Trim the fiberglass patch that I added yesterday and add poly fiber filler to smooth out the irregularities. Also sanded and trimmed the top side of the fairing on the left side. I will finish sand the patch tomorrow. Trim and fit the F443 A coverplate under the horizontal stabilizer. Drilled the attach holes into the longeron. I managed to keep the coverplate in plasce while drilling with double sided tape. I used the dremmel tool's flexible shaft to drill the close holes. That worked out pretty good.
