One of the crucial tasks in getting the quadcopter flying is programming the ESCs, or Electronic Speed Controllers.  They store a variety of parameters, not all of which I entirely understand, but all of which need to be set for each ESC.  The Turnigy Programming Card pictured above makes this process easy.  Simply connect the ESC to the card, load the settings, and repeat.  I created this little job aid as a quick reference for the appropriate settings.
