Section 5: Mounting the Wing
Step 4: Thread the wing hold-down screws into the bottom side
of the blind nuts such that the ends of the screws extend 1/8" of
an inch above the wing saddle.
Step 5: Fit the wing back into position on the fuselage, carefully
sliding the leading edge hardwood locking block into the front
bulkhead slot. Align the wing by measuring the distance from the
wing tip to the center mark as in Step 2 of this section. When the
wing is properly aligned, firmly press downward on the rear center
section of the wing. The wing bolts will make an indentation in the
covering of the wing at the proper location to drill.

Step 6: Using a 1/4" drill bit, drill the exact center of the
marked locations on the bottom of the wing. Be careful that the
drill bit doesn't tear the covering when it exits through the top
surface of the wing.
Step 7: Trial fit the wing into position on the fuselage. Thread
the wing hold-down bolts into the wing and loosely tighten.
Check the alignment of the wing by measuring from a fixed point
on each wing tip to the narrow strip of tape on the fuselage as
you did in Step 2. It may be necessary to slightly enlarge the
holes with a small round file to obtain proper alignment.
