there are some pretty sophisticated quad copters available with FPV ( read the ama mag,, they talk all about them),, FPV first person view,,
IOW, you have a camera in the plane, you watch it through mini monitors,, while you fly,,,
some of the quad copters have an autonomas "return to base " feature,, in other words, they know where they are, and where they came from,,
its VERY sophisticated stuff, for very little money,,
like Brett says,, dont laugh at these,, they could be pretty affective for some uses,, and you or I can buy one today,,
of course,, I am pretty sure they would suck to fly the hourglass with,,,,
