a good laundromat the night before when I
was exploring Main Street.
When Heather showed up, she brought me fresh coffee and I thanked
her. She asked how I slept and I told her that I slept great. I
asked her if I could use the vehicle again to go into town to do
laundry, and she said certainly.
Then a guy named Neil came in and Heather introduced us. Neil was a

Status Update in Videos (RV-14) ...kiljoy
Aileron work continues. I've gotten the left one completed and
I've just got a box from vans containing the replacement aileron top
skin for the right aileron. Why do I need a replacement aileron
skin? I MAY have scuffed, primed and dimpled the top right aileron
skin on the wrong side... which is ironic because I'd written all
over the skins with 'inboard', 'outboard', 'fore', 'aft', 'top',
'bottom', etc with arrows just to avoid this very thing from
happening. A ounce of prevention is worth $13 in shipping costs
Thankfully unlike a rudder skin, the aileron skins can be rolled and
shipped in a much smaller box!!
Anyways we'll get to that **** up and fix in the next set of feeds.
For now here are the next videos of the aileron construction from
earlier. It goes through deburring, dimpling, riveting etc. Enjoy.
Day 27 Part II ...Scott Chastain RV-8
I hit a lot of bugs going over the lake. My windscreen was
splattered with them. It was bumpy climbing up through the cumulus,
but pretty soon I was in smooth air again and topping out at 12,500.
I went through Vermont and over the Mt. Washington airport and
proceeded to the southwest into Pennsylvania. In about two hours,
the Lord sent me into a descent for the Bradford County Airport
(N27). There was a pilot in a twin with a foreign accent landing
ahead of me. He asked where the fuel was after he landed, and a
woman came on the radio and told him to go where the Phillips 66
sign was posted. After I touched down, I did the same.
Status Update ...David Paule RV-3B
Finally got the aft-most belly skin glued on. This is the one
right in front of the rudder. On the RV-3B it's .040 thick and in
previous posts you've seen it in progress at various stages.
I used West System's G/flex epoxy, the pre-thickened variant. This
is just thick enough that it doesn't run. It's too thick to laminate
with, being intended strictly as an adhesive. It's a relatively
tough, flexible epoxy but that's relative to stiffer varieties. I
chose this on the basis of good results reported by two very
experienced and knowledgeable friends. 3M's 2216 adhesive is another
that would work well, and perhaps better.
This particular skin was small enough that I could manage it all
myself, within the 45 minute pot life. I think that for anything
larger than this I'd need assistance.
In the photo, I've got the longer tailcone belly skin clecoed on
just ahead of it, to its left.
This aft-most belly skin still needs rivets. More than that, it
needs countersinking too. I decided to wait on that until after
gluing because even for .040, there's not much cylindrical bore
remaining after countersinking, and I wanted the clecos that were in
place while the glue set up to give good alignment.

High River AB Direct To Fairmont BC ...Troy Branch
On Sunday I took a friend up for a first flight in a small plane.
The day was one of those perfect go any direction days. We say that
living next to the rocks as there is many days you cannot go west.
We climb out west bound for 10,500 on a perfectly smooth flight over

perfect weather. He liked the 30min flight much better than the 4
hour drive. To say the least, he was impressed with what our small
aircraft can do. Every flight makes me smile and this flight might
have made me smile a bit more.
"Interesting" wake encounter ...Steve Smith RV-8
I was cruising north along the Sierra foothills, close to Auburn,
when ATC alerted me to a DC-10 Heavy descending across my path 15
miles ahead of me.
The controller initially recommended a heading change 15 degrees
right, which would mean that I would have crossed the flight path of
the DC-10 farther behind it, and at a point where it had been
I replied that I had the heavy in sight, and the controller said,
"resume own navigation, caution wake turbulence."
It looked to me like I would cross the jet's flight path at a point
where it was still a few thousand feet above my alt, and about 25
miles in trail. I know that the wake does descend a lot (wake
modeling was a big part of my Thesis research), but I just continued
Sure enough, right when I was directly in trail of the DC-10, now
about 25 miles away, BOOM! I hit his wake. It was a very sharp
up-down-up jolt, of which I predominantly felt the 'down'. As I was
getting my eyeballs tucked back in where they belong, I noticed that
I had a low fuel pressure alarm. About as quickly as I noticed it,
the fuel pressure returned to normal. The engine never hiccuped.
I find this interesting. The tank was within 5 gallons of full. So
it is not like a big slosh would have left the fuel pickup dry. Or
would it? The heave was so fast, and over with so quickly, it is
hard to imagine a large air bubble at the outboard top area of the
tank could quickly travel to the bottom inboard area of the tank. In
order for that air bubble to move, fuel would have to move to
I wonder if the fuel pressure loss could be due to something other
than the fuel pickup momentarily being in a big air bubble. Could
the rapid acceleration interfere with the mechanical pump function?
I don't know.
My G-meter showed +4 and -2 g's. Thats a +/- 3 g excursion from
Day Twenty-Seven- Part I...Scott Chastain RV-8
I've gotten some local attention on my 48 state trip in the form
of a newspaper article from the Grass Valley Union:
0.0 Fuel pressure while on cross country
I think I need a new fuel pressure sensor. Shortly after a
refueling stop with 100LL, the fuel pressure started to swing
rapidly from 1.1 to 5.0 psi at 5400 RPM and suddenly stopped at 0.0
psi. Engine was running fine. I made a precautionary landing to
check out the problem.
On the ground I determined that I had fuel pressure that wasn't
registering on the G3X. I could hear the electric pump running and
tested the flow from the gasolator to confirm the pump was indeed
It was very hot out and I decided to let the engine cool for a
couple of hours. When I powered up the G3X the fuel pressure showed
max fuel pressure 14+ psi. As soon as I started the Rotax, the fuel
pressure started to swing up and down and stoped at 0.0 psi.
I unplugged the sensor, removed the rubber seal and reattached the
plug with no change in the reading.
After extensive taxi testing and run-ups I finished the flight.
I will order a new sensor unless some one has had the same symptoms
and resolved it using a different method.

