Youre problem lies in the calibration of the pedals. If you're using Win XP, you just have the defaults set, and use FSUIPC to calibrate your pedals. I don't remember if Win 98 has the default option, but if so, that's what you'll use. There was a FAQ about this over @ CH's site, and that corrected my problem, but later when I had to do it again, I couldn't find the solution @ their site.
Thanks much, I will check into it. Appreciate the help.
