3. Look closely on the top of the bottom wing and you
will find a small pin hole locating the blind nuts for the
cabane mounting bolts. Cut the covering from each of the
holes. Note: 4-40 blind nuts have been installed in the wing
for all of the cabane mounting bolts. All of the blind nuts are
glued into the wing and have a small wood plate backing
them up. It is possible that a blind nut could have a bit of glue
in the threads. In most cases the installation of the bolt
should free the glue. If not, run a 4-40 tap through the
threads to clear the glue.
4. Mount the bottom wing cabane brackets in each of
the holes in the right wing panel with a 4-40 x 1/2" [13mm]
socket head cap screw and a #4 lock washer. Do not fully
tighten the bracket to the wing yet.
5. Position the "N" strut to the bracket. Located on the
strut is a piece of masking tape with an arrow that indicates
the top, front of the strut.
6. Attach the strut to the bracket as shown with a 4-40
x 1/2" [13mm] phillips head screw, a #4 washer and a 4-40
nylon lock nut.
7. If you have not been doing the bracket installation on
both the right and left wing, go back and repeat steps 3-6 for
the left wing panel.
