KEY FEATURES

Designed for FPV performance tuning

Three KV choices cover 6S through 12S power systems for 8 to 11 inch propellers.
A 12N14P framework, three precision bearings, a steel shaft, and multi-strand winding support stable high-load operation.
The compact 39.1 mm diameter body uses a 19 x 19 mm four-hole M3 mounting pattern and 270 mm 16 AWG silicone leads.
Verified load-test data is provided for 500KV, 700KV, and 1000KV versions across eleven propeller and voltage combinations.
