Abstract
A chassis module for removably mounting in an opening in the fuselage of a model airplane is arranged to support an engine, a radio, receiver, a fuel tank, a battery and servomechanisms controlled by the radio receiver to control the engine throttle and movable flight control surfaces on the model airplane. The module may include energy absorbers to provide protection to the chassis module and the components mounted thereto in the event of a crash of the model airplane. A magnetically operated latching reed switch is disclosed for applying and removing on-board battery power to the on-board electrical equipment by the use of a magnet brought near the vicinity of the switch from outside the model airplane.
