Build The Fuselage; Mount The Wing - GREAT PLANES Shoestring ARF Instruction Manual

3. Prepare 1/2 oz. of 30-minute epoxy. Add 1/2 oz. of
microballoons. Working quickly, thoroughly coat the inside of
both wing halves where the joiner fits and one half of the
joiner with the epoxy and microballoons mixture. Making
certain the joiner is upright, insert the coated end into one of
the wing halves. Coat the other end of the joiner with the
remainder of the epoxy and microballoons mixture. Proceed
immediately to the next step.
4. Prepare an additional 1/4 oz. of 30-minute epoxy only
(no microballoons). Coat the ribs on both ends of the wing
with the epoxy. Join the wing halves tightly, holding them
together. Use a paper towel to wipe away excess epoxy that
comes out of the wing. Tightly hold the wing together with
masking tape, making certain both halves are in full contact
and that the leading edges and trailing edges align. Wipe
away excess epoxy and do not disturb the wing until the epoxy
has fully hardened.
5. Connect the servo wires to a Y-harness (HCAM2500
for Futaba). Secure the connection between the servo wire
and the Y-harness with heat shrink tubing, tape or clips
suitable for that purpose.

BUILD THE FUSELAGE

Mount the Wing

1. Inspect the blind nuts that are pressed into the bottom
of the wing nut plate inside the fuselage. If the nuts are not
securely pressed into the plate, remove them. Apply a dab
of 30-minute epoxy to the flange around the blind nuts, then
reinsert them into the plate. Use a metal 1/4-20 bolt and a
large washer to draw the blind nuts all the way up into the
wood by tightening the bolt to the top of the plate.
2. Cut the covering from the holes in the leading edge of
the wing for the dowels and near the trailing edge for the
wing bolts. Temporarily fit the 1/4" wing dowels into the
leading edge of the wing.
3. Test fit the wing to the fuse and bolt it into position with
the 1/4-20 nylon wing bolts. If necessary, enlarge or adjust
the wing bolt holes in the wing so the wing bolts will align
with the blind nuts.
4. Unscrew the wing bolts about 1/2". Place the 1/8"
plywood wing bolt plate on the wing centered on the wing
bolts. Mark the location of the wing bolts on the plate.
5. Drill 17/64" (or 1/4") holes through the center of the
wing bolt plate at the marks (see the photo at step 7).
