KEY FEATURES
Designed for FPV performance tuning
- A steel shaft and AL 7075 anodized housing provide a compact, impact-resistant structure for demanding 3-4 inch FPV builds.
- N52SH arc magnets, a one-piece outer rotor and single-strand winding support responsive power while controlling heat.
- An NSK precision bearing reduces high-speed noise and vibration across the 2800KV, 3300KV and 4100KV range.
- Three KV options cover efficient 4S operation and responsive 3-4S aircraft with 3-4 inch propellers.

ENGINEERING AND PERFORMANCE
Compact power built to last
Every critical component is engineered to maintain responsive performance under heat, high RPM and impact in 3-4 inch FPV aircraft.
Withstands heat
Controls heat-related power fading during sustained high-RPM operation.
Rapid response
Delivers crisp throttle response for compact 3-4 inch FPV platforms.
Critical component construction
Steel shaft
Resists bending to reduce vibration and rotor contact after impact.
AL 7075 anodized housing
Combines impact resistance with a lightweight, corrosion-resistant structure.
One-piece outer rotor
Secures the magnets 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
Supports efficient current delivery and heat control in a compact stator.
NSK precision bearing
Reduces high-speed noise and vibration while supporting service life.
