The wait is over for compact, powerful HD FPV creators. Today, July 20, 2026, iFlight officially rolls out the brand-new Defender 20 Lite X O4 2S HD, a refined micro cinewhoop built around the proven Defender series power system, factory flight tuning, and integrated DJI O4 Wide Air Unit. We designed this aircraft to break the compromise between lightweight portability, crash-friendly indoor flight, and professional-grade 4K cinematic output—pack big FPV performance into a sub-115g frame that you can toss in a bag and fly anywhere, anytime.

Ultra-Light Compliant Build

The Defender 20 Lite X features a lightweight design with a takeoff weight under 115g. Compliant with flight safety regulations, it makes everyday flying effortless.

Powered by the Defender series' proven power system and refined flight tuning, the Defender 20 Lite X delivers precise control and agile handling. Fly freely outdoors or navigate tight indoor spaces with ease while capturing immersive FPV footage. 

4K Ultra-Wide FOV with DJI O4 Wide Air Unit

159° ultra-wide lens, 4K/60fps recording up to 100Mbps bitrate. RockSteady 3.0+ stabilization plus Gyroflow support. 

Podded Camera Structure, Agile Flight, Stable Footage

Inherited from the series' proven vibration-damping camera pod design, the Defender 20 Lite X minimizes jello effects caused by vibrations. From low-altitude flights and fast maneuvers to dynamic close-up shots, it delivers smooth and stable 4K footage.

Switchable Prop Guard Design: Two Flight Styles in One Drone

One standout modular feature sets this new model apart from competing micro cinewhoops: quick-swap prop guards. The quick-release prop guards can be easily detached with four screws in 30 seconds, allowing to switch between prop guards and an open-prop form with ease. Fly your own style.

Prop Guards On Mode: Extra protection for indoor practice and campsite flying, reducing the risk of collisions.

Prop Guards Off Mode: Fly free outdoors and unlock your full freestyle potential.

Flexible Battery Options

The Defender 20 Lite X supports flexible battery options and features two battery mounting methods for enhanced compatibility and convenience. Carry extra batteries, fly longer. Secure quickly, swap easily.
