F405 2-4S AIO 20A Brushless Flight Controller (BLHeli_S) V3 has been updated the F411 chip to F405.  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). 

Bullet Point

  • Updated the F411 chip to F405, this new 20A board can handle 20A continuous current(22A burst), giving 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 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 AIO FC to build a bigger quad with this powerful FC to save weight and size.
