XeRun AXE 4987 SD R3S RC Crawler Motor
XeRun AXE 4987 SD R3S
Sensored FOC Brushless Crawler Motor
High-Power Motor for
Large Scale Crawler

Designed specifically for 1/5 and 1/6 crawlers, the XeRun AXE 4987 R3S delivers unparalleled torque,

ultra smooth low speed control, and amazing drivability. Zero cogging and powerful response allow

even the most demanding large scale builds to tackle the toughest terrain.

1/5 and 1/6 Scale Rock Crawler
More Power
in the Perfect Size
Featuring a 49.5mm diameter and an 87mm can length, the AXE 4987 is 3mm shorter than 4990 motors from other manufacturers in the industry, yet produces approximately 8% more power. The result is stronger acceleration, greater efficiency, and improved overall performance.

Perfectly Matched with the
XeRun AXE Plus R3 ESC

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.

Note: The XeRun AXE Plus R3 ESC requires firmware upgrade to version V1.1.3.

Ready to Take on Any Trail Condition

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 R3S will take it.

Note: The IP66 rating protects against splashes, water exposure, and dust under normal use but is not permanent. Protective performance may decline over time due to aging.
Do not submerge the product for extended periods, as this may cause damage.
Built-in High-precision Magnetic Encoder

Featuring a built-in magnetic encoder sensor, the 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.
