Re the full-aileron cross-control suggestion a few posts up:

As I understood it, you were giving full rudder also?

Wow, I've never heard anything like that suggested before.

One thing I'd urge you to further explo how much variation in
airspeed can be tolerated before the glider is no longer in a stable
spiral? E.g. if the airspeed accidentally increases by X mph, do you
the dynamics change enough that you go out of control? The dynamics
that keep the various turning forces approximately balanced, and the
various roll torques exactly balanced, may be extremely
airspeed-sensitive.

I'm not guessing one way or the other, just curious.

I think you've misplaced this post. I haven't made and "full-aileron
cross-control suggestions" in this or any other thread.

What I *did* say is that my club requires members to do annual spin and
winch launch failure check flights. We do this at the start of each
flying season: members are not authorised to fly solo until these have
been completed. This sounds eminently sensible to me.
