I started by placing the right wing tip and place to see exactly where the triming should occur, I drew thelines on both sides and cut away with the dremmel.
I then set the wing tip in place, duct tapped it, and started on the leading edge and alternated drilling and clecoing from the bottom of the wing to the top.
Once the wing tip was drilled and clecoed in place, I ensured the aileron was still in the nuetral position and marked out the 1/4 inch gap from the aileron to the wing tip.
I removed the wing tip and sanded the 1/4 line down with the dremmel and a little fine sanding drum.
