Below you can download the Track IR Profile I use for IL-2. Back in 2015 I used this video to create my initial Track IR profile.
I have a pretty distinct dead zone in the middle of my axis, to stabilize my camera around the gun sight.
Note that I use both full stabilization in IL-2 and in the Track IR Software. This is mainly to make it a bit more pleasant to the viewer of my videos. Up to you if you want to use it or not.
On a Windows 10/11 System the file below has to be place in C:\Users\[yourAccountName]\AppData\Roaming\NaturalPoint\TrackIR 5\Profiles
