Remembering back to when I was young and beautiful and covered in helicopter grease ....... Sikorsky Sea King helicopter provides a couple of hints. First, most of the controls are push-rods and bell crank pivots match stowing hinge lines. Secondly, the tail pylon hinges away from the tail rotor drive shaft. They are disconnected when folded, but castellated gears nest to connect them in the flight configuration. Castellated gears would be great for torque tune controlled ailerons. You just need a few springs or cams to consitantly align inboard and outboard torque tubes.
