Futaba 6NLK AM - Manual (Page 5)

• Even though the receiver antenna is long, do not cut or
bundle it.
• Install the servos securely. Tighten the mounting screws
until the rubber grommet is crushed slightly. If the screws
are too tight, the cushioning effect will be adversely affect-
ed.
• The crystal can be changed from the outside of the receiver
case. Always use the Futaba transmitter/receiver matched
crystal set to change the band.
• Spare servo horns are supplied. Use them as needed.
• Wrap the receiver in sponge rubber. Waterproof and dust-
proof the receiver by placing it in a plastic bag and wrapping
a rubber band around the open end of the bag. Do the same
with the receiver/servo battery.
• Use the rubber bands wrapped around the receiver to hold
the servo and switch leads.
• After mounting is complete, recheck each part, then check
the range by making the transmitter antenna as short as
possible, extending the receiver antenna fully, and operating
the set from a distance of 20m to 30m. The movement of
each servo should follow the movement of each stick of the
transmitter.
• After mounting and checking are complete, take your model
to the shop where you purchased the set, or to an experienc-
ed radio control modeler, and ask them to teach you how to
handle your radio control set in the proper manner and to
inspect your set-up carefully.
•To enjoy radio control models fully, be sure to observe all
safety standards.
AILERON AND ELEVATOR DUAL (dual rate ON,
OFF) ADJUSTMENT (6NLKonly)
When the dual switch is set to ON, the servo throw is made
smaller by the amount shown by the hatched lines in Fig. 10.
The servo throw can be set from 40% to 100% of the total
travel by adjusting the trimmer next to the switch with a flat
bladed screwdriver. When the dual rate switch is set to OFF,
the throw is normal. When desiring a larger throw, such as for
spins, etc., set the dual rate switch to OFF and adjust the
throw mechanically by horn and rod adjustment. Set the
dual rate switch to on for level flight and adjust the trimmer
for the required amount of throw.
When the dual rate switch is set to OFF, dual rate is set and
the throw becomes large.

1) The splined horn has 25 seg-
ments. The amount of change per
segment is; 360: 25=14.4°
2) The minimum adjustable angle
is determined by the number of
arms or number of the holes. For
four arms, the minimum adjustable
angle is:
To shift the holes center line to
the right (clockwise) relative to
baseline A, shift arm 2 to the po-
sition of arm 1 and set it to the
position closest to baseline A.
(Example] For a four arm horn,
the angular shift per segment is
14.4° . The shift to the right is 90°
- (14.4 x 6 ) = 3.6°
To shift by the same angle in the
opposite direction, use the oppo-
site arm number.
Fig. 14
Arm 3 shift 4.8° to the right, arm
6 shifts 2.4° to the left,and arm 4
shifts 7.2° to the right and left.
For a six arm horn, turn the arm
counterclockwise and set arm 2
to the position of arm 1 . The ad-
justable angle is 60° - (14.4 x 4)
=2.4°.
