E-Maxx Brushless Edition, the Ultimate Electric 4X4 Monster!

Now Includes Two 11.1-Volt Power Cell LiPo Battery Packs and LiPo Balance Chargers!

This is the Traxxas E-Maxx Brushless Edition Ready-To-Run Montster Truck. The already-loaded E-Maxx Brushless Edition now includes two Power Cell LiPo batteries, two LiPo Balance Chargers, factory installed telemetry sensors, and the TQi transmitter with Docking Base as standard equipment. The two 5000mAh 3-cell LiPos unleash the full fury of the factory-installed and programmed Castle Creations Mamba Monster power system. This heavy-duty setup gives the E-Maxx wheel-lifting torque and brutally quick acceleration on the way to over 65mph—and you can prove it!

Super-Duty Revo driveshafts, Torque-Control slipper clutch, an oversized steel idler gear and rubber-sealed bearings are just a few of the features that make E-Maxx ready for all the horsepower you can handle. The Mamba Monster controller features a cooling fan and heavy-duty construction with oversized 6.5mm connectors, Traxxas High-Current Connectors, and the motor uses a 5mm rotor shaft for added durability. Traxxas’ innovative and secure speed control mount keeps the Mamba Monster controller and on/off switch in place without relying on servo tape.

This E-Maxx arrives Ready-To-Race with all the necessary telemetry sensors installed. Traxxas Link also lets you adjust the TQi’s pro-level features quickly and easily with its intuitive, high-def, touch-screen interface. While you hone performance with Traxxas Link, recharge the Power Cell LiPos with the included LiPo Balance Chargers for a perfect charge every time, no setting or programming required.
