Deems,
Have the modifications fixed the issue with your mount? I would like
to know before I call and discuss the mount for my engine. I take
exception with the SB. First of all I paid a crap load of money for a
Lycoming and my Barrett engine is NOT a clone. Second of all, Lycoming
offers a cold air induction sump also and I'm betting that that "stock"
Lycoming part is also going to see interference.
If they know what the problem is and know how to fix it without
impacting everyone else, they should. I agree that they do not need to
accommodate every variation out there but this is a fairly common mod
and I'm not doing it to hot rod anything. I have a HP limiting device
called a throttle and the additional HP I may see is to get me out of
short strips or high density altitude locations, not to get me there 10
minutes sooner. I really wish Van's would get the difference already
and move on with the stupid hot rodding crap.

Wow Deems. Thanks for passing this along. There are a few points that
should be understood by individuals who are either new to the list or
are still in the homework phase of engine selection. Primarily, the
Barrett Precision Engines IO-540-X is not a "clone" engine. It is made
of all new Lycoming components sold from Lycoming to us as part of their
kit program. The only exception is the cold air induction sump, plenum
and pipes which Monty designed almost 20 years ago for use in the
experimental arena. In some cases, the compression ratio is increased
at the request of the airplane builder using propriety pistons. Oops,
and we use silicone rocker box gaskets made by Superior. Other than
that, all OEM certified parts are used on the 540. Of course the
IO-540-X is also available with the stock sump.
There is a clearance issue with the mount. I do have a local source for
the modification needed on the mount and am happy to pass that along to
anyone who is interested or intends to use the modified IO-540-X with
cold air induction. This individual has modified the RV-10 engine mount
with the standard sump. We are meeting with him over the next few days,
and we will provide the engine mount modification to you as a value
added service with your engine at no additional charge.
For those of you who have already taken delivery of your engine equipped
with Barrett Cold Air, please contact Rhonda for assistance in getting
your mounts modified.
Re: Van's advisement about going with standard hp, this is a debate for
you as builders, and each individual has different needs and wants. We
have always recommended moderation in increasing the hp. Van's has an
interest in selling you a stock Lycoming engine. I doubt very seriously
that he is selling them to you at cost!
Thank for your continued support.

page forward and you can see several other shots. I think this must be a

For a quick explanation of control surfaces see this:
http://www.centennialofflight.gov/essay/Theories_of_Flight/control/TH28.htm
Those tabs forward of the hinge line out on the tips of the elevator
aren't there just to provide a convenient place to store the mass
balance lead. 172's have leading edge elevator tabs out at the tip.
Obviously, Cessna relies on aerodynamic balance rather than mass
balance and probably a lower Vne to limit flutter. My old AA1A had a
spring balance system on the elevator which centered the elevator to
the trim tab setting along with moving tips that provided a certain
level of aero balance and hid lead for mass balance resulting in VERY
light loads (compared to C150's).

I do not see the words "hot rodding" in the SB nor do I see anything but
Vans covering their buts. It looks pretty simple, the motor mount is only
guaranteed to work with the stock IO-540 without cold air induction, if you
go with any other variation, it is on the builder to fix the motor mount.
Also their statement about higher horse power does not limit you on the size
of engine you are putting in, just that you must account for it in your
operating limits in order to meet the intent of the statement in the SB.
There are many airplanes with de-rated turbines.
Yes I have a stock IO-540....so this really doesn't affect me. But, I hate
to see this mud slinging at Vans on something that they are reasonably
handling.....now about the fiberglass parts.........

I'd say we are separated by a common language. I don't consider the
balance horns on Cessna "tabs" any more than they are on the hundreds
of other aircraft that have them. I consider "tabs" as small strips of
metal riveted to the rear of a control surface. What you describe is
most commonly called a horn or counter balance, not a tab.
>From your reference link "Tabs are auxiliary control surfaces placed
at the trailing edges of the primary control surfaces."
Which is why I wrote what I did.

Subject: | Van's Motor Mount SB Ranting |
Allen, thank you for clarifying what should have been obvious to most
builders. Your engine is not a "clone". That statement presents the
voracity of contempt held at VANS to those renegade builders who have
the audacity to improve on a design.
Seems that was exactly how VAN started his business with an improvement
to someone else's design a few years ago which began this process of
model improvement. I have posed to Jon Delamarter that he might respond
on the Thunderbolt "Clone" products as well. Next we will hear that
unless you buy a new engine direct from VAN, then the mount will not
work. That you will fall out of the sky with a Lycoming Thunderbolt.
Or, we will again hear how flutter and speed are bringing down the
fleet. Another reason to check those lead counter-weights against the
written standard - additional weight with those clones engines.
Deems - thanks for the prompt response. Scott - thanks for doing the
right thing for Deems. Now to get the welder to do them right in the
first place. Tim, you must be running a clone as well, since it wasn't
and still isn't a Barrett and you seem to have done the unthinkable by
modification to the correct mount.

