(Codemash) BYOD : Build your own drone… multi-rotor quadcopter that is!

In this world of ever increasing opportunities to purchase ‘toys’ classified as ‘drones’… have you ever wanted to fly a drone? Have you ever asked yourself the question… should I buy a drone or build? This presentation will discuss why the term ‘drone’ should be most generally referred to as… ‘multi-rotor copter’ and not UAV (unmanned autonomous vehicle) or drone. This presentation will discuss the basics of how a multi-rotor works… the steps to build a multi-rotor… including details on flight controllers, frame selection, motors and props (including determining what type of multi-rotor will suite your purpose), speed controllers and batteries. There are a lot of variables… all of these details will be broken down, making the process of building your first copter a ‘flight in the park’. At the end… a flying multi-rotor copter will be air-worthy and demonstrated.
