The wing is attached to the fuselage by screws which fit
in threaded sleeves glued to a plywood support plate.
The machined plate can now be glued in place:
The first step is to mark the hole positions on the fuse-
lage, working through the wings.
Place the wings on the fuselage and set them exactly
central and "square". Check that the leading edge is
fully forward.
Fix the wing to the fuselage with a strip of adhesive
tape.
Now drill two holes directly into the fuselage through the
wing holes, using a 4.5 mm Ø bit.
If you now remove the wing again, it will be clear where
the plywood plate with the threaded sleeves has to be
installed.
Roughen the joint surfaces on the inside of the fuselage.
Glue the plywood plate in the fuselage using five-minute
epoxy, taking care to align the threaded sleeves with the
previously drilled holes. Take care that no epoxy gets
inside the threaded sleeves.
A locating peg has to be glued in the leading edge of
each wing panel at the root; their purpose is to locate
the wing at the front.
The first step is to glue two 3 mm Ø holes in the front lip
of the wing saddle on the GRP fuselage. The two holes
should be 16 millimetres apart, i.e. 8 millimetres from
the central moulding seam on each side.
Work cautiously and accurately when drilling these
holes, as they are important for the correct alignment of
the wing on the fuselage.
Now place the wing on the fuselage, fit the two plastic
retaining screws, and set the wing exactly "square" once
more. You can now mark the position of the holes on
the wing leading edge using a felt-tip pen, working
through the holes in the GRP fuselage. It is a good idea
to stick a piece of paper masking tape to the leading
edge, as this makes it easier to see the marked points.
Drill 3 mm Ø holes in the wing leading edge at the
marked points, and glue the locating pegs in place using
cellulose adhesive. Round off the front end of the pegs
to make them easier to insert.
Offer up the wing again; you may need to file out the
holes slightly to obtain an accurate fit.
