Traxxas TRX-4M Scale and Trail Crawler with Ford Bronco Body (1/18 4WD RTR)

Overview

The Traxxas TRX-4M Ford Bronco 1/18 4WD RTR Scale and Trail Crawler brings the performance and realism of Traxxas trail trucks into a compact platform designed for crawling adventures anywhere. Built on the TRX-4M chassis, this small-scale crawler delivers impressive climbing ability, realistic scale details, and durable engineering that mirrors the larger TRX-4 trucks.

The TRX-4M platform bridges the gap between micro crawlers and larger trail rigs. Its 1/18 scale size makes it small enough to drive indoors while still offering the capability needed for outdoor rock crawling and trail exploration. 

Under the detailed Ford Bronco body is a rugged crawler chassis featuring steel frame rails, solid axles, and a 4-link suspension system designed for excellent articulation over obstacles. Oil-filled shocks and large soft-compound tires help maintain traction on uneven terrain, making the crawler capable on rocks, dirt, and technical trails. 

The vehicle uses a Titan 180 87-turn brushed motor, engineered to provide strong torque at low speeds. This type of motor is ideal for rock crawling because it delivers smooth throttle control and reliable climbing performance. 

Electronics are handled by Traxxas’ ECM-2.5 electronic control module, which combines the ESC, receiver, and lighting controller into a compact unit. The crawler is controlled by the included TQ 2.4GHz radio system, providing reliable and responsive steering control.

The TRX-4M is fully assembled and ready to run, and the package includes a 750mAh 2-cell LiPo battery and USB charger. The battery uses Traxxas iD technology for safe and simple charging while delivering long run times suitable for trail exploration. 

Available in blue, red, black, orange, Area 51, and white, the TRX-4M Ford Bronco offers realistic scale design combined with serious crawling performance. With a sale price of $145.99, it provides a capable and highly detailed crawler that appeals to beginners and experienced RC enthusiasts alike.
