Mike, Why not just use the MkIII system. Weights and measures won't do you much good except to ball park what you need. The MkIII fittings and the bar may not be the most elegant, but it is adaptable to all different weights of ailerons.

I'm certain this would be greatly appreciated by more than just me.

The root cause of aileron flutter is the lack of wing stiffness. Due to the
fact that the wing can and does flex during flight in response to passing
through unstable air and or roll control movement, it causes the wing to
twist chord wise with the most of the movement taking place at the
unsupported outer wing tip. By doing so this tries to whip the aileron up
and down. The balancing of the aileron puts a mass ahead of the hinge equal
to aileron mass behind the hinge line and so the aileron will bounce up and
down but will not twist about the hinge due to wing twisting.
If you would like to read more about this, Google - 'NACA "aileron flutter"'

Rick,
I'd be happy to use the MkIII system, especially since I have a MkIII. But, in my MkIII builder's book (Mar '98 edition), it makes NO mention of aileron balancing, and practically nothing of even the ailerons.
Although I'm quite certain I could come up with something,.
I would still appreciate a photo or two, and if there is a reference to aileron balancing in a later edition, or even better in an XTRA manual, I would greatly appreciate it if someone could scan and send this updated information.

Mike, mine's from about the same era, and if the components didn't come
with your kit, I know they're available from Kolb. There's a "T" that
rivets into the outboard end of the leading edge of the aileron, and a
solid steel rod that slides into that and bolts into place. The only
picture I can find of it is with the wings folded ready to load in the
trailer. It shows the "T" fittings, but the balance weight rods are
removed and a steel bar is replacing them to help hold the wings solidly
while in the trailer. Lar.

Mike, Sorry about that, I lost track of the type Kolb we were talking about
