Check the vent hole. If it is plugged, that was what caused most of my
problems. You can thin veriprime with acetone. thinned out primer sprays a
lot easier. you are looking for a very thin coat anyway.

Yes, I initially flew my RV-6A without the wood stiffeners and disliked the
amount of bouncing and swaying. I tried the nose gear as well without the
stiffeners and found that it did shimmy under certain conditions. I then
applied the stiffeners and liked the ride much better. Not trying to
convince anybody to install stiffeners, this is just my experience with
them.

I check my original nose gear with dye penetration and found no cracks, but
changed over to the beefer nose gear that van offer as replacement just to
be on safe side. I flew the new one initially without the stiffener and
noticed what appeared to be a tendency for the nose gear to tuck under (at
least that is what it felt like - I am certain it was not really tucking
under), so added the stiffener and that went away. No need to add wood if
your gear is giving you what you want. I would not suggest that anyone take
my advice over Van's regarding wood stiffeners, it is just that I have tried
it both ways and found I prefer the gear with wood stiffeners.

Yes, a second or two more and there would not have been adequate runway
remaining. Does get your old heart a pounding {:>). Whether the gear would
have hopped without the wood stiffeners is conjecture on my part, but having
seem similar response to hard braking with wheels on spring gears, I do
believe that the stiffeners minimized that tendency. But hopefully, most
folks will not face that situtation to find out.

You use the mixture control to moderate power. In the 70's there was an
article in an aviation magazine about an STC for a Piper that allowed full
flight envelope power control with wide-open throttle and power moderation
with mixture. In an emergency you will disregard the roughness when well
lean of peak. The engine is getting its cooling from excess air rather than
fuel.

Thanks for the clarification, Cy. The ensuing backfire could also start a
fire. As a matter of safety, I'd feel more comfortable if list members
would leave suggestions on emergency procedures to those that are qualified
to answer them. I respect the right of any member to comment on any topic
but I feel this is a critical area with respect to safety. Some of the
comments (Lyc's can't run continuously at 100% power, use mag switch to
moderate power) could get a pilot into trouble. Please don't take offense
gentlemen -- valuable RVs and even more valuable lives are potentially at
stake here.
Off my soapbox -- and my apologies for the rather direct wording.

In discussions I've had with folks regarding aerobatics in normally
aspirated RV's and negative G's, they mention that if you go negative
long enough for the engine to quit for lack of fuel, then you just get
G's back on it and the engine will "re-start", as in start running
again, in which case I assume the prop is windmilling. Full throttle?
Dunno.
I quoted the "re-start" because I think that term is confusing this
discussion.
I also learned from the information to use mixture vice mags if I ever
get in the situation that started this thread...
Spring load the throttle full open and if the cable malfunctions, the
mixture becomes the throttle.

The only reason I can think of not to rivet them on until needed is that
unless the holes and location of the bracket are predrilled (by the factory)
then you really have no idea where the final location of the bracket should
be. It may ve close enough, or then again it might not. My rule of thumb when
building my non prepunched 6A was to not drill or rivet anything until I
absolutly had to.

Our normally aspirated, direct drive Lycomings (O-320 and O-360) are

exceptions please let me know.
This is discussed briefly on Lycoming's very informative web site. Also

The C-85 in my old Aeronca Champ would start just fine at full throttle. A
little used hot-start procedure only used when there was a qualified
hand-propper on the front and a qualified pilot in the seat. Many a pilot
have found out that without the aforementioned precautions, a plane will
start up, leap forward, and chew up other airplanes or even take to the air,
not caring that there wasn't a qualified pilot at the controls or any pilot
for that matter.

I find this thread disturbing. If you build the a/c to
proper specs and then maintain the a/c in a reasonably
timely manner i.e. performing 25, 50, 75, and 100 hour
inspections also the annual you should not have a
problem with sticking or broken throttle cables or for
that matter mixture cables cracked weldments etc. We
are building an airplane to fly in and I believe that
safety is paramount. The aformentioned problem was on
a spam can and probably in all likelyhood maintained
by a mechanic that was not paid well because he
obviously did not pay attention to detail. Guys just
build the airplane to spec's and maintain those specs
and since most all of us that are building will have
the repairmans certificate on that airplane, maintain
that airplane as if your life depended on it because
someday it just might. To the other guys who do not
have the repairmans certificate I would suggest
getting an A&P who is familiar with the RV series a/c.
Do not use anyone who is not for this reason. An A&P
who is "type specific" will know the intricacies of
the a/c and know what to look for while performing
your annual. Sure you may get an A&P who is thourough
but in the back of your mind do you want a job done by
a guy who is not really familiar with your a/c? that
is for you to decide. I just hate to see needless
accidents due to negligence or pure stupidity.

Not if you can tell me how you mounted the throttle/mixture brackets.
I know it has been done, but sometimes in the RV building process I wonder
to myself, if I am the first person to ever do some of these things. I have
yet
to find anyone who can explain to me how to mount the throttle/mixture
brackets for a Bendix Servo on an 0-360 A1A engine. I have talked to
Lycoming and they tell me that this is an airframe problem, I talked to
Van's and they told me get a carb and their bracket for the carb. I talked
to Bendix and they told me Huh!!?!
If you know how, please don't keep it a secret.

Hi Dwain and all,
It's nice that you met Bob, and that you think he's a nice guy. But like
other comments on this thread, it's off the subject.
Bob is retired from TRW. After spending his carrer designing antenna's for
TRW. Bob has documented REAL radiation patterns of antenna's on also any
shape imaginable.
If Bob says that the best location for a COM antenna is on top of the
vertical stabilizer, it's because he has PLOTTED that radiation pattern, and
the radiation pattern for every other imaginable location of an antenna on an
aircraft. (Bob may have started with a textbook, but it went past it long
ago.)
If Bob Archer's wingtip COM antenna works as well as a standard belly mounted
COM, why put the COM antenna on the belly?
The question is mine; The choice is yours.
Bob will still tell you that the best COM antenna location is on the top of
vertical stabilizer.
BTW, I've know Bob for about 20 years, and he is a nice guy.
Just my opinion.

When doing Immelman turns in a Citabria (no inverted fuel), the throttle
is wide open and at the top the engine stumbles a lot (I don't know if I
would call it quit or not), but it goes back to full power before
completing the roll at the top.

In discussions I've had with folks regarding aerobatics in normally
aspirated RV's and negative G's, they mention that if you go negative
long enough for the engine to quit for lack of fuel, then you just get
G's back on it and the engine will "re-start", as in start running
again, in which case I assume the prop is windmilling. Full throttle?
Dunno.
I quoted the "re-start" because I think that term is confusing this
discussion.
I also learned from the information to use mixture vice mags if I ever
get in the situation that started this thread...
Spring load the throttle full open and if the cable malfunctions, the
mixture becomes the throttle.

Why? The thoughtful exchange of ideas (even bad ones) help to stimulate thinking.
Welcome to one of the major drawbacks of the information age......too much

If anyone on the List is making life or death decisions based solely upon the
information posted, you'd better reconsider.

Well, if that logic held water then no major airliner would fall out of the
sky due to a mechanical problem because they are the most inspected aircraft
on earth!! And the people doing the inspections are probably better at it than
I am. Many of the responders to this thread were discussing the prudent practice
of spring loading the throttle to the open position IN THE EVENT of a break.
In addition, several posters on the List have had these cables break. Your
assumption that they broke because they failed to perform an adequate inspection
is flawed at best.

And your substantiated proof is what???? You are obviously drawing a conclusion
based upon circumstances not contained in the NTSB report. At least, I couldn't

>...because he obviously did not pay attention to detail.
I would say that he obviously made an error. I don't know, and neither do you,
that he did not pay attention to detail. I know that I've made my share of
boneheaded mistakes. I always pay attention to detail, I just make mistakes
sometime.
>Guys just build the airplane to spec's and maintain those specs
Sure, I agree, but what does that have to do with mechanical failure? Building
and maintaining to specs will not prevent mechanical failures from occurring.
That's why we have redundant systems, checklists, etc. And that's why we practice
emergency procedures and maneuvers.
You are entitled to your opinions Glenn, as we all are. But I think this thread
has wandered just a little off course. I consider it prudent to back up your
throttle and mixture connections with a 5 cent spring so that in the unlikely
event of a failure, you have an opportunity to prevent a small failure (cable
broke) from turning into a larger failure (off airport landing). The subsequent
questions on how one controls speed with a broken throttle cable is a good one,
in my opinion.

Subject: | IO-360 Throttle and mixture Bracket |
Bob,
This is not RV-specific, but one approach. I owned a Citabria with an IO-320
and Bendix injector. The throttle cable (swivel-end style) was attached to a
bracket, with about a 6 inch arm, welded to the lower left engine mount
tube. There was probably 10-12 inches from the bracket to the servo arm. The
mixture was just a bowden cable attached to the lower right mount tube and
an adel clamp on the airbox. See if you can find a Super Decathalon and see
their mounting for an IO-360.

While I agree with the thrust of your comments, I would have to say
that anything made by man can, and eventually will, fail.
Personally, I've learned from this thread not to emulate techniques
used on rotary-engined aircraft nearly 100 years ago, as I probably
would have tried to do if my rented aircraft went to and stuck at full
throttle a week ago. Neither my basic instructor, or numerous BFR
check rides since, ever covered that eventuality.
I bristled a little today at comments made implying that if I'm not a
Super-CFI or career piston pilot I shouldn't be adding my two-cents
worth, lest someone else use them to their detriment - but many of
these threads usually start with a question or ignorant comment and
through the combined experience of the participants the truth and
best-practices generally shine through at the end.
Which is why we're here.

