I as see it certain definitions are getting a little mixed up. Drones are being called multi rotors, multi rotors are getting called UAV's etc.

I would classify it thus...
A drone is a radio controlled air vehicle consisting of a fixed or rotary wing attached to a fashioned fuselage (containing the radio and propulsion equipment) and having a working fixed or rotary tail piece.

A multicoptor is a radio controlled air vehicle consisting of a body to which all the rotors are attached. The vehicle can be controlled with radio system, gps, return to home or any combination of them.

Badly flown multicoptors seem to be the fly in the ointment

I'm sure I've upset someone. Though, this is not hard with the feeling running so high.
