Happymodel CrazyG473 V1.0 AIO 5-in-1 Flight Controller | ELRS, 5A ESC| 1S | 5.8G OpenVTX

The Happymodel CrazyG473 V1.0 AIO 5-IN-1 packs everything you need into one tiny board: a UART-based ELRS receiver, 5A ESC, and built-in 5.8G OpenVTX.

Designed for 1S only builds, this board keeps things lightweight and clean — but note, motors solder directly to the board for a super-compact setup.

 

Product Highlight’s

• All-in-one convenience: ESC, FC, RX, VTX, OSD all baked in. Cuts down wiring and weight (if you can manage the 83 g overhead).
• ELRS + OpenVTX built-in: no need for external RX or VTX modules. Great for clean builds.
• Power flexibility: up to 400 mW VTX gives you reach; low output modes help for local flying or compliance.
• Modern components: IMU is one of the newer ones (ICM42688P), STM32G473 gives you headroom vs older chips.
