It just works, that's what I like, I been using my iPad Mini also, with a OTG cable, something about having such a larger screen is so much nicer than having to use my iPhone.
Here a photo of my set up from last night.
Just updated as well, will be flying during my lunch break, update ran pretty smooth and quick I just did thru the APP, the controller update was annoying of course, it would not stop beeping.
