ABSTRACT:
A radio controlled steering device for a two-wheeled vehicle toy has a tiltable rear wheel movable to a tilting direction by a servo motor. Tilting of the rear wheel shifts the center of gravity to either side of the normal center of gravity to induce rotation of the front wheel in the direction of tilt of the rear wheel.
