Friday I was
lucky enough to pull in to the airport in time to see a 4-ship
coming up initial (video).
The RVs are all 8's and are (I think) Sky, Plaster and Lurch.
We spotted a new church under the downwind leg for 17 recently (pic
/ map). Looks
like they laid out the two benches and cross so that the sunrise is
front and center. Nice touch, and very Texan with the nearby
deer feeder and cows grazing in the same pasture. Hangarmate
John and I unofficially dubbed it 'Aero Valley Downwind Church'.
;^) It compliments the
Officer Big Mac Jail under downwind for 35...(map).

Replacement Ignition Coil Bracket ...Brent -12
Been meaning to post this. I went ahead and
fabricated a very basic replacement ignition coil
bracket from some scrap aluminum angle I had in the
hanger. But, before installing it a friend at the
airport dropped by, who has a machine shop and also
an amazing basement workshop, and insisted that we
fabricate a more durable replacement out of 4140
steel that would be less prone to break again. I
shot this short video for our EAA chapter (we're
going to visit his basement in a few months). He
added a third side to the bracket to strengthen it,
but (not in the video) I needed to remove much of
that in order to be able to get a small wrench in
there to reinstall the bracket on the engine. Those
of you have have had to make this repair know how
tight it is in there.
Over engineered. YES. But was really interesting to
see a skilled machinist in action. After weeks of
maintenance in abnormally cold spring weather,
several SBs, and this last repair, the annual
inspection that wouldn't end is finally done...
P.S. if you check Lockwood's website, the
replacement bracket (# 851260) can be purchased for
something like $11 (surprisingly cheap compared to
most Rotax part prices). So if this one fails, I'm
obviously just going to buy the next one.

Don't Ignore Those Symptoms! ...TomVal
I hope sharing this with all of you may prevent
what almost happened to me.
I have been ignoring my difficulties in passing
urine for about a year. My annual blood test
revealed a highly elevated creatinine level.
I was immediately sent to a hospital for a urinary
tract ultrasound. I received a call by a urologist
the following day (April 24) to report immediately
to his office. I was asked during the call if I was
in pain…I said no…I happen to be working on my
Now at the office, the doctor said, “Do you realize
how sick you are?” I said, “No”. He replied, “If you
wouldn’t have come in today to begin treatment, you
would have been DEAD by May 7th. I said, “Oh my…that
doesn’t sound good!.”
So, I am sitting here with a catheter installed and
on meds. I see the doc on follow-up next Tuesday to
see what menu item he will select.
At age 70+, I have been blessed with good health but
I guess my stubbornness to acknowledge those
symptoms almost done me in…I must now recognize my
ironman days are over.
Please don’t ignore those symptoms.
Now…back to working on the airplane…need to finish
by May 7th (just in case)!

Q: How to build and fly a RV-14 to be QUIET?
Ok guys here's the question, what choice would
you make while building and how would you takeoff to
be as neighbor friendly and quiet as possible
(within reason). Im thinking a vetterman exhaust
with a muffler, maybe a 3 blade mt prop? Any other
ideas and how would you climb out?
Thanks, just brainstorming some ideas
muffler and then 3-blade to get the diameter down.
If you have plenty of runway and feel comfortable
with trading safety with neighbor relations: mark
where you get 2500rpm and do take offs with
if we look for good examples, (not necessarily
practical) you seem to see a trend; more prop
blades, lower tip speed, more cylinders, so each has
less 'bark' ( 6-cyl?), minimum rpm of the engine and
prop, mufflers, and pointing the exhaust up or
sideways at the very least.
airframe noise would be pretty minimal, perhaps not
worth going after those few decibels! I saw the
Lockheed skytamer at Arlington many years ago, it
was almost imperceptible flying over at 100'!!!

SB 14-01-31 ...longranger
I've had the SB 14-01-31 repair kit for a couple
of years now, and thought I'd get it installed
before attaching the horizontal stabilizer to the
fuselage. The number of enlarged holes in the spars,
ribs, and angles (some of which date back to the
original construction) has been bugging me, so I
sent an email to Vans. Sterling concurred, so I am
replacing the front spars, attach and reinforcement
angles, inboard ribs, and new pre-drilled doublers.
I ordered parts Monday, and they are due Saturday.
Yesterday I started drilling out the front spars.
3-1/2 hours into it, I have the left front spar
removed, and am about 2/3 the way through the right.

Check those Rudder/Elevator Counter Weight Bolts!
Make sure you are checking that your counter
weights are secured and the bolts are tight during
your inspections. This one required quite a bit of
work to access, but the loose counter weight screws
were hanging down and almost ready to jam the rudder
The same precaution holds true for the elevator
This is not the first time I've run into this.
PS: the big cut out was required because there is a
bulkhead that had to have holes drilled in it to
access the nuts, these tall rudders have these nuts
buried pretty good.
Hollywood Overfly How To?
Question for California locals. If you are on a

G3X Training at OSH 2018
Hi VAF friends, long time no see!
In December I began working for Garmin in Olathe, KS
on the Aviation Product Support team. I develop and
deliver avionics maintenance and installation
training for avionics technicians. So far it's been
a great career move and I've learned a ton about
avionics systems... even the certified variety!
My team and I will be giving a series of 45-minute
training sessions for G3X installation and flying
each day at Oshkosh this year, and it's time to
start digging in and developing content. So I
figured, who better to ask about what to talk about
than you all??
If you're planning a G3X installation, what would
you like to know? What can we do to demystify the
system for you? If you've already gone through an
installation, what did you have trouble with? What
things could be clearer in the manuals?
I've posted a poll here, but if there's
something else you'd like to know, please reply in
the thread and I'll see what I can do.
Thanks-- & see you there!

A Firewall Detail and a Spar Bulkhead Fitting Issue ...David
There are two areas in the assembly of the

Final Report; 2016 RV-4 fatal accident ...hit zipline.
private pilot and passenger in the experimental,
amateur-built airplane were seen flying at low
altitude by several witnesses in various locations
before the accident. The witnesses reported the
engine was operating before the airplane descended
into trees. Postaccident examination of the
airplane, wreckage path, and a nearby zipline
zipline map dr]
revealed damage consistent with the outboard section
of the right wing having contacted the 1/2-inch
galvanized zipline cable. There were no mechanical
malfunctions or anomalies with the airplane or
The cable ran between wooden platforms on the east
and west sides of a river about 170 ft above ground
level. The location of the platforms in wooded areas
and the fact that the cable was unmarked likely made
the zipline difficult to see. Witness statements and
the accident scenario indicate the pilot operated
the airplane at extremely low altitudes throughout
Toxicological testing of the pilot was positive for
ethanol and tetrahydrocannabinol (THC, the primary
psychoactive substance in marijuana). The blood
level of ethanol was below the regulatory limit;
however, pilots may be impaired below this
threshold. The finding of THC indicated that the
pilot had used marijuana sometime before the
accident; however, since there is no accepted
relationship between blood levels and degree of
impairment, whether the impairing effects of THC
contributed to the accident could not be determined.
Probable Cause and Findings
The National Transportation Safety Board determines
the probable cause(s) of this accident to be:

Piano Hinge Failure ...snopercod
I had one of the "lugs" (I don't
know the proper name), crack off on one of my gear
door hinges. I understand that RVs use lots of these
MS20001-P5 extruded aluminum hinges so I'm posting
this for discussion:
You will notice that the throats
in these old hinges have almost no radius at the
corners - I estimate .005" max, and all edges are
sharp. It's my belief that a fatigue crack started
in the sharp corner where the actuator arm bolts on
(the dirty area in the photo). The replacement hinge
stock which just arrived from ACS has a nice radius
in those corners - I estimate .020" - but the edges
are still sharp. So I just ordered some Craytex
wheels which I intend to use in my Dremel to break
all those sharp edges to eliminate stress risers.
Comments or suggestions?

