4. Center the wing side to side, leaving equal space
between the fuse sides and the wing at the leading edge.
❏
5. Making sure to keep the wing centered and in the
saddle, tack glue the dowel disks (part #37) in place with
thin CA. Note: DO NOT GLUE THE DOWEL DISKS TO
THE WING DOWELS.
❏
6. Remove the wing and permanently glue the dowel
disks in place with thin CA.
❏
7. Stick a T-pin through the center of the aft end of the
fuselage bottom. Tie a string to the T-pin. Pull the string to
the TE of the wing tip and put a piece of masking tape on
the string at the wing tip. 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.
❏
9. Make two alignment marks on the TE of the wing
where it meets the fuse. Note: You will build the belly pan
onto the wing before the wing gets mounted to the fuse, so
it is important the wing stay straight in the fuse for the next
steps until the wing is bolted to the fuse.
❏ 10. Cover the area of the belly pan with a Great Planes
Plan Protector or waxed paper. Pin the aft belly pan
former (part #22) to the fuse.
❏
11. Fit the belly pan sides (part #18) and middle belly
pan former (part #20) in place, holding the front of the
belly pan sides at equal distances from the fuse sides.
When satisfied with the fit, glue the sides to both formers.
❏
12. Glue the die-cut 1/8" ply forward belly pan former
(part #19) to the belly pan sides. The sides will need to be
bent inward to fit the former, be sure to keep the former
centered on the fuse sides.
