Flywoo GOKU GN405 Nano HD 20A Stack V3 with ELRS

The Flywoo GOKU GN405 Nano HD 20A Stack V3 combines an F405 flight controller with a 20A 4-in-1 ESC on a compact 16x16mm footprint, built for 2-inch to 3-inch micro builds and cinewhoops. A built-in TCXO ELRS receiver and a plug-and-play port for DJI O3/O4 cut down on wiring and weight.

Key features

• Plug-and-play connector for DJI O3/O4 digital air units straight off the board, with no extra wiring
• Integrated high-precision TCXO ELRS receiver saves the weight and wiring of a separate module
• Built-in barometer and 16MB blackbox for altitude hold, GPS rescue altitude and PID tuning
• 20A continuous current suits lighter micro freestyle and whoop-class motors on 2S to 4S packs
• Combined FC and ESC weigh about 7.8g, keeping sub-250g builds light
