Diagonal Away from Home ...Capt Sandy
We were on the taxiway, waiting clearance to take off.
The flaps were up, the canopy closed. The long, asphalt
runway stretched off to either side. I had my
sunglasses and iPad. Bright October sun warmed the
cockpit. I was happy I’d worn a t-shirt. I was wearing
the pink Love at First Flight shirt Roy bought for me at EAA
Airventure. It felt appropriate for the first flight of our
open ended journey.
Safety Pilot Ballast
A local at our field is going for his instrument and
needed a pulse in the other seat. We have a two day
window around here of pretty good weather so sure!
Logged 1.4, 1.3 under the hood. Hand flown.
Three approaches (KGLE RNAV 18, KLUD RNAV 17, KLUD RNAV 35)
and some around-the-area to round the hood time up to 1.3.
All in all not a bad way to spend a little time before lunch
- I got to enjoy the sky instead of gauges <g>. I got
some ground tracks so I would have some news for the site,
but when I got home there was plenty of news to choose from.
Since I already had 'em, six grabs from the morning starting
HERE. (opens new window) Winds ~20kts from 270
Seemed like everyone and their cousins were in
the air around N. TX Wednesday. In the teardrop turn
at HIRGO (KLUD 35) we had a helicopter two miles behind us
with the same plan, and another plane on the RNAV 17 - clear
skies, all planes on the scope and everyone talking.
Fly while the Wx permits <g>. Good time.
KLUD RNAV 17, then turn around and RNAV 35.
Does Anybody Else Do This?
I have a skinny, long funnel that allows me to leave the
dip stick in the fill tube. You have to pull the
dipstick out a bit, but you don't need a rag. Lazy I
know... Don't know where I got this funnel.
Maybe someone left it here.
Lifter Failure ...RV8iator
I have (had) a Titan DIOX370 on my 8. Great engine and
ran trouble free for 5 years/ 950ish hours. Started burning
oil like crazy but everything else was right where it should
be. Good compression, clean pipes and plugs but dirty oil
and using a quart about every 3 hours like a switch was
flipped. Found a collapsed breather hose, replace and
thought I was good to go and lucky that the crank seal
stayed in. Talked to engine shop and thought I had glazed
cylinders or just broke a ring or any other myriad of things
that can go south in a cylinder, so off to JB's for a top
inspection and top overhaul as required.
They pulled a cylinder and found this..
you can see how the lifter is just coming apart and the
scored crank in the background. This is lifter part number
7287R and it seems these came from a batch in late 2012ish
that may have been produced with improper hardening done.
and this. You can see how the cam lobe is chewed up also.
and this. Another view of the top of the lifter. You can
see how clean the inside of the engine was.
It has been five years and 950ish hours since new. I have
never gone more than 2 weeks between flying, usually much
more frequently than that, changed oil and filters
religiously every 50 hours at most, sometimes at closer
intervals and used CAM GUARD for the past 3 years since I
got out of flying shows very, very regularly.
I'm posting this just as a heads up that if you have an
engine from this time frame, really watch those filters at
oil changes. Mine went from clean to full of very, very fine
black dust that was not visible, but a magnet picked it up
after the filter was washed and dried. This happened very
fast once the metal started circulating around.
This is not meant to be any kind of negative thread, just a
heads up and a reminder to really, really check those
filters when changing the oil. There were warning signs to
me in the oil consumption and I just happened to have the
filter laying in the trash from the change preceding this
one and after I washed the mesh and ran a magnet over it I
found a little of the ferris metal there. I'm sure going
forward I will be much more diligent when inspecting used
filters. Absolutely nothing visible, but the old magnet
found it. If your engine was produced in this time frame, I
would keep an eye out.

Crack in F-01447 baggage floor - what to do? ...iamtheari RV-14
I'm working on the window. That seems to be going okay,
but one step involves marking from the inside where the roll
bar brace brackets interfere with the aft edge of the
plexiglass so you can trim it to fit. I did that step and it
all went well, but I was not 100% happy with the centering
of the window, so I did the whole thing over again. In my
second attempt, I was kneeling on a stack of towels on the
baggage floor and felt something give.
The result is a dent in the F-01447-L baggage floor just
behind the hole where the rudder cable passes through and a
crack from the inside corner up to a point next to (but as
far as I can tell, not intersection) the rivet on the
innermost of the K1000-08D nutplates. Pictured below with
lots of bright light to make it look as bad as possible. The
dent is enough that the F-01440 seat ramp has a slight gap
in between that nutplate and the next one outboard, but it's
not very bad.
I am worried about the crack. All advice is welcome.
Replacing the baggage floor, while technically possible,
would be a real headache because it would also require
removal of the baggage side walls and rebuilding of the seat
bottom hinges, plus about 10,000 LP4-3 rivets, 4,000
nutplates, miscellaneous other work like redoing the baggage
tie-downs, and painting the interior on that side all over
again. But if replacing it is the right thing to do, it's
just a few dollars in parts and a few dozen hours of lost
Here's my shame, bare for all to see

First Flight ...j-red
I believe there is a law that states RV videos
must be accompanied by music from the Top Gun
soundtrack, so I've obliged.
First flight was a thrilling experience! After
literally jumping off the ground, the plane flew
flawlessly. Left wing was a little heavy, but
nothing the trim couldn't handle. Flight was 30
minutes, directly above the field at around 3k', and
mostly at 75% power to seat the rings. Winds were a
little gusty up high, and it was overcast, but all
was calm on the ground. I did two stalls before
coming down to confirm the airspeed indicator and
returned for a pretty smooth landing.
Couple of squawks included the flap circuit
blowing at 20* down every time. With the VP-X, it
can be reset, would retract fine, then blow again at
about half-flaps. Worked fine on the ground. Turns
out, one of the plastic covered spade connectors I
used to connect it had pulled out slightly and would
contact the flap motor at about that position.
Reconnected it and taped over both wires then
secured them so they wouldn't move like that again.
The landing light circuit also blew. Turns out it
just needed to be set at a higher amperage in the
Finally, I landed and found a pretty good oil slick
dripping from the lower cowling. After plenty of
cleaning and ground running, it became apparent that
the oil temperature probe gasket had gotten cocked
when it was put on. Gasket was replaced and is
holding and dry. There is some oil up front that
looks like it might be coming from one of the
smaller through bolts that doubles for retaining the
hall effect sensor for the CPI ignition. I'm going
to try some wicking locktite and see if that helps
Aside from those minor little things, she runs
great! 75% power resulted in about 165kts true
without wheelpants, and the climb is unbelievable.
Third flight occurred this morning and with an OAT
of about 35 degrees the initial climb rate was about
2500fpm! Ran for 30 minutes at power, then practiced
landings at KGED. I'll say this: paved runways are
definitely harder to land on than grass!

all the help and support along the way. Keep

Control stick wiring ...krhea
I am upgrading my control stick to
tosten Cs-8 and am confused about the digital input
output wiring. I am adding the MGL n16-V16 radio and
a CS-8 stick grip. I built a small schematic at this
I just cannot wrap my head around
the ptt going to audio ground at the radio and the
other ptt switchs grounding to power ground. Seems
like i need to take the cs-8 apart and add another
wire for the ptt trigger?
Flap Control Bracket ...NorthernRV4
So I made an error when I laid out the rivet spacing
for my inboard rib flap rib. Instead of email@example.com"
rivets I laid out firstname.lastname@example.org" spacing. Unfortunately I
didn't realize I had made the error until the
everything was drilled so now I'm looking for some
advice. Due to the blind access, these rivets must
be pull type and the plans call out CS4-4 carbon
steel type rivets. I could drill 2-3 extra holes at
5/8" spacing to the current ones or would a stronger
rivet like a Cherry Max be a sufficient choice here
instead of the CS4-4? The loading is such that the
bracket pushes on the inside of the rib flange when
extending the flaps so the stress on these rivets is
only when the flap is retracted up against the
fuselage. More likely the worst stress they would
see is if someone accidentally stepped on the flap
(had to be the port flap too ) their weight would
put these rivets in tension, I cringe at the thought
of it though for various reasons.
Electrical Issue - low battery ...Indwarrior
I have been seeing a repeated
problem with my electrical system that I am trying
to figure out. Some things to know:
- I built the plane and designed the wiring system
based on the Z-11 diagram.
- It has worked well for 300 hours
- engine is an O-235
- 40 amp B&C alternator with 300 hours on it
- B&C LR-3 voltage regulator with about 30 hours on
- EarthEx ETX680 battery 300 hours as well
- Electronics International Volts/Amps meter set up
in a LOAD Meter arrangement with matched EI shunt
- very low amp draw electrical system - about 10
amps with everything turned on (VFR panel, led
I have noticed my battery voltage dropping when it
has not been flown in a while.
EarthEx says either I have a parasitic drain going
on when the master is off or I have a bad battery.
So far I have not had the time to trouble shoot what
might be draining the battery. I do have an Always
On bus for LED cabin light, USB port and possibly
other item that I cant remember right now.
My normal/average total amp draw in flight is around
Yesterday I checked the battery with a portable amp
gauge and it was reading 12.9 amps - below the 13.3
that is typical for this battery.
The engine started just fine and I did a short MX
flight directly over the airport. For the 10 minutes
I was in the air the amp meter was reading about 25
amps, though this was varying up and down by an amp
I have never seen this high amperage (alternator
output) before. I have high and low voltage warning
lights and a stuck starter light. None of the
warning lights lit up during the flight.
So, is the 25 amps I saw simply just normal? Is this
a case of the alternator charging a low battery?
Again, the max load from my electrical system is
around 10 amps, and everything was not turned on
during the flight.
I know I need to check the system for parasitic
drain but right now I'm just trying to understand
that my charging system is doing.

Battery box too narrow ...dbaflyer
Went to install my battery tonight
and it would not fit. The left side started to slide
in, but the right side would not go. Removed the
battery box from FW and measured it. The right side
is only 2 and 29/32nds. This is a van's battery box
that was already put together. Just needed to rivet
on the angle on either side. I see my only
alternative to cut the right front corner, widen it
to the right size and install a piece of angle on
the outside of the box to hold it in place. Anyone
else have this issue? Seems odd to me that the part
would come undersized.

Soft Spot Plenum Lid ...DanH
RV-8 builders know stuffing an angle valve Lycoming into
an RV-8 cowl results in very tight engine to cowl clearance
above the front cylinder corners, and down the left side. It
gets worse with a plenum lid, a classic case of stuffing six
pounds of stuff in five pound sack.
My plenum lid has routinely bumped the inside of the upper
cowl. If I look close, I can see some fine spiderweb cracks
in the cowling clear coat, so if allowed to continue surely
it will develop an ugly spot. In recent times it has not
been bumping so much, but that was because the mount
isolators were sagging. With new isolators, it was time to
fix the bumping.

RV-3B Status Report ...David Paule
The RV-3B has a depression in the seat pan to accommodate
a large pilot, which I’m not. Typically, the builder adds
foam to fill the shape. I’ve heard that some of the seat
cushions get pretty heavy.
So I’m making a wee change in the seat structure. This
picture shows both the existing ribs and one of the added
webs. The fuselage is on it’s side here, in case you’re
wondering why the photo is odd.

Update on Lord Motor Mount Thingy ...DanH
"...The answer seems to be ....both.
With the VIP acro mounts, the airframe shake below 2400
felt like an out of balance prop. Vic had done a dynamic
balance not long ago, before I discovered dripping silicone,
and realized how far gone my Lord mounts really were. With
new VIP acro mounts installed, we were both curious about
how failed Lord mounts might affect the dynamic balance
process. If one or more gel bags and center spacers were
against the inner steel ring, would it skew the dynamic
Answer...apparently yes. I flew over to Fresh Fried Chicken
where Vic and I repeated the balance done just a few months
ago. Getting down to 0.01 required the removal of a #10
screw, washer, and compact nut installed when we balanced
with bad mounts. IPS immediately dropped below 0.4 (or maybe
it was 0.03). A washer or two in the right place dropped it
to 0.01. The lesson, now learned, is obvious; check your
mounts before balance.
However, when flying home, there was no significant
difference in cockpit feel. Pulling the prop to down to
around 2300 would still make my sunglasses dance. Ok, fine.
If it ain't balance, it must be resonance.
As previously noted, the VIP acro mounts are simply two thin
isolators and a slightly different internal bushing length.
I called VIP, and they were willing to sell me the thick
isolators and the correct bushings, since I already had
plenty of thin isolators. The resulting thick-thin set is
exactly what you would get from Vans or Aircraft Spruce.
Blocked out the day Saturday and got 'em in there.
Drum roll please; a short test flight yesterday confirmed
the return of good vibes. It's been a long time since I had
new Lord mounts, so a direct comparison is hard to
judge. There is no objectionable behavior with the
VIP mounts; I can pull RPM down with fairly high MP and the
previous large amplitude shake is gone. I did notice one
difference between the VIP and Lord mounts. With the Lords,
I recall pulling 3G would cause a noticeable change in
engine sound and feel. There does not seem to be any change
with the VIP mounts. I assume G would push the Lord gel bags
into contact with the rings. I do not know how long ago I
noticed the sound change with G; could be after they had
sagged a little.
I'll fly the new isolators a while and eyeball them for sag.
Given this is a return to the "one size fits all" isolator
set, I'm interested to see if the large engine actually does
shorten isolator life. Seems logical that a 320 would not
load the isolators as much as a 390. ..."

Alternator pulley suddenly rubbing against bottom cowl
This morning during the preflight I discovered a little
crack in the bottom cowl of my RV8. Furher inspection
revealed that the alternator pulley touched the inside of
the cowl and rubbed through it.
I have been flying for app. 70 hours since a prop overhaul
and haven't noticed this issue before.
But last week I had the cowls off, did a oil change and put
them back on, so I assume that putting the cowl back on was
the moment from wich the pulley started to touch. I didn't
touch or change anything else.
I'll repair the little crack with a bit of glass and a drip
of touch-up paint on the outside.
But does anyone know what I might have done wrong when
replacing to cowl or what else might I have to look at? If
it happened immediately after replacing the alternator or
work on the prop or then that might be the cause. But I
didn't touch those.

