| Subject: | Gardiner's Corvair issue, or how not to cool the Corvair |
in your Pietenpol
I'm sure many recall the posts Gardiner made to the list recently about the
unfortunate problems he encountered with the Corvair engine he has installed
in his Pietenpol. There was the suggestion on his part that it may have been
due to subpar workmanship during assembly of the engine, which was assembled
by one of William Wynne's former hangar crew. Gardiner took the engine down
to William Wynne, and a partial teardown and analysis of the engine revealed
that it had been suffering from a combination of sketchy timing and
inadequate cooling, leading to severe detonation. The timing issue stemmed
from having an equally sketchy individual (not related to William or one of
his associates) make modifications to the distributor, and the cooling issue
stemmed from a number of flaws in Gardiner's particular cooling
configuration. William has put a detailed post on his site explaining
exactly what happened, and how to avoid these issues:
http://flycorvair.com/pietengineissue.html
I highly recommend giving it a read if you are at all interested in using a
Corvair, or if you are already committed to using one. Plenty of good
information.
Gardiner,
We wish you the best with getting the 'Vair back together and back on your
Piet. We hope you can get all the kinks sorted out and are able to fly her
to Brodhead this year! We'll be there with our new Piet, and we look forward
to seeing yours. Have a nice weekend,
Ryan

| Subject: | rib test, wood failure |
I have two completed ribs and I was looking through the archives to find ways to
test them. Could anyone point me in the right direction?
I'm sure I couldn't build a rib worse than these two. I forgot to glue the backs
of some gussets on one, and I started pulling one out of the jig too soon,
so I'm confident that these two will be the worst of my lot.
Are there any numbers on what the rib should be able to take?

I'm sure you'll get some more technical answers later. but if you can tug at the
gussets without them coming loose and they held their shape well after coming
out.and you used good clean wood without knots or deformities I'd guess they
are pretty good.( of course unless you're wanting to test them to destruction
you have to use some judgment on how hard to pull on the gussets.there was a
post a while back about a wing that had been flying for some time and the gussets
peeling off when they checked them so it would be good to do that before constructing
a wing with them I'd guess. I have in the past made a master rib for
a pattern and sanded the others as needed on a belt/disc sander till they were
a very close match.and when I used plywood for ribs on another project I used
a ball bearing pilot router bit to trim them all to the master rib after clamping
them to it. lots of ways to check them. Raymond

The third just came out of the jig beautifully. They look great, and they're very
solid. I'm going to mock up two on some two foot spars, tack some leading
and trailing edge on and pile some weight on from a few different angles.
I just bought another bingelis book, it will be here shortly. I do have a question
about grain, though. What is the preferred direction of the grain in relation
to stress? Should rings be horizontal, vertical, or it doesn't matter?

Good point! Mogas is foul smelling swill compared to the sweet, sweet nectar
that is 100LL. Airplanes that consistently have their tanks full of mogas
just don't smell right....I want my airplane to smell like an airplane darn
it, not like the old jalopy next door! :)

can anybody give me a pretty good guess as to where the center of gravity for the
pilot or passenger is supposed to be in relation to the seat back? I'm working
to get the W&B figured out on the project I bought from D.J. and the fuselage
has been stretched quite a bit.I just don't know whether to use something
like 4 or 5 inches ahead of the bottom of the seat back as the distance for pilot
or passenger weight calculations or what. hope someone can enlighten me here.

