Need help understanding how quadcopters work? LearningRC provides information on building and flying quadcopters. Learn what all the parts of a quadcopter are for and what their purpose is. You will also find reviews of our favorite quadcopters and drones, as well as reviews of motors, ESC's, frames, flight controllers, batteries and more. I started this website as I began to learn all about this hobby but I quickly realized that what I was learning could be useful to others, too. I am always open to comments or emails about anything you are struggling with or need help with. Let's learn together!