Subject: | Van's Motor Mount SB |
Reasonably handling to me would suggest they make the change to their
production run eliminating this problem with 99% of the engines used.
Tim had a "stock" setup and still had this problem as did others.
I think the final statement in the SB describes their position on the
unofficial term of "hot rodding" so let's cut the semantics. I also
didn't say anything about them covering their butts. The SB went out of
its way to suggest that the Barrett engine is not a stock Lycoming which
is absolutely incorrect. Frankly if I was Alan I would be rather
irritated and would be having a conversation with Van's about that
incorrect fact and suggest they change the wording. The SB also
suggests that if you use Lycoming parts this won't be a problem which
has already been shown as incorrect.
I talked to Scott and Van's position is he is afraid of giving the
appearance of authorizing these changes for litigious reasons as he
tested the aircraft with the 260HP engine. This is the ONLY reason they
don't make the change across the board. As I told Scott, the addition
of the cold air sump for me was for a safety margin getting out of grass
strips (my home airport) and high density altitude locations. When I
purchased my engine I was living in Texas where it routinely is over 100
degrees. I can tell you that the cold air sump probably isn't going to
get me back up to 260HP by itself when it's over 100 in the high desert.
Same with Deems. While Van is in CYA mode against increased HP, Van is
also setting himself up for lawsuits in the other direction by impacting
safety. If he had the chance to make a non-impacting change to his
design to improve safety and didn't do it, it's no better than
encouraging wild modifications. Scott is checking with Van on if he can
drop ship the mount directly to Alan for modification but he's afraid
that they may also give the same impression. Give me a break. How
about if I sign a legal release of responsibility like I had to when I
deleted items from the finish kit. Or better yet I can give him Alan's
home address as mine. Or they can take the don't ask, don't tell
approach. This is just silly.
I'm not slinging mud at Van's, I'm simply stating that if they have a
solution they should implement it. That's called customer service and
improving a product. Unfortunately they have a long history of ignoring
customer suggestions and going on their merry way (fiberglass, shipping,
etc). They make a great aircraft kit but there is no way to hide from
lawsuits nowadays. It makes me sick that people cannot assume
responsibility for their own actions anymore to the point that everyone
is doing lawsuit mitigation as the first step in anything.
I bought an engine from Barrett and at least I know they will take
care of any issues that arise and not run and stick their head in the
sand.

Reasonably handling to me would suggest they make the change to their

Tim had a "stock" setup and still had this problem as did others.
I think the final statement in the SB describes their position on the

didn't say anything about them covering their butts. The SB went out of
its way to suggest that the Barrett engine is not a stock Lycoming which
is absolutely incorrect. Frankly if I was Alan I would be rather
irritated and would be having a conversation with Van's about that
incorrect fact and suggest they change the wording. The SB also
suggests that if you use Lycoming parts this won't be a problem which
has already been shown as incorrect.
I talked to Scott and Van's position is he is afraid of giving the
appearance of authorizing these changes for litigious reasons as he
tested the aircraft with the 260HP engine. This is the ONLY reason they
don't make the change across the board. As I told Scott, the addition
of the cold air sump for me was for a safety margin getting out of grass
strips (my home airport) and high density altitude locations. When I
purchased my engine I was living in Texas where it routinely is over 100
degrees. I can tell you that the cold air sump probably isn't going to
get me back up to 260HP by itself when it's over 100 in the high desert.
Same with Deems. While Van is in CYA mode against increased HP, Van is
also setting himself up for lawsuits in the other direction by impacting
safety. If he had the chance to make a non-impacting change to his
design to improve safety and didn't do it, it's no better than
encouraging wild modifications. Scott is checking with Van on if he can
drop ship the mount directly to Alan for modification but he's afraid
that they may also give the same impression. Give me a break. How
about if I sign a legal release of responsibility like I had to when I
deleted items from the finish kit. Or better yet I can give him Alan's
home address as mine. Or they can take the don't ask, don't tell
approach. This is just silly.
I'm not slinging mud at Van's, I'm simply stating that if they have a
solution they should implement it. That's called customer service and
improving a product. Unfortunately they have a long history of ignoring
customer suggestions and going on their merry way (fiberglass, shipping,
etc). They make a great aircraft kit but there is no way to hide from
lawsuits nowadays. It makes me sick that people cannot assume
responsibility for their own actions anymore to the point that everyone
is doing lawsuit mitigation as the first step in anything.
I bought an engine from Barrett and at least I know they will take
care of any issues that arise and not run and stick their head in the

I do not see the words "hot rodding" in the SB nor do I see anything but
Vans covering their buts. It looks pretty simple, the motor mount is
only
guaranteed to work with the stock IO-540 without cold air induction, if
you
go with any other variation, it is on the builder to fix the motor
mount.
Also their statement about higher horse power does not limit you on the
size
of engine you are putting in, just that you must account for it in your
operating limits in order to meet the intent of the statement in the SB.
There are many airplanes with de-rated turbines.
Yes I have a stock IO-540....so this really doesn't affect me. But, I
hate
to see this mud slinging at Vans on something that they are reasonably
handling.....now about the fiberglass parts.........

Subject: | Re: Van's Motor Mount SB Ranting |
I don't want to ruffle anyones feathers here, but here is a different point
of view.=0A=0AI had talked to Van's regarding the certified engines about
1 to 1.5 years ago. They did not try to just sell me a certified engine.
In fact they told me that the I was better off getting an experimental engi
ne from one of the engine builders. So my experience with Van's makes me b
elieve that they are not out to just sell an engine; and of course they mak
e money selling engines. The RV10's, RV9, RV7s and RV8 are selling well an
d I am sure Van is doing very well financially. Now a few crashes of RV10
due to supposedly structural problems could slow his sales down in a hurry
so I think his viewpoint is based more on safety then selling engines.=0A
=0AAs far as hot rodding, there is definitely an actual amount of power abo
ve which one might get in trouble if they don't modify the structure to ha
ndle it. Is that 260hp 300hp or 400hp it appears no one knows. Van's clai
ms that it can handle 260 hp but they don't want to stick their neck out an
y further and I don't blame them for that. The 260hp number is what their
design and testing is based on. Is there some margin? Probably, if not th
ey cut it too close. =0A=0AIf its okay to go to 280hp is it okay to go to
300hp or 350hp how about 500hp? Where is the cutoff? Should the person go
ing to 300hp have to do some homework to ensure that the aircraft will be s
afe with that much power? If the plane does come apart and people get kill
ed than was he not negligent ? I can see having to defend this in court, "
Are you a structural or aeronautical engineer? No. Have you designed any a
ircraft or have experience designing aircraft? No. Well then if the design
er of the aircraft thought that it was not capable of handling more than 26
0 hp, and repeatedly said so, what made you think that you knew better?" a
nd no I am not a lawyer. The bottom line to this is if you are going to mo
dify it and fly it outside the envelope that Van's has designed it for than
you need to do the analysis and/or testing to verify that its safe in the
expanded envelope.=0A=0ALets go back to the fatigue discussions we had seve
ral times on this list. If there was a fatigue critical item in the engine
compartment (i.e. engine mounts, engine mount support fittings aft of the
firewall that are ending up with short edge distance in a lot of aircraft,
etc) then going to 286 hp (10% increase) would halve the life of these item
s and at 315 hp you would have approximately only 1/4 of the life left. And
maybe you allready ate away at half the life because your edge distances w
ere to small. Now for someone going to 315 hp are you sure that those item
s are not critical?=0A=0ANiko=0A=0A=0A----- Original Message ----=0AFrom: J

