Details

Compact motor geometry for FPV builds: Ø27×29.6mm overall size with an M5 shaft and Ø16mm mounting pattern.

Performance reference for the 2150KV and 2550KV versions, including key specs plus static thrust, power, and efficiency curves.

3050KV data for 4S setups, combining the spec list with a throttle-to-thrust and efficiency plot for quick prop selection.

High-KV 3500KV test results on 4S highlight thrust output, current draw, and efficiency across the throttle range.
