Well stall also is when a wings AoA reachs a point where the airflow no longer can "stick" to the the wing so it breaks off short of the leading edge creating a turbulent wake, this wake increases with AoA until BANG stall.

Stall charactaristics differ from wing to wing, some are VERY sharp, whilst others, almost non noticable, especially with canards where the canard stalls before the wing.

This is all proper aerodynamic fact!

I think 3DRC gives a the best definition, although, doesnt matter what defintion you use Lord Lucan, as long you mention its a hell lot of FUN!
