FUSELAGE CONSTRUCTION
1.
The basic framework of the fuselage will be built upside down on the plan. Pin the FUSELAGE TOP FRAME PLAN to your
building board and cover with wax paper or plastic wrap for protection. Locate the plan on the building board so that former
F1 is just past the end of the board (the top of F1 has two "tabs" that must hang over the edge of the board when F1 is
installed later).
2.
Pin two 1/8" sq. x43" balsa sticks directly over the plan for the Top Longerons. Bend the longerons to follow the plan exactly
from former F2 all the way back to the tail end. Don’t worry about the area forward of F2 at this time - it will be pulled
together later when we install former F1.
Note: You will have to taper the inside edges of both longerons slightly at the tail end, as shown on the plan.
3.
Cut to length and pin in place all of the 1/8" sq. balsa crosspieces shown on the FUSELAGE TOP FRAME PLAN. Tack glue
them in place with a small drop of Thin CA at each end.
Note: Cut these cross-braces from the leftover 1/8" sq. from step 2 and from new 36" long stock. Do not cut them from the
last 1/8" sq. x43" stick, which will be needed for step 6.
Basic Rule of Model Building: Cut the longest pieces of 1/8" sq. balsa first, then
the shorter pieces, in order to make the most efficient use of the stock 36" long
sticks. This is good advice for this step and throughout the entire construction of
this airplane.
4.
Glue formers F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, and F13 in place.
Make sure all these formers are glued in perpendicular (90 deg.) to the building
board. Do not install former F1 at this time, or the 1/8" sq. balsa doublers that go
between F1 and F2. We’ll add them shortly. Leave the top frame assembly pinned
to the plan even after the glue is dry.
5.
Glue the balsa Keel into the notches in formers F2 and F3.
6.
Cut the last 1/8" sq. x43" balsa stick to 17" long to make the forward portion of the
Bottom Longeron. That should be real close to the length you need to go from the
notch in former F2 back to former F7.
Trial fit the piece in the notches of the formers. Final trim the length, if necessary,
so that the longeron ends halfway in the notch of F7. Glue in place.
7.
Cut the remainder of the 43" long stick from the previous step to 22" long. This is
the rear portion of the Bottom Longeron. Glue it in the notches of all the rear
formers F7 through F13. Let the excess length hang over past the tail end of the
fuselage.
8.
Use a 90 deg. triangle to mark and cut the tail end of the Bottom Longeron even with the ends of the Top Longerons.
9.
Cut a piece of 1/8" sq. balsa for the tail post. Note that the bottom end must be cut at an angle. Glue the tail post in place to
the fuselage framework.
