I want again thank everyone who responded. I think I failed to give complete info by not clearly state that I had a model A 1395 Ipad with the 30 pin connector.
I am beginning to understand that there is a lot more going on under the Hood with Litchi and DJI Go.
It is so much more than a simple display device and how critical it is to have a Device that is able to deal with the complexity of what we are doing with these aircraft.
After 3 weeks of rain and a snow storm here in Victoria, British Colombia I was able to try my first P3 Pro w/ DJI Waypoint Mission using my S8 Note Phone.
it only had 4 Waypoints over a 200 foot rectangle but I was nervous as hell
but it did exactly what it was supposed to do.
I have Litchi too but the AC didn't activate when I hit the Start Arrow. Im sure that it was Pilot error because the mission I saved with Litchi and loaded in DJI ran fine.
I still am not sure which Ipad or Android Device (that I can afford) is best.
I do know that I would be a lot more comfortable if I had a big enough display that I can see with .
Thanks again for all your feedback.
