PRECAUTIONS

NOTE: A separate servo on each aileron will allow use of special transmitter control mixing and differentia/ functions.

• Connect the receiver, servos, switch harness, etc. as shown in the figure. Extend the transmitter 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 movement.

• 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 function (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 batteries 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 insta lling the servos, tighten the mounting screws so that the rubber grommets are compressed slightly. If the screws are too tight, the vibration-dampening effect of the grommets 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 vibration 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 complete, 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 batteries 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,

TX (Transmitter)

Charging Method

AC-120V

Charger FBC-8B (2)

RX (Receiver)

then charge it a full 15 hours.

•The amount of time remaining before the batteries must be recharged can be estimated by checking the integrated timer at the moment the TX battery alarm sounds (antenna extended).

•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 simultaneouslyorindependently.

•A fully-charged TX battery can be used for about 10 flights of 10 minutes each. The airborne 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.

Make this connection when using the DSC.

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.

4) Total (Integrating) Timer This timer records the total transmitter ON time. It is very useful for estimating remaining Nicd battery capacity and monitoring total flying time. Maximum count is 59:59:59.

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 stabilize, 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 battery is probably dead, or there is trouble in the system. To locate the cause, call your Futaba service center. The back up lithium battery life depends on the usage state, but is about 5 years.

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 duration.

The HOLD function stops the servo at the position 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, FAILSAFE 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 engages, land the aircraft as quickly as possible and recharge or replace the Nicd battery pack.

[14]

Fail Safe and Hold General Instructions

Fail Safe

•F/S or HOLD can be selected for each channel (1 to 8).

•Channels selected for HOLD will remain in

HOLD until a normal signal resumes. Those selected for F/S will move to their pre-set positions after 1 second of signal interruption.

•F/S SET simultaneously stores the desired Fail Safe position in the transmitter memory and

sends it to the receiver.

•The F/S data is automatically sent to the receiver when the transmitter is first turned ON and at one minute intervals as long as the transmitter is left on.

•The F/S position can be checked with the CHK programkey.

•Only the Throttle channel (CH3) can be set for Battery Fail Safe.

Fail Safe Setting

1)Display the EDIT screen, then select the FAILSAFE screen by pressing the F/S pro-

gram key.
2) Move	the cursor to the		desired channel with
the	and	cursor	keys	and select
HOLD or F/S for each channel by pressing the
or		program key. When		Failsafe is

selected, the number 50 will appear below the appropriate channel on the POSI-(%) line of the FAILSAFE screen.

3) Store the Failsafe positions in the transmitter memory by pressing the key while holding the stick or lever of the channel being set in the desired Failsafe position. Simultaneously, the data is also transmitted to the receiver and is automatically re-transmitted at one minute intervals.

Battery Fail Safe Setting

1)Set the Failsafe position on the throttle channel (CH3) as described above. A position slightly above the minimum engine idle speed is recommended.

2)BFS Release Point Setting (When THR is

designated as the release channel)

• Move the cursor to the B/FS-RESET line of the FAILSAFE screen with the

cursor key.

•Select the BFS release channel with the or program key.

•Set the throttle stick to the desired BFS

release point and press the program key. This designates CH3 (Throttle) as the release channel and sets the stick release point simultaneously.

3)To release BFS by the CH9 switch, press the program key.

•BFS can be released by the CH9 switch only when the switch is moved to the upper position. If the CH9 switch is in the lower position, BFS cannot be released.

•In the BFS release state, the characters 0%- RESET are displayed on the B/FS-RESET line of the FAILSAFE screen.

4)If Battery Fail Safe is not desired, press the

program key (when the cursor is on the B/FS-RESET line). The BFS function will then be disabled.

In the example below, (Throttle) was set to Fail Safe and Battery Fail Safe.

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 program screen by pressing the program key.

2)Rate data (endpoint limits) for Channels 1 to

4 is displayed on the screen. To display and adjust Channels 5 to 8, press theprogram key. Rate data for Channels 5 to 8 will be

displayed.

3)Select the channel to be set with the and

cursor keys.

4)Operate the control stick, lever, or switch of the channel to be adjusted to its maximum

extent in the desired direction. The cursor will automatically move to the left or right confirming the direction to be set.

5)Servo endpoint limits can be set by pressing the and program keys while holding the appropriate stick or lever in the same direction. Pressing the program key will return the set limit to 100%.

6)When you are finished, press the key to return to the EDIT screen.

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 the right side. Dual Rate ON (Low Rate) and Trim throw limits are also reduced to 50% of normal.
