I suspect that little more than a dish antenna and a spark plug is required to over-ride the radio control of these things. The use of these will piss off nearby TV users but not as much as a shotgun will piss off the police.
The cheap paparazzi "drones" are basically RC with a camera on it however
for a couple of hundred dollars it is easy to install a autopilot.
These things can follow a grid and land on their own when out of juice.
