Great Planes Super Sportster 40 MkII Kit - GPMA0205 - Manual (Page 15)

Important: Sand a slight angle on the inboard edge of the
wing center TE to permit the two pieces to fit flush when
matched to the dihedral angle.
D D 5. Lightly coat the torque rods with petroleum jelly,
then slide the nylon tube back and forth a few times to
lubricate the inside of the tube. This procedure will help
prevent the torque rod from being glued to the tube during
the next step.
D D 6. Coat the center portion of the nylon tubes with 30-
minute epoxy. Then insert the tubes into the grooves of the
wing center TE. Wipe off any epoxy that may squeeze out
with a tissue. Apply epoxy to the forward edges of the wing
center TE, then glue them in position as shown on the
plans. Use masking tape to hold the wing center TE in
position while the epoxy cures.
D 10. While holding an aileron against the inside edge of
the wing center TE, draw a line on it that matches the
inside edge of the wing tip TE. Cut the aileron 1/8" shorter
than the TE opening to allow for covering material.
D 8. Draw a centerline through the two punch marks on the
1/16" die-cut birch ply wing plate. After the wing center TE'S
are completely secure, use 6-minute epoxy to glue the wing
plate in position on the bottom of the wing. Use the
centerline you drew to align the wing plate with the
centerline of the wing. The aft edge of the wing plate must
be flush with the aft edge of the wing center TE. Clamp the
wing plate in position while the epoxy cures.
D 11. Hold the aileron in position, centered in the opening,
then mark the location of the torque rod arms.
D D 12. Drill a 1/8" hole 3/4" deep into the forward edge of
the aileron to accept the torque rod arm.
D 9. Drill two 1/4" holes through the wing center TE using
the holes in the wing plate for the locations.
D D 13. Cut a groove from the hole to the inboard edge of
the aileron to accept the torque rod. Hint: A sharpened
piece of 1/8" brass tubing works well for this task.
