Both ailerons are attached but as yet unbalanced. The left one is a good fit all
around but I have a problem with the right aileron fit. Here is the situation.
The top aileron surface along its leading edge is both flat and atraight from end
to end. Each aileron end is flush with the top wing skin trailing edge but at the
center, the aileron top surface is .082 below the wing trailing edge. In other
words, the right wing trailing edge has a slight bow (.082) upward and this bow
is greatest at mid-point between the hinges. The rest of the wing trailing edge
is pretty flat, straight and true.

So, for obvious turbulent reasons, I don't want any part of the aileron leading
edge to be below the wing trailing edge. I was thinking that I would build up the
aileron surface for its full width and to a point about an inch back from its
leading edge with enough bid to bring the aileron surface flush with the wing
trailing edge. Then, I would fair in behind with micro.

Does this seem like a reasonable solution?

[Angier, if all the rest of the trailing edge is nice and straight it
sounds to me like you have a bump in the airfoil where the wing TE is
bowed upward from the aileron LE.  The bow is slightly less than 3/32" and
I'll bet you could get it out with a heat gun and some well placed
'massaging' of the offending area.  Once you work the area down, clamp it
between some angle iron while it cools off.  I took all the 'wavies' out
of my h.stab TE in a similar fashion, and applied an extra BID both
inside and outside to lock in the correct (unwavy) shape.  Whaddya think?
Anytime you can fix a misalignment without having to add more weight
in the form of micro you're ahead of the game.  IMHO anyway...
