The wing
The wing is assembled from parts (17) to (29), and is the most important component of the
model. The two wing panels are assembled separately on the building board before they
are glued together. Start with the right-hand wing panel: cut out the wing plan and tape it
down to the building board. Lay clear plastic film or greaseproof paper over the plan to
protect it.
Pin down the wing leading edge (17), the trailing edge (18) (caution: the front face must
be at right-angles to the bottom face) and the main spar (19) over the plan, spaced to
suit the length of the wing ribs. Tip: fit two or three ribs in the notches, position them directly
over the plan, then pin down the spar, leading edge and trailing edge: this ensures that the
stripwood is correctly positioned. The rest of the ribs can now be fitted into the structure,
and all the joints glued securely.
When the glued joints have set hard, use the angle template (W) to mark the chamfer angle
of the leading edge, trailing edge and main spar at the centre of the wing, and then cut off
the excess strip material. Cut off the same three strips (17) to (19) flush with the tip rib.
Glue the triangular-section wingtip block (28) to the end of the wing panel. Allow the glue to
harden, then plane the block to follow the shape of the rib before sanding it to final shape
as shown.
The outline of the wingtip develops naturally when you sand the top surface flush with the
wing profile.
Pin down the wing panel on the building board, and glue the dihedral braces (21, 22 and
23) to the appropriate strips; note that the centreline of the braces should line up exactly
with the prepared end of the strips. Build the second wing panel in the same manner.
Joining the wing panels
You will need a dihedral support for this stage: the support is made by cutting the drawing
from the plan, sticking it to a piece of card (e.g. the bottom of the kit box), then cutting it out.
Score and fold the support as shown, and glue the ends as shown. The height of the
support should be 114 mm. Pin down the left-hand wing panel on the building board, then
offer up the other panel to it. Check that the wings fit together snugly, then apply glue to the
dihedral braces (21, 22 and 23) and the joint faces of the leading edge, trailing edge and
spar. While the glue is drying, press the dihedral braces against the strips using spring-
clamps and pins. Place the card dihedral support under the fourth rib from the tip of the
right wing panel to obtain the correct dihedral.
Cut the sheet panel (25) to fit, and glue it to the wing centre section as shown. Glue the
wing locating piece (29) in place, then fix the gussets (24) between the wing locating piece,
the trailing edge and the wing ribs (27).
When the glued joints have set hard, rub down the wing structure overall, taking care to
remove any projecting parts of the wing ribs where they meet the leading and trailing
edges. The basic airframe of your PILOT is completed by checking the whole structure.
