This is just a suggestion - My $0.00 worth.

 

Properly rigged ailerons have a slight float or dead band partially available from lash in the linkage.  If so, the airplane may experience slight lateral imbalance that a sensitive AP may pick up and try to correct.  Holding the stick reduces the dead band movement.  So ....

 

One might try an experiment - Rig the ailerons ever so slightly up (say a half or full turn in on the final aileron linkage rod end on each side).  This may result in a very slight air load on each aileron in level flight thus elimination of oscillation in the dead band?  This also results in the up aileron going up more before the down aileron is, uh, going down. 

 

Like I said, for what it's worth,

Does anyone who has a sorcerer find it tracks smooth? On my AFPilot the standard servo has a problem rolling at high speed. You can hear the servo ratchet as the stepper motor jumps. Once it does this it starts a sort of oscillation.  Back and forth at a fairly high rate. Doesn't turn to much. If I hold the stick steady it calms down. From what I see quite a few have had to upgrade to the higher torque servo. Since I just bought my setup this year would be nice had they just quoted it with the high torque knowing the standard might be too weak.
There was an S-TEC 55x in it before. But since the HSI was upgraded to glass nothing wanted to talk to it anymore. Barely a fancy wing leveler at that point.

Bill which tru track do you have? What is it hooked to that is driving it.
