Depends, I've called it both. Generally people call mine a drone, and I'm usually pretty lazy when it comes to correcting them lol. I know some Phantom Pilots frown on the term "drone" but personally, I don't care what you call it, I just enjoy flying it and answering the dozens of questions I get when doing so.I know this is a little off topic, but what do you all tell people when they ask what it is while your out flying? A drone? A quad copter? An alien ship looking for brains?
