Abstract: A miniature gasoline engine is installed at the rear section of the model car. A first transmission gear is connected to and driven by the axle of the miniature gasoline engine, which in turn engages a parallel, second transmission gear, which is mounted at an end of a first transmission axle. A first bevel gear is provided at the other end of the first transmission axle, which engages a perpendicular, second bevel gear. The second bevel gear is connected to a center differential located in the center of the model car which in turn drives a second transmission axle (i.e., the main transmission axle). The second transmission axle runs through the center differential and axially through the model car, and directly drives the two front wheels and the two rear wheels, respectively.
