Steve,
If you mean the airplane is tail heavy in flight, you can adjust this by
shimming the front of the vertical stab. Adjust it so that the elevator is
neutral when you are straight and level. You will notice that the front
mount for the VS is designed so that this is quite easy. Don't go more that
.020 inch at a time.
If you mean the static balance of the elevator, paint could upset this a
bit. There is more elevator surface area on the trail side of the hinge.
Therefore more paint, more weight. Static balance is easily corredted by
adding or removing more weight.
The balance of the elevator, if I understand correctly is mostly to prevent
flutter. A slight imbalance should not have much of an effect at all in
flight. The effect of gravity on an elevator travelling at 100 KTS is
negligible compared to the aerodynamic forces.
If both elevators are static balanced individually, then the pair will be
static balanced when tied together. However on another pair, one could be
heavy on the leading side, the other equally heavy on the trailing side and
both would balance out as a pair. They would not balance individually.
Which is better? I don't know for sure, but I don't think it matters much
at all. I balanced mine individually, and it took no adjustments when they
were tied together as one. And it flys just fine.... REALLY fine.

Try Eric Jones' site at http://www.periheliondesigns.com
He has a trim wheel that can control a MAC or RAC servo so that the only
connection is two 22ga wires.
