Abstract: An elongated substantially hollow body supports a pair of motor drive units, a battery power supply, and a radio frequency receiver and controller module. A pair of axles are rotatably supported near the frontal end of the elongated body and in turn support a pair of large diameter wheels. The motor drive units within the body are operatively coupled to the axles and are able to differentially drive the wheels. The position of the axles and wheels near the frontal portion of the vehicle results in the extension of a substantially greater portion of the body away from and beyond the wheels. Thus the extending portion of the body defines a trailing end. A control transmitter provides independent operational signals to each of the motor drive units to differentially drive the wheels. Each time the direction of travel of the toy vehicle is reversed, the reaction torque applied by the motors to the body causes the body to flip about the axles and invert bringing the trailing end to the opposite side of the wheels.

The wheel has a hollow shell of rubber or some other flexible material and opposed sidewalls of the wheel are moveable relative to each other to compress the axial width and increase the diameter.
