This is version 2 of the popular Happymodel Crazybee F4 Pro Flight Controller (CBF4 V2). This is the same F4 flight controller that is used in the Happymodel Mob7 HD Cinewhoop kit. You can now build your own cinewhoop with this FC and other components of your choice. This is also a good flight controller if you're looking to build a 65mm toothpick-style micro drone like the AirBlade Creampuff Lite or the Kabab FPV Toothpick frame. Pair this with 1103 motors like the AirBlade AB 1103 8000kV or AB 1103 10000kV

In version 2, Happymodel has incorporated feedback from pilots to make this flight controller 3S capable. The biggest changes are 

  • V2.0 could handle 1-3s Lipo/LiHV while V1.0 could handle only 1-2s Lipo/LiHV
  • V2.0 use bigger bind and boot button , change the BAT/GND pad to “through hole”
