and 2 S

LIDERS

; completely assignable in most applications.

•

Trainer system includes the “functional” (

FUNC) setting, which allows the student to use the 9C’s mixing, helicopter, and other programming functions even with a 4-channel buddy box. (Optional trainer cord required.)

•

Transmits in both FM ( PPM) and PCM by selecting modulation/cycling transmitter. Requires receiver of proper modulation.

•

Permanent memory storage via EEPROM with no backup battery to service or have fail.

•

9CA transmitter features airplane friendly switch layout, with the trainer switch at the left hand, and a notched throttle to minimize throttle changes with rudder input. Defaults to ACRO MODEL TYPE.

•

9CH transmitter features helicopter-friendly switch layout, with idle-up and throttle hold switches at the left hand, and a smooth, ratchet-less (unsprung) throttle for perfect hovering. Defaults to HELI(SW1) MODEL TYPE.

•

Change transmitter mode from mode 2 to modes 1, 3, or 4. (See P. 15)

7

MODULE: 72TP-FM

•

Module may be easily removed and a module on a different channel (or even band) reinserted to change the frequency on which the 9C transmits.

•

Module transmits both FM ( PPM) and PCM. No need for a second module.

•

All transmission circuitry is included in the module, so no retuning is needed when changing channels or even bands.

•

Frequency band is changed by inserting a module on the proper band, including for international or ground model use.

•

In North America it is against FCC regulation to change the crystal within the transmitter module to a different channel. All such transmitter crystal changes must be performed by a certified radio technician. Failure to properly tune a system to its new channel may result in decreased range and may also result in interference to other types of frequency users on adjoining channels. Doing so also voids your AMA insurance.

•

The FSS synthesized module for the 9Z family of radios is NOT compatible with the 9C.

•

Radio system beeps and RF

LIGHT

goes out to indicate module is not installed and radio is not transmitting.

•

Non-Futaba brand modules are not FCC certified for use with this radio and therefore are against FCC regulation to use.

Doing so also voids your AMA insurance.

•

TJ75FM modules may also be used with the 9C for ground use models such as robotics, rocketry, trains, cars, and boats.

RECEIVER: R138/R148/R149

•

The R138 or R148 FM 8-channel or the R149 PCM 9-channel receiver included with your system is a high-sensitivity narrow-band dual-conversion receiver.

•

Note that your 9C transmitter is capable of transmission on both PPM (FM) and PCM with just a simple programming change and just turning the transmitter off and back on. (See p. 28.)

•

Any Futaba narrow band FM receiver (all produced after 1991) on the correct frequency band and frequency may be used with the 9C.

•

Any Futaba PCM 1024 receiver on the right frequency band and frequency may be used with the 9C (all 1024 receivers say PCM1024; receivers which say PCM but not 1024 are 512 resolution and not compatible).

NEVER attempt to change a receiver’s band by simply changing crystal (IE removing a 72MHz crystal and inserting a 75MHz crystal). A receiver that has a crystal installed from a different frequency band without retuning will not receive properly and will have dramatically decreased range.

•

In North America the receiver included with this system may have its frequency changed by simply changing the crystal as long as it remains in the same half the band. A low band receiver between channels 11 and 35 may be changed to any other channel between 11 and 35 without requiring any tuning. A high band receiver between channels 36 and 60 may similarly be changed. Receivers being changed from a high band channel to a low band or vice versa require proper tuning and service by the Futaba Service Center.

SERVOS

• Please see technical specifications page for specifics on the servos included with your system.

• The included receiver is compatible with all J-plug Futaba servos, including retract, winch, and digital servos.

The following additional accessories are available from your dealer. Refer to a Futaba catalog for more information:

•

CAMPac Memory module - the optional DP-16K CAMPac increases your model storage capability (to 14 models from

8) and allows you to transfer programs to another 9C transmitter. Note that data cannot be transferred to/from any other model of transmitter (i.e. 8U, 9Z, etc).

