I cannot remember exactly, but I found one and hooked it up to the DJI software on the pc. I got the log or black box files and saw earlier flights that when plotted on the map looked like a backyard. I went to that house and the mavic owner was very pleased to get it back. I did consider keeping it, but the cost of arm, props, gimbal to replace the broken ones would get me quite a ways toward a new one. He had the DJI care package so it got fixed under that.
