CAUTION - Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or physical damage, if not carried out properly.

= Prohibited

= Mandatory

Warning: Always keep electrical components away from small children.

FLYING SAFETY

To ensure the safety of yourself and others, please observe the following precautions:

Have regular maintenance performed. Although your 7C protects the model memories with non-volatile EEPROM memory (which does not require periodic replacement) and not a battery, it still should have regular checkups for wear and tear. We recommend sending your system to the Futaba Service Center annually during your non-flying-season for a complete checkup and service.

Ni-Cd Battery

Charge the batteries! (See Charging the Ni-Cd batteries, p. 14, for details.) Always recharge the transmitter and receiver batteries for at least 15 hours before each flying session. A low battery will soon die, causing loss of control and a crash. When you begin your flying session, reset your 7C's built-in timer, and during the session pay attention to the duration of usage.

Stop flying long before your batteries become low on charge. Do not rely on your radioís low battery warning systems, intended only as a precaution, to tell you when to recharge. Always check your transmitter and receiver batteries prior to each flight.

Where to Fly

We recommend that you fly at a recognized model airplane flying field. You can find model clubs and fields by asking your nearest hobby dealer, or in the US by contacting the Academy of Model Aeronautics.

You can also contact the national Academy of Model Aeronautics (AMA), which has more than 2,500 chartered clubs across the country. Through any one of them, instructor training programs and insured newcomer training are available. Contact the AMA at the address or toll-free phone number below.

Always pay particular attention to the flying field's rules, as well as the presence and location of spectators, the wind direction, and any obstacles on the field. Be very careful flying in areas near power lines, tall buildings, or communication facilities as there may be radio interference in their vicinity.

If you must fly away from a club field, be sure there are no other modelers flying within a three-to-five-mile range, or you may lose control of your aircraft or cause someone else to lose control.

At the flying field

Before flying, be sure that the frequency you intend to fly with is not in use, and secure any frequency control device (pin, tag, etc.) for that frequency before turning on your transmitter. It is never possible to fly two or more models on the same frequency at the same time. Even though there are different types of modulation (AM, FM, PCM), only one model may be flown on a single frequency at any one time.

To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:

1.Pull throttle stick to idle position, or otherwise disarm your motor/engine.

2.Turn on the transmitter power and allow your transmitter to reach its home screen.

3.Confirm the proper model memory has been selected.

4.Fully extend the transmitter antenna.

5.Turn on your receiver power.

6.Test all controls. If a servo operates abnormally, donít attempt to fly until you determine the cause of the problem.

(For PCM systems only: Test to ensure that the FailSafe settings are correct by waiting at least 2 minutes after adjusting and then turning the transmitter off and confirming the proper surface/throttle movements. Turn the transmitter back on.)

7.Start your engine.

8.Complete a full range check (see p. 17).

9.After flying, bring your throttle stick to idle position, engage any kill switches or otherwise disarm your motor/engine.

10.Turn off receiver power.

11.Turn off transmitter power.

If you do not turn on your system in this order, you may damage your servos or control surfaces, flood your engine, or in the case of electric-powered or gasoline-powered models, the engine may unexpectedly turn on and cause a severe injury.

While you are getting ready to fly, if you place your transmitter on the ground, be sure that the wind won't tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the engine to speed up. Also, damage to your transmitter may occur.

Before taxiing, be sure to extend the transmitter antenna to its full length.

A collapsed antenna will reduce your flying range and cause a loss of control. It is a good idea to avoid pointing the transmitter antenna directly at the model, since the signal is weakest in that direction.

Don't fly in the rain! Water or moisture may enter the transmitter through the antenna or stick openings and cause erratic operation or loss of control. If you must fly in wet weather during a contest, be sure to cover your transmitter with a plastic bag or waterproof barrier. Never fly if lightning is expected.

