Schumacher Menace GTR

The Schumacher Menace GTR is a radio-controlled car made by Schumacher Racing Products, powered by a nitro fuel engine. It is essentially a Schumacher Menace made into an on-road car. This is accomplished using lower shock towers, shorter dampers, different tires, wheels and other small adjustments. The end result is an on-road car that is just as fast as the Schumacher Fusion in a straight line speed but that can corner a lot faster due to its wider chassis and more stable nature.

Schumacher also produce an electric powered version, the Schumacher GTRe, which is similar in design but with a 540-size electric motor. The GTRe also includes the three-speed gearbox and disc brake system, something which is highly unusual for an electric RC-car of this type -- electric on-road cars usually use motor braking and no gearbox.
