V10 G4-Spec Class (13.5T-21.5T)
Applications
| 13.5T, 17.5T, 21.5T | 1/10th STOCK Class Racing |
- 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°C)-resistant wire, heat(180°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.

Cautions:
To avoid short circuits, ensure that all wires and joints must be well insulated before connecting the motor to related devices.
- Never allow this product or other electronic components to come in contact with water, oil, fuel or other electro-conductive liquids. If it happens, stop the use of the product immediately and let it dry carefully.
- Read through the manuals of all power devices and chassis and ensure the power configuration is rational before using this unit.
- Never apply full throttle if the pinion gear is not mounted on, because (under the no-load circumstances) high RPMs may get the motor damaged.
- Connect all the devices carefully, you may not control the vehicle properly or encounter some unpredictable issues like damaged components if any poor connection exists.
- To avoid possible damage (result from overheating) to the product, please control the soldering time within 5 seconds when soldering the motor wires (a soldering iron with the power of at least 60W is needed).
- Stop immediate usage once the casing of the motor exceeds 100℃/212℉ as a high temperature may damage the motor and cause the rotor to demagnetize. Hobbywing recommends activating the “Motor Thermal Protection” (of the ESC).
