o
6) Remove the wing from the wing
saddle. Drill out only the holes in the ply-
wood wing mounting block using a 7/32” drill
bit.
Drilling out only these holes will allow
easier installation of the blind nuts in the
next step.
o
7) Install the two 4mm blind nuts from
underneath the plywood wing hold down
block. The blind nuts can be installed using
pliers by first removing the portion of the balsa
filler block directly above where the blind nuts
are installed. See photo # 2 below.

INSTALLING THE WING BOLT DOUBLER
o
8) Place the wing back into the wing
saddle, aligning the centerline marks. While
holding the wing firmly in place, set the wing
bolt doubler (W-24) in place. The rear edge
of the doubler should be just forward of the
rear edge of the wing saddle and the sides of
the doubler should be flush with the sides of
the fuselage.
o
9) While holding the doubler in place, use
a pen and draw around the doubler to outline
it onto the wing surface.
o
10) Remove the doubler and using a mod-
eling knife, carefully remove the covering
from just inside the outline.
o
11) Mix up a small amount of Kwik Bond
5 Minute Epoxy and use it to glue the wing
doubler to the wing. Allow the epoxy to fully
cure.
o
12) Remove the wing and drill out the
holes through the doubler using a 5/32” drill
bit. Use the holes already drilled through the
wing as a guide and drill down through the
top of the wing.
INSTALLING THE WING
o
13) Place the wing back into the wing
saddle. Secure the wing in place using the
two 4mm x 25mm machine screws and two
4mm washers. See photo # 3 below.
