❏ 1. Position the wing in the wing saddle and visually align
it with the fuselage. The center joint of the wing should align
with the hole in former F-2.
❏ 2. Transfer the hole location onto the wing LE joiner and
carefully cut out the hole to fit the 1/4" wing dowel.
❏ 3. Round both ends of the 1/4" x 1-1/2" wing dowel. Use
epoxy to glue the wing dowel in the LE joiner and the slot in ribs
W-1. Make sure the dowel is perpendicular to the LE joiner and
protrudes 1/2" out of the forward wing joiner.
❏ 4. After the epoxy cures, reinstall the wing on the fuse.
Use epoxy to glue the die-cut 1/8" plywood wing dowel
doubler to the front of former F-2. Before the epoxy cures,
carefully remove the wing from the fuse.
❏ 5. Place the wing in the wing saddle and visually align it
with the fuselage. Use a tape measure to measure the
distance from the corner of the aileron bay to the center of
the tail post. Then, measure the distance from the other
aileron bay and check if the distances are the same. Adjust
the wing until both distances are equal. When the wing is
perfectly aligned, make reference marks on the wing
trailing edge and former F-3A to help keep the parts aligned
during the next step.
❏ 6. Tape the wing in position so that it cannot move. Use a
5/32" (or #25) drill bit to drill a hole through the wing and wing
bolt plate. Two small 90-degree triangles will help you to align
the drill perpendicular to the top surface of the wing. Important:
Do not allow the wing to shift during this procedure.
❏ 7. Remove the wing and use a 13/64" drill bit to enlarge
the holes in the wing only.
❏ 8. Use a #10-24 tap to cut threads into the wing bolt plate.
After cutting the threads, put a couple of drops of thin CA on
