Drones, Drone, and Drones

So when is a drone a drone? And an RC helicopter an RC helicopter? We have been hearing a lot about drones lately and I keep wondering if people are mixing up drones with RC flying helicopters and planes. So I searched on the Internet to see if there was any established definition of what a drone was. You see, I had always thought of a drone as being a large military or commercial industry oriented flying device that did not house a pilot and was controlled on the ground by a sophisticated computer and could fly outside of the operator’s line of sight like a large airplane or helicopter. But the article I found on arstechnica.com referred to a small flying device that did have a limited distance as being a drone. Check out this fun article and watch the video they put together, it is actually quite interesting if you love technology and cool toys of tech. http://arstechnica.com/gadgets/2014/06/flying-and-crashing-a-1300-quadcopter-drone/ So is a drone a design style or something defined by technological abilities? So I checked Wikipedia to get an idea of what the basic parameters are and here is what I discovered. There were three categories for this type of usage of the word. The first one that I thought was the definition was basically described as thus… “An unmanned combat air vehicle (UCAV), also known as a combat drone or drone, is an unmanned aerial vehicle (UAV) that is usually armed. Aircraft of this type have no onboard human pilot. Drones are usually under real-time human control, with "the human's role in UCAV system [varying] according to levels of autonomy of UCAV and data communication requirement[s]" The modern military drone as known today
