XeRun V10 13.5T 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.
