Bryan-

I'm a relatively new owner of a Std Jantar 3 (about 15 flights so far). I have performed stalls in various configurations but have not spun it yet. Everything I've seen is very similar to the other gliders I've flow (ASK-21 and a Ka-7). If you're uncoordinated you'll tend to drop a wing, but it's nothing exciting or unexpected.

Hopefully others can post their experiences as well.