I beg to differ with your statement that Lycs can "only run a few
minutes at full power". When I'm practicing my far off in the future
Vegas pylon turns, running my "low altitude fast route or just smoking
along, I can run max 2800 rpm for quite a long period of time without
any signs of excessive EGT/CHT/oil temp or pressure, etc. In fact, I
think I can hear my engine singing along with me on the ride, tho it is
in better tune.

The only reason I can think of not to rivet them on until needed is that
unless the holes and location of the bracket are predrilled (by the factory)
then you really have no idea where the final location of the bracket should
be. It may ve close enough, or then again it might not. My rule of thumb
when
building my non prepunched 6A was to not drill or rivet anything until I
absolutly had to.

I mounted mine whilst the wing was in the jig.
I installed the brackets first, after the top wing skins, this way I
could have the ailerons hanging whilst testing out the pushrod assembly
and making bits and pieces.
Don't forget, Van's also tells you that you can rivet the bottom skins
on after it is out of the jig, just to be carefull moving the wing out
off the jig.
I thought riveting the bottom skins on in the jig would make more sence
with the wings in the jig, unmoved. This meant riveting the brackets on
inthe jig too
I believe Ole George did it in the jig on the video too.
I defenitely would do it again, all in the jig.

Listers,
As Gert mentioned, the conversion isn't hard. Been there, done that. Essentially,
you need to drill out 14 3/16" rivets in the F-804A. These holes get opened up
to
1/4" for the bolts which will hold the landing gear weldments on. I ordered an
8A
wing kit but received an 8 center section. I spent 2 hours carefully marking and
drilling out the necessary rivets. My weldments fit perfectly. Be aware that your
rudder cable holes will need to be relocated for the 8A. See revision 7 of DWG

for details.

The aft bulkheads have added parts for the tail wheel..you would have to
take the side skins off the rear of the airplane and put in that supporting
structure. Then you would have some cowl work to do to allow for the
closure of the nose gear hole, as well as the openings for the new gears..no
small job on a flying RV..especially if it is painted...ouch..don't even
want to think about that!

Gert: Your answer to the aileron bracket was an excellent procedure. I
have been down this avenue with two Rv's. The thing that is difficult is
the vertical positioning is critical to make the airfoil conform to the
wing. As you will notice from previous builders aileron and flap alignment
is easy to do in the jig. Also you notice the quickbuilt has all the wing
assembled but the outboard top skin. The Ortmdorf method works, I have had
to replace brackets that were not aligned properly, not fun. I think all
Rv-6 builders will tell you to be extra careful in the alignment as it will
bite you later when you install flaps and wing tips for a perfect alignment
of the wing. If you don't believe me look at every RV wing alignment at
the next fly inn. Sorry for the long post, but I feel very strong about
procedure. My two cents only.

I would add to this statement that those that do not
have their repairman's certificate should still get
familiar with their RVs. Even without the repairman
certificate they can do through inspections and any
maintenance that is needed to maintain their RV in safe
flying condition. The only thing an A&P is needed for
is to sign off the annual condition inspection.

One of the best chemicals to use for handy cleaning is aerosol cans of brake

designed to absorb brake fluid and petroleum products, evaporate and leave no

Dear fellow RV-List'ers:
I had been trying to locate a supplier for some small latches made by
Hartwell. They are plastic, you push on a plunger, that expands a grommet,
and that holds your panel closed. They are small, lightweight, and have
great holding power. The only problem was I couldn't find them anywhere. I
contacted Aircraft Spruce and good as their customer service is, they really
didn't want to bother with such a small order.
I then contacted Wicks and asked for help. Deeann Vogel of Wicks has worked
for two months trying to find a suitable supplier. She took great pains to
make sure I had the correct part numbers and was going to get exactly the
latches I wanted. You don't find that kind of customer support too often.
When I do see examples of stellar customer support I like to spread the
word. From now on, I'm going to try to do as much of my purchasing as I can
from Wicks.

Ok, I've had enough.
We all know adding the spring won't hurt. My thought, just do it. If the
cable breaks you will notice it on pattern entry when pulling back the
throttle, NOT just before the flare. I bought my RV so I don't know how it
was built, if the spring is on the throttle, but I'm going to look.
The backfire thing sounds a bit like a old wives tale but I'm not about to
tempt fate. Sooo . . . .
I went out flying this morning. Up to 4000 ft. (<2 minutes) Firewalled my
throttle and flew a normal simulated pattern with the mixture. PIECE OF
CAKE. CHT and EGT actually went down. Which makes sense. Bring the
mixture back and the engine slows down, a little rough, but not bad. I even
pulled to idle cut off and back in and it ran perfectly.
Bottom line: If I had this spring on my plane and the cable broke It would
not eve cause me to break a sweat. Not because I'm a great pilot, but
because I've tried it at altitude and it is very very benign.
So before hypothesizing anymore, go fly it.

Bruce,
In my RV-8A with an IO-360 I have the flow meter mounted almost exactly 4
inches downstream from the servo with a 90 degree elbow coming out of it
then the line going directly up to the flow divider. It is not the optimum
5 inches that they suggest but it works prefectly. After 25 hours of flying
every fillup has been within 1/10 of a gallon of what the VM1000 says has
been burned. I made a small strap of aluminum bolted to the mounting hole in
the flowmeter and the other end to the engine case oil sump bolts to give a
little support to the small rigid 4 inch line between the flowmeter and the
servo.
Hope this helps.

It _is_ a great idea.
Only problem is that there are no injection-molded models of the RV
series available. I've checked the catalogs and talked to the model
shop owners.
If we were building 172's or a Swift, now, that's a different story.

Thank you for your inquiry.
Our Cool Jugs conversion kit is just that - a kit that converts
virtually any wide or narrow deck O-360 or O-540 series Lycoming engine
to liquid cooling. This includes carbureted, fuel injected,
turbocharged and turbo-normalized engines. Running liquid cooled the
cylinder head temps are maintained at a steady 190 deg F (+/- 5 deg F).
Cylinder to cylinder temp variance is essentially eliminated as all
cylinder temps run within 2 deg F of each other. Shock cooling and
heating are *completely* eliminated.
Cool Jugs is a complete, bolt-on kit that will allow a conventional air
cooled O-360 or O-540 parallel valve Lycoming engine to be converted to
liquid cooling. The result is a fully liquid cooled aircraft piston
engine. An engine that operates at a stable 190 degF without any* need
for airflow over or through the engine compartment.
The Cool Jugs liquid cooled conversion requires absolutely no internal
engine modifications! In fact no existing reciprocating/moving
components are changed in any manner. The conversion creates only one
additional moving part - the coolant pump, which is grear driven via a
standard accessory pad.
Normally aspirated engines can be run at peak lean EGT or even at 50
deg F lean of peak EGT at *all* power settings and RPMs providing you
with substantial fuel savings and *more* power. You also have the
option of using the higher compression 9.0:1 pistons for even greater
power. The stock O-360 engines typically run 8.5:1 pistons. Our dyno
testing shows that an O-360 with 9.0:1 pistons puts out 195HP at 28"Hg
manifold pressure at peak EGT resulting in a fuel burn of 11.7gph
without even a hint of detonation. Keep in mind this is at sea level
pressure. The best an air-cooled O-360 can do is around 12.5gph at peak
EGT, 28"Hg manifold pressure and that's with occasional detonation
occuring.
In fact as part of our dyno testing we ran a detonation survey on our
liquid cooled O-360 in an attempt to discover if and under what
conditions detonation might occur. What we found was that we could run
the engine at wide open throttle (28"HG manifold pressure) at peak EGT
and even at 50 degF lean of peak EGT and load the engine down to 1600
rpm (as much load as the dyno could apply) and left it there for as
long as 20 minutes without so much as a hint of detonation. That's
practically the equivalent of running wide open throttle with a
feathered propeller.
The reason you get more power when running at peak lean EGT is because
you aren't cooling the combustion mixture with excess fuel so you get
more thermal energy and in turn more power. You absolutely don't have
to be concerned about 'burning up' our liquid cooled engine running at
peak EGT or even 50 deg F lean of peak EGT - even at sea level manifold
pressure. In fact running at peak EGT at all times will actually
improve the life expectancy of the engine since it prevents the buildup
of lead deposits.
For reference a typical air-cooled O-360 running at wide open throttle
(28"Hg) at full rich will consume over 18gph. Even at altitudes above
3000' when leaning is possible, an air-cooled O-360 will consume more
fuel because it is (a) running much hotter, around 380-400 degF and (b)
due to uneven cylinder temps, you can only lean until the hottest
cylinder starts to misfire.
You should consider that installing a liquid cooled engine in any
airframe will require re-design of the cowling since our engine does
not require any* airflow through the engine compartment. You should
also consider where you might be able to locate the radiator. You will
need approx. 5000 CFM of cooling air for the radiator. A well designed
low drag radiator installation should incorporate a relatively small
air intake and a ducted air plenum to the radiator that provides for at
least a 3-4 times expansion of the air intake.
*Note: A small volume of 'breather' air is recommended for cooling the
alternator and generally keeping the engine compartment ventillated
against any buildup of fumes. You may also need separate cooling air
for the magnetos and possibly the fuel pump.
The radiator for the O-360 engine is fairly small (14" h x6" w x6" d)
and could be mounted in the engine compartment or remotely depending on
the airframe. We can have a custom radiator built to meet your needs.
A properly designed installation would be to have no more than a 24 sq"
intake and a ducted plenum that gradually expands to meet the radiator
face which is actually 12"x6" (72 sq"). The expansion rate should be
limited to 15 deg in order to prevent undesirable turbulence from
developing within the plenum. This may in some cases result in an
expansion plenum that is too long for a given airframe installation to
be practical. In such cases internal vanes can be incorporated in the
plenum in order to spearate and maintain a 15 deg expansion path.
For more information take a look at the following site:
http://www.inforamp.net/~raac/CoolingSystems/CoolingSystemsIndex.HTML
Weight
------
A typical conversion will add an additional 30-35 lbs to an engine
installation. This weight includes all of the components, radiator,
hoses and coolant. The coolant is the largest percentage of additional
weight since water (glycol/water mix) weighs 8lbs/gal and the typical
system requires 2 to 2.5 gallons of coolant. A significant portion (12
lbs) of this weight can be offset by installing a lightweight starter.
Given the potential performance improvements both in terms of drag
reduction and engine life expectancy we feel confident that the
additional weight of a liquid cooled engine will be more than offset by
its benefits.
While we can't address the potential of additional weight savings in
every airframe we can tell you that in converting a Piper PA28-180
to liquid cooling we expect to offset a significant portion of the
additional weight with a *much* lighter cowling. The redesigned cowling
will be built from carbon fiber and we anticipate that it will be
approx. 10-12lbs lighter than the original cowling. This savings along
with the removal of the aircooled baffling and changing the induction
air box will result in an additional 7-8 lbs of weight savings.
Overall, with the lightweight starter (12lbs), cowling (10lbs),
air-cooled baffling (3lbs) and induction air box changes (5lbs) we have
managed to achieve 30lbs of weight savings - virtually offsetting all
of the weight gain of the liquid cooled O-360.