OSH Event: 40 Years of the RV-4 at AirVenture! ...Greg @ mothership
Heading to OSH this year in your RV-4? On the
fence? Need some fresh motivation to finish that
18-year-old project? Well - maybe this will push you
over to the "I'm going" side!
The RV-4 is officially 40 years old in 2019, and
we've be in discussions recently with EAA because
they'd like to work with us -- and all of you -- to
see if we can have a special RV-4 parking area and
do some other stuff to celebrate the RV-4! We'll
update here as we nail down details, but in order to
get started we need to line up some helpers!
We're in talk to try to arrange RV-4 participation
in a "homebuilt review" style fly-by, and some other
possibilities. EAA has said they'll help arrange a
meeting place for a get-together if we like.
Ultimately, we are looking to the RV-4 community to
see what you'd like to do! These things can't happen
without community involvement to help drive it, to
be sure. So -- If you're interested in participating
or helping coordinate some part of this, let me
From the mothership, our working plan right now is
that Van will present a forum covering the history
of the RV-4, where it came from and the role it
played in propelling Van's Aircraft in its early

some last minute items that have been hanging onto

forever. All were minor things, like painting the
glareshield flat black, sticking on necessary
placards, making sure the jamb nuts on the elevator
hinges were tight , etc. Fortunately we've had a
string of warm days recently, and so a sunny 75
degree day a couple of weeks ago presented the

Homemade jack pad
Inspired by the cool jackpads from Winter, I made my
own out of 1" X 1 1/4" 6061 T6. I did the whole deed
with out much more than a drill press, carbide burr,
and a miter saw. The mounting holes are 15/16" OC
and I used AN4-21A bolts. I had to make one spacer
at about 17/64". The AN4-31A bolt only has about a
half inch of threads so I reamed the hole halfway
and tapped the rest. That way the shank of the bolt
is in shear. I made a sleeve out of 3/8" OD 4130
reamed 1/4" ID to take advantage of more bending
resistance and so I could torque the bolt into place
for jacking. The pad weighs less than 2 oz. and fits
under the wheel pant with the jack bolt removed. I
bought an aluminum Porsche jack on Ebay which weighs
less than 3 lb. I'm gonna throw that in a bag for
the baggage compartment on cross countries. With a
spare tube and a CO2 inflator, I'm ready for tire
Odd Brake Failure ...Tim-NJ
After some routine maintenance which did not
include anything at all with the brakes (I did an
oil change), I uneventfully taxied out to the runway
for a short test flight. Winds were something around
12G18 and coming from a direction that favored the
far end of the runway when coming from my hangar.
The taxing was uneventful. I line up and go full
throttle when I do notice some unusual squirreliness
staying on the centerline that I dismissed as xwind.
I flew for a half hour and landed only to find out
my right brake was completely out. Lucky for me the
runway was 3500ft and a the last third is uphill,
2nd stroke of luck the FBO was a left turn I got a
tow back to my hangar and found this! I'm wondering
if I picked up some FOD on the taxiway or runway?
Test Data!!!- Anatomy of a fuel pump, part 3- ...Hartstoc
Now that we are getting comfortable flying
“electron-dependent” aircraft and have powerful,
lightweight lithium batteries at our disposal, I’ve
been thinking it is time to find a way to SAFELY
eliminate one of the last vestiges of the magneto
era- the engine driven mechanical fuel pump. There
are a lot of really good reasons for doing this that
I won’t go into here, but the challenge in making it
possible is to find a reliable electric fuel pump
properly matched to the task. This thread documents
my successful search supported by real data, and
I’ve generated accurate performance charts under
real-world conditions for three pumps.
Thousands of airplanes already sport electric boost
pumps that seem to work well, but on close
examination few of them make any sense at all in
this context.Two problems with most pumps currently
in use is that they generate flow and consume power
FAR IN EXCESS of our needs, and many feature
continuous short-loop recirculation of the vast
majority of their output back to the pump inlet.
This is no big deal for backup pumps used
intermittently, but wholly ill-suited to continuous
operation in a twin-pump setup with no engine driven
pump. Some are also quite heavy, bad news with two
installed. For continuous operation, return lines to
the tank in use become mandatory, and the pump must
operate efficiently to minimize electrical demand in
normal operation and maximize range on battery power
should the alternator fail.
A plethora of choices exist in the 500-1,000 HP
range for auto racing applications, but precious few
really make sense in the context of typical RV’s.
Also, I’ve discovered that published performance
data for pumps is often not detailed, accurate, and
reliable enough to allow intelligent selection, and
these do not take into account system-wide
resistance that must be subtracted from the
performance of the unrestricted pump.
I decided to build this test rig, shown here
collecting data for one of the Walbro pumps. It
incorporates pre- and post-pump filters and enough
lift, bends, turns, and manifold reversals to
roughly mimic the aft-of-firewall dynamic flow
restrictions of a typical RV installation. Here, the
return line is closed off, and “engine” output,
dialed-in at 30PSI resistance, is being shunted to
the flow-measuring vessel.

Updates to RV-12/RV-12iS publications and plans - Feb 14 2019
As happens from time to time, we published a few
documentation updates for RV-12 and RV-12iS

Van's website. All of the changes published today
fall in the "Revisions and Changes" publication
category. You can also sign up to receive periodic
notifications of changes we publish via the signup

The following documents were updated for both the
"legacy" RV-12 and the RV-12iS.
•Pilot's Operating Handbook
•Flight Training Supplement
•Production Acceptance Procedures
In addition, the following documents/plans pages
have been updated specifically for the RV-12iS:
•Section 28iS/U and Section 35iS/U - reflects
changes to parts and procedures related to new,
improved gun-drilled gear legs
•Section 51AiS/U - Placards and Certification
•Section 03iS/U - reflects an addition to the
builder's supplies list
•Section 01iS/U - minor changes plus DWG 1 and DWG 2
(the three-view and cut-away view drawings) have
The following section has been published and is
specific to the "legacy" RV-12:
•Section 35 - reflects changes to parts and
procedures related to new, improved gun-drilled gear
Note: The RV-12 gun-drilled gear legs are a revised
part, which integrates brake plumbing and removed
the need to run a tube on the outside of the gear
leg. This is now the standard shipping part for all
RV-12/12iS aircraft. In the event one needs to
replace a set of original main gear in the future,
different attachment hardware will be used and Van's
will have a kit available for doing so. Other than
the integral brake line, there is no difference

RV-12 Crosswinds Update...Ron Gawer
I wanted to share my experience early this
morning as I’ve gotten more and more XW experience
in my RV12.
Today I was able to explore what I think are the
upper boundaries of XW’s in my 12. I had 160@41 KT,
which presented about 35KT HW and 20.5KT XW in the
pouring rain this morning. Aside from being crabbed
about 15º to the right and just over 30KT ground
speed, it was pretty much a non-event. I find that
the rudder has plenty of authority to crab down to
the runway and then kick the nose around into
alignment and set the upwind gear onto the runway. I
then let the left gear down to the runway, set the
nose down and then pretty much came to a stop after
that without any brakes. I had to power up to get to
the turnoff and then had to use power and brakes to
finagle my way to the tie-down.
My fellow commuter was laughing and joked that it
seemed like an “austin powers” getaway scene taking
so long to get to the runway.
All in all, I’d say that’s about on verge of a limit
for the airplane. I think it could handle a couple
more knots XW for the landing, but taxiing sucked.
Afterward, I noted that the rain did an excellent
job shining up the aluminum.
Separately, there was windshear at 2000’ indicated
at 55KT; coming down through that was, shall we say,
“bumpy”. 90KIAS worked well, and the stick and
rudders got a great work out too. The TAF for
tomorrow is a little better with less rain, should
be another fun ride.

First Flight(s) done! ...AviatorJ RV-10
Successfully completed Flights #1 & #2 in N10JW
today! I defined success as flying the plane and
nothing leaking or falling off!
I did two shortish flights. This first was about 25
mins in the air doing about a 5 mile box around the
airport. The second was a quick 15 minute flight
around the pattern once. I did these as 'shake down
flights' with my only concern being checking for
leaks and validating the wings weren't going to fall
Really the only issue of concern was my oil temp. On
the first flight as soon as it pushed over 220 I
decided to land and it was 243 when I landed. After
a hour of engine cool down the 2nd flight it rose to
220 fairly quick so that's why I only did one lap
around the pattern. I talked to Barretts and they
gave me some places to start troubleshooting. Hope
to do another flight next week!

Van's web orders placed Feb 13th - Please check for confirmation
We've had a couple of limited "growing pain" moments
with our web store since we launched the new site.
The good thing is we will be replacing the online
store later this year with a new, much more modern
platform. The tough part is there are some orders
placed on Wednesday (Feb 13) that may not have been
completed due to an error that was not obvious to
the person placing the order.
If you placed a Van’s Aircraft web store order on
Wednesday, February 13th
2019 between 4:00 a.m. and 1:00 p.m. Pacific time,
we ask that you please check your email to determine
whether or not you received a confirmation of your
order. If you placed an order between those times
but did not receive a confirmation email, please
either call our office and speak with the Order
Team, or you can simply resubmit your order online.
Confirmation emails can sometimes take 15 minutes or
longer to arrive.
What happened: Due to a system processing issue,
some orders submitted during that time frame could
not be completed. An error message was displayed to
the person placing the order, but that error message
was not explicit in stating the error, and some
customers may not have recognized that there was an
error with their order.
The issue has since been rectified and testing
performed, and web orders being placed now are being
processed as expected. If you placed an order
outside the hours listed above, or if you received a
confirmation email for your order, there is no need
for you to take action.
Thank you, and please accept our apologies for any

Skyview Checklist Maker ...Dgamble RV-12
I wasn't satisfied with Dynon's method for
creating custom checklists so I started working on
an alternative. It's pretty far along and I have
created a nice RV-12 checklist with it, but I'm not
sure what to do with it now, if anything. Here are
some screen shots to give you an idea as to where I
was headed with it
It has not been tested beyond my own PC, but I do
have a self-installer that should work on any
Windows machine. I really have no idea what to do
with it at this point. Sell it, give it away, just
forget about it - it seems a waste to only use it
for my own checklist, but I'm reluctant to get
pulled back into professional IT, by which I mean
that I'm not sure I want to be forever on the hook
for maintenance and enhancements.
As such, I would like to
have a handful of people try it out, see
how it works, and give me an idea as to how much
more development it will need before being useful
for a broader audience. Before doing that, though, I
thought it might be a good idea to get some feedback
on what I have done already.

Pouring Elevator Counterbalance Lead ...Bill E.
What I did..
On my -4, I made a simple wood mold that mimicked
the rib shape and depth. I took my completed
elevator, minus the weight and set up on balance
point, then filled baggie with lead shot and taped
to rib tip, adjusting amount until slightly nose
heavy (compensate for paint). I then melted and
poured into wood mold. After cooling, drilled and
counter-bored for mounting bolt through rib. Test
fit with bolt/nut while in balance jig to obtain
slight nose heavy condition. I then primed the lead
weight (rib already primed, and installed the weight
with Proseal to completely water seal the weight in
the rib. The finished product looks almost molded
in, and was painted during final paint. In the event
it would still balance nose heavy, it is possible to
drill a hole to remove weigh, then touch up paint. I
do not like the idea of a bonded or glued weight,
because if it comes loose, your elevator will likely
jam, and obviously, you risk flutter with loss of
balance, hence, mine are bolted and sealed in place.
The whole process from mold making to installed took
an afternoon at best.

Classic Aero RV-14 Side Panel Pictures ...Luke
Hello RV-14 Builders,
I'm sorry this has taken longer than I expected it
would. I've lost count of the number of major design
changes we've made, and there still may be a few
tweaks before it's said and done. That said, these
pictures should represent the final design for the
If you have questions about the side panels that
others might benefit from, please ask here rather
than calling, and I'll try to keep tabs on this
thread. I'll also start off by answering a few
questions here too:
•We are starting out with "Cabin Area" side panels
for now (that is what these pictures show). Full
baggage panels will be available. Timing to be
determined as we get further along shipping these.
•We are still working out pricing.
All of the information for the cabin area side
panels should be on our website sometime next week.
We won't be taking any orders until then.
•Other products for the RV-14 will include
Glareshield trim, and a much more basic side panel
package for those that like the more spartan look.
Timing to be determined further down the road.
•The hidden canopy latch mechanism is a custom
design to work with our side panels. It is
retrofitable. The handle will be anodized aluminum
(the mockup is a painted 3D printed part).
•The lighter area near the top is the painted
structure. All other areas are covered in our
standard upholstery materials so that they match our
seats. Colors can be arranged to your preference.
•Headset jacks are in the stock location.
•Based on past experience, we have used 2024 T3
Aluminum for the structure. This reduces weight (we
will have final weight numbers when production parts
are ready), increases durability, and aids adhesion.
The only molded plastic part is the air vent trim.
•With a few very small exceptions, there are no
•The black trim below the latch is machined
Comments and constructive feedback are welcome.
These have been a long time coming. They may look
fairly simple to the casual observer, but hundreds
of hours of design and prototyping went into these.
Hope you all like them

200kt GS Club ...bruceh
I finally was able to hit the magic 200+ Knot
ground speed on the way to the Copperstate Fly In.
This is of course only possible with a really strong
44 Knot direct tailwind, but it is in level flight
with "Otto" the pilot at the controls. The green
circle on the map is my "glide ring", you can see
how skewed it is towards the North East. At one
point I saw a 48 knot tailwind. It was actually
quite smooth all the way out to Buckeye, AZ. I
decided to enrichen the mixture a bit and see what
the true speed of the airplane could be at altitude.
My usual 6.5 gph speed is around 147-150 Knots
(LOP), so with 9 gph it was going only 8-10 knots
Bird Strike PIREP ...luca
I had to wait some months to write this story due
to some ‘insurance misunderstanding’.
It was a relaxed and calm sunny day last year on May
25. I liked to give, to our local kindly “tower girl
operator” what we call the RV Grin. So at 3 pm local
time we were in the air.
After a 30 minutes flight I was descending over the
home field at 190 Kts and without seeing nothing I
only heard a GREAT 'bang', really loud (something
like shooting with a S&W 686 a .357 Magnum bullet
w/o ears protection).
The condition of the windshield immediately gave me
the idea of what happened. Fly the airplane, stay
calm, reduce speed and power, deep breath was my
I decided to make the best of the
weather this past weekend and get a few things from
my list accomplished inside the hangar that have
been lurking over my shoulder. I have to admit to
being a bit complacent the past few years and let my
instrument currency lapse. Northern California is an
easy place to let that happen with abundant sunshine
and few reasons to feel the need to fly IMC. I used
to fly a Socata Trinidad when living in Ft. Myers
and filed IFR nearly every flight, feeling safer
under the watchful eye of ATC. Well, I finally got
my act together and practiced, re-learned, and took
a combo IPC and BFR last week, passing both. As a
reward, I purchased a second GTR-20 for my -9A. I
always said that I wanted a second comm but just
didn't get around to installing it. The threat of
flying IFR was enough to get me in the mood to dive
back under the panel and do this. So I called my
friend and patient teacher Randy Throne to arrange
some help. We updated my ELT to an ACK 406 and fixed
that co-pilot PTT that didn't work since the panel
upgrade (it helps if one actually attaches the
ground..... oops). Last, we replaced the left side
fuel sender that was going south. Everything went
together and worked right out of the box. the ELT is
registered, comm broadcasts and the PTT is happy
with electrons moving in the right direction. All in
all a very busy but successful and fun weekend in
the hangar. Thanks Randy, I always enjoy working on
the plane and learning the right way to do

Checkride this past
Friday afternoon out of KWEA. DPE Joe Johnson (card
below). Firm but fair, expects you to know your stuff.
Know your EFB app and your weather. Detail-oriented
oral w/many scenarios. The flying part was more
enjoyable - turns out 2,500+ landings in this thing is a confidence
builder. Stalls, emergency descents, sim'd engine out
180* landing, soft field, short field, spot landing, simulated fouled runway in the flare. The
flying was fun!

