Flywoo Firefly 20PRO O4 Wide Micro Drone
Flywoo Firefly 20PRO & 25MINI: Flywoo's First Modular 3S-4S O4 PRO Ecosystem The Flywoo Firefly series redefines micro drone versatility with its revolutionary "One VTX, Two Frames" modular system. Engineered for pilots who demand both cinematic endurance and high-speed freestyle, this ecosystem allows you to transplant the entire DJI O4 PRO digital VTX between the 25MINI (3S Cinematic) and 20PRO (4S Performance) frames in under 3 minutes using only 4 screws—completely solder-free. While the Firefly 25MINI excels in long-range efficiency (up to 12 minutes flight time), the Firefly 20PRO is a bando-basher capable of speeds exceeding 120km/h. Equipped with a custom anti-vibration gimbal adjustable from 0° to 25°, it ensures jello-free, high-speed footage that was previously impossible for micro-class drones.

Swap Your VTX in Seconds
Just 4 screws.
Why build twice? We engineered the top plate to house the entire digital VTX and antenna system, keeping the powertrain bolted to the bottom. No re-soldering.
In under 3 minutes, transplant your Digital VTX to the other frame. Go from a 3S cinematic cruiser to a 4S bando basher effortlessly.

Firefly 20PRO
Pure adrenaline. A tight, aggressive frame packing a brutal 4S punch. Hovers at just 22% throttle and screams up to 120km/h. Instant punch-outs for tight gaps and violent acrobatics.
Built For:
- Bando bashing & high-burst racing
- High-speed tracking & chasing
- Aggressive freestyle maneuvers

Wider O4 video, built in.
Firefly 20PRO & Firefly 25MINI O4 Wide use the DJI O4 Wide Air Unit for a native 159° ultra-wide FPV view, DJI O4 digital video transmission, and 4K/60fps onboard recording from a compact micro setup.

Crash-Resistant Frame
To fly hard, you need to crash hard. Both models feature a rigid 2.5mm high-strength carbon bottom plate. We’ve implemented a unibody front-arm structure to dramatically increase bend resistance. Stop worrying about snapped arms and focus on hitting those gaps.

Snap On Protection
Equipped with custom quick-release side panels that armor up your core electronics. They provide a crucial buffer during high-speed side impacts and concrete rolls, saving your FC and VTX. Plus, they hide the wiring for a ridiculously clean look. Snap them off by hand.

Enclosed Guard, Zero Wire Damage
We've solved one of the most annoying micro drone issues: chopped motor wires. Both models come standard with custom motor wire protection tubes. Fully enclosed wiring means absolutely zero risk of prop strikes or tearing during a tumble. Less bench time, more air time.

Put the Soldering Iron Away
Powered by the newly designed FLYWOO GOKU F405 20A SE AIO. Its unique rectangular shape saves massive space, fitting perfectly into the tight micro layout.
- 100% Plug-and-Play ports for GPS, RX, and VTX
- Zero soldering required for builds or upgrades
- Integrated loud lost-drone buzzer—trigger via radio to find your quad in the tall grass

High Speed. Jello-Free.
Our custom anti-vibration gimbal mount features a high-precision dampening structure that effectively filters out high-frequency frame vibrations. The lens is adjustable from 0° to 25°, perfectly accommodating flat cinematic cruising or pitched-forward racing. Perfectly paired with O4 PRO/O4 for buttery smooth HD footage.
