Abstract

A remote control toy vehicle having a chassis with a pair of wheels respectively adjacent opposite ends thereof, a pair of electric motors of reversible polarity, drive mechanism respectively between said motors and the fore and aft wheels on opposite sides of the chassis, a battery, electric circuitry between the battery and said motors, separate switches in the circuitry of which one is operable to cause the motors to have the polarity reversed selectively to effect forward or rearward movement of the vehicle, and the other switch is operable to connect a resistance selectively into the circuitry of one or the other motors, whereby the motor having the resistance in the circuit runs slower than the other and the faster running other motor drives the wheels on one side of the vehicle faster than the wheels on the other side and thereby effects turning of the vehicle selectively in one direction or the opposite direction. The switches and battery are in a support remotely connected to the motors on the chassis by a flexible electric conduit of pre-determined length.
