How far and high can a drone fly safely?

I want to take my drone on a long-distance flight at high altitudes. What factors should I consider to avoid losing it?

Range and altitude depend on the drone model and controller signal strength. Some drones manage 2–6 km laterally but need enough battery for the return trip.

Wind at higher altitudes can push your drone off course. Make sure the return-to-home feature is set up accurately.
