Thanks for info. Can you show me a "WIDE" drag bucket airfoil or a pic.?? I never added camber and made less C/L..?? I did some crude test.. A.O.A ,adds C/L faster,per deg., than camber does. But camber stalled, slower and later. ?? Also, L/E radius. was super critical.. You can see how crazy this wing planform is from pic...Thanks for info. and time...
