Flywoo Firefly 25MINI Drone Kit 3S (ELRS 2.4G)

The Flywoo Firefly 20PRO/25MINI series is designed as a modular micro FPV system: a shared upper unit with a digital FPV system can be swapped between two differently configured frames - the 25MINI for efficient, long-endurance flights and the 20PRO for dynamic, agile flying.

The Flywoo Firefly 20PRO/25MINI series - Compact Micro FPV Platform with a Versatile Concept

The Flywoo Firefly 20PRO/25MINI series combines an exceptionally compact design with a well-thought-out, modular concept for modern micro FPV drones. Depending on the version, the system is geared either more towards dynamic, agile flying or towards efficient, long-endurance freestyle and cinematic flights. This makes the platform a versatile foundation for different requirements and applications.

Just 4 Screws. Why build twice? The upper plate has been designed to accommodate the entire digital VTX and antenna system, while the powertrain remains securely bolted to the lower section. No resoldering required. In less than 3 minutes, the digital VTX can be transferred to the other frame, making it easy to switch from a 3S cinematic cruiser to a 4S bando basher.

The lightweight yet sturdy carbon frame, protected motor wires, and removable side panels ensure a clean and robust design. A vibration-damped camera mount with an adjustable angle supports smooth footage, while the service-friendly electronics with plug-and-play connectors simplify assembly and future modifications. This makes the Firefly 20PRO/25MINI series a flexible solution for pilots who value compact dimensions, intelligent construction, and versatile application options in a micro FPV drone.

25MINI Drone Kit

The Flywoo Firefly 25MINI Drone Kit version is the flexible choice for pilots who want to take advantage of the well-balanced 2.5-inch characteristics of the 25MINI while using their preferred digital FPV system. The 3S platform with a 122 mm wheelbase and 2.5-inch propellers is designed for smooth, efficient flights and is particularly well suited to long-endurance freestyle, cinematic footage, and relaxed cruising. As this version is supplied without a VTX, it can be ideally combined with a custom setup; suitable connection cables for O4/O4 Pro, Walksnail, and HDZero are already included in the package.
