Friday morning I scooted out to 52F
for a gas run up the Gainesville and back. Smooth
flight, $3.50 gas and viz straight out of the
brochure. Great flight - logged .6 - been too
long. RV performed flawlessly. The plan was
at Mr. Frosty (built in '54) in Denton with some
of the usual suspects.
Chris Pratt (RV-8) and I were texting and firming
up plans - shaping up to be a good lunch. When I
landed back at 52F I had a voice mail from Susie
saying we had 1” of water in the master bedroom
closet. New plan...
home fast, turned off the water to the house and all
hands on deck moving clothes and drawers out into
other rooms. Started
cutting out wet sheetrock. Rob (RV-8) and Randy
(RV-8) showed up around lunch time to rub it
in help find the leak. It took us a
bit, but the leak was found and plans were made for
the fix. It turned out to be caused during the
initial install over three decades earlier. The
'plumber' made a partial cut on a pipe, then decided
to leave the pipe a little longer and instead made
the actual cut further down. This partial cut, maybe
because of metal stresses, maybe from molecules from
the steel cutting blade being pressed into the
copper (dissimilar metals), corroded, weakened,
leaked and finally sprung a big honkin' jet sometime
during the night last Thursday. Took ~35
years. Pics in the link below...

bomb went off. Mr. Frosty next week maybe.

My dad passed on this day in 1999, and New Years
Eve understandably has never been the same.
I'm usually a little down this time of year because
of it, but on a drive up to Whataburger Sunday
morning I caught myself smiling, because I know he
would have really enjoyed complaining about this
water leak. He would have wanted to tear that
plumber a new one the size of Texas.
The closet is
almost dry as of press time. Time to clean up
the cut lines, start measuring and go to Lowes for
supplies. I'm going to put a removable panel
where I can get back there easier next time if I
ever need to.
While moving stuff out of the
closet, Susie came across a family document that we
thought was lost. When Tate was a small boy he
saw a frog that had been run over in the street in
front of our house. He asked Susie if he could
write a note to the other frogs. He put the
note below on the ground out near the street.
Finding that note for our family was like finding
the Magna Carta. Our 'Huffman Prairie Moment'
of the Great Water Leak of '18. For the last
15 years or so whenever someone would see a frog, at
least one family member could be counted on to blurt
out, "Dear Frogs and Toads...". Finding
this made the year.

Revised RV-8 Sub-Cowl ...tuft testing update
I tufted our RV-8 and flew with the modified sub
cowl a few days ago. The point of the sub cowl is to
reduce the exit opening to raise CHT and oil
temperature, which it has. (Our XP360 was running a
bit too cool). The below video indicates the exit
flow is not perfect but better than the first
Here is a video of the first attempt. Note the
large lip on the trailing edge of the opening which

Please read if converting from Fixed pitch to Constant Speed prop
In the process of changing from a fixed pitched prop
to a constant speed prop, I have ran into one major
issue. Hoping to have a thread that folks can view
and use to make a decision before heading down this
If you are a moderator, please consider making this
a sticky. It will save someone thousands of dollars
and many weeks of troubleshooting and backtracking.
STOP!!!! before you even think about doing this
conversion, some very costly advice i had to learn
on my own (even though the info is out on VAF on
various threads if you look around).
All engine cases are not crated equal. Make sure you
know what type of case you have and how it has been
configured. Just because you have a hallow crank
does not mean you can convert to constant speed by
adding a governor and associated line, gasket, pad,
Some engine cases have a port/hole on the left
engine case half. (Example picture, not my engine)
RV-9 Performance PIREP ...Bill R.
My O-360 powered -9 taildragger spinning a fixed
pitch Catto prop will cruise right at 175 knots at
8,000 feet density altitude at 75% power.
On Christmas day I spent some time exploring the
lower end of the performance spectrum.
Within 900' from the end of a runway on a no wind
60°F day, not my touchdown point, I was able to land
and take off again. That was land, stop, raise the
flaps, adjust the trim and take off in less than 900
feet. Since I floated past the end of the runway, I
absolutely believe Van's numbers.
On that same flight I thought I would see what my
optimal extended range speed would be.
It turns out that 40% power gives me 135 knots
running while burning 4.8 GPH LoP.
This works out to 28 GPH gives me a range of over

Prop Help Requested ...Dewey Clawson
I recently purchased a 2012 RV10, 390 hrs, TTSMOH,
TT airframe. IO540, Blended Airfoil Hartzell CS, MT
I flew it home from TX, 7hrs, and Tue flew about an
hour. Wed I took a puppy to just S of Albany, NY (2
hrs) and another guy took her on to her furever home
in Maine. I took off on the return leg and was level
at 8,000 IFR, just on top of the clag, about 63%
power, 22inches, 2100rpm, or so and about to lean
and the rpm ran away. 2700rom.
Yanked the throttle back, could not change the rpm
with the prop lever. Prop had gone to flat pitch.
Next thing I looked at was oil press. All OK.
Started immediate turn back toward lower ground (was
over the Catskills) and better wx and said the magic
word....EMERGENCY. Landed at Kingston-Ulster
Found the only mechanic on the field. He was in the
middle of 2 week vacation but came in to help me. We
talked to Penn Yan and to NE Propeller Service. They
gave us some ideas to look at.
1. Linkage was connected and worked OK ran eng and
prop was not controllable.
2. Moved the prop by hand and each blade moved OK.
rotate blades. OK
3. Stick a paper clip in the zirk fittings on the
prop. Only grease in there.. OK
4. Removed the oil filter and inspected it for metal
shavings. Looked OK. Front main bearing hasn't spun
and blocked the oil passage.
5. Removed prop governor and drove 3 hours to New
England Prop Service. They tested the governor and
it checks OK.
Drove home 10 hours.
Out of ideas.

Complete RV8 Panel for Sale ...friend of mine. Cleanest shop
I've ever seen
It is time for an upgrade and I would like to
sell my current panel as a complete unit. This will
include all of the harnesses, probes, etc. that are
currently installed. When I remove the panel I will
label all of the wiring so it will easier to
reinstall in your project. The Tru Trak Vision AP
and pitch servo was purchased at OSH 2018 and
installed in August. Everything is in good working
order and is a great option for someone looking at
an inexpensive and complete panel for your project.
This will include everything you see in the center
panel as well as the EI Oil Pressure and Temp that
is located in the right side panel. I also have a
new-in-the-box Garmin 660 and AirGizmo mount that I
was going to install where the 496 is currently
before I decided do to a more extensive upgrade.
I have taken 50% of the cost of the equipment to
come up with an asking price of $7,200 or $7,800
with the Aera 660 and Airgizmo mount.
The panel is located at Propwash Airport (16X) and I
can deliver it to you via Cessna 180 if within a
reasonable distance. I never need an excuse to
Please call or email me directly if you are
interested and I will provide a list of the

Prop De-lamination RV-6 Update / Solved ...Brooks
Alright boys and girls,
Flew the pacesetter without a spinner today (no
backplate). Honestly, I think it's almost the same
speed with the little "test pilot" wind triangle I
did. Regardless, climbs amazingly and ran smooth
enough by just leaving my existing dynamic balancing
washers where they were.
GRT configuration ...Jeremy 7A
I'm in the middle of an avionics upgrade and
can't seem to find the info I'm looking for to
configure my GRT Sport EX/Horizon EX.
I used to have a Garmin 300xl, Sl30 and the internal
GPS for the GRT. The nav choices under the softkeys
were listed as GPS1, GPS2 and Nav. The 300xl was GPS
I now have an Avidyne IFD440, SL30 and GRT internal
GPS. I've checked and the appropriate serial
counters are counting, the system seems to be aware
of the sl30 but the only annunciated Nav choices are
"440-1" and GPS2.
I know there are a number of ways of configuring it
and I would like to hear from folks what their
preferred setups are for IFR work and how I do it.
I'm sure I'm missing something simple here but I
would love to at least see "440-1" and "SL30" or "Nav"
as a second choice. I really want to know what Nav
sources I'm following!
I've got an email and phone call in to GRT but it's

Tip RE Removing Fuel Caps
Brake Bleeder Kit ...N319BC
I think I’ve found the Holy Grail in Brake
bleeder kits all for less
than $10. While at Lowes I stumbled
across this 2 Liter (0.5 gallon) Pressure sprayer
for $5.88 in the home and garden section. While
there, I went and bought 10 feet of 3/8 OD tubing
(1/4” ID) ~ $3.00
Connect the 3/8” tubing (about 2 feet) to the
sprayer and the other end to about 2 feet of ¼”
“static” line tubing. Wire tie them together to
prevent any leaks. Connect the static line ¼” tube
to the zerk brake fitting (AKA bleeder valve) and
you have bleeder kit that works with virtually NO
spillage. Just a couple of drops when removing the
tube from the brake (zerk fitting). I filled up the
Left Main on my 10 in less than 5 minutes.
I cannot find a listing at the Lowes website but
here is the manufactures info.

Salvage Project... new kit or rebuild? ...BruceMe
I have a RV4 half-built wing/emp I found for very
reasonable nearby. Then I found a salvage also
cheap... The wing is obvious, just finish it. The
fuselage is teetering on the edge of rebuild/re-kit.
I purchased it cause it probably has enough
fitting and bits and bobs to make it worth the ask.
I'd take this down to bulkheads. Straighten them all
out then re-skin, maybe $2500 in aluminum. Or for
$5,0000 I can buy a fuselage kit from Vans and start
from scratch. I'm not sure which to do. Which way
would you go and why?
Listen to this Stein Guy...he knows what he’s talking about
Q: (Turner B.) I have wiring harness from
stein with all the wires for the EGT/CHT probes
(brown wire). My Garmin engine sensor kit has all
the probes which are terminated with staggered ring
terminals with small screws.
I need to make connections between the brown wires
and these probes - what are the acceptable/common
methods for doing this? I've been using butt splices
sealed with shrink tube for connecting other
miscellaneous wires (in some cases of course devices
have their own terminal plugs i.e. PMAG).
Ring Terminals are fine and used by many (we keep
them in stock and obviously sell them too). Some
folks also have/and do use spades, butt splices,
knife splices and other methods. It is nice to
be able to remove them and swap if need be as
previously mentioned, so we prefer "non-permanent"
options like the small ring terminals.
And Speaking of Stein....

video library on his site? You should.

