H3LLVIS

Hi, just bought T-33. Fantastic aircraft, but i've an issue with G3X. In detail i've the horizontal bars locked and inclined in the display. I've noticed one weird thing...it seems linked to the analogic instrument. If I try to uncage the instrument the bars seems to return working correctly. Anyway.... precession of the analogic instrument time to time affects the horizontal situation indicator in the G3X and Autopilot. Am I doing something wrong? Waiting for your kind reply. Greetz
