Hobbywing XERUN Justock 3650 SD G2.1 Sensored Brushless Motor
High-Performance Fixed-Timing Motor for 1/10 & 1/12 RC Racing
The Hobbywing XERUN Justock 3650 SD G2.1 Sensored Brushless Motor builds on the proven performance of the G2 and G1 models with a refined can design, improved cooling, and a lighter, more efficient structure. Designed specifically for zero-timing (blinky) stock racing, this motor delivers smooth, linear power and exceptional reliability for both competition and practice.
Engineered for Durability & Efficiency
Built with a heat-resistant aluminum case, double-insulated windings, high-precision bearings, and a robust rotor, the G2.1 guarantees consistent performance and long-lasting durability. A silicone O-ring seal between the stator and end bell enhances heat conduction and protects the internal Hall sensor from dust and debris.
The detachable motor structure allows for easy cleaning and maintenance, extending service life and maintaining peak operating efficiency over time.
Precision Control & Compatibility
Featuring a non-adjustable fixed-timing end bell and precision-balanced rotor, the G2.1 offers incredibly smooth throttle response and predictable power delivery. It pairs perfectly with the Hobbywing XR10 Justock ESC for zero-timing spec racing but is also compatible with other Hobbywing and third-party ESCs.
This motor meets IFMAR and ROAR specifications, making it legal for a wide range of stock and spec racing classes.
