Has anyone out there done a little surgery to a Hangar 9 Edge 540 ARF and mounted the Elevator Servos in the tail. If so I would appreciate some feedback as to how this plane balanced afterwards and what the general affect was to the plane. I am planning a Saito 180 for this plane. Also how far forward did you mount the servos.

Also what way would you guys recommend mounting the engine, sideways or inverted?

Thanks in advance
