I don't know if anyone else is having this issue, but my heading indicator constantly drifts to the point I can pause the plane and watch it move. This has to be be more than simple gyro drift. In fact, I tried turning on the gyro drift auto calibration to see if that changed anything, but it made no difference.
At first I thought it might have to do with the controls. I am running with a Honeycomb Alpha yoke, a Thrustmaster throttle and rudder peddles. I also have a Thrustmaster G1000 stick as well as TrackIR.
Today I unplugged ALL of the controls and ran with only a keyboard and mouse (I even had TrackIR shut down). After verifying in the control settings that it only detected the keyboard and mouse, I loaded up a saved flight 3,000 feet up in a Cessna 152. Lo and behold, the course heading was still visibly moving all on its own, even while I had the simulation in pause mode. I hit the D key to reset the heading and it jumped back to correct and then started visibly wandering off all on its own again.
I have been thoroughly enjoying the sim, but it is to the point where I can't trust my heading indicator at all. I have had it lead me astray doing something as simple as a single circuit.
Has anyone else come across this issue? Are there any known corrections or workarounds? I am finding it quite frustrating.
