That's what I want to do, but I've been stymied by my inability to determine the proper blade chord; length and pitch are no problem, but I have no clue as to how to determine the appropriate chord. If you're making a Corvair prop, how did you determine blade chord? (For whatever reason, i don't get the pix that others refer to and they don't show up in photo archives.

Here's my take: The pitch lines on front and back are established by your math (mine's 66x34). As PF Beck says, "...the back of the blades are the most important..." He advises making sheet metal angles for each station so that the back comes out the same on both sides. As for the chord; if you make a smooth transition from the hub to the tip, and leave about 1/4" above and below the pitch line (especially in the front), the chord will form itself, assuming you want it to look something like a wing. Other writers have suggested using molding clay or 'profile guages' to get both sides to be the same at their stations. I'm using the profile guage suggested by Dan Helsper. His instruction book is also very helpful. If you really want some heavy duty reading on home-made props, check out 'How I Make Props,' by Alvin Schubert. I think I got it from the EAA website, but it's about 11 MB. I'll email you a copy, if you want. Gary Boothe Cool, Ca.

He is an inductee to all kinds of aviation halls of Fame, and was just inducted into a national hall of fame last week in Las Vegas (although I cannot recall or find the exact name of the award right now). In one part of his act, he comes over the field very slowly at a couple of hundred feet yawing from side to side, then he stalls it and does a one turn spin, recovers, and does a loop where the wheels touch the ground at the bottom, then back into the air for a roll before touching down on one wheel and rolling to a stop with the tail still in the air. One time in the 1990's an FAA rep allegedly saw him do the routine at a friend's party in airspace that allegedly was not "waivered airspace" and violated him for "reckless and careless" operation. Needless to say, he had a tough time proving that what he had done was "reckless" or "careless" and eventually gave up.

Prior to that, I was unaware that a Cub could actually be yawed around 180 degrees without changing direction... and then flown backwards for several seconds before doing a sort of uphill reversal... all within 50 feet of the ground. Sounds crazy, but that's exactly what he did (at least that's how I remember it and I don't think I'll ever forget it!) -Mike Mike Whaley MerlinFAC@cfl.rr.com ----- Original Message ----- From: "Dortch, Steven D MAJ NG NG NGB" > To: > Sent: Saturday, December 12, 2009 8:54 PM Subject: [piet] Pietenpol-List: How to fly a taildragger. from beechlist NGB" > > > > People say that is a normal flight for me!

We became friends several years ago. he described this as with two more variations. One was a farmer who just bought a plane, the other was a little old lady who won the raffle and would take off when the instructor handpropped the plane. > www.aeroelectric.com www.buildersbooks.com www.homebuilthelp.com http://www.matronics.com/contribution http://www.matronics.com/Navigator?Pietenpol-List ________________________________ Message 5 _____________________________________ Time: 09:57:44 AM PST US From: VAHOWDY@aol.com Subject: Re: Pietenpol-List: How to fly a taildragger. from beechlist I saw the Flying Farmer do an air show in Lynchburg VA. years ago. His show was the only one that made me scared for the pilots safety. He was so slow, your were sure the Cub would stall. He is a very skilled pilot indeed. The last I know of him he was based at the Flying Circus in Warrenton, VA. I think it was three years ago, I was working close by and stopped by the Circus. He was Driving an old van and pulling his plane. We talked for a few min's and I told him how much he scared me. He told me how much he loved doing what he does and that he was on the way to an air show right then. I don't remember his name, I have a friend who fly's Stearman's at the circus, I know he would know.

It'd make a great Christmas gift for my hangarmate, whose 'maiden flight' in his Pup was very similar to several of The Flying Farmer's 'maneuvers'. I can't find the DVD at the link provided by Charlie's website. Charlie's webstie is http://www.theflyingfarmer.com/ and the link he provides for the DVD is http://myworld.ebay.com/psai-fred/ Anybody know where to get the DVD?
