Aviken,
Welcome! But fill us in-
Piet or Grega? Wood or steel tube? Short or long? Airfoil choice? Engine choice?
How far along are you?
Enquiring minds want to know!

Paul,
I forgot to add that I should be getting my fuselage back from William Wynne at
Corvair College #27 in November at Barnwell, SC. For anyone starting a project
and considering a steel tube fuselage and/or a Corvair it is a great place to
go and be a part of. P.F. Beck is happy to give rides in his Piet for anyone
who asks, and it is a great place to explore the Corvair engine.
WW is returning my steel tube fuselage with the die spring gear done, and the door
cut in for the front cockpit, so that should be available for folks to see.
Disclaimer - lest anyone thinks I am taking credit for someone else's work, I did
not weld the frame. I purchased it from Mike Frazier from WV. He built it according
to the Pietenpol plans (no wider and no longer). He did an outstanding
job of building and I was merely blessed enough to find it on Barnstormers.com
and buy it. The only mods I am doing are the die spring gear and door. So if
someone wants to see what a steel tube plans built fuselage looks like, then
come on. It will be a great weekend.

Mike,
Define big. By weight? Horsepower? several guys in the UK have O-235's, so that
is the biggest I have seen by weight combined with horsepower, in my extremely
limited experience around Pietenpols.
What are you trying to accomplish? Do you have an engine at a good price? Are you
thinking bigger is better in terms of HP and Airspeed? Have you played around
with the Weight and Balance to see how much weight you can carry without really
hurting your available payload desires?
Let us know.

To further elaborate on this, PA-18 Super Cub has a similar AD and
this caused a lot of surplus/serviceable struts to appear. I have four
rear struts set aside for the Pietenpol, and the plan is to have them
slightly shortened while keeping the adjustable fork on the lower
attachment point.
Bye!

Hello guys,
Work on the Piet is slowly restarting after a forced stop of a few
years (with a marriage and two funerals in between). At present, the
two focusing points are the landing gear and the engine conversion.
The former is the standard Jenny-style, of which the woodwork has been
completely done and is still missing some of the metalwork. Something
puzzles me, because among the various notes I took there's one saying
the axle should be 1 1/2", .120 wall, while the 1933 Flying and Glider
Manual specifies a wall thickness of 12GA which, according to my
conversion tables, should be anything from .080 to .109 depending on
which table I look at. Between the fact that I cannot remember where
the choice of the .120 wall came from, and the uncertainty in the
conversion of the original dimension, I'm still here at the starting
blocks. What are all you guys using?
SeeYa,
Andrea

Welcome Ken (if i guessed right on your name)
Ask away, or use the search functions to find answers to your questions. Your
not alone in not wanting to spend thousands on wood. Myself and some others
are using doug fir (although im a minority steel tube fuselage builder). Poplar
is another species some have used. My spars are laminated strips of doug fir
sandwiched with 1/8 okume ply and 1inch doug fir rails (i beam). Some have also
built I beams with all plywood web as well.
Some people have widened fuselage a couple of inches (including me), some lean
the back seat back 2-3 inches. You may want to see if someone has a piet in
your area so you can get a better idea of your "fit" in it. Lot of decisions
to be made, but for me , thats most of the fun. Paul

Big for me is HP/displacement. Looked to me that an 0-320 approximately the same
weight as the original Ford Model A.
I don't have anything available for weight and balance, so any help there would
be appreciated. What I am trying to accomplish is a better rate of climb so I
can fly on a hot Texas summer day better than just barely climbing.

Welcome Ken
One thing you may want to consider (in addition to buying the 4 Bingelis
book from EAA) is building a mock cockpit with cheap wood from the nearest
construction dumpster. You can figure out if you may want a wider cockpit,
seat leaned back, higher turtle deck, instrument panel, etc. and your kids
or grandkids will have a great toy to play with after. Plus if you have
never built a airplane before you can get a feel for cutting, sanding,
gluing, etc. with the cheap wood.

Recent tests include: Shock test on wing struts, and dropping aircraft from
3' on to runway.
Upcoming test: Landing in 50 kt head wind (is landing backwards really
possible?).

Maybe it is just a light oil film from the breather. The cont. engines will
push out extra oil if you run them at the full mark. I usually run mine
between 3 and 3.5 quarts to keep the mess to a minimum.
Oh, if your plane is covered with the Stitts / Poly Fiber it will not burn.
Let me rephrase that. It will burn if you hold a flame to it. When you
take the flame away it stops burning. If it is covered with dope, it could
burn.
Food for thought.

Michael, one thing to consider is the all-up weight of an airplane with the
O320 versus a more common Pietenpol powerplant. O320's usually have
starters, electrical systems, and metal propellers. The Model A to which
you are comparing the O320 generally would be hand propped, lack an
electrical system, and sport a wooden prop. Moreover, with a fuel burn of
at least 8 gph, you are going to want a bigger fuel tank. That will add
weight, too. The Pietenpol wing isn't designed to handle the gross weights
of airplanes that commonly use the O320 such as the Yankee, Cheetah,
Cherokee, or Skyhawk. Please don't think I'm opposed to the O320. I have
one on my Piper Pacer. But I wouldn't want it on my Pietenpol.
As a point of reference, density altitude here in northern Colorado is
probably a bit higher than anywhere in Texas, regardless of whatever heat
you may experience. We typically experience density altitudes in summer of
7500 to 9000 feet. Today it was only 6000 feet. There is a Pietenpol
based near me that has a 75 hp Continental on it (hand propped, no
electrics, wooden propeller). It does just fine even when density altitude
is high, though to be sure it is a single place airplane most of the time.
Its climb rate is elegant. Not fast, but stately.
The under camber of the Pietenpol wing creates a lot of lift, almost like
having flaps deployed all the time. I have some hours in Grummans (mostly
Cheetahs). That isn't true of the AA1s and AA5s, which were designed more
for eking out cruise speed.
Having said that, the Corvair is what I am going with. At close to 100 hp
(at sea level), it offers a good compromise between weight, lower fuel
burn (than the O320), and decent horse power, even when discounting for
losses due to elevation.
Good luck with this, Ken

Not sure why the good wood is only to be found on the west coast for
$1k. Swifton, AR is about 270 miles driving distance from Wicks Aircraft
in Highland, IL (just east of St Louis), and 30 feet of aircraft grade
spruce spar stock at Wicks would cost you a hair over $300 (at the
current price in their online catalog)...
Just out of curiosity....how big is big?
