PRECAUTIONS
NOTE: A separate servo on each aileron will allow use of special transmitter control mixing and differen-
tia/ functions.
• Connect the receiver, servos, switch harness,
etc. as shown in the figure. Extend the trans-
mitter and receiver antennas to their full
length. Turn on the transmitter power switch,
then turn on the receiver power switch. The
servos will go to their neutral position. Move
the transmitter sticks one at a time to check
that each servo follows its control stick move-
ment.
Connect pushrods and linkages to the servos
and check that the direction of travel of each
servo matches the direction of movement of its
control stick. If a servo does not move in the
proper direction, use the servo reversing func-
tion
(See
page
14).
Operate each
servo
to
its
full
extent,
and check
for binding and/or excess slop in the linkage or
pushrod. Unreasonable force on the servo arm
may damage the servo and will drain the bat-
teries very quickly.
•Adjust servo output arms and aircraft control
linkage as necessary so that each servo moves
smoothly throughout its full range of travel,
even when the control stick and trim lever are
operated simultaneously in the same direction.
Be
alert for possible sources of electrical noise.
This set is noise-resistant, but the use of noise-
less parts is recommended.
•When installing the switch harness, make sure
that the switch can move smoothly, to its full
extent in each direction without binding.
Install the switch where it will not be exposed
to engine oil, dust, dirt, etc. The switch can be
installed inside the fuselage and operated from
the outside with a piece of wire.
• Do NOT shorten the receiver antenna or fold it
back
along its length.
•When installing the servos, tighten the mount-
ing screws so that the rubber grommets are
compressed slightly.
If
the
screws
are
too
tight,
the vibration-dampening effect of the grom-
mets will be lost and servo failure may occur.
The crystal can be changed without opening
the receiver case. Always use a Futaba matched
TX/RX crystal set to change frequencies.
Extra servo output arms are supplied. Use them
as needed.
•Use
extension cords where
necessary.
RF
"chokes" are not required with the PCM
receiver.
•Wrap the receiver and the airborne battery
pack separately in foam padding. Padding
should be wrapped loosely for maximum vibra-
tion
protection.
Place
each inside
a
waterproof
plastic bag and secure the end of the bag with a
rubber band.
• Use the rubber
bands wrapped around the
receiver to hold the servo and switch leads.
•After installation and adjustments are com-
plete, perform a range check by collapsing the
transmitter antenna and extending the receiver
to its full length and operating the transmitter
from a distance of 60 to 90 feet from the
receiver (aircraft). The system should operate
normally at this range.
BATTERY CHARGING INSTRUCTIONS
(Transmitter and Receiver Nicd Batteries)
Before operating your system, recharge the Nicd batteries as follows:
•Connect the DIN connector of the FBC-8B (2)
battery charger to the transmitter charging
socket, and connect the 3P connector to the
airborne NR-4J Nicd battery pack and plug the
battery charger into a 120VAC outlet as shown
in the figure.
•The TX and RX LEDs light to show that bat-
teries are being charged. The Nicd batteries can
also be charged through the DSC-CHG cord by
connecting the CHG adaptor to the charger as
shown in the figure. This allows the NR-4J
airborne Nicd pack to be charged without
removing it from the model.
•Normally recharge the battery for about 15
hours. If it has not been used for some time,
discharge and recharge it two or three times,
then charge it a full 15 hours.
•The
amount of time
remaining
before the bat-
teries must be recharged can be estimated by
checking the integrated timer at the moment
the TX battery alarm sounds (antenna ex-
tended).
• Leaving batteries in the discharged state for a
long time will adversely affect their capacity
and life.
•The TX and RX Nicd batteries can be charged
simultaneously or independently.
•A fully-charged TX battery can be used for
about 10 flights of 10 minutes each. The air-
borne NR-4J Nicd battery pack can be used
for about 7 flights when 6 servos are used and
about 4 flights when 10 servos are used.
• The DSC (Direct Servo Controller)
system connects the signals from
the transmitter directly to terminal
C of the receiver through the DSC
cord and controls the servos with-
out transmitting radio waves. \\ is
extremely convenient when other
dyers are on the same frequency,
or during contests, etc.
When the DIN connector of the
DSC cord is connected to the DSC
socket, the power to the encoder of
the transmitter is turned ON auto-
matically The transmitter power
switch is left OFF.
• When not using the DSC, discon-
nect the DIN connector to reduce
battery drain.
To operate the servos, turn on the
airborne switch (only).
•When the DSC cord
is connected, the receiver
power supply voltage
is measured
(no load).
The voltage is displayed
by "Ex" on the lower
right side of the initial
LCD
screen.

TIMER
The TIMER function can be used to monitor flying time, fuel consumption, at contests,
etc. Four different timing functions are available: Up Timer, Down Timer, Rhythmic Timer,
and Total (Integrating) Timer.
Timer Functions
1) Up Timer This timer counts up from zero in
1 second steps. Its maximum count is 59:59.
When the alarm time is set, a buzzer begins to
sound 10 seconds before the set time is up.
The buzzer also sounds at each 1 minute
interval. When the time reaches 59:59, timing
restarts from 00:00.
2) Down Timer This timer counts down from
the set time in 1 second steps. Operation is
otherwise the same as the Up Timer.
3) Rhythmic Timer This is a 0.1 second cyclic
timer. A buzzer sounds at each set alarm
interval. When the set alarm interval elapses,
the counting automatically restarts.

