What happens if drone goes out of range?

The pilot will receive an alert on their remote, smart phone, or tablet. And at the same time, the drone will be attempting to get back on course. The drone does this by retracing its flight path back until it can regain the signal again. Most drones have the feature “Return To Home” (RTH).

Do all drones need a smartphone?
