Flying Carenado Citation 550 in FSX. Using FSUIPC to calibrate all the controllers/switches (nothing enabled in FSX). All worked well till I had to uninstall/reinstall FSUIPC in order to calibrate PFC throttles. Using Saitek Combat Rudder pedals with no issues. Aircraft when trimmed out/wings level will literally turn on its own to the left at about 2 degrees/sec. With autopilot on aircraft is in a constant 5 degree bank to the right in order to hold heading.
I've calibrated and re-calibrated the rudder pedals and all looks normal. It feels like the aircraft is flying bent. All the payload and fuel are well within CG tolerances.
I've flown fighters and other jets in the real world and we hardly touch the rudders, except for ground steering with nose wheel enabled or to align the gun on a gun run.
I believe years ago, I had this very same issue and I can't remember what the fix was. Rudder trim will realign the nose to heading momentarily then the nose will continue to track to left. I've fiddled with yaw damper on/off with no effect. On the external view, the rudder appears aligned with the vertical stab.
Not sure if related, but I can no longer use my strobe/beacon/landing lite switches on my Saitek multi-switch panel. The other switches work fine, and also the Saitek autopilot and radio panels work fine.
Any ideas/fixes?
Thanks
