My P4 will arrive this afternoon. I have never flown a drone before, except for toys. So, I am asking all those experienced pilots out there: What do I do first? I know, open the box, right? LOL What I mean is, obviously open and charge the batteries. Is there a best way to learn how to fly this thing? My plan was to take it to a small 8 acre park near my home that has almost no trees, but does have some high tension wires running through it. Is there a particular technique that would be best to get the hang of flying? Anything I should avoid doing on my first or first few flights? Do I upgrade the firmware first? Not many videos out yet, is that the same method as the P3? My setup will be a Phantom 4 and using an iPad Mini 4 for the monitor.
