Review on HGLRC Zeus F722 Flight Controller with Barometer and Black Box for DJI Racing Drones, Quadcopters and Multirotors by Candice Lohan

I've bought these flight controllers over and over again, although I could never get the first one to fly properly. After my third purchase, I saw an ad on Betaflight stating that there was a bug in the FC software. All 3 air traffic controllers are still flying like garbage.