Flight From KRVH (San Jose, CA) to Healdsburg Plus Santa Rosa Fire Tour
It's been a while since I've flown. Between rain,
cold, vacation, dead battery, and just plain old
regular life, I just couldn't get in the air.
Yesterday I was supposed to take my 1973 VW Thing to
the local VW show but it filled up 5 minutes before
I tried to sign up. I decided to make lemonade out
of lemons and go on a flight.
My primary mission was to fly up and see my good
friend Dave and make him buy me breakfast. I'm happy
to report, it worked!
My route was the typical one I take up there. I go
along the east foothills, east of Hayward (where my
love for flying started as a kid watching the planes

of Oakland, over Berkeley, Petaluma, Santa Rosa, and
finally to my destination. I fly below the SFO Class
B and to the east of the OAK Class C.

mucked it up. Plan B was to climb up to a

Milestone: Wings to fuselage ...Mark Malone RV-7
After 5 moves 9 years and two kids I hit a big

lines up and fits with very little effort. We
installed the wings and the first time there was
only 1/4" forward sweep on both wings. The incidence
had only 2 tenths twist between the root and tip.

Announcement!! JD Air Parts
JD Air parts is alive and well. However, we are
making a transition and I'll be taking over the

Jason Krause, has become highly successful with
several contracts to make parts for ATV's and other
off road vehicles. In other words, he's making real
money and must focus on that. I don't blame him.
With this success Jason simply cannot afford to shut
down the machines from the ATV business making
thousands of parts to JD Air making 50 to 100 parts
in a run.
During this transition we will be there for
questions and warranty and service work on existing
products. We are not going anywhere!!!
I will keep everyone informed when we are up and
running. At this time, I have no exact time frame
but I will be focusing on getting things going as
expeditiously as possible.

First Flight Question
one is for those that have gone before me.
The first flight of my RV14 is not far off, and I
just wanted to get an idea of what I can expect
regarding handling quality.
I notice that a lot of RV14’s have a permanent trim
tab on the Right hand bottom side of the rudder, on
the opposite side to my RV7 which would indicate the
left rudder is generally required. Is this the case
for all RV14’s?? Is there any other handling
qualities that could be expected?
I know there will be variations from build to build
but this one is pretty much a Cookie cutter build as
per the plans with IO-390 and hartzell BA.
Disaster! I’m seriously depressed.
All that was left on my rudder was the riveting
of the trailing edge and rolling the leading edge. I
used Proseal on the wedge instead of tape, so after
it cured I was clearing the holes of excess Proseal
and discovered that almost all of the TE holes were
double drilled (binocular).
Thinking back I know exactly where this happened. I
used a rectangular steel tube to cleco the TE
against. I match drilled holes using the TE as a
guide. It served its purpose well. I had a perfectly
straight TE. I just didn’t use enough care in the
match drilling the tube.
The holes look to be about 15 to 20 percent oblong.
I think I’m going to buy new parts and rebuild the
rudder. I’m not comfortable with such a defect. The
cost is about $320 plus shipping. This is a hard
lesson to learn. It’s not the cost that bothers me
as much as the 40 or so hours I have to spend
rebuilding the rudder.
How did you buck these rivets? ...-14
I'm having a hard time figuring out how to buck
the rivets depicted in the red oval. Looking for
some advice. Please keep in mind that this is a
taildragger so there is a large bracket that goes
right down the middle of the floor.
Have I just stuffed my Pneu Squeezer?
So today I was using the squeezer to squeeze some
rivets for a bracket on the cowl. I was using epoxy/flox
on the bracket and I’m 99.99% certain I didn’t get
epoxy in the stem of the flat set.
In any case, wherever I try I can’t get the set out
of the adjustable piston of the squeezer !!
Does anyone know if I can try to tap it out from
underneath? I’ve tried everything!! It won’t even
twist in place if I hold the piston with a spanner
and try and twist with pliers.
Did I Break It? ...-12
Well, I guess if it ain't broke, I should leave
At the last inspection I noted that one of the
floats was at 4.2. The others were at 3.1, 3.2, and
3.3. Total engine time was 315 hrs.
I had planned to install the new torsion throttle
springs anyway, so I bought a full set of new floats
and installed them at the same time. By the way,
each new float weighted in at 3.2. I fired it up,
warmed it up, and performed the carb balance.
Everything was great and it ran terrific (smooth as
glass). The next morning I was off for a breakfast
fly-in, or so I thought. After warm up I did the
normal ignition check and found Ignition A was
faltering badly. I shut down and did the simple
thing first. I swapped all of the plugs top to
bottom and bottom to top. Sure enough, the problem
moved to ignition B. I don't mess with iffy plugs,
and even though this set only had 115 hours on them,
I installed a new set. All was well, smooth as glass
again and run up was great.
That brings me to this morning when I was planning a
nice morning flight. Having just been through some
issues, I was very attentive at startup, which
seemed good with everything running smooth. After
warm up I did the ignition test and all was good. I
powered up for takeoff and noticed some stuttering,
and promptly aborted the take-off. Additional ground
run testing revealed that it is running very rough
at almost any rpm, and ignition check shows no
difference using A or B. So, I shut down and pulled
it back into the hangar. A finger swipe in tail pipe
revealed extremely heavy soot. I pulled the top
plugs and found #1 and #3 totally black whereas #2
and #4 looked pretty good. Obviously the right carb
is running way too rich. ***THIS WAS AN ERROR***
Actually it was spark plugs #1 And #2 that were
sooty. #3 and #4 were the ones that looked pretty
good. So it ain't the carbs!!! So, my last paragraph
here doesn't hold up, but I left it for
I think that I have identified the fact the the
right carb is running rich. The problem is knowing
why, and what happened? I'm not much of a believer
in coincidence, so I am trying to figure out how I
could have possibly caused this, or where do I go
from here.? Any help will be greatly

on the back surface, but I'm finding no such screw
on the #6 cylinder.
I've already constructed a plenum bypass duct for
the #5 cylinder, which I just completed yesterday

all covered with heat shrink tubing. The correct
sleeve is copper, plain or zinc plated for

For those in Wisconsin
(Thursday) 7pm Founder's Wing at EAA Aviation Museum
milestone today. I finished installing wings,
plumbing, wiring and checked all of my aileron up
and down movements. The stick movement seemed a
little heavy left and right but ok forward and aft.
I probably wouldn’t have ever second guessed the
heaviness had there not been another RV4 in the
hanger next to me. It’s movements were effortless,
but I did have the servos connected from an auto
pilot installed. I thought maybe this added the
extra drag in the controls. Not satisfied I
disconnected the aileron servo and still had the
heavy stick both left and right. I start with left
and right aileron bushings/washers, any possible
rubbing of close parts. Moved on to the aileron push
rods checking all rod end bearings and washers. Next
the bell crank and then the large push rod tubes all
moving freely I install them back and still heavy
left /right movement on stick. I examine the stick
control for binding or interference, and then
finally removed the heim bearings for inspection.
I’m down 2 days so far, but finally found the
culprit. The rear heim bearing has been damaged
ever so slightly. The small crease on the brass
has also creased the interior of the housing race
causing the bearing to bind. I just wished I’d
started looking from that point first. Lesson

