All, I have purchased a few Saitek products with no issue. However I have an issue with my latest purchase, the yoke and throttle quadrant. The yoke seems to work fine, but the throttle quadrant (prop and mix also) goes from 0 to 16k with no range in between. I deleted all my joystick and axes assignments in FSX, but this issue remains. The calibration in Windows works perfectly with full range of motion. I'm really stumped on this one. Can anyone provide some input as to how I can fix this?
