I have HSFX 4.1.1 and Track IR 4 as weel but I don't get all the degrees of freedom. I can't zoom in and back in the cockpit and that's a shame. Do you have this problem too?

You have gotten just about all the good advice there is ... but just one more, okay ?

In game, push your star key * on the num pad to bring up the menu in the following picture and make sure your settings are the same.

That's one of the things I learned when I couldn't "lean in forward" to look at my gauges nor get any other of the 4 degrees.

Hope this helps.
