I just noticed the old date of your post, but since I suspect more than a few people are having oversensitivity problems on the ground, I thought I'd add a late comment that I found helpful: Locate the appropiate aircraft.cfg file for the aircraft in question. With notepad (or your favorite editor) search for a parameter called yaw_stability. Increase its value in order to reduce the tendency of the aircraft to wander off heading (including on the ground). Start with adding .1 or .2 increaments at a time until you find a value that gives you your desired response. (It will NOT reduce rudder effectiveness, but will increase the positive stability of the yaw axis.) By the way, if your pitch axis is also doing the same, there is a pitch_stability parameter. Hope this helps someone. (Some of the FSX aircraft have very unrealistic flight models and definitely need substatial tweaking in order to get a more realistic response. It helps a lot if you've flown the aircraft in question so you can compare, of course.)