A QUICK INTRODUCTION TO THE 7C SYSTEM

Note that in the text of this manual, beginning at this point, any time we are using a featureís specialized name or abbreviation as seen on the screen of the 7C, that name, feature, or abbreviation will be exactly as seen on the radioís screen, including capitalization, and shown in a DIFFERENT TYPESTYLE for clarity. Any time we mention a specific control on the radio itself, such as moving SWITCH A, KNOB VR, or the THROTTLE STICK, those words will be displayed as they are here.

TRANSMITTER:

•Large graphic liquid-crystal display panel with 4 buttons and an easy set up turn-and-press Dial for quick, easy setup.

•All transmitters include all 2 aircraft types with specialized programming for each, including:

•Airplane (ACRO)

•V-TAIL • Twin Aileron Servos (FLAPRN )

•ELEVON • Snap Roll

•Air Brake

• Helicopter (6 swashplate types, including CCPM, see page 61)
•	2 Idle Ups	•	Throttle and Pitch Curves per Condition
•	Revo. Mixing	•	Gyro Mixing including Separate Settings per Condition

•BASIC menu for quick, easy set up of less complex models.

•ADVANCE menu for more complex, unique setups.

•Four electronic TRIM LEVERS for rapid yet precise trim adjustment - no remembering to "store trims" between models and no more "bumped trims" during transport.

•TH-CUT (ACRO/HELI) (engine shut off) setups to allow precise engine control for taxi and landings.

•10 complete model memories

•New stick design with improved feel, adjustable length and tension.

•Triple rates available by setting dual rates to 3-position switches.

•Six SWITCHES and 1D IAL ; assignable in some applications.

•Trainer system includes the "functional" (F ) setting, which allows the student to use the 7C'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.

•7CA 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.

•7CH transmitter features helicopter-friendly switch layout, with idle-up switch at the left hand, and a smooth, ratchet-less (unsprung) throttle for perfect hovering. Defaults to H-1 MODEL TYPE.

•In North America it is against FCC regulation to change the crystal within the transmitter 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.

7

RECEIVER: R127DF/R138DP

•The R127DF FM 7-channel or the R138DP PCM 7-channel receiver included with your system is a high-sensitivity narrow-band dual-conversion receiver.

•Any Futaba narrow band FM receiver (all produced after 1991) on the correct frequency band and frequency may be used with the 7C.

•Any Futaba PCM 1024 receiver on the right frequency band and frequency may be used with the 7C (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 (I.E. 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:

•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 7C transmitter may be connected to another 7C system, as well as to many other models of Futaba transmitters. The 7C 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 T7C 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 5- cell battery pack of the same mAh rating will last approximately æ 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. 56 for aircraft or p. 72 for helicopter gyro information.

•Basic control assignments of channels 5 & 7 are quickly adjustable in PARA (see p. 28). For example, the channel 5 servo, which defaults to SWITCH 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 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 Systemís 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

TX: Transmitter charging indicator RX: Receiver charging indicator

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.

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 your 7C transmitter system is protected from accidental reverse polarity, power surges and other electrical damage by a diode. The transmitter battery must be removed from the system to cycle. The battery easily unplugs from the battery compartment and has a standard J-plug for easy cycling.

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

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, youíll 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 from the transmitter.

Next, using a screwdriver, remove the four screws

that hold the transmitterís rear cover in position, and put them in a safe place. Gently ease off the transmitterís 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.

When the cover is properly in place, reinstall and tighten the four screws. Reinstall the battery cover.

Adjusting Display Contrast

To adjust the display contrast, from the home menu press and hold the End button. Turn the dial while still holding End button:

clockwise to brighten counterclockwise to darken the display

Let go off the dial and the button.

Changing Modes:

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

15

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 canít 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.

16

Range Testing Your R/C System

Please note that different systems demonstrate different range checks and the same system will range check differently in different conditions. Also, the receiver antenna's installation affects the range test -- exiting the top of the model is ideal.

This is a brief explanation of range test. For more in-depth specifics on receiver antenna mounting, additional checks if unsatisfactory range is demonstrated, range checking with gasoline powered engines, etc, please see our F.A.Q. page at www.futaba-rc.com.

•Leave the transmitter's antenna retracted and be sure both batteries are fully charged.

