(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.

90. mean? what do the numbers
91. ’S’ number - # of cells in series
92. 3.7 volts / cell ’S’ number - # of cells in series
93. 3.7 volts / cell ’S’ number - # of cells in series 3S = 11.1 volts 4S = 14.8 volts
94. milliamp hours (mAh) - the amount of power the battery can hold 1000 mAh battery with 1000 mA load will last 1 hour 1000 mAh battery with 500 mA load will last 2 hours
95. what does the ‘C’ rating mean? ‘C’ = capacity e.g. 20C battery can discharge safely at 20 times the amount the battery can hold 20C battery (1000 mAh) = maximum sustained load of 20,000 mA maximum safe continuous discharge rate