Subject: | Van's Motor Mount SB |
I probably shouldn't weigh in on this, simply because I usually don't have a
clue. However, after reading the notice and knowing a bit about business,
it appears Vans is simply narrowing their scope of liability. It'll not
hurt their business one whit to do so and might hurt to go the other way.
They will continue to sell and support the narrow band of known product, and
they will make a good living doing that. They will let Marty and others
deal with the issues that lay outside that band. And, that's okay. There
is good innovation happening all around Vans and they are fine with that. I
daresay they are happy with that. The cottage industry that has grown up
around their product is quite large and strong and will continue to grow and
improve. Should they make improvements to, say, the fiberglassed parts,
sure and yes and I agree. If they have a stock part that is not of high
quality in fabrication, damn right they should improve that. Should they
modify the engine mount to make sure it works for a "standard" engine, of
course. They are all about keeping well within a safety and knowledge zone.
Let the market improve the product. They will still make their money.
Now, having said that, I do agree that the language found in the SB was not
well thought out. Clearly Barrett's engines are not aggressively modified
clones, and clearly they didn't even have the mount correct for Tim's
engine, so to put their stake at this point in the sand doesn't make sense
on the face of it. And certainly building demonstrators as minimal VFR
machines was a silly thing to do. Clearly the RV-10 is a cruising IFR
machine, and should be treated as such. It has always been an attempt by
the company to narrow the liability and cost options. But, the stake has
been put in the sand and we will continue to build the planes, modify them
as the market allows, and continue to enjoy the hell out of them.
My conclusion? We all have our quirks. We meaning both individuals and
companies. But the cool thing in this society is that we have a market that
can fill the voids and make things even better. I have a feeling Van's will
be seeing many a gear, many a cabin, many a cowl being returned, and many an
engine not sold, as people find better alternatives. Hopefully this will
make an impression on them, but if not, hey, we'll find a way to move
forward with their basic product, which ain't bad.

I do not see the words "hot rodding" in the SB nor do I see anything but
Vans covering their buts. It looks pretty simple, the motor mount is only
guaranteed to work with the stock IO-540 without cold air induction, if you
go with any other variation, it is on the builder to fix the motor mount.
Also their statement about higher horse power does not limit you on the size
of engine you are putting in, just that you must account for it in your
operating limits in order to meet the intent of the statement in the SB.
There are many airplanes with de-rated turbines.
Yes I have a stock IO-540....so this really doesn't affect me. But, I hate
to see this mud slinging at Vans on something that they are reasonably
handling.....now about the fiberglass parts.........

Deems,
Have the modifications fixed the issue with your mount? I would like to
know before I call and discuss the mount for my engine. I take exception
with the SB. First of all I paid a crap load of money for a Lycoming and my
Barrett engine is NOT a clone. Second of all, Lycoming offers a cold air
induction sump also and I'm betting that that "stock"
Lycoming part is also going to see interference.
If they know what the problem is and know how to fix it without impacting
everyone else, they should. I agree that they do not need to accommodate
every variation out there but this is a fairly common mod and I'm not doing
it to hot rod anything. I have a HP limiting device called a throttle and
the additional HP I may see is to get me out of short strips or high density
altitude locations, not to get me there 10 minutes sooner. I really wish
Van's would get the difference already and move on with the stupid hot
rodding crap.

If I am not mistaken, I believe that the core issue at the heart of this discussion
really extends beyond liability concerns.
But first, let me back up Allen's statement regarding a "clone" Lycoming from BPA.
A clone, in my opinion, would refer to a Superior or ECI engine. The folks
at Barrett assemble their engines from a box of Lycoming parts that they buy
from us, Lycoming. In other words, the majority of their parts come from the
same parts bin as a certified or Thunderbolt Lycoming. As with all of our kit
shops, they have the discretion to modify the parts or add parts that in their
judgment are safe and suitable. Michael and a lot of other folks have bought
engines from BPA based on a well deserved industry reputation.
Having said all that, I think it is just possible that the Van's SB specifically
mentioned Monty's custom sump/intake system due to the fact that, to date, this
is really the only commonly used aftermarket system of it's type (Tip of the
hat to my good friend Kevin Murray at SkyDynamics; Kevin's system uses a stock
Lycoming sump and is not exactly an equivalent.) Monty led the way in the
experimental aftermarket with his system long before the RV-10 was on Van's drawing
boards. And yes, to Michael's point, the cold-air system we are developing
in Thunderbolt is similiar enough that I expect that the same interference
would occur. (I must take a technical exception to one of your points, though
Michael; a Barrett engine is not a stock Lycoming engine by definition. Neither
is any engine that we build here in Thunderbolt. That's not a bad thing!
It just means that those of us in the custom experimental engine market have
an opportunity to do things a little differently.)
To Van's point, I understand their reticence to implicitly or tacitly endorse modifications
of their design. Once that is allowed to begin, where does it end?
The line simply must be drawn somewhere. We cannot in good conscience ask
an engineer to design in a safety margin and then endorse our intention to disregard
that margin. Again, to Michael's point, throttle/manifold pressure management
is a legitimate method for limiting horsepower.
Now to the core issue I mentioned at the beginning. Those of us who participate
in the experimental aircraft market do so knowing full well that the law supports
the individual builder's right to modify the end product at will. Participation
at any level is therefore risk inherent. Therefore, as a member of this
group, I would ask that you would be patient with our attempts to balance
innovation and performance with safety and reasonable risk.

