Abstract
A structure for a starter (driver) of a miniaturized remote control model car engine is able to perform perfect separation of the starter shaft from the engine as soon as the engine has built up its normal speed with the aid of the slanted surface and chamfered edges formed on its coupling plate, and the retrieved starter shaft never forwardly excurses to recontact the engine shaft by a steel ball positioning device. With this structure, the extra mechanical loss and damage to the mechanical parts can be prevented in model car engines operated at an extra high speed.
