Spin recovery vs tail design

This led to the NACA standard spin recovery technique which called for
anti-spin rudder while holding full up elevator until the auto-
rotation slowed and only then applying down elevator. The reasoning
was that full up elevator exposed more of the rudder to high energy
flow.

Trying this method in nearly any glider is a very safe way to get
killed.

I am pretty sure that most glasss gliders of the least 40 years will
not recover from a spin if the elevator is held fully up during the
recovery attempt - they simply are not going to stop rotation quickly
enough.
