Kirk,
I agree with you that competent, current pilots, don't inadvertently stall any
ship. But your statement that you like a crisp stall, got me wondering. How do
you like a crisp stall, in the pattern, after some hard maneuvering to avoid a
mid-air? How do you like a crisp stall, when on the rocks, and get hit with a
large tail-gust?

The stall I got in my LS-7, after adding zig-zag to the horizontal stab, was
the worst stall I have ever seen in any sailplane. I mean she went near
vertical on me. Don't care to duplicate that in the above situations.

PS, I suspect the zig-zag delayed the *normal* seperation on the stab, but when
it did seperate, I lost all the down force from the horizontal stab and that
gave me the near vertical pitching moment. The wing may not have stalled at
all. Now someone please feel free to tell me just how full of Ka-ka, I am about
aerodynamics.
