Introducing the Hobbywing XeRun V10 G5 13.5T Brushless Motor

The Hobbywing XeRun V10 G5 13.5T represents the latest evolution in sensored brushless motor technology for competitive RC racing. Built from the ground up with input from professional racers, the G5 delivers measurable performance improvements that translate directly to faster lap times and more consistent results on the track.
What Makes the XeRun V10 G5 Different?
Hobbywing didn't just make incremental updates with the G5—they redesigned the motor to address the specific demands of modern stock class racing. Compared to the popular V10 G4R 13.5T, the G5 delivers:
- 3.9% increase in maximum output power for stronger acceleration out of corners
- 4% improvement in heavy-load efficiency for longer runtime and cooler operation
- 13 grams lighter weight at just 138g total
- Optimized center of gravity shifted 1.4mm toward the vehicle centerline for improved handling
Advanced Cooling Technology
Heat management is critical in competitive racing, and the V10 G5 introduces several innovations:
Exposed Winding Design
The redesigned endbell exposes more of the motor windings to airflow, allowing heat to dissipate more effectively during extended runs. This keeps temperatures lower and performance more consistent throughout your race.

Patented Rotor Cooling System
Hobbywing's proprietary rotor cooling design (patent-protected) further enhances thermal management by optimizing airflow through the motor's core. The result is a motor that maintains peak performance even under the most demanding race conditions.
Performance Tuning Features
The XeRun V10 G5 gives racers unprecedented control over motor characteristics:
Adjustable Hall Timing
Fine-tune sensor timing for smoother operation and improved efficiency. The new adjustment mechanism allows precise calibration using the Hobbywing Tunalyzer, ensuring your motor runs at its absolute best.
Adjustable Hall Sensing Distance
Three different rotor-to-sensor spacing settings let you customize power delivery response and feel. This adjustability allows you to match the motor's characteristics to your driving style and track conditions.
Premium Construction Materials
The V10 G5 is built to excel in the harshest race environments:
- High-performance premium stator core for maximum magnetic efficiency
- 180°C high-temperature-rated reinforced rotor for durability under extreme conditions
- Top-tier bearings (D9×D4×T4 front, D8×D3×T4 rear) for smooth, reliable operation
- Special rotor coating providing corrosion protection and improved magnetic performance
