Brushless Motor Surpasshobby S3115 900KV

The SurpassHobby S3115 900 KV is a well-balanced motor engineered for medium to large FPV builds, including long-range and X-Class frames. It delivers precise throttle response, stable thrust, and robust construction.

Featuring a CNC-machined aluminum housing with ventilation, this motor maintains optimal thermal performance even under heavy load. It uses high-quality NMB bearings and 0.2 mm silicon steel laminations in the stator—designed for smooth, vibration-free operation and enhanced longevity.

On 6 S LiPo, it delivers approximately 1005 W of power and sustains currents up to 40 A, providing the muscular thrust needed for camera rigs or payload-intensive flights.

Installation is straightforward with a 5 mm shaft, 19×19 mm mounting pattern (M3 screws), and weighing around 112 g, the CNC housing offers reliable durability and easy integration.
