So I bought an iPad Air for my drone. I was going to buy a iPad mini 3 but then I looked at the size of screen difference and bought the air. Was I smart or not buying the air? It will only be used with the phantom 4 so I want to make sure I didn't waste my money. It's only 16 gig as I thought the drone didn't need anything bigger. Thanks for any advice as I haven't opened it yet just incase I need to return it
