   The easier solution is what Lancair did on the Columbia, which was to put
counterweights on arms that fair into the wing in level flight.  I don't
know if that's possible to do in an ES, as we didn't know any better at the
time and did mine the regular way, but it may be worth looking into.
   The left aileron in particular, with the trim tab and servo in it, was a
real bitch to balance and now weighs a ton.  We had to pound, shape and
grind the weights to hang well forward of the flange and go quite a way down
the length of it to get sufficient balance and adequate travel.  Since there
was very little lever arm to work with, the weight required was pretty
sunstantial for such a small control surface.  After gluing the weights in
place with 5 minute epoxy, we wrapped everything in a layer of fiberglass so
it stays put.
