In the picture above the servo arm is relatively flat but not touching the skin. I have about 80 degrees of travel on that panel (and all my x 2 panels)

You could also present better mechanical advantage by not burying the brass horn quite so deep into the surface and reduce the torque requirement especially at full travel. Maybe some of the more "mechancially inclined" would care to comment but I remember experimenting with different depths and found that just 1-1.5 mm of brass horm height really translated to lower servo buzz.