I can give you a good idea if your GN-1 is according to the plans. Beware, the
weight and balance information (example) in the plans is wrong. Look in the

Raymond,
If I recall correctly, DJ's project was a GN-1...if that is the case I can't
say how much what I say applies to a GN-1, as I am referring to Pietenpol
information.
According to Don Pietenpol: "not under any condition should this airplane be
flown with the C.G. more than 20" from the leading edge of the wing".
You can use any reference you like to establish where the C.G. falls...the
firewall, leading edge of the wing, it doesn't really matter. But what you
must do is to use the C.G. that your W&B gives you to determine where that
falls in relation to the leading edge of the wing. HTH,
Ryan

Tom that is good to know.I have never figured out how to search the archives. maybe
that's the reason I come up with questions that have been covered so often.if
you would not mind visiting off list about it I'd be glad to pick your brain.
but what I am trying to use is a calculator that is available on the Kansas
city Dawn patrol website.I have the distances measured on my airplane using
the firewall as a datum.as well as empty weights at the wheels and everything
level.if I could just get a good centerline for pilot weight.I seem to remember
reading once it would be at about a person's hip bone when sitting. that probably
depends on the reclining angle.and whether it is a normal person or someone
like me with long legs.but the figures I am coming up with sure don't look
usable.

Raymond,
If the plane is built according to the plans, the moments provided are all you
need. Learn how to compute your c.g. with a pencil and a piece of paper (backwards,
in your sleep) first. You have to understand it -- there is no shortcut.

Raymond,
Searching the archives isn't too difficult. First off, you have to get
there. You can find it at:

The first step is to use the 'Select Archive' dropdown to choose Pietenpol.
I would leave 'Message Order' at Newest First.
I like to set 'Output Method' at 3 frame Index.
Then you arrive at entering your search. There are instructions on the site.
To boil them down:
If you want to search for one word, just type the word and click Begin
Search. For example, if I want to find all posts that talk about Stromberg
carbs, I'll search for 'stromberg' (minus the quotes).
If I want to search for a phrase, I can just enter the words. Maybe I want
to see what was posted about how to build landing gear. I can enter 'landing
gear', and it will find every post that contains the word 'landing' that is
followed immediately by the word 'gear'.
Maybe I want to find out about how elevator travel might relate to throttle
usage. Well, odds are I won't find a two or three word phrase containing
those words right next to each other that is common to many posts. In this
case I can search for 'elevator & throttle & travel'. This will show me any
posts that contain those three words, whether they are next to each other or
not.
Maybe you decide you want to see if there is any information about
Pietenpols with Warner engines, or with Lambert engines. There may be posts
on the list about one, or the other, but not both. To find them you can do a
search for 'warner | lambert. The | character, which you can enter by
hitting Shift plus the |\ key, means or. So you are searching for posts that
contain the words 'Warner' or 'Lambert', but not both.
If you need any more help with searching in the archives please feel free to
shoot me an email. I can talk you through it on the phone if you are more
comfortable with that, just let me know. Good luck!

well that's one of the problems -it wasn't built to plans-it has quite a bit of
stretch and as I understood from a previous post the plans had wrong info anyway.

| Subject: | Re: Gardiner's Corvair issue, or how not to cool the |
Corvair in your Pietenpol
Interesting writeup from WW, one thing mentioned that I do not have is an
air passage between the left and right eyebrow baffles, has anyone seen this
on a Corvair/Piet installation? Shouldn't be too hard to add a 2 1/2" Scat
hose between my eyebrows.

O.K. You have to put the plane on scales, weigh it empty -- compute the empty
c.g. Sit in it, compute the c.g. and derive the pilot moment. Sit in the front
hole, compute the c.g. and derive the passenger moment. I found the passenger
moment to be in error on my plane. The scales do not lie. I had to make
a new motor mount and cowling and correct for short tach, carb heat and oil temp
lines (not fun). Learn it.

Well now that's what I need! gonna need a helper but I get it now.instead of using
my weight or a pre-determined one at a certain distance.I can do it with the
scales and get a real true figure. Probably something I can get done.I know
I am way too far forward CG. which is unusual.but that is a way to get some realistic
figures. thanks! Raymond

I think I read in one of the Bingelis books to use your bellybutton as
your center of gravity, but when I weighed myself in the airplane, my
moment was a few inches forward of my bellybutton. I agree with the
advice to do your weight and balance with the planned pilot sitting in
the pilot's seat, then derive your moment.