Jim,
I drilled a small hole in the large washer that is used as a retainer on the
outside of the rod end bearing where it is bolted to the throttle arm. I then
went down to my local Ace Hardware and bought a small selection of lightweight
springs of various lengths. I then bent a small tab and mounted it underneath
the forward right nut that holds the carburator to the intake stud. It took
just a little experimentation to get a spring that would stretch easily through
the full swing of the throttle arm without applying too much tension. I also
played a little with different tab lengths and dimensions. Overall, it probably
didn't take me more than a half hour or so.
The spring on the mixture cable was a little more difficult because of the mixture
arm's location and swing pattern. However, a little experimentation there and
I was able to attach it to the washer (like the throttle) and to the mixture/throttle
cable bracket.
Cheap insurance and not hard to do.

Albert,
I set up my brackets on my wing jig to be just about at shoulder level. This
seems to allow a reasonable reach to the leading edge and puts the trailing
edge about 28" above the floor. This seems to provide a good height range
from which to work.

Well, this the bare minimum to qualify as a jig. What you need is a way to
support the wing's front spar and rib structure while you put the skins and
other stuff on. Van's recommends 2 posts about 133" apart with a angle
brace about shoulder height on each post to support the spar and keep it
level. That's all you need but many builders have been more elaborate,
sometimes building both wings at once and some even made the jig or frame on
caster so they can roll it out of the way. Not the kind of jigs other RV
models require!

That's right. You don't need a jig in the sense of a kit that is not
predrilled. You just need something to hold up the wing while you work on
it - doesn't have to be trued. At a couple of points (like mounting the
tank) it has to close to true - about 1/4" is okay. The instructions tell
you how and when to do it. The jig in the empenage documentation shows two
uprights 133" apart. That is the jig they are talking about. Just install
a couple of brackets to hold the spar. Pretty simple.

Hi All,
I'm helping a friend drill the fuselage aft side skins on an RV-6. Last
week we drilled (backdrilled thru the bulkheads) the left side skin. We
didn't notice at the time but the panel just behind the baggage bulkhead is
loose, meaning you can push it in with your hand to oil-can it. On the
right side we stopped drilling after the j-stringer next to the longeron was
drilled 'cause it also had loose skin in the same place.
He had his straps in between the bulkheads whereas when I built mine, i put
the straps next to the bulkheads. Does the strap location make a difference
or is this skin just formed this way? We didn't have time to shift the
straps around tonight to find out so I thought I'd ask the List.

There I was at 10,000 feet.
Once upon a time I was cruising along in my RV-4 when all of a sudden I was
set upon by really rough air. Not wanting to crack the canopy with my
noggin, I abruptly reduced my power setting. To my dismay I was holding
the power control in my left hand. It must have failed somewhere between
the black knob and the the carburetor. To my good fortune I had been a
subscriber to the "RV List Digest" and only the week before had installed a
"power on spring" to my throttle arm. However, because I sometimes think
"outside the box", I had installed the spring (with a length of 1/16th inch
stainless aircraft cable) so that the spring was fully collapsed with only
partial power (16 inches MP).
After I broke out of the rough air I joined up with a large flight of
C-150's that were heading my way. They made me fly lead because I didn't
have a formation endorsement (not to mention that I was speed control
chalanged). We had a great time flying along for what seemed like hours. I
wish I could have seen all the things that they were pointing out on the
ground.
I made an almost normal landing (one mag off on long final). I pulled my
mixture in the round out. Darn if I didn't have to land with a Red knob in
my left hand.

Albert-
I don't like to squat or sit on the floor so I opted to mount my spar at
about eye level. The only time you'll spend at the top (front) of your
wing is drilling the front of the tank and leading edge skin (oh, you're
building a -9, don't have do do that!) and perhaps dealing with the tank
to LE attach platenuts. If the -9 wing is similar to my -6A, you'll
spend MUCH more time doing stuff like flap on/flap off, aileron on/off,
fitting/attaching aileron brackets, fitting gap seal, flap brace etc. I
have a small office chair on wheels that's low enough to roll back and
forth under the spar and have done much work sitting. At this height,
you can balance the trailing edge of the flap and aileron on your knees
for attachment and removal. Has worked very well. Just be sure to pad
the end of your spar- it'll put your eye out!!! ;)

Subject: | Re: RV-9A Wing Jig |
Fellow builders -
I built my wings several years ago but found that when I had completed the
wing , less the cotrol surfaces, that it was easier to flip the wing over so
it sat leading edge down. I moved the jig arms down so that the wing leading
edge was about 6" off the floor and that left the trailing edge at a good
working height and was much easier installing the aileron hinges, flap
brace, and control surfaces.

I'm pretty sure that's your problem.
If you get the straps in between bulkheads you'll pull the skin in
beyond the normal line, and then when drilled and the straps released
that skin will be loose.
You had it right - tighten the straps on top of the bulkheads to avoid
this, and to avoid bending longerons.

Rick, you could use DC 4 compound or DC 111 compound as a substitute. 4 is
designed for electrical applications and is a bit stiffer (more viscous) and
111 is much stiffer but should work for you if applied carefully. Dow Corning
compounds are distributed thru many local ball and roller bearing supply
stores.

I've noticed vans is now adding the bulkhead and changing to epoxy pants.
But, could you elaborate on the balancing procedure you used on the wheel
pants.
I also wonder why balance would make that big of difference to a stationary
(non-rotating) wheel pant?? Why wouldn't we spin balance the tire- rims??
As compared to its physical alignment with the airflow, balance would seem
to be secondary. I'm very curious, as it's been posted as a remedy for some
time...

First put a bulkhead behind the wheel (I don't see them on Van's
products, but Sam James has a nice cut out that can be glassed in) to
keep dirt out of the rear of the pants, then balance them, IMHO.

Depends on what you mean by rotated a bit Scott. The studs are threaded and screw
in to the cylinder head. Now if you mean you over tightened it enough to have twisted
the stud then you would have to drill and tap and then usually have to put
in a heli coil.

As a data point, Van's is starting to get their wheel pants from G.
Orndorff which are not only lighter, but do have a bulkhead (mains,

Let's say, theoretically, that your a/c quality engine
assembled by a/c quality personel theoretically had an
exhaust stud that, theoretically, didn't get tightened
enough when it was assembled by those a/c quality
personel...
Did you tighten a 70 in/lb nut to 70 ft lbs, or did the nut
bottom out & turn the stud, or was the stud just loose to
start with (see p. one above)? If it were mine & the 70 ft
lb didn't happen, I wouldn't worry too much, except to be
sure the stud isn't too loose. I once had an MG Midget (only
slightly more sophisticated than a/c stuff) which had it's
combination intake/exhaust studs back out on a regular
basis.

The longitudinal balance is reduce the damping time when the gear legs begin
oscillating. The out-of-balance wheel fairings act like a weight on the end
on a thin rod -- when set into oscillation, the weight causes the
oscillation amplitude to increase.
Some C172 owners (myself included) balance their wheels to reduce wheel
shimmy. I don't know if it helps on an RV.

I've been starting to pick up some vibrations in my 6A. Its not that noticeable
yet, but I can feel an increased overall roughness. I can also definitely feel
it if I touch the panel, as do the instruments, as the altimeter needle is
starting to bounce around. My mag checks are good and my 4 egts appear normal
within less than 100 degrees of each other.
I suspect that my 4 1/2 year old wood prop is starting to go out of balance,
mostly because when we used to have these problems with ultralights, a good prop
balance job or a new prop would typically make it go away. Then, when I
switched to Composite props which stay in balance, the periodic vibration
problems never returned.
Any comments? Is re-balancing of wood props considered standard maintenance
every 4-5 years?

