Fit the I-Struts in place paying atten-
tion to left and right and top and bot-
tom. The I-Struts have recesses in
them that fit over the tabs in the
wings. Install the four 6-32x3/4”
socket head cap screws in each strut.
With the I-Struts screwed in place,
install the nuts on the screws that
hold the top wing to the cabanes and
tighten. Install the diagonal braces
using the four 6-32x1/2” socket head
cap screws and 6-32 aircraft lock
nuts. After these are tight remove
the screws holding the struts to the
fuselage one at a time and apply
thread locker. Reinstall and tighten.
This sequence of install and tighten-
ing the bolts will make sure that the
struts are aligned and not under
stress.
