Flywoo Goku F405 SE 3-4S 20A AIO Flight Controller

Micro FPV enthusiasts have long struggled with tedious assembly, messy wiring, excessive soldering, and the trade-off between flight controller performance and weight.
 
Our GOKU F405 SE 3-4S 20A AIO solves all these. Designed specifically for 2-inch and 2.5-inch drones with deep compatibility for Firefly 25mini 3S and Firefly 20pro 4S, it reimagines HD FPV building and flying.
 
Powered by STM32F405 and MPU6000 gyro for responsive, butter-smooth control. Features a dedicated dual BEC for direct DJI O4 Air Unit connection on 3-4S (no extra BEC needed).
