By your post I would take it that your using thr game port on your PC. Try going into your "control panel" and click on "game controller"(this is on windows XP,but should be simular for '98). After clicking on "game controller" see if any of the control bars move when you move the sticks on the transmiter.DON'T do any calibrations here,it's just to see if yor computer is reading the signal from the transmitter. If they are, then it's just a matter of fooling around till you get the right assignments in ClearView.I'm using my ESky transmiter and I had to go through exactly the same thing.Here's a site that will help you out using the Walkera Xtmitters in FMS.Good luck
