New mwmber here, and a newbi in the quad world. I'm ready to buy a P4 which will be my first quad. I've been all around the net trying to read up all I can about this device. I was going to use my Xiaomi MI3 phone with the controller, but at the store it would not connect even though DJI lists it as a recommended device. OK, moving on I decided I will go another route and purchase another device. I will use it exclusively for the P4. I read where the Chuwi HI8 is a good choice for a tablet to use. Anyone use this one that can comment please? I also looked at the new Chuwi HI12 but can find no info whether this one will also work. ???? I am confused about GPS needed or not in my viewing device. The Chuwi has no GPS. What exactly do I sacrifice by having no tablet GPS? Finally is there a better CHEAP Android tablet people here prefer?