Insertion of a CAMPac containing data of a different transmitter type (ex: 9Z) will result in a complete

CAMPac data reset and loss of all data.

•

NT8S Transmitter battery pack - the (600mAh) transmitter Ni-Cd battery pack may be easily exchanged with a fresh one to provide enough capacity for extended flying sessions.

•

Trainer cord - the optional training cord may be used to help a beginning pilot learn to fly easily by placing the instructor on a separate transmitter. Note that the 9C transmitter may be connected to another 9C system, as well as to many other models of Futaba transmitters. The 9C transmitter uses the newer rectangular type cord plug. Both new-to-new and new-to-round plug style trainer cords are available.

•

FTA8 Neckstrap - a neckstrap may be connected to your T9C system to make it easier to handle and improve your flying precision, since your hands won’t need to support the transmitter’s weight.

•

Y-harnesses, servo extensions, etc - Genuine Futaba extensions and Y-harnesses, including a heavy-duty version with heavier wire, are available to aid in your larger model and other installations.

•

5-cell (6.0V) receiver battery packs - All Futaba airborne equipment (except that which is specifically labeled otherwise) is designed to work with 4.8V (Ni-Cd 4 cells) or 6.0V (Ni-Cd 5 cells or alkaline 4 cells). Using a 6.0V pack increases the current flow to the servos, which accelerates their rate of response and their torque. However, because of this faster current draw, a 5cell battery pack of the same mAh rating will last approximately ¾ the time of a 4-cell pack.

•

R309DPS - Synthesized receiver which can be changed to any 72MHz frequency with the turn of 2 dials, no tuning needed.

•

Gyros - a variety of genuine Futaba gyros are available for your aircraft or helicopter needs. See p. 64 for aircraft or p. 89 for helicopter gyro information.

•

Governor (GV1) - for helicopter use. Automatically adjusts throttle servo position to maintain a constant head speed regardless of blade pitch, load, weather, etc. See p. 89 for details.

•

DSC Cord - allows setup and testing without transmitting. Requires DSC compatible receiver (R149DP or R309DPS) and DSC cord. With Transmitter and Receiver off, plug cord into trainer port then, into receiver battery slot. All programing and setup may be done in this manner without transmitting.

•

TP72FM modules - additional modules on other frequencies within the 50MHz (licensed operators only) and 72 MHz bands may be purchased to utilize your transmitter with receivers on other frequencies. Additionally, the TK and

TJ75MHz modules may be used with the 9C. (See p.8)

•

Receivers - various models of receivers may be purchased for use in other models. (See p. 8.)

SWITCH ASSIGNMENT TABLE

•

The factory default functions activated by the switches and knobs for a Mode 2 transmitter are shown below.

•

Most 9C functions may be reassigned to non-default positions quickly and easily.

•

Basic control assignments of channels 5-9 are quickly adjustable in AUX-CH (see pp. 39). For example, the channel 5 servo, which defaults to S

WITCH

E for retract use, can easily be unassigned ( NULL) to allow for easy use as a second rudder servo in a mix, or to a slider or dial for bomb door or other control.

•

Note that most functions need to be activated in the programming to operate.

•

Mode 1 transmitter functions are similar but reverse certain switch commands. Always check that you have the desired switch assignment for each function during set up.

CHARGING THE Ni-Cd BATTERIES

Charging Your System’s Batteries

1. Connect the transmitter charging jack and airborne Ni-Cd batteries to the transmitter and receiver connectors of the charger.

2. Plug the charger into a wall socket.

3. Check that the charger LED lights.

Charger

The initial charge, and any charge after a complete discharge, should be at least 18 hours to ensure full charge. The batteries should be left on charge for about 15 hours when recharging the standard NR-4J, NR4F1500 and NT8S600B Ni-Cd batteries.

