I've had my X-Star Premium about 6 weeks now and have occasionally checked out this forum. I think it's time I came out from the shadows. I'm flying an XSP (white) with an iPad Mini 4 which I bought specifically for this purpose. I started out with my iPhone 6 but it was too small and my wife's iPad Air is too big and heavy to suit me. I did a little research and was tempted to get a Nividia K1 but in the end I figured I'd get more all around use from the iPad. What I love about my X-Star: (1) It always comes home. (2) Its so stable. (3) Customer service. I have contacted them twice once by phone once by chat. Both times I got an immediate response. What could be improved: (1) I don't like that it goes into Go Home mode at 25% battery and I can't get out of it. I suggested to Autel that they have an override in Advanced Settings to switch to a warning at 25% and periodically thereafter.
