Brushless Motor Hobbywing Justock G2.1 21.5T

Perfect design

The Hobbywing Justock G2.1 engine is the successor to the G2 model. It has improved response time and soldered connectors, making it ideal for racing, both in classic and racing car models. The use of a high-temperature-resistant aluminum housing with attached magnesium and double-insulated winding, high-precision and high-strength bearings, as well as a solidly constructed rotor guarantee unrivaled performance and durability.

Linearity of operation

Built-in, precise hall sensor combined with precision and combined with a precisely balanced rotor ensures smooth power delivery.

Attractive appearance and excellent heat distribution

Aluminum casing with a unique design not only looks great , but also aids in heat dissipation.

Foldable design

Silicone O-ring seal helps provide internal heat to the motor housing and prevents dust from entering the Hall effect sensor. The design of the device allows it to be disassembled for regular cleaning and maintenance of easily worn components such as the rotor and sensor module, extending the life of the motor and maintaining its efficiency.

Copper solder pads

Extremely low impedance copper solder pads allow users to solder the regulator wires directly onto the motor pads for a durable and stable connection and easy wiring.

Compatibility with the XR10 Justock regulator

The engine works perfectly with the XR10 regulator, as well as with other Hobbywing regulators, and is designed to work with a range of different on-road and off-road vehicles in the 1/10 and 1/12 scale. This is an ideal choice for the Stock and Sport racing classes, but can also be great for beginners or those looking for a training engine.
