Default Spin recovery vs tail design

C of G ist critical for spin entry, but for recovering from a sustained
spin, mass distribution is far more important. (The rudder force must
overcome the angular momentum.)


Interesting noone has mentiond flap setting yet - setting the flaps to
negative is by far the best way to quicken up the spin recovery.

I guess pretty many pilots here have flown the ASW-20 - recovering it
with setting 4 (zhermal setting) with a medium to rearward CG ca take
up to 2 turns, but with flaps 1 (fully negative) recovery takes at
maximum 0.75 turns.
