Traxxas makes it easy to convert your E-Maxx® 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 3997X 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.
