Happymodel is about to release the CrazyF411 20A AIO toothpick flight controller. This is the most powerful whoop/toothpick style flight controller released from Happymodel. It supports 2-4s battery input and provides 20A to the motors. One of the most interesting features is the integrated SPI Frsky receiver working with D8/D16 protocols. This integrated receiver has PA/LNA power amplifier and the diversity antenna. This should give more control range for this flight controller.