TACHO METER
Tachometer
The tachometer function is used to measure the speed on one to five-bladed propellers, etc. Speed (rpm) is
measured up to a maximum of 50,000 rpm (in 20 rpm increments).
Setting Method
1) Display the standard screen, and press the
TAC program key.
2) Press program key to to select the
number of blades.
Ex: for a two-bladed propeller.
3) Measure the speed by pointing the built-in
sensor on the transmitter (center of the left
side panel) at the front or rear of the propeller
disc from a distance of 8 to 12 inches. Be sure
the model is restrained by an assistant, and be
very careful of the rotating propeller.
Allow a few seconds for the display to stabi-
lize, then read the measured value. Maximum
speed range is 50,000 rpm.
Low Battery Warning
Low Battery Warning
This function operates when the transmitter
Nicd battery voltage drops below 8.5 volts. The
characters "LOW BATTERY" blink on the
screen, and a buzzer sounds. When this occurs,
land immediately and recharge or replace the
Nicd battery pack.
Back Up Warning
Back Up Warning
When the stored data is lost, the characters
"BACK UP" blink on the screen and a buzzer
sounds. When the power switch is turned on
again, the error display disappears and all the
settings return to the factory-set values. When
a Back Up error occurs, the back-up lithium

FAIL SAFE
Fail Safe
Fail
Safe
and
Hold
Functions
The HOLD (Hold) and F/S (Failsafe) functions
are designed to allow the aircraft to "fly
through"
a
momentary
loss
of
signal
or
very
strong interference, rather than experiencing the
familiar
"glitch"
as
the
servos
react
violently
to
the unwanted signal. These functions cannot be
expected to prevent a crash however, if the
normal signal interruption is of sufficient dura-
tion.
The HOLD function stops the servo at the posi-
tion held just before the normal signal is lost.
When a normal signal is again received, the Hold
function is released.
The FAILSAFE
function
will
move
a
servo
to
a pre-set position when the normal signal is
interrupted for 1 second or longer (The system
will remain in HOLD for the first 1 second of
signal loss). When a normal signal resumes, FAIL-
SAFE is released.
BFS
(Battery Fail Safe) Function
The BFS function moves the throttle (CH3)
servo to the pre-set Fail Safe position when the
airborne power supply is nearly exhausted. If no
Fail Safe position has been set, the throttle servo
will move to medium slow (neutral).
BFS can
be
released
by lowering
the
throttle
stick past the
release
point
(adjustable),
or
with
the CH9 switch. Throttle control is then regained
for about 30 seconds. At the end of 30 seconds,
BFS
will re-engage and the throttle will again
move to the Fail Safe position. Whenever BFS

ADJUSTMENTS AND FLIGHT TECHNIQUES
ADJUSTABLE TRAVEL VOLUME
• The ATV function is used to adjust servo travel limits. Servo travel can be adjusted independently in each
direction from neutral. Adjustment from 30% to 110% of normal full travel (throw) is possible.
• NOTE: When servo travel is changed by ATV, the limits of trim throw and the Dual Rate ON (Low Rate)
limits are increased or reduced by the same percentage.
• ATV limits are displayed by a bar graph and numbers. The point at which the cursor moves from left to
right, as the stick or lever is moved, is the electrical neutral point of that channel.
Setting Method
1) Select the EDIT screen, then select the ATV

In the example shown, the CH1 (Aileron) right throw is reduced to 90%.
In the bar graph illustration below, the right
hand throw is reduced to 50% of normal, while
the left hand throw is set to 100%. Note that on

Trim throw limits are also reduced to 50% of

[16]
ADJUSTABLE FUNCTION RATE
AFR is a servo endpoint limiting function, similar to ATV with three exception:
1. AFR limits only the Dual Rate OFF (High
Rate) servo travel. Trim throw and Dual Rate
ON (Low Rate) limits are unaffected (unless
AFR is reduced below the D/R ON limit).
2. AFR can be used with mixing functions to
adjust more than one channel simultaneously.
For example, let's assume that the Aileron
Differential mixing program is activated, and
that CH1 controls the right aileron and CH7
controls the left aileron. AFR can be used to
adjust the aileron control response because
the CH1 and CH7 servos will be affected
simultaneously (Ex: Reducing the left aileron
AFR will reduce the left hand servo (CH7) UP
throw and the right hand servo (CH1) DOWN
throw simultaneously.).
With ATV, the CH1 servo and CH7 servo
throws in the above example would have to be
adjusted separately.
3. AFR sub trimmers are available on the front
trimmer panel for Aileron and Elevator AFR.
These allow quicker field adjustments in con-
trol response without the necessity of going
through the usual programming steps. Adjust-
ments can even be made during flight (by an
assistant). Maximum adjustment available on
the sub trimmers is ±25% of the amount of
travel set on the AFR program screen.
Setting Method
1) The setting method
for AFR is the same as for
ATV (See page 16).
2) Select the EDIT screen and press the AFR pro-
gram key.
3) The percentage figures displayed on the
extreme left and right sides of the screen
(CH1 and CH2 only) show the total amount
of travel actually set (The amount set with the

