I had a similar problem with my XS wing. Owing to a manufacturing fault the
foam cut-out for the mass balance horn nearest the tip was not in the right
position. I considered briefly whether to reposition the mass balance horns on
the aileron accordingly, but Neville Eyre told me to leave them where they were.
He told me to cut away the inside layer of glass on the wing, and remove the
foam as required, to allow the correct placement of the mass balance boxes.
Having done this, scuff sand the adjacent area of the inner skin, and with a
small flox corner to transition from the skin to the foam, lay up 2 layers of
Bid, and peel ply over the top.
Hope this helps.