Otis Holt Chimes In on the Mechanical Fuel Pump Vapor-lock Issue Thread
The bypass valve aspect of the regulator should
serve as a check valve against this. You might
consider replacing the regulator with a simpler
fixed bypass valve nominally set to 25-30psi. The
metering valve should tolerate a range of pressures.
Airflow performance systems rely entirely on a
high-quality bypass valves and don’t require
regulators. The hexagonal brass colored bodies shown
in this photo of the dual pump system I’m installing
are bypass valves that feed back into the return
lines.(I’m eliminating the engine drive pump, thus
redundant electric pumps).
Wheel Fairing Question: Waxing screws ...Ken Stockman
I am at the point of putting on the wheel
fairings where the plans tell you to used floxed
epoxy around the areas where the fairings attach
with screws. One is supposed to coat the screws with
candle wax so they don't set up in the epoxy.
Question: Do I try to get as thin of a coat of wax
on the screws as possible? Not sure what the best
approach is. Or is there an alternative to wax?
Also the metal brackets are supposed to be covered
with plastic tape. I assume that electrical tape is
the best approach here.
Chasing the issue - low fuel pressure on takeoff ...John C
The low fuel pressure on takeoff appears to be a
design issue related to cavitation at the engine
driven fuel pump. Controlling the pressure at the
engine driven fuel pump appears to be the most
The problem is not consistent. At times, the
pressure at takeoff does not drop below 4-4.5 psi.
At other times, the pressure can drop into the low
2s or even near 1 psi.
Often, I can lower the nose and pull back to 4000
rpm, see a pressure recovery, power up and continue
The two solutions offered prior were to use a blend
of 100LL or just accept the low pressure if there is
no engine falter. To me, neither is acceptable. I
prefer, and the engine was designed for mo-gas.
Hopefully, the slightly higher rated Facet pump will
boost the pressure at the engine driven pump to
prevent the pump cavitation, if that is the issue.
The problem may only appear on the RV-12, at least
according to two of the Rotax dealers and
information from user’s groups or operators of other
designs. Thus, it would appear to be a design issue
related to the RV-12.
PRESSURE DROP IN SYSTEM:
There are several contributors to the lessening of
the pressure at the engine driven pump.
Static pressure with the Facet pump: 3 psi
Pressure with engine and Facet pump running: 5.5 psi
Pull the c/b: 5.2 psi
At higher rpms such as runup: 3.5-4.5 psi, sometimes
drops to 3 psi, rarely to 2 psi.
At takeoff, the pressure often drops to 1-2 psi.
Van's, Rotax and others suggested instrumentation or
installation issues as the source of the indicated
or actual low pressure problem.
1. Bad engine driven fuel pump: changed engine
driven fuel pump, same problem. Result, both engine
driven fuel pumps are ok.
2. Unusual blockages restricting flow: Using the
Facet pump only, the static pressure was 3.0 psi.
The pressure transducer is on the right forward side
of the firewall, near the top. Flow was 33 gph at
the engine driven fuel pump; 20 gph at the fuel
pressure transducer; and 1.4 gph at the end of the
fuel return line (you should also see 1.5 gph flow
on the Skyview.). I did not check the flow to each
carburetor as they only need 2.5 gph to each.
Result, no unusual blockages.
3. Bad fuel pressure sensor: Static pressure about 3
psi and drops to 1-2 psi on takeoff. A new sensor
was added and the results were the same. Dynon
pressure was compared to a mechanical gauge on the
ground, at takeoff and in flight (see later post for
mechanical installation). The mechanical gauge was
consistently about 0.1-0.2 psi less than the Dynon
sensor. Result: Dynon sensor is accurate to
demonstrate that the large pressure drop was real.
The system design also contributes to the pressure
loss. It appears that the typical overall system
loss is about 1.5 to 2.0 psi attributed to
increasing fuel flow when and the rpm is increased
from idle to 4000-5000 rpm (see above).
4. Contributing to the overall loss:
Long fuel line runs: 140 inches of 3/8 tube. The
Facet pump in the middle confuses the issue for me.
Numerous components/fittings: 4 components and 10
Six 90-degree bends (plus two 45-degree bends)
5. Column pressure due to column height from tank to
engine driven pump: (this is included in the overall
from full tank: 8 inches or 0.2 psi
from empty tank: 21 inches or 0.5 psi
Takeoff dynamics further contribute to the pressure
6. Increasing column height due to pitching up is
added to the overall system loss.
10 degrees pitch at 72 inches: 12.5-inch column
increase or 0.3 psi
7. longitudinal acceleration adds to the overall
0.2 Gs longitudinal acceleration calculated from
change in ground speed. With a 90-inch horizontal
column, the 0.2 G longitudinal acceleration =
18-inch column increase or 0.45 psi pressure loss
during acceleraton and/or initial climb.
The total loss is about 2.5-3.0 psi at takeoff. The
portion of pressure loss due to the takeoff appears
to be about 0.7-0.8 psi and may be the reason that
the problem typically appears during the takeoff and
initial climb phase of flight. The pressure drop at
takeoff lessens the pressure at the engine driven
fuel pump. Perhaps that is the primary trigger for
cavitation at the engine driven fuel pump.
The higher rated Facet pump may fully offset the

Canopy Issue After Paint (Ugh) ...bkervaski
Yikes! (the pic makes it look a lot worse than it
This happened at the paint shop already during reassembly,
the painter fixed it perfect. Happened again this morning.
Been about 15 flights in between.
The best I can tell the is that I left the canopy up on it's
pins, which keeps it at an angle, on Saturday. Came out
today to fly, lifted the canopy, and "pop", this happened. I
think what has happened is that it was in a position where
the front thin aluminum was touching *every so slightly* and
it got a little tacky (temperature change?) and held it in
place just long enough for the lip to catch the seal. The
more it raised, the more it started bending and digging in.
Already talked with the painter, he can fix it again. Evoke

Prop delamination, RV-6 stuck on cross country, HELP!
Felix (custom) wood prop that is meticulously inspected
got me from Denver to Doylstown, PA. Upon inspecting the
prop today a few days before heading home, I realised there
are several points of what appear to be delamination that
may have occurred from the humidity and temperature changes

G loading on RV6...
Reading the discussion about g limits on the RV
(let's use an RV6 as the baseline).
Let's say the plane is loaded to its aerobatic
weight of 1390.
The airplane has a 180 lbs pilot and 16 gallons of
fuel (all in the left tank)
Now the plane is loaded again to its aerobatic
weight of 1390.
The airplane has a 100 lbs pilot and 29.3 gallons of
fuel (all in the left tank).
Even though the airplane is loaded to the same
weight, does condition 2 (100 lbs pilot) put less
bending moment on the wing spar than condition 1
(1800 lbs pilot)?

And here they are. All done with the exception of

and the fact that it has two trim tabs made these
much more challenging than the RV-7 elevators. Glad

Motivational Quote ...Jerry Morris
Again, I have to stand back and realize just how
fortunate we are that Dick VanGrunsven designed this
wonderful group of airplanes.
I departed Chino California yesterday at 6:40
pacific time, pointed the nose east. One leg to Dona
Ana NM., just west of El Paso, next leg to Conroe,
Tx. just north of Houston, and one long leg to Saint
Simons Island Ga. and I’m home 12 hours
later. Literally, coast to coast. 1,890
So if you get a little frustrated, remember this
post. RV’s truly are a little magic carpet that
literally open up the whole country to us.
Now, get back to work.

ADSB save - or near enough for me ...Greg Niehues
ADSB save - or near enough for me
This morning I was flying my 9A into KMDD headed to
work, talking to Midland approach. They pointed out
traffic at my 1 o'clock opposite direction 5 miles
and handed me to advisory frequency. I saw the
traffic on ADSB but not visually, he was on a
parallel course about 1 mile to my right coming at
me, about 900 below as I was descending into KMDD.
He was not talking to approach and he was not on
KMDD advisory frequency.
I was still descending and getting within 300' of
his altitude and had not found him visually yet -
when I noticed on the ADSB screen he had taken a
90-degree right hand turn and was heading directly
for me, less than a mile, just as the Dynon
squawk-box hollered "Traffic!". I gave up the visual
search and pulled about 2.5 positive G to quickly
add several hundred feet between us. I finally
caught sight of him just as he crossed under me, we
would have had less than 100 yards separation if I
had maintained my original course and descent.
I don't know any way to have avoided this, since the
other pilot was not talking on the local frequency
nor to approach (he was in Class E airspace, so not
required) but having the ability to SEE him
electronically certainly gave me the situational
awareness to avoid a close encounter and possibly
worse. I did not have a tail number on my screen so
the other aircraft was not ADSB-equipped.

Converting a GTX-327 from Parallel to Serial Altitude Encoding
I decided to join the 21st Century and change the
altitude encoding inputs to my Garmin GTX-327
transponder from parallel to serial, driven by my
Dynon D-6. Sadly, six years ago when I had the
harness made up for the GTX-327, I didn't instruct
the shop to add the shielded pair(?) for the RS-232
serial encoder input to Pin 19. My first plan was to
extract the unused wire going to pin (socket,
actually) from Pin 20, and move it over to 19. No
matter how hard I tried, I was unable to get the pin
extractor in the hole, so I gave up and moved on to
Plan B. I begged a socket from the FBO and added a
The wiring diagrams for both the GTX-327 and Dynon
D-6 were unclear, especially regarding the shield
grounds. The Garmin just showed a ground symbol for
the shield, but didn't specify case ground, power
ground, or signal ground. I chose signal ground but,
in retrospect, I don't think it made any difference.
The Garmin schematic didn't show a "return" or
"common" wire for the RS-232, so I guess the ground
was it. I still don't know if Gamin intended a
shielded pair or a single shielded wire for the
RS-232 IN. The Dynon schematic didn't show shielded
wire at all, but there actually was a shielded pair
coming out of the harness. It contained a "return"
line for the RS-232. The wire color in the manual
was incorrect, but I figured out which wire was
which with my Fluke.
Without going into the boring details, I connected
the Encoder Out wire from the Dynon to Pin 19 of the
GTX-327, and all the shields and the second RS-232
"return"? wire from the Dynon to Power Ground with
~8" #22 pigtails. I programmed the ALTENC setting on
the Dynon to "Format 4" for the GTX-327, and on the
transponder, set "RS-232 Input CHNL 1" to "Icarus"
per the manual. I was as surprised as anybody when
it actually worked. Now I guess I'll need to get
another transponder check in order to remain legal.
To work on the GTX-327 connector, it must be removed
from the backplate with a long, skinny, screwdriver
(two Phillips screws). Then the backshield clamp can
be removed and the shroud retracted, exposing the
back side of the DB-25 connector. Hint: The
backshield clamp can NOT be reinstalled with the
connector in place. Ask me how I know.
The two black wires are the "power ground" and
"signal ground". You can see they are spliced
together so apparently it doesn't make much
difference. (Ignore the tygon fuel vent passing
through the aluminum without a grommet. I'll put the
grommet back tomorrow.)
IFR for RV-4? ...Larry DeCamp
Q: Please tolerate my ignorance. I am
equipping an RV4 with G3x and all 2020 compiant
hardware. Panel space is limited but I thought it
would be wise to layout the Avionics “shelf” and
panel so IFR is an easy upgrade for the next owner
if desired. Garmin suggests a gtn 625 to compliment
the G3x because it is not certified IFR. It feels
logical to me that one panel (G3x style) wille
eventually be the solution.
Do you have any suggestions to satisfy the IFR
function with a G3x panel as a starting point ?
A: (Nived17) Ask away regarding Garmin IFR
installs. I'm adding a G5 as a backup in a week (it
will be installed where the airvent is in this
picture) and then the heated pitot in January
A: (Slice) I've been flying with this
setup for the last 18 months or so and very happy
with it. I also have a Stratus 2S and iPad mini that
I had used before the panel upgrade. So with that I
have 3 attitude and 4 nav sources(3 gps, 1 VOR/ILS)
with the iPad being totally independent. You could
get by with the G3X, a nav/com radio and a Stratus
and iPad. It's nice to be able to file /G when
needed though not to mention more and more GPS
approaches showing up all the time at smaller

acceptable at this specific place ? Moreover , there

Wing walks - a (better?) idea ...Dick Gossen RV-12
There are two problems with the original wing
walks: They're too small for my big feet and, the
rivets wear through the black anti-skid material
(unevenly and ugly-ly) There's a long thread about
this by Bob Noffs in here somewhere, where flush
rivets are discussed. Too much work!
So I addressed both issues as thus.
1. Wear-thru. I cut the anti-skid stuff into strips
to fill in between the rivet rows. Made nice rounded
corners, so they look and work great. It's been that
way for three years and 400 or so hours with no
visible wear or peeling at the edges. I suspect
that's partly because the rivet heads take much of
the abuse, while the anti-skid anti-skids!
2. Size. I ordered extra wing walk skins from Vans
and trimmed them to butt against the originals,
roughly doubling the useable area. Now I dont have
to worry about passengers with big shoes...and I can
sit my lard-..s comfortably on the walk while I'm
working on the panel or just fidlin' with the
Garmin, without "oil-canning" the wing skin.
Note in the picture the rivet pattern looks like
there are supporting half ribs under the added
skins, but there are none, of course, since I made
this mod after the wings were complete and
flying....and dented badly by an enthusiastic but
The unsupported double-skins are super strong and
support my 200+ lbs easily.
Note also I trimmed the new skins at the rear so as
to avoid drilling into the spar caps!
Just an idea....works for me
RV-9? What am I thinking? ...Rich (Keller, TX)
Howdy y’all. Hoping to get some sound feedback
and advice from the good folks here on VAF about
this crazy idea I have about building an airplane.
Like many that have come before me, I am embarking
on this journey having many personal reservations
about my ability to even complete such a project,
and am further consumed by anxiety and fear that
even if I should finish it, that my final product
might tarnish the reputation of the manufacturer,
and disgrace all the artists who have painstakingly
crafted so many of what I consider to be the most
beautiful aircraft ever built.
In speaking with other experts in the field (none of
whom have actually built an aircraft on their own)
the common advice I receive is that I should just
buy a plane that is already built, as it will save
me time, money, and possibly my marriage. Though
likely to be good advice, it is the process and the
challenge of building the plane, and the expectation
that I will be so intimately familiar with every
thread of its fiber that when it is completed it
will be part of me, that really has me so excited to
take on such an endeavor.
But my primary motivation for building the plane is
to share it with others...
Okay, that’s all a bunch of ****. I really want a
plane so I can fly up to Arkansas and Colorado to go
fishing. There’s no trout in Texas. I need one
that’s fast, sips fuel, and can land off pavement,
preferably as close to a fish as possible. And I
have to look good doing it. It can’t be big enough
to take everyone that wants to go, but big enough to
take a kid, or a wife, or a dog, or someone who will
buy ALL the beer when we get there. But most
importantly, it’s got to have room for a Yeti cooler
that I can fill with fish!
After months of careful consideration, and houndreds
of hours spent here researching, I have finally
decided to build the RV-9. I have exactly 1.9 hours
of tailwheel time about 17 years ago, so it seems
the only logical choice. After all, why not build a
plane that I don’t know how to fly when I don’t know
how to build a plane in the first place? Makes sense
My questions are very simple and probably will have
no answers of opposing opinions:
1. Should I get my head examined befor ordering the
2. I’m planning on ordering the IO-320 with a Catto
3-blade prop. 2nd choice would be the Sensenich GA
prop. I really would prefer to keep it simple and
light. Am I limiting myself significantly for flying
into high density altitude airports/grass strips by
avoiding a CS prop? Of the two I listed, would one
have any significant benefit to the other? I cannot
afford to leave any fish behind!
3. I don’t really intend on landing anywhere too
rough, but love flying on grass strips. I was
originally going to build a 9A, but have been
horrified by all the stories I’ve been hearing and
reading about with respect to coming to rest
inverted. Has this problem been rectified? Any
viable engineering solutions? I’ve finally come to
terms with learning to fly a taildragger however,
but any input would be appreciated as I would still
consider the 9A.
4. Eventually, I want to teach my kids how to fly my
plane. Anyone else have any experience teaching kids
in the 9? I can barely get these kids interested in
driving a car, so I certainly don’t want to
overwhelm them in a taildragger when maybe they
could get the spark in a 152.
5. Are there any RV groups in the DFW area? Would be
nice to meet some nice folks who have similar
interests. I could also use the technical and
motivational support and my wife would probably like
recommendations for a local mental heath provider!
Let the good times roll.

