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.

35. multi-rotor? what is a
36. fixed wing multi-rotor multi-rotor? what is a
37. even # CW and CCW multi-rotor? what is a
38. lift and torque can be altered by varying the RPM of individual propellers multi-rotor? what is a
39. lesson. how about a history
41. first rotary wing aircraft to lift itself off the ground 1907
42. vertical takeoff and landing (VTOL) 1920’s

75. frame battery bec transmitter receiver motors speed controllers flight controller
76. battery
77. mean? what do the numbers
78. 3.7 volts / cell
79. ’S’ number - # of cells in series 3.7 volts / cell
80. 3S = 11.1 volts ’S’ number - # of cells in series
81. 3S = 11.1 volts 4S = 14.8 volts ’S’ number - # of cells in series
82. 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
83. 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 mAh maximum safe continuous discharge rate
