Excellent performance, specially designed for racing; Compared with the V10 G3R motor, the KV value of the G4 motor is increased by 9.8%, the maximum output power is increased by 5%, and the internal resistance is reduced by 4%.

The innovative outer diameter structure of the fully exposed stator core maximizes the heat dissipation area and increases the direct heat dissipation area by 25.6% compared with G3R. In addition, the rear end of the motor is a big opening structure to further improve the heat dissipation effect.

Dual sensor interface design to meet various wiring/layout requirements.

The special copper bar is customized and the spacing of the copper bar is widened, which greatly facilitates the operation of soldering wire.

The built-in high precision Hall sensor combined with the high precision and balanced rotor guarantee outstanding linearity of the motor.

The motor case is designed to be easy to dismantle for maintenance purposes and for the replacement of common wearing parts.

The use of a high-performance stator core, heat(200 deg C)-resistant wire, heat(180 deg C)-resistant rotor with strong structure, world-class high precision, and high strength bearings, and copper solder tabs with super-current

It's compliant with IFMAR, ROAR, EFRA, BRCA, JMRCA rules, and certificated by RoHS, CE, FCC and etc.
