Xerun Axe R3 ESC & 3300Kv 550L R2 Brushless Motor Combo - HWI38020389

Take absolute control of your trail rig with the smooth power delivery and high torque of the Hobbywing Xerun Axe R3 crawler system.

The Hobbywing Xerun Axe R3 system brings advanced Field Oriented Control (FOC) technology to your 1/10 scale rock crawler or trail truck. By combining the Axe R3 ESC with the 3300Kv 550L R2 motor, this brushless combo delivers unmatched low speed control, automatic drag brake adjustment, and incredible torque. It is engineered to sense exactly what your rig is doing on the rocks, adjusting power output dynamically to maintain a consistent speed regardless of the obstacle.

Whether you are crawling steep vertical rock faces or blasting through open trails, this waterproof system handles 2S to 3S LiPo power with ease. The integrated Bluetooth allows you to tune throttle curves, drag brakes, and performance parameters directly from your mobile device without needing an external programming card.
