Overview

The iFlight Defender 16 Motor is tailored for ultralight micro FPV builds, offering two high-speed versions: the 1002 14000KV and the upgraded 1103 14000KV. Both motors are optimized for 1.6-inch props like the Defender 16 1809-3 and deliver impressive thrust in sub-250g builds. Combined with the Defender 16 AIO and frame, they enable agile performance for freestyle, cruising, or cinematic flights.

Changelog (Mar 5, 2024):
The Defender 16 motor series was upgraded from the 1002 14000KV to the 1103 14000KV version, featuring higher thrust and thermal stability.
