Hi Ron,

Greg from MDA. The servo on the exterior was Tom Chipleys sense of humor when he originally designed it, I don't think I even saw one of his own sporting the servo on the exterior other than the original prototype.

You can easily double side tape a servo inside the radio compartment and run a nyrod through the nose of the fuselage exiting right behind the engine and the throttle lever. Glue the nyrod casing in all the bulkheads and you're golden! Piece of cake, simple, no fancy physics and engineering degree needed