TX: Transmitter charging indicator

RX: Receiver charging indicator

To transmitter charging jack

Receiver Ni-Cd battery

We recommend charging the batteries with the charger

supplied with your system. Note that the use of a fast charger

may damage the batteries by overheating and dramatically reduce their lifetime.

You should fully discharge your system’s Ni-Cd batteries periodically to prevent a condition called memory. For

example, if you only make two flights each session, or you regularly use only a small amount of the batteries capacity, the memory effect can reduce the actual capacity even if the battery is fully charged. You can cycle your batteries with a commercial cycling unit*, or by leaving the system on and exercising the servos by moving the transmitter sticks until the transmitter shuts itself off. Cycling should be done every four to eight weeks, even during the winter or periods of long storage. Keep track of the batteries capacity during cycling; if there is a noticeable change, you may need to replace the batteries.

*Note that the 9C transmitter system has electronic protection from overcharging and reverse polarity via a poli-switch.

It does NOT have a diode in the charge circuit and may be discharged/peak charged with the battery in the transmitter.

DO NOT attempt to charge your 8-cell transmitter pack on the 4-cell receiver plug of the wall charger!

Adjusting the length of the non-slip control sticks

Stick tip A Locking piece B

You may change the length of the control sticks to make your transmitter more comfortable to hold and operate. To lengthen or shorten your transmitter’s sticks, first unlock the stick tip by holding locking piece B and turning stick tip A counterclockwise. Next, move the locking piece B up or down (to lengthen or shorten). When the length feels comfortable, lock the position by turning locking piece B counterclockwise.

Stick lever tension adjustment

Elevator

Stick Stick

Rudder

Mode 2 transmitter with rear cover removed.

You may adjust the tension of your sticks to provide the feel that you prefer for flying. To adjust your springs, you’ll have to remove the rear case of the transmitter. First, remove the battery cover on the rear of the transmitter. Next, unplug the battery wire, and remove the battery and RF module from the transmitter. While you are removing the RF module, pay attention to the location of the pins that plug into the back of the module. Next, using a screwdriver, remove the four screws that hold the transmitter’s rear cover in position, and put them in a safe place. Gently ease off the transmitter’s rear cover.

Now you’ll see the view shown in the figure above.

Using a small Phillips screwdriver, rotate the adjusting screw for each stick for the desired spring tension. The tension increases when the adjusting screw is turned clockwise.

When you are satisfied with the spring tensions, reattach the transmitter's rear cover. Check that the upper printed circuit board is on its locating pins, then very carefully reinstall the rear cover being mindful to guide the RF module connector pins through the slot in the case. When the cover is properly in place, reinstall and tighten the four screws. Reinstall the battery, cover and module.

Adjusting Display Contrast

To adjust the display contrast, from the home menu press and hold the

End button.

Turn the dial while still holding the menu button: clockwise to brighten counterclockwise to darken the display

Let go of the dial and the button.

Changing Modes:

Hold down the Mode and End buttons while turning on the Transmitter. The screen reads "STK-MODE". Change this to the correct mode. Note that this will NOT change the throttle and elevator ratchets, etc. Those are mechanical changes that must be done by a service center.

RADIO INSTALLATION

While you are installing the battery, receiver, switch harness and servos into your model’s fuselage, please pay attention to the following guidelines:

Wood screw

Rubber grommet

Brass eyelet

Servo mount or rail

Use the supplied rubber grommets when you mount each servo. Be sure not to

over-tighten the screws. If any portion of the servo case directly contacts the fuselage or

the servo rails, the rubber grommets will not dampen the vibration, which can cause mechanical wear and servo failure.

Servo Throw

Once you have installed the servos, operate each one over its full travel and check that the pushrod and output

arms do not bind or collide with each other, even at extreme trim settings. Check to see that each control linkage does

not require undue force to move (if you hear a servo buzzing when there is no transmitter control motion, most likely there is too much friction in the control or pushrod). Even though the servo will tolerate loads, any unnecessary load applied to the servo arm will drain the battery pack quickly.

