Construction of Quadcopter
A quadcopter is a multirotor helicopter that is lifted and propelled by four rotors. It uses two pairs of counter-rotating propellers to generate lift and control movement. The key components of a quadcopter include the frame, four propellers, four electric motors, an electronic speed controller, batteries, a flight controller, and a radio transmitter and receiver. Quadcopters have applications in areas like 3D mapping, search and rescue operations, farming, environmental monitoring, and event photography. Their advantages include smaller rotors, reduced damage risk, easier construction, and lower costs compared to helicopters. However, their limitations include restricted battery life and potential vulnerability if hacked or taken over.

- 29. Advantages of Quadcopters Four small rotors have smaller diameter than one large helicopter rotor. Takes less damage to rotors. No need for a tail rotor which generates no lift. Easier to build four small blades compared to large one. They can traverse through difficult terrains because of their small size and there is less risk of damage too. They are significantly cheaper and the cost in fuel and maintenance is way lower than regular airplanes.
- 30. Disadvantages of Quadcopters Drones also contain limitations. For instance, they cannot communicate with civilians for more detailed intelligence. According to civilians drones are viewed as an invasion force. Battery power may be restricted and may require frequent charging. The worst scenario is when drones or a fleet of drones have been commandeered or taken control by the enemy.
