How many gliders can be trimmed for hands off thermalling?

An instructor showed me, with spoilers open and proper
trim, the glider will stabilize in a slow descending
turn. Claimed it was good for getting out of a cloud.

Neat, but would not want to thermal with the spoilers
open.

Grob Astir CS works pretty well. Passed the urination-while-thermalling
test. So does my Mosquito.
Don't try it in a Ventus =o
As for getting out of a cloud that's a benign spiral. Lots to be found
by Googling this group, but ask your instructor for a demo too.
