I haven't flown my P4 in weeks because it's too dang hot. I installed the last firmware update and took it out for 9 minutes until the battery was low. As I landed, a strange guy pulled up and looked curious and asked how far that goes. I said it can go around 3 miles on a good day and I started to approach him thinking he was friendly and was going to talk. He immediately revved away from me and got all sketch so I backed up. He took his phone out and started looking for my address obviously. I said my address is XYZ, I'm not doing anything illegal. He was recording me and said so are you recording people? You ar huh? And then took off. This was around 8:30pm. I literally flew straight down my street block. I live on a hill/mountain so I have an excellent view and clear line of sight. I probably didn't get much more than 1/2 mile away. I live in a community that basically backs up to a wash and wide open desert but have to pass a few houses to get ther, so I really don't fly over any houses and when I rarely do its at about 350' and long enough to fly over. At about 10:30pm I get a knock on the door which wakes my 2 and 4 year old kids up. It was the police. Dude called 911 and reported me. The cop was pretty cool and said he had to just take my information down and give me a warning. He said it would be best not to fly around there again because if they got called back, they would have to wrte me up for disorderly conduct and it would be up to the prosecutor if they wanted to pursue it. I told him that it's just a case of his word against mine, what if the guy just starts calling. Also, how is he or even you going to be abl to identify a small object 300+ feet in the sky moving 20+ mph as mine? The guy claimed I was hovering over his house for 5 minutes taking pictures and video at 50' above his house. Mind you, my entire flight was not even 10 minutes, I did zero hovering, I never hover over houses, and I wasn't even cording that flight. I can't believe I was told if they get called again I am getting a ticket.
