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.
