Happymodel Diamond F4 5in1 AIO flight controller

Happymodel is continuing to release new AIO flight controllers. This time it is DiamondF4 – the lightest F4 AIO flight controller with integrated Frsky or Flysky receiver and integrated VTX. Integrated VTX can be switched from 25mw to 200mw of power output. Other features are pretty standard – F411 MCU, MPU-6000 SPI gyro, 5A (6A burst) 4in1 ESC, OSD and Current sensor, but the total weight of the 5in1 AIO FC is only 3.42 grams!

The weight is only 3.42 grams. This is the lightest whoop/toothpick FC with integrated VTX! The closest alternative is the BetaFPV 1S VTX FC with the weight of 3.92g.

In the package you will get the FC, PH2.0 battery pigtail, FPV camera connector pigtail  and the full size RX antenna.
