The Hobbywing XR10 Justock G3 ESC Combo with Justock G2.1 17.5T Motor (HW38020321) is engineered for zero‑timing spec racing. The timing system is permanently set to zero degrees to deliver consistent performance for fair competition, pairing the XR10 Justock G3 ESC with the Hobbywing Justock G2.1 sensored motor.
Reliable hardware and advanced software provide strong, linear power with built‑in overload protection. The XR10 Justock G3 also features an RPM speed limit function with up to six selectable limits to suit different race regulations. Designed for 2S LiPo use, the ESC supports sensored or sensorless operation and includes a high‑efficiency thermal design with a 25mm fan.
The Justock G2.1 17.5T motor features a heat‑resistant magnet mounted to an aluminium case, double‑insulated windings, precision bearings and a robust rotor for smooth, durable performance. A built‑in Hall sensor and non‑adjustable end bell ensure fixed timing, while the silicone O‑ring helps conduct heat to the case and keep dust from the sensor. The case design supports routine cleaning and maintenance.

The Justock G2.1 motor has a heat-resistant magnet attached to the aluminium case, double insulated windings, high precision bearings and a rotor with a strong structure which guarantees outstanding performance and increased durability. The built-in hall sensor and non-adjustable end bell combined with the high precision balanced rotor guarantees a smooth linear power delivery.
The silicon 'o'-ring seal fitted between the end bell and stator helps to conduct inner heat to the motor case and prevent dust from entering the hall sensor. The case is designed for daily cleaning and maintenance which can prolong the service life of the motor and improve its operating efficiency.
This motor is perfectly matched with the XR10-Justock ESC for all zero timing spec racing and also compatible with other Hobbywing Electronic Speed Controllers.
