small tablets fit the mavic controller so this shouldn't be any different , if you watched the unveiling on youtube they were using a crystalsky monitor with it
I'm seeing it expands like a Mavic Pro's RC, but it looks like the grips may be a little shorter. Personally, I use a Skyreat tablet holder for my MP for use with my iPad mini 4. If I ever got a Mavic Air, I'd just use the Skyreat tablet holder with it since regular size phone devices fitting into these RCs are just too little for me.
