So why do you keep bringing up "flying out of bounds on purpose, for the thrill of it"?
Because you do not need to be too "gifted" to be able to see that this is the designed purpose of that sort of a machine.
Flying way out of bounds...blatantly out of bounds to explore what is going on beyond your field of view is what these planes were designed for.
I don't care what configuration the plane has, whether it's a specially equipped Telemaster or a RTF Quadcopter, if the plane is equipped to fly beyond line of sight then you will have countless incidents of these planes getting used that way when the pilot thinks that no one is watching him.