Don’t get marooned ...Aviaman
What are the likeliest reasons you will be forced
to stay somewhere overnight (not including WX)? IMO
the 2 biggest causes are flat tires and dead
batteries. Can we carry items that give us self
sufficiency, where we can fix things quickly?
My idea is to carry a spare wheel assembly, so that
no splitting of the existing wheel is required. That
greatly simplifies the fix. A jacking method is
still required. Jacking on a windy ramp is
problematic, so if you carry jacking items, you may
still need to move inside of an FBO hangar for an
hour. The jacking equipment might be too bulky to
carry, and the assistance of an FBO might be needed.
What about the battery? An external power port
allowing jump starting will fix the dead battery
problem. On my previous RV-6, I fashioned a welding
cable and connected it to the battery in the battery
box. It was protected with grommets and terminated
with a trailer connector. The cable was a few feet
long and kept coiled on the floor with a protective
boot to preclude a short. A mating cable was also
fashioned to connect to a jump starting battery
source. Any other ideas or better way to deal with
this, or other, out of town problems ?

Cold Progress ...Tdeman RV-7
It’s been cold out in the hangar, but I’ve tried
to keep the progress moving. I built a visqueen box
to try and keep some heat in, and some moisture out,
hence the change of backdrop! One benefit is it
reflects much more light from the sides.
Finally tackled the seat pans. Things not quite
being perfectly straight 90 degrees to each other in
this area made it difficult to bend single sheets to
fit everything for the lowered seat ribs… So a
3-piece seat pan was built because it was easy to
make it register well on all surfaces.

Update to Nigel's 'T/O Config Effect on T/O Distance' Thread ...Bill
Dust off this excellent and useful thread
have to belatedly say thanks to Nigel for this data.
I am finally getting some more accurate data for my
RV7 POH and want to see what was available.
I have 180 hp with the Hartzell composite - the wide
blade one. I tried the lift the tail on a cool day ,
34F, and got about 450 ft for lift off. The
G3X data was used to calculate the position and
speeds. VS defined the lift off point.
450' seems high compared to Vans (275) and my
estimated weight was 1480 lbs, so it was not heavy.
I could probably make a little more RPM on brakes
and certainly use the tail low lift off technique
for slightly reduced roll. Maybe higher tire
pressure will help too. Cold tires rolling drag
coefficient can not be good.
I really appreciate the detail Nigel has provided,
it will shorten the test work.
One snag is the accuracy of the WAAS gps data, but
way better than the next best and it is really easy.
One last thing, if anyone has governing equations to
make a definitive correction of TO roll and climb to
different temp, altitude conditions, please post or
send an email.
Control column installation and bearing stiffness (RV-14)
Scott - I owe you a beer. Just a light tap on the
side loosened it right up! It did take another
few hours of playing with shims to get it perfect
however I think it is worth it. Just as a side note
- I did remove the entire control rod and used a
bolt with washers directly on each bearing. With
this setup I was able to use my 24" socket extension
to tap directly onto the bearing. I did this on both
sides and it magically opened up. Hindsight: I
wouldn't prime between the bearing brackets, BoeLube
before installing the bearing into the bracket, and
squeeze slowly on each rivet before the final set.

the pant were anywhere within 3/16" of where they
needed to be to line up with the holes in the
bracket. I lay there on the floor beside the main
wheel and tried to wrap my head around any possible
explanation. A shift of the pant to align more of
the holes was physically impossible due to the size
of the existing cutouts for the tire and leg, as
well as the fixation imposed by the bolt in the axle
In the end, I re-drilled 5 of the holes using the
Christmas lights on a stick trick someone mentioned
here for back-lighting. That was a life saver of a
trick. I am unable to explain the misaligned holes,
being confident of the pains taken to realign
everything exactly as it was before, but I would
recommend an alternate technique: drilling the holes
in the brackets first, then installing and aligning
the pants, then back-lighting the holes and
marking/drilling the pants based on the light spot
as a reference. Aiming for an ink mark through the
semitransparent wheel pant into an angled bracket
ear introduces some considerable potential for
error, at least in my case.
I plan to follow the recommended procedure for final
fitment using 6-32 screws and mold release. This
will have to wait till after the kids and grandkids
come to visit this weekend. Family first!!!
One Other Thing (Bill)
I believe Scott's caution about the screws vs clecos
applies only to the common spring-type, which would
deform the pant unacceptably.
I realized too late after drilling the #36 holes
that, as a SilPruf window installation veteran, I
had a good supply of a cleco type that might just
avoid this issue - as well as the need to tap all
those temporary holes in the brackets. Probably
won't be able to use these now that the holes are 4
drill number sizes too large for them - my bad.
Might help someone else who has wing-nut clecos in
their shop, though.

colleges, sickness and the other priorities, it
seems to be taking forever to finish my elevators.
am building both at once. I am now working on the
trim tabs. The rest is done less the fairings.
Hopefully you will see another pic of some finished
So far the elevators have been the most time
consuming and brain teasing part of the build. The
way these go together requires some thinking to keep
it all going together correctly. Add in the
complexity of the riveted trailing edge, foam
ribs/pro-seal and trim tabs on both sides makes
these much more of a challenge than my RV-7's
Another thing I have noticed is that Van's has
really cut back on the hardware provided with this
kit compared to my 7. Seems like they sent enough
hardware to build 2 airplanes (rivets, nutplates,
pop-rivets) on my 7 but with this 10 I have been
very short on a few rivet sizes and have had just
enough of the pop rivets. They went from way too
much to just enough and in some cases not enough.
Somewhere in the middle would have been nice....
Good thing I have spare rivets on hand!
Check out my build blog for the details on my build.
Over 8,100 page views so far! Thanks for looking!

A Letter from a Former POW
Subject: Your Camp Howze story and pix
To Sarah Reveley
"I stumbled onto your pictures and story concerning
the German POW camp at Camp Howze. Thanks for
bringing back memories.
I was one of those POW’s at the camp from Mar 45 to
Spring of 46. There were 3 compounds for the
prisoners, all next to each other. Most of us worked
on area farms, I had the fortune of working at the
Camp Howze laundry plant. In the Spring of 46 we
were shipped home, which turned out to be a journey
to England where we had to work for another few
years as POW’s for the Brits.
In the mid 50’s, I with my family emigrated to the
US. I had opportunity to visit Camp Howze (or what
was left of it) in the early 70’s during a trip to
Dallas. At that time I met with and talked to a
farmer who had built his homestead where the camp
was located before. He told me that I was the first
and only former POW he knew of that ever came back.
Thanks again for your story and your pictures." -

ounces and I was able to make use of that dang flap skin
that I messed up during the wing build.

Clogged Injector? ...istrumit
Hello all -
A few minutes from landing on a flight a few weeks
ago, I felt a very, very subtle change in engine
vibration, so I had a quick look and noticed the CHT
on #3 cylinder (IO540) had risen about 15 degrees
and was suddenly the hottest cylinder (I was
descending at medium power).
I fiddled with mixture and nothing improved (or got
And i watched as the temperature continued to
gradually rise by about 5 degrees until I was within
range to reduce power and land, at which time it
fell back in line with the rest of the cylinders.
At no time did the cylinder actually fail to fire,
but it did seem 'unhealthy'.
I pulled the data from my monitor and I found that,
just after beginning my descent, #3 started to rise
and #4 started to fall, both abnormally (compared to
data from other flights).
I inspected the injectors for #3 and #4 and saw
nothing obviously wrong. I used cleaner on them
Test run was good. And I test flew it again today.
Everything seemed normal during test, until I saw
that #4 had gotten unusually cool again.
Landed..ran it up....tested the leaning
Took off again...all normal, but I decided to
postpone my 1.5 hour trip until I figure this out.
So, currently, I have a normal running engine that
seems to have fluctuating temperature previously in
3 and 4, but now, just #4.
I also tightened the intake on all cylinders (to
account for induction leaks).
Bottom line...I'm stumped.
The engine runs fine. Starts fine.
But, I want to understand this anomaly.

Pic request - Fairings-Etc tail fairing install on RV-7/8 ...Dave
Q: Fellow Fairings-Etc tail fairing
customers, would you share pictures of your fairing
installation, especially the lower fairings? I'm
particularly interested in how you attached the
lower fairing to the fuse and whether you installed
any fasteners to the underside of the HS.
......Any new info would be much appreciated!
Q: If loops, rolls, or spins are not
documented during phase 1, does that mean they are
not authorized in that plane? If so, can they be
added later, and how?
Any aerobatic maneuvers to be flown must first be
tested within phase I. You may place the aircraft
back into phase I for a minimum of 5 hours at any
time. This is listed in the operating
limitations issued for the aircraft. Depending
on when you op lims were issued, you may have to
have them amended. Earlier versions of op lims had
the option to be issued to allow or not allow
aerobatics. If you op lims state that aerobatics are
prohibited, then you must have them amended.
Trailing edge wedge countersinking ...Girraf
after a lot of research, I started to countersink my
Rudder trailing edge wedge yesterday morning (AEX
wedge). I had been struggling with how to reconcile
the fact that the hole I drilled through the wedge
(and skins) when match drilling was perpendicular to
the centerline of the wedge, yet the countersink
should be perpendicular to the face of the wedge on
each side. If using a pilot cutter in your
countersink cage, this will most certaily apply a
side load to the little pilot on the countersink
cutter. Sure enough, after 10 or so holes, I ended
up breaking the pilot off my bit. (#*@&!)
I recalled that on the my practice kit, I
countersunk the wedge using a speed deburring tool,
which is essentially a countersink cutter with no
pilot. Turns out you can create the necessary c'sink
with the deburr tool very effectively, if you apply
some elbow grease. I then decided to disasseble my
c'sink cage and mount the deburring bit in the
holder and free hand the process using a drill. If
your easy on the trigger and careful (check depth
often), you can make great countersinks and my end
result was fantastic. I did have to install the
wedge into the rudder twice and check for proper
nesting of dimples as some needed to go slightly
deeper but I was able to finish the job while I wait
for a new c'sink cutter to arrive (went with single
flute this time).
All this to say, don't be afraid to try something a

The Skew-T and extreme turbulence ...scottd
If you are not a Skew-T fanatic, you should be.
Here's an excellent example of what the Skew-T can
do for you. Take a look at this Skew-T analysis from
15Z in southeastern NC.
Notice at about 6,500 ft MSL, the winds are from
the southeast at 58 knots and then around 9,300
feet, they are from the southwest at 57 knots. This
is an excellent example of directional shear in the
wind aloft. The key though is the moist unstable
layer that starts just below 8,000 feet that enables
the air to mix. All of this coupled together is the
reason this pilot reported extreme turbulence at
8,000 feet MSL.

