Important: Do not cut into the underlying wood. This will
weaken the structure and could cause failure in flight. As
an option, you can use a soldering iron or hot knife with
light pressure to carefully melt the covering and avoid the
potential of cutting into the wood.
 4. Slide the wing back into position in the fuselage. Check to
make sure the wing is perpendicular (90°) to the fuselage as

  5. Wick thin CA into the joint between the wing and
fuselage. Make sure to apply CA to left, right, top and
bottom to guarantee the wing is glued securely.
Note: Avoid using a CA accelerator to allow the CA to wick
well into the wood of the fuselage and wing. This will provide
the best bond between the two items.
