Varies considerably with C of G position as well as from type to type. It
can also vary with mode of spin entry. The requirement, at the time of
Certification of the ASW20 in 1977, was "after a 5 turn spin, with the
aircraft in the most adverse configuration (normally this would be extended
aft C of G and usually positive flap in a flapped glider), the glider
should recover within 2 turns from intiation of recovery, which was,
central ailerons, full opposite rudder and stick progressivly forward until
the spinning stops. I did the UK testing for UK Certification of the ASW20
when it first arrived here. It came out in a little over 1 turn in the
worst configuration.
Some types may need full forward stick at aft C of G.
