Very cool, and pricey.
Years ago when DSLR's came out there was a guy who used a RC helicopter with a camera on it to take pictures of properties for real estate purposes. He was doing pretty well till the FAA stopped him. They said since he was doing it in a commercial endeavor he needed their approval, which they declined. He had a great business going but big brother shut him down.
Wonder if the FAA changed their mind about this? If so it may be a good business to get into as long as you can fly a RC helicopter.
