I now have my head tracker assembled and honestly, it's been amazing and a complete game-changer for me.
Being able to naturally look around with a quick glance has made my flying so much more intuitive, and the tracking is super smooth with OpenTrack.
For anyone interested, I was looking for a decent TrackIR alternative without the insane price tag and decided to take a chance on the SWC D.I.Y Pro clip that i see on another forum. They also have ready-made versions and DIY kits. No affiliation, just a very happy customer who thinks more people should know about them. If you're in the market for a head tracker, you should definitely check them out. SWC TrackIT
