Push the boundaries of micro FPV with the Flywoo Flybee20 2S DJI O4 BNF. While it shares the ultra-compact DNA of the Flybee16, the Flybee20 utilizes larger 2-inch props (2015 2-blade) to deliver significantly increased efficiency and flight times—up to 7.5 minutes on a single pack! This is one of the smallest, lightest, and most capable HD FPV drones on the market, fully optimized for the DJI O4 Air Unit.

Cinematic 4K in Tight Spaces
The Flybee 20 is engineered for content creators and freestyle pilots who need high-definition visuals in confined areas. Equipped with the DJI O4 Air Unit, it captures stunning 1080p to 4K/60FPS video with incredible detail. The custom 3-point shock-absorbing mount isolates the camera from vibration, ensuring your footage remains buttery smooth and jello-free, even during aggressive maneuvers.
Efficiency Meets Performance
By stepping up to a 2-inch propeller size, the Flybee20 maximizes the potential of the ROBO 1003 14800KV motors. This setup provides professional-grade stability and a top speed of ~75 km/h, all while maintaining a featherlight weight of 47.6g. The reverse thrust system further enhances control, making it perfect for precise indoor lines or outdoor park flying.
Designed for the Field
Spend less time wrenching and more time flying. The Flybee 20 features a quick-swap battery compartment with tool-free TPU mounts. The secure lock-in system allows you to change between 550mAh and 750mAh packs in seconds.
