Jonathon, did you read the whole thread above?
The axis is not tilted in any particular direction. 99.9% of the time the horizon is straight and level when I am going straight and level. However every now and then it flips to a large tilt when going straight and level. Then it will flip back to normal accuracy after some time (minutes). I do not have a video of this as it would require a lot of video to get the 0.1% when it fails.
