Angier,
The counter weight still needs to 'hang low' for an overbalanced condition.=
  It doesn't matter if the elevator is right side up or up side down.  =
BTW, the 3/4" low equilibrium point is also a function of the vertical =
offset of the CG to the hinge line.  If your hinge line were exactly =
through the center and the part symmetric top to bottom, any overbalance =
will cause the elevator to rotate into a vertical position.  The CG of the =
aileron hangs well below the hinge and can therefore be easily trimmed to =
have a specific deflection off horizontal.  You should balance to level =
and then add some measured guess for the paint.  Be generous.  The paint, =
although light in terms of oz/ft^2 , has a big moment arm advantage.
