the string. Mark an arrow on the tape, then slide the tape on
the string so the arrow aligns with the wing tip. Swing the
string over to the other tip and see if it aligns with the same
point. If necessary, shift the wing and mark the location of
the tip by adjusting the position of the tape on the string. Do
this until the arrow on the string aligns with both tips.

4. Now that the wing is accurately positioned, fit the belly
pan to the fuselage tightly against the wing. When it is
positioned and fitted properly, use a few drops of thin CA to
tack glue the belly pan sides to the wing. Be careful to neither
move the wing nor glue the wing or belly pan to the fuselage.
❏
5. Remove the wing from the fuselage. Use medium CA
to glue the rest of the belly pan to the wing at all contact
points. HINT: Applying the CA from the inside of the belly
pan helps minimize excess CA outside of the belly pan
which would have to be sanded.
❏
6. Position the wing back on the fuse after all CA is fully
cured. Holding the wing firmly in place on the fuse and
using the punch marks in the wing bolt plate as a guide,
drill two 13/64" holes through the wing bolt plates, the wing
and the bolt block (in the fuselage), keeping the drill
perpendicular to the wing bolt plates and centered in the
holes in the belly pan bottom.
❏
7. Remove the wing from the fuselage and re-drill both
holes in the wing only to 17/64".
❏
8. Use a 1/4-20 tap to cut threads in the bolt block only (in
the fuselage). HINT: A cordless drill makes a great tap driver.
❏
9. Harden the threads in the bolt block with thin CA, then
re-tap the threads after the glue is completely dry.
❏ ❏
10. Mount the wing to the fuse with both wing bolts.
Fit the paper tube through the belly pan bottom and
around the head of the right wing bolt, flush against the
wing bolt plates. Glue the paper tube to the belly pan
bottom and wing bolt plate with medium CA. NOTE: Be
careful not to glue the wing bolts to the wing.
❏ ❏
11. Using a razor saw, cut off the paper tube flush
with the belly pan bottom.
❏
12. Repeat steps 10 and 11 to mount the paper tube
over the other wing bolt. Sand the paper tubes flush with
the belly pan bottom.
❏
13. Remove the wing from the fuse and set aside.
