Flywoo Firefly 25MINI HDZero - 3S ELRS

Flywoo Firefly 25MINI is a built drone with digital transmission HDZero and 2.5" propellers. The diagonal distance between motors is 122 mm. The drone is suitable for freestyle flying. The weight without the battery is 97.5 g. Thanks to the efficient 3S power system, it offers a long flight time – with a 1000mAh battery up to 12 minutes.

The core of the drone is the AIO board Flywoo GOKU F405 SE 20A, which combines the flight controller and ESC in one. The flight controller uses the STM32F405 processor combined with the ICM42688-P gyro and 8MB memory for blackbox. The board allows the use of Betaflight or INAV firmware. The ESC handles 20 A and power from 3S LiPo - LiHV. The board features plug-and-play connectors for GPS, RC receiver, and video transmitter, allowing later modifications without soldering. The integrated loud buzzer helps locate the drone in the field.

The digital transmission is managed by the system HDZero Whoop Lite and Micro Cam . The video transmitter and antenna are located on the top board, which can be removed with just 4 screws – the same video system can thus be moved to the Firefly 20PRO frame without soldering. The camera is mounted in a vibration-damping holder with an adjustable angle ranging from 0–25°, which reduces jello effect and suits both calm cinematic and faster freestyle flying. The motors ROBO 1303 6000KV with three-bladed propellers 2520 (2.5") provide propulsion. The bottom plate of the frame is made of 2.5 mm carbon and the front arms have a reinforced single-piece construction for increased drop resistance. The side plastic panels protect the electronics and the covered tubes protect the motor cables.

The battery connects with an XT30 connector. The drone is supplied as BNF with an ELRS 2.4 GHz receiver. Recommended are 3S LiPo - LiHV batteries with a capacity of 450–1000 mAh.
