I was in contact with Dorian from EDTracker since 2 weeks and he sent me a couple of email with possible solution to my drift problem.
So, I took friday afternoon to try all he sent me and here’s the results:
August 12th: He sent me a link to try to solve the problem. http://support.edtracker.co.uk/kb/faq.php?id=3 Also the “Auto bias” button is mentioned but this is now called “Set Level”.
August 16th: He talked to me about my cockpit and seat. As I said to him previously, my entire pit is in wood and fiberglass. No metal/aluminium. Every calibration are done in the pit/seat since the beginning. He also suggested me to do a degauss.
Also one of my colleagues explained there is a possibility that for whatever reason, sometimes, the magnetometer itself inside the EDTracker can become magnetised. In this case there is a degauss function built into the user interface.
So I make the degauss and I recalibrated the entire tracker. The degauss fonction is in the dev mode. Developer mode is now found under Config -> Mode -> Dev.
August 20th: He send me an other email and talking about the "Windows built in “USB Game Controllers”. I don’t know what it is and how it works so this could not be my problem as I have not try anything like that.
Just to confirm, I’m using EDTracker Pro UI V.3.0.0.9 and the opentracker V.2.3.7
As I don’t have any headset now, the tracker is fixed directly on the top of my cap with a drip of hot glue. The cap don’t have any metal. Only fabric.
So now, august 27th, after trying all those solution friday the final result is: The drift problem seems to be solved. I made a 30 min flight in my pit friday and a couple of hours flight saturday and sunday. I will work on my curves too to try to adjust the angle of view but, up to date, that’s the best results I ever get.
Thanks to Dorian for his help.
So now guys you havr the solution for the drifting problem. Good luck!
