I don't know if I'd run those things in a 33% plane. There are these things, I can't remember the name, but you put the servo in the trailing edge of the wing (or stab) but ahead of the aileron and you attach the servo arm to the control surface. It's a direct linkage control system. It was in the AMA Mag like 1.5yrs ago. Maybe someone has more info on it than I do....but it seems to be the best way of doing it something like that.
