RC Model Shop stocks the authentic Hobbywing XERUN V10 range, and the G3 generation represents the pinnacle of the V10 lineage. With advanced features such as high-precision Hall sensors, asymmetric bearing design and stepless adjustable mechanical timing, this motor gives you the tools to fine-tune your racing setup and extract maximum performance on any track condition.

Key Features

• Significantly Improved RPM and Torque — The G3 Stock specification motor delivers 16% higher KV rating and 4% increased torque compared to the previous V10 G2 Stock motor, translating to noticeably better acceleration and top-end performance on the track without sacrificing control or linearity.
• High-Precision Hall Sensor with Balanced Rotor — The built-in high precision Hall sensor combined with a meticulously balanced rotor guarantees remarkable linearity of throttle response, giving you the kind of predictable power delivery essential for competitive racing where consistency is crucial.
• Super Lightweight Construction — Weighing just 163 grams, the G3 motor is approximately 11-21% lighter than the previous generation V10 G2, allowing you to easily adjust the weight distribution and balance of your vehicle for optimal handling across different track conditions.
• Asymmetric Bearing Design — The front bearing is increased by 26% for improved load-carrying capacity and durability, whilst the rear bearing is reduced by 6% to minimise resistance, resulting in a motor that runs more stably and smoothly even under extreme racing conditions.
• Exceptional Heat Dissipation — The special shell design exposes the stator core to airflow for maximum cooling efficiency, and the specially machined end plates guarantee outstanding heat dissipation, keeping the motor running at optimal temperature even during extended racing sessions.
• Stepless Adjustable Mechanical Timing — Mechanical timing can be adjusted finely and smoothly from 20 to 50 degrees, with skid-proof lines at the rear end ensuring the timing remains stable after adjustment, giving you precise control over power delivery characteristics.
• Rebuildable Structure — The detachable design allows for regular cleaning and maintenance, with easy access to internal components, effectively prolonging the service life of the motor whilst maintaining peak efficiency throughout the racing season.
• High-Quality Component Materials — Features a high-performance stator core, heat-resistant pure copper wire rated to 200°C, heat-resistant rotor with strong structure also rated to 200°C, precision bearings from international top brands, and copper solder tabs with exceptional current endurance for bulletproof reliability.
• Intelligent End Plate Design — The 5.5T motor includes end plates with small holes to effectively prevent sand and dirt from ingressing into the motor during off-road use, whilst still allowing adequate heat dissipation—users can optionally purchase alternative end plates with larger holes if increased cooling is preferred.
• BRCA and EFRA Approved — This motor meets all the stringent regulations required for racing in recognised UK and European racing formats, meaning you can race with complete confidence that your setup is fully compliant with competition rules.

Technical Performance

The Hobbywing XERUN V10 5.5T Black G3 is a sensored brushless motor rated at 5900 KV, delivering maximum performance with 2S LiPo battery systems commonly used in 1/10th off-road racing. The motor produces 426 watts of maximum power output with a current draw of 115 amps at full power, requiring a suitably rated ESC. At just 163 grams, this is one of the lightest motors in its class, achieved through precision engineering and careful material selection. The motor dimensions are compact and purpose-built: 35.9mm outer diameter and 51.2mm length, with a 3.17mm shaft and 13.3mm shaft length, making it compatible with standard 540-size brushless motor mounts found on most 1/10th off-road buggies. The dual-pole design ensures smooth power delivery and efficient energy conversion, whilst the high-precision Hall sensors provide the ESC with exact rotor position data for perfect commutation. The stator core utilises premium laminations for reduced losses, and the precision-wound copper windings are optimised for the 5.5T configuration. This motor is specifically designed for Modified class racing and represents the evolution of Hobbywing's proven XERUN V10 platform, combining reliability with competitive performance.

Frequently Asked Questions

• What is the difference between the V10 G3 and the V10 G2? — The G3 generation offers 16% higher KV rating and 4% increased torque compared to the G2, meaning noticeably better acceleration and performance. The G3 is also significantly lighter, with the 5.5T version weighing 163 grams compared to the heavier G2 generation. The asymmetric bearing design in the G3 is also improved, with a 26% larger front bearing for better load-carrying capacity and a 6% smaller rear bearing for reduced friction.
• Is the Hobbywing XERUN V10 5.5T suitable for beginners? — This is a professional-grade racing motor designed for experienced competitors rather than beginners. The 5.5T configuration and high KV rating (5900) demand a quality ESC and proper setup knowledge. If you are new to brushless RC motors, you might consider a lower-KV motor designed for Stock class racing. However, if you're transitioning from Stock to Modified class racing, this is the motor you need.
• What battery does the XERUN V10 5.5T G3 need? — This motor is rated for 2S LiPo battery systems. A 2S 7.4-volt LiPo with adequate discharge rating (typically 50C or higher) is recommended. The maximum power output of 426 watts means you should pair this with a high-quality 2S battery from a reputable manufacturer to ensure consistent performance and longevity.
• What ESC do I need for this motor? — The XERUN V10 5.5T requires an ESC capable of handling the peak current draw of 115 amps. Hobbywing produces the EZRUN MAX10 ESC series designed specifically to work with this motor, or you can use any quality 3S-capable brushless ESC rated for at least 120 amps continuous current. Make sure your ESC is programmed correctly for sensored brushless motors.
• Can I adjust the mechanical timing on this motor? — Yes, the XERUN V10 G3 features stepless adjustable mechanical timing adjustable from 20 to 50 degrees. Timing adjustment is a critical tuning tool that allows you to optimise power delivery characteristics for different track conditions. The timing marks on the rear end plate keep the settings stable after adjustment.
• What makes the cooling system effective? — The special shell design exposes the stator laminations to airflow, maximising cooling efficiency. The 5.5T-8.5T version includes end plates with small holes designed for off-road use, which still provides excellent heat dissipation whilst preventing sand and dirt ingression. The asymmetric bearing design also reduces friction and heat generation in the rear bearing.
• Is this motor compliant with UK and European racing rules? — Yes, the XERUN V10 5.5T G3 is BRCA and EFRA approved, meaning it meets all the regulations for competitive racing in the UK and Europe. You can race with complete confidence that your motor setup complies with official rules.
• How much does this motor weigh? — The XERUN V10 5.5T G3 weighs just 163 grams, making it approximately 11-21% lighter than the previous generation. This lightweight construction makes it easier to tune vehicle balance and centre of gravity for optimal handling.
• Can I rebuild or service this motor myself? — Yes, the rebuildable structure allows for easy disassembly and maintenance. The detachable design means you can access internal components for cleaning, bearing replacement, or other maintenance tasks, effectively extending the service life of the motor.
• What is the shaft diameter and length? — The XERUN V10 5.5T has a 3.17mm shaft diameter (standard for 540-size motors) with a 13.3mm shaft length, making it compatible with standard motor mounts on 1/10th scale 4WD off-road buggies.
