About this item

Product details

This AUOSHI 390 brushed DC drive motor is designed as a replacement motor for compatible HS Series RC cars. The motor is intended for replacing a worn, damaged, or non-functional motor in a compatible RC vehicle and is suitable for routine and off-road RC driving applications. Motor Type and Construction: This product is a 390-size brushed DC motor designed for RC vehicle applications. It features a metal motor housing that helps dissipate heat generated during operation. The brushed motor design uses physical brushes and a commutator to transfer electrical power to the motor windings. Pre-Installed Pinion Gear: The motor comes with a pinion gear already installed on the motor shaft, reducing the need for separate gear installation during replacement. The included gear is intended for use with compatible RC drivetrain components. Application: This motor is designed for compatible HS Series RC cars that use a 390-size brushed motor with a matching pinion gear and drivetrain configuration. It can be used as a replacement for an original motor that is worn, damaged, or no longer operating properly. Compatibility: Compatibility depends on the specific RC car model and drivetrain configuration. Before purchasing, verify your RC car model, original motor size and type, operating voltage, motor mounting dimensions, shaft configuration, pinion gear specifications, connector or wiring configuration, and available installation space. Installation: Remove the original motor and compare its physical dimensions, mounting points, shaft position, wiring, and pinion gear with this replacement before installation. The motor should only be connected to an ESC or power system compatible with its electrical specifications. Do not modify the motor or drivetrain to force compatibility. Important: This is a replacement aftermarket motor and is not an official or OEM part unless specifically stated. Actual motor performance may vary depending on the RC car, battery, ESC, gearing, terrain, load, and driving conditions.

I've used the product a few times, I like it. The product is well made. I decided to remove the lights, so the battery last longer, even though the battery charge does last quite awhile. It comes with a second battery which is great.
