I know this has been discussed before, but I just wanted to put together a quick summary for everyone and confirm that I'm not missing any key points before deciding on which iPad model to go with. iPad Wifi -No cell data/ GPS -Cannot download maps on location -Cache/save maps ahead of time in the GO app -Cannot update RC home point on map mid flight -No follow me feature iPad Cellular -Will download maps on location (only if you have active cell service) -GPS data is active whether or not you have active cell service -Can update RC home point on map mid flight -Follow me works Are there any other differences I'm missing? I was leaning towards the cellular, but even if I get it I doubt I'll pay for the data plan for the sole purpose of having maps download on location. If I need to use the follow me feature I can always use my iPhone 6 for that flight. As far as caching maps goes, how long do they stay cached for? I downloaded some maps the other day, and it worked perfectly when I got to my location, but the next day I went to the same place and my maps were gone. I did not clear my video cache or do any app upgrades in between.
