Abstract
A radio controlled toy vehicle has a central chassis, a front end mounting a pair of front wheels which is rotatably coupled to the front of the chassis and a pair of rear wheels rotatingly mounted to the chassis. A single reversible electric motor is provided in the chassis to selectively rotate the front end with the front wheels about a generally longitudinal axis through a partial rotation for steering or through as many complete rotations as desired for stunts. The electric motor is also drivingly coupled to the rear wheels to provide propulsion power to the vehicle. A power take-off from the motor includes a one-way clutch which rotates the front end when the motor is propelling the vehicle in a reverse direction. A stop is provided to limit the free rotation of the front end. The stop releasably engages a collar around a shaft rotating the front end and is overcome by providing sufficient torque to the shaft or the front end.
