Powered flight is a matter of boring straight lines, at least outside the Star Wars universe. If all the technical details are solved, we might discover that the toy appeal just isn't as big as expected. Or are there many motorcyclists that prefer straight roads? Doing curves withhold reason (like on a big flat open surface) would be much exciting either. For SAR applications, another interesting application of the control advances from the drone market might be a powered rescue winch harness: use the line for power delivery from the helicopter mothership and as a safety fallback, but gain hugely increased agility and precision from using a local set of fans for lift instead of swinging under the helicopter as a passive pendulum load. It would make helicopter rescue from steep slopes much less risky and open up vertical walls (or even overhangs) for helicopter access.
