SUB250 0702 27000KV Brushless Motor for 1S Micro FPV Drones – Compatible with 1.2"/1.4"/1.6" Propellers

Overview

The SUB250 0702 27000KV motor is engineered for ultra-lightweight 1S micro FPV drones, delivering extreme responsiveness and power in a compact form. With a dry weight of just 1.6g, this motor is ideal for 65mm whoops and sub-100g builds. Featuring a high 27000KV rating, it delivers strong thrust with great efficiency for tight indoor freestyle or high-speed racing.

This motor uses a 9N12P stator structure, 28AWG cables (31mm length), and a 7mm mounting shaft diameter with a 2mm shaft length, making it compatible with popular props such as 1.2”, 1.4”, and 1.6” tri-blades. Precise bearings (1mm outer / 1.5mm medial) ensure low friction and smooth operation, while the included test data proves its reliability across multiple prop configurations.
