iPad mini 4 ?

Hello

I have Phantom 4 PRO V2.0.
Device what I use is Samsung Galaxy A3 phone,
quite small screen.
I want to purchase a device where is bigger screen.
Maybe iPad mini 4 or 5 tab. Is these devices ok?
Or what tables you recommend?

Mini5. Faster processor than the 4.

I understand that the Mini 5 has a faster processor than the 4 - but it that actually required? I.E. are there lag issues with the 4?
