The Crazybee F4 V3.1 Flight Controller comes pre-soldered with a Frsky SPI receiver and XT30 power wires. This flight controller is the default FC for TheFPFlea and the Happymodel Cine8 85mm Brushless CineWhoop, but great for other ultra-light micro drones that need space and weight savings.

Build your micro drone with this AIO flight controller and solve three things at once!

Just add a VTX like the Happymodel Diamond VTX and your stack is good to go!
