ABSTRACT:
A radio-controlled vehicle toy is disclosed which includes a body, a caster axle mounted on a front end of the body and tilted backward from vertical, a front fork rotatable on the caster axle and rotatably supporting a front vehicle wheel, a rear-wheel drive coupled with a rear vehicle wheel, a radio-control receiver and a power source mounted to the body, and a pair of auxiliary wheels mounted on opposite sides of the vehicle body frame so as to be brought into contact with an underlying surface when the vehicle body frame leans laterally. A steering unit is mounted in a front-end portion of the body and includes a steering mechanism to rotate the front fork based on a control signal issued from the receiver and a resilient coupling which resiliently applies control torque to the front fork. The rear-wheel drive includes a motor which receives an electric current from the power source a speed reduction unit between the motor and the rear wheel, and a switch coupled across the motor, the switch being operable according to a signal initiated by the vehicle receiver to close and short the motor, which exerts a drag to effectively brake the vehicle toy.
