During a correctly excecuted stall turn, the wing of the aircraft will not actually stall. This is becuase the stalling speed of a wing is a function of the load on the wing. Since there is no load on the wing, it doesnt stall.
There is a very indepth stalling discussion on the flying instrucors forum, and i dont want to hijack this thread, so ill be quiet now...
NB
