Re: What is a drone?
Some people (including me) are of the notion that the term "drone" refers to an autonomous craft which utilises a GPS receiver whilst flying so it can without user interaction hold its position, do waypoint missions, return to launch point and avoid obstacles with the use of proximity sensors, which makes it easy for any newbie to pick up and try to fly and quickly get into trouble if they're not careful - aka just about all of the DJI range
But "quad"/"quadcopter"/"multirotor" is what more describes FPV (first person viewing) racing/freestyle quadcopters where the user has to be in full control all the time as there's no autonomy involved beyond the craft using a gyroscope to hold its angle when you let go of the pitch & roll control - this level of flying usually requires the operator to have spent many hours practicing to get competent.
