ABSTRACT:
A system for remote control starting of model engines of the internal combustion type, used on model airplanes, automobiles, boats and the like, while stationary, in motion, or in flight. A starting gear or pulley is mounted by a combination roller bearing and one-way clutch directly on a section of the crank shaft of the engine. An electric starting motor drives the gear or pulley for cranking the engine. The motor is energized by power from a battery pack carried on the vehicle via a circuit having a pair of diodes therein, the voltage drop across which serves to energize the glow plug or igniter. A start switch in the motor circuit is activated by a servo device in turn activated by signals received from a radio receiver on the vehicle. The servo device also activates a choke plug for the carburetor air intake, to aid in initial starting of the engine, and a cut-off valve in the fuel line to assist in starting the engine after stalling, while stationary, on the ground or while in motion, as when an airplane is in flight.
