Ignore this, the joystick had gotten out of calibration somehow. Should of been the first thing checked. My apologies.
Would like to know if it's possible to add usb rudders to RB3D

I don't think its possible to do that normally but there are programs out that emulate 2 sticks and trick the game into thinking its one.
I believe this works with rudder pedals as well.

Is a mirror of the program because the download link on that first site no longer works.