Thank you Mr. Johnson for a professional, well done
checkride. I would certainly recommend you to any RV
pilot that would listen. Thank you Gary Platner, RV-8 owner and CFII
rock star. Thank you
for one seriously dialed in plane. And last but not
least, thanks again to Mr. VanGrunsven for
designing such a wonderful flying machine.
Took both IFR and Commercial checkrides in the RV.
What a honor to get to do that!
It felt strange Saturday
morning (and Sunday) to not have that Oral Test Prep book in

Digging Out My RV-6 ...mbauer
Was sick last week, wasn't
able to dig out the RV after each snow storm until
Nikiski received more
snow than Kenai, it is 15.2-miles from my driveway to the
tie downs at the Kenai Airport (PAEN).
When I arrived after work yesterday, the RV was isolated by
about 10-inches of frozen snow. It rained at 40 degrees F
and then cooled down to below freezing before it started to
Only way I could move the snow was by using a metal square
tip shovel to break it up and then a plastic snow shovel to
move it out of the way. Took three hours to clear the
tie-down. Worked up a sweat wearing a t-shirt in 12 deg F

Passed Inspection! ...AviatorJ RV-10
Still hasn't hit me
yet but as of yesterday N10JW is Airworthy! She
successfully passed with no major issues. The DAR
was fantastic throughout the process, fielding the
numerous questions I had as well as help in
completing all the fun FAA paperwork!
For the actual inspection he gave me to posture of
the plane prior to coming out. Basically access
panels removed, empennage fairing no screws, baggage
panels removed but the engine cowled up. He spent
about 45 mins looking over the plane, we also
removed the cowling so he could see the engine. All
in all I had 5 or so items he wanted me to double
check and made some great suggestions.
We then went back to the heated FBO where he looked
at my build log, FAA forms and made all the
appropriate entries. He also walked me through the
special airworthiness certificate which now also
includes operating limitations. After everything was
completed and explained we took the obligatory
inspection picture and now I'm clear to fly!
Another Panel Layout Thread ...N804RV
1) I'd welcome comments and criticism on this panel layout.
This is a rough idea. All switches and circuit breakers have
not been accounted for yet. Trying to keep the 430W high
enough in the panel to clear the aft LG tower support. And,
keep the PFD nearly centered.
2) As far as keeping the PFD close to centered: Can the
SkyView 7" Classic display be configured so the the PFD is
on the right (60%), and the map on the left (40%)? I always
see the PFD on the left side of the screen.
Status Report ...KazooRV-9A
Canopy skirts are
in place! No small feat.... Friend Ken was over last
week and we put in 36 man hours total to get them in
place. I like how the instructions say, that after
all the work it took to fit the bubble to the frame
and actually achieve a rolling closure with proper
fit, that the rear skirts are the hardest part of
the canopy build. I disagree, they were tricky,,,
but not the hardest part.
AND.... Here's the long awaited first look at the
Aerotronics gauge panel sitting in place. I've
waited two years to see this little gem in the
cockpit. I'm betting the original builder (Marty
Johnson - Gone west) can see it now, and is
thrilled, he surely spec'd out a nice panel.
Good News ...vic syracuse
A couple of things I want to share:
First, our youngest son, Nick, earned his Private
Pilot's license this week. He's been working
with me in the business for a while, too. It's
really heartwarming and way cool to see your son
enthused about aviation as much as I am.
Second, Many of you may have heard by now that we
have finally opened up our new facility at Falcon
Field (KFFC). Next Saturday
(rain date Feb 23), we are going to have an open
house from 11-2, with barbecue. So if you are
looking for a place to fly to next Saturday, we
would love to see you!
We will be giving out T-shirts with our company logo
on the front and a catchy phrase on the back I think
you will all get a kick out of.
The new hangar is on the Southeast corner of the
airfield, on the left hand side as you land on
Runway 31. It's a large empty ramp with only our
hangar there now, so you can't miss it.
If you think you might make it, please RSVP to my
email. We want to have enough food.
We won't hold you to it if you don't make it.

New Plane for me
I bought a nice RV-6 this past weekend. Its a tip up
with a Lyc O-360 and FP Prop. My previous RV was an
8 that I built. Air on the ground was not an issue
with the 8....this tip up thing cooked me on the
ground at 74*F!!! it is too heavy to just ride
around while holding it open. I know there's gotta
be a better way...HAHAHA!!! please tell me the
Also, today was my first time flying it. Very heavy
left wing with full (even) fuel. My 8 had a heavy
wing and I remember there was a trick for fixing
this...as I recall I put two paint stirrers on the
trailing edge of the aileron and then used an edge
seamer to "crimp" the trailing edge..I just can't
remember which aileron to "adjust"!! Any help would
be greatly appreciated.

JDAir new Canopy Latch
The JD Air Parts tip up canopy latch
has been slightly redesigned for a better
appearance. Mechanically, it is exactly the same.
The reason for the design change is two fold. 1) The
previous version was water jet cut and then required
machining. 2) My company doing the machining looked
at the drawings and felt the latches could be
machined quicker with a better appearance.
RV7 builder Sean Blair installed one in his plane.
He had the old version and installed the new one for
comparison. He said it works exactly the same. He
will probably chime in with his thoughts and
And, in the interest of safety, we are also offering
the latches anodized red.
I thought this was important as a critical handle
for egress. I don't have pictures of the red version
but will get them on the site soon.

Aileron Bellcrank Grease ...Mudfly
I'm ready to install the aileron bellcranks in
the wings (RV14). Not sure about other models, but
the bellcrank design for -14 has a brass bushing
that is inserted into the steel housing of the
bellcrank. The assembly is placed in position and
secured using a AN4-32A. When the bolt is properly
torqued, the bolt and brass bushing are to remain
stationary with the rotation occurring between the
bushing and the steel bellcrank. There is no mention
in the plans of lubricating this rotation point, but
I was thinking it may be a good idea. My question is
what would be the better lubrication. LPS-2 and
Lubriplate 630-AA are two products that I'm
considering. It seems both may have pros and cons.
The pros for the Lubriplate would seem to be longer
lasting. However, the con would be when it is time
to replace, the bellcrank assembly would need to be
disassembled. Also, will this lubriplate break down
during the heat of the summer and drip out the
bottom? That's what happens to grease in my grease
guns out in the garage during summer. The pro for
the LPS-2 would seem that when time to re-lube, it
would just require opening the access panel on the
bottom wing skin and applying fresh lube using a
flexible tube. The con for LPS-2 would seem that it
would need to be re-applied at shorter intervals.

Legally Heating a Hangar ...mfleming
So I purchased a hangar recently
One of the improvements I would like to do is
install a fixed vented propane heater.
Because I will be renting the hangar out until I am
ready to move my -7 project into the hangar I
applied for a commercial lease. Oregon requires a
commercial lease if ANY revenue is being made off of
Anyway, while researching heaters I came across NFPA
409. This states that heaters must be at least 10'
above the wing of the aircraft.
I might get the heater 10' above the wing of my -7
but the rule says 10' above any aircraft that can
fit in the hangar (I'm paraphrasing). Not happening
I read all about portable heaters...I'm interested
in the fixed variety.
So, Do I have to comply with this NFPA 409?
What is everyone else doing with hangars with lower
ceilings and heat??
The top of my door is 12', the door opens to about
10' 8"... No way to meet the rules as far as I can

Exit diffuser on oil cooler to increase flow through oil cooler ...scsmith
I want to do some cowl work to
reduce my cooling exit flow area and at the same
time reduce overall frontal area.
But before I can do that, I have to do two other
things. One is make a seal around the
crankshaft/spinner gap. As you close off the cooling
exit, raising the pressure in the lower cowl plenum,
you want the higher pressure to result in higher
exit velocities out of the cooling exit, not just
spill out around the spinner. So I have to do that.
The other thing I need to do is
increase the flow through the oil cooler. The
angle-valve engines put a lot more of the heat load
into the oil, and efficient oil cooling is crucial.
I've been very happy with my firewall-mounted cooler
arrangement with the large 20006A cooler, I have
good oil temperatures even during a long climb at Vy
on a hot day. But as I close off the cowl exit and
increase the pressure in the lower plenum, the oil
cooler flow will decrease because of the reduced
pressure differential across the oil cooler. So..how
to get that flow back? put a diffuser on the cooler
exit. The trick is to do this smoothly enough get
good pressure recovery without a lot of length that
wouldn't fit in the cowl area. Short, wide-angle
diffusers can work pretty well. The pressure in the
oil cooler flow at the exit of the diffuser will
match the local static pressure in the area around
it. Ideally, if the diffuser is flowing well, this
results in lower pressure at the exit face of the
cooler itself. Its like immersing the cooler in the
throat of a venturi.
I made a mold out of wood, painted and waxed it, and
laid up a fiberglass diffuser. The diffuser geometry
has an area ratio of 1.45. This will also be a good
trial of the high-temperature hardener system
(3136R) I got for the Jeffco 3107 (Rhino) epoxy we
use. The diffuser was room temperature cured, then
removed from the mold and post-cured, 1/2 hr at
150F, 1/2 hr at 175F, then 2 hr at 200F. Hopefully
this will give a high enough glass-transition
temperature (T_g) for the epoxy to survive the hot
environment in the lower cowl. Here are a couple of
pictures of the installation:

Work is underway, and I’m having a blast!
Really impressed with how well thought out and
designed all of this is. It gives encouragement and
confidence in the path that lay ahead.
To the guys in Missouri, I’m looking forward to
crossing paths with you all, and getting to see your

To Mike S,
neat to connect the dots through our mutual friend,
and thanks for the well wishes as well.
I’ve one small question… one of the photos is a
really close up shot of the small bend that’s to be
put on the trailing edge of the rudder skin. Does
that amount looks about right? That seemed to be
about how much I did on the small practice kit that
was a 1 foot aileron section, and it seemed to turn
out ok. But I’d rather not glue the trailing edge
together, and have it curl up during riveting.

New steering link geometry ...scsmith
of you will have seen the thread that I started several
years ago after a surprise groundloop occurred in a strong
starboard cross wind when the steering link unexpectedly and
That thread stimulated a lot of good discussion on several
related topics, one of which is the asymmetry of a "rocket
link" steering link in the release points when steering left
and right. The asymmetry is caused by the angle at the
rudder horn from the rudder hinge axis to the attach point
for the steering link being a different angle than the angle
at the steering arm from the tail wheel pivot axis to the
attach point for the steering link.
After some discussion with Darwin Barrie at JD Airparts, he
arranged to make a modified steering arm. I spent a little
while doing some trig and analytic geometry to come up with
a length and sweep angle of the steering arm that would
produce a symmetrical release action to the left and right,
and have both directions cause release of the tail wheel
lock just at the extreme deflection of the rudder. Darwin
sent me the the new steering arm and a longer steering link
to test out. Here are some pictures of the installation.
I have not been able to fly this installation yet because of
weather, ongoing condition inspection, and some other
activities. But I will report back here as soon as I can fly
with it. I can tell you that on the ground, if you pull the
rudder all the way to the stop, and put pressure on the tail
wheel in the direction it would feel if steering, it does
NOT release. Same left and right. If you put the rudder all
the way to the stop and put pressure on the tail wheel in
the direction to make it swivel intentionally, it does
release. Same left and right.
You can also see that I
substitute a normal rod end with an AN3 bolt and AN970
washer, plus some of the rod end spacer washers that Vans
sells, in place of the integral rod end + stud that is
supplied. This insures that the rod end stays captive in the
very unlikely event that the bearing fails.
So I am pretty optimistic that this will be a nice
improvement to the steering link system for those that like
it. The steering link system is quicker steering than chains
or cables with springs and a little slack, and arguably not
as rugged as cables with springs. So there is still room for
personal preference here. But for those of us that like the
quick, positive steering feel, this new steering arm should
give you symmetrical behavior.
RVs connected people ...Luke in Italy

Status Report ...Tdeman -6
I got a deal on a
second hand engine mount, gear legs, and wheels that
came off of a colleagues RV-6. As a bonus, it had
wheel and leg fairings already installed. I decided
to see how the mount lined up with the holes that
were in my firewall already. The top two holes were
dead on, but the bottom two were both more then half
a hole off to the inside… Symmetrically, so there
was no way to realign the mount to get it to work…
Measured the mount, and it’s right to spec, so
somehow, sometime before I got it, the firewall and
weldements were miss drilled to 1/4”. Time for some
surgery to get things right…continue

Bahama trip follow-up
I just returned from
my 4 day (3 nights) trip to the Bahamas in a nut shell it
was a fantastic in every way. I began the trip fairly early
the morning of Jan. 28 and flew to Fort Meyers airport (KFMY)
where I picked up my long time friend Art Kampf. From there
we flew non stop to New Bight airport (MYCB) on Cat Island
in the Bahamas. Flight time was 2.3 hrs. Clearing customs
there was easy and took only a frw minutes plus a fee of

experimental XYZ, pan, pan.” That got their attention!
I’d used mayday two or three times in the past, but this was
the first time using pan. I was flying with a friend, and
when he gave me the controls back in the RV-9A after doing a
turn, the stick was really heavy. The elevator trim
indicator showed way, way nose down – uncommanded. And the
elevator trim switch was ineffective. After talking it over
with my friend, also a very experienced CFI, we decided this
was an appropriate PAN situation and going home right away
was the best course.
We were about 8 minutes out, about 120 knots, and what to
do? ATC offered closer airports, but home base seemed pretty
doable. But it took a LOT of pull on the stick.
The first decision was that I had him fly so I wouldn’t be
landing an out of trim airplane with really tired arms.

