Hi. I'm building a P39 Airacobra kit. The directions call for the aileron servo to be centered in the wing. In order to do this, I will need to cut a square in the center rib deep enough to accommodate the servo. I'd prefer to keep the rib intact, because that seems to be a lot of rib to remove at such a critical location.

The ailerons move with torque rods. Does the servo have to be perfectly centered in order for the ailerons to move correctly (ie equal throws)? If I install the servo just to the left or right of the center rib, can I still get it to work correctly?
