Flywoo Firefly 20PRO O4 PRO (ELRS)
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.

Distinct Power. Infinite Ways to Rip.
Factory pre-tuned PIDs. Locked-in feel right out of the box. Zero prop wash.
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.
Built For:
-
Long-range freestyle (Up to 12 mins)
-
Cinematic FPV & scenic dive
-
Smooth indoor/outdoor cruising
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.
