Back to the tail...

a. We added 1/8 x 1/4 balsa strips to the elevator fillers and trimmed/sanded to make the gap with the elevator even and parallel. Then re-cover with white Ultracote.

b. Before installing, we test fit the vertical stab. It required a bit of trimming and sanding to get the back edge flush and inline with the end of the fuse.

c. Then, put it all together and mark all around with a water-based ink pen.

d. Cut just inside all the lines about 1/16" and remove the coating for the glue joints on the veritcal stab, fuse, fillers and horizontal stab.

c. Install the vertical stab, and straight-edge the rear to the fuse again. Check square to the horizontal stab (lucky this time, it was right).

d. Wick in liberal amounts of thin CA while pinching the tail slot together against the v-stab.

e. Install the fillers and wick in thin CA all around.

f. We used the white RTV silicone to finish all the joints. This provides fuel sealing and improved appearance.

Now we're making some progress.
