Well, got the iPad Air 2 and be getting the P3P set up soon. Got the wifi/cellular which should help quite a bit. For software, I know Dji Go does the job well but if I were to go Autopilot or Litchi, which would be best in the long run. I noticed as well another software out there called Airnest. Is it a good complimentary addon or does one of the other programs perform close to or same function? When you do use the GPS functionality of Air 2, do you need to have it active Cellular Data ON or is the controller/Phantom just using the GPS "chip" built in the Air 2. That is, it's said you don't need to have cell service for follow me and other features but do you need to have it on (installed). Currently have it off since I don"t have any data plans selected. Went out and got an Apple Sim card for future choices for a cell carrier when it's needed. Hope you all understand my question. Looking at getting apps (iOS) such as Airnest, Autopilot or Litchi. Is Airnest to compliment Autopilot or Litchi or not needed. Debating on either getting Autopilot/Airnest or Litchi/Airnest. I read the pros and consult each but need real world opinions. Wasn't Airnest $9.99 a couple days ago? Saw it for that price got iTunes juiced up with cash and got back to it yesterday and it's 19.99.
