Flywoo Firefly 20 Pro

Flywoo Firefly 20PRO is a small 2" frame suitable for building a fast copter with digital HD FPV transmission. The frame is fully compatible with DJI O4, O4 Pro, Walksnail, and HDZero units.

The digital video transmission including the camera is mounted on the top plate of the drone. The top plate is also compatible with the Firefly 25Mini frame, allowing the entire video transmission to be transferred between the 2" and 2.5" bottom plates after unscrewing four screws. The FPV camera is mounted in a 4-point softmount that helps filter out vibrations from the image. The camera can be adjusted at an angle of 0–25°. The side plastic covers protect the stack from dirt and can be removed without the use of tools.

The bottom plate is made of 2.5mm thick carbon and, along with the reinforced front arms, makes the frame rigid and resistant to falls. The diagonal motor spacing is 105mm and the entire frame weighs 26g. The mounting holes for the flight controller have a spacing of 20x20mm, and there are holes prepared for the video transmitter in 20x20mm and 25.5x25.5mm. Motors are mounted on 9mm M2 holes. The manufacturer recommends ROBO 1303 6000KV motors, Gemfan 2023-3 propellers, and a 4S LiHV battery.
