My drone mysteriously dropped out of the sky immediately upon selecting the RTH function on screen of the DJI Go 4 app (iPad). I contacted DJI support but they said it must have been because I hadn’t fitted the propeller properly. My argument is that it’s sprung loaded therefore how can it come off by my mistake!? I had already been flying for 5 minutes and up to 300ft before it fell. I’ve uploaded the flight log to http://www.phantomhelp.com/LogViewer/6NGV3HOG1Z9K2687NWXZ/
Any feedback and advice would be appreciated, thanks.
