Hobbywing XeRun Justock G2.1 21.5T

Great Construction

The use of a heat-resistant magnet attached aluminum case and double insulated windings, high precision & strength bearings, and rotor with a strong structure guarantees outstanding performance and super durability.

Cool Look & Good Heat-dissipation

The aluminum case (different from the Justock3650 G1’s iron case) with a unique design not only creates a cool look but helps to dissipate heat.

Linear & Smooth Control

The built-in Hall sensor non-adjustable end bell combined with a high precision and balanced rotor guarantees the user a smooth and linear power on demand.

Re-buildable Design

The end bell is easy to be removed for maintenance purposes and for the replacement of common wearing parts such as rotor and sensor module (Ex bearings).

Copper Solder Tabs

Copper solder tabs with super low impedance at the load end of the motor allows users to directly solder the ESC wires onto the tabs for solid connection and simple wiring.

Compatible with XR10 Justock ESC

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 including other brands and is used in various 1/10th, 1/12th scale on-road & off-road vehicles. It is an ideal choice for Stock or Sport class racing but can also be a great choice for beginners or for the racers looking for a practice motor.
