Great Planes Cessna 182 Skylane 40 ARF - GPMA1228 - Manual (Page 6)

❏
1. Mark the ailerons left and right and remove them from
the wing panels. Remove the covering from the aileron
servo openings on the bottom of the wing only. Cut 1/8"
[3mm] inside of the opening to allow some material to be
ironed down inside the opening. Use a sealing iron to secure
the covering around the openings.
❏
2. Locate the pre-installed strings in the wing center-
section and wing outer panels. When attaching the wing
outer panels to the wing center-section, the strings for
installing the aileron servos must be moved so they do not
interfere with the fit of the panels. Don’t remove the string
because you will use it to pull your aileron servo cords
through the wing later. Tape each of the strings located in
the aileron servo openings in the outer tip panels to the
bottom of the wing.
❏
3. Locate the hardwood wing joiners. Test fit the wing
joiner into the right wing panel and the right side of the wing
center-section. The joiner is positioned so 1/3 is in the wing
center-section, and 2/3 is in the tip panel. A snug fit of the
joiner is desirable. If the joiner does not fit properly, lightly
sand any uneven surfaces of the joiner edges and sides.
Repeat this step to check the fit of the other wing joiner in
the left wing panel. Label each wing joiner for orientation
and the side that it is to be used on.
❏
4. Drill two 1/2" [13mm] holes in the BOTTOM of the wing
center-section as shown in the drawing. The servo leads will
exit from these holes. The holes are located 2-3/4" [70mm]
back from the front of the wing center-section and 3-1/4"
[83mm] from the edges.
Make a dry run of the following step without using any glue
so you will know how to join your wing together, then
proceed using glue.
❏
5. Un-tape the pre-installed strings in the wing center-
section and the right wing outer panel. Tie the strings
together, being careful not to pull the strings out of the
panels. Note: Don’t remove the strings because you will use
them to pull your aileron servo cords through the wing later.
Tape a piece of wax paper or plan protector over your work
surface. Use a liberal amount of 30-minute epoxy to glue the
wing joiner into the right wing panel and wing center-section.
Apply epoxy to all sides of the joiner, joiner pockets, and
center ribs of both the right wing panel and wing center-
section. Join the wing panel and wing center-section. Use
masking tape to tightly tape the right wing panel and wing
center-section together. Be certain the leading and trailing
edges align. If you have used enough epoxy, it will “ooze”
out from the joint between the two ribs. Wipe off any excess
epoxy from the outside of the wing with a paper towel and
rubbing alcohol. With the wing center-section upright and
flat on your building surface, measure the distance from
your work surface to the tip of the wing outer panel to make
sure you have the correct amount of dihedral as shown in
the sketch. After the epoxy has cured, repeat this step to join
the left wing panel to the wing center-section.
❏
6. Locate the two 1/4" x 2-1/8" [6mm x 54mm] hardwood
wing dowels. Slightly bevel the ends of the dowels. Test fit
the dowels into the wing, making sure they lock into the
holes inside the wing. If necessary, clean out the holes in the
wing using a 1/4" [6mm] drill bit. Use 30-minute epoxy to
glue the dowels into the wing, letting them protrude
3/8" [9.5mm]. Wipe off any excess epoxy using a paper
towel and rubbing alcohol.
