Defender 20 Lite
iFlight · China · also known as iFlight Defender 20 Lite · Updated
Defender 20 Lite is a 2-inch FPV cinewhoop developed by iFlight of China, introduced on 28 March 2025. It is a palm-sized, prop-guarded quadcopter built around DJI's O4 digital video system and kept under the sub-250 g class that many regulators treat as a lighter-touch category for hobby flying.
Overview
The Defender 20 Lite sits at the small end of iFlight's cinewhoop range, alongside the larger 5-inch SH CineFlow 5. iFlight markets it as an entry point into digital-FPV cinematic flying for pilots who want DJI's O4 image quality in a frame small enough to fly indoors or in tight outdoor spaces.
The aircraft's fully enclosed propeller ducts are intended to let it brush past obstacles and fly close to people without exposed blades, a design shared across iFlight's wider "Defender" line of prop-guarded quadcopters.
Design and capabilities
The Defender 20 Lite weighs 69 g bare and has a takeoff weight of 110 g or less, built on a 125 by 125 mm frame footprint. It is powered by a custom 600 mAh 95C 2S battery with a self-discharge protection module that brings the pack down to a 3.9 V storage voltage after 72 hours of inactivity; an optional three-port USB-C adapter charges three batteries at once. iFlight's own lab tests give an unloaded hover time of 6.5 to 7.5 minutes.
Video runs through a DJI O4 Air Unit with a 1/2-inch sensor and a 117.6° field of view, recording up to 4K/60fps with built-in electronic stabilisation and Gyroflow support, backed by 23 GB of onboard storage. The live video link reaches up to 1080p at 100 fps.
