There are many different types of drones, and each of them is designed to fulfill specific tasks and applications.
Fixed-wing drones look like classic planes in most cases. They need a runway for takeoff and landing or utilize catapult launchers for takeoff and parachute recovery for landing. Usually, fixed-wing UAVs can stay in the air for a long period of time.
Multirotor drones (quadcopters, octocopters, hexacopters) are vertical takeoff and landing (VTOL) aerial vehicles. The biggest advantage is that such drones can hold a steady position while in the air. It makes them a better choice for urban environment operations when you need to stay close to the target.