Gene, it you can double nut the stud and turn it out, this might be the
time. The old stud can be replaced with an over size stud. On the other
hand if it is tight and holds the proper torque, forget it. Many studs come
out when the nut corrodes so that they come out when you try loosening the
nut. That all is the time to get an over-sized replacement stud. They come
in about .003 increments so your can get .003, .006, .009 oversize and are

I balanced mine, and am not certain that balance is the real issue. What I
think is happening is that by adding weight in the nose of the assembly, you
greatly increase the moment of inertia of the wheel pant, which changes
(slows) its natural vibration frequency. I'm guessing that the natural
frequency of an unbalanced set of wheel pants can be close enough to that of
the gear legs that when one starts vibrating, the other follows.

Could anybody out there, measure for me across the F-805 and F-806
bulkheads and tell me what distance you have skin to skin.
conversely, if you have not installed the seatback support yet, could
you tell me what yours measures vertical flange to vertical flange ??
I am having some difficulty fitting the seatback support weldment.
it seems that I have a 1/4" gap after fitting all brackets and plates.
Van's send me some measurements and I was within 1/16" of those, sadly I
lost the email.
Van's solution is to use spacers between the flanges and the F-805 F-806
bulkheads, problem is the predrilled holes on top of the flanges won't
mate up with the canope rail supports.
likewise my front canopy bow is too narrow by 3/8". I have seen mail
regarding the bow being too narrow, I haven' t seen mail that the
seatback support had problems (yet)
Thanks in advance

We have a small problem (I hope) with the fit of our spinner.
We are finishing up fitting the spinner and have drilled the front and read
bulkhead holes and while making sure there was enough of an opening for the
blades to twist we noticed that the blades were contacting and slightly
flexing the rear bulkhead.
A call to Van's resulted in don't worry about it - less than a perfered
answer. Of course we should have thought to check this in the beginning -
But.
We've fitted the cowl and have a good 1/4" clearance the bulkhead.
As we see it we have three options: (Would appreciate additional ones)
1. Cut out the center of the front bulkhead and rivet in a 1/8" spacer plate
to shift the spinner 1/8" closer to the cowl. This will allow us to add a
couple washers - giving clearence between the prop blades and and the rear
bulkhead in flat pitch and retain 1/8' clearence between the rear
bulkhead?rear of spinner and the cowl.
2. Cut out or relieve the small area on the rear bulk head that is in
contact with the prop. Not sure sure how. This retains the 1/4" clearence
between the rear bulkhead & and cowl.
3. Follow Van's advice and forget about the fact that our C/S prop contacts
the rear bulkhead and flexes it.
We are leaning toward option # 1, but would appreciate any
commments/suggestions.
Thanks in advance.

First you glue the wood strips to the legs, then you wrap with epoxy soaked

inside the fairings.
But I don't see how this applies to the RV-8(A) gear.

Kyle, this matches my experience with my RV-3. The shimmey diminished
significantly when I changed to the heavier Condor tires (about 2 pounds heavier
than the training tires which came with the kit).

Subject: | Re: RV-4 Canopy Trimming |
I had the same problem. I trimmed enough off the back end of the canopy so
that the sides would overlap the bow along the back seat. Then the rear bow
had to be cut and shortened quite a bit so the canopy wouldn't shove it down
into the aft fuse skin. The aft bow then had to be reformed to fit the
Plexiglas...not easy because it is 6061 T6? (hard). I spliced it back
together by inserting soft alum tube.
I think shortening the canopy that way complicates fitting the side skirt
around the back. I cut and lapped the side skirts at the rear vertical
member of the canopy frame but they want to buckle as they travel the
shorter curve. I'm now working my third set of aft skirts. If I knew
anything about fiberglass I would try that...maybe later. Sorry I can't
offer a solution.

Daniel, the pre fab spars are extra-approx $950 extra. You need to contact
Phlogiston and they will co-ordinate with Vans. The spar pieces are sent to
Phlogiston assembled, and then sent back to Vans in order that your entire
wing kit can be shipped together. Many of guys will tell you to save your
$950 and do it yourself. Others have told me differently. It will help resale
of your plane someday, and I did not want to bother with the larger
rivets-too much possible damage in my mind if I had to drill too many of them
out. Contact me off list if you want to know more. Bob in Arkansas skinning

Hobby stores have short sections of transparent blue silicone hose available,
but I think the wall thickness inadequate for vacuum service. It's used for
exhaust tubing on RC models. You may be able to buy longer lengths on

That said, I added one washer on each of the supplied spacers prior to

I just went through this last month and had the same problem. I trimmed

the problem. I then took a ratchet strap and put around the fuse and
canopy midway of the canopy and pulled it down. It does not take much
pressure and then drilled and put in a few rivets spaced about 10 inches
to hold it in place. I am now waiting on my second set of skirts as I
was not pleased with the first set. Go easy when trying to fit these.
I would also suggest you remove the rollbar while fitting the canopy.
I also sprayed the canopy with spraylat available from Aircraft Spruce.
It forms a strippable protective coating that will protect the canopy..
Hope this helps.

I'm not sure what you are building, but on an 8A most Home Depot / lumber
stores have standard wood molding strips that would go between a floor and
wall for decorative purposes. I used a plain strip (no fancy curves on the
face) . . . 2 1/4" wide. It tapers from almost a point on one edge to a
"rounded" 5/8" on the other edge. These are cut, per plans, and fit inside
Van's leg fairings nicely. FMHO, Cutting the stiffeners is best done on a
bandsaw with tiltable table (my cheapy Sears does this) because you are
cutting along the length of the stiffener at an angle, necking down the
piece, plus the cut surface is at an angle so the left/right sides can mate
together (this is shown on the plans). As to front/back, apparently it
doesn't matter, and mine fit either front or back. Good luck.

Daniel,
You really don't need to pay anything. Save the 9200 pesos and do it yourself.
There is really not much to it, the holes are all pre-drilled, all you have to
do is
deburr and polish the pieces, prime it and rivet it together. Several replies
have
mentioned using a large rivet gun, I used the Avery C frame tool with a 4 LB small
sledge hammer (as explained in the manual) and found it worked great. Only had
one
bad rivet to drill out. Save the money and just build it.
For what it's worth, the three biggest hurdles (so I was told) in this project
are
the spars, the tanks and the canopy. Doing the spars yourself gives a certain
confidence to attack the other two later on. I am looking forward to starting
my
tanks shortly.

Daniel, The pre-fab spar is an option that adds to the cost of the wing
kit. It is completely unnecessary as the spar is very easy to build. The
fact that Van offers a pre-built one brings up the intimidating doubt that
this is an important piece that needs to be professionally built but in fact
it is not the case. The spar is very straight forward and simple to build.
It doesn't even take that long to do. Save the money, do it yourself.
Thousands of homebuilt spars are out there.
My comments refer to kits produced after the mid nineties when the wing kits
became pre-punched. They must have been a bit more of a challenge before
when the builder had to drill all of those very important 3/16th holes.

Some time ago Joe Czachorowski mentioned a good way to temporarily place
the baggage door ribs on the baggage door prior to riveting. His method
used a "3M 2216 Epoxy". Anyone know where to get this? I've sent an
e-mail to Joe as well (and will post this on the rv-8 list also).
Thanks in advance.

Daniel,
I made my own using a C-frame tool on my workbench, which sure beats
kneeling on the floor to do the rivetting. The base of my C-frame has a
steel rod extending from the die to a steel plate on the floor. As
most of the parts are ready for final prep (rec'd kit Apr. '99) it took
this first-timer about 60 hours to complete, but I work pretty slow,
YMMV! Very pleased with the results.
If you'd like more info and photos, contact me off-list.

The method of attaching the wingtips would have to be modified. The rib

Kurt, I can't think of a structural reason not to switch em, provided you
push them inboard enough to allow for the wing tips to fit up. I didn't find
that riviting them as per plans was any problem at all though! Check with
Van's before you switch em though!

Subject: | oil cooler doors - final answer |
Enough speculation. An oil cooler door DOES work well to regulate oil
temperatures and a permanent cockpit controllable sliding door is being
installed on my 6A.
Previously my oil temps were much too low. Even in an extended climb I would
not see much over 140 degrees. Not good!
Today, as an experiment, I sealed with duct tape the air entrance to the oil
cooler; a 3" hole in the rear of the baffle that feeds cooling air via a
10" length of scat tube to the firewall mounted cooler. After about 10
minutes flying at as high power as I can get up here my oil temps climbed to
and stabilized at about 185 degrees. I flew for another 1/2 hour or so
including a full throttle 90 mph climb to 14,000 and watched the steady
indicator at that perfect 180-185 level. I then landed, pulled off the duct
tape, went to have lunch while things cooled a bit, and took off again. Back
to 140-145 degree temps.
Bottom line - done deal - final answer! Restricting airflow at the intake of
the oil cooler does work in regulating temperatures.
I also feel that a controllable door is a necessity. If I was content buzzing
around the Fraser Valley in similar conditions, a permanent patch would be
OK. But, if instead I wanted to hop over the hills into Denver, (4000' lower
and 20 degrees warmer), and then face a long climb from 5000 - 14,000 to
sneak back over the pass, I'm sure a blocked oil cooler would have caused
overly warm temps.
There was some discussion earlier that oil does not even go into the cooler
until about 180 degrees. This is not true. We do not have thermostatically
controlled valves accessing the oil cooler. Its just an open hose and oil
flows through the circuit at all times. My hangar partner who flies Falcon
Jets for a living said that some advanced turbines have such a feature. And
perhaps some bigger more advanced recip engines do too. But our simple little
360s and 320s don't.
A sliding door and the cooler intake seems like a simple thing to build
probably from scrap laying around my shop. Its the same as the cabin heat
door that most of us already have. Problem solved!