I would like to send out a huge thank you to 52F property owner Sam
Daniels for quickly troubleshooting the a/c problem on our '07 Honda

Sam strolled in today and found it in three minutes.
Compressor still didn't work. "Which relay is the

drone. A business expense for more creative RV photography - 12
megapixel stills and 4K/30fps video. I've been looking at
these for awhile, but couldn't justify the expense. The
technology is mature, and the feature set now is insanely
robust....it was time.
I'm still getting acquainted with it,
but it's getting easier. It is a DJI 'Mavic
Pro', and the
test footage above is using the 'Point
of Interest' intelligent flight mode. Basically, you mark
a spot and it will orbit it until you tell it to stop.
1989 I flew an
X-cell 60 r/c helicopter. No gyro stabilization - Mark 1
eyeball only. Stress. This drone thing isn't even in the
same solar system. It's crazy simple. Crazy.

How to minimize ground loops
I had a quick question about ground loops. I am going to be
wiring a PMA 8000 series audio panel to an old KX-170B Nav/Com. The
KX-170 used unshielded wiring and lacks pinouts for "audio low". I
wanted to know which would be the proper method to wire the com
output to a modern audio panel.
The first option would have the audio low outputs for nav and com
brought together to the current airframe ground at back of the
KX-170B. The shield terminations would be grounded at the audio
panel back shell with everything else.
The second option would have the low audio outputs for nav and com
brought back to ground with the shield terminations at the back of
the audio panel (all grounds shared at the back of the audio panel).
Seems like the second option would be the preferred method for
minimizing ground loops, but I wanted to check with the group. I
can't seem to find much in the way of printed guidance on these old
- new interconnects.
Day Twenty-Six ...Scott Chastain RV-8
When I woke up, it was plenty light outside, but there was a low,
thick overcast and it did not look like good flying weather.
24 years ...Tom Martin
The month marks a milestone for me. I was 24 years ago, this
month, that I purchased a RV4 kit, sept 1993. There was no VAF, very
little internet action; I was not even aware of the EAA. I had a
citabria at the time and wanted something faster. A friend suggested
a RV4 and I had the very good fortune of going for a ride in Rick
West's award winning 4. He and Gord Baxter, RV6, another excellent
RV builder provided my support network. I knew nothing, but I had
built many projects on the farm and was well equipped with a shop
and misc tools.
I stared at the project for two months and then got to work.
Seventeen months later it first flew. I thought that I would own
that plane forever but I was now addicted to speed and had heard
about the Harmon Rocket. I built two of those and then along came
the F1 Rocket. I completed 4 of the standard wing F1s and then built
a F1 with the EVO wing for myself. I love that plane and still fly
it. For five or six years I was quite active in the Sport Aircraft
Racing league and the plane did really well. Constant changes to the
cooling system, airframe cleanup and prop changes added over 30
knots to my top speed. The aircraft is remarkably efficient and my
wife and I typically do a few cross country flights. We have been to
the east and west coast, and most of the midwestern and eastern USA.
Along the way a RV7 and a RV10 were also completed in my shop.
I took a couple of years off and have just finished a RV14. The
final inspection was last week and I am waiting for the flight
permit. The "kits" have improved remarkably over the years but it
does not seem to have shortened the built time. When I started there
were no autopilots, basic simple panels and gps was just being
thought of. Every year the aircraft get more complex with more and
more systems. These systems add time and weight to the aircraft.
Although the equipment is truly amazing it does add to built time. I
am looking forward to flying the RV14, I have about 30 hours in the
10 and I loved the lift and I expect this plane to climb similar to
the 10. It should be a lot of fun solo with half fuel.
It is hard to believe that 24 years and 12 aircraft have passed and
I have met the most wonderful people in the aviation world. People
ask me if I am going to build another one and I just purchased a
high end cabinet saw as I would like to get back to my first love,
woodworking. I have this big pile of Ash in the barn and I am
thinking an all wood motorcycle or car would be a neat project. I
might even throw in some aluminum bits here and there!

