TrackIR and FPS

I bought a TrackIR (version 5) a few years ago but hardly ever used it. I wanted to try to use it for flight sims but never got around to using it. Well, I dusted it off and used it to play some Arma 2 this past weekend. All I can say is....WOW! I should've been using this a long time ago. While I realize that not all games allow for head-tracking, Arma does (I've many of the Arma variants, including Arma 3). I also used it a bit to play some War Thunder. It was awesome there as well, allowing for a very immersive bit of gameplay (although I just used the test drive feature to test the hardware). To use TrackIR with War Thunder will also, for full immersion, require the use of HOTAS, which I do have (I've the Saitek X52 Pro throttle and stick combo), as well as rudder pedals, which I do not yet have (I'm in the process of deciding which to buy...I'm not looking for Gucci equipment...just some decent pedals to facilitate gameplay). I'll be testing other FPS games to see if they allow for head-tracking. I may also delve into other flight sims such as DCS and the IL2 series. Stay tuned.
