What is a spiral dive, what is a spin?.
A spin is when you stall the plane: one wing drops and remains stalled and the plane auto rotates. Releasing the sticks usually stops it in about 1 1/2 turns, or, if not, then use full opposite rudder to stop the spin and some down stick to regain airspeed, followed by a pullout. Since the plane is stalled, and especially in a flat spin, the forces on the plane are not that great. A spiral dive however is usually caused by a novice pilot putting on too much aileron too quickly before pulling the stick back too late resulting in the nose dropping to the vertical, and the plane winding up like a corkscrew. Putting on opposite aileron immediately and pulling out GENTLY usually saves the day if you have enough height. But the average novice usually tries to do both at the same time, which can cause even the strongest wing to “Clap Hands” (break in the middle).
