I just returned from a trip to Hawaii. We had an 8th floor condo overlooking the whale rich Maui channel. We could see the whales from our lanai, but after going down to the ground and launching, I found it almost impossible to locate them from the air. After a couple failed attempts, I decided to havre my wife transport the MP to the lawn, then I would take off, fly, and return to her from my position on high. It worked well.
But when she picked it up after the flight, a gentleman in ofly ne of the lower condos told her that it was illegal to fly near the condo without getting permission from everyone in the building. She told him she would ask me about it.
The next day, I took it down to test if the winds were too strong. They were, at least for me. The same gent came down and intercepted me on my way back to the elevator. He informed me that I was breaking the law. I I told him that I was quite familiar with the law, and was following it. He asked to see where the camera was located, so I showed him. (Without giving the drone to him. I have read the "guy threw my drone into the ocean "post. Thanks.)
He said he felt like I was looking in every condo in the building, and that he specifically felt that he was being followed by it. I told him that I understood his concerns, but that I was not doing so. I then showed him some of the short video clips from the controller showing him what I had been doing. I told him that I had decades of flying experience, (we were both seniors) and was quite familiar with the regulations of drone flying before even buying one.
He seemed to settle down, and said "you seem to be a responsible person".
I again, told him I understood how he had misinterpreted the drones activity, and that I realized that there may well be others in the building with the same concerns. I said that I would be sensitive to their concerns, and from then on would launch from the far corner of the property (another 20 yds out.) and proceed promptly away from the building, and on return would try to avoid hovering for too long.
Short result: no more complaints. I could have quoted him "The FAA Modernization and Reform Act of 2012, Part 107, and Public Law 112-95 Sec 336, or just told him he was full of +++it +, but I don't think it would have done any more than inflame his anti drone feelings.
I think that the main things that helped were showing him what I had shot, and my age. If I had been 16 years old, he might not have been so easily appeased. But my advice to anyone facing a civilian like this is to be respectful. Then tell them you see how they would think as they do. After they retract their claws, try to educate, especially if you can show them some of what you shot.
BTW, I had several people come out, or even call down from their lanais to ask about the drone. Many more seemed to show a genuine fascination and interest than fear.
