Sorry if this isn't 3d but I didn't know where to put it. I have downloaded helisimrc and was hoping to use my dx6i with it but I don't know what I'm doing. First of all I read someplace that you can use a cable that has like a headphone jack on both side so that's what I have. I'm beginning to think I need the other end to be usb because when I plug it into either the headphone or mic jack on my laptop it does nothing? So I guess first of all I need to know if this cable I have will work and if so what do I do to set the dx6i up?
