Hi All: I bought P2V Dec 24th. I love it. I've since flown to 1000 feet straight up and flown out of WiFi range several times -- each time turning off remote to get into Return to Home mode then taking over flight control with S1 switch when I see the P2V coming back. I have not connected it to my PC and I dont know what firmware it has but I'm very concerned about flyaway now after reading this forum. I guess I was just lucky before. The box has handwritten "Updated software, 10C Activated". Does anyone know what this means? What should I do from here to prevent flyaway? What is Naza mode and what is Vision mode and what are their advantages/disadvantages? Sorry I'm such a n00b, but there isn't one FAQor one source where I can go to read what to do for new owners to maintain the P2V. Thanks in advance.