Continuing a family tradition, Ryan is the 4th member to complete a

Pictured below is Ryan on the ramp at Sanford Intl (KSFB) after his

and lows filled with fear of what might no go as planned. In typical
Ryan style, he made us all proud and left everyone at the top of the

In the interest of safety I want to let you know I had a carburetor
failure on my Warrior the other day. It is a Marvel Schebler
MA-4SPA. Not sure, but this might be a standard model on RVs as
In this carb, the fuel bowl assembly is bolted to the venturi/throttle
assembly via four body-bound bolts that mount through holes in the
throttle assembly to sockets in the bowl assembly. The bolts are
secured with locking tabs and not safety wire.
Due probably to vibration
and in spite of the locking tabs,
the bolts had loosened and then damaged the threads in the bowl
assembly. The carb bowl was separated from the throttle assembly by
about 1/32 to 1/16 inch and very wobbly. One bolt was almost

The Dimple Fairy?
R-903. The last four holes have been dimpled, but not by me. Any
suggestions.....? Brand new kit I picked up from Vans myself.
Don't get me wrong, I know these are difficult to do. But, I did not
think Vans was in the business of helping builders with dimpling.
A: Van's does some dimpling for us on occasion. I for one welcome
our new preemptively dimpling overlords.
A: I've noticed that
dimpling has been done when it's an odd sized dimple die that the
majority of builders won't have in their tool kits. In the end
I see this as a way of increasing the quality of the end product.
A: RV12's have quite a few pre dimpled bits and
pieces - like you say, difficult places or strange material like
A: Not a -14, but I was thinking the same thing looking
at a rudder piece. I was wracking my brain trying to remember if I
dimpled it or not, but realized that yeah, it was pre-dimpled. It
would have been a pain to dimple (trailing edge rudder rib), so I
welcomed it. Now if we could convince Van's to do more...

Nose Gear Lessons Learned ...BMW_X6M
Oversize AN175-20A bolt solution worked for me. My RV-9A
has 800 hours now, and made some noise from the front gear when
using the toe bar. I found I could rock it back and forth very
slightly with the weight off of it. I purchased the oversize bolt
and metal lock nut, and it went back in snugly, having to turn an
old nut on the bolt to seat it. After final torque with the new nut,
I have no more play in the gear. This is obviously a huge
relief and thank you for the creator of this thread. It proved to be
valuable information for this non builder.
Eagle's Nest Projects - Two 1st Solos / 1 day and 1000 miles apart
Day Twenty-Four ...Scott Chastain RV-8
Lycoming Carbureted O-290-D2 EGT out of Family
Something went amiss two days go on a 1 hr. cross country flight
at 7,500' and I'm searching for ideas. Perhaps someone here can
point me in the right direction. My normal routine when reaching
cruise is to pull out the mixture control maybe 1", let things
stabilize for a couple minutes as the speed builds up, then start
the leaning process with my JPI EDM-700. I usually lean to peak and
leave it there unless the engine is running rough. In that case, I
enrichen 50 degrees. My four bar EGT display usually isn't quite
level, so I adjust the throttle a tiny bit until all four EGTs are a
straight line on display. The throttle butterfly works magic to even
up my fuel distribution.
So on this flight, EGT 1 (red line) was way low (230F), and EGT 2
(green line) was also low (150F). No matter how I fiddled with the
mixture and the throttle, I couldn't get that nice straight line.
The engine wasn't running rough, but I could feel an unusual
vibration. My airspeed was normal, so I kept on to my destination.
(My runup had been completely normal with equal mag drop on both

Reminder from Cynthia at the Mothership
Dear Builders and RV Owners,
This is a gentle reminder for those of you who are
about ready to
register projects with the FAA, and others who have purchased
projects from other builders.
For FAA paperwork, you need to have the License Agreement and Waiver
on file with Van’s. ( And, yes, the License Agreement needs to be
notarized). Also, you will need to fill out the questionnaire aka
Document Request Form, so I have the correct information for the
8050-2 Aircraft Bill of Sale. Please note that the
account/builder/serial number assigned by Van’s will be the only
number used to identify your project on the 8050-2.
For ownership transfers, I need a copy of the bill of sale as well
as the License Agreement and the Waiver signed and on file. This is
inclusive for projects and flying planes. For “orphan” kits, an
affidavit detailing the history of the kit to the best of your
knowledge with as many possible names and addresses relative to the
kits’ history will need to be written up and signed before a notary
public to create the best paper trail possible for the FAA. I will
need a copy of the affidavit for the file.
Without exception, all documents can be scanned and emailed, faxed,
or posted in the mail.
If you have any questions, please contact me Monday-Thursday from
8am-4pm PST at 503-678-6545x322 or cynthia "at" vansaircraft "dot"

