Tested:
Nose wheel stays straight, plane turns, but not aggressivly.
The strange thing is though, that it works during take off roll and landing roll, but once a braking force was applied, the nose wheel refuses to turn, and the plane gets uncontrollable on ground. After applying take of thrist (thrust = 100%) it starts working again after a few seconds and stops immediately again after some braking force on either wheel was applied.
My rudder bindings are the same as pre SU6, sensitivity settings also the same.
This is definitly a bug introduced with SU6.
