3. Cut four 1" [25.4mm] pieces from a leftover 1/8" x 1/4"
[3.2 x 6.4mm] balsa stick.
Before proceeding, read steps 4 thru 9. This will give you a
better understanding of how to proceed.
❏
4. Check the fit of former F1 to the front of the fuselage.
The top deck should end 1/16" [1.6mm] aft of the front
edges of the fuselage sides. With F1 in place, the top deck
should be against the rear of F1. Note: It may be necessary
to trim the fuse sides to match the width of the firewall.
❏
5. Glue F1 to the upper part of the left fuselage side. The
line drawn across the top of F1 should be aligned with the
top of the fuselage side. Align F1 accurately with the slope
on the upper part of the fuselage side. The lower part of the
fuselage side angles forward slightly. Do not glue F1 to the
lower part of the fuselage side. Glue the top deck to the
fuselage side as well.
❏
6. Glue one of the 1" [25.4mm] strips that you cut earlier
to the fuselage side and the rear of F1.
❏
7. Glue F1 to the upper part of the right fuselage side.
The line drawn across the top of F1 should be aligned with
the top of the fuselage side. Make sure F1 is aligned
accurately with the slope on the upper part of the fuselage
side. Do not glue F1 to the lower part of the fuselage side.
Glue another 1" [25.4mm] strip to the right fuselage side
and the rear of F1.
❏
8. Prepare two of the 1" [25.4mm] balsa strips as shown
in the photo. Sand a curve along one side to match the
curve of the lower part of F1. Sand an angle along the side
of this curve. Study steps 9 and 10 to get a better idea of
how the strip should be shaped. This piece is fitted into
place in step 10, but it will help to have the part sanded to
shape first.
The lower front of the right fuselage side will now be glued
to the curved part of F1. The fuselage side must first be
wetted for it to bend around this curve. We have found the
best solution for this is 70% isopropyl alcohol (rubbing
alcohol), which will soak in rapidly and dry quickly. This
looks difficult, but if you proceed as instructed it works well.
