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.
