One of the greatest joys of owning and flying a quad, is , for me anyway, going outside about 1 or 2 am on a clear night and flying at a good distance and watching the lights and how the quad responds to various winds and atmospheric pressure. About a week ago I was flying my "other quad",a Cheerson cx20, and accidentally flew to close to high tension lines. I was several hundred feet above it but I found from previous experiences that the cheerson cx20 is sensitive to outside influence's, like high tension lines. I hit RTE and it would come about halfway back and then circle back and repeat the process until I saw the lights flash showing me the dreaded auto land. I saw her come down approximately a quarter mile away. When I got up the next morning I flew my p3a over the area I suspected it came down in. It was over a pond and at a construction area where they are building a new house. I went to the owner and asked permission to search the area and was meet with a very angry man. No amount of apologies would calm him down. In the course of the conversation he hinted several times that he knew where my quad was. I feel sure that he has it, or worse yet, destroyed it. My question is this. If I am legal in all areas, including my FAA registration, can I force him thru legal means to return my quad? Any info or input will be welcomed. And please, no matter what you think about"the other quad", it is still one of my fleet and I would like to get it back. Thanks in advance for your help.
