850KV1100KV
KEY FEATURES
Designed for FPV performance tuning
- A rugged steel shaft and AL 7075 anodized housing resist deformation and help preserve alignment after impact.
- N52SH arc magnets, a one-piece outer rotor, and single-strand winding maintain torque while controlling heat under sustained load.
- A G1-level precision bearing reduces high-speed noise and vibration for reliable operation with 8-10 inch propellers.
- Verified load-test data covers 850KV and 1100KV configurations across six propeller combinations.

ENGINEERING AND PERFORMANCE
Built for high power that lasts
Every critical component is engineered to maintain performance under heat, high RPM and impact, giving 8-10 inch FPV aircraft dependable power throughout demanding flights.
Withstands heat
Reduces heat-related power fading during sustained high-RPM and heavy-load operation.
Rapid response
Minimizes throttle lag while maintaining the low-end torque demanded by large propellers.
Critical component construction
Rugged steel shaft
Resists bending to reduce vibration and rotor contact after hard impacts.
AL 7075 anodized housing
Combines impact resistance with a lightweight and corrosion-resistant structure.
One-piece outer rotor
Secures the magnets firmly to reduce jitter and power loss under impact.
N52SH arc magnets
Retains magnetic strength at elevated temperatures to limit torque drop-off.
Single-strand winding
Lowers internal resistance and helps control excess heat under heavy load.
G1-level precision bearing
Reduces high-speed noise and vibration while supporting a longer service life.
