4. The forward fuselage side (FFS) with the deeper notch
is the right side of the fuselage. This is important!
Somewhere on the part mark "right" to make sure that there
is no confusion as you proceed to the next few steps. The
deeper notch on the right side of the fuselage is what builds
in the right thrust so it is important to install the left and right
side correctly.
5. Unroll the plan sheets. Roll them inside out so they will
lie flat.
6. Locate the fuselage on the plan. You may find it helpful
to cut the plans and separate the fuselage side view from
the fuselage top view, making them a more manageable
size to pin to your building board.
7. Position the fuselage side view on the building board.
Cover the plan with Great Planes Plan Protector or wax
paper so glue will not adhere to it.
8. Pin the left forward fuselage side (FFS) over the plan.
(Remember, the left side is the one that has the shallow
notch cut into the front.)
9. Locate two 1/8" x 3/8" x 24" [3 x9.5 x 610mm] balsa
sticks. These make up the fuselage side. Glue them in
place at the rear of the forward fuselage side (FFS).
10. Glue the die-cut 1/8" [3mm] balsa aft fuselage side
(AFS) to the balsa sticks at the rear of the fuselage as
shown on the plan. Cut the balsa sticks flush with AFS.
11.Locate the 3/32" [2.4mm] die-cut balsa stab doubler
(SD). Glue it in place onto the balsa aft fuselage side (AFS),
aligning it with the bottom and rear of the fuselage side.
12. Repeat steps 8 - 10 for the right fuselage side.
Remember, the right side mirrors the left side of the fuselage.
Be sure not to build two left fuselage sides!
