But with a greater energy density of fuel (gas engine powered), many fixed-wing UAVs can stay aloft for 16 hours or more. The average flight time is a couple of hours.

Multi-rotor drones have limited endurance and speed, making them unsuitable for large scale aerial mapping, long-endurance monitoring and long-distance inspection such as pipelines, roads and power lines.The ability to take multiple payloads per flight increases its operational efficiency and reduces the time taken for inspections.

It has the ability to fly much more closely to structures and buildings.Due to its increased manoeuvrability, it can move up and down on the same vertical line, back to front, side to side and rotate in its own axis.It provides better control of the aircraft during the flight.By far, quadcopters are the most popular multi-rotor drones. They are called multi-rotor because they have more than one motor, more commonly tricopters (3 rotors), quadcopters (4 rotors), hexacopters (6 rotors) and octocopters (8 rotors), among others. Multi-rotor drones are the easiest and cheapest option for getting an ‘eye in the sky.’ They also offer greater control over position and framing, and hence they are perfect for aerial photography and surveillance. Not perfect at either hovering or forward flight.Launch and recovery needs a lot of space.Here’s a rundown of the four main types of drones, their uses, their strengths and weaknesses: Drones are of different types and sizes and are used for a variety of purposes. It is essentially a flying robot this is controlled remotely or can fly autonomously with software-controlled flight plans embedded in its system that work in conjunction with sensors and a global positioning system (GPS). A drone is an unmanned aerial vehicle (UAV) or unmanned aircraft system.