Subject: | Re: Vans motor mount SB |
Fred,
I think ultimately you can get a "hotrodded" RV approved. It would
depend on how comfortable and familiar the FAA DAR or Inspector is
with the modification, the original design, and the level the
modification deviates from the original. As an experimental aircraft,
if you can figure how to install one or two turbine powerplants to an
RV-10, you are free to do so (an extreme example I know). The key will
be how many hoops your FAA rep will make you go through to "prove"
your ship is airworthy. One of the good things about buying a kit from
Van's you get the design and engineering work they put into the
original airframe as a basis for your ship and if yours is within the
design limits studied by Van's, then I think you have an easier time
with your paperwork. The further away from a "standard" RV-10 you go,
don't be surprized that the FAA reps will want to see some engineering
analysis to support the re-design and don't look to Van's to support
you either partly due to the "cover my ass" syndrome.
There's a couple points that should be considered why Van's has a
"CMA" attitude towards "major" modifications: 1) They spent a lot of
time and money developing an airframe that conforms to a certain set
of criteria. Van's could incur considerable expense studying each
deviation request coming in from the builder community. The results
could drastically affect one or more aspect of the original design,
which in Van's opinion could be detrimental to the overall utility of
the airframe. 2) As kit airplanes become an increasing percentage of
the overall GA fleet, especially those aircraft 18 years and newer,
it's increasingly likely that some ambulance chaser is salivating at
the chance to go after a kit manufacturer. A modification that greatly
degraded some part of the performance criteria of the airframe
originally set by Van's and was supported by analysis by Van's could
be blood in the water to the legal sharks should that aircraft crash.
For now, the 51% rule shields Van's, and that theuy probably don't
have the corporate deep pockets like Cessna or Beechcraft, but other
support services may not see such protection.
Does anyone know if Van's faced a threat of lawsuit from the
Arlington crash mentioned in a previous post? If it wasn't then, I
feel sooner or later a kit maker will see a liability suit as a result
of a crash. I think liability concerns may affect all kit makers and
could kill the industry as it helped depress the production industry
way back when. Hopefully this won't happen until after I begin work on
my own airplane.
Bottom-line is I see valid reasons for Van's position to
modifications beyond the original design criteria of its airframes.
And on the otherhand, I support those experimenters who want
improvements for their own personal birds, it is EXPERIMENTING
afterall. But, don't go whining when the Feds want you to support your
modifications with rational analysis and Van's tells you you're on
your own.

That is what I call customer service. Barrett just earn a point for my
decision on the engine. It's the small things that help me make the big
decisions.
Maybe we all need to send something to Van's and have them publish a
concrete reason for releasing something that surely has nothing to do with
Safety. I may be wrong on this but when I see a Service Bulletin I take it
to mean- improvement found that will make the part, or other safer. A more
powerful engine may get me to go slightly faster but just how much faster
than the 201MPH advertised.. no power means I get over the mountains sooner,
it means I have it if I want it. Vic, as an example has more power and he
has said more than once he rarely uses more than 75% on his plane.. but he
has it if he needs it. I see adding 20-30hp as a good thing and Van's using
a SB so people like Deems don't have their welder do extra work by re
welding to fit anything different than a stock engine, versus Van's just
working with Mattituck, Thunderbolt, Barrett and any other engine company
out there driving their kits to work out a motor mount that fits them all-
ie make the mount fit the largest sump out there without safety issues. It's
been done for Tim, Deems and probably many more out there. It's experimental
and it HAS been tested so just weld a different motor mount and skip the SB.
I am still clueless to the motor mount but the point is I have seen two
perspectives here. 1) we'll take care of the motor mounts as part of the
engine price and 2) We won't modify nor support you if you don't use a stock
engine.
if it wasn't for #2 making the kit I would consider taking my business
elsewhere, but I think back to why did Van's publish a SB? I really would
like an explanantion for the logic with proof to back it up. More is not
worse unless we were talking out of C/G weights or a turbine engine.. than I
would understand..

