    Subject: 65HP climb rate
    --> Pietenpol-List message posted by: "Gadd, Skip" <Skip.Gadd@ssa.gov> Sometimes all the numbers and formulas really confuse my tired old brain, but I can add this. I had the pleasure to ride in Williams Corvair Piet at Brodhead, Gus was the pilot and as mentioned he is a big guy. The main thing I remember is the way I was pushed back in the seat at the beginning of the T/O roll. I have had rides in about a dozen Piets and GN1s and Williams had by far the most seat compression. I don't remember anything about climb, guess I was too excited. I do remember that Williams Corvair was also the quietest Piet I have heard, you could hear the prop, and almost nothing else, when it flew overhead at something less than pattern altitude. Skip, still working on L/G and turning my hubs. ....even at cruise I KNOW the 'vair gives more than 60hp. DJ > against these claims of high HP from a Corvair. > walt

    From: "Kent Hallsten" <KHallsten@governair.com>
    --> Pietenpol-List message posted by: "Kent Hallsten" <KHallsten@Governair.com> Kevin, My server at work won't let us access "angelfire" websites. Would you be able to send this airfoil to the Matronics Photoshare, if it's not too much trouble? By the way, I don't know if everybody knows this but we can list files in this area, it's not just for photos. Thanks Kent Hallsten Currently retaking control of "my airplane factory" from the wife and kids -----Original Message----- From: Kevin Holcomb [mailto:ksholcomb@mindspring.com] Subject: Re: Pietenpol-List: Airfoil --> Pietenpol-List message posted by: "Kevin Holcomb" <ksholcomb@mindspring.com> .... detailed in that region. The data and coordinates are on the Air Camper page within my personal web page which can be found at: http://www.angelfire.com/va2/aerodrome/ It is a high lift/high drag airfoil as one would expect from a low and slow flier.

    Subject: Walt's pictures
    --> Pietenpol-List message posted by: "Oscar Zuniga" <taildrags@hotmail.com> Walt was kind enough to point us to a site where pictures of his plane (and of him) are located, but here's a straight shot to his picture so you won't have to snoop to find it: http://gtalexander.home.att.net/piet.html She's a beauty, Walt. I guess you and Corky got yours in the air within just weeks of each other, eh? Maybe the last two to take wing in 2002 (that we know of).

    Subject: trim system
    --> Pietenpol-List message posted by: "Oscar Zuniga" <taildrags@hotmail.com> If I might add my two cents' worth to the trim setup discussion, I've seen pictures of the Taylorcraft-style setup with mini-tabs on each side of the tailcone near the horizontal stab and it looked interesting and easy to do. However, remember that most Piets tend to be tail-heavy, so adding anything back there is going to cause weight/balance problems. Better to go with the spring or bungee setup like Mike Cuy is using, providing biasing force to the elevator controls. And as for Corky's idea about making the HS adjustable for doing final rigging, it's certainly worth thinking about when building the HS attachment. The alternative is having to 'torque' the HS by differentially tightening the brace wires. Or finding that the plane needs to be trimmed with the elevator out of trail with the HS to fly straight & level, which can only mean more drag. And we certainly don't want more drag on a sports car like the sleek and sassy Pietenpol, do we? ;o) Oscar Ziga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net

    --> Pietenpol-List message posted by: "Kevin Holcomb" <ksholcomb@mindspring.com> I sent the files to you via email. Hopefully that will work for you. Otherwise you might try a computer somewhere else, some libraries have a setup. There is nothing on my site that should be offensive in a professional environment.

    Subject: Re: trim system
    --> Pietenpol-List message posted by: ZigoDan@aol.com The only draw back about Mike Cuys trim system is that if for some strange reason a cable breaks, or there is loss of stick control to the elevator there is no back up. That is why on Cessna 150, Champs, Cubs, the trim is a total different system. You can land a 150, champ, or Cub in an emergency with trim only. I have thought about building one elevator with a cockpit controllable tab. Dan