Too much slack in tailwheel chains? ...sorta a primer war
There's another post about using or not using

much slack in my tailwheel chains, making it take

Interesting day today, lots of smoke in the cockpit! ...Walt
So while doing a small panel upgrade for a
customer I had a bit a meltdown on his aircraft. The
panel mounted Lightspeed CB, with open and bare
terminals was connected directly to the battery, and
was located right under the xpdr rack I was
replacing (within about 1/8"). Well as soon as the
rack came loose it came into contact the uninsulated
terminals. (of course I was unaware at the time that
this situation existed with a hot bus right below
I can tell you this, there was a ton of smoke
accompanied by some small flames as the wiring began
to burn, disintigrate and melt. All the switches and
master were off so there was no killing this thing
and it just continued to burn until the wiring
finally burnt thru. I was scrambling to get the cowl
off so I could disconnect the battery, but by the
time I got if off the wires has already burnt thru
and opened up.
So whats the moral to this story, do not run 'HOT'
unprotected (no fuse, CB, contactor controlled)
wires into the cockpit. This situation could have
easily presented itself from any number of causes
(loose hardware, wires, breaker, switches getting
loose etc.) If this would have happened in flight
there was no way to kill power to the burning wires,
and trust me with a closed canopy you would be in
serious trouble fast. I was really pretty amazed at
how much smoke there was, in the air this likely
would have ended badly.
For your Hot battery busses (this includes battery
charger pig tails) there should ALWAYS be a fuse (or
some type of circuit protection) located at the
battery to prevent this kind of thing from

RV-8 O-360 Temps and Fuel Flow issues
Just wanted to push out to all of you to see what
you guys think about some of the engine issues I
have. O-360, fixed pitch, dual P-Mags, Dynon D10
EMS. CYL #3 runs VERY hot even on cold days, even in
cruise with CYL 2, 4 not too far behind. CYL 1 runs
much cooler than the others. You can see some temps
I see on climb and cruise taken on a winter day at
altitude. Anything slower than a 100 KT climb will
have my #3 CHT shoot to above 430 rapidly.
Also on climb out and WOT I will see my fuel
pressure typically drop quickly from a nominal 3-4
PSI to .5 and 0 PSI which sets off the alarm. I've
noticed this is often accompanied by an increase in
fuel flow. Turning on the electric pump will push
these up to 4. Securing the electric pump, the PSI
will gradually decrease again to .5-0. Once
throttling back to cruise settings the fuel pressure
will climb back to nominal.
I am wondering if any of you have any ideas on the
fuel flow and the over heating. What's a good way to
check the baffles? Are there any good plenums out
there for my configuration that has shown good
success in cooling so I can do away with worrying
about baffles? Searching through the threads it
seems adding a washer helps with cooling but I'm not
quite sure where that washer is being added....any
photos to show this?
Otherwise the motor runs nicely and no noticeable
performance issues associated with the drop in fuel
Any input is greatly appreciated!

Here is one way, but the baffle would have to be

head polished at the same time. Why have the fins
and allow them to be blocked off? This provides a .2
X 2" slot for air flow, at 5-15 in-h2o pressure that
is a lot of air directly applied to cooling.

Tuft Testing RV-8 Sub-Cowl ...JP White video
My partner and I felt we were
overcooling our O-360 XP so he designed and built a
sub-cowl to reduce the exit opening and reduce
cooling drag. We expect the reduction in exit
opening will increase the CHT and oil temp. Testing
has been limited due to weather and schedule but we
have noticed a very modest increase in CHT and oil
temp. I tufted the belly around the exit and
recorded the flight to get an idea of how the
sub-cowl disturbed the airflow. The test was at
3000' and 160 - 170 mph. A link to a short video is
attached. RV-8 with custom plenum and Sam
James Cowl. Carbureted 360XP with Mags. FP Cato 3
"The ramp surface of your sub cowl is separated
because the angle is too steep, so there is too much
adverse pressure gradient.
I trust that the leading edge of your sub cowl
blends smoothly into the round lip at the front of
the stock cooling channel? If not, then the flow is
separating off of a sharp corner. If yes, then it is
an adverse gradient problem as stated above.
This is just one of the reasons why it is far better
to throttle the exit by making the actual cowl fair
into to a smaller opening rather than add a bulge to
the belly. The other reason of course is that the
frontal area is reduced at the same time."

Snowbird Classic IAC contest PIREP
The 2018 contest season has gotten
off to a good start!
We started off in March with a successful judge's
school. I got recurrent and now it was time to start
judging. I was hoping to start by judging either
Primary or Intermediate. The problem was Primary was
combined with Sportsman for this contest as it often
is. So I wasn't permitted or able to judge the
category since I am a Sportsman competitor. The
Intermediate category was being flown just prior to
my category so I wasn't able to judge it. So for my
first judging experience as a qualified Regional
Judge I got to judge the Advanced category! I was
bit apprehensive about this since the competitors at
this level are very serious and I didn't want to
screw it up for anyone. Plus, the maneuvers happen
very very fast, making it easy to miss important
elements. You know what... the training worked! I
was able to successfully judge in a fair objective
manner consistent with the more experienced judges.
I was as pleased with this as I was with my flying.

14A flying feedback after 237 hours ...bmarvel
I rarely post but thought some of you in the early
RV-14 flying stages or nearing completion may be
interested in some real-world feedback. I first flew
our -14A on September 8, 2016 and now have 237 hours
on it. Prior to that I put our RV-8A through some
1700 hours so I know the pros and cons of each. Our
-14A was a standard full build kit (SN 140134) with
an IO-390 from Van's and the recommended Hartzell CS
prop. It is IFR with two Skyview displays, GTN-650
navigator and a back up Grand Rapids Mini-B EFIS. It
has an impulse coupled mag on one side and P-Mag on
the other. I followed the plans closely and only
made minor modifications to them.
In no particular order, here are some thoughts,
characteristics, performance data and features that
may be of interest to you:
1. Both the wife and I find the -14 to be more
difficult to get into and out of compared to the -8.
One hand on the side rail and the other in the
center of the cross bar behind the seats is required
to support your body weight, especially getting out.
It takes some stretching to do. Don’t let pax grab
the instrument panel or canopy, as they are inclined
to do. Holding onto the roll bar while facing
inboard and standing on the seat, then turning
forward while crouched down like a baseball catcher
leaning against the seat back is a technique that
works. You may end up developing your own method
that differs but that’s what I do.

Stu 'Falcon' McCurdy's Gathering...this Friday
I wanted to provide you with an update for Falcon's
local "open hangar" gathering
Friday April 6, 2018 from 1300 to 1500 at the
Georgetown, Texas airport.
We are hopeful the weather will hold up and that we
can accomplish all that we can on such short notice.
We will plan on starting the posting of the colors
at 13:45 followed by an eulogy and stories about
Falcon. We will perform a missing man in his honor.
Any one that has served or flown with him don't
forget to bring your nickel. Please think of a short
story or quote you would like to share with those in
attendance. Remember that this is as much for his
family as it is for him. I believe it is important
for his grandkids to get to hear these stories they
otherwise would not hear. Please think of a brief
story if you want to share one. Try to keep them PG
as most of us coming from fighter squadrons tend to
have some flowery language at times, along with some
of our sayings. That said Falcon loved the
camaraderie and shenanigans as much as he loved
formation flying. He would want it that way.
Please let me know if you need anything further. I
hope to see you at the "Falcon Gathering".
Please forward this to anyone you may know that
would like to know about this gathering as I am sure
I have missed someone, unintentionally.

