Hobbywing Platinum 4125Sl 450Kv Fixed Wing Motor

The Hobbywing Platinum 4125SL 450Kv Fixed Wing Motor (HW30416051) is a robust, high-torque brushless outrunner engineered for 6S LiPo fixed‑wing applications. With a carefully balanced 12N14P design and precision bearings, it delivers smooth, efficient power for sport and performance aircraft, while maintaining low vibration and dependable running.

Built around a high‑standard silicon steel stator and high‑temperature insulation, the 4125SL pairs durable construction with excellent electrical performance. Isolation testing to 500V AC and tight dynamic balance tolerances underscore the motor’s quality focus. A practical 6mm shaft, standardised mounting patterns and enamelled wire outputs make installation straightforward in suitably matched airframes.
