What is the difference between a drone / quadrocopter and RC Aircraft? I'm asking definition, not fixed wing vs. multi rotor. Also wonder how many hobby/modeler flying fields operate within five miles of an airport. My point is, we've (us Phantom Pilots) are getting a bad rap for aledgely flying close to airports. Yet the modeler fields will fly jets, giant, heli and no problems. But you throw four blades on something with a camera and changes everything.
