RV-7 with AP74, D100, EMS D10. Latest 5.4 software works really well on altitude hold. This plane has always wandered around the Hdg, Trk and Nav.
After sorting out issues with the 5.4 upgrade, some test flights revealed a serious wandering or up to 20 degrees either side of the Hdg or Trk. No difference was noted with either Trk or Hdg modes. In itial setup atefr installation took some time tio get these functions working better, so settings of 100% on the torque and 6 on sensitivity seemed to work best but not cure the problem.
After reading the forums etc. as well as carrying out the Dynon service on the servo with the play in the shear bolt, things were slightly more improved, but not cured.
Today while trying it out with sensitivity set as high as 25 no cure could be found at all. I suspect that the original problem of the play in the servo drive shaft and arm are the real culprit here again.
Is there any permanent cure for this without buying a new servo?
