KEY FEATURES

Designed for FPV performance tuning

Two low-KV configurations are optimized for 12S power systems and 18 to 22 inch propellers.
A 24N28P framework, precision bearing, steel shaft, multi-strand winding, and anodized structure support reliable high-load operation.
A 30 x 30 mm four-hole M4 mounting pattern, 400 mm 14 AWG silicone leads, and an M6 propeller shaft simplify large-aircraft integration.
Verified load-test data covers 11 propeller combinations with voltage, current, thrust, power, efficiency, RPM, and throttle measurements.
