Flywoo Firefly 20PRO 4S Frame Kit

The Flywoo Firefly 20PRO Frame Kit is the compact 2-inch platform in the Firefly series, designed for high-performance micro FPV builds with a focus on high-speed flying, racing, and aggressive freestyle. With a frame weight of just 26 g and a 105 mm wheelbase, the 20PRO provides an exceptionally compact platform for powerful 4S setups.

The 2.5 mm carbon fiber bottom plate with a reinforced front arm design provides high rigidity and durability while keeping weight to a minimum. Tool-free removable side guards protect the electronics, while protected motor wire routing helps ensure a clean and tidy build.

The Firefly 20PRO is specifically designed for modern digital FPV systems and supports DJI O4, DJI O4 Pro, Walksnail Avatar Pro, and HDZero. A vibration-damped 4-point camera mount with an adjustable camera angle from 0° to 25° allows the setup to be tailored for everything from fast freestyle flying to racing.

A particularly interesting feature is the modular concept shared with the Firefly 25MINI: the digital video system can be transferred between the two platforms via the top plate. This makes it possible, for example, to use the same HD system for both a compact 2-inch 4S performance build and a more efficient 2.5-inch build.
