Introduction
What is Quadcopter ?!
What is Quadcopter ?!
A quadcopter or a quadrotor helicopter is a multirotor copter that is
lifted and propelled by four rotors.
A quadcopter uses 2 sets of identical fixed pitched propellers; 2
clockwise (CW) or in one direction and 2 counter-clockwise (CCW)
or opposite direction
What is Quadcopter ?!
Quadrotor’s all four rotors work together to produce upward thrust
and only 1/4 of the weight is lifted by each rotor. So less powerful
motors are used, making it cost efficient.

Components of a Quadcopter
The Frame
Components of a Quadcopter
The structure that holds or houses all the components together. They
are designed to be strong and lightweight.
WeightSize
Materials used
The Frame
It consists of 3 parts :
• The center plate where the electronics are mounted
• Four arms mounted to the center plate
• Four motor brackets connecting the motors to the end of the arms

The Frame
Frames are usually made of:
• Carbon Fiber.
• Aluminum.
• Wood/ Plywood /MDF (Medium-density fiberboard)
4 propellers, 2 “normal” CCW , 2 “pusher” CW
Components of a Quadcopter
The Propellers
They are a bit similar to normal DC motors in the way that coils and
magnets are used to drive the shaft
Components of a Quadcopter
Electric Motors
LiPo (Lithium Polymer) batteries are used because it is light. NiMH
(Nickel Metal Hydride) is also possible. Cheaper but heavier.
Components of a Quadcopter
Battery – Power Source
Controls the speed of the motor.
Motors must all spin at precise speeds to achieve accurate flight, so
that ESC is very important
Components of a Quadcopter
ESC- Electronic Speed Controller
Four channels for a basic quadcopter is required

Radio Transmitter and Receiver
The ‘brain’ of the quadcopter
Components of a Quadcopter
Flight Controller
To decide on how to control the motors.
IMU is the electronic sensor system which measures velocity,
orientation and gravitational forces of the quadcopter.

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.
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.
