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. -------- Semper Fi, Terry Hand Athens, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=409413#409413 ________________________________ Message 3 _____________________________________ Time: 06:05:14 AM PST US Subject: Pietenpol-List: Re: Engine Selection From: "jarheadpilot82" Mike, Define big.

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!

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?

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. rick h On Sat, Sep 28, 2013 at 2:15 PM, nightmare wrote: > pauldonahuepilot@yahoo.com> > > Welcome Ken (if i guessed right on your name) > Ask away, or use the search functions to find answers to your > questions.

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.

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 On Sat, Sep 28, 2013 at 3:26 PM, Mike Salerno wrote: > > > Big for me is HP/displacement.
