Just got my P2 and hooked it up to my Mac to do updates. Everything was up to the latest version. Then hooked up the tx. Current version is 184.108.40.206 and the latest is 220.127.116.11. So I hit upgrade and was ready to install. But in the notes, it states (in bold red) that P2 zenmuse owners should follow the instructions noted below. Step 1 was to update to version 18.104.22.168 then calibrate etc, etc. so should I not upgrade to version 12? Or are the notes incorrect? Also, I went ahead and switched to Nazam mode even though this is my 1st phantom. I've read a lot about the system and think I understand it and really want IOC mode. I think HL is a good option if I get disoriented. It warns against it if course, but I should be ok as long as I keep it in GPS and avoid ATTI for a while, right? Anything else I need to do in the software before I fly? Obviously i know about compass calibration. But I got no owners manual with it. Only a quick start. I have downloaded the users manual from the DJI site though. But do they really not ship a manual with it? Sorry for the long post. Thanks.
