I just made even better foil...a thicker one 17% thick with the best LD and lowest Cd for TAKE OFF and highest Cl with flaps 36 degs at Cl 2.35 !!!

You should never give up when you are onto something !

I need a 17% thick foil to make the structure lite and durable..13-14 % would have been too thin a foil. The lift of this foil at 36 degs flaps is actually OFF THE SCALE !
