DJI drones can fly over 3 miles away. There are lots of caveats, depending on the radio conditions, battery, wind, line of sight and a few other factors. But as a single number around 3-4 miles (and back) is about as far as they'd go with the conditions.
Chris Anderson of drone company 3D Robotics has estimated that there are already thousands of these unmanned devices in the air, where they can generally fly below 400 feet away from populated areas with no need for a license or permit. But once you want to do more than send up an unmanned plane for your own enjoyment, things get more complicated.
