I have a P3P and have had one flight with my wife's iPad Mini 1 (I have an old iPad 2). Everything worked ok but the video feed was very laggy - so I thought with Black Friday / Cyber Monday today in the UK I would grab a new tablet. I was about to buy an iPad Air2 64gb WiFi when I remembered I had seen some posts about GPS. Apart from follow me mode, with a P3P do I need cellular (not connected / contracted) which gives me GPS, to fly???? The iPad Mini 1 does NOT have cellular and the map of where I was flying showed up.
