1. Popped the new fairing off the fuselage. It looks 100% better than the first one! Rough-trimmed it with a pair of snips. 2. Laid up 3/4" wide yellow tape along the previously-marked fairing edge line on the airplane. 3. Iteratively trimmed the fairing until about half of the yellow tape showed underneath. 4. With the fairing in place, I laid a new tape line directly over the first line, marking the trim edge on the fairing. Marked it with a silver Sharpie marker. 5. Trimmed to this final line with snips. 6. Removed all the clay, aluminum tape, packing tape, and filler blocks from the fuselage and tail. Cleaned everything up. 7. Fit the new fairing and pronounced it very nice. (There are some minor ripples that I'll be able to smooth out before the next layers of carbon fiber are applied.) Overall, re-doing the fairing was a good idea.