Subject: | Van's Motor Mount SB Ranting |
In reality the 260HP number means next to nothing. The real limiting
factors are in the size and weight of the engine, any changes that it
causes to the CG, possible torque increases on the mount, and most
importantly VNE. Van's is stating that they believe that there is no
chance to exceed their design limitations in normal flight with an
engine rated at 260HP. I say rated because it is impossible to say if a
engine is putting out more or less HP unless someone builds reference
data for that engine using a known measurement like a dyno.
So that being said, if someone limits an engine of any size to the
same characteristics they are not exceeding the design specifications.
In the case of a larger engine, anyone can mitigate weight issues by
doing a weight and balance. In my case the sump is lighter than the
stock component. Torque, well that can be a bit of a guess as I'm
betting Van never did any destructive testing on their mounts so they
have no idea if there is a flaw in even the current version that could
rear its ugly head down the road. But then again there is a fair amount
of data at this point on the "stock" 540 in an RV-10 for us to take a
good guess that there isn't a problem. Most of us that are making
improvements to the engine are doing it to the exact same 260HP Lycoming
IO-540 that is considered acceptable so let's just assume the mount is
perfectly fine for this application. That leaves us with the VNE issue.
There are plenty of ways to exceed VNE with a stock 260HP engine. If
you cross the manufactures set VNE limit you have moved into the test
pilot realm and you are on your own. Hopefully you know what you are
doing. If the modifications to my engine put me over 300HP (they
didn't) it makes absolutely no difference to the aircraft as long as the
other parameters are kept in check. Easiest way to do that is by
connecting your eyes watching your airspeed with the hand controlling
the throttle.
So my point is I don't feel it's an actual amount of power expressed
in HP that is the issue as that really has no direct bearing on if you
will fall out of the sky. So if that number is really irrelevant as
long as you keep things inside the design boundaries, who cares what the
actual HP number is? Operating limits are valid numbers and also
something Van should absolutely stand behind but I would rather see
those than just saying arbitrarily that anything over 260HP is going to
be a problem.
It's Van's choice on whether or not to accommodate the builders out
there and Barrett's cold air induction is a popular option. As I told
Scott, I understand their decision even if I don't agree with it. Allen
immediately had a solution to the problem so I'm not concerned. You can
also bet that Thunderbolt is going to be pushing their cold air
induction from Lycoming and they will see the same problem. Will Van's
have the same stance on the subject even though it is a direct Lycoming
option? Maybe Van's will silently change the mount design under the
guise of optimization once this subject dies out a bit so they can say
they didn't do it for the hot rodders out there. Time will tell. In
the mean time Scott has agreed to drop ship my mount directly to Barrett
for his local man to modify. I'm glad to see they are willing to work
to a compromise with some of us on this. If anyone else is ordering an
engine with cold air, make sure you add this request to the finish kit
order. Once I have it back I'll be happy to post pictures. Interesting
thing is that I've been told the first several kits didn't even have the
troublesome cross member in the engine mount and haven't been replaced.

I don't want to ruffle anyones feathers here, but here is a different
point of view.
I had talked to Van's regarding the certified engines about 1 to 1.5
years ago. They did not try to just sell me a certified engine. In
fact they told me that the I was better off getting an experimental
engine from one of the engine builders. So my experience with Van's
makes me believe that they are not out to just sell an engine; and of
course they make money selling engines. The RV10's, RV9, RV7s and RV8
are selling well and I am sure Van is doing very well financially. Now
a few crashes of RV10 due to supposedly structural problems could slow
his sales down in a hurry so I think his viewpoint is based more on
safety then selling engines.
As far as hot rodding, there is definitely an actual amount of power
above which one might get in trouble if they don't modify the structure
to handle it. Is that 260hp 300hp or 400hp it appears no one knows.
Van's claims that it can handle 260 hp but they don't want to stick
their neck out any further and I don't blame them for that. The 260hp
number is what their design and testing is based on. Is there some
margin? Probably, if not they cut it too close.
If its okay to go to 280hp is it okay to go to 300hp or 350hp how about
500hp? Where is the cutoff? Should the person going to 300hp have to
do some homework to ensure that the aircraft will be safe with that much
power? If the plane does come apart and people get killed than was he
not negligent ? I can see having to defend this in court, "Are you a
structural or aeronautical engineer? No. Have you designed any aircraft
or have experience designing aircraft? No. Well then if the designer of
the aircraft thought that it was not capable of handling more than 260
hp, and repeatedly said so, what made you think that you knew better?"
and no I am not a lawyer. The bottom line to this is if you are going
to modify it and fly it outside the envelope that Van's has designed it
for than you need to do the analysis and/or testing to verify that its
safe in the expanded envelope.
Lets go back to the fatigue discussions we had several times on this
list. If there was a fatigue critical item in the engine compartment
(i.e. engine mounts, engine mount support fittings aft of the firewall
that are ending up with short edge distance in a lot of aircraft, etc)
then going to 286 hp (10% increase) would halve the life of these items
and at 315 hp you would have approximately only 1/4 of the life left.
And maybe you allready ate away at half the life because your edge
distances were to small. Now for someone going to 315 hp are you sure
that those items are not critical?

The short version is Van's was hit with a lawsuit around similar items
in the past. They made modifications to the RV-10 mount in the past
because their mockup was wrong. When they realized that Deems issue was
because of the cold air sump, and others were in the pipeline, they kept
their word to Deems and then issued the SB stopping any future
modifications. Good thing Tim didn't let them know he had a Lightspeed
ignition on his when he sent it back for modification, might be
producing more than 260HP.

Should I keep the nitrous system secret still, or can I tell
people about it now. ;)
It's too bad we had to see this whole clearance thread even
come BACK with the prior history we had. One fix done well
could have prevented a reoccurance.
I still get a laugh out of one person saying that my engine
wasn't a Lycoming engine, so maybe mine was different....it
wasn't a Lycoming, it was an Aerosport. That always gives
me the giggles. That's like saying, I don't drive any GM
products....mine's made by Chevrolet.

I have a question about what size/type of bolts to use for mounting the

On the subject of engines, my reqts are pretty basic - standard IO540
D4A5 with one Mag replaced with a lightspeed plasma III.
Ignoring the Lightspeed, what is the difference between buying a Vans
Experimental 540 at $39,900 vs say an Aerosportpower at $40,300? $400
is not a lot, but what added value do the engine (re-)builders give
beyond the standard engine provided by Vans?

James :
Thanks for your thoughtful reply. All of those issues were running
through my thoughts. I understand Van's point of view and legal
responsibilties. I am a gynecologist and well aware of the legal
ramifications of something done "outside of the standard of care."
After having talked with Mr Barrett at Oshgosh last year I am leaning
toward having him build me an engine. I see a lot of benefits in his
designs. The changes make sense. But again, not being an engineer and
being truely able to back up with documentation any significant
powerplant changes, I do not want to invest 150K on this airplane and
have a paperwork fight to get it certified.
I have followed the posts and know that if I put a "stock" Lycoming in
my 10 I will have a great airplane that will last me for 20 years.
I appreciate all of the input from the previous builders. It's
discussion of these issues that move things forward and make it safer
for all of us. We better know the questions to ask.
I just read the last couple of posts before I sent this reply. All this
is because of Deems pushing the wrong button? :) He sure knows how
to stir the pot.

