Mount the Wing
Mount the Wing
1. Locate the three plywood wing mounting plates.
Remove them from the die cut sheet and sand off any
rough edges left from the die cutting. Glue the three
mounting plates together in a stack with the shortest on the
top. Make sure the holes are lined up with one another and
wipe off any excess epoxy. Use clothespins to clamp the
wing hold down plate together while the epoxy cures.
Install the Wing Mounting Plate
3. Install the wing mounting plate into the cut-outs in the
sides of the fuselage. The tabs created by the two longest
plates fit into the notch in the lightening holes in both sides
of the fuselage. The back of the block fits into the
bulkhead. Use 6-minute epoxy to securely install the wing
mounting block into the fuselage. Apply 1/8" wing seating
tape to each side of the wing saddle to prevent exhaust
residue from entering the fuselage.
Mark the Wing
4. Insert the nylon wing bolts from the underneath side
Install the Blind Nuts
2. Install the blind nuts into the holes from the bottom
side of the mounting plate. Gently press the blind nuts into
place with pliers or a vise. The holes may need to be
enlarged slightly with a 5/16" drill bit. Glue the blind nuts
into place with a drop of CA on the flange of the nuts. Care
must be taken not to get CA into the threads of the blind nuts.
of the wing mounting plate. The bolts should be even with
the wing seating tape. They should touch the wing lightly
when the wing is fully seated in the wing saddle. Paint the
tip of the bolts with a slow drying paint. Before the paint
dries, place the wing into the wing saddle. The wet paint
will mark the locations that will be drilled for the wing bolts.
Drill the Wing
5. Drill a 1/4" hole at each paint mark. The drill should
be held perpendicular to the bottom surface of the wing.
The bolts must thread into the blind nuts squarely.