Andy,
Grab you old direct drive Lycoming Overhaul manual and take a look at drawing 2-3
and 2-4. It depicts the oil lubrication path for 4 and 6 cylinder engines
respectivly. You'll notice that the 6 cylinder engine has an optional
thermostatic bypass valve available (veritherm). I happen to know it's also
available for 4 cylinder engines. So, save yourself some work. Call Lycoming and
see if they have one for your engine to replace the oil cooler bypass valve.

Just my uneducated speculation here- the common thread in this
discussion is that blocking the REAR of the cooler often (but not
always) has little effect on cooling efficiency, but covering the FRONT
yeilds good results- (recalling several posters who sucessfully
duct-taped or had a butterfly type valve in the duct leading TO the
cooler) Perhaps there is enough turbulent, cold airflow within the
cooler itself when blocked at the exit and exposed at the plenum to
effect some degree of heat transfer...

Andy maybe your Falcon pilot should read Lycomings web page.
Just a small quote from there.
"Most oil systems offer as optional or standard, a thermostatic bypass
valve in this same location which also contains a pressure relief feature
to bypass the cooler in case it is clogged. As the name implies, this unit
regulates the temperature of the oil by either running it through the oil
cooler if it exceeds a preset temperature, or bypassing the oil cooler if
the oil temperature is lower than the thermostatic by-pass
setting."
Please note the part about by passing the cooler untill a certain
oil temp is reached.
Just out of curiosity what does he think the Vernatherm valve is for?

Should work peachy if you plan on digging out all the foam when you are
done. Lay plastic in there first and the foam should come out easily. To
leave it in would be begging for a weight and balance problem when water is

Subject: | Re: oil cooler doors solve a symptom not the problem |
For those following this thread, the last two posts by Jerry Springer
and Bruce Gray bring up a very serious potential problem for RV
owner/operators: it appears that very few of our current or future
"certificated repairman" have never seen the inside of the Lycoming
Engine Operator's Manual, the Overhaul Manual or the Parts Catalog
(Mazda and Chevy guys are off the hook, for now.. If
you look at the Lubrication diagrams in the Overhaul Manual (2-3, 2-4)
it is obvious that a vernatherm valve between the oil pump and the oil
cooler (items#1 & 2) in the oil flow journey would allow the the oil
temp to reach 180 deg. F before the oil was diverted to the oil cooler.
This is an inexpensive part that is very simple to install, BUT it has
to be on the engine to work. You can use this neat device called a
telephone to order these manuals from Lycoming or call/email Andy at
Builders' Bookstore (Yeller Pages). The same device will get you the
vernatherm from Lycoming or maybe your local FBO.
It's incomprehensible to me how people can spend thousands of dollars
and hours on a project and not be able to fork over $50-60 for the
material that will actually save their bacon, while they page thru a POH
(downloaded from the 'Net) compiled by somebody else and probably has a
totally different engine and engine controls/devices.

Agreed, PROVIDED door is in front of cooler. I also confirmed this by

Please post a picture of the sliding door when it is built. In my 6A with
O360A1A I could not use the cabin heat door as a model. Nor could I figure
out a way to fashion a sliding door that would effectively block the inlet
to the cooler. There isn't much room in that area in my plane.

Hi Kurt,
I'm not familiar with the RV-8 but on the RV6 the outboard aileron bracket is
"L" shaped and fits with one leg of the "L" on the rear spar and the other
leg of the "L" is flush against the outboard rib web. If you were to reverse
it, the aileron bracket would no longer sit flush against the outboard rib.
It may be different on the 8 so check it out.

Hi,
RV-8
When doing the final fitting of the legs to the Fuz the left leg torqued up
fine but we are having some difficulty with the right leg.
When torquing the bolts through the U803 the rear bolt tightens up much
sooner than the forward bolt leaving a larger gap between the U803 and
U805-1 at the rear than at the front. Also the U803 only contacts the leg at
the front leaving a gap a piece of paper can be slid trough at the rear.
Thought we had the problem figured out when we noticed the bolt holes
appeared to be angled back slightly so that even without the leg in the way
we had to have a small gap at the rear between the 803 and 805 to get the
bolts all the way through the holes. We cleared the holes with a drill so
the 803 could be held flush against the 805 and the bolts pushed all the way
through easily. Very little material was removed from the holes.
However subsequent fitting of the leg had the rear bolt tightening up early
again with the large gap at the rear!
Our next move will be to get some bluing compound and tighten the assembly
up to figure out where the contact areas are.
Any ideas much appreciated.
Cheers,
Arthur Whitehead

I've been using a cheap gun called a Docken sprayer. I bought it many years

with a small syphon tube that sits down in a paper cup that you fillwith
paint. The cup attaches to the gun via a c clip about 3" in diameter. Once
you are done painting you throw away the paper cup and run a little lacquer
thinner through the gunand you're done. Not much more than putting the cap
back on the spray can. My biggest problem right now is finding paper cups.
Everyone has gone to plastic and they dissolve in a heartbeat with thinners
and epoxy paints. I have actually written to Sweetheart cup co to see where I
can buy the right size. Now that I have the right formula for thinning and
pressure I think this is the way to go for easy priming. Not so good for
finish painting. Also. you can't tilt it much or the paint will run out the

Hi list,
I'm working on a 6 QB.I've built up the F635 bellcrank for the elevator
push/pull tubes and I believe that there is a problem with where it
mounts on the F629. If I'm reading the plans right, it should mount
through the horizontal angle in line with the rivets which are spaced
about 1 1/2" on center and through the (basically) vertical angle on the
F628. My problem is that when I lay it out, the location of the hole in
the F629 is only about 9/64" from the center of the last rivet. With a
3/16" hole, I'm drilling into the edge of the rivet. Then there is a 3"
gap where I'm guessing they thought that the bellcrank is supposed to
mount. On the F628 they left several rivets out at the bottom, but the
bellcrank layout appears to be between two of the ones they put in and
clear by about a half inch so that one should be OK. What now?

John,
It takes a pretty long leg to justify climbing to 17,500 for fuel
consumption reasons alone. I have found I can cruise at 165 knots at 17,500
at about 7.5 gph (fixed pitch prop, O-360, RV-6). I'm happy with that but
you do lose some speed with all the time spent climbing. That is about 1
gph less than I would run at around 10,000 feet at 165 knots.
I love it up there for reasons other than economy, like great tailwinds and
terrain clearance over 14,000 foot mountain ranges. It also gives a sense
of security over rough terrain in the glide range it gives you in case of
engine problems.
As much as I like it, I consider 2 hour legs about minimum to justify it.
My web page (under Mountain Tour 2000) has some details about a trip I took
last summer where I operated quite a bit a high altitudes.

I responded to a question about high altitude flight from memory but I
forgot something important. I said I get around 165 knots at 17,500 and 7.5
gph. When I looked at my own data I found my own fuel burn at that altitude
was slightly more but could be much less. That is because I have to lean to
best power at that altitude to get that much speed. At a best economy
leaning the fuel burn would be much better but I don't know what the speed
would be. Maybe around 155 knots at 6.5 to 7.0. Not sure. I'll have to

Guys,
I thought of a solution. Let's see what you think of it. If I rivet or bolt
a piece of angle to the aft side of the semi-vertical angle on the F629, I
can drill through that to mount the bellcrank. This would move the bellcrank
5/8" aft and I would need a longer forward push/pull tube. Would that mess
up the geometry? Also the plans show the length of the forward push/pull to
be 47 1/2". Is that the overall length to the bolt centers or the cut length
of the tubing itself?
Thanks,

Subject: | Round Head #4 Rivets |
One of the first tough things I remember as a new builder was using the gun
and bucking bar setting 1/8 rivets in the various skeletons. I recall that
one in my tail was tried a few times and got worse each time. A call (cry)
to Vans taught me that I could use a 3/16 bolt with a nylock nut there for
the fix.
Awhile later I bought a computer and got on this RV List that I had been
hearing about. I soon started to catalog neat tips and suggestions. One
thing that caught my attention right away was several people discussing how
to get these round head 1/8 rivets perfect every time. They were talking
about using hockey shin guard tape over the rivet sets on the gun. I
thought, hey that's cool but it must be the same as vinyl electrical tape.
So I tried it but still got the occasional smile next to a rivet. I then
started trying all other different kinds of tape with again the occasional
smile. I just couldn't get why those Listers were so adamant that shin guard
tape is the ultimate solution.
Finally about a year ago I went to Burnaby 8 Rinks and got some of this shin
guard tape. It comes in a massive roll around the same width as electrical
tape. It is enough for about a hundred builders to complete their projects.
It is almost rubbery and stretches evenly when putting on shin guards. It is
much thicker than electrical tape.
I took it home and low and behold I haven't pooched a rivet since. This
stuff is the goods. Perfect rivets every time. Why? I don't know but I do
know that every one should try this stuff. I can't say this enough, it makes
a difference.
Go to your local hockey store and get some, put a small piece on the head of
your gun set, it will never slip again. I change it every 5-10 rivets. Use
your local yellow pages under "sporting goods".

