The Ultimate Electric 4X4 Maxx Monster!

Now With Self Righting!*

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!

Note: The vehicle shown may not be an accurate representation of the body color/paint scheme you will receive. Paint schemes are selected randomly. The Traxxas E-Maxx model TRA39086-4 is available in four different color schemes: red, blue, black and grey-black. If you would like a specific color, please contact our customer service department prior to placing your order and we will do our best to honor your request.  

The Traxxas exclusive Self-Righting feature made its debut in the ground-breaking X-Maxx monster truck. But Traxxas didn’t limit this innovation to one truck. With one press of a button, your monster truck can automatically get itself back on all four tires. This means the action doesn’t have to stop to rescue an upside down truck.

Traxxas Stability Management
Traxxas Stability Management (TSM) allows you to experience all the extreme power, speed, and acceleration that was engineered into your E-Maxx making it much easier to control on common slippery surfaces such as dusty asphalt, smooth concrete, and even ice and snow. Punch it off the line and TSM goes to work sensing the vehicle’s direction and making steering corrections to provide straight-ahead full-throttle acceleration without fishtailing, spinouts, and loss of control. TSM also works during cornering, first making intuitive corrections to maintain your line, and then allowing you to hammer the throttle earlier in the turn for much faster exit speeds. Braking is dramatically improved as TSM works to keep you arrow straight until you come to a complete stop.

  • TSM make the vehicle easier to drive 
  • TSM works to stabilize the vehicle over rough and loose surfaces
  • TSM dramatically improves braking performance, preventing the vehicle from spinning out
  • TSM never restricts throttle (or fun!)
  • TSM assistance is fully adjustable, or can be turned off
  • TSM is fully compatible with Traxxas Link
