The wireless tracker finally arrived and I mounted it on top of a baseball cap with the velcro pieces that it came with. Installed everything (+ Opentrack 2.3.9) , calibrated it, and it works in P3D V4. However, I have a constant counterclockwise movement on the yaw and pitch axis. After an hour of fiddling, rolling my head and craning my neck around I'm ready to puke on my keyboard.
I also found it somehow does not really work well with my edition of Chaseplane, the camera software, but that might be a result of the moving axis problem. Chaseplane tries to reset the camera if it moves beyond the settings assigned in the program.
Anyone here had a similar problem?
[Edit: Never mind, it was a calibration issue. ]
Cheers,
Mark
