Generally speaking, the more expensive a drone is, the longer it will be able to stay in the air and have a longer transmission signal. Consumer drones that are best for long-distance flying include the DJI Mavic 3, which has a 15-kilometer transmission range and an impressive flight time of 46 minutes. While toy drones have a much more limited transmission range and flight time. Regardless of how far you are flying a drone, it's important to keep it within sight.
