ok reinstalling the game from scratch has fixed it. I think something got corrupted when it crashed or I screwed with some setting I should not have. Flys "normal" again now with stall limiter off. Strange. ......... now I gotta remap my joystick buttons, ugh.
Thanks for the ideas and feedback. See you in the skies.

As they should. Full aft stick is part of the snap roll entry. With normal C of G full aft stick should produce a stall at any speed. Don't see an issue.
But was more than that. The stalls and subsequent spins were freakishly quick and unpredictable and recoveries were strange to nonexistent. Something was definitely wacked out.
No worries. Reinstall did the trick