Is your 'other plane' a bush plane? ...a poll I started for Jaybird

document that I'm gathering signatures for to see if there
is interest, my friend Jay Pratt told me today another of

asked what I thought about a poll regarding people who own a

Here is the question:
you are building or fly an RV
you own an additional plane, is that additional plane (or
one of the additional planes if you own more) what would be
considered a 'bush plane'? A J-3 or a Champ would be an

A: (g3xpert) Page 28-4 of the Rev. AG

Note that the GNS 4XXW/5XXW units don't support an
external Go Around button like the GTN 6XX/7XX, but
you can still wire the TO/GA button into the GSU 73
to trigger TO and GA modes on the G3X.
You will have to manually activate the missed
approach on your GNS 430W just like you do now since
it doesn't support the remote button. The 430W will
still provide guidance and let you couple to the
missed approach just like a GTN after you activate

Dairy-Ashford Drive and the West Park Tollway, in
southwest Houston. Eagle’s Nest will supply the

RV-3 Brake Fluid Hemorrhage ...swjohnsey / oaklandaviator
Q: I am the proud new owner of an RV-3
#190/10190 N93JP. It has a brake fluid hemorrhage. I
still have brakes so it must be somewhere between
the firewall mounted reservoir and the master
cylinder on the right side. It has fuselage mounted
24 gallon fuel tank. Will I have to pull the fuel
tank to gain access to the brake line. What do I
need to replace it with? The current line is some
sort of plastic/nylon.
A: What an
interesting coincidence in that my wife's RV-3 just
had this exact problem. We would get to the airport
and a puddle of brake fluid would be under the
center of the plane dripping from the fuel vent. To
get behind the firewall required removing the upper
skin and windshield (hers is a slider), then remove
the fuel tank. Once that's out everything is easy to
see and work on. Hers had a loose tee fitting on the
back of the reservoir so we just resealed it and
tightened it up then bled the system.
To remove the tank, once the skin and windshield are
off, you'll need to drain the tank completely,
remove the vent line from the front of the tank
between it and the firewall, then remove the fuel
feed line at the bottom rear of the tank (unless you
have an inverted fuel system with a flop tube, which
we installed on my wife's plane. In this case the
fuel line is located at the front bottom of the tank
and will probably require you to lift the tank up
and have a helper loosen the line.) Tank should just
lift right out. To reinstall, loosen the tank straps
slightly to make it easier to get the screws started
on the upper skin. You'll have to sit in the seat
when it's all back together, reach under the tank,
and tighten them back up. They pull the tank up
against the skin.
Do any other needed maintenance under there while
the tank is out. It's not that hard, but I don't
like pulling it unless really necessary. There's
great access to everything up front with it out so
take the opportunity to look over everything really
well. It's a great time to rebuild or replace the
brake master cylinders, tidy up wiring, or install
any cool avionics. Very easy to get to everything.
Partial Alternator Fauilure at 245 Hours ...Colin RV-10
Thanks to this thread I have determined what is
wrong with my transponder, or battery, or VPX
Pro...nothing!!! The PP 60 amp alternator that was
standard in the RV-10 FWF kit had a partial failure.
For the last 6 months or so the Dynon transponder
would trip at random times during nearly every
flight. I thought it may have been because of a
software update that was done around the same time
that would cause the transponder to momentarily draw
more current than the 3 amp VPX circuit would allow.
I changed it to a 5 amp circuit and the problem
persisted. I brought up the VPX page on the AFS EFIS
and once saw 37 amps reported on the transponder
circuit, ridiculous considering the 20 awg power
wires would have become a fusible link at that point
but they were fine. With the engine running the
voltage was solid at 14.2 and the amps reading
looked normal giving me no reason to suspect the
Then my ETX1200 battery light started constantly
flashing. I would charge it on the ground, go flying
for a couple hours and by the time I got home the
light was flashing again. Obviously a problem with
the battery right? Not cool for a very expensive
battery that was under 2 years old.
So I pulled the battery and sent it to EarthX last
week, installed a PC680 so I wasn't grounded. The
next flight the problem with the transponder became
constant. I reset it and it would immediately trip.
I guess the EarthX battery was providing some
masking of the problem.
So then I found this thread. Today I removed the
fairly young Plane power alternator and took it to
an alternator shop. They tested it and it showed a
problem. They took it apart and found one stator
wire broken off that also took out a portion of the
rectifier. It is currently still at the shop and
they are trying to repair it. The stator is a uni-point
part and apparently difficult to find in the
There are no problems with the bearings. For a
background on my plane the prop was balanced to .03
IPS before first flight 2 years ago and was checked
at the same during the 2 subsequent annual
inspections (I have a smart avionics PB3 dynamic
balancer). The belt was also torqued properly so
neither of those were causes of this failure.
If the lifespan of a PP alternator is somewhere
around 200 hours I think I need to look for a
different product. Maybe an automotive unit would be
better since they would be easy to source just about
anywhere. The alternator shop showed me a 14757 that
is mentioned elsewhere in the forums but it is
larger and heavier than the PP. I'm open to other

Mountain SW Advice ...JD (RV-4)
Living in the
subject area, my advice is to fly early when the
lighting is best and the air is smoothest. Flying
over in the afternoon at 14k will cause you to miss
the sights and the beauty. With good, early morning
light, the colors come alive!
If not familiar with the effect of density altitude,
please brush up. Most of the ground in this area is
higher than the typical pilot cruises. Takeoff and
landing at 11,000' DA is different. Cruising at
8,000' and skimming the ground is unnerving if not
Watch the winds aloft at 18k. That will tell you how
rough it will be over the mountains. If the winds at
that altitude are high (40kts), expect rough.
Depending on what you want to see and do, the whole
area is a huge playground. Monument valley is neat
but, sadly, it is a tiny little place (when going
150 kts). Be sure to see Canyonlands, Bryce Canyon
(you can land at the airport and get a shuttle to
the park to walk the canyon trail), Comb Ridge,
Goosenecks, Capital Reef, Meteor Crater, Gila
Wilderness area, etc.
If I were flying CNM to PGA and the weather/winds
aloft are good, I'd fly west towards LRU to get
around White Sands to the south. Then head direct to
PGA or Monument Valley. This will take you over the
continental divide and some great sights. If you
want to see the lava flows and chain of craters,
head towards GNT. If you want to see Shiprock, LRU
direct to 5V5.
Another great option (for sights) is LRU to JTC (Springerville)
to SEZ (Sedona) and then to PGA. There are also some
really great backcountry strips available if looking
to camp or do that kind of sightseeing.
The only real problem is that this is a MASSIVE area
making it hard to see it all in one trip!

Brake Cylinder Problem
Q: I have a brake
cylinder that is leaking fluid inside the cockpit. I
removed all four cylinders and replaced the seals.
One of the cylinders is still leaking fluid. I think
this one was responsible for the main leak that I
had initially. Should I just buy a new master
cylinder. It is a Cleveland 10-30 master cylinder.
Or is there something else that I can do to stop the
leak besides the rubber seals that I already
Replacing the seals/o-rings should fix the leak. If
not, it is likely corroded and may need to be
When rebuilding the Cleveland 10-30 master cylinders
in my 6 I discovered the piston shafts worn where
the top seal makes contact, which was the cause of
my leaks. After polishing out the surface
irregularities on the piston shaft and installing
new seals they remain leak-free after two years.

Magic Carpet Is Airborne! ...Chris RV-12
After several weeks hoping
for the weather to improve my MagicCarpet RV-12 S/N 120832
has finally airborne. The maiden flight was flawlessly and
very successful. A tiny bit of heavy wing on the left side,
which will be adjusted with the upcoming flights. Beside
that she flies very nicely, well balanced and yet agile. The
outside view is simply superb. Max. speed. was 116kt TAS at
5500rpm at 5000' without the wheelpants.
The plane features a single Dynon 1000 Touch with analog
backup instruments for altitude and airspeed. A Power FLARM
traffic avoidance system and a dual port 5V USB charger. The
interior consists of confor foam leather seats by Flightline
Interior with custom stiches, sidewalls and all carpets.
It took me 4 years and a little over 2000h to complete her,
followed by 9 month for final assembly, exterior painting,
acceptance procedure and airworthyness certification.
Needless to say, that I am very proud to have finally took
her up in the sky.
At this point I would like to thank you all here at VAF for
your outstanding support. You are truly awesome.

Great Couple of Weekends! ...SeanB
11-18 Today was a big
day!!! Tracey (my bride) was awesome, once again, and
volunteered to help me get the plane on its gear. I already
had the tailwheel on. We got the engine hoist and a giant
tow strap to the front of the plane. I weaved it thru the
engine mount. Gotta admit, I was a little nervous as we
started getting airborne off the fuselage dolly. Things
could roll or pitch. Tracey jumped in and helped stabilize
the front of the plane from rolling. I tried getting the
first gear on, but I still had slight interference from the
fuselage. Emergency action with the Dremmel took care of
that. I was able to get the gear slipped into the socket,
then get the bolt started. "Wahooo", exclaimed Tracey! I
raced to the other side and had no interference. The leg
went into place and again with the bolt. Another, "Wahoo"!
We took a minute to look at
the sight of things and smiled. The back of the plane was
still on the dolly, so I went back and easily lifted the aft
fuselage. Tracey rolled the dolly, then the plane was on all
three wheels for the first time ever! I was so excited and
thankful Tracey was there for help and to share in the
excitement. Couldn't have done it without her. I was so
excited, I rolled the plane outside for many more looks.

track. G3X showed 39kts of wind at 2,500' so
those maneuvers that didn't require me to stay over
one spot understandably had some drift (like the
steep turns right and left done first).
Climbed up to 7,500' out of class B for the 1,080*
spiral down at idle. That was 'fun' with the
40+kt wind up top. Staying over one spot
required a quick turn with many seconds after almost
wings level. More detail in the zoom in.
The jagged track is usually when the plane is near
60* of bank.
Fun to do and to
track for later critiquing. The RV-6 (compared
to a C172) makes these maneuvers more challenging,
IMHO, but I got my instrument ticket in it so I'm
confident. To those unaware, some of the
maneuvers require the wind to be from a specific
direction at start. The wind vector on the G3X
makes this a non-event. Now if there was a
wizard in it that would calculate the pivotal
altitude for the eights-on-pylon! <wink>.

supportive in this project and never hesitate to
come to the garage to give a helping hand. Second, I
like to thank VANs team for creating such wonderful
kit that is just a joy to build, they have outdone
themselves. Lastly, I like to thank Doug and this
great community for always providing good support,

Win in First Air Race 1 China Cup China Cup
November 21, 2018 - Steve Senegal, EAA 478025, held
off Tim Cone, EAA 374465, in a dramatic finish in the
gold final at the Air Race 1 China Cup in Wuhan City, China.
Steve, flying his Arnold AR-6 Endeavor, clocked speeds of
more than 230 mph during the final.
The Air Race 1 China Cup, which took place November 16-18,
was the first air race to be held in China. Air Race 1 CEO
Jeff Zaltman said it would be far from the last one.
“Bringing air racing to China has been a major triumph and
the public have fallen in love with Air Race 1,” Jeff said.
“I would like to thank our Chinese partners that have helped
to make this happen and we look forward to working with them
again in the future. Air racing in China is here to stay.”
Tim had an early lead in the gold final in his Cassutt What
Airplane Honey, which must be a familiar feeling after he
won the Air Race 1 World Cup event in Thailand last year.
Tim ended with a speed of 230.539 mph, while Steve won out
with a speed of 233.637 mph. Philip Goforth placed third in
the gold final, and Steve Tumlin took home first-place
honors in the silver final."
Steve and Slick (Tim) are also Vans
RV 8 drivers.

11/25/18 Update ...j-red RV-8
The night we moved the fuselage, a couple of
friends came over and helped fit up the wings with
some tapered hardware store bolts. These same guys
helped me do the wings on the 6a. Based on that
experience, they were prepared for a
several-hour-long ordeal. This was nothing like what
they expected. Maybe 5 minutes per side, and they
were temporarily hung.
Over a couple of days, the tanks were attached and
fuel lines fitted.
The next major job was to check for incidence and
sweep. Once the fuselage was levelled, 4 plumb bobs
took care of the latter, and a piece of angle
clamped to a 4' level made checking incidence a
piece of cake.

Too Deep! Counter sinking the Rudder trailing edge ...hubbardr1
After getting the rudder ready for priming I went
ahead and moved forward to the elevator. The
elevator trailing edge wedges went much smoother and
much more uniform. So I decided to take a second
look at the rudder wedge and I'm worried. I'm pretty
sure I overdrilled the rudder trailing edge wedge
counter sinks too deep.
The top wedge in these photos is the rudder wedge.
Bottom is from an elevator. The rudder depth from
top of rivet head to the top of the skin is about
double that of the elevator. :/
can also see where I pulled the drill press too hard
and slightly deformed the wedge edge. I'm worried
once riveted, the trailing edge will resemble a
missouri road vs something nice flat and and
So what are my options? I've contemplated re-doing
the rudder wedge but I've already dimpled the rudder
skins. Seems impossible to get the hole alignment
right now that its dimpled.
Anyone out there redo the rudder wedge? Successful?