The W&B thing(part 2)- IS RV-Fun inversely proportional to
A recent thread I posted on the importance of accurate W&B docs
generated a lively discussion and lots of valuable shared experience
from veteran RV builders and pilots, so I thought it might be
worthwhile to expand the discussion in a few other directions. If
this one gets a similar response, the next will be about the
temptation to nudge the GW limit upward a bit during the
registration process. Stay tuned.
This thread makes reference to the "selfie-quote" In my VAF
signature, which seems to have ruffled a few feathers already. Is
"RV-Fun is inversely proportional to RV-Weight" a valid statement?
Should it be of concern to all RV builders? It may be a bit cryptic,
but I think it IS valid for any given RV configuration of engine,
prop, and instrumentation.
I'm not an aerodynamicist, and my hard knowledge here is dwarfed by
my ignorance, but I do have a limited qualification to bring up the
subject based on my experiences as rookie CAFE Foundation
test-pilot/author or flight-engineer/volunteer for most of the CAFE
APR series published in Sport Aviation during the 1990's, which
included four RV models. During these APR's, we measured stick force
gradients, explored stall recovery behavior, and flew a structured
handling qualities protocol in multiple loading configurations for
each aircraft tested, and the overall experience was a real eye
Actually, I'm betting that you RV-vets will have more interesting
things to say than me here, so I'll make just TWO points and cut
1-Absolute Weight- The rewards for lower empty weight are improved
performance at any given load and a higher useful load, both more
fun in my book. Fortunately, one strength of all Van's aircraft is
that they are intrinsically light in weight if built according to
the plans, but the designs are also quite sensitive to excess weight
for reasons too complex(and too over my head)to fully address here.
Ending up with a finished aircraft that is within Van's guidelines
requires incredible discipline every step of the way. Weight goes on
a little at a time, and the temptation to add more features and
equipment because each will "only add a few ounces" is a slippery
slope. Those of you just starting to build are in a position to
adopt a very strict attitude about weight and maintain it through
the whole process. Is it really worthwhile to prime all those inner
surfaces on an airplane that will be babied in a hangar? The tired
old saw has some truth: "If you are thinking about adding something
to your airplane, toss it in the air. If it does NOT fall to the
ground, then it is OK to install it."
2- Polar Mass- Of course, everything you put on that airplane is
subject to gravity, but there can be very compelling reasons to do
so. Not everything has the same impact, though. Comfy seats are SO
nice to have, and actually not a bad place to splurge a little
because they are practically inside the CG range. A CS prop will be
a must-have item on the RV-7A I am looking to buy, and the
impressive speed range of most RV's simply cries out for CS, but
there is a real price beyond dollars to be paid. Unfortunately, the
gold-standard Hartzell is heavy and as far forward of CG as you can
get. Flying with a forward CG requires extra down-force from the
tail, which requires additional up force from the wing, etc.,etc., a
drag-inducing positive feedback loop that, carried to the extreme,
can compromise control authority in flair, reduce cruise performance
efficiency, and make the aircraft sluggish and unpleasant to fly.
The lightest weight solution to these problems is a bit of lead as
far back in the tail as you can get. Now you have a better balanced
airplane for control authority and efficiency, but one that handles
a little bit less like a mid-engine sports car and a little bit more
like a dumbbell. The prop and ballast have slightly increased
resistance to control in the pitch and yaw axis. A heavy paint job
would do the same, but with a price in category one too. A very
strong argument can be made for saving even 8-10 pounds at the nose
with a composite prop if, like me, you must have CS.
Or maybe you are ready to give up the CS advantages for a nice,
light FP prop and maybe even a lighter engine. Great, you have just
solved the polar mass problem and will have an incredibly nimble
airplane that is a delight to fly. Now you must REALLY pay attention
to the CG, limit luggage, hang everything you can toward the front,
and really fuss over making the paint job light, or even go without,
or you may find yourself needing to add one of those 20 pound crush
plates behind that lightweight prop. (Or hey- maybe I SHOULD
consider a whirlwind? Sheesh!) Every choice has a consequence.
Full Castoring Tail Wheel-All The Time

Longest flight legs?
I originally built my RV9A with the intention of taking that
"some-day" trip around the world with it, which means some rather
long flight legs over water. With that in mind I installed outboard
wing tanks that give me 67 total gallons, and with a 66 gallon
Turtle Pac in the right seat that puts every reasonable oceanic
route within reach. As I've been building time on the airplane I
like to take longer and longer legs to learn what is needed to keep
the airplane happy for those long flights as well as keeping the
pilot happy. Yesterday was my longest flight leg to date, coming
back home to west Texas from Carson City NV after the Reno Air
Races. I logged 1005 nautical miles in 6.5 hours (engine start to
engine stop) at 17,500' all the way, burning just 40.3 gallons total
with a bit of a tail wind. I'm finding that I'm perfectly
comfortable sitting in the cockpit that long and could easily do
more, and I'll continue working my way up to the 14 hours that would
be needed for California to Hawaii. I'm flying the Classic Aero
Sportsman seats and love them.

An RV-10 Milestone! ...Ivan Kristensen
Yesterday during an IPC (Instrument proficiency check) I topped the
1000hr. total flight time in my RV-10. This airplane has proven to
be a great traveling machine with trips from coast to coast. From
Moosonee in northern Ontario to Grenada in the Caribbean and many
many places in between.
I began building this airplane in April of 2008 with the first
flight on June 28th. 2010. The picture was taken at the
Marathon airport in the Florida Keys about a year ago. Oh yes,
did I mention that I passed my IFR flight test...
Three in-flight failures
1. An alternator failure at 10,000ft. over lake Erie, returning from
Florida, in semi IMC was a significant event in that is caused a
spike in voltage causing the VP-200 to shut everything down. In
other words ALL instruments and both EFIS screens went dark, a
pilots worst nightmare. With some difficulties hand flying using the
standby and internally battery powered Dynon D-100 on the far right
of the panel the problem was resolved by re-booting the VP-200, no
instruments were damaged so the sec. alternator was brought on line
and landed 1/2 hr later at our home base.
2. Again, returning home from the US we were at 14000Ft to top some
cloud and icing in very cold temperatures. a further climb was
needed to stay out of icing. The A/P was set to command a climb but
instead of the airspeed going to 120kts it started to climb. This
situation was soon recognized as a blocked/frozen Pitot even though
the Pitot heat had be an all the time. Some of you will remember
that the Dynon Pitot head had an issue with passing water past the
mast into the line allowing it to freeze. Dynon has since replaced
all affected units free of charge
3. A complete Magneto failure was experienced returning from Oshkosh
in 2014. This was a total non event in that I didn't even know it
until a couple of days later when I went to do the pre-takeoff
run-up. During the Mag check when I switched off the EI the engine
almost quit. Oil had gotten past the seal and saturated the Mag.
(One magneto and one Lightspeed EI)
Some notable upgrades along the way
1. With my alternator failure it was obvious that my electrical
system was inadequate. An 6amp IBBS system from TCW for backup pwr.
to both EFIS' and AHRS' was obtained and installed. Bob Neuman from
TCW was a great resource with answers to design and installation
2. A Garmin G-5 EFIS with GPS and internal backup battery was
installed on the left side on the instrument panel where it can
easily be seen.
3. The Garmin GNS430W was replaced with an Avidyne IFD440 which is a
"plug and play" upgrade. This was a significant change and
definitely one for the better. The IFD440 is a modern, easy to use
large bright touch screen interface with many new features incl
4. Recently I also upgraded one of my Grand Rapids Technologies (GRT)
EFIS screens from the 8.4" HX to the 8'4" HXr touch. GRT are doing a
great job in bringing the latest technology to market and the HXr
touch is no exception. This unit brings with it many new features, a

