Step 1. Carefully remove the aileron from the right wing panel
by pulling straight out with even pressure. Note the location of
the hinges and the aileron torque rod; this will be of assistance
when replacing the aileron onto the wing.
Step 2. Remove all four hinges from the aileron. Flex the hinges
so they move freely.
Step 3. Mix a small amount of 30-minute epoxy. Using either a
mixing stick or a small piece of scrap wood, apply the epoxy
sparingly inside each hinge slot on the aileron. Additionally,
apply a small amount of epoxy to the top and bottom half of each
hinge. Insert the hinges into the aileron until the hinge line is
even with the leading edge of the aileron.
Note: Do NOT apply any epoxy into the aileron torque rod
hole at this time.
Step 4. Lightly coat both ends of the aileron with epoxy; this
will prevent the aileron from becoming fuel soaked.
Step 5. Wipe off any excess epoxy using a paper towel and
rubbing alcohol.
Section 1: Assembling the Wings
• Right wing panel with aileron and hinges
• Left wing panel with aileron and hinges • 30-minute epoxy • Paper towels
• Rubbing alcohol
• Mixing stick/epoxy brush
• Ruler
• Wax paper

Step 6. Mix a small amount of 30-minute epoxy to install the
aileron onto the wing half. Apply epoxy to the top and bottom of
the remaining half of each hinge, as well as the aileron torque
rod hole. Using either a mixing stick or a piece of scrap wood,
apply epoxy inside each hinge slot on the wing.
Step 7. Replace the aileron on the right wing half. Make sure
the hinges are properly aligned and that the aileron torque rod
presses into its respective hole in the aileron. The use of a piece
of wax paper between the torque rod and wing will prevent epoxy
from adhering to the wing. The gap between the aileron and the
wing should remain a constant 1/16′′, or as tight as possible
without restricting the movement of the aileron.
Step 8. Carefully wipe off any excess epoxy using a paper towel
and rubbing alcohol.
Step 9. Repeat the procedures above for the left wing half.
Step 10. Allow the epoxy to cure before proceeding to the next
section.

Step 1. Carefully remove the three individual wing joiners from
the parts bag. If necessary, sand gently to remove any rough
edges.
Step 2. Mix a small amount, approximately 1/4 oz., of 6-minute
epoxy. Using either a mixing stick or epoxy brush, apply the
epoxy to both sides of one of the wing joiners. Place the
epoxied wing joiner on top of one of the two remaining wing
joiners. Stack the remaining wing joiner on top of the epoxied
wing joiner. Align the upper and lower edges of all three wing
joiners, as well as the area which has the slight “V” shape.
Step 3. Clamp the three joiners together using clothespins or
clips. Make sure the joiners remain aligned and the clamps are
firmly attached.
Step 4. Wipe away the excess epoxy using a paper towel and
rubbing alcohol. Be careful not to disturb the alignment of the
wing joiners.
Note: Any excess epoxy should be removed before it cures.
