Hey guys I'm new here. I don't have a phantom yet but I am reading and watching vids all around. One question I have is why in the manual they say the NAZA is only for experienced users? I don't understand the reason. From what I understand you get new features but the basic stable flying is still available in that mode. I am thinking that switching from GPS to ATTI can be a life saver for any kind of loss of control due to GPS loss. Your input?