The sleeper awakens! (My engine, that is) ...Scott Balmos
This past Saturday afternoon, after 5 years and 9 months of
building, I successfully managed to awaken my plane's engine from
its 13-year slumber. She kicked and protested, wanting to go back to
sleep twice. But the third time around, I got the gas-to-noise
generator to stay up and going.
FIRST ENGINE START WAS A SUCCESS!!!!
For reference, it is a Lycoming IO-320-E2A, running the full EFII
injection/ignition system, spinning a Catto 3-blade wind generator.
The engine was overhauled by its previous owner between 2004 and
2006, and then put into storage. Needless to say, I was
subconsciously a nervous wreck, deep down not knowing what to
expect. I readily admit that once I had run up to 1800 RPM, saw the
temps and oil readings were fine, I took a few seconds to just sit
back and enjoy the wind and noise.
A thank you to my Dad for the videography, RV-14 builder Bill
Schweinberg for a few checks on attempts 1 & 2, and then a major
major thank you to RV builder extraordinaire Jon Thocker of Redline
for doing the run-up walk-arounds once the engine cooperated on
attempt 3. Jon just happened to be doing his usual biking around the
airport Saturday afternoon when he stopped by while I was prepping
for attempt 3.
Afterwards, more than anything, there was a huge sense of relief.
Here on out, it's bug-fixing and finishing work. But now I know I
have, in the most important mechanical sense, a working plane.

Well one year later on my 61st birthday the stars aligned. After a
frustrating delay of two weeks due work , weather and a bad head
cold my RV7 took to the air. The first takeoff was so quick
"Kamina" flew dead straight , everything worked and an hour of
circles over the field flashed by, with a small skip on landing. Had
a good look around and Took her up for another 20 mins. More today.
Thanks to Doug and all on VAF for the incredible resources.

Final Report Issued ...RV-6A tip up Australia
In October 2014 an Australian registered RV6A crashed
catastrophically into a laneway in a densely populated suburb of a
major city. The aircraft hit two houses and several cars and the
pilot died on impact.
The Australian Transport Safety Bureau investigated the accident
comprehensively and subsequently issued a final report. It suggested
that the most likely cause of the crash was the tip-up canopy coming
open during flight. For those with a tip-up canopy RV this report
will be compelling reading.
Plagued by Engine Stumbling ...Azjulian
I have posted about this before and I thought that I was past the
issues, but they seem to have started again. At full throttle I
occasionally get an engine stumble, this happened again today twice
just after take off and led me to abort the flight.
I have done the following
- taken both carbs completely apart, cleaned with air and carb
- checked all my fuel lines, at each connection I have run a volume
of fuel over time test and I have run several gallons through the
- checked my fuel bowls for any contamination several times
- re-synchronized my carbs both mechanically and pneumatically.
The problem had all but disappeared until I experienced it at
alititude (9500') on a trip to Payson recently. I confirmed my
engine was on the float exchange service bulletin and I swapped all
my floats out (one side was 7.7g). But after the float exchange
problem seemed to get worse...
As you can see in the image below, when the issue happens its
preceeded by the left EGT going 100F hotter than the right (this
always happens when you look at the logs).
I also should point out that my static WOT RPM and my climb RPM are
pretty much the same, and in climb I seem to lose 50 or so RPM as I
climb out, that to me is wrong, but I cant seem to trace any cause
and my CHTs and EGTs are cool...
At this stage the only thing I can think of doing is trying to swap
out carbs, that it is some strange carb related issue... Can anyone
help ? Please
I have to say this has totally sapped my enjoyment of an otherwise

On Sept 7 I was at 4,00ft IFR talking to Eglin approach on my way
to Milton, FL (2R4) when my SkyView display started giving me a
"Traffic Warning". The ADS-B indicated I had traffic 3 miles out,
approaching me, head on at my same altitude. When the alert showed
the traffic at 1 mile, still approaching me head on and still at my
altitude I firmly pulled the nose up and turned to the right. A few
seconds later I saw a twin engine airplane, about 100ft below me,
right where the ADS-B was showing pass by.
When I got over the "scare" I told the controller what had just
happened. The controller sheepishly told me it was a Seneca
maneuvering in that area. Needless to say I let the controller know
I was a little upset about what happened. When I got on the ground I
filled out a NASA form just so my little grain of salt is entered
into the system.
I don't know if I would I have seen the traffic without the ADS-B
"point out" but being able to know where to look for traffic is a
significant safety enhancement. In this case I didn't actually see
it until it was extremely close. I am so glad I have this in my

