Flywoo Firefly 20PRO 4S / 25MINI 3S DJI O4 Wide Micro Drone with ELRS 2.4GHz

Two micros, two very different moods. Choose the Firefly 20PRO for a compact 2-inch quad with a punchy 4S powertrain, or pick the Firefly 25MINI for smoother 2.5-inch cruising and longer flights on 3S. Both versions include DJI O4 Wide digital video and an ELRS 2.4GHz receiver, giving you crisp HD FPV without turning the build into a flying ladder.
The DJI O4 Wide Air Unit combines a 159° field of view, a 1/2-inch CMOS sensor and onboard recording at up to 4K/60fps. A vibration-damped camera mount with 0° to 25° angle adjustment helps keep the view clean whether you are cruising level or pointing the nose at the next gap.
Why You Want It






The 25MINI is the efficiency-focused option for cinematic lines, outdoor cruising and longer packs, while the 20PRO brings the sharper throttle response wanted for racing and aggressive freestyle. Both use a 2.5mm carbon bottom plate, reinforced front-arm structure, quick-release side panels and enclosed motor-wire tubes to protect the important bits when ambition briefly exceeds talent. Flywoo's modular design also lets the complete digital VTX and antenna assembly move between the separately available 20PRO and 25MINI frames using four screws, with no re-soldering required.

Disclaimer
*Choose the correct 20PRO or 25MINI version before ordering. A flight battery is not listed among the included items. Published speed and flight-time figures are manufacturer test results rather than a promise from the weather gods; Flywoo's flight-time table was recorded using a DJI O4 Pro setup, so results with the O4 Wide version will vary with battery, tune, flying style and conditions.
Still Here?
Pick 3S and stretch the flight, or choose 4S and compress the scenery. Either way, bind ELRS, charge the right pack and give that O4 Wide camera something worth recording.