Keeping fuel pump cool
I've been having ongoing issues with fuel pressure
fluctuations at higher altitudes and am trying to get them
resolved once and for all. I've done everything I can think
of to keep the tunnel cool (insulated firewall and floor of
the tunnel, pipe wrap insulation around the scat tubes
there, etc.), but that hasn't helped. I'm now in the process
of moving my fuel flow transducer out of the tunnel and
instead between the engine pump and servo as the "red cube"
manufacturers suggest to avoid the possibility of the
transducer being a source of vapour lock. I've also changed
my fuel pressure sensor in case it was faulty in some way.
I'm still working on these changes so haven't done a flight
yet to see if the situation improves, but while the plane is
down am trying to improve the performance of the fuel system
as much as possible.
But something which still strikes me as "poor design" is
that when cabin heat isn't required, heat from the exhaust
muffs is directed to the area between the firewall and
engine, right where the engine fuel pump is. I have the
stainless cabin heat selector vents as well, which help to
prevent heat from leaking into the cabin when it's not
wanted, but does nothing to keep the area aft of the engine
Newbie question: skin dent
Just starting out on my VS
and I made my first (of many I'm sure) goof. Flipped VS-706
upside-down and when I wrapped the skin, the rib created a
small but visible dent. I should have known better. I'll
probably order a new skin to be safe, but would be helpful
to get a second opinion. Am I going overboard or is this
going to bother me every time I look at it?

Prop Crack Update
Closing this out, here's
the statement from the engineers at Sensenich published with
Don Rowell's perimission:
"The crack occurred at the 30% ply drop. While the crack did
not and likely would not have propagated into the spar, it
did go through all layers of the skin laminate. We cut into
the laminate at the crack location, but we were unable to
find any abnormal type of discontinuity. This is the first
like this we have observed on a production propeller blade.
It is our recommendation that we replace both blades free of
charge. At this point, we believe this to be a discrete
failure due to an irregularity that industry standard
quality control practices were unable to diagnose.
We have sectioned the blade, and will certainly continue to
diagnose and if needed correct the issue that caused the
failure. We do feel strongly that the alternate load paths
found in the blades would have prevented this failure from
As I said above, I will monitor the new blades carefully. As
someone else said, there's no such thing as a company that
hasn't supplied defective product. I expect to have a good
experience with the new blades and think that Don and his
staff have done all that can be expected.
Seen at Monk's during my
annual. Oh baby...

Continuing the annual on the RV-6. Gaskets, hoses,

be the year to replace that after a decade and change of
abuse use. It might be nice to have positive,
firm tailwheel steering again - currently it's sorta a
'suggestion'. ;^). I gave
Darwin a call and he gave me some idears.

Why I fly Young Eagles ...D. Gherardini
Gents, After reading the posts from the few who DON'T fly
young eagles, I felt compelled to tell my story. This is
gonna be long, But, I MUST tell it.
About 7 or 8 years ago or so, A fellow pilot friend of mine
from another EAA chapter called me on a friday eve, and
asked, "You are coming to our fly-in tomorrow ?" And I said,
" You bet, in fact Im gonna try and make two fly-ins
tomorrow because there is also a fly-in car-show at Pekin
Muni." He said great, would you consider doing us a big
favor and helping out with the Young eagle rides? Last year
we had over 100 kids show up and we think this year will be
even bigger, and one of our members just called me. He went
out to his hangar to check on his Cherokee and found a
puddle of oil underneath, so he has canceled, and we are
worried we wont have enough aircraft to get them all done."
Now, I had been a EAA guy for many , many years. And I
really never much paid attention to the young eagle
stuff..always too busy to give it much thought. Not that I
dont go to fly-ins. I attend a fly-in somewhere just about
every single weekend of the summer. Hated it when I missed
one within range of whatever aircraft I owned at the time.
Looking back, I was just selfishly thinking about my own
fun, and not any kids. Now this friend who called, he is a
really good friend, and as I was thinking about probably not
being able to make BOTH events if I got wrestled into this,
so I was trying to figure out an excuse to turn him down.
Anyway, because of our friendship, I just couldnt. So I
agreed. I can tell you, I flew up to their airport early the
next morning, kind of bummed out, feeling like it was a
chore I was not much interested in.
Well, for whatever reason, not as many kids showed up as
they had hoped, and after flying about 40 or so, we were
done. I cheered up, as I now was going to be able to make
that other fly-in with the car-show now. Before I left, as I
had plenty of time now, I walked over to where the pres of
that chapter, some other officers and the other pilots were
sitting in the shade of a Cessna wing and took the extra
lawn chair to jaw with them. They were all discussing what
had gone wrong, why the turnout was poor, where they spent
their advertising money, and how "unsuccessful" the event
was.They were all, "Down in the jaw" I didn't say much as I
am not a member of that chapter, and wouldnt have known a
successful event from a bust anyway.
While this discussion was going on, we noticed a woman
walking towards us from up by the area where to food vendors
and other activity was. She had a kid, maybe 8 or 9 by the
hand and continued walking our way with this somber, serious
look on her face, and kind of a "John Wayne" jaunt to her
step. Pretty quick, everybody shut up as she was definitely
coming straight toward us. When she stopped in our midst,
she said, " Excuse me men, But I would like to speak with
the pilot of that Yellow airplane right over there."..and
she pointed right at my craft. GULP...I was floored..I didnt
recognize the kid as one I had flown, but figgered I was
about to get reamed by a mad mother for something, making
her kid sick , or scared, or who knows what..and all I could
think of was..I knew I never should have done this. So I
stood and simply said, "That would be me ma'am." geting
prepared to take my licks. I think all my friends were
taking a step or two backwards as I stood..you could have
heard a pin drop.... Then she began. "MY son rode with you
this morning, and I wanted to ask you a favor, I Just didnt
see this coming. He just turned 16 last fall and got his
drivers license, and he has been in so much trouble. His
grades at school have been terrible, he wont mind me or his
stepdad. He has been in trouble with the police and he has
not come home several nights"...she continued on about the
boy, and their problems, for a bit.cant remember all she
said, but I do remember she said "he wont even stand up
straight anymore"..anyway, she continued, "But something
just happened to him, and I really think he is going to
straighten up. " When he got out of that plane he came
running to me and asked me for my phone, because he needed
to call his dad right now! " I gave him my phone and he
called his father. I heard him apologize for the trouble he
has been in, which he has NEVER done before, and when school
starts he will get good grades and he will do what Mom and
his stepdad tells him and how sorry he was, because..he just
has to learn to fly, and the pilot told him..He had to study
hard, get good grades, because Aviation is expensive, but
its worth whatever you have to pay. Nothing beats flying."
"Well, im sorry sir for the trouble, but I just didnt see it
coming, I had to go to the car and get my camera and if you
dont mind, I'd like to take a picture of you and him next to
that airplane. I dont want him to forget today."
Talk about floored..I was not expecting this. Of course I
said "yes 'ma'am, and as we started to walk towards my 912
KitFox, I saw that boy come running down from the main
hangar area where he was waiting. AHhhh..now I remember
him..he was that kid with the chip on his shoulder..acting
too cool, and like he was just gonna do but it wasnt gonna
be anything. HE was the kid that, after we got to altitude,
and asked him if he wanted to take the stick, and of course
he did..and after about one minute..he melted, and became
super enthusiastic. He got the hang real quick, as most 16
year old boys would..and as I coached him thru the next two
turns, he did really well. I felt good about it then, but I
had no idea of his troubles..and now, well, as it turns out
Thanks to his mom, two boys lives were changed that day. Mom
took her photos, and we parted. I noticed something also, as
they walked away, he was standing up straight and held his
I was immediately overcome with both pride, and then shame.
So proud I might have had a chance to change a wayward young
mans life positively, and so danged ashamed, I had ignored
this program..well..since it started. What a selfish turd i
thought of myself in the next moment. When I walked back to
the squad under the Cessna wing, The mood there was
decidedly different. I went right up to the chapter
president, and I told him. " I dont care how unsuccessful
you guys thought this event was, and I dont care if you have
only one kid come next time..you call me, Ill come and fly ,
cause nothing pays better than this." They of course were
all smiling now, in a much better mood.
I fly young eagles now with several chapters, and never miss
one. How often does a fella get a chance to make a
difference in a strangers kids life so effectively, and how
much is it worth? It does not happen of course every
time..and you cant tell what effect you have on them always,
but when you can see it..its worth more than gold. Flying
young eagles can be a Heck of alot more than giving airplane
rides, you are setting an example.

First Start After Sitting A Year. . . Ideas?
My Lycoming O-360 has been sitting for a year while the
airplane has undergone a complete panel and electrical
system upgrade. Soon I’ll be starting the engine, and I have
concerns about scuffing the cam lobes while waiting for oil
to make its way to the top of the engine. I’ve always been
told that this startup wear, particularly on what is
probably a very dry cam, is responsible for a tremendous
amount of overall engine wear.
In trying to come up with a way to mitigate the problem, my
friend wondered out loud why I couldn’t just fill the case
to the top with oil (through the breather), submerging the
cam. Then drain it all out, pull the engine through by hand
to insure no hydro lock issues, refill the case to the
normal level and start’r up.
It sounded kind of crazy at first, but after giving it some
thought, I can’t see why it wouldn’t work. I figure I must
be missing something, and thought I’d run it by you guys.
What do you think?
If you think its a good idea, I wonder how many gallons of
oil it would take to make it to the top. Also, couldn’t you
use cheaper automotive oil, since it’s going to be drained
Thanks in advance for your input!

who have lost a parent during military service.
these have been some of the best flights in my rv."
Status Report ...KazooRV-9A
Hard to believe it's been 10 months since my last
post. Here's a current photo of the Fuse. I've been
working on the Canopy since early December, it's as
difficult as many of the threads describe. Mostly
trail and error to fit the bubble on the frame and
meet the desired fit to the fuselage. I was ready to
just go open cockpit, but a friend came over one day
and we somehow got things fitted. (The windscreen is
just sitting on the front).
Recently I've redone my checklists. The plane was
first flown in 2012 and as time has passed I found I
had many little checklist tucked away in the nooks
and crannies around the cockpit. This past week I
spent some time consolidating them into three 5X11
inch laminated cards. All my information is now
handily located on the front or back of these 3
Here's the point of this post. Once when I was ready
to head home from the Petit Jean Fly-in in Arkansas,
I had my primary GPS unit go belly up. The little
bit of checking and messing with it I could do
sitting there ready to takeoff didn't yield any good
results. I had the back up nexus tablet up and
running so no issues there and I blasted off for
home. After taking off I began to think of how the
loss of the device would affect my flight. My mind
went blank!!! Here's what I did about it. While
sitting at home drinking coffee with all the time I
needed and no stress of flying a plane, I went
through each device in the plane and tried to write
a summary of each. What information I was getting
from each device, (and what information I would lose
in event of failure of that particular device),
where the device got that information from and in
the event of a failure exactly what to do about it.
I'm VFR only so this was pretty simple. The
interesting thing was the human factor that come
into play. This was no emergency at all but my mind
in the middle of it could not organize the
antenna.... it all began to run together and created
confusion in my head. Eventually I found the best
things was to ignore it and use the nexus. I did get
bummed about the thought of hand flying the 450
miles home.... (what did I ever do before I had an
AP)??? I did figure out the autopilot would still
work in heading and altitude modes.
By the way, it turns out the only thing wrong with
my primary GPS device was some corrosion on one end
of the fuse so that's why it wasn't blown and still
didn't work when reinstalled.
RV-10 Shot ...Electrogunner
Panel Progress ...ssokol
Got the newly cut and coated blanks (I ordered an
extra one for a table-top demo) on Friday. Here's a
shot of one with the switches installed:
I already had the Carling rocker switches with
the custom covers, so I decided to just push ahead
with them. Probably not as good or as small as the
locking switches, but they were paid for and they
should do the job. I think they look pretty good.
The cut-out on the far right is for the breaker
panel. Decided to stay semi old-school and use
standard Klixon breakers. The airplane already has
17 which are in good shape, so rather than trying to
go in a new direction I just expanded it a bit. The
new breaker panel will mount from behind so if I
ever want to remove the panel I can do so without
disconnecting all those breakers. Just take out the
screws and pull the main panel away.
I should have new mounts for the iPads soon. I
designed a new low-profile mount that won't take up
too much space and will make it easy to mount the
"knobs and buttons" bar at the bottom.
If you're going to be at Copperstate in Buckeye AZ
next weekend, look me up. I'll be in the exhibit
tent. I plan to have the demo system set up and

Getting my RV Grin ...Brian RV-4
Here's one way to get the RV grin. It was an
especially nice day for flying upside down.
Thanks ...first post update
Thanks for the welcome everyone. It’s encouraging
to know that there’s so much support available to
help with the build. And with very little “small”
airplane experience, it has been great to have some
folks helping me learn to flare a little lower than
30’ and teach me what a magneto does. Anyone wanting
to visit CYQA, just let me know your plans. If I’m
not on the other side of the planet working, I’ll
happily meet-and-greet any fellow RVers. It’s even a
port of entry for any Americans who want to take a
quick trip across the border. I’m excited to be part
of the RV club.
RV7-A model: Access to torque landing gear mount hardware
Looking ahead in the plans, us -A builder
eventually need to install the WD-721 landing gear
mounts against the F-704 center section bulkhead
with bolts on the top and bottom of the mounts. Once
the bottom skin is riveted on, getting good access
to those bottom nuts will be challenging:
I will be able to get a long skinny wrench down
there, but not any torque wrench I've seen. Before I
button these bottom skins up, is there anything I
can do to make this task less of a P.I.T.A. later?
Is it acceptable to measure/set the torque on the
bolt sides instead of the nuts for these?
I decided to install the F-663 control column mounts
to the bulkhead before riveting the skin for this
reason. But I don't think it would be possible (or
wise) to install the gear mounts early too.
RV-8 - #83674 - N8SA ...update
I am building a RV-8 and have reserved the tail
number 8SA. I have been documenting the build so far
in time lapse video on YouTube. The Horizontal Stab
and Vertical Stab videos are just the time lapse
video, however moving forward I intend to try and
make the videos a little more interactive and
informative for those that wish to follow along in
my build. This is the first plane I've build and
have so far learned a ton, with plenty more mistakes
to go, I'm sure!

