Quadcopter (Drone)

A quadcopter, or multirotor, drone, or quadrotor, is a simple flying mechanical vehicle that has four arms, and in each arm there is a motor attached to a propeller. Two of the rotors turn clockwise, while the other two turn counter clockwise. Quadcopters are aerodynamically unstable, and require a flight computer to convert your input commands into commands that change the RPMs of the propellers to produce the desired motion.When you understand quadcopter propeller design and motor thrust, you can make changes to your quadcopter such as removing the camera and installing another payload such as a Time-of-Flight or a Lidar sensor.Flying with a different payload will have an effect on the control, flight and balance of the drone. A different payload will then require different quadcopter motor thrust.
