Go to Vansaircraft.com. Support heading, Construction FAQs, Heavy Wing Analysis. Start at the beginning, work to the end.
You might also want to read through the service bulletins as a few will apply to your RV.
Just a heads-up; adjusting an aileron up or down will have no effect on a heavy wing. It will just move the neutral position of the stick, and change the effective washout (or twist, which shouldn't be there on an RV) of *both* wings.
Don't feel bad about that mistake; I have personal knowledge that you're not the 1st.....

BTW, you can get a pretty good idea if there is any twist in the ailerons or flaps by measuring the angle with a digital level at each end rib while the control surface is held stationary.
Or just sighting the trailing edge from behind. Line up the bottom of the aileron with your "Mark 1" eyeball. You will see any twist comparing the ends.
If there is any twist, you will see more of the bottom at one end or the other.
If I am rembering correctly, there is another way to check for correct aileron rigging in the "neutral" position.
1. Remove both wing tips.
2. Insert a long dowel rod in each of the tooling holes in the outboard wing ribs (nose rib, main wing rib, and aileron rib) total of 6 rods for each wing.
3. Lay a long straight bar (or whatever) across all dowel rods. They should form a straight line.
This check does not test for aileron twist.
If you happen to know of a local builder, either a -4 or a -6, he may still have the original shipping crate plywood top cover that contains the wing planform stencil that the builter was to cut out and use to align the aileron with the wing. This method was an alternate to the "dowel rod" method mentioned above. I still have my plywood templates (made two of 'em) and someone in my area ends up using them, on average, once each year to check for rigging problems.
