is it lagging or are you out of FPV range? I use a 2018 wifi only ipad and it works well. Added the Bad Elf 2200 for the gps. I'm using the ipad holder v3 anafi adapter for 9.7" ipad ... that is sold on ebay and helderhugo reviewed (its excellent, but doesn't fit with a larger case on the ipad, so I run with no case right now).
