Just bought it yesterday afternoon and tried it out in FSX last night, mostly flying VFR in both fixed wings and copters around CYNJ, CZBB, and KFHR--all close by to where I live.Set-up was quick: open the package; take out the clip, clamp, and IR thingy; attach the thingy to the clamp; attach the clamp to the monitor; attach the clip to a baseball cap; download the software, and plug the USB cable into the computer--and that's it. It probably took me longer to type out these three sentences than it did to set up the TrackIR.So ... once I got everything running, I put on the ball cap, fired up the software, and played around a bit with the configuration program. Pretty cool, but I actually didn't make any adjustments. I started FSX, and ...... in a word: Wow!TrackIR just worked perfectly, right out of the box. Oh, and what an immersive experience! Probably for the first time ever in a flight sim, I felt really as if I were in the cockpit. The control of my FSX point of view came naturally, with almost no adjustment period for me apart from learning how far I needed move my head to look around virtually. In addition to accessing switches and looking closely at gauges and so on quickly and easily, I found that I could do what I naturally do when I drive: I could look in the direction of where I wanted to go and "steer" the aircraft there without having to do so by manually moving around my POV with my FF2's hat (something we don't do when we drive, of course). Doing so made landings much easier (tracking the runway was the key here). It also made landing and hovering helicopters much easier. I can see that I'm going to get much, much more enjoyment out of FSX ... and I already enjoy flight simming a lot! :-)I just have one question about TrackIR, though:Why hadn't I gotten one before? :(

Welcome to what some of us have enjoyed for quite a while. I simply can NOT fly without it.Enjoy!Vic

I've got version 4 but am thinking of getting version 5 along with the new CH Eclipse yoke to replace my existing CH yoke.Upgrades, upgrades........Graham

I purchased the IR5 a few days ago and really enjoy using it.

I purchased the IR5 a few days ago and really enjoy using it.

Two months ago here. It just works. The more familiar I become with the product, the more I appreciate the features. That is, by the fifth version they know what they're doing with the hardware and software, which might not be readily apparent to a brand new user. I had to crank the smoothing function up to 50% (my old brain can't handle maximum precision) and I also changed the response curves, but this configurability is another strength.I've also been using TrackIR in Arma II, really cool.

Has anybody experience in comparison with TrackIR 4?

I'm going to add a dissenting opinion here... ...in the interest of representing another side - but not for technical reasons, but more for personal ones. From the top, I have never been a big fan of the 3D virtual cockpits. I prefer the easier to manipulate 2D cockpit, and my virtual airline experiences several years ago really solidified my opinion on the "superiority" (*for my flying style) of the 2D. I purchased TrackIR4 several months ago on the recommendations of many users out here who have raved so glowingly about it, but my experience was a little different. From an installation and setup standpoint, it could not have been easier. It went painlessly, and as others have mentioned, it integrated seamlessly into my FSX experience. I was initially VERY impressed with how it functioned. Rotate my head left, the sim looked left! Rotate right, I look right! Move in and out, up and down, and I thought I was in an airplane! This buzz quickly wore off for me though. Being a 2D cockpit person, I needed to adjust a bit to the 3D cockpit. After a few days... a week... and two weeks, I just couldn't bring myself to accept the 3D cockpit as a functional interface when the 2D was just so much more efficient. I initiated a return with NaturalPoint just prior to the return time limit was to expire, and they were perfectly professional and willing to help. I can't speak highly enough of their organization. The moral of the story: If you are a VC/3D cockpit user, and have adapted and enjoy that method of flight, you will VERY MUCH enjoy the use of the TrackIR product. If you are a 2D/Traditional cockpit user, you shouldn't expect it to convert you to a 3D user. Those of us who prefer the 2D side of things do so for many common reasons - ease of use, clear and uncluttered access, the ability to "keep our eyes on the road" while manipulating systems, etc.... Many of these reasons (and others as well) become tested when you enter the VC realm. (You can use the TrackIR in 2D cockpit mode, however you lose the key frame of reference that is the cockpit itself when looking around) While it is a technical tour de force, and a very capable tool for a VC pilot, I learned through experience that despite all the praises that TrackIR has rightfully earned, it isn't quite for all pilots. -Greg
