Awesome video. The stabilization (gyroscopic, optical or otherwise) is genuinely impressive. Each time I see one of your drone vids, it reminds me how far technology has come. Nice to see aerial footage documenting your latest treks.
Also - good job not getting a rock or bottle thrown at your expensive drone by the more mischievous rapscallions wandering about. Just thinking that my own instinct at a young age would be to try to capture the flying thing with a net or somesuch to see how it works. Not being malicious exactly, just the carefree disregard of youth for the property of others magnified by over-abundant engineering curiosity.
Personally I think it would be really interesting to fly your drone out over the ocean as far as you can safely go from the beach before reaching the rubicon point. Might catch a whale migration at certain times of year, August possibly? Of course I'd be extra cautious about sending anything electronic over the salty moist sea air, but it would be an invigorating flight.
It's so stable, it makes me wonder about the feasibility of a compact nuclear powered hexcopter as a long duration observation platform. It could evade being shot down, which a satellite or balloon can't do, and is more maneuverable than winged drones.
