ABSTRACT:
An engine for a radio control model includes an input axle partially extending out of the engine. A drive device is laterally mounted to the engine for driving the input axle when starting the engine. The driving device includes a first casing and a second casing abutting each other and respectively made of insulating material. At least one drive element is rotatably mounted in the driving device for driving the input axle. A polygonal hole is longitudinally defined in the at least one drive element and adapted to be connected to an extra power source. A conducting ring is sleeved on the at least one drive element and a wire is electrically connected to the conducting ring and a spark plug that is mounted in the engine such that the spark plug sparkles and the input axle provides torsion at the same time for starting the engine.
