Hello everyone. I just received my x-star today but haven't taken it out yet. I have a iPad mini 2 but it's in a case and I don't want to take it out just to fly. So I'm looking for a phone or tablet just for the drone. I have a old LG LS-970 (<click for specs) that is rooted with 5.something but what specs should a device have? Should it have a compass in it? And if I buy another iPad mini would a ver4 be about the same as a ver2? I hear the iPad give more options on the screen compared to the android, is that true?
