XeRun V10 17.5T G4R Brushless Motor - Black

The ultimate evolution of spec-class brushless racing motors.

The Hobbywing XeRun V10 G4R is built to dominate on the track. Delivering up to 7% more speed and 9% higher power output than comparable motors — and even 4% more performance than the previous V10 G4 — this motor sets a new benchmark for 1/10 stock racing.

Designed with a completely new rotor, updated stator, and improved airflow design, the G4R runs cooler, lasts longer, and delivers smooth, linear power that serious racers demand.

Performance Highlights

• +9% More Power & +7% More Speed compared to leading competitor motors.

• +4% Performance Gain over the G4 predecessor.

• 3% Lower Internal Resistance for higher efficiency and cooler operation.

• Linear Power Delivery for precise throttle control in spec racing.

Advanced Cooling & Heat Resistance

• Optimized Airflow Design – Exposed stator core and new rotor design increase cooling area by 25%+ over the G4.

• Faster Heat Dissipation – Heat is quickly transferred out of the motor for consistent performance during long mains.

• 220°C High-Temperature Wiring – Withstands extreme loads without degradation.

• Wear-Resistant Nylon Shims – Reduce operating noise and improve long-term durability.

Flexible Installation & Tuning

• Dual Sensor Ports – Cleaner, space-saving cable routing with protective plugs.

• Optional Rotor Upgrade – Personalize your motor for demanding race conditions.

• Finely Adjustable Mechanical Timing – Precise setup for every track and racing style.

• Modular, Easy-to-Maintain Design – Simple disassembly for cleaning and service.