Anybody seen torque values for the front wheel halves? It's an AN4 bolt, so
50-70 plus drag should be correct. Just wondering if there are other

Subject: | Canada first Flight with James Cowl |
This is a post of an offline note I got from Barry Martin
regarding David Corrigan's airplane and first flight in
Canada. The photos were sent inline, but I'll attach them
below. Not in order, in case the forum strips more than
a certain number.
Tim
-------
The first Vans RV-10 to fly in Canada took to the air on January 18,
2007 from the Charlottetown Airport on PEI. After approximately 16
months of building and, much to the delight of owner and co-builder
David Corrigan and co-builder Deryck Hickox, the RV-10 lifted off around
noon in clear skies and light winds, although the temperature was a
little cool, being around minus 5 degrees C. With the IO-540 purring
like a kitten, the RV-10 was through circuit height before reaching the
end of the runway.
Test pilot Glen McLarty took the RV to 4000 feet over the airport to do
the initial tests then headed north of the airport to finish the first
round of tests. In communication with the ground crew, Glen relayed that
the plane flew straight and level even with his hands off the stick.
The RV-10 is equipped with a Lycoming IO-540 that was rebuilt by Aerotec
in Halifax and has a MT 3 blade propeller up front. The aluminum portion
of the kit was of top quality. Since this was a quick build kit the
cockpit area and most of the wings were riveted together in the
Philippines while everything aft of the cockpit was riveted in
Charlottetown by Deryck, with bucking help from Dave, Terry Cooper and
me. When both pieces were fitted, not a hole was out of place. The
instrument panel was prefabricated by Gulf Coast Avionics in Florida and
I did the wiring and hooked up the panel. The panel had a few bugs in it
but most were found before the panel was installed. The panel is well
equipped with an AF-2500 engine monitor, Garmin 430, Garmin SL-30, PS
Engineering Audio Panel, Garmin GTX 327 Transponder, ATD-300 Traffic
Watch and a TruTrak Autopilot. As all the instruments are electrically
run, there is also a back-up battery.
This is the first homebuilt project for Dave, locally known as The
Flying Real Estate Agent, but Deryck has over 30 years experience
building and restoring aircraft, much of it with the Canadian Warplane
Heritage in Hamilton. Deryck, originally from PEI, moved back after
retiring from Air Canada where he worked as an AME. Since starting the
project, Deryck has formed D. Hickox Aviation Services specializing in
aircraft restoration, fabric covering and home built aircraft. He can be
contacted at xxx-xxx-xxxx (trimmed for privacy) if you have a project
you would like him to build.
Dave is hoping to have the 25 hours flown off before Sun n Fun this
April. If you make it to Sun n Fun and see this beautiful RV-10 sitting
there with the registration of C-FYYG, you will know that he was successful.

John,
Thanks. I have added Vic Syracuses rudder trim so I am going to need to balance
the rudder. So I guess what I need to do is after it is finished, I need to
lay the VS and attached Rudder on their side. Then add a 30.8" rod to the top
with a 1 lb weight. Should the rudder/VS lay flat or should the trailing edge
of the rudder droop? The 30.8" would be measured at a 90 deg angle from the
pivit point line.
Is this correct?
Gary

Subject: | Cold Air Induction |
Yes, yes, and yes. :-) The cold air induction basically removes the
intake tubes from the oil sump (stock configuration) which heat soaks
the incoming air. Hot air is less dense which means less HP. Barrett's
sump is also magnesium which is lighter than the stock sump. As for the
holy cowl, you need to go with the James cowl anyway which is made for
the cold air unless you want to do a bunch of work on the stock cowl ala
Gary Specketer. Figure on the credit for the stock cowl being around
$800 by the time you subtract the various parts.
Net impact, unknown at this time. The first couple of this
combination are still coming out of the gate. I believe the cowl on
something like an RV-4 gains you about 10 mph and the cold air induction
is good for around 10 ponies.

Subject: | Re: Cold Air Induction |
Standard Lycoming induction has the induction air routed through the oil
sump, the result is that the air intake to the cylinders is heated by
the surrounding oil in the sump. Cold Air Induction takes ram air and
routes it directly to each cylinders intake bypassing the oil sump. this
requires a custom oil sump and hence the recent discussion. If you
remember your pilot training, Cold air is more dense and produces a
stronger air charge going into the cylinder, which results in more
manifold pressure and more power (OOPS there I go again hot rodding!).
Its kind of like putting a booster on your engine without adding any
moving parts. Free power (well almost free) !. The answer as to does it
add horsepower depends on who's asking, but I'm VERY happy with the
results of my Dyno run ! :-)
Less weight : marginally but not enough to be concerned with.
Holy Cowl fit : Will James has made an RV-10 lower cowl that fits the
BPE Cold air induction. He also has the Holy cowl for standard induction.
Net effect: Horsepower increases, Allen can tell you how much if you
contact him. All things being equal speed should increase, but it takes
a lot more ponies to equal 1 additional knot. (I'm not sure what the
ratio is but it's definitely NOT 1:1. Since there are no RV-10's flying
with cold air yet there are no performance numbers to report only
'hopes'. Perhaps later this year.

Subject: | Van's Motor Mount SB |
That's quite a leap from some complaints about a couple specific things.
I guess we should just bow to Van's ability to tell us how things should
be and be happy with that? Some people want improvements and some
people are content to follow the plans and recommendations to the T.
Nothing wrong with either method.

