"NASA droops" .............could be added to an existing wing. The NASA droop is a leading edge "anti-stall" modification, usually applied to the outer 35-40% of a wing. The easiest method to modify an existing plane to cure nasty stalling habits is the use of stall strips. Applied to the inner 20-25% of the wing, the stall strip is a small change to the leading edge that produces turbulence to that part of the wing at higher angles of attack, causing the stall to begin at the root. ......... Thus we will have a slightly higher stall speed, but the stall will at least be manageable. Plus - the beauty of the stall strips is that you can just pin them on and experiment till you get the effect you want, then make them permanent! So if you have a vicious stalling plane on your hands, don't just try to cope till you crash it - add some droops or stall strips - let the plane age gracefully, THEN crash it!
