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.

Abstract: A vehicle toy has two lateral sides, front and rear ends, an outer perimeter extending around the front and rear ends between the lateral sides, and three pairs of wheels, each pair having a common rotational axis. The wheels of each wheel pair are opposed to one another on the lateral sides. The wheels on each lateral side of the vehicle are arranged in a polygon at the outer perimeter, extending around the front and rear ends between the lateral sides such that adjoining pairs of the wheels define planes which are mutually transverse to one another and which entirely circumscribe the outer perimeter of the vehicle. Two wheel pairs are located proximal the rear end, with one of the two wheel pairs being oriented above the other, and the third wheel pair is located proximal the front end, so that the transverse planes form a triangle. The vehicle is driven by twin electric motors which are radio controlled for remote, independent and separate operation.
