2 part question... What does enabling "Naza-M mode" actually do? What is the difference in the flight modes that enables? I don't see actual definitions in the manual. Where is the "PHANTOM Pilot Training Guide" that the manual refers to? It says you shouldn't enable NAZA-M until you've completed it, but it doesn't indicate where to find it. I'm guessing the training guide teaches you basic control, etc - and NAZA-M takes the training wheels off - but I'm looking for more details on these.