Boy, this thread just won't die. :-)
Actually, this lister has found that both statements can be true. When I
found a used O320-E2D for my RV-6A, the oil screen housing did not
have a vernatherm by design. During my early test flights, the oil temps
went way up. We realized the oil wasn't getting to the oil cooler as well
as it should because the oil was flowing back to the sump. With that, I
replaced the housing with one that had a vernatherm installed. The oil
temps immediately went down to normal for that time of year. BTW,
the time of year was winter; so, temps well over 400F should not have
been seen. Without the vernatherm, I saw temps rise to almost 450F
on a 35F day. Not good.
If memory serves me, and it sometimes doesn't do that very well, the
vernatherm expands as it gets hot. When it gets hot enough, it closes
off a hole back to the oil sump and forces the oil to the cooler. Since
the vernatherm is very much like the thermostat in a car cooling system,
there must be huge differences in the temps that we'll see in our
systems. Mine has to have the oil cooler door so that I can warm the
oil because the vernatherm opens the flow to the cooler well below the
180F mark. Others don't. If the vernatherm sticks at the cold position,
the oil can't get to the oil cooler and could possibly heat up the oil to
dangerous levels, even on very cold days. Mine did just that when
there was no vernatherm; so, it stands to reason that a stuck one
would have to do the same thing. As I said, my memory banks may fail
me; but, that's what I experienced.
I did a lot of head scratching before I realized how the vernatherm
controlled things and still may have it wrong. I'm not an expert. :-)
I'm going to archive this note because others may have similar
problems in the future.

Listers....
Will you allow a non-RV guy to infiltrate with a couple of pi**-a**ed
questions?
I'm doing the engine install on my 180HP injected Lycoming. First up, a
location for the fuel pressure take off. My bendix injector spider sits
on the right side of the engine, and came plumbed as follows, looking
from the pilots seat forward. The fuel intake is at the 3 o'clock
position, low on the spider body. There are what appears to be 7
identical ports, higher on the body. The four that are plumbed for
lines to the injector are at the roughly 1,5,7 and 11 o'clock
positions. There are two more unused at the 8 and 10 positions, and the
one at the 2 o'clock position came with the pressure tap fitting. My
question is, can I take the pressure tap from the 8 o'clock position
with the same results? I'm presuming that this spider is universal for
a 6 cyl Lyc, plus one for fuel pressure, and that they're pretty much
interchangable amongst the 7 points.
Second question, manifold pressure. Never had one before. I understand
that I take the readings from the primer port on the right rear
cylinder. Question is, what material can I hook up to that 1/8th" AN
fitting? Ultimately, I've got to hook up to some "poly" line into the
cockpit, and if I could go poly all the way it would be simple. But I'm
concerned about the heat at the cylinder. Solution would be some
stainless or copper line for the first few inches like a normal primer
install, but then it gets complicated as I try to tie it to something
solid, while not having a cantilevered end of the solid line vibrating
towards ultimate destruction. Experiences?

Mark,
I didn't use the wood stiffeners on either the mains or the nose.
I have not had any shimmy on the mains at all to the best of my knowledge.
I corrected nose wheel shimmy by torquing the nose axle bolt to the spec in
the manual, 7-10 ft lbs. & inflating the tires to the correct pressure.
I didn't balance the wheel pants either.
I have found that the tire pressure plays a big part in the low speed shimmy
that I have experienced, I keep my tires at 30-35psi.

Quick comment: those few who, like myself, have no vernatherm installed, and
have taken the cheap n' easy route of plumbing the remote oil filter in

is bypassing the cooler circuit. Retaining the oil screen might mitigate
this disadvantage somewhat, as you'd always have that system working on the

Of course the one of the joys and priviledges of homebuilding is to

I have to confess, I don't understand the logic behind leaving out the gear
leg stiffeners in the first place. They are recommended in the manual, they
are easy to do, cheap to do, kind of fun to do (hey, I don't get much of a
chance to do woodworking on an RV), and no one who has done them is
complaining of shimmy. Okay, they do add 2 or 3 pounds.
I mean, if we were talking about spar web stiffeners, no one would be
debating their inclusion. (shudders at the thought). Perhaps the manual
should be a bit more forceful on some of these "optional" construction
details like gear stiffeners. The gear is a part of the secondary structure
of the aircraft and you would think the design deserves to be finalized
after 25 years of production.
Not that I am complaining. Love the airplane, love the List.

I experimented with different tire pressures. (My shimmy is at low

To show how variable this is, my WORST shimmy was at 30-35psi, least at

Hiya Larry,
Good question indeed. In my experience, the Vernatherm is not a "snap
acting" type of thermal switch, but a device that begins to move at some
temperature and continues to move as it gets hotter. I've personally tested
one by placing it in a vice, and heating slowly with a propane torch. It
did not suddenly move to a position and stay there, it just started creeping
in length until it would not move any further. I'm finding that with my
present spin on oil filter housing with vernatherm, the oil temp will not go
above 140 degrees in the winter unless I mask off at least 1/2 the surface
area of the oil cooler. When this is done, the oil WILL go to 180 degrees
and stay there. So, I reckon there must be SOME amount of oil going to the
cooler at all times. I vaguely recall reading that having a stagnant volume
of oil in an engine lubrication system isn't a good thing, so maybe Lycoming
designed the valve to always allow at least SOME amount of oil to make it to
the cooler just to keep the oil moving.
Just my WAG at it.

Subject: | Re: Wooden Gear Leg Stiffeners - why not? |
In the words of the great Van's technical manual: "Shimmy is a nebulous
thing".
Logic:
1) Van's told me to try it without the stiffeners and see how I like it -- I
did and I like it.
2) It saves time and weight not to install stiffeners
3) One function of the gear is to absorb the shocks of landing -- it does
this better w/o stiffeners.
4) Hearsay: Nose gear leg breakage has been attributed, among other things,
to stiffeners.
In general automotive, motorcycle and, I think, aeronautical terms, a shimmy
is a side-to-side oscillation of a wheel, usually fixed frequency -- a kind
of mechanical resonance. It is usually considered objectionable because it
diminishes steering authority and the oscillations can be felt though the
frame of the vehicle. In some cases it is divergent in amplitude -- the
"speed wobble" sometimes found in older bikes without adequate steering
dampers.
In the case of my 6A, the gear legs do flex during take off and landings.
I think this is their purpose in life. I can't perceive this flexure in the
cockpit except for grass takeoffs/landings. Others have observed the motion.
However, I can not feel any "shimmy" and the directional control of the
plane is positive. I maintain precise directional control with rudder only
at speeds above about 7 knots, taxiing included. The only time I use the
brakes is during runup and sharp turns while parking. I use about 1500-2000
feet of total runway, after which the speed has decayed to a speed at which
I can make a turnoff without brakes. I do land pretty hot -- about 65 KIAS
over the threshold. This is with a constant speed prop -- it would not be
possible with a fixed pitch prop.
Scott McDaniels: How about a word from you on the gear stiffener issue?
Does the demo 6A have stiffeners? We listers clearly need some advice from
the experts!

A separate regulator is desired when the battery and the regulator are in
different locations. The charging voltage required by the battery lowers as
its temperature increases. In automobiles, the battery and the alternator
are usually in the same temperature environment, ie, the engine compartment,
hence no problem with the regulator being located in the alternator.
However in my RV-6A and the VariEze, the battery is in the cabin, and that
is where the regulator should be. The regulator is temperature-compensated
for the varying requirements of the battery.
If you have an alternator with an internal regulator when the battery is in
the cabin, the battery will be undercharging by about .5 volt. This could
leave your battery in a low state of charge at any given time. This would
probably show up when starting on a cold morning. You can reduce this
problem somewhat by ducting outside air to the alternator to keep its
temperature down, but you don't have any control over this. It's better
just to put the regulator near the battery.

Uh, Oh. Jerry Springer caught me when I made a misleading
statement about temps. My oil temp was not 450F. The cylinder
temps were. Hey, it was written well before many of you wake up;
so, forgive me. Here is another pass at it with the corrected info.
Sorry about that. Thanks for catching that, Jerry!
BTW, I went flying today and got the oil to almost 180F using the
door. Without it, I couldn't get it there. The temps were below 30F.
Thank goodness for the new EZ-heat I installed recently. Nice to
start with warmed oil.

Boy, this thread just won't die. :-)
Actually, this lister has found that both statements can be true.
When I found a used O320-E2D for my RV-6A, the oil screen
housing did not have a vernatherm by design. During my early test
flights, the oil temps went way up. We realized the oil wasn't getting
to the oil cooler as well as it should because the oil was flowing back
to the sump. With that, I replaced the housing with one that had a
vernatherm installed. The oil temps immediately went down to normal
for that time of year. BTW, the time of year was winter; so, oil temps
well over 200F should not have been seen. Without the vernatherm,
I saw oil temps rise to over 225F on a 35F day. Not good.
If memory serves me, and it sometimes doesn't do that very well, the
vernatherm expands as it gets hot. When it gets hot enough, it
closes off a hole back to the oil sump and forces the oil to the cooler.
Since the vernatherm is very much like the thermostat in a car
cooling system, there must be huge differences in the temps that we'll
see in our systems. Mine has to have the oil cooler door so that I
can warm the oil because the vernatherm opens the flow to the
cooler well below the 180F mark. Others don't. If the vernatherm
sticks at the cold position, the oil can't get to the oil cooler and could
possibly heat up the oil to dangerous levels, even on very cold days.
Mine did just that when there was no vernatherm; so, it stands to
reason that a stuck one would have to do the same thing. As I said,
my memory banks may fail me; but, that's what I experienced.
I did a lot of head scratching before I realized how the vernatherm
controlled things and still may have it wrong. I'm not an expert. :-)
I'm going to archive this note because others may have similar
problems in the future.

