Aircraft control trouble

[RAF_Marmaduke]

I can trim out the right hand turning in the hurri and the spit to a point where you only have the torque to deal with.

The 109 seems to be a problem because there is no rudder trim, as we know, and the torque is too prominent. I suspect the rudder isn't centred, can someone confirm this?

I hope it's not related to a particular make or type of joystick (logitech freedom + X52 throttle setup here)
