I was messing around in the Zero (Note: and this is true for all three A6M models) The Track-IR Default postion is located down in the cockpit, practically in the seat cussion. The Track-IR now effectivly has 3 Degrease of freedome - Pitch, Yaw & Roll - but not the Six it should. Therefore, there is no way, short of turning off Track-IR, to lift the pilot head up to see out the pipper, out the back of the plane, or even over the the side-glass.
I set my Track-IR back to the default profile, but this had no effect.
As ImADot said, this is making the airframes affected unplayable.
Hope the fix update comes out soon!
