Since we all know what some people are doing with flying platforms is not what we do as model airplane hobbyist, what would be the best definition of a drone to separate them from model airplanes? Mine would be: Any unmanned aircraft that operates to deliver or retrieve a physical object and or record, collect or transmit outside data. Where are the loopholes and snags in this definition? I can see one in a model airplane that drops dummy ordinance for show,or taping your Go Pro camera to your canopy. I say "outside data" to exclude operation signal and telemetry. It seems we are lumped in with the drones to some extent already but it would be interesting to see a drone definition that hits the nail on the head and clearly separates model airplanes from drones.
