Yesterday, I took the drone (Phantom 4 Pro V2+) for its maiden flight. All went well for 30 mins with multiple Take Offs and Landings, then on the last landing the propellers stopped and the ESC error codes 1 & 2 came up on the controller screen. I also got a warning to check propellers and motors which visually were all fine (even removing and reattaching the props). I have since up dated the controller and drone firmware – with no change. Please advise.
