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.
Consumer-grade drones are often limited as to how fast and far they can fly and how long they can stay in the air for. Typically, high-end quadcopters like the DJI Phantom 3 Pro Professional can only fly for about 25 minutes and at no more than 50mph. A German company airstier is hoping to overcome some of these restrictions by building a drone powered by a combustion engine, rather than batteries.
