I am still getting to grips with my Phantom, please bare with me. Right so Reading several posts I understand that the S1 switch can be customised to have failsafe in Naza m mode. Now when I'm in my assistant software I'm currently in phantom mode, but it already shows that last position is failsafe? I have not tried it can anybody expand on this I have a phantom 2.4ghz. V2.0 by the way is this the latest version?
