wing halves together, removing any excess epoxy with a
paper towel dampened with isopropyl alcohol. Use masking
tape to hold the wing halves together while the epoxy cures.
❏
6. Use 6-minute epoxy to glue the two 1-5/8" [41.3mm]
wing dowels in the wing dowel holes. The rounded end
should protrude from the wing approximately 1/2" [12.7mm].
❏
1. The plastic wing bolt mounts are temporarily glued to
the inside of the fuselage. Use a T-pin to locate the four
wing bolt mounts’ screw holes in the side of the fuselage.
Use a sharp hobby knife to cut the covering from the screw
holes. Use four 4-40 x 3/4" machine screws, four #4 flat
washers and four 4-40 lock nuts to attach the wing bolt
mounts to the fuselage sides. Do not crush the balsa
fuselage sides by overtightening the screws.
❏
2. Test fit the wing on the fuselage, checking that the
wing bolts will thread into the wing bolt mounts. Remove
the wing bolts from the wing.
❏
3. With the wing centered on the fuselage, center the
plywood wing bolt plate on the aft edge of the wing. Trace
the outline of the wing bolt plate onto the wing.
❏
4. Use a sharp hobby knife to trim the covering from the
wing, 1/8" [3.2mm] inside the wing bolt plate outline. Be
careful to not cut into the balsa wood of the wing as this
will weaken it.
❏
5. Glue the wing bolt plate to the wing using 6-minute
epoxy. Wipe off any excess epoxy with a paper towel
dampened with isopropyl alcohol. Hold the wing bolt plate
in place with clamps until the epoxy cures.
❏
6. Drill two 1/4" [6.3mm] holes through the wing bolt
plate using the pre-drilled holes in the wing as a guide. Test
fit the wing on the fuselage, making sure the wing bolts
align with the wing bolt mounts.
❏
1. Trim the covering from the stabilizer slot. Remove the
balsa spacer block at the aft end of the slot.
❏
2. Draw a centerline on both sides of the stabilizer.
Center the stabilizer in the stabilizer slot. Attach a piece of
string with a T-pin to the fuselage centerline as shown.
