FPV flying is a subject of hot debate. Some feel that there is a lot of potential for invasion of privacy and malicious use of this technology. Therefore, don't become a target of these debates.
Some of these rules are grounded in common sense. Most are law. It's important to remember, above all else, your priorities:
Safety for the public.
Following the law.
Safety for your aircraft and camera.
Getting the shot.
Shifting your priorities out of order opens you to injuring people, property, and possibly criminal/civil consequences. Remember … every RC aircraft has a clock. They will eventually crash. By following your priorities and best practices, risk of liability/injury/loss is greatly reduced. It's not if … it's when.
