Hobbywing's G4R platform represents a significant advancement over previous generations, with confirmed improvements in overall speed and power output. The new stator and rotor design dramatically improves performance metrics, with the 13.5T version showing 7% more speed and 9% more power under the same test loads compared to popular non-Hobbywing motors. For UK RC enthusiasts and competitors seeking genuine brushless RC motor components from an established manufacturer, the XERUN V10 G4R ecosystem provides an uncompromising foundation for competitive racing.

Key Features

• Stronger Magnetised Rotor Design — This optional rotor features enhanced magnetic properties compared to the standard rotor, delivering increased torque and power output that translates directly into faster acceleration and more aggressive performance on medium and large tracks, making it ideal for Blinky competition applications.
• Optimised for High-Traction Tracks — Specifically engineered for demanding racing environments where grip is plentiful, this rotor's characteristics make it the perfect choice for high-traction surfaces where the standard rotor might leave performance on the table.
• Patent-Designed Rotor Heat Dissipation — The rotor features an advanced heat dissipation patent design that allows air to flow directly through the motor, keeping temperatures low and maintaining consistent internal resistance even under sustained competitive racing conditions.
• 180°C High-Temperature Resistant Iron Core — The rotor core is manufactured from high-temperature resistant iron with an explosion-proof structure, engineered to withstand the extreme demands of competitive racing without degradation or failure.
• International First-Tier Brand Bearings — Features precision bearings from internationally recognised high-performance suppliers, capable of handling the harsh demands of competitive testing and racing without compromise.
• Easy Rotor Swap Capability — The modular design of the XERUN V10 G4R platform allows for simple rotor replacement, enabling racers to quickly switch between the standard and optional rotor depending on track conditions and competition rules.
• Competition-Grade Engineering — Manufactured using industry-leading materials and construction techniques, with thicker copper components ensuring lower internal resistance and greater heat capacity throughout the rotor assembly.
• Compatible with Dual Sensor Ports — The optional rotor works seamlessly with the motor's dual sensor port design, providing flexibility in sensor wire routing with included silicon port plugs for unused connections.

Technical Performance

The Hobbywing XERUN V10 G4R Optional Rotor (HW30820407) is a precision-engineered component that represents the pinnacle of brushless motor technology for 1/10 scale RC cars. This rotor is designed to work with XERUN V10 G4R motors in 13.5T and 17.5T configurations, each offering distinct performance characteristics for different racing applications. The rotor features a D12.3 diameter with a t25.2 thickness specification and D7.12 shaft interface, ensuring perfect compatibility with the G4R motor platform. The G4R motor series itself delivers exceptional performance metrics: the 13.5T variant produces 4100KV and maximum power output of 297W with a 70.7A current rating, whilst the 17.5T version offers 3150KV with 213W maximum power output and 49.4A current rating. Both versions are compatible with 1-3S LiPo battery systems, making them incredibly versatile for various racing setups across UK RC tracks. The motor housing measures 35.8mm in outer diameter with a 51.3mm length and 3.175mm shaft diameter, weighing just 152g for the standard configuration. Internally, the rotor utilises the highest temperature-rated enamelling wire available at 220°C, providing superior heat resistance compared to competitor products whilst improving overall motor efficiency. The G4R platform incorporates an open core can design with the new rotor, allowing direct cooling of the stator heat through airflow whilst the rotor's patent-designed heat dissipation structure maximises cooling efficiency even during sustained high-power racing sessions. Low internal resistance—approximately lower than the G4 generation—combined with high efficiency design means temperature rise remains minimal even under demanding competitive conditions. For UK racers requiring genuine Hobbywing brushless motor components backed by comprehensive engineering, the XERUN V10 G4R rotor represents an investment in proven performance technology.