•Position the aircraft away from wires, other transmitters, etc.

Test one - engine/motor off, minimum of 100 ft. range

•Have a friend view the model but not hold it, engine off. (People conduct signals, too!)

•Walk away from the model, working all controls constantly. Stop when the servos jitter significantly (a jitter here and there is normal), control movement stops (PCM), or you lose control altogether.

•Measure the distance. If greater than 100 feet, great! Proceed to Test 2. Less than 100 feet of range check means you need more information to determine if your system is safe to fly. Please see our web site or call support for additional tests to perform before flying your system.

•Repeat with friend holding the model. Note any differences.

Test two - engine/motor on

•Repeat the test with the model's engine running and with someone holding the model. If a decrease of more than 10% is noted, research and resolve the cause of interference prior to flying your model.

What your fully operational system demonstrates is the normal range for your system in those conditions. Before every flying session, it is critical that you perform a range check. It is also required by the AMA Safety Code. If you notice a significant decrease in range with fully charged batteries, do not attempt to fly.

The following frequencies and channel numbers may be used for flying aircraft in the United States:

WARNING & ERROR DISPLAYS

An alarm or error indication may appear on the display of your transmitter for several reasons, including when the transmitter power switch is turned on, when the battery voltage is low, and several others. Each display has a unique sound associated with it, as described below.

LOW BATTERY ERROR: Warning sound: Continuous beep until transmitter is powered off.

The LOW BATTERY warning is displayed when the transmitter battery voltage drops below 8.5V.

Land your model as soon as possible before loss of control due to a dead battery.

flash

MIXER ALERT WARNING: Warning sound: 5 Beeps (repeated until problem resolved or overridden)

flash

The MIXER ALERT warning is displayed to alert you whenever you turn on the transmitter with any of the mixing switches active. This warning will disappear when the offending switch or control is deactivated. Switches for which warnings will be issued at power-up are listed below:

ACRO: Throttle cut, snap roll, airbrake HELI: Throttle hold, idle-up

If turning a switch OFF does not stop the mixing warning: When the warning does not stop even when the mixing switch indicated by the warning display on the screen is turned off, the functions described previously probably use the same switch and the OFF direction setting is reversed. In short, one of the mixings described above is not in the OFF state. In this case, reset the warning display by pressing both SELECT BUTTONS simultaneously. Then change one of the switch settings of the mixings duplicated at one switch.

BACKUP ERROR: Warning sound: 4 beeps (repeated continuously)

The BACKUP ERROR warning occurs when the transmitter memory is lost for any reason. If this occurs, all of the data will be reset when the power is turned on again.

flash

Do not fly when this message is displayed - all programming has been erased and is not available. Return your transmitter to Futaba for service.

A QUICK GUIDE: GETTING STARTED WITH A BASIC 4-CHANNEL AIRCRAFT

This guide is intended to help you get acquainted with the radio, to give you a jump start on using your new radio, and to give you some ideas and direction in how to do even more than you may have already considered. It follows our basic format of all programming pages: a big picture overview of what we accomplish; a "by name" description of what we're doing to help acquaint you with the radio; then a step-by-step instruction to leave out the mystery when setting up your model.

For additional details on each function, see that function's section in this manual. The page numbers are indicated in the goals column as a convenience to you.

See p.21 for a legend of symbols used.

A LOOK AT THE RADIO'S FUNCTIONS STEP BY STEP

MODELsubmenu: includes three functions that manage model memory: MODEL SELECT, MODEL COPY and MODEL NAME. Since these functions are all related, and are all basic features used with most models, they are together in the MODEL submenu of the BASIC menu.

MODEL SELECT: This function selects which of the 10 model memories in the transmitter to set up or fly.

(Each model memory may be of a different model type from the other memories.)

NOTE: When you choose a new model in the MODEL SELECT function, if the new model is set to the other modulation, you must cycle the transmitter power to change modulations. If you do not cycle the power, the modulation type will flash on the home screen to remind you. You are still transmitting on the other modulation until you affect this change.
