CH Pedals
The Control Manager for CH pedals and yokes is great. You can enter the
adjustment section where you get small graphs that allow you to tweak the
curves to set sensitivity any way you like it by moving them around,
steepening the slopes, bowing the centers, etc. I've owned a USB Yoke LE
(no mix/prop) and a set of ProPedals for several years now and they work
beautifully.

Flight models
Many FS2002 aircraft ported over to FS9 exhibit a nose heavy attitude. Some
designers suggest setting elevator trim to compensate for this. It is often
a total remake of the .cfg and .air files to tweak one properly, which is a
big job.