4) When the sub trimmers are turned slowly, a
tone will sound at the exact neutral position.
With the sub trimmer in neutral, the total
travel will equal that set with the program
keys.
In the bar graph illustration below, the right
hand throw is reduced to 70% of normal throw
by AFR. Note that the Dual Rate ON (Low
Rate)

ADJUSTMENTS AND FLIGHT TECHNIQUES
DUAL RATE
Dual Rate functions allow the modeler to switch servo travel limits in flight, thus varying
the control sensitivity for different flight conditions or maneuvers.
• Dual Rate functions are available on CH1 (Aileron), CH2 (Elevator), and CH4 (Rudder).
• Dual Rate ON (Low Rate) limits can be adjusted from 30% to 100% of full throw.

• Dual Rate ON limits can be adjusted independently in each direction from neutral.
•There are three D/R ON/OFF Switches. Control of the three D/R functions can be assigned to these
switches in any combination the modeler desires, or D/R functions can be switched ON and OFF auto-

Exponential Mixing Trim Parameter Model End
EXPONENTIAL/VTR
Exponential or VTR functions can be used to change the servo response curve from the
normal linear operation. This can be very helpful if control response is either sluggish or too
sensitive near the neutral position. Maximum servo deflection limits (set by ATV and/or
A FR) remain the same.

used, when desired, on "neutralizing" controls
such as AIL, ELEV. and RUD.
The TYPE 2 Curve is exponential in one direc-
tion over the full stroke of the control stick or
lever. This type is normally used with functions
such as THR.
• The amount of exponential can be varied from
0% to 100% in 4% steps. By using positive or
negative exponential with either the TYPE 1 or
TYPE 2 EXPO Curves, a total of four different
types of Exponential control response can be
selected.
Exponential control is available on CH1 to
CH8.
• Two different types of Exponential response
curves can be selected.
The TYPE 1 Curve is symmetrical in both
directions from neutral. This type is generally
[20]
TYPE 1 Positive TYPE 2 Positive
With this type of curve, control response will be made
more sensitive near neutral and less sensitive as the stick
is deflected farther towards its extreme limits.
With this type of curve, response will be most sensitive
at the LOW end of control stick travel, and decrease as
the stick is moved toward HIGH.
TYPE 1 Negative
TYPE 2 Negative
With this type of curve, control response wilt be
"softer" around neutral and increase as the stick is
deflected farther.
With this curve, the response is less at the LOW end and
steadily increases as the stick is moved toward HIGH.
• When VTR is used, servo response remains linear, but the response is automatically switched to a higher
rate at a certain (adjustable) point in the control stick deflection.
• The initial response rate is the same as the Dual Rate ON rate (See page
18).

EXAMPLES OF PROGRAMABLE MIXING
Programmable Mixing combinations are extremely versatile and can be as complex as desired,
limited only by the modeler's needs and imagination. A few/examples of how mixing func-
tions can be used are shown below:
Eliminating Unwanted Control Interactions
Adverse control interactions (caused by trim,
model inaccuracies, etc.) can be compensated for
automatically, with the use of the Programmable
Mixing function.
As an example, let's presume that when top rud-
der is applied during "knife-edge" flight, an un-
wanted movement toward the top of the aircraft
occurs. We can use a Programable Mixing circuit
to automatically apply a small amount of DOWN
Elevator control with the application of top

ADJUSTMENTS AND FLIGHT TECHNIQUES
SERVO (Transmitter Test Mode)
Transmitter control movements are shown on a bar graph representing servo movement for
channels 1 through 8. The center of the graph is the neutral position. The bottom half in-
dicates counterclockwise servo rotation and the top half represents clockwise rotation.
Setting Method
1) Select the EDIT screen and move the cursor
to Line 3 with the cursor key, then dis-
play the SERVO screen by pressing the
2) Bar graphs proportional to the servo throw
can be observed by operating the control
sticks, levers, and switches of each channel of
the transmitter (1 to 8). This can be used to
test the performance of the transmitter, and
check the effect of new settings and data
in-
puts.

•SPLINED HORN
The splined horns allow adjustment of the servo neutral
position at the servo horn.
Neutral position adjustment
a) Angle divisions
To shift the holes center line to the right (clockwise)
relative to baseline A, shift arm 2 to the position 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° - (14.4x6) = 3.6°
1) The splined horn has
25
segments. 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 holes. For four arms,
the minimum adjustable angle is:
b) Effect
To shift by the same angle in the opposite direction, use
the opposite arm number.
For a six arm horn, turn the arm counterclockwise and
set arm 2 to the position of arm 1.
The adjustable angle is 60 - (14.4 x 4) = 2.4°.
Arm 3 shifts 4.8° to the right, arm 6 shifts 2.to the
left, and arm 4 shifts 7.2° to the right and left.
The following splined horns are optional.
