37.
Test-fit the motor-
mounting box
between the hori-
zontal engine
bearers. Position the
top of the motor-
mounting box evenly
with the top of the
upper horizontal
engine bearers.
(NOTE: The motor-
mounting box pictured above is unpainted to improve visibility in this instruction
manual. Motor-mounting boxes included with this ARF are supplied prepainted.)
38.
Slightly reposition the motor-mounting box toward the front or rear as necessary
to provide equal distance (approx.
1/2
-inch) between the fronts of the propeller
blades and the trailing edges of the upper and lower wing’s center sections.
39.
Drive 1 cm (
5/16
-inch) long wood screws through the predrilled openings in the horizontal
engine bearers to secure the motor-mounting box to the engine bearers.
40.
Use your radio or a servo tester to center your aileron servos.
41.
Install approx. 1-inch long servo arms on your aileron servos.
(NOTE: If necessary,
remove 1 side from a
2-ended servo arm
supplied with your
servo as pictured at
the right.)
42.
Test-fit your aileron servos and the supplied wooden servo-mounting
pedestals to the servo-hatch covers.
43.
Use epoxy to permanently secure the servo mounting pedestals to the aileron servo hatch covers.
44.
When the epoxy is cured fully, predrill the servo mounting pedestals for your servo’s mounting
screws, apply thin CA to reinforce the openings for the servo mounting screws, and use the
hardware supplied with the servos to mount your aileron servos to their pedestals.
45.
Attach a 10-inch servo extension to each aileron servo.
(NOTE: Help ensure the security of all servo connections
by installing optional Maxford USA servo-extension
safety clips.)
46.
Guide the aileron servo extensions and servo leads into
the servo bays, through the wing panels, and out
through the root ribs of the upper wing panels.
47.
As shown at the right, position the servo arms toward
the outer edge of each wing panel. Use wood screws to
attach the aileron hatch covers to their wing panels.
48.
Connect a 6-inch extension to each of the two identical
ends of a 6-inch Y-harness.
49.
Insert the ends of the Y-harness with these extensions
into the opening at the middle of the top wing’s center
section. Guide the free ends of the 6-inch extensions out
through the opening in the root rib at each side of the
top wing’s center section.
50.
Attach a 10-inch extension to the Y-harness’s servo-like
connector and connect the free end of this extension to
your receiver’s aileron port.

extensions and Y-harnesses you
need may vary depending on the
lengths of the wires supplied with
your servos and where you choose
to position your receiver.)
