First, GREAT find! Second, BEST VIDEO ON THE AIR YET!
The DJI touches on a lot of additions in the Air that others have failed to see (including myself). For example, the Air will switch to camera positioning if the compass is not working correctly. When flown inside (which I've always said is an advanced flight) the _two_ downward cameras allow the Air to be much more precises.
Yet another reason why the Air does not use Occusync... it just could not fit into the smaller size.
I've also used the Air a few times but, for me, Active Track seem greatly improved. I think everything moving forward will focus on tracking a subject.
