5. Insert the four 3 x 12mm
alignment pins
into the wing
struts, then securely glue them into place with a few drops
of thin CA.

6. Thread the four M3 x 35 threaded studs into both wings.
If any of the studs are diffi cult to thread in, you can thread
two knurled thumb nuts onto the stud to act as a stop-nut
and turn them to turn in the stud. The studs should stop
when they get about halfway in.

7. Mark the recommended C.G. on the bottom of the
top
wing 4-5/8" [117mm] back from the leading edge at the
middle of the wing. Also mark the forward and aft range 4"
[102mm] and 5-1/4" [133mm] back. One good way to mark
the C.G. is with narrow strips of tape so you can feel the
lines with your fi ngers when suspending the plane during
the C.G. check later.
