Spin recovery vs tail design

Eric was the accident investigator for this case and examined

recover with the stick pushed *fully* forward.

I've been doing some spins in the alto myself - the cause for this is
the poor (doenwards) deflection of the outside tail surface, the inner
having sufficient deflection but being blocked by the outer tail
surface.

But again, this is the theory, in practice, do whatever the AFM recommends.

Always a good advice.
By the way, it's pretty amazing how spin manners change with CG.
