The Birth of an Idea
William came up with the idea for his tri-copter while on vacation, relaxing on a sunny beach in southern France (seriously, no joke). He knew of similar projects, particularly quad-copter designs, but he didn't want his design to be influenced in any way by previous projects, making his stay in France the perfect opportunity to create his original concept, jotting down rough plans and designs in a simple notebook.
He started with simple drawings of a frame, modifying it repeatedly as he came up with more features and better designs, ultimately settling on his unique three-rotor layout. From there, he took to creating a flow chart for his main control loop, which is a technical term referring to what is essentially the brain of the system. It is responsible for everything from interpreting remote inputs to automated stability control.
Because William had no experience with microcontrollers or programming, creating the control loop was the most challenging part of the project, but after returning home, he was able to find some help from friendly people on various forums and IRC channels. He even managed to find a friend with experience building microcontroller-based copters.