RV-8 Heat Diverter- Solution to a Nonexistent Problem?...goatflieg
When I installed Van's cabin heat selector box on
my RV-8 firewall I saw two potential problems. The
first was routing the push-pull cable; with ground
adjustable rudder pedals set full-forward I saw the
potential for getting the top of a pedal caught
behind the cable during brake actuation with rudder
deflection; definitely NOT a good scenario. I
decided to modify the flapper lever and route the
cable directly from the left gear tower to the
lever. This would reverse the operation to
push-to-open/pull-to-close, but that's no big deal
to me. The other issue was that it looked like the
hot air would be blowing directly into the left
corner in front of the gear tower; less than ideal,
with wiring, cables, fuel pump, fuel lines and brake
lines there. I thought a heat diverter would help
reduce those issues and redirect the hot air
straight aft. So I made this up out of scrap
aluminum. It was eyeball-engineered and took some
fiddling, but I believe it will help. Having to
route the cable through the diverter was a pain, but
it works without any interference. Just wondering if
any other RV-8 builders had similar thoughts. Did I
solve a nonexistent problem?

in the GA world, especially the EAB side, would not

standard to which we are all held. It allows dozens
of flight teams, consisting of hundreds of pilots,
to fly together in safety and grace. It seamlessly
brought together pilots from all over the country to
set world records, whether over EAA AirVenture, NFL
games or the occasional NASCAR race.

Fishing Guide RV Offer (NE. OK) ...friend of mine Clayton (RV-8)
Adam Mason is a friend of mine here in North East
Oklahoma. He was born and raised in Adair and has
been fishing Hudson Lake since he was a kid. He has
started up a fishing guide service, and I was hoping
to get the word out to the RV community since this
would be a great use of an RV. Adam is a Veteran,
having served in the Army between 2004 and 2012 -
with a tour in Iraq (2006/2007) as a .50 Cal.
Infantry Gunner. Not exactly sure what he was up to,
but I'm damn glad he was doing it.
Here is what Melissa and I would like to do to help
out. We would like to offer accommodations for two
different 2 person parties who wish to book fishing
trips with Adam. They can come into our grass strip
(OK18) on the lake the night before and either stay
in the one bedroom apartment we have at the hangar,
or if they prefer, they are welcome to pitch a tent
and camp. OK18 is a private strip with a "Land at
your own Risk" policy, but if they have some time
operating off of turf, coming in and out of OK18
should be no problem.
Pics and Contact Info
I would encourage interested parties to first
contact Adam about time and schedule. I know he has
been having some great results on Crappie and that
the Sand bass are really turning it on right now.
Melissa and I spent all day Saturday putting them in
the boat. Early in the season the Spoonbills are
really stacking up and the Catfish will be biting
here soon. Adam offers a full services guided trip,
all equipment, bait, lures, boat, and fish cleaned
for you to take back home. The fishermen/women will
be responsible for the appropriate fishing license
and their meals. His 1/2 day trips are $300 for
either 1 or 2 guests in the boat. I can guarantee
you that anyone who goes with him will have a good
time and Adam will do all he can to put fish in the
boat (remember - he can operate a .50 caliber rapid
Once the party has booked with Adam, I will be happy
to brief them on OK18, alternates, fuel,

Although I would not call myself a hoarder when
it comes to little bits of aluminum I am definitely
In 1993, when I started, you kept all the scraps. If
you wanted to build something extra, or had a
repair, little pieces came in handy. When building
if you were going to modify a part you needed little
pieces. The really expensive piece of small aluminum
is the one you do not have! I kept everything,
different sizes, different thicknesses etc.
As kits have evolved there is less and less need for
extra metal. The kits are pretty complete and there
are not as many modifications to make. The baffle
kit alone has saved hours and hours of work
scrounging for just that right bit of metal.
After completing the RV14 I noticed that I did not

From Sonex to RV-8
Years ago when I first decided building an airplane
was something I wanted to do, I was quickly drawn to
the RV-8. As I started researching what it would
take to build one, I started realizing that cost to
build and the complexity was probably more than I
could chew. I found myself migrating over to the
Sonex, and after a Sonex builder took me for a quick
hop around the patch, I was sold. It had great
performance for the price and I was able to see past
the somewhat odd look and overall lack of fit and
Fast forward a few years and I am part way through a
Sonex tail kit but have started to have a lot of
apprehension about finishing. This is mostly due to
my lack (and others in the Sonex community) of
confidence in the AeroVee VW conversion. With the
Sonex B models, the factory will now support several
other more proven engine installations (Rotax, UL
power, etc.) but that takes an airplane I was
looking to spend 30-35k to get airborne to more like
50-60k. While I still feel the Sonex is a great
little airframe, I can't see paying that kind of
price for it.
So, I've come full circle back to the RV-8, which
has always been the plane I wanted to build in the
first place. I am going to order a set of preview
plans and the practice projects and figure out what
extra tools I'll need now that I can't just pull a
bunch of pop rivets. Any other building
advice/suggestions for a soon to be former Sonex
builder would be appreciated.
Looking forward to the journey!

I put three access panels in the front skin of my
9 tip up. It’s time consuming to do it. I asked a
friend that put them in his 7 if he would do it
again and he said yes. So I went for it. They made
it very easy for riveting the skin. I’m assuming you
have not installed the skin. Important. When laying
out the holes, the two that are on the sides run
parallel to the longeron. They are trapezoids not
Layout the locations on the skin and carefully
cut them out, file and clean the edges. Layout and
drill #40 holes around the perimeter using proper
edge distance. I used a rivet fan to space the
holes. Cleco on the skin to the airframe to fit the
backer plate. Rough cut the plate oversize as it
will change as it curves. Match drill the backer
plate and cleco all around. Trace with a sharpie
around the hole onto the backer plate. Remove the
backer plate and create an outside line 5/8” from
traced line, then do the same 5/8” inside the traced
line. Cut both inside and outside line, clean and
polish edges. You now have your backer plate.
Next make the cover plates. These must be made
with the skin cleco’d to the fuse. Rough cut larger
than needed. Match drill and cleco. You will need a
helper to climb in and push the plate to conform
while you match drill. Trace and cut 1/8” outside
the line. The plate now needs to be finely tuned to
fit the hole. Cut and file to fit. Cleco on the
backer plate for support while fitting. When your
happy with the fit, if not make another one, layout
#40 holes, match drill cover plate into backer
The rest is straight forward. Dimples for rivets and
#6 screws in cover plate. Install nut plates in
backer plate. Last is to rivet the backer plate if
your satisfied with the fit and finish. Otherwise do
it all again. It’s only a small amount of 032 sheet

