Ok I made a little test flight with this tool.
I think I will be using it a lot !!

There are a few important points, though:
- the beta update is necessary for using in FSX. It brings the simconnect ability.
- once the tool is launched, the only thing you have to do is to select "simconnect" in the protocol field. Then press "start" button, and launch FSX. Your head will move, nothing to configure in FS ! 8-)
- the tool has to be configured properly for pleasant use, mainly for the filtering settings and the response curves, because the default settings might not be suitable for everyone.
- the movements of your head in the sim are a little bit late compared to your own head, but after a short while it's easy to get used to it

- the movement of the head is not completely precise, that is that if you move your head into a certain angle and then freeze, the head in the sim will move as well, but will it will not always completely freeze, due to lack of precision. During flight, this gives a really great effect, it's like the aircraft comes to life ! But when you have to click a button, it can become a little bit difficult to aim sometimes

My final impression is that I am extremely pleased. I made a flight around a small airport in the Tiger Moth, and it was really a blast to put the head on the side to taxi, and to look around while flying. It's hard to describe, and the owners of TrackIR certainly know the feeling. Sure the tool is less efficient than a real TrackIR, if I refer to the various TrackIR videos to compare. However, for a freeware, the level of quality of this little tool is definitely pleasing !
