I’m brand new to EVO, getting one only last week (trained on Phantom 4 Pro +). I don’t want to use a smartphone or tablet to fly unless I need some of the features such as tracking, waypoints etc which appear to be accessible only with a smartphone or tablet attached. My question is, apart from those special features, will any settings you set up before flight on a smartphone or tablet be remembered by the aircraft and controller if you switch everything off and then on again, without the smartphone later? I ask because I have the 12.9in iPad Pro which is really too heavy to mount (yes, I know it can be done) and because I don’t want to upgrade my old smartphone, which I use only for phone calls and texting.
