Flywoo Firefly 20PRO 4S O4 Pro Micro Drone
Flywoo Firefly 20PRO 4S O4 PRO Micro Drone
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.
Distinct Power. Infinite Ways to Rip.
Factory pre-tuned PIDs. Locked-in feel right out of the box. Zero prop wash.
3S Power / 2.5" Props
Firefly 25MINI
The ultimate cinematic cruiser. The wider wheelbase and efficient 3S powertrain shatter the micro drone flight time barrier. Enjoy buttery smooth lines and rock-solid wind resistance.
4S Power / 2" Props
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.
Purpose-Built Details. Pure FPV.
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.
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.
Product Description
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.
Product Highlights
Seamless VTX swap between two drones, no re-soldering or calibration
Factory pre-tuned PID, 120km/h max speed, no prop wash
High-strength carbon fiber frame, reinforced front arm for crash resistance
Built-in buzzer, one-click trigger to find lost drone easily
Solder-free VTX+Buzzer+RX+GPS, plug-and-play, easy for beginners
Shock-absorbing gimbal ：0°–25° adjustable lens angle; eliminates vibration and jelly effect for stable, clear footage.
