Default 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

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.

Read more carefully. I didn't write anything about trying a recovery
with full up elevator. I wrote "until the auto-rotation slowed and
only then applying down elevator"
