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.