Got some coworkers over with promises of beer,
and we mounted the wings last week. Today I
checked rigging. Incidence is a hair high
(bubble is touching the forward mark) but it's even
on both sides, all the way out (no twist).
Edge distances are good. Triangulation is dead
on to 1/32". Both wings are swept
forward 3/8" at the tip. The flaps touch the
bottom skin perfectly. Close enough for
government work! Now there's a couple days'

Tip-up Lift Strut Test
There has been a lot of talk about adding quick
release for the lift struts on a tip-up, should the
canopy need to be jettisoned.
I just ordered a new set of lift struts for my
canopy, thus I will so have a pair that we can
I was thinking of taking a flat foot sheet of
plywood approximately the size of the canopy and
hinging it at the bottom, attaching the struts 1/3
of the way from the top and securing them on a
trailer and see at what speed they pull out.
I suppose I could make the sheet half the width and
mount the strut in the vertical center of the sheet
so I can run two tests.
Dan, you are much better at this than me, do you or
any others have a suggestion for running this test?
My theory is that the struts will pull apart at a
fairly low speed.

Hello, I'm new to the forum and a 100 hour
private pilot; I've been looking at buying a used
RV12. I went and flew one a few hours this weekend
to get some transition training. I really enjoyed
the plane and the handling, especially the 3-4 gph
at 100+kts! When I talked to the experienced 15K
hour instructor he advised against one for anything
except local around the patch flights. I'd really
like to think it could be used for trips from Socal
to Northern CA, AZ and even Utah, New Mexico...he
thought with the big mountains everywhere that would
be dangerous and such a light plane would not be a
good choice except on the most perfect of days.
Obviously I'd pick the best weather I could, but to
be honest, he made me nervous that I'm being naive
about the realities of light sport x-country
capabilities. Would love to get some thoughts from
those of you that have more experience. Thank you!

Haven't updated progress in awhile in my own

I was pretty much running out of things to do
before drilling the gear legs and messing with seat
tracks and such. By that I mean, lacking an avionics
suite, there wasn't much more to do during the
easy-access stage where the fuse is on a rolling
dolly down close to the floor.
Time to spit on my hands, rub them together,
hoist the Jolly Roger and slit a few throats.
And sweat a few bullets.

After much pondering I decided there was no need
to make a sawhorse just for this job. The EAA

34" and will certainly hold the weight. Tail resting

hoist, up she goes! Slowly. Ever so slowly. Check
everything twice, three times... The fuse canoe
hasn't been off this trolley since I inspected the

Review: The Hartzell Composite Propellor on my RV-7A
...Otis Holt RV-7A
Not long after I purchased
my flying 7A in October of 2017, I took the plunge
and ordered a Hartzell Composite propellor and
aluminum spinner through Van’s. The decision to buy
was downright scary, as several pleas for opinions
and experiences here on VAF went unanswered, and
searches of prior posts turned up very little info.
Were pilots having bad experiences they were not
revealing? Was I making an expensive mistake?
The blades have an incredibly large surface area
and chord widths from 3.5” at the squared-off tip to
over 8” at the widest point. Long after I’d paid, my
old friend and propeller guru Jack Norris told me
that classical propellor theory would suggest nasty
tip vortices, and I wondered if my plain-vanilla
180HP, 8.5 compression Lycoming clone would be able
to pull it, or if top speed would be severely
limited. I’ll jump ahead and declare a resounding
YES to the first and NO to the second. Evidently the
lack of info on VAF was mainly due to very few of
these being installed on RV’s because of the higher

First flight of 120910 ...RV-12 UK
Pleased to report the first flight today of G-DOUZ in the
careful hands of UK LAA inspector and fellow RV12 builder
Jerry Parr. Following Jerry's initial 30 minute solo flight
I joined him for a second flight of just over 2 hours and 12
landings. Hopefully another 2.5 hours tomorrow to complete
the LAA test schedule.
A 39 month build and the first dual G3X Touch 12 in the U.K.
First flight completed.
On a lunch run today, the Tach. ticked over 2,000 hrs.
This may not seem like that big a deal, but the engine in
the RV-8 that I just bought last year is a hopped up Lycon
modification of an O-360A1A that had fuel injection added as
well as ceramic coated, high compression (10:1) pistons.
Many people told the previous owner, that flew it for 15+
years, that this particular engine would never get to TBO,
primarily because of the high compression pistons. In fact,
it will make more than TBO since I plan to fly it for
another 2 years before having the engine overhauled.
It runs extremely well, has good compression on all
cylinders and is not making any metal. The only gripe is
that oil consumption is slowly creeping up, and has been
over the past several years. I am currently at about 1 quart
every 4 or so hours. This is what will probably lead to the
decision to pull the trigger on an overhaul eventually.

Alternator problem - here we go again ...74-07
Ok, I have a Plane Power 60 amp alternator. It works fine
for a while then, it doesn't. We've run out all of the
wiring and checked the belt. We looked at the plug and
tugged on the wire. All good. We've done this three or four
times. Every time, after we check everything over, it works
again for a flight or two then, we get a low voltage warning
and sure enough, we're running on the battery (12.3 volts
and decreasing). As a last resort, I have purchased a new
plug, pins and seals. Today, while removing the old plug, I
noticed that the white wire (unused) was in the correct
location (#1) but the aircraft red wire was in the center
pin location (#2) rather than the #3 position as depicted in
the Plane Power drawing. The jumper was installed correctly
between #2 and #3. Could this possibly make any difference?
Can't see how it could since the red wire is connected to
the jumper and would be connected to both pin locations in

New member of the 'Sinker Club' (carb floats) ...pstraub
After about 125 hours on my RV-12, I was
beginning to think I would be one of the lucky few
without carb float problems....I was wrong! Doing my
night currency last week, I noticed the smell of
fuel in my cabin for the first time. Also, my idle
had been gradually getting rougher. After shutting
down for the night, I opened the oil tank door on
the top cowl and the fuel smell was very strong.
With a flashlight, I could see standing fuel in the
drip tray! I removed the top cowl and dropped the
float bowl.....sure enough, the floats were mostly
submerged. After letting them dry, I weighed the
pair and they were 11.4 grams. I then checked the
left carb floats, they were not as bad yet, but
still over weight at 9.5 grams. I just ordered 2
pair of the latest PN, 861188. Wow, $300!! I guess I
have a new and expensive 'consumable', this engine
is 1.5 years old with 125 hours. Based on everything
I have read, I am not confident that the new floats
will last any longer. Maybe it's the ethanol in this
California fuel. I just wanted to add my experience

EarthX battery pirep ...William Slaughter
purchased an EarthX ETX900 for my rear battery RV-8 for the
substantial weight savings and increased electrical capacity
over the Odessey 680 I'd previously selected. Since the
ETX900s terminals are on the centerline of the battery, you
have to install the cables before installing the hold-down
clamp. I of course have an insulating cover for the positive
terminal, which I had believed was sufficient. But it was
not. While wriggling the holddown and bolts into place, I
managed to momentarily short the battery to ground. This
resulted in an impressive flash and bang, and a noticeable
divot in the hold down bolt. Removing the holddown bracket
and bolts, I noticed that the top part of the battery was
quite warm to the touch, but that seemed logical after the
energy dump which had just taken place. I immediately set to
work thoroughly insulating the holddown bolt (the bottom of
the bracket was already insulated), and when finished,
crawled back in to re-install, but the battery was still
just as warm, just short of hot. I removed it from the plane
and called EarthX. They diagnosed it as an internal short in
the damaged BMS, and suggested I fully discharge it and send
it back. They suggested a resistive load such as a light. I
brought the battery home, checked the voltage (12.9) and
attached a 55 watt driving light. In spite of being wounded,
the battery drove that light for quite a few hours. I
returned the battery, EarthX repaired (probably just
replaced it actually) it at no charge, and sent it back.
My take homes:
Despite being wounded, the battery did not rupture or catch
fire, and continued to provide useful voltage for a
substantial period of time.
The customer service at EarthX is just outstanding - I made
it clear that this incident was entirely my fault.
I have no qualms about putting the battery back in.
Now before someone replies that a regular AGM battery would
have been unharmed by this momentary short, that is
undoubtedly true, but beside the point. You can make a
similar argument against a carbon composite prop because you
can't just file out a small ding like you can on an aluminum
prop. "There ain't no such thing as a free lunch."

line between the halves gets progressively wider (open) as
it proceeds forward to the spinner. Here some pics of where
I am now;
And a solution: (DanH)
A common question in my PM inbox is how to extend the
edge of a cowl that has been trimmed a little too short. The
subject has been covered very well in the past, but perhaps
a dedicated thread will search better.
There are two methods. A small extension (like 1/8", maybe
3/16") can be done with a flox/epoxy mix. A longer extension
is done with multiple plies of glass fabric.
Both methods are based on a scarf joint. Block sand the
scarf with coarse grit paper. The scarf should be 3x wider
than the glass thickness, minimum. The wider it gets (5x,
10x thickness) the stronger the joint becomes.
A hold and approach...jpowell13
Still needed a hold and one more approach by the end of
the month. Ceilings were about 1,000' yesterday, but there
was an icing forecast near but not exactly in the space I
would be flying. The wind was gusting to about 20 knots and
there was a turbulence forecast near but not in the space I
would be flying. I hung around the airport waiting for
better conditions, but decided to write it off and try again
Ceilings were about 1000' and climbing this morning with an
icing airmet from the surface. Winds were about 8kts. By
late morning the icing airmet was lifted and surface temps
were at 41F. There were no precip reflections. Overcast
extended from 1400' up to 2900'. A 172 took off and flew an
approach while I was prepping the plane with no apparent
I filed "local IFR" and flew a hold and an RNAV approach to
landing. The temp at 3000' was 32F, and I saw mist in the
clouds, but no ice on the aircraft. I may have cut it close
with respect to icing, but with the ceiling at 1400' the
airport in Marginal VFR conditions and with flat terrain and
no tall antennae where I would be filing, I reasoned I could
let down below the ceiling in a pinch. It worked out well
today. Should I have flown or stayed on the ground? John

Boiling fuel/vapor lock..an engineering question...Mark33
So as we all know, boiling fuel, caused by either heat or
decreased vapor pressure at higher altitudes is not a good
thing and causes vapor lock. I know that different types of
fuel (Avgas VS. Mogas) have different temperatures and vapor
pressures at which it boils, but for this discussion let's
take that variable out of the equation and pretend that
regardless of the type, that it all boils at the same
temperature and vapor pressure. So:
1. Does anyone know how much pressure is required to
overcome this boiling point and to keep the fuel in its
2. As the temperature or altitude increases, does it take
additional pressure to keep the fuel in its liquid state? If
so, is there a simple formula to calculate that variable?

NACA Duct on RV-4 Cowl ...acam37
I was going to do the same thing. I saw it on a -4 at a
local fly in and thought it looked really good. But after
cutting the hole and checking where the hose would enter
through the side skin, the throttle/mixture cables were
right in the way. So there was no way it would work on the
left side with my setup. I glassed the hole up and abandoned
The Gremlin is Back...
Well, my gremlin is back after three trouble free hours.
Here are the symptoms:
1. CHT, EGT and OIL temps spike high. Left EGT spikes more
than others at about every 2-3 seconds.
2. Spikes are not synchronized.
3. At low temperature the indications are reasonable. That
is before start, they reflect ambient temperature and
respond normally (I sprayed Freon on them and observed a
drop in temperature below ambient.
4. Disconnecting the CHT leads drives the indication low
leading me to believe this is not a connector issue.
5. Oil pressure, fuel pressure, tachometer and fuel flow are
stable and unaffected.
6. Today during ground runs I got an voice alert “EMF Low”
alert, but main bus voltage was stable at 13,8 VDC.
Any ideas from the brain trust? Tomorrow I’m going to talk
to Dynon.I suspect the D180 May have an issue.
Wingtip repair what glass fibre cloth do I need?
Unfortunately I damaged the wingtip on my RV8 and I wondered
what glass cloth I should order for the repair and what
resin and hardener you guys use? West System?
I'd like to add a bit of glass to at the top of the wing and
add a strip across the seam inside the wing to add strength.
Where would you get it from? And any tips to do the repair
My Second IAC Contest
I was asked to do a short write-up of my experience so it
might inspire others to get into aerobatics with their RVs.
So here it is:
I did my first contest 6 months ago and it was a great
learning experience. Since then I have been too busy and
have not practiced the Primary Sequence much (in fact not at
all except at 2 practice days with the new chapter I joined
last month). I have been spending a little time with the
Sportsman sequence and just playing around with point rolls,
vertical rolls, reverse cubans, humpties, etc. Just having
Flying this contest was a last minute decision and I did not
show up in time for practice, so I went into my first round
without even seeing the box. On top of that, there were
issues with my paperwork and I was not cleared to fly
literally until the last minute. That left me very flustered
and stressed out and my score showed it - 66%.
I did better the next day with 77% and 75% flights, but I
was still disappointed because I felt I could fly better,
but just couldn't perform when it mattered. However, due to
the low turn-out, I still ended up with a first place
finish, despite my mediocre overall score.
I also ended up being given the "Grassroots Achievement
Award" for having the highest score in any category with a
low HP airplane (defined as less than 180hp). I also was one
of two pilots in all categories with no outs and no zeros in
all three rounds. So overall it was a great weekend, despite
me not performing my best. I learned a lot and met some
great people and gained valuable experience.
I plan to compete in Sportsman next year and excited to see
the 2019 Known sequence. I know I won't have as good a
chance at placing well (compared to if I stayed in Primary),
but I'm ok with that.
When at a contest, I'll do my absolute best, but in general
I'm not as competitive as some guys. I love aerobatics for
the pure joy of expression in 3 dimensions. And I enjoy
doing higher level maneuvers, even if it's not done to
perfection to win a trophy. So having fun and meeting great
pilots and always improving is what's more important to me.
But of course bringing home the goodies once in a while
isn't bad either.
A big thanks to all you guys who were supportive and
motivated me to get into this. It's been great!
Oh, and the other cool thing about this contest was to see
the look on everyone's faces when at the end of the banquet,
well after dark, I told them I'm flying home. No one else
could do that b/c their acro mounts were day VFR-only. I
once showed up to a practice day with my wife in the back
and unloaded a bunch of luggage onto the ramp. We were going
on a trip after the practice day! Gotta love the versatility
of an RV!
Hope to see more RVs join the fun!