Switch Harness Installation

When you are ready to install the switch harness, remove the switch cover and use it as a template to cut screw holes and a rectangular hole slightly larger than the full stroke of the switch. Choose a switch location on the opposite side of the fuselage from the engine exhaust pipe, and pick a location where it can’t be inadvertently turned on or off during handling or storage. Install the switch so it moves without restriction and snaps from ON to OFF and vice versa.

Receiver Antenna

It is normal for the receiver antenna to be longer than the fuselage.

DO NOT cut or fold it back on itself — cutting or folding changes the electrical length of the antenna and may

reduce range. Secure the antenna to the top of the vertical fin, and let the excess wire length trail behind. You may run the antenna inside of a non-metallic housing within the fuselage, but range may suffer if the antenna is located near metal or carbon fiber pushrods or cables. Be sure to perform a range check before flying.

Receiver Notes

When you insert servo, switch or battery connectors into the receiver, note that each plastic housing has an alignment tab. Be sure the alignment tab is oriented properly before inserting the connector. To remove a connector from the receiver, pull on the connector housing rather than the wires.

If your aileron servo (or others) are too far away to plug into the receiver, use an aileron extension cord to extend the length

of the servo lead. Additional Futaba extension cords of varying lengths are available from your hobby dealer. Always use an

extension of the proper length. Avoid plugging multiple extensions together to attain your desired length. If distance is greater than

18” or multiple or high current draw servos are being used, use Futaba Heavy-Duty servo extensions.

Receiver Vibration and Waterproofing

The receiver contains precision electronic parts. Be sure to avoid vibration, shock, and temperature extremes.

For protection, wrap the receiver in foam rubber or other vibration-absorbing materials. It is also a good idea

to waterproof the receiver by placing it in a plastic bag and securing the open end of the bag with a rubber band before wrapping it with foam rubber. If you accidentally get moisture or fuel inside the receiver, you may experience intermittent operation or a crash. If in doubt, send the receiver for service.

Using

FLAPERON (ACRO/GLID):

The

FLAPERON mixing function uses one servo on each of the two ailerons, and uses them for both aileron and flap function. For flap effect, the ailerons raise/lower simultaneously.

Of course, aileron function (moving in opposite directions) is also performed.

Once

FLAPERON is activated, any time you program CH6 or “flap” (ie. FLAP-ELEVATOR mixing), the radio commands both servos to operate as flaps. The amount of travel available as flaps is independently adjustable in FLAPERON. A trimming feature is also available (see FLAP-TRIM) to adjust both neutral positions together for straight-and-level flight or slight increases/decreases of the flap angle. END POINT and SUB-TRIM both still adjust each servo individually.

Adjustability:

•

Each aileron servo's up travel can be set separate from its down travel, creating aileron differential. (See example).

•

Each aileron servo's travel when actuated as a flap is separately adjustable.

•

AIL2 can be utilized to use a 5-channel receiver and still have flaperons. NOTE: The AIL2 function only commands the channel 5 servo to operate with the aileron servo as ailerons, and to obey the primary flap control (travel adjusted in

FLAP-TRIM.) It does not provide full flap mix capability as when using a 6+ channel receiver and channel 6.

NOTE: Activating flaperons only makes the ailerons work as ailerons and tells the radio how far you want them to move as flaps IF you then activate other programming that moves them as flaps.

FLAP-TRIM is the flap-trimming feature that allows the flaps to move in reaction to the channel 6 control. It is meant only for trimming the flaps' center but can also be used as full flap control. (See p. 46).

AIRBRAKE is a feature that drops flaperons as flaps, and also compensates with elevator if desired. (See p. 55).

FLAP-ELEVATOR would add elevator mixing into the flap movement from the flap dial after FLAP-TRIM is activated.

