B..if I were you I'd use it to "supervise" the day labor too. just park a few houses down and buzz it around. then show up bitching an hour later. Hand of God shit..
I worked for a guy like that once. Pre-quadcopter of course. He drove a non-descript Oldsmobile and he'd park on a ridge for a while with binoculars, then he'd pull up on the jobsites and give those guys hell. I did not follow his lead.
However, today the quad flights were much better. In a week or so I'll be ready to buy a better model. I will definitely expense it to my business and will definitely get use out of it for communicating to clients. One job in particular, it will pay for itself.
