I would like to start using Naza mode on my P2V+. I have seen a few informative videos on youtube on operating the program but none of them tell me how to set up controller and phantom with PC. My questions are: 1 do I plug both controller and phantom into computer or just one or other? When I plug in just phantom to pc, and have both phantom and controller turned on, I get a message that says, "please connect controller" I am using DJI usb cord. 2. the assistant program that I have downloaded just says Phantom2. Is there a different one for p2v+? Thanks for the help!
