Rudder neutral value shifts from 0 to values 50-1200

[drskyking]

even after calibrating my CH USB rudder pedals. I have had this problem since I installed FS9 on my Dell Dimension. I just reformatted my hard drive, reinstalled FS2004, recalibrated my rudder pedals, reset the settings in my registered FSUIPC 3.5 and still within minutes of calibrating and resetting the neutral value of my pedals to 0 they drift. This makes aircraft very unsteady to taxi and keep straight in flight without AP. Is there a setting I can change somewhere?

This is my current FSUIPC config file:

Thank you.. Robert

Hi Robert,

I assume the hardware is OK and the controls are properly calibrated in windows game controller? Then go into FS menu and set sensitivity to max and null zone to min. Only then try to finetune the calibration in FSUIPC. From your ini file I see that the centre dead zones for all controls are set to zero, that means no dead zone at all. This way a slight noise or jitter on the joystick input will already give control movements and thus make the plane unstable.

Calibrate again and make sure you set up a proper dead zone at each controls centre. The rudder entry for instance should then read something like

Rudder=-16380,-512,512,16380.

Regards,

Frank

It also would not hurt to try turning on spike filtering for all your USB controls especially if these problems came about with a computer change. USB controls are subject to this kind of noise that can vary among computer types.

Thanks I will try that.