My Vans RV Conundrum ...new guy Dave chimes in
I have been thinking seriously about trading my
Mooney for a Vans RV-9/A. It better fits my mission
which is mostly me flying around by myself in good
weather with no particular place I need to go. I
think it would save me a bit of money in fuel burn,
replacement parts and upgrades and it would be newer
with not so much history, mechanics, repairs,
annuals and the like on it.
My ideal Vans would be the 9/A with an IO-320, CS
prop and either a tip up, or slider, I haven't
decided. It would also have to have a nice, standard
layout panel with at least two axis auto pilot, dual
coms, WAAS GPS, engine monitoring and a good audio
panel. ADS-B in and out and a 406 ELT would be great
too. Unfortunately there are four serious things
preventing me from pursuing this plan. In order of
What do you guys think?
Safety. I like the 9 because it has the lowest
stall speed and that means the slowest touch
down in an off field landing scenario, but it
seems that if you land a Vans on anything that
isn't hard and prepared, you end up upside down,
hanging from your harness and most times trapped
by a stuck canopy. Ditching a Vans in water
sounds like suicide, or at least very, very slim
chances of a good outcome. I feel much more
confident in the Mooney's ability to land off
field and in water. I also feel very confident
of the Mooney's strength in the airframe. I'm
not so sure about the Vans.
The wife. I mentioned in passing that I was
thinking of trading the Mooney and she was
ho-hum about that... until I told her I was
thinking of an experimental! She was pretty
strongly against that idea! It will take a lot
of convincing that it is just as safe and I
first have to convince myself.
The wife. The cabin in the Mooney is tight, but
I think the Vans cabin is even tighter. It feels
very narrow to me. As we get older, neither of
us is getting any skinnier. There is also poor
baggage area access, or capacity. While it has
only occurred three or four times in the last
seven years, it would be nice to keep the
ability to take the wife along for a weekend.
I'm not so sure how well the Vans can handle
Money. I don't think I can get anywhere near
enough money for my Mooney to get a nice clean,
well built RV-9 configured the way I want it and
then do all the things that will need to be done
to make it mine. I will have to sell my Mooney
and then likely pony up even more money. While I
have the money and could do this, right now is
not a financially great time for me to do it.

Head hitting canopy fix
The sometime sharp-edged turbulence around the
local foothills has caused my head to hit the
(RV-14A) canopy fairly hard several times, even with
the 5-point harness snugged up tight. The problem
seems to be the location of the lap belt anchors
well behind the seat. While doing a good job of
restraining in the forward direction, vertical
motion can easily be 4-5 inches. The solution seemed
to be an extra lap belt anchored further forward.
I got some seat belt anchors from Van's and located
them about 9 inches forward of the stock ones (see
first pic). The mounting would have been simple
during the build, but out on the tie-down, not so
much. The floor beam material is quite thin, so
added an .060 angle and stiffener on the side
opposite the anchors using plenty of pro-seal and
two AN-3 bolts (see pics 2 & 3). Pic 4 shows the
installation with the ratcheting lap belt (wrong
color, but hey...). This has been very effective,
you can ratchet the belt down till your bones bend
and you definitely become one with the airplane. My
head hasn't hit the canopy since and I also really
like the feeling of being glued in place even with
the simple acro I do.

Short Field Practice ...vid.
...and (11) more minutes to get the logbook entry
Tuesday a.m. was one of those cold,
windy mornings in N. Texas that allows for a very
short landing roll on 35 at my home field.
Since I have manual flaps I like to occasionally
(when the conditions are right) dump the flaps right
as the wheels touch to shorten the roll. The
landing roll measured on GoogleMaps later was 698'.
It'll do shorter with less gas and smoother air.
My 'fun rolls' are a cross between barrel and
axial. Maybe 1/3rd barrel - just enough to
keep all the junk on the floor. The G-meter
showed 2.5 in the loop.
The wind was gusting 21kts
about 20* left of the centerline. The burbles
off the hangars make the 35 landing 'dynamic', and
the slightly-rising runway there at the end calls
for a non-standard flare. You can see the
bumps down low. Game face on and always
something to screw up (which I usually do).
hooked up the Garmin VIRB that's on loan and played
with the edit software a bit. Maybe an excuse
to goof off at work for 2min 40sec if you have the
bandwidth and monitor acreage.
Hard to believe how
much fun you can have in 12 minutes with an RV.

Difficult situation - need help ...jonweisw
A dear friend of mine needs to sell his RV
relatively quickly due to a tragic loss of his
medical related to a very significant,
incapacitating, health issue.
He completed his 7A in 2005 and it has around 600h
on it. IO360-M1B with a Hartzell. Beautifully built
(seriously - he is a former Navy test pilot and the
attention to detail was nuclear-grade) and
impeccably maintained. Always hangared and NDH.
Unsure as to the extent of his recovery and whether
or not he would be airworthy again, he and his wife
have held onto the airplane but have now decided to
sell it. It is out of annual and based at Punta
Gorda, FL (KPGD).
I have advised her that getting the airplane an
annual and therefore airworthy should be a top
priority (it is not safe or feasible for him to do
the condition inspection subsequent to his event).
Do any of you know of an A&P in the Ft. Myers area
who would be willing to do an annual on an RV? The
airplane will be on the market soon, so this may be
a good all-around project for a potential buyer as

Cold (not dead) cylinder at high MP except WOT ...Rick 9A
I’m observing some behavior that I
would like the group’s opinion on.
Setup: O-320-H2AD, 33H Hobbs/19.5H Tach since OH
with new cam, lifters, new Lyc cylinders. Ellison,
standard dual mag (D3000) also OH. Sensenich fixed,
RV-9A. Compressions are 76/80 or better cold.
At full throttle/WOT – 28.5in HG for the most recent
flight - at low altitudes (takeoff), CHT and EGT’s
line up well. EGT’s are in the 1250F average range
for what it’s worth, all rich of peak. At MP’s
slightly below WOT to medium throttle – 27in HG to
20 in HG– cylinder #4 EGT falls by 100F-150F and CHT
for #4 falls by about 30F-40F versus the average of
the other three. The EGT falls fast and settles out
with thirty seconds, CHT takes a couple minutes.
Below 20in HG, all four cylinders come back together
again in EGT and CHT quickly. It is repeatable,
centering around 20in HG MP.
There really isn’t any perceived roughness, and even
in this 27in - 20in HG cold-cylinder range, #4 EGT
and CHT responds normally and consistently with the
other cylinders to leaning, they are just doing so
from a significantly different place. Since I lean
to basically 100F-150F ROP at anything less than WOT,
I can’t say if ranging from full rich to lean
changes the behavior at the transition points. I
believe it’s been occurring since hour 1.5 based on
the data (no high power data exists prior to this
time, <1.5H is all run-in), and there is no
significant metal in the first two oil changes,
suggesting I’m not wiping a lobe.
My first suspect is ignition, looking for one side
of the ignition falling off on #4. I have not done
any disassembly inspection yet, only gross
inspection of the ignition harness - no obvious
ignition leakage or damage to plug wires, and timing
is on target. I did check the intake tube clamps
(thanks Ralph, I should have mentioned it).
My plan: Run the Savvy ignition test in flight, in
various levels of richness/leanness and MP’s. If
it’s ignition, I expect it will show up pretty
clearly, and the diagnostic work from there is
(hopefully) logical: plugs, harness and magneto get
the focus. I’ll probably look at the plugs anyway –
a cylinder running that cold may be generating
deposits that may point at something (one plug not
firing being scuzzy?).
If that doesn’t give any hints, I will confirm my
secondary elements: valve lift, boroscope, pushrods.
Any hints or past experience would be welcome.
Paint Booth PIREP ...Shawn Jordan
I’m in the middle of painting my RV-4 in my
homemade paint booth and boy was I suprised. I have
A 7000cfm fan pumping air through 16sq/ft of inlet
filter and I can still fully fog up the booth with
the SPI high solid clear. I cant imagine trying to
close loop this air. If you look in the second
picture you can see how dirty the inlet filters
already are after just shooting base coat on the
fiberglass pieces. Love the scientific approach to
this though, don’t see this level of approach on the
good old car forums.

