The XeRun AXE 4987 R3 is a high-performance sensored brushless RC crawler motor designed for 1/6&1/5 large-scale RC crawlers. With an optimized motor size, powerful torque output, high-precision magnetic encoder sensor, and IP66 protection, it delivers smooth low-speed control, strong torque, and reliable performance for demanding RC crawling applications.

The XeRun AXE 4987 R3S crawler motor features a 49.5mm diameter and an 87mm can length. Compared with conventional 4990-class motors, its overall length is reduced by approximately 3mm, while power output is increased by around 8%. Under the same load conditions, the motor generates less heat, helping maintain consistent performance while providing stronger acceleration and punch.

When paired with the XeRun AXE Plus R3 ESC, the AXE 4987 R3S motor delivers incredibly smooth low-speed operation and tremendous low-end torque, providing a level of control and driving feel that far exceeds conventional sensored power system for RC crawlers.

Using the best parts high-hardness CNC aluminum housing, top-tier bearings, premium ultra-thin silicon steel laminations, 200°C high-temperature resistant enameled wire, high-toughness alloy output shaft, make for the best motor that will deliver consistent and long lasting performance.
The motor rated at IP66, you can rest assured that your rig will survive even the messiest of trails. Rain, Snow, Mud, Sand or water, the AXE 4987 R3S motor will take it.

Featuring a built-in magnetic encoder sensor, the XeRun AXE 4987 R3S RC car motor delivers 60 times higher position accuracy than conventional Hall sensors used in standard sensored brushless motors. With excellent three-phase signal consistency, it continuously provides clean and precise rotor position feedback for enhanced control and performance.
