I too don't think this should be "normal", and find it interesting it seems common to digital servos on large control surfaces on our 3D planes, not just JR DS811s.
gpohly,
I think you will not find the answer in electronics. My situation made no difference if I was 3 feet or 35 feet away. The one thing I tried with moderate success was to get much longer servo arms from DuBro and get the clevis attachment point as far away from the surface as possible while still getting the maximum deflection. It did not cure my problems but helped a lot.
ifly,
We are suposed to want digitals for there precise movement and return to center as well as their power. Why build a high end digital without power? This precision and power are suposed to hold the surface at the dictated angle better.