Air Cleaner Box (FAB) K&N Cracking and rubbing
I see a ton of posts on this and various fixes. I took
off an old, and cracked FAB that had a metal plate on it
with a huge gap between the filter and the housing, and
built a new box and added support where the old one had
cracked. Within 100 hours, it had completely eaten through
the new bottom. My question is: Is there supposed to be ANY
contact between the lower cowl and the air cleaner box via
the baffle material? On BOTH assemblies, the thick plate
that mounts to the performance airflow section of the
throttle body has also cracked on the forward left bolt
area. I obviously have something WAY wrong. I've only had
the plane for a couple hundred hours. 815 hours on airframe.
Whats the fix?
Avionics Margins PIREP ...Stein from SteinAir
I don't have much to add other than to say the reputable
shops mentioned here I consider colleagues are fine folks (Aerotronics,
Approach, Walt, etc..). With the aforementioned folks
specifically, we all actually do business back and forth
with each other so I know what you can trust from whom. The
"cheapest" vendors are not on that list.
Most people don't realize that with Avionics (and many
things aviation) and unlike furniture, jewelry, or even cars
- there isn't much margin to start with. Anyone hoping to
find a 25% discount or difference in price between different
dealers is in for a huge awakening. The reality is that most
avionics and electronics now start out with a gross margin
to the dealers of high single or low double digit percent
numbers at best. That is why you see some folks charging you
extra to even use a CC, etc.. I've had/have people call me
assuming there are huge margins to begin with and insist on
a 30% discount. I have to tell them that when they find that
let me know, and I'll start buying supplies from them!
There are folks that will sell somewhat cheaper than others,
but you'll never find anyone that is 25 or 30% less than
someone else, because it's just not there to begin with.
That means that on an entire purchase of avionics you're
looking at very small differences (percentage wise) and why
we try to add value in other areas. The business model where
the only value you add is being the low bidder isn't what
we're all about.
As an aside, we do a fair bit of regular business re-wiring
items / harnesses that folks already purchased once
Just my 2 cents as usual.

$24 replacement battery for my 4.2-yr old iPhone 6 Plus,
then drove out to the airport to get a pic of the new brake
lines (thanks Monk!). New pads, lines and an overhaul of the
master brake cylinders that were needing some attention (Monk
had some O rings). Helped him move some planes around
before the cold, cold Wx arrives Tue (27*F forecast for am -
cold for us). By then it was time to get back on the
computer. No flying. Some shivering. A taco for lunch.
Productive morning. Hope warmer where you are...
11/12/18 Update ...j-red
Big day. Had a local auto towing service come
over and help me move the fuselage to the hangar.
This was the third time I've used these guys,
although it was this particular driver's first time
to carry a plane. He was pretty stunned to say the
least Took quite a few pictures to show his buddies.
$125 later, she made it to her new home at the

than rigging up a trailer myself.
First time I've been able to step back and get some
good full-scale pictures of it.
RV IAC Aerobatic Competition Standings - 2018... It's a wrap!
Congratulations to Brian Pfam who scored a first
place finish in the final IAC competition of the
season. Brian is the sole RV pilot competing in the
Primary category this year and expects to move up to
the Sportsman level in 2019.
I just returned from the IAC Fall Board meeting
where we reviewed the proposed KNOWN sequences for
2019. We returned the three lower category KNOWNs to
the Known Sequence Committee for a re-write. We
decided that there was no reason to change the
PRIMARY sequence as it worked well in 2018. There
may be some who think we should change the PRIMARY
sequence every year but the Board feels that PRIMARY
is just an introduction to competition and pilots
should move up to SPORTSMAN after a year in PRIMARY.
We sent the SPORTSMAN sequence back to the committee
because there were a couple of figures which would
have been difficult to fly by those without inverted
systems. (FYI: The policy guidance to the Known
Sequence Committee states that... "Proposed Primary
and power Sportsman Known sequences shall be flyable
by aircraft without inverted fuel or oil systems, in
the class of 115 hp Citabrias")
We sent the INTERMEDIATE sequence back to the
committee with instructions to omit snap rolls from
the KNOWN sequence. (Once again, the policy guidance
to the committee states that... "Proposed power
Intermediate Known sequences shall be flyable by
aircraft in the class of the 150 hp Decathlon.")
Many Decathlon aircraft have sustained damage to
fuel tanks as a result of doing snap rolls. However,
there is still the likelihood of encountering snap
rolls in INTERMEDIATE unknown sequences!
I think this is all good news for the RV aerobatic
group. There are no barriers to RV competition at
the SPORTSMAN level and those without inverted
systems have an equal chance of emerging victorious.
All it takes is practice, practice, practice! The
2019 competition season will be here before you know
it. Get ready!

Personal IFR Limits ...Ed Wishchmeyer PIREP
I very much agree with Rob's basic tenets. Other
factors to add in:
* Cumulus clouds give a very rough ride in the
RV-9A. If the height from cloud base to top is more
than 3 or 4 thousand feet, I avoid them;
* Instead of 500 foot overcast below, I prefer
1,000. Over known flat, open land, maybe lower, but
even Iowa has swatches for forest that would be
really bad if your first glance was at 500 feet;
* As for approach minimums -- you **** well better
be able to fly an approach to minimums!! Weather
does change en route. The difference is whether you
plan a flight where you anticipate flying to
* For me, inflight fatigue can be an issue, so time
of day, overall energy level, etc are factors;
* Since my canopy doesn't seal well, rain is a
* Another way at looking at go/no-go decisions is to
count the number of challenges on the flight:
turbulence, crosswinds, solid IFR vs on top or in
and out, ATC environment, airspace restrictions,
what happens if the autopilot dies, etc. Too many
total challenges on the flight, or too many
challenges at once are reasons to reconsider whether
to go or not. (And it's also real challenging to
have the autopilot die when you're busy fussing with
the automation and have low situational awareness
because of the automation...)
Y'all be careful out there!

the string ran past the center of the rest of the
tooling holes, then clamped it in place.

Veterans Day (Observed)
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 international 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 remodeled 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
[ed. In 1954, the word
“Armistice” was replaced with “Veterans” as a way to
formally include all Veterans of all American wars

Passing of RV6 pioneer
I want to let the RV community know about the
passing of an early RV6 builder/pilot in the
Colorado, Mas Yosida, N93MY.
Mas passed away quietly today after a lengthy
illness and was known as one of the RV pioneers in
the Denver area starting in the early 1990’s. Mas
has a long history as an aviation enthusiast having
owned a Luscome, C152, Mooney, Bonanza, but couldn’t
say enough good things about flying his RV6 since
No plans yet for services but I can post the
information here once I receive additional
information. Our thoughts and prayers are with Mas’s
Wing Attach 5/8 Distance ...Zazoos RV-6
Working on the right wing. Per the plumb bob it
is swept forward 1 inch.
The wing rear spar is fully seated and touching the
fuselage. The fuselage rear spar forward piece of
the fork is touching the wing rib.
I marked my 5/8 distance grid on both pieces. The
inside 5/8 distance on the fuselage is measured from
where the two forks mate an become a solid spar.
The inside 5/8 on the wing rear spar is measured
from the root rib flange.
1. Since the both spars obviously continue in there
respective directions can the inside 5/8 distance be
somewhat ignored? Otherwise as you can see in my
grid layout I really do not have the room to remove
any materials (especially on the wing rear spar).
2. If I'm correct that the inside edge distance can
be ignored, is there a good ratio as to how much
material to remove to get close to a 1 inch movement
at the wing tip?
Newbie Here ...Mike Singer
I am new to the build scene and have some questions
that might sound dumb... I am very interested in
building a plane but it all seems a bit
overwhelming. I ordered the toolbox kit to see what
skills are required to assemble something small
before investing a considerable amount of time and
$$. The kit has a few terms I am unfamiliar with. Is
there anything in writing or videos that someone can
refer to while learning the skills needed to
complete a build. Cleco, Deburr, Dimple, are just a
few that I spent some time researching but couldn't
get clear answers on.

Personal IFR Limts ...jpowell13 PIREP
Flew 5 practice approaches in my 6A today in IFR
This thread is really good for sharing IFR
experience. Brad said he flies practice approaches
in actual IFR in his 6A if it's allowed by his
My personal minimums are higher than his, so, it's
taken a long time for the stars to align, but I did
I needed 6 approaches and a hold, and me and the
plane were ready. It was low IFR this morning, with
a VFR legal alternate within about 100 miles. By 2pm
the ceiling had lifted to about 1000'. It was a
solid overcast. This seemed like conditions I could
safely deal with so I filed "local IFR" at BTR and
When I took off it was about 3pm, and the sky seemed
to be clearing. I was actually afraid that I might
not be able to log the approaches, but by the time I
got "on top" I saw no holes in the overcast. I hand
flew 3 ILS's while I was fresh and then let the
autopilot and 400W take over.
After the forth approach, I noticed I was breaking
out at about 500', and the light was dimming
surprisingly fast. I began to get that feeling
you've heard about. You know, "I wish I was down
there and not up here." So, I informed approach that
I'd be landing after the 5th approach.
By the time I got back below that layer, the runway
lights were on, and I think I could have
legitimately logged a night landing.
I'd have been a lot safer taking off at noon even
though the ceiling was a little lower then.
Departing late in the day in late fall just doesn't
leave enough daylight for going to an alternate if
you have to.
That's the point of my newly added minimum
requirement. "Have enough daylight to get to the
alternate and make an approach and landing."
Status Report 7A ...jcarne
Well I have changed gears a bit but I'm still

Gel-filled Mount Update ...DanH
Quick follow up...
The gel-filled inserts probably failed due to
overload, a case of excessive deflection of the
mounts due to load and age. Sag in shear allows the
middle of the gel bag to get pinched against the ID
of the inboard steel rings molded into the
doughnuts, and when that happens, compression or
tension displacement would tend to peel back the
ends of the rubber bag.
I suspect the Lord J-9613-40 mounts seen here are
just too soft for a 390 with a metal Hartzell on a
sport plane, the result being a lot of sag in
only 800 hours. Examine application listings which
include Vans, and you'll see the same isolator
spec'ed for a 320 with a Catto, and a 360 angle
valve with a metal BA. The engine difference is as
much as 50 lbs, and the prop difference might add 50
more. The prop center of mass is roughly 28 inches
forward of a set of mounts spaced 10 vertically
inches apart, so there is a force multiplier too.
The fun starts when trying to select an isolator
with slightly increased capacity. None of the three
aviation isolator manufacturers publish aviation
mount catalogs with technical data, notably shear
and compression ratings (lbs per inch). They do
publish good data catalogs for hundreds and hundreds
of industrial isolators, for every imaginable
application except aviation mounts. Go
Lord has the data, but the only way to get it is to
identify a particular isolator part number, then ask
someone in product support. They won't recommend a
specific mount, but will shotgun a few suggestions
and state the stiffness values when asked. There is
no practical way for a customer to simply select an
isolator from a list, based on engineering values.

