Hobbywing Xerun V10 G5 25.5T Competition Stock Brushless Motor – High Torque Edition

The Xerun V10 G5 25.5T is designed for 1/10 scale Stock Class competition racing at the 25.5T specification, which is commonly used in 1/10 2WD buggy stock class, 1/10 4WD buggy stock class, and some touring car club-level stock classes. It is compatible with most popular 1/10 buggy and touring car chassis using standard 540-size motor mounts, including Kyosho RB7, Team Associated B74, TLR 22 5.0, Xray XB4, and similar platforms. Check your specific class regulations to confirm 25.5T eligibility.

The 25.5T has more windings than the 21.5T, resulting in a lower KV rating and lower RPM at the same voltage. In practical terms, the 25.5T produces less top speed but more torque at lower RPM compared to the 21.5T. The 25.5T is typically used in classes where lower power output is required for balance and control, such as 1/10 2WD buggy stock class on technical tracks. Both motors share the same G5 platform, thermal management design, and modular construction.

The Xerun V10 G5 25.5T is a sensored brushless motor compatible with any sensored brushless ESC supporting 1-2S LiPo input. For best performance in stock class competition, it pairs optimally with Hobbywing's Xerun XR10 Pro G2 or XR10 Pro Stock Spec ESCs, which are tuned to work seamlessly with the V10 G5 platform. It is also compatible with other high-quality sensored ESCs from Tekin, Reedy, and LRP. Always verify your ESC is stock class legal for your specific racing series.

The Xerun V10 G5 features an adjustable Hall sensor timing ring on the motor endbell. For the 25.5T, start with the manufacturer's recommended baseline timing position and adjust based on track conditions and ESC settings. Lower timing provides smoother, more linear throttle response suited for technical and high-traction tracks, while higher timing increases peak power for faster, more open layouts. Fine-tune in small increments and test on track. Consult the included manual or Hobbywing's official support documentation for specific timing positions.

Regular maintenance includes cleaning the motor after each race session using compressed air or a dry brush to remove dirt and debris - avoid liquid cleaners. Check and replace bearings when they show roughness or play. The modular design allows rotor removal and replacement without specialized tools. Inspect the sensor cable and connector for damage before each session. For competitive use, Hobbywing recommends periodic bearing replacement and rotor inspection to maintain consistent performance.
