5. Remove the tape holding the end of the servo wire
draw-strings inside the servo bays. Tie these ends to the
servo connectors and use the string to pull the servo leads
through the wing ribs.
❏
6. You can either glue the servo bay covers in place or use
eight 2.6 x 8 mm [7/64" x 5/16"] self-tapping screws. It is
recommended to glue the covers in place for a cleaner look.
However, the servos will be more difficult to replace should it
be necessary in the future. If you use screws, position the
covers onto the wing panels and drill 5/64" [2 mm] holes in
each of the four corners of the covers. Thread a 2.6 x 8 mm
[7/64" x 5/16"] screw into each hole and back it out. Apply a
drop of thin CA glue to the holes and allow it to fully harden.
Secure the covers to the wings with the screws.
❏
7. Make a mark 7/16" [11 mm] long on each aileron
perpendicular to the aileron hinge and in line with the outer
hole of the servo horn.
❏
8. Trim the bottom tabs of two control horns so that only
5/32" [4 mm] remains.
❏
9. Use a hobby knife along the marks you made to remove
enough material to accommodate the control horn tabs. Do not
cut all the way through the ailerons. Test fit the control horns
into the slots, being sure the horns fully seat onto the ailerons.
When satisfied with their fit, coat the control horn tabs with
medium CA glue and press them into place.
❏
10. Double check that the servo horns are perpendicular
to the servos. Fit the Z-bend in the 2-7/8" [73 mm] aileron
pushrod into the outer hole of the servo horn. While holding
the aileron in the neutral position, stick a piece of masking
tape onto the pushrod where it crosses the holes in the
control horn.
