CRAWLCORE Overview

Elevate your TRX-4M to elite performance levels with the Furitek CRAWLCORE Waterproof Combo, featuring the UNITY PRO 3500KV 2-in-1 Brushless System and the upgraded MICRO STELLAR 4M Transmission. Designed for extreme crawling precision, torque, and durability, this combo delivers buttery-smooth throttle control and efficient power delivery — even in the harshest terrain.

The UNITY PRO integrates a powerful 3500KV brushless motor with a built-in FOC ESC in a single compact and fully waterproof unit. With Field-Oriented Control (FOC) technology, it provides ultra-smooth throttle response, minimal cogging, and precise low-speed control.
