Hi.
I am having trouble with many of my planes, they roll to one side (trimmed properly, no wind, even fuel levels, but the hydraulic levels are not even?) on auto pilot the planes will fly with 1-4 degrees bank and stay that way. Any ideas? Not all planes have hydraulic levels but the default Dash 8 does and it is definately cruising at 3 degrees bank, the difference in levels is 2% any ideas on the cause of all this? how do Hydraulic levels change on either side more than the other????
