Sep 19, 2005 · There has come up at the field, a discussion of CG being dependant on the particular airfoil shape; particularly with undercambered airfoils. In WinFoil, I used the same planform, and let the program tell me where the CG was for three different airfoils. I used the Clark Y (flat bottom), NACA 2412 (semisymetrical), and the NACA 6409 ... .
