Hobbywing XeRun V10 G4R ROAR Sensored Brushless Motor
The XeRun V10 G4R is Hobbywing's ROAR-certified sensored brushless motor built specifically for 1/10 and 1/12 Stock racing. With a high-performance stator core, built-in high-precision Hall sensor, and precision-balanced rotor, the V10 G4R delivers the smooth, linear throttle response that competitive racing demands. The fully exposed stator-core design and large rear opening maximize airflow and heat dissipation — keeping temperatures down lap after lap.
Note: Two versions are available — the standard G4 version (IFMAR/EFRA certified) and the G4R version (ROAR certified). This listing is for the ROAR (G4R) version. Please verify your competition rules before ordering.
Key Features
- ROAR Certified – G4R version is on the ROAR certification list for 1/10 and 1/12 Stock class racing
- High-Performance Stator Core – New stator, rotor, and sensor assembly improves overall speed and power output by up to 5% vs the V10 G4 series
- Thermally Conductive Winding Epoxy – ROAR version fills coil caps with thermally conductive epoxy — running approximately 15% cooler at the same input power
- 50% Thicker Copper Windings – Lower internal resistance (~3% lower than G4) and greater heat capacity for sustained high-power output
- Fully Exposed Stator-Core Design – Open core can and all-new rotor maximize airflow for superior cooling (patented rotor heat dissipation design)
- Large Rear Opening – Further improves heat dissipation during intensive race sessions
- Built-in High-Precision Hall Sensor – Precision-balanced rotor ensures linear, smooth throttle response with no cogging
- Dual Sensor Ports – Two sensor interfaces for flexible wiring layouts; unused port protected by included silicone plug
- Widened Copper Bar Spacing – Easier wire soldering for cleaner motor builds
- 220°C High-Temperature Enameled Wire – Up to 40°C higher temperature resistance than competing motors
- Wear-Resistant Silent Gasket – Updated nylon mixed shims with ~2x improved wear resistance
- Easy Maintenance Modular Design – Designed for regular service and cleaning between race days

Which Turn Should You Choose?
- 13.5T (4100KV) – Highest power output for 1/10 Stock racing — maximum speed on large tracks
- 17.5T (3150KV) – Most popular all-round choice for 1/10 Stock racing — balanced speed and control
- 21.5T (2600KV) – Lower KV for 1/10 and 1/12 Stock class — more torque, better for technical tracks
What's Included
- XeRun V10 G4R motor with standard rotor (PN 30820450)
- Silicone plug for unused sensor port
Optional Accessories
- Optional stronger magnetized rotor (PN 30820407) — for medium/large track Blinky competitions or high-traction tracks
- Recommended ESC: Hobbywing XeRun XR10 G3
Important: This is the ROAR (G4R) version. The standard G4 version is certified for IFMAR/EFRA rules. Verify your competition's specific rules before purchasing. Rotation direction is C.C.W (Counter-Clockwise).
The V10 G4R features a fully exposed stator-core outer structure with widened copper bar spacing for easier wire soldering — clean builds, better heat dissipation.
New stator, rotor, and sensor assembly delivers up to 5% improvement in overall speed and power output, with nearly 4% higher output power compared to the V10 G4 series.
In benchmark testing, the V10 G4R 13.5T delivers 7% more speed and 9% more power compared to a comparable competitor motor under the same load conditions.
220°C high-temperature resistant enameled wire on the motor windings provides up to 40°C more heat tolerance than competing motors — critical for sustained race-pace running.
Dual sensor ports give you two wiring options for sensor cable routing — the unused port is protected by an included silicone plug to keep dirt and moisture out.
The G4R version is clearly labeled and listed on the ROAR certification list for 1/10 and 1/12 Stock class racing. The standard G4 version is certified for IFMAR/EFRA rules — check your competition rules before ordering.
The modular design allows easy disassembly of the rotor, endbell, and bearing components for regular cleaning and maintenance between race days.
The G4R motor windings use the highest temperature-rated wire available — 220°C enameled wire allows further resistance to heat while increasing overall motor efficiency. Temperature resistance is up to 40°C higher than other brands.
The G4R features dual sensor ports (x2), giving racers flexible options for sensor wire routing. The unused port is protected by the included silicone port plug.
The motor comes standard with rotor PN 30820450, suitable for most Blinky competition applications. The optional rotor PN 30820407 features a stronger magnetized rotor for medium/large track Blinky competitions or high-traction tracks.
The G4R uses a sleek modular design — front end plate, rotor, stator, sensor module, rear end plate, end cap, and screws all separate cleanly for straightforward service and cleaning. Cleaner motors last longer and run more efficiently.
The V10 G4R uses a fully serviceable modular design — rotor, stator, and sensor module can all be separated for thorough cleaning and component replacement.
Full mechanical drawing and dimensions: 35.80mm O.D., 51.30mm length, 3.175mm shaft, 6×M3 mounting holes, C.C.W rotation — fits standard 1/10 motor mounts.
The XeRun V10 G4R ROAR — Hobbywing's competition-grade sensored brushless motor for 1/10 Stock class racing, available in 13.5T, 17.5T, and 21.5T.
The open core can and all-new rotor design maximize airflow through the motor for superior cooling — Hobbywing's patented rotor heat dissipation design keeps temperatures in check at race pace.
The large rear opening structure further improves heat dissipation during intensive race sessions, working alongside the exposed stator-core design for maximum thermal management.
High-precision, high-strength front and rear bearings (D9×D4×T4 front, D8×D3×T4 rear) ensure durability and smooth rotation under race conditions.
Comes with standard rotor (PN 30820450). Optional stronger magnetized rotor (PN 30820407) is available for medium/large track Blinky competitions or high-traction track conditions.