From The Mother Ship: The first RV-14A to fly in Europe
Plane is based near Stuttgart, Germany. Builder is Stefan
"The story started at the AERO exhibition in 2016... where I sold my
the real story started at Vans in Oregon in 2005 when I visited Vans
Aircraft. The adventure began when I met DARYL (Mr. VERY EASY
and Mr. NO PROBLEM).
I bought a RV7A because Daryl was so enthused and spoke so much
about this model that I didn’t dare not to sign the order. Please
don’t ask me how many problems I had to face, or the mental battle I
had with myself after signing the order.
As a result of this signature, I spent more than 3 hard years of my
life building an aircraft. Thankfully Daryl was always at my side
from across the water with plenty of support and advice. (Sometimes
he solved the problem).
the AERO 2016 exhibition last year, a genuine earl came to the stand
and asked Daryl if he could buy my aircraft.
Daryl simply suggested, “ask Stefan NO PROBLEM”... and this in fact
was the trigger to the second story. Again I went to Oregon,
visited Vans or better still visited a very enthused Daryl and again
he spoke a lot how great a RV14A would be especially for me... same
story. And we all know how the first one ended. This time
after only 12 months of building I could put the painted parts
together (prop., engine and all other pieces mounted à la Daryl) and
I had my first flight on 29th of August in EDTY.

Q: Avionics Cooling Fan
What have you guys done about that? I am at that point so trying
to get ideas. I love to use the cyclone 21-3 but the price is pretty
steep for a fan!
Got ideas and pics to share?
A: (Stein from SteinAir) Many of the modern avionics and EFISes
have their own cooling fans in or on them, and in addition to that
perhaps the most important thing is to have some sort of vent holes
in the glareshield (or even a couple muffin fans). That should allow
that dead space between the main panel and sub panel to be
ventilated and kept at a good temperature, so everything should be
good (as Bob noted, those glareshield fans also work as defrosters
Just my 2 cents as usual!

Time for Some Overdue Refurbishment ...Bill Boyd RV-6A
I'm looking at a disgusting mess, here. Almost sorry I didn't
snap pictures last evening to illustrate. None of this is new, but
it's in my face now, having reached a point where I can't keep
ignoring it simply because flying is more fun than fiberglass work
(who knew, right?
I pulled the cowl to begin replacement of my alternator and DC power
distribution wiring. It was ugly. The glass is wearing badly where
the nose gear strut meets the lower cowl. The lower cowl is
heat-discolored from gradual loss of the aluminum foil I glued
inside (not well-enough) 20 years ago. The engine seeps some oil,
now, which finds its way to the bottom and has saturated the
composite where I failed to seal it well enough, or at all, with
resin during construction (I could fill a book with things I know
now that I didn't know then. This is such an educational activity
) The gel coat, and with it, the paint has spider-webbed in a
thousand different stress concentrations all over the outer surface.
The shoulders of countersunk screw holes are wearing oversize and
The DuPont polyurethane paint formula I'll need when I'm finally
ready for basecoat/clearcoat repair was lost in a house fire, so
we'll have to color match by other, imperfect means.
I am confident after all my recent RV-10 canopy top experience that
I can fix these issues with epoxy, cloth and micro. But I'm not
confident I can get epoxy to adhere properly to oil-soaked
fiberglass. It's literally oozing through exterior pinholes that
have opened up in the toasted areas near the exhaust pipes.
What's the best way to try to clean this mess up for repair? I'm
sure it's going to involve elbow grease and a hazmat suit

Relocation from Hurricane Ins. Info ...Gallagher Aviation
With the payout usually only being $500 to $1,000, most insurance
companies will not take the relocation reimbursement into
consideration when writing the policy. The insurance companies would
still need to know about the event, but it would be more of an
activity rather than a claim.
The point of offering the relocation reimbursement is so the
insurance company does not have to pay for the full hull value of
the aircraft. You are taking care of your aircraft in a time of need
which helps both you and them so the insurance companies will not
punish you for that.

I have Vans repair kit and now have 5 large holes in the rear
baffle. I have started scraping away the somewhat marginal proseal
fillet along the rear baffle, fiddly work but quite doable.
My real question is "what tool do I use to add a new fillet?" Since
it's essentially in a blind location and mirrors are needed my usual
popsicle tool or SEM air powered dispenser won't work.
How have others got their goop into place?
I intend to remove as much of the existing skin/baffle proseal and
hen use adhesion promoter under the new proseal. Since it will be 85
F plus in the afternoon in the hangar the proseal should flow fairly
Some things I found out already that might help others -
1. 5 inch holes are easily cut with a m Milwaukee hole saw from the
local Ace store. The manager said it's probably the only one he's
sold of that size.
2. The part of my Pepto-Bismol cowling that was cut away for the oil
door makes a great proseal scraper.

