Description

Hobbywing XERUN V10 G4R ROAR Stock Motor

Hobbywing XERUN V10 G4R targets serious 1/10 and 1/12 Stock racers who chase clean, repeatable speed. Moreover, Hobbywing built this flagship motor to pair tightly with the XR10 Stock Spec G2 ESC. As a result, you get strong efficiency plus stable power from the first lap to the last.

Engineered for the podium starts with heat control and smooth output. Therefore, the design focuses on airflow, low loss, and precise sensor feedback. In addition, the layout supports neat wiring in tight touring and pan car chassis.

Key performance features

First, cooling drives consistency in Stock racing. Consequently, this motor uses a fully exposed stator core to increase surface area and shed heat fast. Additionally, the rear opening structure pushes more airflow through the can, which helps you avoid thermal fade during long mains.

• Maximized cooling: Fully exposed stator core plus a large rear opening for stronger airflow.
• Dual sensor interfaces: Dual sensor ports support flexible routing and cleaner builds.
• Soldering-friendly design: Widened copper bars add spacing, so solder joints stay easier and more secure.
• Outstanding linearity: A high-precision Hall sensor and balanced rotor deliver smooth, predictable throttle feel.
• High-temp durability: 220°C enameled wire and strong bearings handle high current demands.

Technical notes and race optimization

Next, many ROAR Stock classes require zero timing, or Blinky mode. Accordingly, factory KV testing at zero ESC timing helps you choose a motor with confidence. Meanwhile, you should still verify rules and tech limits at your track.

• Blinky mode ready: Factory-tested KV at zero ESC timing for spec racing confidence.
• Thermal management: Monitor motor temps every run. Then allow cool-down time when temps climb.
• Pro tip: Treat Final Drive Ratio (FDR) as your main tuning tool. For example, start with the manual recommendation, then adjust in small steps as grip and temperature change.

Finally, understand why heat and gearing connect. Therefore, too much gear can spike temps and reduce punch late in the run. On the other hand, too little gear can cost straightaway speed and lap time.

For background, a sensor-based system relies on accurate rotor position feedback. In fact, Hall effect sensor operation in brushless motors explains why smooth commutation improves control. Ultimately, Hobbywing XERUN V10 G4R gives Stock racers a practical path to speed, consistency, and clean drivability.
