The Ultimate Electric 4WD Monster Truck!

Includes New Traxxas Stability Management (TSM) System,
Castle MXL-6s Waterproof ESC,
and Self-Righting Feature!

Designed For Brushless Power
Traxxas doesn’t make conversions. They build it right the first time. When it came time for the Traxxas engineers to design the latest in the E-Maxx line, they built it for maximum strength and durability so it would be ready to take on the market’s most powerful aftermarket brushless motor/ESC setups. So, the New Waterproof E-Maxx Brushless Edition can take almost anything you can dish out. The Brushless-Ready™ transmission is set up for hard-bashing 6S LiPo power. Plus, every element of the E-Maxx, from the motor, through the drive-train, to the tires is strengthened and ready for full-throttle action run after run. It’s the reliability and quality you’ve come to expect from Traxxas.

The New Castle Creations MXL-6s Waterproof Power System has all the features needed to handle the toughest demands. The ESC is ready for 6S LiPo configurations with massive 6.5mm gold-plated connectors, an integrated cooling fan, and a super high-efficiency heatsink. The ESC sends its power pulses to a 2200Kv motor that’s ready to propel your E-Maxx to lightning fast top speeds. To control motor temperatures, the aluminum motor can is machined to act as a large heatsink. The high-grade bearings built into the motor deliver maximum efficiency, and its high-strength Neodymium magnets give the Brushless E-Maxx unbelievable and outrageous torque. And like with all Traxxas trucks, you get an eye-catching painted and decaled body, pre-glued tires, and the most comprehensive instruction manual in the R/C industry.

Ultimate power is only part of what makes the Traxxas E-Maxx Brushless Edition the ultimate R/C truck. Traxxas has also included the best Traxxas radio system to date – the TQi 2.4Ghz Radio system. The TQi is telemetry-ready and can be set up with optional RPM/speed, motor temperature, and voltage telemetry sensors. Plus, the TQi is compatible with their new wireless module (part #6511 sold separately) that can turn your iPad®, iPhone®, or iPod touch® into an amazing source of real-time telemetry data as well as being a powerful tuning tool for your Traxxas truck! Plus, the new Traxxas Stability Management (TSM) allows you to utilize all of the extreme power and acceleration that was engineered into the E-Maxx Brushless Edition by making it easier to control on slippery surfaces, loose dirt, smooth concrete, and even ice and snow. Punch it off the line and TSM senses the vehicle’s direction and makes steering corrections to provide straight-ahead, full-throttle acceleration without spinouts, fish-tailing, and loss of control.

The E-Maxx Brushless Edition comes fully-assembled and Ready-To-Race (batteries not included).Traxxas stands behind their products and the E-Maxx Brushless Edition is no exception. They are industry leaders with top-notch support that cannot be beat. Traxxas has a staff of skilled sales reps and techs on-hand to answer your questions by phone, website, or e-mail.
