If you are comparing airfoils to the Piet, remember that the Piet isreflexed and if you compare the pitching moment the Piets is very low. Ifyou change this, you have to compensate by changing something else such asthe area of the tail surface and so on and so on and so on . . . . . . . .________________________________________________________________________________Date: Tue, 21 May 2002 07:54:11 -0700 (PDT)

Yes, thats in there. You will note that the Pietenpol airfoil has a higherpitching moment than either the NACA 2412 or the NACA 23012. It has aslightly lower pitching moment than the NACA 4412.----- Original Message -----
