Flywoo Firefly 20PRO O4 Pro - 4S ELRS

Flywoo Firefly 20PRO is a built 2" drone with digital DJI O4 Pro transmission. The drone is equipped with an external ELRS receiver on 2.4GHz. Thanks to the 4S battery, the Flywoo Firefly 20 is a fast small drone suitable for freestyle or agile flying in the garden or gym.

Flight control is handled by the AIO board Flywoo GOKU F405 SE 20A with an STM32F405 processor and integrated 20A ESCs. All peripherals (GPS, RC receiver, video transmitter) connect via connectors without soldering. The board also has an integrated buzzer for easy drone location in the field. Propulsion is provided by ROBO 1303 6000Kv motors with 2023-3 propellers. Maximum speed is around 120 km/h with a 4S battery.

The frame has a bottom plate with arms made from 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 the camera and video transmitter. With 4 screws, the top plate with the FPV unit can be removed and transferred to the Firefly 25MINI drone. The FPV camera is mounted via rubber softmounts.

Recommended battery is a 4S LiPo with a capacity of 450–750mAh and an XT30 connector.
