INSTALLING THE WING BOLT DOUBLER

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 in place.
The rear edge of the doubler should be 1/8" forward
of the trailing edge of the wing and the sides of the
doubler should be centered over the centerline of the
wing. See photo # 6 below.

9) While holding the doubler in place, use a pen
and draw around the doubler to outline it onto the
wing surface.
10) Remove the doubler. Using a modeling knife,
carefully remove the covering from just inside the
outline.
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.
12) Remove the wing and drill out the holes
through the doubler using a 1/8" drill bit. Use the
holes already drilled through the wing as a guide.

INSTALLING THE WING

13) Place the wing back into the wing saddle. Se-
cure the wing in place using the two 3mm x 25mm
machine screws and two 3mm flat washers.
PARTS REQUIRED
{1} Molded Plastic Belly Pan
{1} Molded Plastic Belly Pan Doubler

INSTALLING THE BELLY PAN DOUBLER

1) Using a very sharp modeling knife, or lexan
canopy scissors, cut out the belly pan and the belly
pan doubler along their molded scribe lines. See
photo # 7 below.

2) After you have cut out the two parts, use 220
grit sandpaper with a sanding block and lightly sand
the edges of each part. Be careful to keep the edges
straight. Use only enough pressure to remove any
inconsistencies.
3) Using Kwik Bond Thick C/A, carefully glue
the doubler in place at the rear of the belly pan. The
rear edge of the doubler should be flush with the rear
edge of the belly pan. Hold the part in place until the
glue cures. See photo # 8 below.
