getting all the firmware and downloads If you have seen some of my posts its obvious that I am new. I have a Phantom 2 vision coming in next week. I got the instruction manual via moderator of this site and a big thank you to him! I have done lots of research on these and I try and find posts here that answer my questions before I post. ONe thing I could not get clear by reading posts on this board or reading the instruction manual is the downloadable content and firmware I need to get from DJI. Can someone give me a run down on this? What do I need EXACTLY to make sure I have everything and am up to date. What is Naza? why would I want it or not want it? Thanks!