The importance of Pie Insurance ...Capt. Sandy
Aviation Tales for Cold Winter Days, part two,
where Jim continues his story, and the importance of
Pie Insurance comes home:
....Past the playground and the fuel pump, a fellow
in a brown flight jacket slide open a hangar door
and pulled out a navy blue bi-plane. A young couple
stood nearby, waiting for the ride of their lives.
They’d see the sparkling waters of Puget Sound and
the jagged peaks of the Olympics from a vantage very
few get to see. Their flight would be thrilling, and
I hoped for them, joyous. But it wouldn’t be even
half the joy Roy and I, and others of our aviation
tribe experience. It wouldn’t have the same joy,
because their flight doesn’t carry with it the hours
spent in a airplane hangar pounding rivets, or
studying weather and courses or learning how to look
up that one radio frequency you can’t find to get an
IFR pop-up when you’re going to be in the clouds
like it or not...
Moxie Gets Her Wings ...petehowell
You might have heard there is an Alberta Clipper

morning, but no wind and lots of sun. Flight time!!!
-3B Status Update ...David_Paule
The strip for the Mil-Spec quarter-turn fasteners
for the top of the cowling now has a pattern, not
shown. I had a bit of aluminum for that, but it’s
one inch too narrow, since I need to allow for the
semi-conical shape of the thing. New piece on order.
Next, I figured that this was a good time to make a
pattern for the baggage floor. The piece of aluminum
supplied with the kit has a curious shape, and the
cut-outs for the flap torque tube arms looked large
to me. That plus Ironflight’s comment about needing
to make a pattern for his, all combined to say make
a pattern. Don’t just start cutting.
And a good thing I listened, too. I found some
white poster board at the hardware store and dove
in. Immediately, it was apparent that there was no
way it would fit into the baggage compartment as a
single piece of card stock. I cut it in half. It was
then difficult to put each piece in by itself, but
eventually, I got both sides trimmed. And more card
stock taped on, and trimmed again. Kind of fun,
working that way, but then elementary school
subjects sometimes are.
When I finally got both pieces in together, and
taped back together, the difficulty of putting the
pattern in or removing it returned. And what about
the final skin?
I temporarily installed the flap torque arm assembly
and marked, generously, lines around the arms. After
removing that frame and the pattern, I then laid out
the cut-out from the plans. You know, it’s a better
fit than I’d thought. But a tweak here and another
there, and I was able to refine the cut-out
somewhat. And, remember this, it was now easy to get
the pattern in and out. While it might be wishful
thinking, maybe the baggage floor will go in
Here’s a pic of the pattern in place, but not the
flap actuator tube. At the bottom cut-out, you can
just see the plans version of the cut-out at the aft
end of the hole. Yes, there's plenty of room for
working at the pushrod.
I’ll probably do some additional minor trimming
before I cut metal.
On the far right, you can see that the halves of the
bulkhead top are unconnected. The splice plate is
under that bit of blue tape. That'll be part of the
aft tailcone skin project, by and by.
Mystery Nutplates and Other Holes ...iamtheari RV-14
I'm nearing the end of the fuselage kit of my
RV-14, and I've also been working on the finishing
kit. I don't have the wings yet. I'm saving those
for last. Along the way, I've run into a couple
mysteries and I'm wondering if anyone knows the
Mystery 1: On page 10-12 while building the tailcone,
there are two K1000-08D nutplates installed on the
top flange of the F-01406B bulkhead. The F-01406F
baggage bulkhead corrugation covers this area up in
section 42. In between those points, I haven't found
where anything gets screwed into these nutplates.
Mystery 2: The left side of the flap motor cover
(part F-01445B-L) has two openings along the aft
edge. What is their purpose?
The two that are in focus, with their rivets
half-painted. (Note that I added two nutplates to
the battery angles for a different reason. I'm
talking about the two that are actually called for
in the plans, on the upper flange of that bulkhead.)
Alternator Question ...KRviator
Following on from Dan's issues - and rather than
start a new thread - I thought I'd seek the
collective help of the VAF Brains Trust on a nearly
For the last 20 or so hours, I have been trying to
work out what is causing my alternator to be
constantly hunting in output. The alternator is a
single PlanePower FS-14B, one of those
internally-regulated ones that mounts on the vacuum
From my "Running a tank dry" video, it also shows
the problem I'm having, with the voltage and
amperage fluctuating between 14.5-14.8V and 8-16
I flew again today after running a series of
resistance checks on the B-lead connections, the
master contactor connections and amp shunt fittings,
all were secure and no variation to the resistance
was shown during the tug tests. I'd previously
removed the 3-pin plug and noted a small amount of
corrosion on one of the female pins, though nothing
I'd class as troubling. Today, I removed the 3-pin
plug and also removed the 2 female pins from the
housing, and squeezed them down slightly before
reinstalling it. Next step is to replace the plug
and pins in their entirety.
Of note, when the battery is low, ie for the first
10-20 minutes of flight, there are no problems, it
charges normally and indications are rock-steady.
When the problem manifests itself, turning the
alternator OFF drops the indicated amperage to 0 and
battery volts to around 13.5-14.0 as you'd expect.
Reselecting the alternator several minutes later
shows normal charging until the current drops, then
the problem recurs.
From what I've done so far, I figure:•I don't have
any loose fittings (the only one left to check is
the Alt Field pin onthe VPX-end socket)
•The problem is 'actual', not an 'instrumentation'
•The problem is internal to the PP alternator
•The problem is not vibration-related as it is too
regular in its' cycling.
I can't see a problem doing so, but rather than
replacing the alternator, is there any reason I
can't install a separate external voltage-regulator
in addition to the internal one in the PP unit?
So...Does anyone have any ideas?
I found a nice page listing all the Wx
abbreviations, descriptions, phenomena, could types,
etc. I added the link to the

hours and three controllers later I was still up there above
the deck, listening to music, contemplating about life and
giving PIREP to a rare flyer who ventured to punch through
the thin layer. I didn't finish the silhuette the fuel was
running low. I promised my buddy to try again next year.
VAF'ers, Some may remember me from the 08/09 era. I built
and flew a -8. Great airplane by the way. In the 9 plus
years I have been away, I've helped several friends finish
up and paint their RV projects. I have purchased a 7A Tip up
kit from a friend that started it around 06, and never
finished. I have already converted it to tailwheel and now
working on the slider canopy conversion, Just wanted to
re-introduce myself and say I was back in the RV business.
Really glad to be back.

Practice in 'The System'
Yesterday I went for gas up in Sherman and
thought I'd flex the brain a bit (not saying much).
Filed IFR using FltPlan.com and tested out the
import into Garmin Pilot feature for the first time.
Seemed to work fine. IFR out of a non-towered
field into a non-towered field, and back out of a
non-towered field equal sign time on the phone.
I bet this was so much more a pain in the arse
before cell phones bluetoothing into headsets became
Got some time in the system, the ILS RWY 16L at
KAFW, got steered around some conflicts, cancelled
IFR at missed and back over to 52F for lunch.
Then home and work.
A good morning to practice perishable skills.
Getting vectored around some heavies was kinda fun.
Behind a FedEX Airbus for a bit on the approach.
Testing - Wheel pants or not?
Q: I did all my flight testing of our
RV-7A with my wheel pants off; standard practice in
Minnesota in the winter. Come spring, wheel pants
back on, and retesting WOT, I found significant
difference in max RPM and airspeed from my no-wheel
pants testing. In reviewing the new FAA Test Flight
cards, where they go into such detail as where CG
should be, and how much fuel to carry, for each
test, a question occurred to me.
Relative to Vx, Vy and best glide testing, would
they change, depending on wheel pants or no wheel
If so, I will want to retest, this time with wheel
pants on. I may even retest anyway, following the
FAA Test Flight instructions, just to confirm my
A: (Raymo) The drag
imposed by the exposed landing gear is significant
and would affect glide speed and distance. I
gained around 20 MPH after installation of mine.
Everything got better, including CHTs.

Help for a TALL pilot ...new guy chimes in.
Good afternoon. This is my first post.... I'm
very interested in the rv-14, but I have a problem.
I'm 6'6'' with a 35'' inseam. Half the people I talk
to say no problem, the other half say no way. Would
love to be able to "try one on". I'm in central
Florida. At the very least, I would like your
opinions. Thanks in advance.
I am 6'5 w/ 36" inseam and I built my RV-9 to fit
me. I have no issues. Seems like a RV-14 would be
even better height wise and mostly width wise.
Micheal, I am 6’3 and 200 lbs with a 99th percentile
sitting height. Small aircraft have always been an
issue with my head hitting the canopy. I got the
opportunity to sit in an RV7/8/10/ and 14. The 7 was
too short in either seat (head pressed into the
canopy). The 8 was good in the front seat but
impossible in the rear seat. The 10 was ok, but with
the headset on it was occasionally touching the
cieling. In the 14 I had no contact between by head
and the canopy except in low G maneuvers, but that
was likely due to the loose seatbelt. Not saying you
will be the same, but hopefully this helps.
6'4", 32 -34 inseam with an RV9a I built with almost
14 mod, rudder pedals moved forward and have plenty
of room. The RV14 will not be an issue.
inseam means you are more concern about leg room
I am 6’3”, tall in the torso. I sit on 4” of Medium
dense foam that compresses down to 2”, 3” of back
foam, Bose headset, geezer accordion sun shade above
head. All this leaves me with about 1” between
headset and shade.
I wear 31” inseam pants and thinking of bring the
pedals 1” closer. Plenty of leg
I say 6’6’ should be no issue
Hey Tall Guy,,, I’m
,,,added this bar to recline my seat (-8A) and it’s
helped a lot. Also, using a thin high density foam
seat cushion with an Air Hawk air cushion on top of
that-just right. I’m 6’3” and on the larger side.
The -8A fits great.
TALL SEATBACK OPT.
I’m am building an RV-14 and wondered
the same thing. I flew in a local RV-14A and had no
issues with leg or head room. I’m 6’-6” 36” inseam
and weigh 250#. You should have no trouble at all.
I’m 6’4” 210lbs 36” in seam, I fly a -6 with almost
a -14 mod, I fit quite well.

Installing GDL-82 In Completed RV-8 ...ArlingtonRV
I just completed the installation
of a GDL-82 in my 2001 RV-8 (I'm not the builder).
The good news, I just completed the validation
flight and have all green and got the Incentive Code
to apply for the rebate. The bad news, I started all
this on December 22nd.
The long span is all my fault and the result of a
few things, 1) even though I thought I panned ahead
to have everything on hand, I still needed to order
a few things, 2) I planned to do it over the
holidays so getting the things I forgot took longer
than usual to get, and 3) I had no idea where I
wanted to mount everything and spent a lot of time
working out logistics.
This is simply intended to show what I did. It
works, so it is a viable option, but not necessarily
the best or only option.
The first consideration that took a lot of time to
resolve was where to put the GPS antenna. I have a
Garmin GNC 250XL so there is already a GPS antenna
on the turtle deck. I considered putting the new one
next to and farther aft of the one that is there,
but to maintain the 9" minimum, 12" preferred
distance between antennas that idea became
I then considered replacing the 250XL antenna with
the GDL-82 antenna and just living without GPS on
the 250 XL (I have an Aera 660 and an iPad running
Fore Flight), but I didn't really like that idea. I
also considered replacing the 250 XL antenna with
the GDL antenna (they use the same hole pattern) and
using it to provide GPS data for both units using a
splitter. The problem there was more wires to run,
another piece to mount and another $300. I ended up
using the antenna shelf from the RV-12 (current part
number F-01201R-1) on the firewall and mounting it
there. When complete, it looked a lot like this:

Retirement at Cleaveland Tool
For 24 out of our 26 years at Cleaveland Tool, Marshall
McDowell has been pumping out tools that change the lives of
builders around the world. He is retiring this week and I
thought it would be fun to solicit comments from users of
his work. Annette and I get to hear it from customers on the
phone and at Oshkosh, but please consider passing on a
message right to him to show your appreciation of top
quality dimple dies, squeezers, edge formers. We hired
Marshall in 1994 from a jewel cutter, knowing if he could
see facets on a stone he would work well with the details we
needed. Since he has trained the half dozen people that
currently do the same (including another jeweler). Happy

Why not more Nord-Lock washers?
I've been wondering for some time why Nord-lock
type washers are not used on our birds. They have a
neat design that uses tension in the washer to
rather than friction in the locking nut to provide
the locking action. They are touted to be
particularly good in high vibration environments.
I finally came across a set in my Matco brakes; the
AN4 bolts that hold the pad opposite the plunger
have Nord-like type washers. It's a bolt into a
blind hole, so safety wire or Nord-locks are the
only way to secure them.
My question to the VAF brain trust: Why aren't these
washers used more frequently? On my IO-360, all the
bolts use the ancient star washers as "lock
washers." It sure seems they get smashed down pretty
flat after one use. Is it the price?, love of pre
Wright bro's technology, or some other reason(s)?
RV-10 Family Affair ...Rhome, TX
After 17 years of thinking about building an
airplane my RV-10 kit is on the way!
Project has come full circle from the RV to Lancair
to Glasair to Lancair to RV. Originally wanted the
RV as it is based on proven and time honored
construction, went to Lancair for the 4 passenger
capacity, to Glasair for the cost and speed, back to
Lancair for the capacity and finally to the RV for
the proven construction and 4 passenger capacity.
When my wife and I first started talking about it
she was not only supportive but excited, even after
telling her we would need to buy some tools. All she
was concerned about was being able to help with the
process. She also advised that if we were going to
turn the shop into an airplane factory we would have
to clean it up and get organized.
While waiting on the kit, we ordered the practice
kit, talked with a couple of builders and started
practicing. She says it is a lot like sewing;
pinning your patterns together and then sewing them
up, albeit with a few more steps and precision.
Riveting seems very simple and easy with an
experienced builder by your side but the rubber hits
the road when you are on your own. Sure glad we are
making as many mistakes as possible on the practice
pieces! This morning we decided to practice drilling
out rivets and after several ovaled huge holes and
finally discovered the best way for us and
successfully drilled out quite a few rivets.

I'm going to toot Jerry
Esquenazi's horn a bit. Getting your plane on the
cover of Sport Aerobatics just means you have a
beautiful airplane. Winning the Sportsman Regional
Champion position in TWO IAC regions means you know
how to fly the wings off that beautiful airplane.
Jerry took top honors in the Northeast region in
2018 with an overall average score of 82.92 percent!
He also took top honors in the Southeast region with
a mind-blowing overall score of 83.83 percent! By
the way, second place honors in the Southeast region
went to our own Randy King, flying his RV-8.
Jerry will be stepping up to the Intermediate
category in 2019 just to give me a hard time. All
you Sportsman competitors can take a breather.

