Traxxas TRX-4M Ford Bronco RTR 1/18 - White



Introducing TRX-4M, a new way to experience all the fun, adventure, and scale realism of the TRX-4 in a 1/18 platform. TRX-4M bridges the gap between the small crawler scene and 1/10 scale quality and performance. Oil-filled shocks, steel frame rails, and a smooth running drivetrain give it true outdoor capability over rocks and through grass and streams. The tight turning radius and precise throttle control give it fantastic indoor maneuverability.


TRX-4M is the perfect size to fit in a backpack for fun on the go. It’s small, powerful, and maneuverable so just about any space becomes an instant trail or crawling course. Whether it’s a mountain of books indoors or a rock garden in the backyard, TRX-4M is always ready for big fun and adventure.


TRX-4M is equipped to take on tough off-road terrain with grippy soft-compound tires, precision-engineered 4-link suspension geometry, and smooth oil-filled shocks. High center ground clearance, big approach angles, and low CG give the TRX-4M impressive capability everywhere it goes.


A full 45° steering angle gives TRX-4M an exceptionally tight turning radius and extreme maneuverability in small spaces where every inch counts. A heavy-duty 2065T steering servo delivers powerful steering authority, even on thick carpet.


TRX-4M’s oil-filled GTM shocks offer smooth suspension damping to keep the wheels firmly planted on uneven surfaces. The added control also keeps the body from bouncing around on rough terrain for a more realistic driving experience.


The innovative clipless body removes and installs in just seconds with no clips to lose or frustrating hook and loop tabs. Tough, highly detailed ABS bodies feature molded-in color with a deep glossy finish that won’t chip or scrape off.


TRX-4M is the truck that goes where you want to go, without boundaries or restrictions. Only Traxxas’ fully-waterproof innovation gives you the freedom to drive through wet grass, puddles, and streams that force others to turn around.


TRX-4M performs like a full-size crawler because it’s built like one. A rigid steel ladder frame virtually eliminates flex to put more power to the ground. The heavy-duty driveline soaks up the motor’s torque with ease, sending power to all four wheels through spool-equipped axles. 


TRX-4M rides on a sophisticated four-link suspension with heavy-duty linkage front and rear. Beefy front and rear axles have excellent articulation to climb over the toughest obstacles.


The all-in-one ECM-2.5™ (Electronic Control Module) incorporates all the features of an XL-5™ speed control, TQ receiver, and Pro Scale® Lighting Control Module into one sleek waterproof package. The ECM-2.5 features low voltage detection for 2s LiPo batteries and EZ-Set® one-button programming to select from three realistic driving modes. Smooth, precise control and outstanding throttle response allow drivers to navigate confined spaces and conquer the toughest technical obstacles with ease.

  • Waterprotected
  • LVD (low voltage detection)
  • Pro Scale LED functions
  • EZ-Set button
  • Powerful 6-volt BEC

Select from one of three custom-tuned drive modes using the EZ-Set button:

  • Sport Mode provides full forward and reverse speed with brakes and no automatic drag brake.
  • Trail Mode is the default mode on the TRX-4M. It is like Sport Mode but adds smooth drag braking at neutral for control on steep descents.
  • Crawl Mode applies full brakes the instant the throttle is released and allows drivers to continue through to reverse without a second push on the trigger. Crawl mode is perfect for that smooth scale look while creeping over technical terrain.

Pro Scale® Lighting Functions

Easily add accessory brake lights, reverse lights, headlights, and more by simply installing the LED light kit and plugging it into the ECM-2.5. The lighting control functions are already built in.

Titan 180-87T Reverse Rotation

The big Titan 180 motor delivers rugged, dependable, go-anywhere power no 1/24 scale can match. It lays down the torque on the rocks and cranks up the speed on the trails for all-day driving fun.

  • Low-speed torque for technical obstacles
  • Fast speed to keep pace as you walk alongside
  • Mounts securely with a fixed gear mesh that never needs adjustment
  • Mounting position shifts the weight bias forward for improved crawling dynamics


TRX-4M’s larger 1/18 size puts more rubber to the ground for exceptional off-road performance. Detailed wheels and tires are sized just right to carry TRX-4M up and over real-world obstacles with stunning scale appearance.

The Defender’s® Canyon Trail™ tires are scaled versions of standard TRX-4 rubber with aggressive lugs for dynamic traction.

The Ford® Bronco’s® BFGoodrich® Mud Terrain T/A® KM3 tires are accurate down to the smallest detail with an authentic lug pattern and raised sidewall lettering.