Ed,
I went out and looked at my setup. I have no rivets near the holes. In
fact the holes for mounting the bellcrank appear evenly spaced between
the existing rivets on both the F628 and the F629 angles.
I'd double check where you are laying out your holes. The plans didn't
give dimensions as to where the holes should be, just the drawing. I
remember some consternation while figuring out exactly where to locate
the holes.
If the rivet spacing is screwed up on your F629, it wouldn't be the
first error found on a QB.

Wow, what a great idea. You should write Lycoming and tell them to
redesign the engine so it is configured as you describe, then it would
work the way YOU think it should.
Here in the real world where the rest of us live, the oil cooler bypass
valve is NOT located "between the oil pump and the oil cooler".
Instead, Figure 2-3 on page 2-2 of the (current) Lycoming overhaul
manual shows that the oil cooler bypass valve is in fact installed in a
path between the input and the output connections leading to the oil
cooler (in other words, the bypass valve is in parallel with the oil
cooler). By the way, Bob Ohnmeiss (Lycoming tech support) told me
that the vernatherm (oil cooler bypass valve) is installed stock on the
O-360 A1A as shipped from Van's. The vernatherm ("Valve
Assembly, Temp control oil cooler bypass", Lycoming part number
75944) is part number 44 on figure 15, page 2-10 of the O-360-A series
parts catalog. Bob told me that even though the parts catalog doesn't
show it, part 44 is installed into the bottom of part 29, the Oil Filter
Base Assembly.

Or, you could do a little research and discover that the part is

The vernatherm is in *parallel* with the oil cooler, not in *series* with
it. The vernatherm does not shut off the flow of oil to the oil cooler, it
provides an alternate path circumventing (somewhat) oil flow through
the oil cooler if the oil is already too cold.
When the oil is too hot, the vernatherm restricts the circumventing
path, forcing more of the oil through the oil cooler.

Mike,
The pressure tap on the distribution spider is not for fuel pressure-it's
for a fuel flow guage (actually a pressure guage that's calibrated in GPH)
Your fuel pressure line should be taken from the downstream side of the
engine driven pump or at the inlet to the bendix.
For your MAP line, use automotive fuel hose of the appropriate size.

If you use any substance that has cyanoacrylate as a componant, it will not

Bob,
Only bevel the corner where the two skins meet right behind the tank skin on
the spar flange. This is only about a 2" square area. Don't bevel the skins
full length or it could weaken the splice. The goal is to make the area
where the skins overlap each other and rest on the main spar, to be at the
same level as the tank skins. I beveled them by filing the skin thinner. I
placed the skin on my workbench so the corner to be filed was in the corner
of my workbench. Then using a file, I filed the skin in that corner only,
down to where it was about as thin as the aileron skin. Then when the two
are overlapped together, they lay flat and level with the tank skins.
Yes, you do the top of the wing the same way.
Hope this helps - its hard to explain
and even harder to photograph.

Well, that's what I used to think, but I DO have a Vernatherm AND too cool
oil temps. I was stumped as to why blocking the door would help but it did.
Eventually someone explained to me how the two paths are parellel (as
someone else just did on the list so I won't go over that again.) At any

Agreed. Although it kind of irks me that even if you pay the big $$$ for a

Chuck and Dave,
If it were me I would use option 4 (assuming you choose to not just leave
it).
The bulkheads are made with a softer aluminum that what the rest of the
airplane is so it allows for some adjustment.
First add spacer washers on the rear bulkhead to get the clearance you
want, but I recommend that you don't get the spinner bulkhead to cowl gap
any smaller than 1/8".
Now using you hands you can slightly "dish" the shape of the fwd bulkhead
so that the flange moves aft by the amount that you moved the aft
bulkhead.
This is most easily done with the prop mounted on the engine. Using your
hands, lightly lean/push on the outer edges of the fwd bulkhead. Keep
moving your hands so that you work your way around it's entire diam.
Keep checking with the spinner.Do just a little at a time until you get
all of the holes to once again line up.

Subject: Re: RV-List: oil cooler doors solve a symptom not the problem
For those following this thread, the last two posts by Jerry Springer
and Bruce Gray bring up a very serious potential problem for RV
owner/operators: it appears that very few of our current or future
"certificated repairman" have never seen the inside of the Lycoming
Engine Operator's Manual, the Overhaul Manual or the Parts Catalog
(Mazda and Chevy guys are off the hook, for now.. If
you look at the Lubrication diagrams in the Overhaul Manual (2-3, 2-4)
it is obvious that a vernatherm valve between the oil pump and the oil
cooler (items#1 & 2) in the oil flow journey would allow the the oil
temp to reach 180 deg. F before the oil was diverted to the oil cooler.
This is an inexpensive part that is very simple to install, BUT it has
to be on the engine to work. You can use this neat device called a
telephone to order these manuals from Lycoming or call/email Andy at
Builders' Bookstore (Yeller Pages). The same device will get you the
vernatherm from Lycoming or maybe your local FBO.
It's incomprehensible to me how people can spend thousands of dollars
and hours on a project and not be able to fork over $50-60 for the
material that will actually save their bacon, while they page thru a POH

Boyd Braem

flame away--at least it will increase your chances of staying alive
Boyd,
This is not at all meant as a flame but just to point out that it is much
more complicated than you imply.
I am very familiar with the schematic in the Lycoming overhaul man. I
am also familiar with the fact that it doesn't tell the whole story.
If you ever sit down with just an accessory case cover and look at were
oil passages go you can finally get a good idea about what is going on.
Now it has been a while since I did this my self so every thing that
follows is from memory (meaning I could be totally wrong) but I think it
is pretty close.
First of all most Lycomings that RV builders are using probably have a
vernatherm installed (unless they are really old).
Some may have a washable filter screen and many probably have a spin on
filter adapter but either one of these can and probably are using a
vernatherm.
One of the big misunderstandings about the vernatherm is how it directs
oil to the cooler (Lots of stuff in the archives about this. Some by me,
and some by others). When the engine oil gets up to a temp matching the
value of the vernatherm that is installed the vernatherm grows in length
an closes off a by pass path. If you are using a spin on adapter this
also closes the bypass for the oil filter (thick cold oil doesn't like to
flow through a paper filter element very well).
What this means is that there are two paths for the oil when it is cold
(through the filter and cooler or through the by pass path that allows it
to flow around it. When the vernatherm elongates and entirely closes off
(assuming the seat surface and the end of the vernatherm are in good
shape) the bypass, forcing all of the oil to go through the filter and
the cooler.
Here is the problem... when the oil gets somewhat warmed up (say 120 deg
F.) it is warm enough to flow through the filter, but the temp is not
high enough for the vernatherm to do any regulating yet.
Since the cooler is mounted in the warm engine compartment, maybe even
directly attached to the baffles which get heated up by the engine cyl.,
it gets warmed enough to warm the oil in the cooler and the lines. This
in turn means that there is now much less resistance to oil flowing in
the cooler circuit, even though it has a by pass path to flow through
since the vernatherm has not yet closed the bypass path.
More simply...a vernatherm does NOT keep the path to the cooler closed
until the oil warms up.
What it does do is close the path which allows the oil to not flow
through the cooler.
If you want to test for your self... run your engine on a cold day, just
long enough to get the oil temp. up to about 120 deg. Then disconnect
the oil hose that returns to your engine from your cooler.
Put a cap on the open fitting on the engine. Now start the engine and
run it for about 5 seconds.
I think you will have a big mess to clean up (but maybe I'm wrong).
The main problem is that until you can get near the vernatherm temp, you
have two paths for the oil.
The oil will tend to take the path of least resistance but not all of
goes that way.
Because every RV (and engine) is a little different sometimes this little
bit of residual cooling is just enough to keep the temp from ever getting
high enough for the vernatherm to do its regulating job.
Devising a means to variably block air into the cooler seems to work well
for alleviating the problem though I highly recommend that you not do
anything to deal with the problem until you are flying and you find out
that you really have a problem (many builders do not, as attested to here
on the list), and then only after you verify every other possibility
(gage error, etc.).

Check the archives for a procedure that I used and worked great. I can't

the end of the year regarding this very topic. One of the replies was to
cut a small square out of the inboard skin (that's the one that lies under
the outboard skin per plans). The inside of this square is even with the
outboard skin, so they lie flush together on the spar.
The original post even contains a diagram. Works great! Looks great!

I offer my posted reply to a similar question back in December 2000:
"e
I tried both methods of getting a single layer where the skins meet. I
tried overlapping them - I used my finishing palm sander; I think a
belt sander might be too aggressive.
The joint was not very good even though I started thinning some
distance from the actual overlap area.
On the bottoms, I figured few would get on their backs and look at that
joint, so I trimmed them to a butt joint (notched one side). You know
what? That was a better looking joint and truly _was_ a single layer
thick. I was so impressed that I did my other top skins the same way,
and I recommend it.
Cut your notch and trim a bit at a time, and then use a scotchbrite
wheel on the die grinder to finish. You can get the joint so it is
barely noticeable.

