I've been working with the components showing you how to wire them together to make the quadcopter for video use, however when Christopher commented on one of my uploads, he made me realize that I never did explain the components separately explaining what each did and how to wire them in a basic layout.
If you're NEW to RC and these parts, this is a great video for you. I cover batteries, ESCs, Transmitters, Receivers, flight control boards, and motors.
