The other thing is most drones tend to have a kill switch so if you go out of transmission range it simply falls from the sky, the can get expensive if you loose contact too many times. To rain on your parade even further, the US Park Service has made them illegal to fly at any national park/monument.
I have a DJI Phantom. It is a lower end model. It has a compass and GPS. If it flies out of transmitter range, it automatically returns to where it was launched and lands. You can also activate this feature with the flip of a switch. It's really cool to watch.