If you check the archives (use the word "chamfer" as well as "bevel")

The following are questions I asked Lycoming regarding Vernitherm operation and
oil temps. My questions are in lower case. The answers are in upper case:
my 0-360 A4M installed in an RV-6A, has very low oil temps (just over 140,
even in long climbs). I have been advised that the vernitherm may be stuck in
the open position thus allowing oil into the cooler, even when it does not need
to be. because I am unfamiliar with this part please answer these questions.
THE VERNITHERM IS ALWAYS OPEN, UNTIL THE TEMP GETS TO HOT!!!
1] is this a likely scenario?
NO!
2] Is the vernitherm adjustable or will it simply need replacement? If
adjustable, how?
NO!
3] I was also advised that there is an AD on this part. If so, where can I
find a copy?
THE FAA.
4] Another person suggested that the vernitherm also restricts or adjusts oil
flow into the screw on oil filter. Is this true?
NO.
An alternative or additional step might be to construct a cabin adjustable
door to open and close air intake into the oil cooler; Your comments on this?
THE VERNITHERM ONLY CONTROLS MAX OIL TEMP. IT HAS
NOTHING TO DO WITH LOW TEMPS. THE AIRFRAME CONTROLS THE LOW TEMPS.

This has been a pretty interesting thread to say the least. It appears those
trying to control the air flow across the cooler itself have been correct.
Lets add another wrinkle to this solution, instead of controlling the air,
how about installing a ball valve right at the oil cooler which would direct
all, some, or none of the oil either through the cooler or divert back into
the return line. This valve would be controlled from the cockpit via a cable.
Just like the valves that control the hot water that flows to the heater
cores of our millions of automobiles. Same principle, different objective.

I sure don't get a warm fuzzy feeling about having yet another knob in the
cockpit to adjust something that seems like it should be automatic.
Doesn't there exist a reliable thermostatically-controlled valve that could
control the flow of oil through the oil cooler, to do what a lot of people
seem to think the "vernatherm" should be doing? From the sound of the
Lycoming reply, it sounds like the "vernatherm" is sort of an emergency
backup in case whatever the airframe mfr put in series with the oil cooler
got stopped up. If so, then maybe they were assuming a thermostatic valve?
I don't know about anybody else, but I think a hundred-dollar-or-so valve
that let me concentrate on flying the plane rather than messing about with
the engine would be a safety enhancement, especially if there was already a
backup device to slow it down from destroying the engine if it failed.
I guess I'm biased. I earn my living automating stuff a thousand times more
complicated than a thermostatic valve, and have make it cost under $10 most
of the time. It's galling that to get a reliable airplane I'm having to
install so much 1940's-vintage control stuff.

Kevin,
After mulling this thread over, controlling the air to the oil cooler seems
like the right way to go. Besides the benefit of bringing all the oil up to
a temperature that will drive off moisture, a inlet air control valve has
the secondary benefit of redirecting cooling air no longer going to the oil
cooler back to cool the cylinder heads.

This has been a pretty interesting thread to say the least. It appears those
trying to control the air flow across the cooler itself have been correct.
Lets add another wrinkle to this solution, instead of controlling the air,
how about installing a ball valve right at the oil cooler which would direct
all, some, or none of the oil either through the cooler or divert back into
the return line. This valve would be controlled from the cockpit via a
cable.
Just like the valves that control the hot water that flows to the heater
cores of our millions of automobiles. Same principle, different objective.
Boy, ya gotta love the experimental category.

Way to messy....don't go there. Block up the gap with some foam/paper/tape
then use modeling clay to get your shape. After you get the shape your
looking for wax any exposed metal taping off all other area's, then lay up
your glass. Don't let the clay dry out, and wait for the glass to cure before
you remove it from your plane then trim. That's how I did mine and it came
out nice.

Subject: | Balanced wheel pants benefits and How to land this thing! |
From: | Rick_Smith(at)tivoli.com |
02/19/2001 02:53:31 PM
My 180 hp. RV-6 (N1150S) has 215 hours on it now and it has been quite an
enjoyable learning experience.
Concerning gear leg shimmy and balancing wheel pants there are a couple
observations I can relate.
Some gear legs shimmy fore and aft while taxing and some don't. If I have
greater than 30 psi in the tires they shimmy all the time while taxiing
with or without wheel pants. At 25 psi shimmy very rarely occurs and it is
much easier to land. A wooden stiffener bonded to the gear leg may prevent
the symptom but it appears the causative factors are brake disks that are
not perfectly true and hard tires on smooth pavement.
Balancing the wheel pants for and aft so the CG is at the axle does a
couple neat things. One is it prevents a torque load from being applied to
the mounting points when the wheel gets deflected vertically by a bump. If
you operate out of rough hard fields you will notice that the mounting
attachments get torn up and the pant mounting develops play allowing the
pants to tilt up and down. Theoretically, balancing may also cause them to
be directionally stable in flight just like an airfoil which may reduce
drag some minuscule amount. My second set of pants are not balanced and I
have not experienced shimmy and since they fit so close to the wheel
(quarter inch gap all around the tire) I don't go into dirt strips anymore
but it sure is fast.
Now for a question I have been struggling with.
How do you wheel land a RV-6 taildragger. My normal attempt scenario is to
approach at about 85 with half flaps, level off as close to the runway as
possible and try to kiss the runway with the tires and relieve back
pressure or try to feed in forward stick to plant it. Hasn't worked yet!..
As soon as the wheels touch it bounces into the air before you can feed in
forward stick to suppress it. Should I just feed in forward stick while
holding off and fly it into the concrete while saying "damn the decent
rate, I wanna wheel land"?
Last week I flew in a F1 Rocket with Titanium gear legs and it soaks up the
decent rate like oleos and wheel lands perfectly. Feels like you couldn't
bounce it if you tried. Apparently the Sonex guys also use titanium gear
legs and they also claim similar rebound dampening performance.
If that is really what I am experiencing my next venture may be building a
set of RV-6 titanium gear legs.
The gear legs on the F1 are not bent but use a welded axle fitting that
lets you adjust the wheel alignment with shims. Very clever.
Sorry for the long post but not being able to land my own plane is getting
embarrassing.
Regards,
Rick

Rick,
Well you know, maybe it's like the old joke. "Doc, it hurts when I do
this." Doc says; "don't do that."
You will get many opinions but mine is that it is never NECESSAY to wheel
land an RV. That includes a 20 knot gusty direct crosswind. That being
said I understand why one would want to be able to do it. I can do it five
times in a row perfectly and the next one will completely humble me. Mostly
I don't try it anymore. I think the only trick is that the descent rate
must be very low or you will be relaunched halfway into orbit.
There is nothing more impressive to a passenger than a really well executed
one but the potential for complete humiliation is far too great. My only go
around to date was with a new passenger and a botched wheely.

Subject: | Help! RV-4 Fuse Bulkhead Line Up Problem |
OK, I have a problem and can't figure it out. I was wondering if anyone else
had this problem.
On my RV-4 Fuse, the .125 AL angle on F413 does not line up with the .063
angle on F404. These AL angle should meet approx. 90 degrees and have one
rivet attaching them. They are about 1/4 off or so and thus I cannot get a
rivet between them. I have the F413 aligned with the bottom of the firewall
and the bottom of F404, but the top side appears to be 1/4 too tall thus not
permitting the AL angles to line up.
I am having the same problem on the back side, the AL angle on the F415 does
not line up well with the .063 angle on the back of F404. Again the F415 is
lined up on the bottom of F404 and F407, but it too appears too tall as the
AL angle on F415 is higher than the attaching angle on the back of F404.
I assume that is a very important rivet as it ties the heavy AL angle from
the firewall to the wingspar and then back to F407. Is it safe to just rivet
the rest of the rib bulkheads but not the AL angles together? Any
help/advice would be greatly appreciated. Thanks

From: | Robert McCallum <robert.mccallum2(at)sympatico.ca> |
Subject: | Re: Lycoming on Vernitherms |
It actually does make sense. If you've followed this l-o-n-g thread it has been
explained that there
two parallel paths for the oil to follow. One path is through the cooler and filter,
the other is
via a bypass passage the size of which is controlled by the vernatherm (sp?) valve.
Hence the
minimum or low oil temps are controlled by the airframe i.e. how much cold air
passes over the
cooler etc. and the maximum temp is (hopefully) kept in check by the vernatherm
(sp?) whose function
causes ALL of the oil flow to be through the cooler when the temps get up to it's
set point. Thus at
lower oil temps the vernatherm is wide open and the oil has two paths to follow.
Hopefully enough
bypasses the cooler for the temperature to rise to acceptable levels. If not then
reducing cooler
efficiency by blocking airflow comes into play to help raise temps. Thus the "winterizing
plate"
installed on most aircraft in the north where we get WINTER. At higher oil temperatures
the
vernatherm gradually, as the temp rises, reduces those choices of flow path to
one. Namely through
the cooler thus hopefully keeping a fixed ceiling on what temperature the oil can
attain by forcing
all of it to be cooled.

Can't help you with the first question but as for the MP, I made up some

I used that although you can get 1/8" as well I believe (from Aircraft

close (depending on the thickness of the f-glass in that area). I used a
bench mounted disk sander to sand down the mounting surface on the
receptacle by 1/32" or so before riveting on; problem solved.

Same problem here too, but I didn't want to grind down the inside like
Randall because the interior of my cowling is PAINTED so I went with the -4s
also. Randall's paint job might look better on the outside than mine (he has
a gorgeous Craig Roberts clearcoat job), but mine looks better on the
inside. ;-)

Subject: | vibrations (floor stiffeners) |
I installed these brackets a couple weeks ago... I did all 4 stiffeners even
though only the outboards show on the plans. In discussing this with my
local RV bunch we finally snapped to the fact that Van's standard center
console ties the inboard stiffeners to the spar. If you leave out the
console as I did, then add the brackets to the inboard stiffeners. They make
a noticeable difference in oil canning. I crawled underneath before
installing the brackets and got a fair amount of flex & oil canning when I
pressed up on the skin. After installation, it's almost non-existent. Plus,
it's gotta help withstand my 10+ bubba factor.