Is there anything these guys like about Vans? Seems like there are 66+

Subject: | Re: Van's Motor Mount SB |
Mark
Seems to me that Van's is simply saying that they will provide one
motor mount that works with the engines they have available ( and many other
Lycomings as well ) but don't expect them to modify it if it doesn't work
for a particular engine. That's the builders responsibility. Never in the
Service LETTER ( not bulletin ) is the word prohibited used. Van's doesn't
recommend 260+ HP but you can do whatever you want. It's experimental,
you're the builder, have at it. Hang a PT6 on the nose if you want but
Van's isn't going to offer any help. As it should be IMHO. The DAR is not
responsible for your choices of modifications either only that they are
installed according to generally accepted practice and conform to W & B
specs. He'll sign off on the PT6, give you a 40 hour flyoff, a look of
concern and if you haven't killed yourself in that time you can continue to
phase 2. That's the great thing about the experimental category. Indeed
this is a great kit and the fact that 60+ are flying so soon after initial
introduction proves it...

Subject: | Van's Motor Mount SB |
Michael,
"Good thing Tim didn't let them know he has a Lightspeed ignition on his
when he sent it back for modification, might be producing more than 260 HP"
seems a bit over the edge and close to being tacky.
I'm just happy I don't have as many as folks telling me how to run my
business as Van seems to have regarding this last motor mount war.
I built my Rv-10 with the motto "if it dosesn't fit make it fit" after all
you are the builder.

Yes, they will credit you for anything you want to delete from the
kits including the cowl. They do tell you if you order the cowl after
the fact expect the price to be a great deal higher. Makes sense as it
keeps them from having to deal with people that change their minds after
it shipped. As I said earlier, it's about an $800 difference.

Subject: | Van's Motor Mount SB |
It seems to me that its the sellers choice as to whether or not they
implement "suggested improvements" to their product. The market place will
eventually decide the issue. We do have the ability to make what we
consider to be improvements during the building process. Most of us have
made numerous changes (improvements) and keep on trucking without berating
Van for not doing it first. The basic kit is a great starting point to
built whatever comes to mind.

Subject: | Van's Motor Mount SB |
I think there is nothing like a lively debate on Primers and in this case
the engine mount SB, but I know there are a whole lot of us that are set on
Van's. I followed a high level composite company for a few years. I was set
on a 4 seater and in a way it is no different than what I am doing now. I am
getting a sense of is this the right kit for me.
I am still around and pretty sure I'll be starting this kit in the next
couple of months, this is only after extensive research and following this
forum for less than 1 year. I had 3 years at the other forum and finally
gave up on it.. Largely because most of the builders complained about one
thing or another and somehow the price of the kit doubled with carbon and
quickerbuild and other nice upgrades thrown in. I think that last time I
looked the kit was now 82K, it was 38K when I started looking into it in
1998.
So Van's doesn't want to cater to each of us and our individual engine
choice (not including their stock). Fine! Barret has his solution- so BPA is
solved, Thunderbolt is competitive in this market enough that they might do
something too, and so on but the good news is the rest of us who want a
stock engine from Vans don't need to worry that the cost will go up more
than 3% next year as a result of the few. Why am I going to build a RV-10?
many reasons. Mark Chamberlain for one. He invited me, never knowing who I
was, to see and fly and yes, fly in his plane. I never had anyone, and I saw
over 12 of the composites from the other company, offer to fly me in the
plane. Than there's Jeff Carpenter, who took a morning to go over the kit
with me when he had pressing engagements to get to, theres Tim, and Deems,
and John and most of you. Basically this group of builders is solid and we
feel comfortable enough to speak our minds, in jest and seriously. Let's
remember we are all in this for the same reason. A solid company with 30
years experience building the largest fleet of experimentals out there. I am
NOT building this plane to be unique or impress my neighbors, I'm building
this plane, a Van's, because I know they do care about the builders, and
they have the record to prove it.
Nothing wrong with venting on delayed shipments and expensive shipping for
2c items from Van's or SB's that we are not in support of- we should be here
to support each other as I know, I too will be frustrated and want someone
who understands my frustration to be there for me. We are!
Lastly, Vendor support- I see what Barrett did by offering to resolve this
issue as excellent. Jon's response, from Thunderbolt, was professional and
shows he too is in this to make it work for all of us and Lycoming and I
also took that he understood Van's SB. Stein last month getting on to
comfort those stuck in the D2AV debacle and Mike from Cleveland chiming in
at times as well. They all may be in for the business, but they care about
the builders too!
All in all we are a great group of builders with great vendors who are right
there with us building and supporting us. I think Van's has the right to
publish as many SB's as they wish, as long as they don't try to keep
everyone happy and have an affordable kit be out of reach for the rest of
those who just want to build it!
And with this, I end my rant!