Using

FLAP-TRIM (camber) to adjust flaperons: (ACRO/GLID)

FLAP-TRIM assigns the primary flaperon control [defaults to VR(A)] to allow trimming in flight of the flap action of flaperons. (Note: even if FLAP-TRIM is made active with AIL-DIFF,

it will not have any effect. The ONLY function that allows control of the ailerons as flaps in the

AIL-DIFF configuration is AIRBRAKE.) Most modelers use AIRBRAKE, or programmable mixes, to move the flaps to a specified position via movement of a switch.

FLAP-TRIM may also be used as the primary flap control in flight. By doing so, you can assign CH6 to a 3-position switch, with a "spoileron", neutral, and "flaperon" position, and even adjust the percentage traveled as flaperon/spoileron by changing the Flap Trim travel. (Note that there is only one setting, not independent settings for up and down travel.)

Add

FLAP-TRIM to allow the model's ailerons to be trimmed together as flaps at any time during the flight, with a maximum travel of 5% of the total flap travel set in

FLAPERON.

AIRBRAKE/BUTTERFLY (crow) mixing (ACRO/GLID):

Like FLAPERON and AILEVATOR, AIRBRAKE is one function that is really made up of a series of pre-programmed mixes all done for you within the radio. AIRBRAKE (often called “crow” or BUTTERFLY - see GLID, p. 69 for details) simultaneously moves the flap(s) (if installed), twin ailerons (if installed) and elevator(s), and is usually used to make steep descents or to limit increases in airspeed in dives.

This function is often used even on models without flaps as an easy way to use the flaperons and FLAP-ELEVATOR mixing together.

Adjustability:

is lowered. If you would like to have the airbrake be directly proportional to throttle stick, you will need to reverse the

THR-REV function. Note that this changes the throttle stick direction for all mmodels. See page 31 for instructions.

• MANUAL (ACRO only): Provides AIRBRAKE response immediately upon switch movement, going to a pre-set travel on each active channel without any means of in-flight adjustment. ( MANUAL option not available in GLID modes.)

• Delayed reaction: You can suppress sudden changes in your model's attitude when AIRBRAKE is activated by setting the delay (

DELAY-ELE) item, to slow down the elevator response, allowing the flaps/ailerons/elevator to all reach their desired end point together. A setting of 100% slows the servo to take approximately one second to travel the prescribed distance.

• Adjustable in flight: Using the elevator trim lever in flight will adjust the elevator settings in your airbrake rather than adjusting the model's actual elevator trim. This allows easy adjustment for any ballooning while in flight. When the airbrake switch is moved to off the trims are again adjusting the normal elevator trim.

• Channels controlled: Elevator(s), twin ailerons and flap(s) may be set independently in AIRBRAKE, including set to 0 to have no effect.

• Twin aileron servos: If FLAPERON, ELEVON and AIL-DIFF functions are inhibited, then AIL1 and AIL2 settings will have no effect.

• If FLAPERON is active, the travel of the ailerons can be independently adjusted for the servos plugged into CH1 and CH6. The flap choice has no effect on the flaperons.

• If AIL-DIFF is active, then CH1 and CH7 may be independently adjusted.

• Normally both ailerons are raised equally in AIRBRAKE, and the elevator motion is set to maintain trim when the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other unique characteristics of the model.

Be sure you understand what dropping ailerons will do when in AIRBRAKE/BUTTERFLY. Along with creating an enormous amount of drag (desirable for spot landings), this also creates "wash-in", a higher angle of attack where the ailerons are, and encourages tip stalling. If you are using this for aerobatic performance and not "sudden stops", consider raising the ailerons and dropping the flaps instead as shown in the diagram above.

• Twin elevator servos:

• If AILEVATOR is active, the AIL1 and AIL2 settings still only affect FLAPERON or AIL-DIFF servos, NOT the elevator servos. (they would have the AIL3 and AIL4 settings.)
