How to cut covering from balsa.
Use a soldering iron to cut the covering from the stab. The
tip of the soldering iron doesn't have to be sharp, but a fine
tip does work best. Allow the iron to heat fully. Use a
straightedge to guide the soldering iron at a rate that will just
melt the covering and not burn into the wood. The hotter the
soldering iron, the faster it must travel to melt a fine cut. Peel
off the covering (see the photo at step 11).

4. Remove a 1/4" strip of covering from the center of the
underside of the stab. Glue the small ventral fin in place with
medium CA.
❏
5. Aligning the end of the skid with the trailing edge of the
ventral fin, push the tail skid into the ventral fin. Cut the
covering along either side of the tail skid and remove it. Glue
the tail skid in place with medium CA.

6. Cut the covering out of the slot on the top of the fuse.
Test fit the fin in the slot in the fuselage. When you are
satisfied with the fit, mark a line on both sides of the fin
where the top of the fuselage contacts the fin. Trim the
covering about 1/16" [2 mm] inside of the lines.
