Abstract
A stand-alone drive mechanism for a toy racing car. The mechanism includes individually controlled motors for operating simulated main drive wheels of a race car vehicle, a semi-concealed actual drive wheel for the vehicle, and a steering system. The mechanism is principally intended for use in connection with a construction toy set such as “K'NEX,” to enable construction of toy drag racing vehicles and the like. The simulated main drive wheels are elevated slightly above the support surface and can be rotated independently of the actual drive wheel, to simulate a “burn-out” sequence which typically precedes a drag race. By means of a remote radio control, the main drive wheels can be initially rotated to simulate “burn-out”, followed immediately by operation of the actual drive wheel to send a vehicle down a race path. The stand-alone unit includes a pair of small stabilizing wheels which, together with the actual drive wheel, elevate the simulated main drive wheel slightly above the support surface to enable free rotation without movement of the vehicle. The control system includes an automatic timer for performing a “burn-out” and …
