Finished aligning the R wingtip to the wing and aileron, then drilled the mounting holes out for the #6 attach screws.
I also spent time fitting the wing root fairing so it evenly matches the contour of the fuselage side. I tried to test-fit the rubber grommet to see how much gap would be required -- it looks like at least 1/4" will be needed.
Wing root fairing is clecoed in place, and the trimming has begun.
