This is video from my first flight with the new Phantom 3 Pro. I picked it up earlier today and ran it through its paces. So far, it is a significant improvement from the Phantom 2 Vision +. The iOS app is the major differentiator. All the other features are in support of the app. The remote is the same as the Inspire 1 and feels much more refined. Common features can be done using hard buttons and there is less time spent pawing at the app. I am a big fan of physical buttons and not having to look at what I'm pushing.
I have (foolishly) upgraded my iPad Retina mini to beta versions of iOS 9. The DJI app isn't playing nicely with the new HD video streaming. I can't hold this against them.
