Right Rock, They use it to trim the airplane. I have noticed that a lot of biplane models must use a lot of trim in the elevator in order to fly level (kinda). I think that this will allow me to fly without the elevator deflected. I plan to start with the h-stab set at the plan setting, and make minor adjustments at cruise and at full throttle. I think that I'll probably go back to the stock setting again for landing. That's the plan for now, but the best thing about this set-up is that I can put it where it does best.
