The E-Maxx (#3905) was designed from the ground-up to handle extreme brushless torque and power. Traxxas makes it easy to convert from dual motors to a single brushless motor setup. Choose your favorite electric power plant and bolt it in using the Traxxas single motor gear cover and blue-anodized aluminum motor plate. The two-piece gear cover keeps dirt and debris out, while allowing easy access to the pinion and spur gear. A removable plug makes slipper clutch adjustments easy. These parts give your brushless install a clean factory fit and finish.