did the inspection and it was a pleasant experience.
This guy knows his stuff ! At the beginning of the
build I asked a good friend John Hubble what he
would do different if he was doing another 10 (he
has a beautiful RV-10). I did everything on his
list. It was extra hours, but I'm very pleased. I
did the Rod Bower inlet, all Garmin G3X, touch and
many other after market items. I bought so many
goodies from Aerosport Products, that they sent me a

New Builder and Trailing Edge Question
I'm a new RV-14 builder - yes, no 'A' and little
wheel in back . I am working on the rudder and have
a question for the community. Sorry if this was
answered, but I couldn't find any information from
On page 07-09 - steps 1 and 2, the instructions say
to use adhesive to bond the trailing edge. However,
on page 07-10 - step 2, the instructions say "The
trailing edge will have to peeled slightly ...". I
was planning to use the 3M F9460PC VHB tape as
specified in section 5. Looks like the 3M tape is a
permanent bond, so why would we bond the trailing
edge, then attempt to peel it apart again? Won't
peeling the edge apart potentially damage the skins?
Has anyone used the 3M tape for the trailing edge?
Looks like Van's used to recommend using fuel tank

A variation on the Dynon Network Hub ...az_gila
For my -6A I used a single Skyview

make hook-up easy, but splitting power and putting
splices in the servo cables bugged me.
So, for my -10 build I came up with a simple
alternative idea to Dynon's network hub. I designed
a 5 port hub, but added two custom connectors
dedicated to servo hook-ups only, all on a single

cleaner solution to the servo power wiring issue. I
can now connect all of my planned network items

the cruise at 23/23. IO-360, 350 hours from new, no other issues.
Pulled through 4 great compressions after the flight with no
EGT probes are old on 1, 2 and 4 - planning on changing soon.
Ran comprehensive ignition check in the cruise, no difference so

Aresti Made Simple
For those that may have an interest in aerobatic competition, I
realize that one of the things that may seem complicated is the
Aresti System. The Aresti System is a system of depicting and
scoring the many aerobatic figures and their multitude of
variations. It’s called a system because there is method to the
madness. It was designed by a Spanish Air Force Colonel, José Luis
Aresti, many decades ago and it is used universally for aerobatic
competitions. The files below are written for the r/c
(radio-controlled aircraft) community and it is presented in a
simplified method. Caution, there may be some differences from the
actual Aresti catalog.

RV-8 and the Clear Day
Saturday, 3/10/18, was a rare clear day in both
Western and Eastern Washington allowing for easy
travel over the big pile of rocks separating the

down low in the vicinity of Richland. The route took
us from Arlington to Richland, to Moses Lake, to
Stehekin, and back to Arlington. About 365 NM in 2.7
hrs (my flyin' buddy made it in a little less [his
-8 is faster]).

RV-10 Doors and Tinnermans
How do you determine..and fuel levels
How do you determine if you have
resistive float senders, or capacitive senders in
I am beginning to calibrate the fuel levels in my
RV9A for a GRT EIS system, which I didnt build, with
a bit of difficulty.
On my attempt yesterday, I filled the right tank one
gallon at a time, noting the reading on the EIS
after each. The empty reading was 4.2 It began to
change on the 4th gallon.
Then, it stopped changing at the 7th gallon, and
read 5.7 each gallon there after. this isnt going to
Resistive usually are just a flat thin metal plate
on the outside of the tank and capacitive are
usually 1/2" thick and plastic with epoxy filled
center. The gauges normally do not read right to the
top and if the sensor was not installed all the way
to the bottom it might not read down to one gallon.
A: Restive senders have
only one wire, airframe is used as ground to
complete the circuit.
Capacitive units that I have seen will have two
wires, sometimes coax, and use a converter box.
A: OK, As far as I
know, I have but one wire.
But..I didnt trace it to the tank.
The craft had the standard Vans 2 1/4 round fuel
gauges in it. they seemed to work ok in the 75 hours
I flew it before I started the GRT upgrade..
IF I understand this GRT EIS fuel level calibration
correctly, They recommend using the reading for full
tanks as the level where the float sender stops
changing..and the empty reading as the level it
stops when going empty..in my case, it seems that I
will have an empty reading at 3 gallons, and a full
reading at 7. hmm..as I said, thats not going to
work for a 16 gallon tank.
I went thru the math several times on the GRT
Im scratching my head. If the sender output stopped
increasing after the 7th gallon added...I guess it
could be faulty..hard to believe it would only have
a 3 to 7 gallon range of motion. (if its a float)
aircraft was level sitting in the hanger.
A: First, check the
wiring. You should have a wire from the regulated
power (4.7 volts, I think) going to a resistor (470
ohms). The other side of the resistor is connected
to both the EIS input for fuel level, and the center
terminal on the float gauge. The other side of the
gauge should be grounded locally.
Turn off the aircraft master switch (power off).
Disconnect the wire from the float gauge center
terminal. Put an ohmmeter on the center terminal,
and measure resistance to ground. It should be
somewhere between 30 and 250 ohms.
If all this works, there are several ways to trouble
shoot. My guess is on the wiring.
With the wire still disconnected, but not shorted to
ground, turn the power on. Put the voltmeter on the
disconnected wire and measure the voltage (other
probe on a good ground). It should be 4.7 volts. If
not, there's a wiring problem. With the same setup,
carefully hold a 470 ohm resistor between the probes
(while still in contact with the wire). You should
see the voltage drop in half, to, 2.3 volts or so.
If grossly off, you don't have a 470 ohm resistor on
the other end. You'll need to find it and replace
Finally, if you suspect the sender:
Drain the fuel, then start adding it back into the
tank. Measure the resistance each time you add fuel.
You should see it smoothly go from about 250 ohms to
about 30 ohms (probably stop changing as you get
with 3 or 4 gallons of full). (I might have it
backwards, 30 to 250? I forget.)

SB 18-02-02 PIREP ... scottmillhouse RV-12
Just finished this up today and it probably took
closer to 16 hours than 6. I prepped, primed and
painted all parts before disassembly of the tail. No
real pitfalls until reassembly.
Then spent hours getting the pivot bolts and spacing
washers in. The newly boxed in structure makes
access much more challenging and only from
underneath. Connecting the stabilator cable
tensioner solo is extremely challenging but I
eventually worked out a way to do it solo. Connect
the top, pull the lower cable as far forward as
possible, wrap tape around the clevis body and clamp
lightly with vice grips from the bottom. Insert a
piece of cardboard at rear bulkhead to protect it
from the vice grips. (the vice grips will push
against the bulkhead and lock the lower cable
position) With your right hand use the tail leverage
to match holes by pulling down on the rear of the
stabilator. When aligned insert a short #3 bolt in
from the trim motor side. Then slowly from the right
work in the correct bolt to the right clevis side to
put in the spacer washer and then to the left to
install washer followed by outside washer and castle
nut/counter pin. Probably is impossible solo to pull
the cable tension directly from the clevis and put
in the bolt.
Also plan on a lot of trimming to the top rear
fuselage cap faring if built per plans. The exposed
plates are notched but the notch ends probably 3/8"
farther to the front than the clearance previously
required for the box spar. Bottom is easy, just the

Big Bend - Lajitas Golf Resort & Spa ...tcard RV-9A Trip Write-up
I have a friend, 'crazy Marti'
according to Scott, that is an amateur photographer
and bluebonnet fanatic. We've been talking for a few
years about trying to fly down to the Big Bend area
in Texas that has a different variety of bluebonnet
than what we have in Central Texas.
Ours grow low to the ground in
dense fields, but in the desert they are sparse with
flower stalks that get several feet tall. The stars
finally aligned in 2018 for a 3-day girl's get-away
weekend. The lodge in the park was already fully
booked, and as it turns our that was good luck for
our bluebonnet hunting crew. The option of flying
into Alpine or Marfa and renting a car didn't sound
very entertaining. The winning selection was to stay
at the Lajitas Golf Resort and Spa and land at its
6000' x 100' private airport. Luck was shining down
upon us, and I think we got the cheapest room in the
joint at $210 a night.

