Currently, Multirotor drones are very common and widely used for recreational and professional industrial purposes. It is widely used due to the advantages of multiple rotors.

1. Easy to control and operate. Multirotor drones are simple in structure. It is easy to control or operate, suitable for drone beginners.

2. Suitable for a variety of environmental operations. The highly maneuverable Multirotor drones are capable of hovering in the air and taking off or landing vertically. It can take off and land in a narrow space, suitable for a variety of environmental operations. It is very suitable for photography and videography.

3. Lower cost. Multirotor drones don't have many complicated accessories, so they are cheaper to manufacture and maintain than other drones.

4. It is convenient for drone operators. Multirotor drones are usually small in size, flexible and portable, bringing infinite convenience to drone operators.

However, drones have more than advantages. Let's take a look at the disadvantages of multi-rotor drones:

1. The flight time is short. Most multi-rotor drones are powered by batteries, but with current technology, batteries have limited capacity. Therefore, the speed and endurance of drones are limited. Multi-rotor drones have to turn around when they run out of battery on long flights to complete their mission.

2. Cannot work in harsh environment. Because multi-rotor UAVs can only take off and land horizontally and are small in size, their payloads are usually relatively lower than other UAVs, which makes them less capable of working in certain harsh environments.
