Introduction
quadcopter also called a quadrotor helicopter or quadrotor , is essentially a flying device with 4 electric motors and propellers to power it. These devices are perfect for surveillance and filming application and come in a number of sizes according to your need. The four rotors are used to generate the uplifting thrust which carries this device. The weight is divided among the four rotors.
Two of them rotate clockwise while the other two on the other diagonal rotate anti-clockwise. The Quadcopter is also controlled by using these motor by changing the amount of power each motor is producing.

1.Propellers
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law
2.Brushless DC moter
A motor converts supplied electrical energy into mechanical energy. Among these, brushless DC motors (BLDC) feature high efficiency and excellent controllability. The BLDC motor has power-saving advantages relative to other motor types.

3. Flight controller
The flight controller (FC) is the brain of the aircraft. It’s a circuit board with a range of sensors that detect movement of the drone, as well as user commands. Using this data, it then controls the speed of the motors to make the craft move as instructed.
Its purpose is to stabilize the aircraft during flight. A command from the pilot for the multi-rotor to move forward is fed into the flight controller, which determines how to manipulate the motors accordingly.
4.ESC (electronic speed controller)
An electronic speed control or ESC is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking.
5.Receiver and transmitter
A radio receiver is the opposite of a radio transmitter. It uses an antenna to capture radio waves, processes those waves to extract only those waves that are vibrating at the desired frequency, extracts the audio signals that were added to those waves, amplifies the audio signals, and finally plays them on a speaker.
6.lipo battery
Lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte.
