❏
21. Use a leftover 1/8" x 1/8" [3.2 x 3.2mm] balsa stick to
reinforce the trailing edge of the fuse sides and where the
horizontal stab will be mounted. This will provide additional
gluing area.
❏
22. Temporarily pin the horizontal stab to the fuselage,
making sure it is centered.
❏
23. Hold the fuselage on the wing and check that the stab
is level with the wing. Lightly sand the stab mount as needed
to make it level with the wing.
❏
24. Glue a filler stick cut from leftover 1/8" x 1/4" [3.2 x
6.4mm] balsa to the top of the fuselage, 3/16" [5mm] behind
the stab. Be careful not to glue the stab to the fuselage.
❏
25.Tack glue a leftover 1/8" x 1/8" [3.2 x 3.2mm] balsa stick
across the front of the stab saddle area of the fuse.
❏
26. Tack glue a 1/8" x 1/8" [3.2 x 3.2mm] balsa stick
centered on top of the sticks glued in the last two steps.
❏
27. Cut the 3/4" x 3/4" x 12" [19 x 19 x 305mm] balsa stick
in half, making two 6" [152.5mm] pieces. Tack glue these to
the sticks as shown.
❏
28. Using a razor plane and progressively finer grades of
sandpaper, shape the fillet blocks until they blend into and
follow the contour of the fuselage.
❏
29. Cut the fillet blocks and false stab/fin off the aircraft.
Remove the sticks used to represent the stab and fin.
