 BetaFPV Whoop F4 20A V3 AIO Brushless Flight Controller 2S-4S


F405 2-4S AIO 12A Brushless Flight Controller (BLHeli_S) V3 has been updated the F411 chip to F405, which can totally handle 12A continuous current(13A burst), gives pilots a powerful flight. Highly recommended using it on Beta75X series drone, Beta85X series drone and HX100 series drone such as Beta85X V2 and Beta85X HD Digital VTX.

The 20A F405 AIO FC decreases the board thickness from 1.6mm to 1.2mm, which reduced the weight to 5.3g while improving the ability of the ESC to continuous current 20A(22A burst). Now you can build a bigger quad with powerful FC to save weight and size such as the Beta95X Digital VTX, Beta95X V2 and Beta95X V2 HD Digital VTX.

Because 12A V3 FC and 20A AIO V3 FC have unified the UART, both two boards have the same appearance, FC diagram, statue LED and way to connect the RX. 


  • Updated the F411 chip to F405, this new 12A/20A board can handle 12A/20A continuous current(13A/22A burst), gives the pilots a powerful flight. 
  • Come with 2 integrated Plug & Play Ports for both digital VTX and Rx, less solder work needed, easy to install. 
  • Completed the traditional mounting hole, more like the Toothpick type, perfectly prevent the damping pad from falling off, which is the super-easy installation in most whoop frame.
  • BETAFPV 20A/12A AIO flight controller will unify the UART, which is convenient for pilots to solder.
  • Compatible with 110X, 120X, 140X motors, pilots can use the 20A(12A) AIO FC to build a bigger quad with this powerful FC to save weight and size.