So I cleaned up the flange and here is the result:
I call this a reverse layup:
Clean flat sheet of glass.

entertainment I had picked up a copy of Kit Planes

of a bright yellow RV8 on the cover and in the

convinced the better half about a year later I
ordered a RV6 empanage kit . The build started but
as usual kids work and a year out to build a bigger
garage to put it in have all taken toll.
There has never been a dead line as there are
already too many and this is a hobby, after years of
leg pulling I could put it off no more .With very
few jobs left to complete in the garage the RV6a saw
the light of day for the journey to the airfield for
final assembly and the 90% of jobs to do .

Hoping to get some good advice for solving my latest
issue. My installed main gear legs have developed
"rust freckles". Both have been installed for about
4 years (really slow build) and both have the
original powder coating as received from Vans. I
suspect with some of the wild temp and humidity
swings has caused condensation to settle on the gear
thereby making the rust freckles. So, given they are
installed, can I sand down the powder coating,
clean, prime and paint. Or should I consider
removing them and having them stripped and re-powder

RE: IAC Known Sequences for '19 ...Brian RV-4
Thanks Ron! It looks like a fun sequence. Can't
wait to try it out this weekend! I kinda like the
reverse wedge better (more fun), but I understand
that it's more difficult without inverted systems -
although I don't have any problems with mine. I just
want to keep the negative stuff to 3 seconds or less
in duration b/c I'm worried about oil starvation for
the engine. Fuel-wise, no problem.
I totally agree with Bill on the snaps. I've
recently got some dual time in a Pitts S2B and done
about half a dozen of them, but cannot seem to do a
decent one in my -4. I just can't get it to break
cleanly no matter how hard/ briskly I pull on the
stick. I'm sure it's technique, and I haven't figure
it out yet. Maybe I can get some input from you
guys. I know snaps are not in the Sportsman
sequence, but I like to learn new stuff and just
have fun (besides flying competition sequences).
Well, look at you! One contest in Primary and you
are already practicing Intermediate figures.
I'm going to keep my eye on you!
Your -4 is a different beast than my -8 so what
works for me may be different in subtle ways.
Generally speaking, a snap roll works when one wing
is stalled just when the yaw motion is introduced.
The sweet spot for my -8 is 100-110 knots upon
entry. I suspect it might be lower for the -4 and
maybe Bill McLean can chime in here. Snaps work best
at a high power setting with plenty of prop wash
over the tail so it would be best to slow slightly
below your ideal entry speed, add full power and
initiate the snap as you get to entry speed. Apply
rapid aft elevator to pitch up about 10 to 15
degrees. You should feel about 3.5 Gs in this pitch
up. (Full aft stick is NOT required.) Add rudder
just as you add back stick. Full rudder position
should be reached at the same time the Gs peak at
3.5. This is the point where one wing stalls and the
other at high alpha induces a rapid roll into the
stalled wing. As soon as this happens you should
release the back stick pressure as you don't want
both wings to stall. It's OK to add just a bit of
aileron into the snap as well. To recover, lead the
stop point and apply full opposite rudder as you jab
the control stick slightly forward of neutral. The
point where you lead the stop point will vary with
aircraft so that will come with practice.
More than any other maneuver, the snap procedure is
very dependent upon aircraft type, trim, speed and
pilot inputs. You made do a hundred before you find
the right combination. You will know when you find
it. There is no doubt when the inside wing stalls
and rapid rotation occurs. You will feel it and hear
it and the RV grin is evidence that it really

Please read if converting from Fixed pitch to Constant Speed prop
...AX-O 1/15/19 Update
Well, it has been a long
troubleshooting event. Leading down multiple rabbit
Background info: I removed the
engine from the plane to access the firewall for the
governor cut out and also to send it in to an engine
shop (name held on purpose). As the engine was
already at the shop I asked the shop to convert it
to constant speed. They said no problem.
Bad Assumption: Everything should be working, they
After I did the test with the air on the 90 degree
fitting (nose of the engine that gets the governor
line), I started researching on VAF and other sites.
That lead me down the path of the hole or no hole,
NPT plug or not.
in order to confirm the problem, I tried to prove
that saying of "insanity is doing the same thing
over and over again, but expecting different
in this case, I was not insane. The results would
differ and were not predictable. Sometimes I would
put 40 psi of air in the plug and the prop would
move. Sometimes i would cycle the prop a few times
with the engine running and it would work. Then it
would not work after a certain number of prop
cycles. Sometimes it would work if I "double pump"
the prop lever is my RMP was at 2200. Seemed like it
always failed to cycle at around 170 deg of oil
temp. All that took time to diagnose and collect.
I designed a pressure differential
tool that would work just like a cylinder
compression tool. I would put 40 psi of air in the
90 deg fitting and read the actual pressure in the
system. Sometimes the tool would real 22-24 psi and
the blades would move; and some times the 40 psi was
going straight out of the crank case vent without
any prop movement or pressure.
Talked to a local A&P and he said I should
instrument the governor to check the pressure. So I
contacted the PCU5000 folks for guidance on how much
pressure I should see at what governor rpm. They
told me that max pressure of 320 psi plus/minus 20
happens as low as 1700 governor rpms. So 1700 times
the governor ration of .866 gave me the engine rpm
required. at 1600 ish engine rpm i should have a
good check of governor pressure and not blow the
gauge to the moon. I ran the engine at 1600 rpm and
the pressure gauge read 350 psi. I called that good
as the calibration on the gauge was not checked for
accuracy prior to using. we just knew it work as
they A&P uses it to check pressure in the fuel/oil
lines he makes. Pics below of the set up.

IFR Rating RV Update ...airguy
Update on this thread...
It took a while but I finally got my ticket wet this
morning. We've had lots of IFR weather here since my
checkride, but most of it was LOW IFR and had icing
conditions, so that was a no-go. I've flown a fair
bit IFR in VMC since getting the ticket, but this
morning was the first chance to fly solo actual with
conditions fitting a minimum-experience fresh IFR
I took off from my home private strip after getting
clearance via FSS on cellphone, entered IMC about 30
seconds after takeoff, was in-and-out of the tops
enroute, and didn't see the ground again until 700'
AGL on the RNAV 25 at KMDD. Perfect conditions for a
first-solo actual flight. Now with the weather soon
turning warmer and ice becoming less of a threat I
should be able to add more actual to the logbook and
fine-tune my personal minimums.
Flying with an instructor or safety pilot under the
hood, or even solo in VMC, is completely different
than solo actual. I expected a little pucker factor
the first time I went IMC and it was there,
definitely an attention-getter. Huge fun!!

momentarily then re-booted with all frequencies and screens as they were
prior to the event. This happened once before exactly as described. Just
goes black and immediately reboots back as it was. I never could find a
reason and I am stumped still. I checked all connections carefully to be
sure. I would hate to be driving an approach to mins and have this happen
again. Anyone have a similar experience? Any suggestions?

Haven't had a lot of time to update the thread in

forward past all the other tasks that had to be done
since first hanging the wings. Going back through my
build log, here are some of the highlights...
Empennage tips took a couple of weeks to do. This is
an older kit and they were either never formed very
well to begin with, or age and heat had caused them
to distort, because they had to be cut, squeezed,
filled, and overlayed in a bunch of ways in order to
get them to fit right. Lots of work, but they turned
out nice in my opinion.

I purchased my second hand RV-7A quick build kit on
March 4, 2011 in Houston, Texas and trucked it back
to my garage shop in Maple Grove, Minnesota, with my

out where to start. I started working more regularly
after retiring in September of 2012. By June of 2015
it was time to move it to our hangar at KANE, before
we downscaled into a fifty-five and older community.

Trim tab alignment ...Girraf (7)
I'll admit that perhaps I overthought this part
of the build, but I really wanted to do this just
once. I won't bore you with the details of what I
found challenging, but here is my final result. The
hinge doesn't leave you any room for fore aft
movement of the tab if you want any hope of
preserving edge distance on those hinge attach
rivets. You basically need to drill directly down
the centerline of the hinge flange. Overall, I ended
up with exactly 3/32 gap on the outboard edge (min
distance per the plans, which I can file open
slightly), and well matched inboard edge, and the
tab itself sits about 1/32" in from the TE of the
elevator. Again, due to the hinge edge distance
issue, I don't think I had much control over how
this ended up. I'm curious if that's a passable
result or if I should have done something different
to get a perfectly matched TE. Here are some pics. I
can always order some new hinge and try again....

Thus far I haven't done anything I do not think is
reversible or fixable, but before I get to far ahead
of my self, at which point do I need to have tech
counselors take a look?
I assume before I start riveting skins on would be a
good start, but besides if I have question should I
have a tech counselor look before then?
Yep. Before closing the skin on the first component.

Ok, here we go: my minimal VFR day only panel...
light, simple, and functional
Since I bought the -6 already built, I didn't design
the panel. The holes were already there, and I've
just spent about 14 days rewiring the headsets,
installing a new 8.33KHz COM, a Garmin G5, a GT-50,
and a Garrecht AT-1 TAS.

A Pretty Neat Towbar Post From the Past ...rzbill
Due to the holiday week, I have had more "shop
time" than usual.
One of the things I have been thinking about was a
replacement of my current control lock. This was an
idea stolen from a Diamond DA20 I flew some 10 years
ago. My initial implementation was OK except the
interface to the rudder pedals was a bit light and
it popped off once, giving me a dent in the rudder
that very very windy day.
So, a few months ago, I saw and picked up a couple
of discarded aluminum crutches by the side of the

Flying into Canada without landing ...Jim RV-9A
Q: Say if a guy plans a flight from Port
Huron, MI over Canada to Rochester, NY (Niagara
Falls area) what things should he be prepared for?
Should I file a VFR flight plan or just ask for
flight following? but then what? What radio contacts
should I be prepared to make once over Canada. Does
CA charge a fee? I suppose if I have to make an
emergency landing in CA then it would get dicey
unless I just do the planning beforehand for the
contingency. Advice, comments?
A: Just file a VFR flight plan and away you
go. There won't be any charge from Nav Canada. Same
deal for us Canadians flying over the US to another
Canadian destination. When I file a VFR flight plan
from Ottawa to Halifax, I'm assigned a transponder
code and automatically get flight following. Each
controller will just hand you off to the next one. I
wind up talking to:
- Ottawa Terminal
- Montreal Center
- Boston Center
- Moncton Center
- Halifax Terminal
It is all choreographed for you, just change freqs
when told, tell them you are there, and that's it.
However, if you need to land, you better have your
passport with you and land at a facility with
Customs on site if at all possible. Also, you might
have to sit around a couple days as I think you will
have to file an eAPIS thing to get back into the US,
although I could be wrong there on the timing and
whether it is required for Americans returning to
A: I've flown that route many times going to
and from Oshkosh. As previously offered, always file
a VFR flight plan. I've never had to make an
uplanned landing in Canada, but I have heard it can
be messy. Sometimes I have used flight following.
New York or Michigan will seamlessly hand you off to
the appropriate Canadian controllers. Very easy.

My RV-7 was in an clothing catalog photo shoot ...Gash
An ad agency's models and photographers spent a
few hours today with my RV-7 doing a photo shoot for
an OGIO ad campaign. We had fun playing with the
airplane and motorcycle. When I asked if they wanted
me to "photo bomb" one of the pictures, they said
absolutely! And of course, I shared the other seat
with one of the pretty ladies.
ATC Says, “Altitude Upon Request.” Say what?
So I’ve been using VFR Flight Following more now
than any other time in my many years of flying. I
try to use it on any trip outside my local area and
it’s really been great. ATC is very accommodating
and the more I use it the less chance of my
stumbling over my words and sounding like the rookie
that I am.
So a couple of weeks ago I was on a flight from the
SF Bay Area to the Sierra foothills. During my
initial call to ATC they asked what altitude I was
requesting. I told them 5,500 feet. They told me to
fly at or below 5,000 feet and they added something
like “5,500 feet upon request.” I hadn’t heard that
So I do understand holding me at 5,000 because there
were a couple of jets flying overhead for landing at
Oakland. So, I waited several minutes until the jet
traffic seemed to subside a bit before calling back
and asking if I could to go 5,500 feet. This was
approved and off I went.
I figure basically he’s saying “yea man, chill at
this altitude for a while even though it’s not where
you want to be at. At some point hit me up later if
you still want to go higher and I’ll check and see
if it’s cool or not.” (The controller is from
California too.) I’m pretty sure this is what is
going on here. If so, I’m thinking I did the right
thing by waiting to ask for higher later. I was
perfectly fine flying at 5,000 the entire way but
that’s not a proper VFR cruising altitude.
My questions are:
1-What exactly does this phraseology mean?
2-Would it have been ok just to stay at 5,000 feet
and not request higher? I think being at the proper
VFR altitude is safer of course.

