Hi Guys, I have just purchased a new phantom version V1.1.1 (Naza V2). I have a question regarding a double wire underneath. I have the compass cable, 2 antenna wires and then this grey and red lead with no connecter on, to be honest looks like it has just been snipped off. I asked the shop where I bought it from what is it for and I was told not to worry about it and that it was probably from an earlier version. It must be for something?.
