Traxxas' E-Maxx Brushless Edition is better equipped than ever! The already-loaded E-Maxx now includes Traxxas Stability Management waterproof electronics, and the TQi transmitter as standard equipment. This heavy-duty setup gives E-Maxx wheel-lifting torque and brutally quick acceleration on the way to over 35mph with two 7-cell NiMh batteries—or blow by 65mph by installing optional Power Cell 3S LiPo batteries!

Only Traxxas lets you experience 4WD excitement year-round, no matter what Mother Nature has to offer. Water, mud, and snow don't slow down the E-Maxx; its electronic speed control, receiver box, and high-torque digital steering servos  are all waterproof for worry-free fun in wet conditions that send other trucks back to the workbench. Drive the E-Maxx where you want, when you want—the only limit is your imagination.

Give E-Maxx all you've got; its Brushless-Ready transmission is built for hard-hitting 6S LiPo power with the burliest brushless motors, and every component between the motor and the tires is proven tough for full-throttle fun, pack after pack, with the durability and reliability you expect from Traxxas.