These wheel/skis were designed as a safety solution in case I need

but it was kind of its limits, not designed for real deep or slushy

So I've polished off most of the elevators. The leading edges are
done. I learned from my rudder experience and these went down very
smoothly. I only accidentally put the lower skins on top of the
upper skins on only one section of one elevator. Thankfully that was
caught before riveting.
Anyways I've moved onto the wings. Inventory is done which is always
fun. I've started on the ailerons first. I'll be doing those and the
flaps first since they're small and I can hide them away. I'm
basically doing all of the smaller work first. I may even do the
tanks before the main wings? Not sure yet.
One thing I do know is that I bought crappy drill bits and trying to
drill holes through that stainless steel counterweight bar has
ruined about 3 drill bits so far.
On a side note my available building time I'm afraid is going to
possibly be going down. The maintenance officer on the board of my
flying club has retired. I was approached for the position and I've
been elected to do the job. Now on top of my plane I'm responsible
for maintaining a fleet of 4 aircraft and the 130 member's lives

Did you know that many aviation insurance policies will reimburse
you to move your aircraft out of the path of a named hurricane or
In light of Hurricane Harvey and the incoming Hurricane Irma, we
wanted to remind you to check with your insurance company about a
possible hurricane relocation reimbursement program. Each company is
different, but several offer a reimbursement program if you have
relocated your aircraft to be out of the way of an the oncoming
hurricane. These companies would rather pay the reimbursement
expenses (usually up to a set limit) rather than pay for a totaled
aircraft. If you’re wondering if your insurance company partakes in
a program like this, it will be listed in your policy. You can also
contact your insurance broker for more information.
If you were unable to move your aircraft and need to turn in a
claim, here are numbers for the companies we insure Vans Aircraft

Yesterday my plane took to the skys at Lebanon-Springfield

a fellow forum member as well as an RV-7A builder/pilot. Bobby flew
two 1/2 hour sessions feeling out the performance and

accepted that task for me. Feedback from Bobby is such that I have a

have someone more experienced take on that test pilot task.
A few more hours of dual and then I can do my first flight in my 9A.
Need to improve my crosswind skills seeing that's all we have here
Day Fifteen ...Scott Chastain RV-8
It was Friday, July 14, in St. John the Baptist Parish
when I got up that morning to make some coffee in the kitchenette.
As I was packing up, there came into the terminal building a man by
the name of Landry, the flightline employee and fueler for the
airport. He was wearing a white U.S. Air Force hat and he spoke in a
thick southern drawl when I introduced myself and told him that I
would be topping off shortly and taking off.
After I packed up and preflighted the Dove, I pushed her over to
the pumps. I was filling up when Landry and three other men in dark
blue uniforms came walking over. One of them said, “Good morning!”
and I did the same in reply. Landry introduced the men. They worked
for the Port of Louisiana Marine Division.
I thought I was in trouble for something. There were those grain
elevators loading up a ship on the Mississippi the night before, and
for a split second, I thought maybe the port authority was there to
investigate me. I thought maybe the guy on the golf cart reported
the New York license plates on the Sentra and maybe found my witness
of the levee operation suspicious.
Ritchie, the oldest in the group, introduced himself as a Commander
in the Marine Division, and he said that he had worked there for 17
years. Then Ritchie told me that he and his men had come out onto
the ramp to learn about the 40-day flying mission I was on, to learn
about the Dove, and to just walk around her for a few minutes to
admire the aircraft. Ritchie asked about where I came up with the
name, Descending Dove, and when I alluded to the anointing of
Jesus by the Holy Spirit following his baptism, everyone in the
group knew about that biblical scene and suddenly took a renewed
interest in the mission I was flying through America.

Completed first solo ...RV-7A builder Garet Hess
A bit of a pat on the back moment for me... Well happy to
report that I have completed Ground School and wrote my PPL written
exam, so I finally have time to get back on the build. But
more importantly August 28, 2017 marks my first solo!!! It's
strange how quickly things fall into place for a student pilot. I
was feeling so out of place on landings not long ago, then all of a
sudden things click. Next thing you know your all alone in the plane
with so much elbow room and your knocking out circuits all by
yourself!! Sad that the first solo is over so soon....Looking
forward to all the future solos.

Meeting VAF Friends in Northern Italy ...Lucaperazzolli
It's always a joy to receive a visit from a VAF friend.
It's the beautiful thing of RVs family. Here we are, in my
hangar with Ray and his loved Jenny (she's taking the picture).
We spent an afternoon together (RV talking) with pizza for dinner in
company with my wife Katia and my daughters. They are from
Australia and Ray is building an RV-7A, ready to install the engine.
Rest in Peace Logan Mason ...Bob Kelly post
Logan Mason passed away last evening. He was 19.
Most of you didn't know Logan, although some may have met him at
Oshkosh, 2014. Logan was an RV-12 builder, first with Eagle's Nest,
then with AviationNation. He had worked on three airplanes and was a
At Oshkosh, I was quite disappointed in Logan--he couldn't keep up
with the group. He was 14 and I was 70. Two weeks later he was
diagnosed with bone cancer. Logan laid out of school for one year
getting treatment. When we started AviationNation, he was back for
his senior year and back to building. He really wanted to build, and
to fly. He was a big plus to the build process. All the students
will miss him. So will I.
Day Fourteen ...Scott Chastain RV-8
I woke up earlier than usual in Adel, then went back to sleep.
Eventually, I got up and packed my things. I did not want to say
goodbye to Adel. It was such a friendly place to stay that leaving,
although it was something I had to accept, almost felt like a very
unfriendly thing to do given how well I was treated there.
A pilot came early that morning and took the C-150 up for a flight.
I saw the Dove sitting alone on the tarmac as the morning sun
reflected through the glass patterns of the terminal building onto

