Hi fam0612,
Just having a read of your post and I've had a few issues myself,
having overcome the problems I've had,
I would suggest that inside the FSUIPC menu there is an option to calibrate the joystick i'm sure it's labeled "joystick calibration"
inside this sub-menu you will be able to select the Max & Min range for your axis, this will be the same area that you chose to select the REV axis for the realism
once you have found the axis you want to "tune" you will want to put the lever to the Max and click on the corresponding "set" button, (one direction on your axis is - negative numbers the other positive)
once you have the axes tuned, this should overcome the problem you are having
If not let me know
Paddy
