I was piloting my mav air from one side of my street to another at twilight. I know it wasn't the best time I was at 8 ft about to land when the battery fell critically low. the drone autopiloted to around 50 ft, which is half of what rth height should be, and flew straight into a tree which was blocking its path. it tarzaned down bouncing off branches till hit grass then bounced onto tarmac onto its back. it lay on its back till I retrieved it. my issue is that it was unresponsive to my commands when I tried to land. is this expected? if not then is dji liable? the right landing gear/antenna lost a securing piece now its all farschlumped and weird.