Q: I did a few searches but came up short on good
pictures. I was planning on using two padded hose
clamps but wantes to to how everyone else has done
it on a 6.
A: Almost Standard Install in 9A with
Andair Selector Switch
Here's how it turned out in mine. I used the Andair
fuel selector switch instead of the Van's, and being
that I have electric elevator trim I bend the flange
forward of the switch (where the manual trim knob
would be installed) to a 90º and tucked it into the
Hoping this mistake doesn’t equal a new HS Spar
I was trying to punch out a rivet tonight whilst
riveting my HS spar together (page 8-6). I was
unable to punch it out so slowly started to drill
further into the rivet with a #40 and continued to
punch it. Still couldn’t get it so I drilled through
the whole shaft. Whilst being careful to keep it
aligned at the top the drill bit was pushed to the
side out the bottom (see photos, first post so I
hope they work).
I’ve flicked an email off to Vans but thought I’d
throw it on here whilst I wait for their response.
Hoping to save my work. The HS-1002 part isn’t on
Vans parts list and while it may not be overly
expensive the shipping to the East Coast will be a
Also I’ve been having some issues with rivets being
hard to push in by hand due the primer. Is it an
issue to use a metal object (read hammer) to gentle
tap them in (not pounding but they are too tight to
push in with hand). Would this cause any damage to
the shaft of the rivet, if it will I guess I’ll have
to ream the holes.
Thanks for your thoughts.
Q: Those of you that use a towbar, do you travel
with it, and if so, have you done anything specific
to secure it in the baggage compartment - some type
of clamp set up? Would you mind sharing thoughts?
A: Tool Clips. I installed four 5/8ths-inch
tool clips on the floor of my forward baggage
compartment. To make it more secure I also installed
a lock pin (foreground) through one of the tow bar's
Awesome new headset! CQ1 from Card Machine Works
I’ve had the privilege of flying with a new
in-the-ear headset for a few months. It was designed
after years of frustration with the offerings from
the two established in-ear headset manufacturers.
The best part is that the CQ1 is manufactured and
marketed within the VAF family; Tanya and Scott
Card. I’m not sure what CQ stands for, but in my
mind it’s Card Quality. Card Machine Works is now a
paid advertiser on the site, headsets are now for
sale, and I feel like I can out them. I get
extremely energized by watching people identify
problems and create solutions. It's even better when
we all benefit from the results!
I’ve been flying with the CQ1 for a few months. The
noise cancelling microphone makes a huge difference
in the quality of communication and the speakers
have the quality to match. Right after Christmas I
made my first IMC approach into the LA area. it was
such a relief to have consistent clear communication
capability without having to mess with my headset.
The kids in the back seat don’t comply with the
sterile cockpit rule, so the headset mike has to do
double duty filtering out airplane noise and kids
excited about arriving at Disneyland. Communication
with SoCal approach and the tower was never a
The CQ1 is visually similar to some other offerings,
but one touch or a closer inspection reveal the
enormous differences. The differences are even more
obvious at first use. The frame is more robust and
stays where you put it. The cables are high quality
with a Kevlar core. The controls are simply amazing!
No more finding the tiny sweet spot in the volume
knob that allows both speakers to work
simultaneously! The mike is fundamental game changer
with its noise cancelling capability. It stays
EXACTLY where you put it with no spring back.
There’s no auxiliary input, that feature is easily
addressed by simple adapters and most intercoms and
audio panels have wired and / or Bluetooth inputs
My fear is that this post reads like an
advertisement. It’s not; I am however excited about
the product and what its creators have done. I like
it well enough that we have bought a second CQ1 for
my pilot wife. I own two Bose A-20s because they’re
quality, they fit the kids, and they will for years.
I own a Lightspeed Zulu II which was an expensive
failed experiment. Quality is good, but they
interfere with sunglasses and hats, and they clamp
my dainty ears; a fault they share with the Bose. I
have primarily flown with the Quiet Technologies
headset because it’s more comfortable than anything
that clamps my head. It was also fickle,
temperamental, and of mediocre quality. I have
tested all 4 headsets back-to-back and Tanya and
Scott’s CQ1 offering is the best, hands down.
I find in-the-ear headsets quieter than ANR in RVs,
especially when glasses and hats are in the mix to
break the seal with my head. I can hear the
cancelling feature in ANR headsets and find it
tiring and a bit nauseating. There was a post here
recently about that, so I'm not the only one. Ear
tips and ear plugs are a very personal thing. They
also have to be inserted correctly to work. I roll
my own using Howard Leight earplugs because they
work well for me. I think Card Machine Works have a
few other suggestions. I use the same basic plugs
for flying, motorcycling, woodworking, machine work,
and even at my day job at times. It’s on my list to
make a video describing my process. Now that I’ve
stated that publicly, maybe I’ll follow through.
Here's a link to their website. There is much more
detailed information there.

things I've not considered or will add in the future.

collective IQ and history/knowledge of this crew can find
something I should change I am sure :-)
Thanks in advance!
Front Access Panels ...bhester
If I was building today I would just mount everything so
that it could be accessed on the sub panel, it could be
accessed via removing the instrument panel. I just could not
do that when I had analog gauges. The big brain box for my
AFS engine monitor and my Lightspeed Ignition box are
mounted under the LH panel. My altitude encoder use to be
under the RH panel, no longer needed, now that I'm using the
Garmin G3X. I use clear RTV when installing them and they do
not leak. I have been back into them a number of times. I
made this mod myself, they are not the ones being sold, but
are made like them, only smaller. Feel free to go to my web
site and look at my ugly plane ;-)

Master contactor failure (maybe?)
Looking for some advice. I've got an RV-6A with a Lycoming
IO-360 and Skytec starter, 750hr TT. I bought it flying
about 350 hours ago.
Went flying a week ago, and after a fuel stop, I tried
starting back up, head a "clunk", then nothing. Tried again
and it worked... gremlins I thought...
Then I went to go flying today, and after turning the master
power on: "clunk clunk". Then nothing. My engine display,
which is always on if the master power is on, was "off". I
toggled the master switch a few more times for
troubleshooting and got a wide variety of results. In some
cases, I'd get the prop spinning like normal. Other times,
I'd turn the starter switch on and absolutely nothing would
turn on - not even any "clunks" of the master
I confirmed the battery is healthy (I keep it on a tender
and then checked the voltage independently - good). The
weather was mild.
I replaced the starter solenoid about 2 years ago after a
similar problem. This one is different because sometimes I'm
not getting any power at all... but when I get power I can
engage the starter.
So, I "think" my master contactor has failed. I only have 1
battery and 1 alternator, but the plane has 2 master
contactors in line. When I heard the "clunk"s, they were
coming from just one of them. No noise from the other at
There is no marking on my contactors, but they look kind of
like Aircraft Spruce's LAMAR SOLENOID 12 VOLT CONTINUOUS

Do master contactors fail like this? Thoughts?

Carb Issues ...Stevegrasley
Over the last few months I have been
noticing a small amount of dirty fuel/oil dripping out of
the nose gear faring onto the nose wheel pant. Nothing
really significant and I chalked it up to little leaks,
dribbles and dirt on a 5 year old O-360 that I fly behind
300+ hours every year. Nothing else to note in terms of
performance anomalies (fuel consumption, power, engine
performance in general) except that I seemed to be having to
diddle with mixture more and more in the last few months to
get nice stable performance at altitude.
Yesterday after a 1 hour flight I pulled up to the hangar
and was shutting down. Low and behold the mixture cutoff was
fully pulled but it just would not shut down. Would slow way
down and then burp and cough and rev up a little more and
keep coughing. Seemed like it was definitely not "cutting
off". Shut the dual PMAGs off and after a little dieseling
Pulled the cowl and noticed a lot of fuel sitting in the FAB.
(Wow! Where was this fuel coming from? No external leaks
anywhere around the carb.) Took off the airfilter thinking
the fuel sitting in there was the cause of the continued
running as it vaporized. Fired up without the FAB and
everything seemed OK. Did a run up and all good. , But, then
it started running rough at idle and I had to lean quite a
bit for the engine to run smooth. I am at sea level and it
was 75 degrees. Odd. Like it was way too rich for some new
reason. Tried a shut down and similar story. Shutdown the
dual PMAGs and finally got it to quit.
After shut down I noticed a fair amount of fuel dripping off
the back of the FAB mounting plate. It was not obvious to me
where it was coming from but I think it was internally
coming out of the carb...like a float was stuck down and the
residual pressure in the engine fuel pump was forcing fuel
out...but the mixture was supposedly cutoff? This must have
been what has been getting worse over time.
I bought my Lyc O-360 from Van's and it came with an Avstar
10-4164-1 carb. Compared to the carb that I had on my 1972
C172M the Avstar is built like a tank. But something is not
I have decided to replace the carb before contemplating any
flying. Really get frustrated when I am AOG. I am suspicious
of damaged floats and/or mixture valve but I am not sure.
Carbs are one thing I have never gotten deep into
understanding. Can anybody give me a more definitive answer
based on what I have written here? Up until now this carb
has 1,260+ trouble free hours on it.
RV-9A Status Report ...9GT
Fabricating a plug for a new snorkel. It will be
removable to ease the difficulty of
removing/installing the lower cowling with a three
blade prop, and it will also house a custom FAB. I
don't care much for the Van's FAB bolted to the
bottom of the fuel servo. For experimental purposes,
I am going to embed a copper tape VOR antenna in it
and see how well it works since I already have the
materials on hand. No big deal if it doesn't work
well. I will just go with my original plan of an
Archer style wing tip VOR antenna.
Another milestone happened today. My thanks to Harry
Manvel for his assistance and shared wisdom.
Insurance PIREP ...Leah (VAF
DID YOU KNOW older pilots need to take
extra precautions when comes to insurance?
Welcome to 2019!!! It’s a new year and we’re all going to be
turning another year older. Did you know that some insurance
companies will deny starting coverage for you once you reach
a certain age no matter what your health condition is? It’s
true, before you turn 75 years old, make sure you are with a
solid company. A company that won’t reduce coverage, require
an annual medical, or require you to fly “dual only” just
because you had another birthday. There are several good
companies for senior pilots, so if you are 75 years or
older, check with your agent to make sure you won’t have any
surprises come your next renewal. Age is just a number. You
can still fly insured well into your 80’s as long as you

Saturday morning before drywall duty I had the pleasure
of giving new friend George his first ride in a small plane.
He works in law enforcement. George and Cynde are 'an
item' as the kids say, and we've known Cynde pretty much our
whole lives. Great guy! Cynde and George drove
up, and I think Cynde was planning on hanging out on the
couch. Randy walked up and said he wanted to go fly
too. New plan. "You have a hat I can wear?"
It was 00000kt and CAVU, so of course we're doing some
formation if the passengers don't object. Gentle turns
and nothing too steep for our guests, then it was up to KGLE
for gas. It seemed everyone with an airplane was
flying Saturday. I know a big group went to KSEP for
BBQ (I bowed out because I needed to be home repairing the
closet by midday). Anywho, back to the story, gas
bought and back in the air. Randy and Cynde went
direct back 52F while George and I flew over to his neck of
the woods so he could see his house. On the way we saw
a B-52, guessing out of KGYI or such). It turned away
and we got a nice show of exhaust. While on the ground
GLE I texted lifelong friend Billy T to see if he was home
(lives near George). Yes. "Go in your backyard
in 14 minutes." OK. Thankfully he didn't moon me
(it's in line with his character). Maybe his wife and
son standing next to him were an influence. Waves
Let George fly for about 15 minutes and then back on the
ground 52F, handshakes, laughs and a sense of
accomplishment. Got to treat a law enforcement officer
to some aviating fun, got to have some laughs with a family
friend, got to share airspace with a B-52 defending my
freedoms, and lucked into a greaser landing (told him they
were all like that). Later I got the 'George wants to
know how much it costs to learn to fly' text from Cynde <g>.
And so it begins...;^)
The rest of Saturday was drywall and work.
Sunday 0730 Mass, more drywall and more work. A nice,
Hope you had the same and that you have a nice Monday.
Here's the rest of the RV news from the weekend...
I have 125 hours on my RV7A with an Aero Sport 0-360 ECI
engine. The prop is a Sensenich metal prop purchased through
Vans. During take off and level flight I have a vibration.
When descending it is not near as noticeable. I had the prop
dynamically balanced. It seams to be better when lean of
peak. Leak down and regular compression testing show good.
Ignition is a Light Speed II and one mag. Timing is set
correct. Carb was just overhauled. Any ideas or suggestions?

I know I probably post too many sunset
pics, but I snapped this on a quick flight tonight and

How bad is it? (back riveting oops)
Well, I did it. The thing I said I
wouldn't do. I riveted off the edge of my back rivet plate
and damaged my rudder skin. SEE PHOTOS HERE.
Will be putting a call into Vans, but hoping someone here
can talk me off the cliff. Is this a, "Buy a new skin don't
even think about continuing," OR "A little paint filler
after completion will take care of that?"
Few positives: 1) It was barely off the plate, so wasn't
able to push down to workbench and punch through, 2) I
caught it on about the 3rd hit of the rivet gun. I went
ahead and dimpled the hole again, and that looks fine along
with the stiffener, but wondering about the dent/crease on
the outside of the skin. Thoughts?
RV-14A Status Report ...kbalch
Fuselage join accomplished this morning. A
complete non-event, as everything clecoed right together as

early -8 and the difference is night and day. I love it!
Finally Pulled the Trigger!
Might as well introduce myself... I (we) finally pulled the
trigger today after lurking for perhaps a record setting 12
years! I surprised myself and ordered an RV14 instead of the

in my garage.

RV-14 Electrical Diagram ...mulde35d
With all the discussion on lighting and
electrical noise I thought I would post the primary power
and G3X pinout diagram that I created over the course of
about 6 weeks of sitting in hotel rooms bored out of my
mind. This is still under revision as I actually build it,
but while the pictures are only JPEG I would be happy to
email the full visio product to anyone who is interested (PM
me with your email address). I created this from scratch
while referencing an electrical drawing that was produced by
a professional company to give me some ideas on how to lay
things out in a clear manner. Hence why it may look like a
paid for product, but is purely my creation. The wire
numbering scheme is also original and has a decoding method
to the madness that should help me identify wires quickly in
the aircraft should I find problems once in flight.
I am also open to any input from any electrical guru's in
the house as most of this was self learning from the
baseline installation documents with a couple calls to
Garmin for some detailed pinout instructions. Have fun on
the eye chart if you so desire.

Somewhat of a big day today. After finishing the

RV-Lancair Brotherhood Day...snopercod
The weather was perfect and we had a great
turnout today at GMU - seven people! Besides the
regulars (Darwin couldn't make it), Keith from
Greenville showed up in his RV-12, and Doug and wife
Susan from Gainsville, GA flew in in his RV-12,
making three RV-12s! Mark Cigal in his RV-8 brought
his Cirrus instructor friend Chuck from Denver.
Lunch was good as usual and it was a pleasure to
meet the new folks. I hope they'll come join us
again the next time we do this. In no particular

Master contactor failure (maybe?)
Looking for some advice. I've got an RV-6A with a
Lycoming IO-360 and Skytec starter, 750hr TT. I
bought it flying about 350 hours ago.
Went flying a week ago, and after a fuel stop, I
tried starting back up, head a "clunk", then
nothing. Tried again and it worked... gremlins I
Then I went to go flying today, and after turning
the master power on: "clunk clunk". Then nothing. My
engine display, which is always on if the master
power is on, was "off". I toggled the master switch
a few more times for troubleshooting and got a wide
variety of results. In some cases, I'd get the prop
spinning like normal. Other times, I'd turn the
starter switch on and absolutely nothing would turn
on - not even any "clunks" of the master

Exit pressure must match local exterior flow at exit
...Steve Smith thoughts
The fundamental rule of subsonic exit flow is that
the internal flow pressure at the exit must match
the external flow pressure at the exit.
When you open a cowl flap or have a diverging exit
angle, you are creating an area of lower pressure in
the external flow, which yes indeed helps extract
more flow through the internal flow path, because
you are exiting into lower pressure. The penalty for
this is the increase in frontal area needed to
create the accelerated external flow, and the
likelihood that exiting internal flow may be at a
lower velocity than the external flow.
When you have an exit in an area where the external
geometry is tapering or sloping back towards smaller
cross sections as you go downstream, the other flow
is slowing down, pressure increasing, and you are
exhausting into an area of elevated pressure
compared to the free stream. The internal flow at
the exit is therefore at a higher pressure, lower
velocity than it could have been. In small doses,
this region of decelerating flow, with rising
pressure, can be good - the pressure recovery on the
aft-facing slope provides some thrust. But if the
pressure gradient is too adverse (pressure rising
too fast) the boundary layer will separate and you
will have a separated flow region trapped in the
area where the body is getting smaller, causing
pressure drag - which is a way of saying that you
are not getting the pressure recovery that you would
have gotten had the flow stayed attached.
Tuft Testing and Systems ...DanH (same thread)
Larry, first suggestion is to think in terms of
building a system. Whatever individual modifications
you might make should be considered in a system
context. Bandaids only go so far, and real bolt-on
speed is rare.
Next, remember the little things. I'm going to take
one subject as an example, that 4-pipe exhaust.
You're thinking about cutting off the downturns, but
in the context of how to reduce cooling drag, the
best bet would be to stack it under a workbench

Inspiration from 'Ron's Cart' ...TASEsq
I took great inspiration from Ron’s cart below,
but not being able to find a cheap cart that wasn’t

mine. The drawers are very handy (they are 10mm
ply), for stuff needed often but not every second.
The drill bit holder and die holders are the best
things ever - never have to search for a bit, and
I’ve since removed some I don’t use and added
reamers for an3 and 4 bolts. The air tools hang on a
bit of PVC pipe with notches cut. I also now have a
sandpaper holder on the side, and found 5lt olive
oil cans are the best for clecos. Very handy having
all the hardware boxes wherever I’m working. Thanks
for the inspiration!

