I'm having a hard time figuring out how to program the 3-way toggle switches. I just purchased a Phantom 2 Vision. I want to make S1 activate fail-safe mode without having to completely turn off the remote. Do they come pre-programmed from DJI already? If so, what do they do by default? Also, I want to be able to recover the craft during fail-safe mode once its returned close to home. How can I do this? Also, what is this this Naza Mode I keep hearing about? Any good tutorial videos would be appreciated. Thank You!
