I use version 1 with no problem. I even use the IL2 profile.
(assuming you mean MSFS 2004)
Use it JUST like IL2. When in cockpit press "S" once to cycle the view. The second option is the virtual cockpit. Ahhhhhhhh. SWEET!
When you use Track IR look to your left and DOWN. Then press Ctrl E. The first time I did that the door of the Cessna opened and a bit of vertigo was induced. I got a kick out of it, seeing the wheel strut and Washington State float by.
I don't think 6DOF is supported in Track IR 1.
