Bill Modified his bird internally with provisions for sensors and wiring, hardpoint for aerotowing, dual landing gear plates so he can go trike or taildragger, dual flap servos. In addition, he moved his receiver and battery under the fuel tank, his throttle servo went just behind the windshield, and his rudder and elevator servos were placed in the rear fuselage. This all resulted in a perfectly balanced model with the cabin area completely empty, ready for whatever type of payload he feels like hauling that day.

Dennis built his Flyin' King to the book and saved some weight by leaving off the flaps. Dennis made a major contribution to our hobby by inventing and patenting the PCM technology that is now used in some of our R/C radios!
