You know....... A great candidate would be the 23012 used on the Taylorcraft....Good lift, great cruise speed/low drag, and good float on landing... Weav ----- Original Message -----

Subject: Re: Pietenpol-List: Re: Airfoil stuffI agree, I can almost feel a purist vs. GN-1 type war starting. Didn't people build GN-1s with J-3 wings? Would be interesting to know how those flew. I am building a long fuse piet and have not yet flown one but I have heard the same thing from several Piet bulder/flyers as Corky mentions, that the Piet hasno float (although it sounds like most people love the way it flys otherwise).This may be a real dumb idea but has anyone ever built a Piet wing to the plans and just removed the undercamber (make a flat bottom out of it)?Rick HollandPlease keep this discussion on airfoil going. I feel the Piet's performance could be improved, especially landing. I have flown many types of planes, SEL,but have never flown one that has no float, high drag, and a sudden drop out on landing like a Piet. I know it's safe if you expect it but I sure would liketo float like a Cub, Champ or even a Beaver.I have my ribs completed for 311CC but would be willing to build another set with another proven airfoil if I knew what to try. I mean no disrespect to BHPor the purists. If we didn't want to improve it we would all be building and flying Wright Flyers and/or Curtiss Pushers.________________________________________________________________________________

Subject: Re: Pietenpol-List: Re: Airfoil stuffConcerning Piet airfoil changes, if you plot the points from the 1934 wing plans on top of the single sheet rib plans that you get from Don (which Berniehimself signed, so I assume it is a tracing of one of his later rib creations),you will find that the undercamber is 6/32" LESS at the center and proportionally decreases to the front and back spar. Maybe Bernie himself deteminedin later years that you need that much undercamber. (Or I don't know how to measure off of plans ).Rick HollandYou know.......

I will say that Nathan Moss has had a good time in 41CC these last several months but not this weekCorky in La________________________________________________________________________________

I like this answer. There is NOTHING basically dangerous to be afraid of inthe Piet with the exception of trying to fly it like a plane it isn't. Ihaven't gotten to fly a Piet (anyone have one close to Southeast VA?) yetbut Edwin sounds right on target. If (from what I have heard) I tried toland a Piet like my Taylorcraft I'm going to do a carrier type arrival.Likewise a Piet landing in the Taylorcraft will end up as a "low pass" and Iwould never touch down. They are DIFFERENT planes! I just want to knowwhat the differences are and why. Like Edwin said, "Don't let thediscussion of airfoils be disconcerting to you. These discussions arebasically academic stimulus". With the proper data (if someone wanted to)you could build a Piet that landed like a Taylorcraft. I wouldn't, but youcould.Build your plane with the knowledge that MANY have been flown safely fordecades. I WOULD suggest that you get some dual time with someone familiarwith how a piet flys in a plane similar in handling. Any one know whatcommonly available plane lands like a Piet? From the discussions so far,DON'T USE A TAYLORCRAFT! They are NOT alike.Hank----- Original Message -----
