To clarify my previous post - Recovery at incipient stage - I meant that the spin does not fully develop until anywhere from 2 to 6 turns.
Anywhere from a situation where the AC has gone from half a turn to about 2 turns therefore - use the incipient recovery technique.
Thereafter its the standard spin recovery technique.
As previously mentioned , even a Cessna 152 will not recover instantly when the autorotation has set in and the spin is fully developed.
Don't even think of doing this unless you have loads of height, I previously span a 152 which took 4000' to recover , we found out later the ailerons were slightly mis-rigged!
