An interesting extract from the Robin 2160 POH:
"In a spin of more than 3 rotations, the engine is likely to stall. This raises no difficulty: the propeller should windmill once airspeed is restored and restart the engine.
(CAUTION: engage engine starter only if propeller stops rotating)"
The Robin 2160 has a fixed pitch propeller and a Lycoming 160 hp engine. The above strongly infers that the propeller will be caused to rotate at very low speeds.