Thank you both for the input. I was able to

RV-7A Rebuild ...Europe
As most of you know, I am currently building my RV-7
(RV7ForMe Build Log) and I have slowly been working
on my wings. But I have not posted much of an update
since the summer. There is a reason for this.
A buddy of mine has purchased a about to be finished
RV-7A. Meaning, the builder wanted to sell before he
finished the aircraft. Because of the 51% rule the
builder finished the kit with my buddies wishes in
terms of avionics and it all was well until first
flight. I am not interested in talking about why
this was a good or a bad decision. I am just filling
you guys in as to why the current owner doesn't have
any building experience.
On first flight there was a problem that caused an
engine stoppage. A forced landing on a field caused
the dreaded flip of the airplane after the nose gear
dug in... Yes there was the anti splat mod but the
gear just bent at a different location with the same
result. The good news is nobody was hurt.
The poor guy wants nothing more than to fix his new
plane but couldn't find anyone who had time to do
it. So he decided to tackle this himself. The
problem is that as all of you fellow builders know.
There is steep learning curve for all of us learning
the techniques. And this is where I come in. Not
sure how this came about but I was asked to assist
and most importantly teach him a little bit what I
have learned. Yes, I know I don't have all the
skills required here either. I am just building
wings but I am sure we can figure this out with
enough patience and research.
So I have moved my entire treasury of tools to his
shop and we have started to learn how to shoot and
buck rivets, how to use a squeezer, how to deburr,
how to drill, dimple and so on and so forth... Not
sure if I just happen to be a good teacher or he
just happens to be a natural but he is very talented
and is highly motivated!
I will be semi documenting these repairs here as I
thought this might be interesting to some of you as
well. Let me know...?
This also means that I will stopping building my own
wings for a few months because I simply don't have
the time to build at 2 places. I see this as an
opportunity to learn a few things for my own
airplane and I am still in college and don't have
the money for the Fuselage/engine etc anyway.

Flight training in ELSA. IS IT ALLOWED?
Q: I am on the verge of buying a RV12 ELSA
for the purpose of teaching my daughter to fly. I am
a sport pilot instructor.
Yesterday I read that the FAA has, or is about to,
release a NPRM to allow flight training in ELSA .
1. Can I give my daughter flight training leading to
her Sport Pilot airplane certificate?
2. If so, are there DPE’s who will give the check
ride in an ELSA?
A: As long as there is no
compensation to you for use of the airplane,
there is no problem in doing what you want to do.
Specific limitations are spelled out in the
operating limitations that are part of the 8130-7

You could receive compensation as a flight
instructor while giving training though.

for use of the aircraft (charging rental fees), and
more specifically, for aircraft types were there are
no SLSA examples for flight schools to use. An
example would be 2 seat ultralights that were
originally converted to ELSA's during the transition

Flap Bracket Rivet Technique: .....RV-14E
It's possible with a mushroom set, but it's tough
to do. When I caused a dent in that area, I tried
using a 12" long backrivet set on the manufactured
head to clear the flap bracket, yet caused another
dent. I put those rivet sets aside in favor of
I used a longer flush rivet set when I did my bottom
skins. This is a 5.5" flush set with a 5/8" surface
obtained used from Yardstore. They don't appear to
carry it any more, but it looks like Brown Tool has
the 5.5" flush set. Yardstore also 3.5" and 7.5"
long flush sets. The latter is probably too short as
it may not fully clear the bracket.

Moving a plane into a Mode C Veil, cheapest solution for Transponder and
Q: I'm buying my first plane and I have
found a plane I like, but it is located in an area
where it has never needed a transponder. Full
disclosure it is experimental, but not an RV. I am
just posting here because 90% of the valuable
information Google finds me on experimentals
(especially avionics) is from this forum.
My question is, if I do the install, what is the
cheapest solution for a transponder and ADS-B on a
plane that never had either?
A: (Mel) Cheap
is not always economical. Do your research. I
went with Trig. I've had Trig in 2 airplanes over
quite a few years and very happy with their system.
Complete ADS-B out including TT22 (Mode S
transponder), TN72 (ADS-B compliant GPS), and TA70
(GPS antenna). All for about $2400.
(Gary S.) Others have mentioned the Trig and I
agree it is a good value. I am planning on
using the Appareo-Stratus as I feel it is the BEST
for my RV-6. Everything in ONE box. Easier for me to
retrofit into a flying airplane. I will either buy
from Stein or RST sometime in the next few months.
I plan to abandon my Grey Code encoder and use the
serial port from my Garmin G5 as my altitude source.

Why Garmin Pathways Can Be Off-Center
"...synthetic vision is heading based (aligned with
the nose of the aircraft) since it is meant to give
you the same picture that you see out the front
window of the aircraft.
When you are flying with a crosswind, the nose of
the aircraft can be significantly misaligned with
the flight path marker which is showing you "where
the aircraft is going".
Since the track of the aircraft is aligned with the
course line, not the nose of the aircraft, you will
frequently see the flight path marker and pathway
boxes (if you use them) off the center of the
display when the CDI is centered."
Help me figure out a noise ...Brantel
So a few weeks ago I was on a nice smooth solo
flight and I started noticing a noise that I am not
used to hearing.
The noise sounds sort of like a high pitched whine
similar to alternator noise.
First I have ruled out the alternator. I can hear it
without the headsets on. I have also turned off the
alternator in flight and the noise remains.
On several flights after first noticing it, I
noticed that the volume of this noise appeared to
change on different flights. Weird....
So on my last flight I accidently discovered that
the noise volume is directly related to how much I
open the cabin heat flapper thingy.
If it is closed, the noise almost goes completely
If I open it, it increases in volume up to 100%
volume when the gets to about 50% open.
If I open the door more than 50% it starts to reduce
the volume of the noise.
One theory I have is that it is some sort of air
flow noise that is causing something to resonate and
the different volume is due to the changes in
airflow thru my heat system. (standard Van's with a
Robbin's Wings heat muff and a standard stainless
heat valve that dumps to the lower cowl when closed)
Another theory is that the angle of the heat valve
door is reflecting the noise to my ears when at the
proper angle making it sound louder at a certain
Any ideas on what the source of the noise could be?
For context: I have a mechanical fuel pump, 2 Pmags,
and a PCU5000X prop governor on my accessory case
and that is it. The engine is a bone stock narrow
deck carbed O-360.

short update regarding 2018 honor system donations.
Historically the amount of donations sent in determine
whether our family makes or loses money for the year. So far
(as of 11/3)
1,139 people were nice enough to donate approximately
$21K after taxes (out of the 26,122 VAF Forum accounts and
~30,000 unregistered ‘lurkers’ that regularly visit).
We haven’t broken even yet this year, so I’m starting to get a
little antsy in the pantsy. We are servicing our debt, but
we’d like to save a little for the golden years, so as we
stare down the final two months of 2018 I hope you don’t
mind if I take a moment today to remind those regular
readers who haven’t donated this year to please consider
doing it. You can use
a credit card and be done in around two minutes.

Intercylinder baffle grommet (ICB) ...pazmanyflyer
I'm looking to wrap up my hoses for my IO-360-M1B and I
have the Lyco ICB and the specified MS35489-20X grommet
(from parts catalog) and TS Flightline -4 fuel hose
installed. As you can see I have a 1/2" hose in a 3/4"
grommet hole. I'm sure this will whistle pretty good as well
as rob me of cooling air. Gooping it up with RTV is sloppy
and lazy and not what I want to see. Anyone have a part
number for the grommet that works with the -4 hose such as
the one shown?
Thanks in advance.
How much should I insure my aircraft for? ...VAF Advertiser
This question can be a little tricky. The best way to
determine the hull value is to consider what you would pay
for an aircraft similar to yours in its current state. There
can be serious consequences if the aircraft is not insured
at a proper value. Some examples are listed below:
Underinsuring: Let’s say your aircraft is worth $100,000 and
you insure it for $60,000. Then you have a prop-strike and
some other damage totaling $50,000. This would be a
completely repairable situation, however the insurance
company would rather total out the aircraft, pay you the
$60,000 check, and then sell your aircraft. There is a
chance that you could purchase your aircraft back from the
insurance company with the intention of repairing it
yourself however that wouldn’t leave you with enough claim
money to make the necessary repairs. (And most insurance
companies do not guarantee the first right of refusal)
Over insuring: Now let’s say your aircraft is worth $100,000
and you insure it for $150,000. Then you have a prop-strike
and have significant other damage totaling $90,000. Although
you would think your aircraft is totaled and have no desire
to fix the pile of scrap, it’s in the insurance companies
best interest to write you check for $90,000 to fix it.
Because that is more cost effective than paying you the
$150,000 check. This particular scenario could also make it
much harder to sell the aircraft down the road.
Insurance is meant to put you back financially where you
were before the incident happened without bettering
yourself. We cannot decide an amount for you so take a look
at what some similar models are selling for to give you a
good idea of your aircraft’s worth.

Fail mode? ...tim2542
Can anyone tell me the fail mode seen in this bearing?
This is a friends 0-200A Continental, relatively low hours
on field overhaul. The pic is the #2 bearing, #3 looks
similar but better, #1 looks relatively normal with a little
debris damage, nothing serious. The engine was disassembled
looking for a low oil pressure issue. Pretty sure this is
it, but this damage does not look like lack of oil pressure
or debris damage. I’m only guessing but it looks like
corrosion or some kind of plating failure. The tin babbit is
all gone on this one, and much of the copper. The crank
looks decent, probably will clean up with polish only.
Information from the previous overhaul is sketchy, not even
sure the bearings were replaced.
Some Avionics Shelf Ideas
I fabricated a shelf and some rails. Sadly, don't have
pics of it installed ... basically this is just inside the
glove box opening.
Great place to put stuff if you aren't going to have a glove
box and don't anticipate accessing whatever you're going put
there much, if at all. I put my SkyRadar DX there on a
"shelf" made of angle much like bkervaski:
Leaking fuel vent line in tailcone ...John C
I started smelling fuel during power back after takeoff
or when I opened the canopy while taxiing on the ground. In
flight, opening the heat vent or the side vents quickly
cleared the smell. The usual sources, such as carberator
bowl gasket or spitting fuel out the carburetor vent line
were clean and dry.
Finally checked the fuel tank vent line aft of the bulkhead.
Found where the fuel had been collecting. Notice the
tightness of the small vent line. It had shrunk a
substantial amount as slack in the line was gone.

RV-10 vs Piper Comanche 260-B ...Ivan Kristensen

saw it for the first time, at the Orillia, ON

looks great with the paint job I put on it in the

For the guys already flying, are any of you
having high CHT issues? Yesterday was about 59

helpers who both have 7s and high CHT issues thought
I must have some reading errors to be that low and I
don't recall anyone with a 14 posting about high CHT
issues. I was flying close to WOT and full rich as
these were the first flights. Can I solicit some
real world CHT numbers from you guys please?

Experimental kit airplane in europe ...
Hi, im new here. nice forum! i wanted to ask a few
questions on experimental kits i have. Ive been
doing some online research without success.
Im looking to own an airplane and my mission is to
tour europe. im looking to do this at 140-150 kts in
a 4 seater airplane
Im eu citizen and i have a spanish PPL EASA.
Because of the nature of my job i tend to move
within EASA . Ive been living in uk for 2.5yrs and
now ive been in Germany for 6 months.
I dont know where i might relocate in the future
ive looked at Arrows and Mooneys buy its hard to
find something good that you dont have to rebuild
the engine after purchase.
lately ive being looking at the experimental scene,
specially the Vans RV10 and Sling 4 TSI
Also because one of my life dreams and goals would
be to build an airplane.
Regarding regulations, what are those in Europe?
If i buy a RV10 or sling 4 kit, (or quickbuild
possibly) build it, and register it in spain/germany/uk
Can i fly internationally within EASA?
Can i fly night time?
Can i fly IFR?
Can i fly outside EASA?
What are the benefits regarding maintenance? is the
owner/pilot able to conduct its own maintenance?
(one of the mayor benefits of experimental in EEUU)
What other limitations are there to know?

