Great Planes Sequence 1.20 EP/GP ARF - GPMA1232 - Manual (Page 7)

NOTE: Every time wood screws are used throughout
the rest of assembly always perform this procedure of
installing and removing the screws, then hardening the
holes with thin CA.
❏
8. Add a 6" [150mm] servo extension to each aileron
servo. Secure the connections with 1-1/2" [40mm] pieces of
the included heat shrink tubing as shown. Use a heat gun to
shrink the tubing.
❏
9. Mount the servos to the hatches—be certain the servo
arm screws are in place. If you used metal-gear servos, use
a small drop of threadlocker on the threads.
❏
10. Roughen the tabs
on two of the included,
fi berglass control horns.
Same as was done for the
servo arms, if using the
included Great Planes
4-40 ball links, enlarge
the holes. Without any
glue, test fi t the horns
into the slots—be certain
the horns fi t all the way
down and make any adjustments for a proper fi t.
❏
11. Cut and remove the covering from around the base
of the horns.
❏
12. Securely glue the horns in to position with CA.
❏
13. Drill out the screw holes in the hatch cover frame with
a 1/16" [1.6mm] drill.
Refer to this photo while hooking up the ailerons:
❏
14. Guide the aileron servo wires out the end of the wing
and mount the hatch covers with four #2 x 3/8" [9.5mm]
button-head screws—do not use a ball-end hex wrench.
Use a quality, machine-ground hex driver. If you don’t have
a good hex driver you could replace the included button-
heat screws with Phillips screws and washers (not included)
instead. Don’t forget to temporarily remove the hatch covers,
harden the screw holes with thin CA and allow to harden
before remounting the hatches.
