I have a TIR 3 with the vector add-on and was holding out for the TIR 5 or 6 or whatever is coming out after the TIR 4. NP sure are taking their sweet time on that! When I saw Hat Track I decided to get it instead of waiting for the next TIR, especially since the price was pretty decent.
But it doesn't work better, its worse! Im back to using my TIR 3 w/ vector for now. TIR is way smoother and more responsive than the Hat-Track. Kinda funny for something as long in the tooth as a TIR 3 to come out on top. The TIR has more game support, too. The Hat-Track only works in MS Flight sims, you can't use it in IL2, LOMAC, CFS, etc. Wish I'd paid better attention to that before I snapped it up.
I like the Hat-Track headset clip more than the NP one, they're about the same size but the Hat-Track one clips on better. Too bad I cant use it with the TIR, the software can't see it for some reason.
Had a couple problems getting the Hat-Track to stay aimed at me, it kept wanting to tilt upward. But mounting it on a flat panel was easier than the TIR 3 - I think you know what I'm talking about!
