Calgoddard (and Wombat)
It's important here to distinguish between stab tilt and stab twist.
Twist, to me, generally refers to a purposeful washin or washout of
the surface.
To use your example of a model flying straight on high torque- If one
puts a little wash in into the inside panel of the stab, it will twist
the tilt back in to the tail boom, and keep the model turning.
