I know this is pilot error since no one else has reported this yet. I followed the tutorial to enable the Gyro pilot, however the heading drifts (mostly towards the co-pilot -- starboard) during a flight. My altitude remains rock-solid, so I figure I have part of it (Gyro pilot) enabled correctly. Few things to nte I set the "bypass valves" to their default setting of 3 I trim the aircraft to fly straight and level before enabling the gyro-pilot I enabled the two levers by my seat: Right one first to pressurize the system (wait for pressures to stabilize) Left one to enable GP The plane stays straight for a while, then begins to drift. Is there anything I am doing wrong? I have 1.62 installed in MSFS (latest build / updates) running on Win 10 professional Thanks for any help
