RE: Spinner question
It would not necessarily stop at that point when it dies, but it will find its rest againt compression. When the engine dies, there is no more power to the propellor, but the airplane is still moving. As the air passes over the unpowered prop, then it will rotate it in a counterclockwise direction as long as there is little resistance to rotation. As soon as it hits resistance (compression) then it stops the rotation and stays there.
