ABSTRACT:
A device for starting a model airplane engine from a starter motor, electric drill or other drive means. The device for starting a model airplane engine comprises a cylindrical hub having an open end and a closed end, the hub having tubular sidewalls attached to periphery edges of the base and extending towards the open end of the hub. The tubular sidewall is provided with two slots. The slots are positioned diametrically opposed across the axis of revolution of the hub. A substantially flat bumper bracket extends outwards from the hub through the slots. The bumper bracket is equipped with elongated side bumpers attached at opposing ends of the bracket, the side bumpers extending forward from the hub and adapted to interface with and torsionally drive a model airplane propeller. The starting device transferring rotary torque from the drive means to the airplane propeller and engine to crank the engine and thereby facilitate starting of the engine.
