I tried the
SM3D12 in Massachusetts and it couldn't move to Galaxy 10R. The rotation angle was too small. So, I understand what you're going through. I don't believe that there is anything that you can do because the SM3D12 has hardware limits at about +/- 47.5 degrees. My suggestion is to invest in a
Stab HH90 motor. They are pole mount motors and have a rotation angle at about +/- 65 degrees.
