Hi everyone 1. If your using ground station app to run a route of some waypoints and then come back home, does the phantom need communication with the controller/wifi unit or is the programmed route stored in the phantom. I hope that makes sense. 2. If your flying in GPS mode and you switch to Atti mode and then back to GPS mode what happens with the satellites? does it have to reaquire all of the satellites over again or was it still connected to them when you switched to Atti and it just didn't use them so they would be instantly available when switched back on? again I hope this makes sense. I have many more questions but this site and a few other searches answered all of them except for these 2. so if they have been answered elsewhere a million times I am sorry for not finding those posts. thanks for any information you can provide.
