About the Unity PRO CRAWLCORE

Waterproof Power Combo

The Furitek Unity PRO CRAWLCORE is a waterproof 2-in-1 brushless system that combines a 3500KV motor with a built-in FOC ESC. Engineered for the TRX-4M, it’s fully sealed against water and dust (IP67 equivalent), making it ideal for extreme conditions. Its compact design simplifies installation with fewer wires, offering a clean, plug-and-play upgrade.

Smooth Crawling Control

FOC (Field-Oriented Control) technology delivers whisper-quiet operation, minimal cogging, and unmatched low-speed throttle precision, critical for technical crawling. With selectable BEC outputs (5.5V / 7.4V / 8.4V @ 5A), it powers even the hungriest micro servos, while the Furicar app allows on-the-fly tuning, telemetry monitoring, and firmware updates.

Torque-Optimized Drivetrain

Paired with the upgraded MICRO STELLAR 4M Transmission, the combo features CNC-machined aluminum housing and steel gears for durability and brushless compatibility. Its 40.3:1 gear ratio enhances torque and throttle response, giving your TRX-4M unbeatable crawling finesse and reliability right out of the box.
