Flywoo GOKU HEX GN405 HD 20A Stack V3 with ELRS

The Flywoo GOKU HEX GN405 HD 20A Stack V3 is a highly integrated flight controller and 6-in-1 ESC combo engineered specifically for micro hexacopters. Operating on a compact 16x16mm footprint, this stack delivers up to 20A per channel to power lightweight six-motor cinematic or long-range builds like the Explorer LR Hex. The flight controller is HD-ready, featuring dual BECs and a dedicated plug-and-play connector to interface cleanly with digital VTX units such as DJI, Walksnail, or HDZero without complicated soldering.