First oil change - ran into an issue...JackinMichigan
Attempted to do the first oil change on my Lycoming
IO-540 today after 5 hours of engine time (break-in
oil) and ran into a problem. When I got the old oil
filter off, the one that came with the engine (and
it was a BEAR to get off), the threaded brass nipple
that I'm pretty sure is supposed to stay in the
engine came off with the old filter. It's solidly
affixed to the old filter, and there's nothing to
grab onto to try to spin it off. I'm leery of
cutting apart the filter for fear of damaging the
threads (oil and fuel systems are things I try not
to get too creative with), so before I continue I
want to throw this out to the group:
- How do I get this brass nipple out of the old
filter? If that's not advisable, where can I get
- Would off-the-shelf Locktite prevent this from
happening again or is there something better?
Thanks in advance. You guys never disappoint.

RV TRANSITION TRAINING SURVEY ...Dick VanGrunsven
(from the mothership FB page)
It is becoming increasingly evident that the fatal
accident rate for RVs is considerably lower than
that of E-AB aircraft in general. While it is
difficult to calculate exact rates, most accident
analyses show it to be approximately 2-4 times less
than the average. I think that insurance
underwriters would agree in that they more readily
provide coverage for RVs than for many other E-AB
designs. These same insurance providers indirectly
contribute to this elevated safety by requiring a
prescribed level of specific aircraft type flight
experience prior to providing coverage. This is
usually in the form of Type Transition training.
Fortunately, there are a number of highly qualified
TT instructors who offer quality training in various
RV models. This training undoubtedly contributes
directly to lower accidents rates.
Many years ago this was not the case. Builders of
E-AB airplanes either simply became overnight “test
pilots”, or at best could garner a familiarization
flight with some willing RV pilot. “Take the
controls for a while to get the feel of it” and
maybe “shoot a landing or two” if conditions
permitted was a common indoctrination into the realm
of flight test. The thousands of you who have had
the good fortune and sense to receive quality TT
training can most assuredly see the shortcomings of
this methodology. Throughout homebuilt history,
accident rates for “first flights” and operations
during the “first 10 hours” have been appallingly
high. Sadly, for many models of E-AB aircraft, this
reality continues. It is demonstrably better for
RVs. This is due to a variety of reasons, but
superior pilot preparation/training is arguably a
I am inclined to believe that in
addition to the obvious benefit of exposing the
trainee to the unique qualities of a specific
aircraft, the requirement that trainees meet a
stringent “stick & rudder” standard set by exacting
TT instructors yields an elevated level of
competence and refinement. This may be a slight
overstatement; however it is my belief that our TT
instructors impose a higher criterion for pilot
performance than is expected by examiners of newly
minted private pilots, or by instructors providing
biannual flight reviews. If my observation is
correct, we may have re-discovered a safety secret;
better pilots. Not just better prepared to fly their
new RV, but better regardless of the aircraft they
choose to fly.
On this basis, wouldn’t most GA
pilots develop into becoming safer if they were to
receive similar “upgrade/refresher/recurrent”
training? You undertook this type-training because
of insurance requirements, your fellow RV builders
encouraged it, and you possess good sense. Enticing
other GA pilots to take “self-improvement” training
perhaps may be difficult without the specific goals
and motivation you had.
My purpose in writing this is to solicit your input.
If you had TT prior to test flying your RV, I’d like
to hear your comments on the training specifics you
considered most important and reaped the greatest
benefit. To name yourself or instructor is not a
requirement. Obviously, to validate my observations
and opinions as stated above would be gratifying in
light of our overall goal of increasing safety but I
also welcome differing experiences and conclusions,
regardless if being contradictory to mine. We learn
from sharing. If you have suggestions for ways of
encouraging all GA pilots to take upgrade training,
please include them.
I’d appreciate your prompt
response so that I may use this as a basis in
advocating for more widespread TT within the
homebuilt community and beyond. If better pilot
training improves RV safety, we need to spread the
good news to all in GA.

Lycoming Carbureted O-290-D2 EGT out of Family ...snopercod
The saga continues
I watched the carb temperature all winter and never
once saw the temperature get down into the icing
zone, even during an idle power descent on a cold
day. Enough heat is transferred from the oil sump to
keep the carb warm. So I'm confident that my
particular engine just doesn't need carb heat on
descent. (Of course it's there if I ever need it.)
I'm still debating the wisdom of removing the temp
sensor that sticks out into the throat of the carb.
Several commenters have recommended that and they're
probably right. What I have found over the last six
months is that the rearmost cylinders 3 & 4 run lean
at WOT on takeoff with the mixture full rich. That's
probably not a good thing, but to compensate, I pull
back on the throttle a little when reaching 500' and
the EGTs even out. You can see that in the graph
below. It's curious because I would have expected
that with the throttle fly vertical, more fuel would
reach the rear cylinders than when the fly was aimed
more toward the front. I think my next step will be
to drill out the "peppermill" holes I drilled in the
nozzle years ago to provide more fuel to the rear
cylinders. IIRC, they're only #57 now, and in the
photos of the Marvel nozzles, they look much bigger.

#2AWG welding cable and new heavy terminals voltage drop during
cranking was 0.4 volts from 12.5 to 12.1V . Voltage drop on ground
side was only 0.15V.
Despite what armature shop says, I think I have an internal starter
issue. I guess next step is a new starter. My starter is a
Delco-Remy Prestolite. I don’t really want SkyTech or B&C
lightweight starter because I need the weight up front the old
starter provides. I already have the Landoll balancer ring.
Low fuel Pressure Root Cause maybe
I have a fuel inject Superior 320. Over the last
few months I have been experiencing intermittent low
fuel pressure until now where it is consistently low
(5 - 10lb) The backup pump must be run for the
engine to stay running. Knowing that the engine
driven fuel pumps are very reliable I started
looking else where. What I found is what appears to
be a failure with the fuel plunger and the cam(see
So I have two questions; any ideas how this could
happen, could this be a defect in the plunger or
Second - To fix this will obviously require pulling
the engine and accessory case. What I was thinking
was just adding a second electric fuel pump forgoing
the mechanical pump. I have dual electronic ign, so
I'm already electrically dependent. My bigger
concern is hot starts. The mechanical pump vs. the
full pressure of the electrical pump on startup.
any help would be greatly appreciated!
Haven't quite figured out the quirks of nutplates
yet i guess.
This is the tie-down AEX attached to the wing spar. The bolts here
attach a powder coated bracket which I think is part of the aileron
actuation bits and pieces.
Did I strip it? If so, do I need to drill out all the rivets to
replace this nutplate? Or just change the bolt? I think this
happened because my socket was too deep to help push those first few
threads in. I have been using a dab of wax on the bolt.