Bruce Bohannon Training PIREP
Outstanding training by Bruce Bohannon
I am in the process of buying a really nice RV8
(hopefully if all goes well I will close by the end
of the week). I needed some transition training and
Bruce was recommended. I have only about 3 hours of
tail wheel, Beaver, Otter and a Cub all about an
Some background on me, not to brag on myself as I
feel a bit of it was timing on my part, but to
qualify my remarks on Bruce.
I began flight school in the T-34C as a young naval
aviator to be, went to the T-45C, then flew
Harriers. I had a boat deployment, dirt deployment,
racked up the quals and went on to be an instructor
at the RAG. From there I went to Naval Test Pilot
School; prior to starting TPS I got some training
from PIT USAF IPs in the T-38, and some T6 training
from the Navy. At TPS I got to fly things from a
mig15 to a super hornet, some tail draggers,
gliders, helos, warbirds, etc. By far some of the
best training I had was at TPS, we got to go touch
airplanes and really learn about aero, stuff that
wasn't typically taught in a text book or a lecture
hall. Went on to test the F-35; trained by some very
experienced test pilots. Got trained in the Legacy
and Super hornet by the Navy. I left the Marine
Corps early, went to American got trained and flew
the bus for a bit; then to the guard to fly RC-26,
received initial training on that from Flight Safety
and more from the guard; now I am a Flight Test
Captain at United typed in the Bus, 737, and 756.
So onto Bruce. I asked for transition training in
the RV8, but needed a tailwheel endorsement as well.
So today we started in his cub. Prior to that he
insisted on giving me extensive training on the
ground. Through the years of training, I knew to
approach with an open mind. When I pulled up I saw
on older gentlemen, looked like he might have been
someone who had been bailing hay or working on a
fence line. His place wasn't anything fancy (but I'd
love to have his setup with all planes included). I
got a handshake and welcome, then we walked into the
hangar and I really can't tell you when precisely
the ground school started. We started with some
casual conversation about my background, some other
things, and it was probably 3 to 5 minutes after
"class" had officially started before I realized he
was teaching me. All the things I have been taught
about how to instruct and getting folks attention,
get them interested he did so eloquently to me that
I didn't even notice he had done it and had my
undivided attention; it didn't even seem like he
tried. I kept wanting to open my backpack and get my
notebook out to write all the good information down,
but I wasn't willing to miss anything he was saying.
So onto what I think was 2.5-3 hours of ground
school; I know I showed up at 0900 and it was about
1300 when I left and we flew for an hour. I couldn't
tell you how long ground training actually was, it
felt like 30 minutes at best; again because I
couldn't stop listening I wanted more. Didn't feel
short because of content, just his delivery and
method of explaining things made sense. I am not the
expert in aviation; but I have had a bit of training
and experience, he was dead on accurate with his
theory and science. He explained things with physics
and aerodynamics, but in a way that was easy to
understood with no fluff. His instruction on how
things worked was as good if not better than some of
the ground training I had at Test Pilot School; far
superior to any other military or civilian ground
school I have had. Had he not told me his level of
education, based on his instruction I would have
assumed he had been to at least grad school,
instructed for most of his life, and been involved
with some higher level flight training program.
Onto the flight in the cub. He has a nice setup for
the cub. It was a bit of a gusty day. Instruction in
the plane was also outstanding. He used great
commands, kept my attention, gave correction when
needed, and pointed out when things were going well
to boost confidence. It wasn't long and things
clicked and were going well. I still had a tendency
to over correct some and work harder than I needed
to, as he told me I would. But he kept me improving
until we were done.
Debrief was also outstanding. Covered what I did
well, covered where I could improve. He also showed
how humble he was again, and took credit for my over
controlling and said he should have said some
different things in ground school.
Bruce is a very talented and smart man (though he
will never admit it), and well worth the trip
(luckily he is 45 minutes from me). I would have
taken vacation time, paid for the plane ticket and
hotel knowing what I know now. I haven't even got in
the 8 yet, plan is Wednesday, but I can tell already
this is probably going to be one of if not the best
place it get RV8 transition training.
I'll update as I get more training....

if its a 14A doesn't matter your opinion - sorry

indicator to onlookers .. maybe avoid somebody

back in 50 years if I still think I don't need a
A: It depends on your age and height. I am
75 and short. I need them. You will get older and
your passengers may already be there.
I designed the steps for my -6. They go straight out
behind the flaps, therefore they have no welds. Very
simple. Give me your email and I'll send pics if
A: I'm building a 9, not a 14,
but I did some research on this topic. Here's what I
1) Of the folks with tailwheels, most did not have
2) The ones that did have them wouldn't have it
3) Of the ones that did not have them there were
some that wished they did.
4) There where some that went through the pain of
installing them post build and thought it was
definitely worth it.

showed less than 1mph difference with and without.

Fuel and Oil Hose Life?
Q: Do you guys service your hoses based on
a 10 year manufacturer recommendation? It came up at
my annual this month. The hoses have no signs of
wear or imminent failure but they are 10 years old.
A: I replaced all my hoses at 6
years. I think Cessna and Piper service manuals say
5 years. I replaced my hoses with teflon-lined
hoses from TS Flightlines. I think those are not
life limited. Plan to leave them until engine
A: I did mine at 10 years. TS
Flight line made me a full set and re-used by
fittings, so the price was not bad.
won't discourage anyone from replacing hoses at
reasonable intervals. But just as a datapoint, both
times I have replaced/rebuilt the fuel and oil hoses
on my RV-6, the stainless braided Aeroquip hose I
took off the plane after several years in service
was indistinguishable from the new hose stock I used
for replacement. Still flexible, if I handed both
old and new hose to someone they would not have been
able to tell which was several years old. But
I still rebuild the hoses inside of ten years for
peace of mind.

RV-14E's VIRB Mount in RV-14 ...and pics
I mounted dual USB power socket adjacent to my
canopy handle. I created a mount for the socket out
of some 1/8" aluminum and some angle. It is attached
with nylon hardware through the tooling hole on the
C-01405-R Aft Canopy Frame.
Questions about RV14A please
I am thinking about building a 14A and wanted some
advice on things please. As I will be exporting the
kit and building it abroad, I wanted to make sure I
get everything I need while I can.
1. What size axle does the RV14A use ? I have some
brand new grove brakes, wheels and tyres left over
from a Kitfox 7 build. The axles are 1.25" and the
brake hardware is Grove 65-211. The tyres are 6's at
the back and a 5 at the front. I have no intention
of fitting the wheel pants on the 14A as the strips
I go into are sometimes very rough. I would like the
larger 6 tyres on the back if possible. Would I be
able to use these brakes and tyres on the RV14A in
place of the stock stuff?
2. I would like to install dual P-mags and use the
automotive plugs in the IO390. Is this something
that Lycoming can do for me or should I order from
e-mag and do the install myself with 2 of the gears.
I presume I can then delete the standard Mags and
harness from the order to Lycoming. Also, do I need
the short or long reach adaptors for the automotive
3. I was planning on going quick build and I
understand that the kit is very easy to understand
and put together. I have just built an RV10, so I
have all the tools and some idea about what I am
doing. How much time will the QB save compared to
the SB version? Is it worth the extra money?
3. Are there any recommended upgrades / aftermarket
parts that I should change on the RV14A. I was going
to get the ready to fit brake lines and FWF hoses
from Aircraft Speciality and the uprated flap motor
with built in position sensor from Pat. What else
should I consider changing from stock?
Thanks in advance for you replies.
RV-8 Status Report ...j-red
11/05/18 Update Cont.
If I never sand a piece of fiberglass in my life, it
will be too soon! We’ve had some warm days
recently, so the opportunity was taken to do some
priming and painting. This required filling the
weave of the cowling with several skin coats of
micro followed by sanding, then thinned epoxy,
followed by sanding, and then epoxy primer and, you
guessed it, more sanding. Really disappointed in the
color coat. I’ll probably need to have a
professional re-do it in the future, but for now it
will have to do.

IFR checkride! Might be old hat for some,
but it's new stuff to me. I passed my IFR checkride

The Vertical stabilizer is a good place to start:
it is designed out of few parts for the sceleton and
one bended piece of an aluminium skin. The
construction of the web is a pretty straight-forward
thing: the rear spar and the front spar are
connected via 3 ribs. A couple of reinforcement
plates to make their reinforcment thing are in some
critical points, and the web is ready for the skin.

Hello RV-12 forum,
I've just started into an RV-12iS project and would
like to introduce myself and let you know what I'm
up to with this build. Of course I'll be seeking
assistance from those here who have gone before me,
and I promise to pay it forward once I'm done -
that's one of the things that make the RV world so
special and these forums so great.
I'm not new to the RV world but have been away for
awhile. I've built an RV-8 and an RV-3B, then took a
break for about 9 years with a stint at CubCrafters.
I've now joined Dynon, moved back to the Seattle
area where I'm originally from, and no longer have
any company aircraft to fly whenever I want. Hmm,
need to fix that.
Further, with my new role at Dynon I need to be
fully up on the avionics world which of course spans
both VFR and IFR ops. While I'm fully up on all of
today's EFIS systems I'm not fully educated on much
of the IFR functionality as I've never taken the
time to get my instrument rating. I've been
intending to get it for literally about 20 years but
have just been busy with RVs, formation flying,
glider rating/flying, and even seaplanes via Cubs.
It's time to fix both issues so I've started into my
instrument rating training and also made the
decision to build an RV-12iS.
My intent with the -12 though is a bit different
from most builds I read about here. I specifically
want an IFR-capable aircraft both for work and
personal use reasons. And, having built two E-AB
aircraft, I'm a bit spoiled by the flexibility the
builder has in configuring the aircraft. Finally, no
doubt I'll be doing some product testing as we at
Dynon continue developing cool new products. I will
therefore build the -12 as an E-AB and will make
some minor mods, though of course nothing whatsoever
structural. As I've done before I plan to document
the build with a web site, and I'll get into my
specific plans there.
So, I'll be spending some time here seeking your
advice and counsel. And please bear with me as I get
my web site up to speed as my immediate priority is
to get my instrument rating done. I am now digging
out all my old tools and getting my workspace set up
and will be starting into the emp kit, which has
already arrived, here shortly.
Feels good to be back!

Well the work continues. I'm ordering all of the
stuff for fireproofing the fire wall, I'm going with
.010" titanium because a sheet of it is still
cheaper than the 0.005" foil from Titanium Goat that
some have used. I also don't like the look of the
0.002" stainless that a lot of people use. I know I
know, no one will ever see it; but that's not true,
I will see it... I guess this also means I have a
somewhat large order to place with Van's for things
like cables and battery box.
Elevator Trailing Edge Dent (Oops) ...Strikefinder
Well, a momentary lack of sense while rearranging
the very tight garage workspace led to my leaning my
right elevator haphazardly against an unstable
structure, which predictably (in hindsight), caused
it to tip over and hit the edge of my wing stand
pretty hard. After many cuss words, I found the dent
below in the trailing edge (which led to more cuss

Question about forward end of fuel line F-12127A in Section 27iS page 7
Is anyone else having
trouble aligning the tube with the bypass fitting
assembly? I realized after cutting and flaring that
I did not bend the tubing forward of the bulkhead in
order to align it squarely with the bypass fitting
Here's a picture that (hopefully) illustrates the
issue. I haven't tried posting a picture prior so
apologies if this doesn't work. I can get the nut to
reach its mating portion of the bypass fitting but
it just doesn't want to thread. I wasn't very
aggressive with the amount of force I applied -
looking for advice on whether this should go
together or if I need to redo this line.

I was expecting a bit more at the top end; I was at

Van's website numbers for 160hp list 186mph at 75%,
I figured the extra 20hp would buy me 10mph?

Setup was an AN3 or AN4 bolt held in a drill press
vice which was clamped to the table so it couldn’t
rotate. I then ran the nut onto the bolt so that
about 1 thread was showing out the end (so full
contact with but threads by the bolt). The scale was
read while the nut was in motion, and the wrench was
held at the end on the black knob.

An Argument for a Carb Temperature Sensor
Carb air temp can be used to check if your carb heat
is working. One of the guys on the field noticed
with his 6A that the carb heat gave him about a 50
degree rise on the ground but in the air he had no
rise in temp unless he pulled hard on the carb heat
knob and held it. He had a ratcheting cable but not
locking. I don't have CAT in my 7 yet but I did hook
up the carb heat with a locking cable which does
give an RPM drop both on the ground and in the air.
There is a chart for probable carb ice condition
which you could use to set your Dynon range. FWIW

November Wallpaper Calendar. Easy choice.
I like the shadow of the plane and the hangar door that
creates a backdrop for the text. The concrete
expansion joints being parallel and perpendicular to the
shadow was icing. Maybe I'm overthinking this.

Damaged dimple on a skin, is it fatal?
Hi Guys ,
I need your educated opinion here, we damaged a
dimpled holes a bit, what do you think is it so
bad that requires a new skin?
here is what happened:
We just started to scuff the VS skin (VS-801PP)
as a preparation for priming / coating.
Accidentaly we applied too much force on the inner
side where dimpled cone is.
As a result there are a few dimpled holes that are a
bit larger now: (about 0.15mm) and they are a bit
flatened , you can see the results on pictures
have to add here that the front side of the holes is
Please advise if it may cause a problem or may
affect the structure strenght.
The big question now is , whether we can continue
with that skin or we have to order a new one.
Looking forward for your recommendations
