9. Adjust the length of the aileron pushrods if necessary
(by twisting the clevises) to bring both ailerons into their
neutral positions at the same time.

1. Pin or tape the fuse plan to a flat surface and cover
it with waxed paper. Trial fit a die-cut 1/8" balsa Upper Front
Fuse Side (CUB4F01), Aft Fuse Side (CUB4F02) and
Lower Fuse Side (CUB4F03) together as shown in the
photo. Sand them as necessary to achieve a good fit and
glue them together with thin CA. HINT: You can also check
the alignment of these parts using a straight edge along the
lower aft edge of the assembly. Wipe off any excess glue
with a paper towel (before it cures).

2. Glue a die-cut 1/8" ply Cabin Side (CUB4F04) to
the fuse side.

3. Remove the fuse side from the plans and inspect
the glue joints for gaps, adding thick CA glue to any open
joints. Sand the glue joints smooth on both sides using a
T-bar and 150-grit sandpaper.

4. Repeat steps 1 - 3 to build the other fuse side. Place
the two assembled fuse sides together and sand the edges
as necessary to make the two sides identical.
❏ ❏
5. Glue a die-cut 3/32" balsa Lower Fuse Doubler
(CUB4F06) to the fuse side. The front and lower edges of
the doubler should be flush with the edges of the fuse side.
❏ ❏
6. Glue a die-cut 3/32" balsa Upper Fuse Doubler
(CUB4F07) in place. The front and top edges of the doubler
should be flush with the edges of the fuse side.
❏ ❏
7. Glue a die-cut 3/32" balsa Aft Fuse Doubler
(CUB4F08) in place. It should line up with the fuse sides as
shown in the photo.

other fuse side. Be sure to make a Right and a Left side!
