Hi banktoturn,

My experience with aerodynamics, airfoils, and design is exclusively with models, so I don't know the current numbers for full-size aircraft. (I have a private pilot's license, but don't do full-size aerobatics.)

"Beneficial stall" is handy for producing snap rolls quickly, on command... a trait not so desirable on full-size aircraft, except maybe for a few aerobatic ships.
