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.

Performance

* 0-60 MPH: Estimated under 2 seconds with ideal configuration and conditions. * Top speed: Estimated 70 MPH with high speed gearing.

Criticism

* Gearbox is not natively adjustable. * Castor not adjustable. * Toe not adjustable on the rear wheels. * Open differential (i.e. not adjustable). * The gearbox is open and debris from the road can easily enter and thus break one or several gears. * To access the gearbox when making modifications or repairs, major parts of the car has to be disassembled, e.g. the engine has to be removed.
