Quadcopter 101

Multicopters, drones, quadcopters.  These little aircraft are all a new breed of radio control (RC) fun that are rapidly gaining in popularity.  But with newness, there is limited  information available on these systems.  This is particularly true for newcomers who wish to participate, but do not understand how to get started.  But first be forewarned, this is a very addicting hobby.  Once you start... eh, you'll find out.
