As a side note to the "AHII FM" thread. Some people seem to have a misunderstanding of what a stall is.... (and I didn't want to hijack the thread.)
A Stall can occur at any speed, attitude, or altitude . A stall is defined as "the angle of attack exceeding the critical angle of attack of the wing." A roll or spin induced from a stall is an effect of one wing stalling before the other. If you stall both wings at the same time (ie. you are "coordinated") there will be no roll or spin, the nose will drop and you will gain airspeed. As you get slower, it is easier to force the angle of attack past the critical angle of attack, because at slower speeds, you need more angle of attack to create enough lift to keep you airborne.
An "Accellerated Stall" is just a stall that is "accellerated" due to control surface inputs (Elevator, aileron, or rudder) at speed. A "snap roll" is an example of a "accelerated stall" manuever. Essentially, the pilot, through control inputs, stalls one wing before the other to maximize a roll manuever.
Each plane has it's unique stall characteristics. This is due mostly to differences in weight and balances, engine torque, p-factor, slipstream, gyroscopic precession, and wing shape. But all planes in AH can and will stall, all can spin. Just some are more forgiving in the amount of time it takes to recover a bad stall.

PS. Just in case: Angle of Attack is the angle of "wind" to the chord of the wing. Critical Angle of Attack is the angle at which the "wind" can no longer flow smoothly over a wing.
