Flywoo Firefly 25MINI O4 Wide is built as a 2.5" drone with digital transmission of DJI O4 with Flywoo Wide modification, where the original camera lens is replaced with another one with larger FOV. The drone is equipped with an external ELRS receiver on the frequency of 2.4GHz. Flywoo Firefly 25 is suitable for smooth cinematic flying, freestyle in the garden, and smaller long-range flights.
Flight control is managed by an AIO board Flywoo GOKU F405 SE 20A with an STM32F405 processor and integrated 20A regulators. All peripherals (GPS, RC receiver, video transmitter) connect via connectors without the need for soldering. The board also has an integrated buzzer for easy locating of the drone in the field. Propulsion is provided by ROBO 1303 6000Kv motors with 2520-3 propellers. The maximum speed is around 95 km/h with a 3S battery.
The frame features a bottom plate with arms made of one piece of carbon with a thickness of 2.5mm. Removable side panels protect the electronics from dirt. The top plate includes a mount for both the camera and the DJI O4 Pro unit. With 4 screws, the top plate with the FPV unit can be removed and transferred to the Firefly 20Pro drone. The FPV camera is mounted via rubber softmounts with an adjustable angle of 0°–25°.
The recommended battery is a 3S LiPo with a capacity of 450–1000mAh and an XT30 connector.
