it fore and aft until the fairing is approximately centered. With
a felt-tip pen, trace the outline of the fairing on the fuselage.
❏
4. Use a hobby knife to trim the covering so that you are
trimming about 1/8" [3.2mm] inside of the line you drew. Re-
tack the covering using a sealing iron. Use denatured alcohol
to wipe away the lines.
❏
5. Use 220-grit sandpaper to roughen up the bottom
gluing surface of the strut fairing. Using thick CA or epoxy,
glue the fairing and press it to the fuselage. Make sure that
the carbon strut tube is approximately centered in the hole
in the fairing.
❏
6. Locate the two interplane struts and identify the top
front tab of each strut. Each strut is marked with the letters
“TF” to help you. Another way to identify the top of the strut
is to look for the small lightening hole behind the covering.
❏
7. Use an interplane strut to help you locate the slots in
the top of the lower wings where the strut tabs will install.
The slots are located at the third rib in from the wingtip OR
about half-way in on each wing. You will be cutting between
two closely spaced ribs. The LE of the forward slot is 1-5/8"
[41.3mm] from the LE of the wing. The LE of the rear slot is
3-7/8" [98.4mm] from the LE of the wing. Each slot must be
cut 5/8" [15.9mm] long. If you have not already done so, use
a covering iron set to low to tack down the covering before
you trim. Trim the slots as shown.

8. Use an interplane strut to help you locate the slots in
the bottom of the top wing where the strut tabs will install.
These slots are located at the third rib in from the wingtip.
The LE of the forward slot is 1-5/8" [41.3mm] from the LE of
the wing. The LE of the rear slot is 3-7/8" [98.4mm] from the
LE of the wing. Each slot must be cut 5/8" [15.9mm] long.
Trim the slots as shown.

9. Test fi t the interplane struts to the bottom wing. Make
sure that the tab marked “TF” is pointing up. Slide each strut
forward until it stops.
