6. Trim the covering from the stab just inside the lines you
drew. Wipe away the lines with denatured alcohol.
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 fi ne tip
does work best. Allow the iron to hear 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
fi ne cut. Peel off the covering.

7. Insert the elevator joiner wire into the aft end of the stab
slot. Slide the stab into the fuselage and center its position.
Stand back several feet and view the model from behind.
Ensure that the stab is level in the fuselage by confi rming it
is parallel with the bottom wing. If not, use tape or a weight to
level the stab. When satisfi ed, glue the stab into the fuselage.

8. As you did with the ailerons, join the elevator halves to the
stabilizer using the elevator joiner rod and CA hinges. Before
gluing the hinges, be sure that the elevator halves move freely
up and down. Glue joiner wire in place using thin CA.

9. Trim the covering from the vertical fi n slot in the fuselage.
Fit the vertical fi n into the fuselage and trace the fuse shape
onto the fi n. Remove the fi n, cut the covering below the lines
you drew, and glue the fi n into position. Do not remove the
covering from the trailing edge of the fi n.
