Overview
The Surpass Hobby BAT S4315 500KV FPV brushless motor is designed for multirotor/FPV drone propulsion, combining a detachable structure for easier cleaning and improved heat dissipation with a robust M6 threaded shaft for propeller mounting.
Key Features
- M6 shaft fits most propellers; custom nuts help protect steel shaft threads
- Detachable design for easier cleaning and improved heat dissipation
- 48SH rotor with NdFeB tiles
- NMB bearings (smooth and wear-resistant)
- 220°C high-temperature-resistant single-strand copper wire
- 0.2mm silicon steel sheet (low heat generation, high efficiency)
