i wante to make altitude holder control but i dont know how to make it can any one help me on that
Irrealistic edit
What airfoil is that ? A Clmax of 3.1, a stall angle of 19° for a cambered airfoil, and a Cl down to 0.1 just after stall are not real physical values. Too bad for such a nice design.. readers may take these values for the truth ; it would be better to use a real profile for this image...--Deltafox-net (talk) 00:09, 26 February 2009 (UTC)
