FINAL WING INSTALLATION
2. Take the bottom wing and locate the hole in
the center of the wing close to the trailing
edge. Carefully remove the covering from
over the hole on both the top and the bot-
tom of the wing.
Next, find the hole in the center of the wing
bolt plate and, again, remove the covering.
3. Align the hole in the wing bolt plate over the
hole in the bottom of the bottom wing.
Draw the outline of the plate on the wing
and, taking care to work 1/4” inside the
outline, remove the covering on the wing in
the area where the plate will rest.
Making sure the holes are aligned, CA glue
the plate onto the wing bottom.
4. Working from inside of the fuselage wing
opening, push the 6-32 blind nut in the hole
in the center of the wing block until it will go
no further.
Take the 6-32 x 1” screw and the #6 x3/4”
washer and screw them through the block
into the blind nut. Tighten until the blind nut
is seated well up into the wing block.
5. Now, temporarily remove the 6-32 screw and
washer and place the bottom wing onto the
fuselage.
Plug the servo extensions from the wing into
the Y-harness.
Insert the two front wing dowels into the bot-
tom of the wing saddle. Then, using the 6-32
screw and washer, screw the back of the
wing to the fuselage
6. With the plane right side up, place the cutout
in the top wing onto the center cabanes.
Next, slide the tabs on both the lower wing
and the top wing into the slots of the I-struts.
The curve of the wing will match the curve of
the bottom of the I-strut.