NE Acro Contest ...Oliver Spatscheck
Last weekend I finished my 3rd acro contest (2nd sportsman
contest) and I am still somewhat disappointed that there are no
other RVs around in the North/East. Only one I saw was Ron last year
at Mason Dixon which is really the southern part of the North/East.
Anybody out there?
Next contest I will go to is Keene Fall Classic
I haven't been there but that seems like the perfect contest for
somebody to get started. Only one day long, only primary and
So you don't have to worry about the 3 overnights. Taking vacation
on Friday etc... .
Anybody up for it? I am at N40 if you want to chat.
Reno '17 ...Ross Farnham
With Reno fast approaching, I'm looking forward to meeting many
VAF members and others there on Saturday and Sunday. I'll be hanging
around the Sport Class pits near Andy Findlay's orange Stihl Lancair
(Race 30) a lot. Look for the guy with the SDS T shirt and feel free
to tap me on the shoulder.
There will be some new entries in Sport Class which is good to see.
Should be a great time!

year the Gathering is on for Nov. 3, 4, & 5 and the Petit
Jean RV'ator group(s) are planning on making this years RV Gathering
one of the very best! Always big thanks to the Rockefeller
Conference Center and Arkansas State Parks & Tourism. Couldn't do it
without them. :--) Lots of news so don't expect short
Last years event started with 300 OVC and ended with maybe the most
successful and satisfying Gathering ever! When the OVC lifted on
Saturday, we had 71 airplanes arrive between 11:30 and 1:30. ATC
said we were the busiest airport in Arkansas .... for a day.

and file IFR into KCXO…the TFR should not be a problem. If you want
to enter VFR (via Flight following), you will need to call the FAA
and receive a squawk code (same code used for departure).
Call 512-782-5447 and tell them you will be delivering supplies
(baby formula, diapers, sleeping bags, toiletries) into KCXO and
need a squawk code to enter the TFR. They should provide the code.
Be sure and call before you depart. It is important to squawk the
code upon departing the TFR as well and then release your code once
clear of the TFR so others can get a code. ATC should accommodate
Thanks for caring...
Day Thirteen ...Scott Chastain RV-8
It was dark outside when I got up around 5:45 the next morning in
Immokalee. I stuffed the bag into its sack and brought my gear out
to the plane to pack up. I found a bright green tree frog enjoying
itself on the vertical stabilizer. Condensation covered the plane
and the air felt like something you could almost swim in. Before I
cranked over, I pushed the Dove over to the pumps to top off.

ADS-B Rebate Flight Success (I think) ...Ed Wischmeyer
When I bought my RV-9A, it had a primitive UAT out transmitter,
the kind that, if I recall correctly, had a non-approved GPS
position source, the aircraft N# code (in hexadecimal) and
transponder code had to be set before each flight with a cell phone
app, and no barometric altimetry. I flew with that a while, but it
got 86ed when I did the big panel rework.
So along comes the rebate program, and the first step of the web
application was rejected because my plane was previously ADS-B
equipped. I wrote to adsbrebatehelp.gov and explained the situation.
They saw no evidence of any earlier flights with ADS-B so we’re good
Then that evening, they wanted make and model of the removed
equipment. No problem, as fortunately, I found a photo of the data
plate of the removed unit with the serial number written in magic
marker. That was satisfactory, we’re good to go.
I also asked what I needed to do on the acceptance flight, and they
referred me to a web page that said what airspace I needed to fly
in, and for at least 30 minutes, but nothing more specific. That web
page referenced AC 20-165B, which calls for an hour long flight, but
not as restrictive in the airspace. I called AOPA, and they said two
360s each direction, plus flying over a fixed point N/S and E/W. OK,
can do, we’re good to go.

Advice on Older RV Avionics Full Upgrade ...ansonfogel in Salt
Oh Wise Wizards of the VAF - I am a recent buyer of Tom Whelen's
1994 built RV4, a wonderful machine, well maintained, low hour,
impeccably built - in 1994. All steam, barely useful GPS, etc - and
showing signs of wear on the various electrical systems. So. I've
been obsessively researching (I am an engineer by training, so get
ready for a nerdy post):
I am fairly settled, and have quotes from Stein, for a single 10"
G3X based EFIS and mostly garmin parts including full ADSB in/out,
etc. My mission is VFR only, but I do fly often cross country for
work and personal travel. I fly in mountains a lot - based in Utah,
fly over CO Rockies at lot, etc. Space inside is a big limiting
factor in RV4's, and I'd love to delete the lower between legs stack
altogether. I fly by myself 75% of the time, with a passenger 25%. I
do light aerobatics but no competition - I mostly fly to and from
places in the west, XC. I cruise often at 12-14K feet, and my
airfields are mostly at least 4K feet ASL.
Plan to is install all electric, no more steam. Garmin G3x, w/XM
(like the better resolution and reliability over ADSB only), engine
monitor, GPS20 adsb complaint GPS, heated pitot/AOA replace, Garmin
pitch and roll servos using on board G3X controls (only, plane has
no autopilot or electric trim now), GTR20 remote com, integrate
existing King Com as Com2, Garmin GTR45 ADBS source/out/transcvr,
and G5 backup instrument with its own battery. Update/move analog
switching, alternator, battery - but keep those analog breakers and
switches, no solid state new control box for that (?) in a new
My debates are a few:
