HappyModel CrazyBee F4 Pro V3 AIO Whoop Flight Controller For Larva, Sailfly, Mobula – FRSKY

This is the FrSky RX equipped version.

The CrazyBee series just got a little crazier! These AIO whoop style FCs are meant as replacements and upgrades for several HappyModel BnF/PnP quads, like the Mobula7, SailyFly, and Larva but are just as at home in your custom whoop/toothpick builds.

“V3.0 supports 2S – 4S LiPo, ESC upgraded to 10A. A few things have gone back to how it was before due to the lack of space: no longer using plastic connector for VTX and camera, just solder pads now; And bind and boot buttons reverted back to the original tiny ones”