Build PIREP ...jcarne 7A
The airplane factory is back in action!!! After waiting a painful
couple of months for the weather to get warm it is time to get back
into the garage for perhaps my most productive year yet!
Back in January my fueselage kit arrived, btw, when FedEx shows up
later than expected and you think you can move the fuselage kit with
just your wife, start making calls to avoid an argument!
I underestimated what a pain that box was going to be to get into
the house but we got it done.
Like Christmas two weeks later!

RV-3B Construction PIREP ...David Paule
I finally reread the manual for the areas I've
been working on. Should have done that earlier, as
it would have told me the correct way to assemble
that spar bulkhead strip that I had to unrivet. The
manual says "The rivet holes through the skins and
the bottom flanges of bulkhead F-303 should not be
drilled until both skins are in place."
I agree with this with one exception: if you drill
through the bulkhead flanges first, then when the
skins are in place, you can back-drill through the
skins using a 12" bit, and there will be no
difficulty locating the holes on the skins. Just
watch out for edge distance when you're locating the
holes on the flanges and when you set up the skins
Also, note that some of the rivets are -4. When
you're doing the drilling, if you don't go bigger
than #40 at this time, you'll save yourself some
time. You can drill those holes to #30 before
dimpling. Just don't forget.
I glued the strip on to the flanges. That'll let me
remove those clecos during the fitting of the
forward belly skin.
A machinist friend made the button at the end of the
manual flap handle and cut the slot. The bearing
blocks for this are ready now, too. The plans don't
show it but the manual correctly says to install
nutplates under the bearing block mounting angle to
facilitate easier maintenance. Since my seat rib
flanges were running low on edge distance (the
extruded angle is ample) I made a small plate to
rivet the nutplates to, and then riveted the plate
to the frame. The other side is complete too.
New (March 2018) Garmin GDL 50/50R ADS-B Receivers ...g3xpert
are pleased to announce the Garmin GDL 50 portable
and GDL 50R remote mount ADS-B receivers that are
capable of receiving Automatic Dependent
Surveillance-Broadcast (ADS-B) traffic and weather.
Both units also provide built-in attitude sensors
and a GPS receiver. The GDL 50 includes a built-in
rechargeable battery which provides battery
operation for up to 8 hours. While battery and "3D"
attitude was optional on the GDL 39, these features
are standard on the GDL 50.
Exclusive traffic features such as TargetTrend™ and
TerminalTraffic™ further enhance the ADS-B traffic
picture and are unique to Garmin products.
Wireless and hardwired compatibility is provided for
G3X™ Touch, the aera® 660 and aera 795/796 aviation
portables, as well as wireless connectivity with the
Garmin Pilot app, giving customers access to a
full-featured suite of weather products, ADS-B
traffic and more using a single device.
Each of these receivers supports 2 wired (RS-232)
display connections and 2 wireless (Bluetooth)
display connections for a total of 4 display
One of our most popular G3X Touch installations is
one with dual displays, and with the GDL 50R/51R/52R
we can now hardwire the RS-232 interfaces to both
displays, and leave the 2 wireless interfaces
available for portable units.
If you already have a GDL 39 interface mount/cable
for your Aera 660/795/796, you can plug it directly
into the GDL 50/51/52 since these units use the same
connector/wiring as the GDL 39 for power and data.
The GDL 50/50R are the latest additions to the GDL
50/51/52 line of ADS-B and SXM traffic/weather/music
GDL 50/50R with ADS-B Traffic/Weather, attitude, and
GPS (Availalble now for $849)
Trying to wrap my head around this .. p45-05 fig 1 ...bkervaski
On page 45-05, fig 1, the exploded view shows an
inside corner line that calls for an angle that
doesn't make sense to me.
I'm looking for some clarity, as this cut would seem
to result in a triangle opening in the cowl and
omitting it will have both cowls mate evenly.
Confused. Edit: I found this pic (not mine,
it's on E's site). This is correct? Is there an
obvious reason for the triangle cut-out I'm missing?
Stress relief perhaps?
Fiberglass Painting Tip ...Carl Froehlich
Don’t forget fiberglass and ultraviolet light do
not mix well. Put something on it.
This is what I do for flying before final paint:
- Prep all fiberglass to fill pinholes per the Van’s
- White two part epoxy primer on the inside of the
cowl (e.g. PPG DP48LF). Two coats. Do this before
first engine start.
- Van’s stick on aluminum heat shield on the inside
of the cowl in the obvious places (check for
discolor after the first few flights and add as
- One coat of PPG epoxy primer on outside of the
cowl and all fiberglass.
- One coat PPG single stage paint in your choice of
color on top of the primer. I find a medium blue
goes well with the rest of the plane in bare
- Anything you can do to prep the glass will be
appreciated by your painter (especially if that
painter is you). He might even drop the price a
little as he’ll see the PITA fiberglass prep is well
started. The primer and top coat paint will also
give the paint guy material to block sand - that
will only improve the final product.
- Even though you plan on painting right after the
flight test program, odds are you will be flying
like this for some time. The simple extra step of
adding a coat of color on the fiberglass will make
it look worlds better.

We've had some
damp Wx lately here around the 'ol Van Cave, but by dumb luck
there was a gap between rain bands when I pulled into the airport
Wednesday morning. My planned 45 minutes on the treadmill went
out the window. As it should.
(15) TnGs later I felt much better. Didn't have the ceilings or
clear skies to venture beyond the pattern, but it was plenty fun to
just work on technique.
Then the rain started...and it didn't stop for the rest of the day...and
I was OK with it.
So much OK I forgot to do the March wallpaper calendar. Tomorrow I
promise, he says sheepishly.
RV-14 Milestone ...control
Standing on wheels...
I received a text from my 25 year
old daughter this morning asking if I would have the
40 hours for my phase 1 flown off by July. I told
her I have about 25 more to go before I would be out
of phase 1. Circumstances, weather, wind and the
distance to the airport have hindered the progress
of getting those hours flown off. She said she was
asking because she was wanting to take the time off
from work so she and I could fly up to Oshkosh for
Airventure together. She and her husband moved away
from us this last year and its an 7-8 hour car ride
each way from Kentucky to her home in Springfield
MO. I figured its about 3.5 in the RV one way. I
know her mother is wanting those hours flown off as
well. I don't think she (my wife) was a big fan when
I started the project.

RV-Lancair Brotherhood Day...2/27 entry
Grand Strand Today
Expanding our range, Darwin and I flew 1+30 From AVL
to CRE (Grand Strand AKA North Myrtle Beach) today
for some fresh seafood. Darwin left first and I
never could catch him in my Lancair. I had him 10
miles in front on my ADS-B screen the entire trip.
Those RV-4s are fast! Our ground speeds were roughly
170 Kts. After landing, we both bought gas and then
took the courtesy car to Rockefellers Raw Bar for
lunch. I burned 20 gallons out and back so this
truly was a $100 lunch.
Full serve $5.25 per gallon at Grand Strand, but
hey, we're rich playboys, right?

A Huge Thank You
A very nice secret Santa sent me a new coffee
table book by Piers Bizony called 'Moonshots'.
No note...no card...it just arrived at the door.
Thank you very much, and you hit it out of the park.
Cameras and spaceflight...two huge non-RV interests
of mine. Starting the read took up most of my
evening last night, and I suspect many more to come.
