Section 10: Mounting the Wing to
the Fuselage
31
Required Parts
• Assembled wing
• Fuselage
• Plywood wing bolt plate (2)
• 1/4-20 x 2" nylon bolts (2)
Required Tools and Adhesives
• 6-minute epoxy
• Screwdriver (slotted)
• Hobby knife
• Felt-tipped pen
Step 1
Locate the plywood wing bolt plate. Align the plate along
the centerline of the wing and trailing edge. Trace around
the plate using a felt-tipped pen.
Hint
: The hole in the wing and hole in the
plate should line up when positioned correctly.
Step 2
Use a hobby knife with a brand new blade to remove
the covering 1/16" inside of the line drawn. Use care
not to cut into the underlying balsa, as this will
weaken the wing structure.
Step 3
Mix 1/2 ounce of 6-minute epoxy and coat both the wing
and plywood plate. Align the plate back onto the wing and
clamp it in position. Remove any excess epoxy using
paper towels and rubbing alcohol.
Caution
: Use scrap plywood under the clamps
to prevent damage to the balsa wing structure.
Step 4
Once the epoxy has fully cured, repeat Steps 1 through 3
for the remaining wing bolt plate.
Step 5
Place the wing onto the fuselage, and check the fit. Make
any adjustments necessary to the wing bolt holes and
attach the wing using the two 1/4-20 x 2" nylon bolts.
