About this item

  • Perfect Fit for TRX4M:​ Specifically engineered as a direct bolt-on upgrade for the entire Traxxas TRX-4M lineup. Compatible with Bronco 97074-1, F-150 97054-1, K10 97044-1, and Defender 97064-1 1/18 scale RC crawlers. (Note: Requires separate ESC for full brushless setup)
  • Smooth Low-Speed Control:​ The trx4m motor brushless features a precision-balanced rotor that minimizes vibration and delivers exceptional low-end torque. The 3500KV rating provides superior linear response, making it easier to navigate technical obstacles and steep climbs without "jumpy" throttle input
  • Durable Aluminum Gearbox: Unlike stock plastic housings, this trx4m motor&transmission setup includes a CNC aluminum transmission case paired with high-strength metal gears (16.6:1 ratio). It ensures smooth power transfer, reduced noise, and increased durability against heavy loads and impacts on the trail
  • Easy Installation: Designed for convenience, the trx4m brushless system equipped with JST, PH 2.0, and MX2.0 connector, allowing for a plug-and-play setup. The included side plate serves as both a battery or ESC mount, simplifying your upgrades
  • Specs That Perform:​ Rated for 2-3S LiPo batteries with 25A continuous / 60A peak current. BEC output supports 6V/7.4V @2A to power your servos efficiently. Ideal for hobbyists looking to replace brushed motors or boost their crawler's top speed

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    TinyRacer has a practical selection of RC tools, batteries, and upgrade parts. I picked up several items for maintaining my crawler, and everything made my workbench setup feel much more organized.

    Olivia Parker — Denver, Colorado

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.