Subject: RV10-List: Canada first Flight with James Cowl
This is a post of an offline note I got from Barry Martin
regarding David Corrigan's airplane and first flight in
Canada. The photos were sent inline, but I'll attach them
below. Not in order, in case the forum strips more than
a certain number.
Tim
-------
The first Vans RV-10 to fly in Canada took to the air on January 18,
2007 from the Charlottetown Airport on PEI. After approximately 16
months of building and, much to the delight of owner and co-builder
David Corrigan and co-builder Deryck Hickox, the RV-10 lifted off around
noon in clear skies and light winds, although the temperature was a
little cool, being around minus 5 degrees C. With the IO-540 purring
like a kitten, the RV-10 was through circuit height before reaching the
end of the runway.
Test pilot Glen McLarty took the RV to 4000 feet over the airport to do
the initial tests then headed north of the airport to finish the first
round of tests. In communication with the ground crew, Glen relayed that
the plane flew straight and level even with his hands off the stick.
The RV-10 is equipped with a Lycoming IO-540 that was rebuilt by Aerotec
in Halifax and has a MT 3 blade propeller up front. The aluminum portion
of the kit was of top quality. Since this was a quick build kit the
cockpit area and most of the wings were riveted together in the
Philippines while everything aft of the cockpit was riveted in
Charlottetown by Deryck, with bucking help from Dave, Terry Cooper and
me. When both pieces were fitted, not a hole was out of place. The
instrument panel was prefabricated by Gulf Coast Avionics in Florida and
I did the wiring and hooked up the panel. The panel had a few bugs in it
but most were found before the panel was installed. The panel is well
equipped with an AF-2500 engine monitor, Garmin 430, Garmin SL-30, PS
Engineering Audio Panel, Garmin GTX 327 Transponder, ATD-300 Traffic
Watch and a TruTrak Autopilot. As all the instruments are electrically
run, there is also a back-up battery.
This is the first homebuilt project for Dave, locally known as "The
Flying Real Estate Agent", but Deryck has over 30 years experience
building and restoring aircraft, much of it with the Canadian Warplane
Heritage in Hamilton. Deryck, originally from PEI, moved back after
retiring from Air Canada where he worked as an AME. Since starting the
project, Deryck has formed D. Hickox Aviation Services specializing in
aircraft restoration, fabric covering and home built aircraft. He can be
contacted at xxx-xxx-xxxx (trimmed for privacy) if you have a project
you would like him to build.
Dave is hoping to have the 25 hours flown off before Sun n Fun this
April. If you make it to Sun n Fun and see this beautiful RV-10 sitting
there with the registration of C-FYYG, you will know that he was successful.

Subject: | Van's Motor Mount SB |
On the engine mount issue, I agree with those who said that Van's has made
their engine mount for the engine they provide. Barrett's engine is not a
clone, but with the Cold Air Induction it is not "stock" IO-540, so the
engine mount is not necessarily going to fit. I don't have a problem with
this. Yes, it would be nice if Van's would start making their mount so it
would fit this sump as well, but I certainly wouldn't expect them to. I
would be quite surprised if they did. Are they creating a safety hazard
because they don't condone the Cold Air Induction? NO! Are they saying you
can't do it? NO! They just aren't going to go out of their way to make it
easier for you, at their expense. Deems, did they charge you for the mod?
Tim, did they charge you for the mod? I think the answer to both of these
is "NO". So, Van's accidentally helped Deems do something that they don't
condone to his benefit, but the SB is just to say that they won't do it any
more.
If you want to make a mod, you have to make it. I don't have a problem with
that.
I think the door handles are ugly, so I got some made that I like. I didn't
call Van's and ask them to make some that I liked and send them to me, much
less at no charge. I wanted an access panel in the baggage floor, so I
bought some parts and made one. These planes are not made by Van's
Aircraft. Deems' plane will have a manufacturer something like "Deems
Davis", so as long as he built it to his specifications, the FAA really has
no choice but to sign it off as airworthy (IMHO). They are certifying that
it is a safe plane, that it will fly, that nobody will get killed in it, or
that it is exactly like Van's designed it. They are just saying something
like, "It looks like an airplane" and that it is legal to fly and that Deems
has the right to fix it because he built it.
Some countries, as I understand, require that you build it exactly as the
plans call for to be legal to fly. The US does not (and apparently Canada
does not, with the Holy Cowl on the plane up there that just flew). If you
want to change something, change it and take your chances. If you want to
build it stock, build it stock and take your chances.
In short, Deems got lucky and Barrett is being very generous by bailing the
rest of the Cold Air Induction users out of the engine mount clearance
issue. Way to go Barrett and good for you Deems.

On the subject of engines, my reqts are pretty basic - standard IO540 D4A5
with one Mag replaced with a lightspeed plasma III.
Ignoring the Lightspeed, what is the difference between buying a Vans
Experimental 540 at $39,900 vs say an Aerosportpower at $40,300? $400 is
not a lot, but what added value do the engine (re-)builders give beyond the
standard engine provided by Vans?

That is what I call customer service. Barrett just earn a point for my
decision on the engine. It's the small things that help me make the big
decisions.]
I'm with Pascal. Unfortunately I am not inclined to send my mount from
South Australia for modification. Does Allen provide a stock IO540 (ie w/o
cold air induction) that does not require the mount mod, and at what cost?
If you're out their Allen, please reply off list if you wish.

many reasons. Mark Chamberlain for one. He invited me, never knowing who I
was, to see and fly and yes, fly in his plane. I never had anyone, and I saw
over 12 of the composites from the other company, offer to fly me in the
plane. Than there's Jeff Carpenter, who took a morning to go over the kit
with me when he had pressing engagements to get to, theres Tim, and Deems,
and John and most of you. Basically this group of builders is solid and we
feel comfortable enough to speak our minds, in jest and seriously. Let's
remember we are all in this for the same reason. A solid company with 30
years experience building the largest fleet of experimentals out there. I am
NOT building this plane to be unique or impress my neighbors, I'm building
this plane, a Van's, because I know they do care about the builders, and
they have the record to prove it.
Nothing wrong with venting on delayed shipments and expensive shipping for
2c items from Van's or SB's that we are not in support of- we should be here
to support each other as I know, I too will be frustrated and want someone
who understands my frustration to be there for me. We are!
Lastly, Vendor support- I see what Barrett did by offering to resolve this
issue as excellent. Jon's response, from Thunderbolt, was professional and
shows he too is in this to make it work for all of us and Lycoming and I
also took that he understood Van's SB. Stein last month getting on to
comfort those stuck in the D2AV debacle and Mike from Cleveland chiming in
at times as well. They all may be in for the business, but they care about
the builders too!
All in all we are a great group of builders with great vendors who are right
there with us building and supporting us. I think Van's has the right to
publish as many SB's as they wish, as long as they don't try to keep
everyone happy and have an affordable kit be out of reach for the rest of
those who just want to build it!
And with this, I end my rant!

I don't usually chime in with the simple one-liners, but.....Amen!
This sure is a great group of people we have, and the more who
join in the more fun it gets.
