Now with Traxxas 2.4Ghz LINK Radio & 2 Batteries! The Ultimate Electric 4x4 Maxx Monster!
Now Includes TQ 2.4Ghz Radio System with Traxxas Link!
Plus, Waterproof Electronics!!!
This NEW Traxxas Bonus Edition
comes with two basic 7-Cell NiMh Batteries FREE!* The New Traxxas E-Maxx® takes 4WD monster truck thrashing to the next level of fun and excitement. To go along with the torquey 16.8-volt EVX-2 dual-motor power system, key improvements have been engineered into the suspension, driveline, chassis, and electronics to make this the toughest, most versatile E-Maxx ever. The new E-Maxx is equipped with Revo® sealed pivot ball suspension; dual-servo steering; an all-new transmission; Revo sealed differentials; a new, longer chassis; and weather-sealed electronics. And that’s just the start. Everywhere you look on E-Maxx Traxxas engineers have thoughtfully integrated new enhancements and features that make E-Maxx stronger, easier to use, and most importantly, more fun!
70% of the Earth’s Surface is Covered by Water
E-Maxx Says . . . “Bring It On!”
E-Maxx is equipped with sealed electronics that eliminate boundaries and let you drive where you want to drive. E-Maxx lets you blaze new trails through water, mud, snow and other wet-running conditions that wouldn’t have been possible before. Since water is no longer the enemy, E-Maxx opens up a whole new world of 4x4 adventure and fun.
Traxxas TQ 2.4GHz Transmitter and 5-channel Micro Receiver
The E-Maxx now includes the Traxxas TQ 2.4GHz High Output radio system with Traxxas Link™. This new system offers the unbeatable convenience of “no channels, no crystals” 2.4Ghz technology, and the long-range security of a high-output signal—but that’s just the beginning. The new, patent-pending Traxxas Link technology stores settings for up to 20 Traxxas Link-enabled models, with no naming or “model memory” settings required. Just power up the transmitter and the model you want to drive, and the settings for that model are dialed in immediately! The new TQ 2.4GHz High Output radio is also fully adjustable; steering and throttle end points can be set precisely, and the Multi-Function knob can be programmed to control Steering Sensitivity (Expo), Throttle Sensitivity (Expo), Steering Percentage (Dual Rate), Braking Percentage (Dual Rate), or Throttle Trim.
Ready For Brushless
E-Maxx is equipped with an all-new transmission that’s been engineered to handle nearly 2 ˝ times more torque than the original, and yet do it in a more compact package. Extra-wide gears, smart use of steel components, and the Revo®-Spec Torque-Control™ slipper all combine for the strength needed to handle the extreme power and torque that’s possible with today’s battery and motor technology. The design positions the motors closer to the chassis for a lower cg and improved handling. An optional bolt-in two-speed is available for shift-on-the-fly gearing options. Revo-Spec large diameter sealed driveshafts and sealed differentials are used for massively increased torque handling and long-lasting performance. Since the diffs are completely sealed, they can be fine-tuned with different oil viscosities to adjust the limited-slip action.
16.8-Volt Power System
The waterproof Traxxas EVX-2™ is optimized to deliver massive power from dual 7-cell battery packs. The EVX-2 packs a serious punch, belting out over 16 volts of power to the twin 550 high-torque motors. Titan 550 motors feature 30% longer motor armatures than a standard 540 size motor for monster big block torque. An internal fan helps keep the motors running at optimal temperatures for maximum power. Mash the throttle for wheelies on demand and absolutely mind-bending monster truck action that only E-Maxx can deliver. Designed by Traxxas, the EVX-2 features three drive profiles, thermal shutdown protection, and Traxxas high-current battery connectors. The EVX-2 also includes our exclusive, patent-pending Training Mode.™ This profile reduces the overall power output of the EVX-2 by 50% making it easier for young or new drivers to develop their control skills before unleashing full-power operation. The EVX-2 is manufactured by Traxxas to ensure the highest level of quality and support, plus it’s backed by the exclusive Traxxas Lifetime Electronics Warranty.
Extended Wheelbase, Low CG Chassis The chassis design is all new with 30mm of increased wheelbase for improved stability. The new battery compartments position the batteries lower, angled in towards the center of the truck for improved handling and cornering stability. The new stronger chassis braces work together with a new center skid plate to greatly enhance chassis strength and torsional rigidity.
Easy, Fast Battery Installation Traxxas engineers are always looking for ways to make Traxxas products the standard for ease of use. The new snap-lock battery hold downs speed battery installation. Press a lever to release, snap them in to lock. Securing your batteries takes just seconds and there are no clips to lose. The new configurable battery compartments are designed to easily accept either 6 or 7-cell battery packs and are scaleable to fit today’s battery technology and beyond. Precision metric hex hardware is used through the E-Maxx for easy servicing and a high-tech look.
Dual Servo Steering System Dual, waterproof, high-torque servos drive a new heavy-duty bellcrank steering system. The integrated servo saver and smooth ball bearings combine with the dual-servo muscle to deliver the most powerful and precise Maxx® steering system ever.
