TRX-4M Bronco 1/18 Scale micro crawler (battery/charger included)

Big trail capability engineered into a 1/18 scale platform you can run just about anywhere.

The Traxxas TRX-4M Bronco bridges the gap between tiny indoor micro crawlers and full-blown 1/10 scale trail rigs. Sitting on a heavy-duty steel ladder frame and suspended by genuine oil-filled GTM shocks, this truck handles technical outdoor terrain with the same precision it uses to conquer a stack of books in the living room. It is built like a proper crawler, complete with solid axles, spool differentials, and triangulated 4-link geometry.

Unlike many micro rigs that rely on friction dampers and flimsy plastic chassis tubs, the TRX-4M uses a deep C-channel steel frame and smooth, damped travel to keep the tires planted. The clipless ABS body is molded in color so rock rash will not show, and it comes packed with scale details like the spare tire, door handles, and roof rack. It is fully assembled and ready to drive, including a 7.4V LiPo battery and USB fast charger.

Why You'll Love It

• Oil-Filled GTM Shocks: Proper damping means the truck articulates over rocks instead of bouncing off them, keeping the tires glued to the terrain.
• 45-Degree Steering Angle: A heavy-duty 2065T axle-mounted servo delivers massive steering throw, letting you snake through impossibly tight technical lines.
• Clipless ABS Hard Body: Authentic scale realism without the hassle of body clips, molded in color so scratches do not ruin the finish.
• Steel Ladder Frame: Thick C-channel rails run from bumper to bumper to eliminate chassis flex and lower the center of gravity.

What's Under the Hood

Power delivery comes from a forward-mounted Titan 180 87-turn brushed motor driving a single-speed transmission. The ECM-2.5 combo unit handles ESC, receiver, and lighting control, featuring three distinct drive profiles. Flip it into Crawl Mode for instant reverse and 100% hill-holding drag brake, or use Trail Mode for smooth trail cruising with a tuned neutral drag brake. Power reaches the 7mm hexes through heavy-duty center driveshafts and locked spool axles.
