Agreed, i absolutely love 90 degree trailing flaps on the HP. I have tried the benign spiral in several ships, and the '14 was the only one that i would actually trust to stay slow and stable in rougher air. It does work in other gliders, but it needs to usually be set up properly, and assumes no large turbulence.

I had already descended 2k feet or so completely hands-off and when i bailed out, and the glider was completely stable, exited the cloud upright, and continued flying away from me...couldn't ask for better performance in a dire situation.
