Wow, some mis-information on this thread. The Ipad
Mini 2 is NOT the same as the IPad
Mini 4. Not even close. Go to the Apple site and check the specs. The Ipad
Mini 3 as was noted above is a Ipad 2 with some very minor enhancements, nothing that would make it better for flying a drone.
I've used an Ipad Mini, Ipad Mini4, Ipad Air, Ipad
Air 2, and Ipad Pro with my DJI drones (P3,
P4, Inspire, and Mavic) and there are definite performance differences between the them.
My Ipad Air is the processing equivalent of the Ipad
Mini 2. While it worked very well it did have some very minor issues. Still very useable but some things I noticed were; occasional partial screen refresh, partial green screen refresh, occasional momentary freeze, occasional lag. Nothing so bad it ever left me in a panic, just momentar. My Ipad
Mini 4, Ipad
Air2, and Ipad Pro run flawlessly. No issues what-so-ever. (GO app and firmware upgrade issues aside).
For me, when I buy/bought my DJI birds, I factored in the cost of a quality tablet whether it was Android based or an Apple product. It just so happens DJI products "seem" to work best with Apple products.