Video on RV-12iS Drop In Lines ...Aircraft Specialty
[ed. I enjoyed this
video immencely! If you have a 19 minute hole

The rv12is provided a great opportunity to fully
utilize CNC tube bending technology to provide drop
in lines for the 12iS aircraft that the OP of this
message utilized in his aircraft.
Here is a video that shows the design process,
fabrication, as well as tube final dimension
The 10:22 mark is where the actual tube bending
begins. The rest of the video shows how the entire
process is done from start to finish.
As always, we couldn't have done this without the
help of some great beta testers. The RV/
Experimental community is comprised of some great
people, and we really enjoy working with you to
refine and improve the build experience.
HS spar scratches RV 9 ...toddramsey
"...finished match drilling my ribs to the spars
on my horizontal stabilizer. When I disassembled and
removed the blue plastic, I found these shallow
scratches. I believe they came from the brake used
in bending the spars in the manufacturing process.
The blue plastic was also cut along these scratches.
I used mineral spirits to clean the scratches to
remove the plastic residue and the photos show what
remains. These scratches are very shallow but I can
feel them with my fingernail."

Potentially catastrophic mistake: Aft canopy deck position along the
Happy new year everyone. Wish I could
share in the happiness, but I just found what's
possibly a catastrophic mistake I made on the RV,
and wanted to share it. Obviously this is going to
involve a long discussion with Van's, but I thought
I'd start a discussion here to potentially prepare
myself for the extremely bad news I have coming.
Long story short, it looks like I built the whole
forward and mid fuselage around incorrectly bent and
I'm at the point in the build where I'm
disassembling the forward fuselage to prep the
surfaces, dimple, and countersink them for riveting.
While countersinking the longerons, something just
didn't look right. The top holes I had drilled for
the aft canopy deck were way too far aft. So I
clecoed the longeron back to the mid-fuselage, and
pulled out the F-721B aft canopy deck pieces. Lo and
behold, the holes are indeed way too far back:

Getting Back to Building! ...llavalle
So some of the older folks here might remember
me. I was building a -9A back in what.. humm
2008-2009. Had a webcam link in my signature which
was awesome in 2008.
Went to 'Osh in 2009 and met some of the folks
here! At the Van's dinner, our host here, DR,
recognized me by saying "hey, you're that French
Canadian guy from Québec, right?"
So anyway, after 265hours and 3642 rivets (yup,
counted them), life had other plans for me and I
paused the building of the -9A. ~2 years later, was
offered a very good price on it so I decided to sell
it. Emp was complete and inspected by MD-RA
(specific to Canada stuff). One wing was mostly
complete, the other one I was working on.
Unbelievable! ...Don Patrick

Flight Data Recorders: Foreflight logger, Arduino, Raspberry Pi
So last week I decided to fly some simple tests to
determine how useful the Foreflight Track Logger is
in capturing data for Flight Tests.
So I flew a simple plan which consisted of taking
off, flying wind speed and direction circles at 5000
feet and then again at 8000 feet, then doing some
simple aerobatics to see if the Track Logger could
also be used to tell me how I'm doing with the acro.
The results were interesting. I downloaded the
CSV file from Foreflight and wrote some Python to
capture the data and plot it out in 3D.
The short answer is - the Foreflight Track Logger
might be useful for Phase 1 flight test of climb,
airspeed calibration,best glide, Vx Vy determination
Doesn't seem to be useful in showing a round loop.
This is the 3D plot of the full flight. The roll,

Happy New Year - And (Maybe) Hat Sighting ...tcard
Happy New Year to all of our flying friends! The
Year 2018 ended with a flight, so it seemed
necessary for 2019 to start with a flight. There
wasn't any of the requisite noise from our airpark
community, so we decided to fix that even though the
weather was, well, not great. Clearly our fellow
pilots needed a ceiling report. The consensus in our
cockpit was low and "variable".

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...
all day. Line repair made. Fans drying things out.
Sheetrock plan being formulated. All about
back to normal, and we’re only out about $20 so far
in plumbing supplies. Looks like a clothes
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

flow is not perfect but better than the first

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.

I know there are a number of ways of configuring it

preferred setups are for IFR work and how I do it.

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

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....

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.

Now the plane is loaded again to its aerobatic

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

Question: strange result with a long pop rivet
I need some advise here:
The pop rivet turned to be absolutely hollow , the
ball and the pin who supposed to hold it from inside
are completely torn out by the rivet gun (seems like
uncontrolable process with this kind of rivets). We
aware to the fact that this os defenitely reduces
the rivet strenght , but how bad is it? May this be
acceptable at this specific place ? Moreover , there
in an open hole in that place , how bad is that?
The location it happened is the plastic that leads
the cable for the rudder control. Here some

What floored me was the email he sent today.
"This thing is the closest to a self-building
airplane I’ve ever seen. I’ve been working on it for
a touch over a month, the engine is installed, and I

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.

on his aircraft in his hangar at 8A7. I know Robert
well known in the Houston Texas area, and he had
relocated here to NC in retirement a few years ago.
He completed his RV8A about 2 years ago, and has
been one of those guys that came out to the airport
almost every day, rain or shine to fly or work on
his RV. He was a man with driven passion for this
great hobby and the friendships that go along with
it...Robert will be missed by our 8A7 community, and
those who knew him. Arrangements have not been
disclosed at this time... Praying for his family.

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.
Update on Wheel Pant Fitting ...Bill Boyd RV-10
back to the shop last night and tried on a pant
after the reinforcing plies of fiberglass around the
preliminary mounting holes had cured 24 hours.
Rechecked Plumb Bob and all his buddies. I was
astonished to see that only one of the six holes in
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.

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!

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." -

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.

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.

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.

This year featured a NOTAM 20+ pages long and the

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
2nd airplane. Sounds like a good idea. Hoping to see if it's
1% or 5%, or more....
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
example...as would a C170/C180.

be a yes. Same in reverse....flying a bush plane and

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

it doesn't support the remote button. The 430W will
still provide guidance and let you couple to the

Help build an Eagle's Nest RV-12 ...brad_walton

volunteers to help with construction:
To The RV Builders in the Houston Area,

and flight instructor in the Houston area, and the
Construction Foreman with the Alief Independent
Alief ISD would like to partner with Eagle’s Nest
Foundation and have some of our students build a
Vans RV-12 at one of our high schools. One of the
requirements of the Foundation is that we have
homebuilders with RV experienced overseeing and
mentoring the students as they work on this project.
The STEM teacher that is leading the project is
named Steward Bailey and he is a certified A & P
mechanic, and will be there throughout the
construction. The aircraft will be assembled at the
Elsik High School, located near the intersection of
Dairy-Ashford Drive and the West Park Tollway, in
southwest Houston. Eagle’s Nest will supply the
materials, and all the tools will be provided, but
they would like a minimum of four (4) experienced RV
builders to be involved to mentors to the students.
With enough volunteers, it may mean a commitment of
around 1-2 hours per person, every couple of weeks,
throughout the school year.
Alief is predominately a low income school district,
and most of the kids would never have the
opportunity to experience aviation if not for
projects like this. We at Alief think that this is
not just an opportunity for some young people to
build an airplane, but to also learn meaningful
academic subjects, as well as lessons in personal
enrichment. If you ever wanted to share your skills
and expand the great community that we call
“Aviation”, this is your chance. What we need is
your time and talent, as well as your hands and your

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

One of the cylinders is still leaking fluid. I think

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

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.
Engine is next!

Since I just couldn’t cut a tapered hole in the landing gear

under the top of the F-308 bulkhead.

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>.

Reality Check? Value of 1993 RV-6 ...punkin
I've got an itch to do something different, which
probably means I'll regret it later...I LOVE my
RV-6! Some of you have followed as I progressed
through larger tires, ground adjustable prop, and
then engine upgrade in my attempts to turn my -6
into a super cub.
It's been fun, and it's a decent trade off to have a
145mph cruiser that can land on some rough fields,
but I'll never have the comfort level of doing the
real slow and low in this airplane.
I'm considering selling, and just want a reality
check. I know I'll never get what I paid + what I
put into it (about the same as I paid again) over
the last couple of years.
But, since this is a forum that never lacks strong
opinions...if I put it up for sale here or one of
the big online sites...what should I expect to ask
and receive? I'll probably put the stock tires and
wheel pants back on because most people don't buy an
RV to go slow...

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."

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'

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!

Status Update ...Bill Boyd RV-10
Haven't updated progress in awhile in my own
thread so here goes.
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.
Reminder to self: moments like this are why we carry
After much pondering I decided there was no need
to make a sawhorse just for this job. The EAA
workbenches I have on hand should be tall enough at
34" and will certainly hold the weight. Tail resting
on one bench, engine mount double-strapped to engine
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
project in Columbus, Ohio three years ago.

Big step! 34" bench height seems to give plenty of
ground clearance for wheel installation. I'll know
for sure tonight.

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

New RV-8 Project Purchase
My wife and I just purchased a RV-8 kit that is
mostly complete. The builder started back in 2000,
so it is an older kit. We have never built a RV
before and we sold our Bonanza to fund our project.
See we are not new to aviation but brand new to the
I know there are some SB's I should comply with but
any other tips of items to do on an older airframe.
We live in Maine so good heat will be a must. Where
do people get the heated seats?
We want to do the G3X panel with the Garmin
Autopilot. Will we need to open up the wings or tail
to install the servos?
So far we know it needs paint, a panel, a propeller,
and an interior. It should be delivered in early
December. We are very excited!!

kit announcement so he would be the best person to

be offered in only one color. The same metallic
medium grey that was used on the prototype (N912VA)
The kit will include all 3 panel sections and the

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."

Pink Cowl Seam Fit ...snoopyflys
Hi Fiberglass Gurus;
Now the cooler weather is starting to move back into my
area, I started to turn my attention to reading, staring and
mulling over the cowl fitting on my RV-7A. In the photos
below, I think I have the top and bottom cowl somewhat in
the position to clear my Whirlwind GA prop spinner (3/16")
and close to finished along the firewall. However, the seam
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?

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.

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.

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.

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 I set the aileron position using a taut
string with a loop tied in one end clecoed into the

the other end taped securely to the trailing edge

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

“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."

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.

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
(airworthiness certificate) for E-LSA aircraft.
You could receive compensation as a flight
instructor while giving training though.
The NPRM you mentioned is related to compensation
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
period, so that they were legal aircraft under the

It's possible with a mushroom set, but it's tough

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.

a bit on whether the content you’re looking at here maybe
thirty times a month is worth $2.08. Again, I
apologize for the commercial - I’m pretty certain I dislike
talking about this more than you dislike reading it. But, I
need to speak up a bit now, because the year isn’t looking
so great if things stay the way they are. Please give
donating some thought...and thank you if you have already.

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

Great place to put stuff if you aren't going to have a glove

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.

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?
Miles: Canopy Glued ...dwranda
Finally got the canopy glued on with sikaflex.
Definitely not as neat of a job as some guys build
sites I follow. Now I can take it into my basement
and do more detail work on it so it looks better.
Then I will fiberglass the front edge. I will be
listing the canopy clamps if anyone wants them. I
got them from Av8torTom and will pass them along
free to whoever wants to use them next.
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....

Do I want Steps? (RV-14 Taildragger) ...Mark Elliot (Minneaopolis,
Need to make a decision.......help? Do I need /
want steps on a -14 taildragger? I know it's my
choice, but for those of you who fly the -14
Taildragger what do you prefer?
if its a 14A doesn't matter your opinion - sorry
A: At very least the steps would be an
indicator to onlookers .. maybe avoid somebody
stepping on a flap and causing some grief
A: ...But I'm 36 years old and 6'2". Check
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.
5) Bob Axsom made his removeable, and speed testing
showed less than 1mph difference with and without.
As a result, I am building with them. HTH,

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.

A: These are most likely

color chart from them for the stock colors they
have. Very sex paint. Good chance the Cirrus colors
are custom. You can take a class from Sherwin
Williams were they shoot this paint.

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.

Enjoying this site? I hope so. Please excuse
this 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 this year
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.
One of the reasons I’m getting my commercial rating is so I can
hopefully fly the occasional side job for a little extra family
income. Having things all hang out in a small family business
isn’t exactly the smoothest ride, if you were wondering ;^).
So good morning, enjoy Monday’s edition, and while doing so ponder
a bit on whether the content you’re looking at here maybe thirty
times a month is worth $2.08. Again, I apologize for the
commercial - I’m pretty certain I dislike talking about this
more than you dislike reading it. But, I need to speak up a bit
now, because the year isn’t looking so great if things stay the
way they are. Please give donating some thought...and thank you
if you have already. Thank you very much!
This small business owner is trying his hardest to bring the RV
builders and RV pilots of planet Earth a quality product.
I'd like to keep doing it.
Thanks for reading this and have a great week,
(and Susie, Audrey and Tate...and Moondog).
How and why I
do the donations the way I do.

join up and support the site.
I want to dedicate my first post to Steve Hurlburt

Steve is a member of this site and has built several
RVs. He happened to live in the same city where the

Steve through this site, he agreed to perform a
pre-buy inspection on my behalf, including a test
flight. He then provided me with in-depth written
reports on both. And he did this without any
expectation of compensation! I was truly impressed
with his incredible support. His feedback allowed me

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.

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

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 -

together or if I need to redo this line.

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

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
