Robert,
If the stab isn't stalling, can you explain the sharp stall in the LS-7 after
adding zig-zag and the elevator buffet in the LS-8, a good 5 knots above wing
stall?

Could it be this LS-8 wasn't set with the proper declanage? With all the
sloppy workmanship we are seeing these days, it wouldn't surprise me, a bit.
