Last evening was going to take my P4 Pro up. Gave me a firmware warning and made me update. I did that. I got a APPLE IOS update warning. I have an older IOS 11 something and am not updating the Ipad. Once firmware was done.......everything was good to launch. No warnings, no compass calibration. I do auto launch, it hovers and starts rising and going laterally. I fight with it and bring it down. **** thing tipped over while I was trying to land. Luck it was in the grass and we just got a ton of rain so propellers were digging into the mud/grass. I thought ****...I turned off Ipad, turned controller and drone off. Turned everything back on, all systems go no error messages. I do auto launch, P4 Pro launches, stops then starts to rise and go laterally. I am trying to get it to come down but it is not responding to commands. It kept rising for 4 seconds all while I had stick going down. Landed safely and did not have time to mess with drone of check settings? Any thoughts?
