Glossary

Understanding these terms will help in reading the manual:

• Reversing (servo reversing): Function to change the direction of servo response. If a control responds incorrectly, reversing can correct it.
• Throw: The distance a control surface moves, typically measured at the trailing edge. Can also refer to servo arm travel.
• Dual rate (D/R): Allows switching between two control throws (e.g., high rate for aggressive maneuvers, low rate for sensitive flying) in flight.
• End point adjustment (E.P.A.): Sets the maximum servo rotation in either direction, limiting travel regardless of dual rate settings.
• Exponential: Modifies servo response to stick input, making initial movement softer (negative exponential) or more sensitive (positive exponential).
• Mixing: Allows two or more servos to operate together electronically, either in unison or opposition, with independent end point settings.

Introduction to the 6EX-2.4GHz System

IMPORTANT: Always turn on the transmitter first, then the receiver. Turn off the receiver first, then the transmitter. This prevents damage to servos or control surfaces and avoids unexpected motor activation.

Transmitter

Radio Installation

Follow these guidelines for proper mounting of servos, receiver, and battery:

• Ensure alignment tabs and notches on connectors are correctly oriented before plugging them in. Never pull wires; pull connectors instead.
• Use servo extension wires if servo wires are too short.
• Mount servos with supplied rubber grommets, avoiding overtightening screws. Ensure no part of the servo casing contacts mounting rails or the structure to prevent vibration transfer and premature wear.
• Note the numbers on servo arms, which indicate degrees off from 90° for manufacturing deviations.
• To center servos: Turn on transmitter and receiver, center trims, and place servo arms perpendicular to pushrods.
• Check that pushrods and servo arms do not bind or contact each other during full travel. Ensure controls operate smoothly without buzzing sounds from servos, which indicate excessive resistance and battery drain.
• Use the receiver on/off switch mounting plate as a template for cutouts. Mount the switch on the side opposite the engine exhaust, protected from accidental activation. Ensure the switch moves freely.
• For helicopters, use the switch cover and securely tighten screws. Follow model-specific instructions if needed.
• Provide a margin for servo lead wires to prevent breakage from vibration and fasten them at suitable points. Periodically check wires during maintenance.

Receiver's Antenna Installation

IMPORTANT: 2.4GHz systems have different characteristics than 27MHz and 72MHz frequencies. Read this section carefully for safe flight.

• The R606FS has two antennas with a diversity function to decrease receiving errors.
• The shorter wavelength of 2.4GHz makes it susceptible to signal loss. The diversity antenna system helps avoid this.
• Antenna Placement for Best Results:
1. Keep both antennas as straight as possible to maintain effective range.
2. Place antennas at 90 degrees to each other, maximizing distance between them.
3. For models with large metal objects, place antennas on opposite sides of the model for optimal RF signal.
4. Keep antennas at least half an inch away from conductive materials (metal, carbon). Do not bend the coaxial part of the antenna sharply.
5. Keep antennas away from motors, ESCs, and other noise sources.
• For actual installation, wrap the receiver with sponge or floating material to protect it from vibration.
• The receiver contains precision electronic parts and is the most delicate component. Protect it from vibration, shock, and temperature extremes. Wrap it in foam rubber or other vibration-absorbing material. Waterproofing with a plastic bag and rubber band can protect against moisture, fuel, and exhaust residue.

Transmitter Antenna

• Adjust the transmitter antenna so it is not pointed directly at the model during flight to ensure a strong signal.
• Perpendicular alignment to the transmitter face generally provides the best RF condition. Adjust to your preferred holding position.
• Never grip the antenna during flight, as this degrades RF quality.

Range Check the Radio

A range check is mandatory before the first flight of a new model and recommended before the first flight of each day. It is the final opportunity to detect radio malfunctions and confirm adequate operational range.

1. Power Down Mode: Hold the MODE key and turn on the transmitter. This mode reduces RF power for the range test. The red LED blinks, and the green LED is solid. A beep sounds every 3 seconds.
2. Walk away from the model while operating controls. Have an assistant signal control responses. Aim for approximately 30-50 paces without losing control.
3. Return to the model. Set the transmitter in a safe, accessible location. Ensure the throttle stick is down, then start the engine. Perform another range check with the engine running. Check for servo jitter or inadvertent movement. If issues arise, check servo connections, pushrods, and battery charge. Do not fly if problems persist.
4. Power Down Mode lasts 60 seconds. To exit early, press the MODE key again.
5. Never start flying while Power Down Mode is active.

Link Procedure

Each transmitter has a unique ID code. The receiver must be linked to the transmitter's ID code for operation. Factory-linked T/R sets do not require this. For separately purchased receivers, linking is necessary.

1. Place the transmitter and receiver within one meter of each other.
2. Turn on the transmitter.
3. Check the transmitter's back LED: solid green indicates RF signal is being sent.
4. Turn on the receiver.
5. Press and hold the receiver's "ID SET" switch for over one second, then release. The receiver begins linking.
6. A solid green LED on the receiver indicates successful linking. Verify servos operate via the transmitter.

Receiver and Servo Connections

Connect servos to the receiver for the indicated functions:

Diagrams illustrate connections for aircraft and helicopter models. Note: NEVER use dry battery for R606FS.

Charging the NiCd Batteries

The included rechargeable NiCd batteries require special care and charging.

• Batteries are supplied partially charged; a full overnight charge is required before the first flight.
• Charging Procedure:
1. Connect the transmitter charging cord to the transmitter's charge jack. The receiver charging cord can connect directly to the battery pack or to the vacant charge connector from the on/off switch. Charging through the switch is preferred.
2. Plug the A/C wall charger into a wall outlet. Ensure the outlet switch remains on.
3. LEDs should light red, indicating charging. Discharged batteries take approximately 15 hours to fully charge.
• Aftermarket Fast Chargers: Follow manufacturer instructions. NEVER charge at a rate higher than 1,000mAh.
• Battery Memory: To prevent memory effect, discharge batteries periodically. Cycle batteries by discharging and charging, or by exercising servos until slow movement. Do this every one to two months. If capacity drops noticeably, replace batteries.
• Note: The included Futaba A/C charger is safe. Fast-charging with aftermarket chargers is acceptable if done correctly. NEVER charge above 1,000 mAh (1 Amp).

Liquid Chip Display (LCD) & Programming Controls

The LCD screen displays model type, memory name, modulation, and battery voltage upon startup. Programming allows access to stored functions and settings.

• MODE key: Selects desired function during programming.
• SELECT key: Selects items within a function for setting or changing.
• DATA INPUT lever: Inputs numbers or settings.
• Throttle-cut button: Shuts off the engine.

Note: Exploring displays using MODE and SELECT keys does not change settings. Only the DATA INPUT lever alters values.

Model name

The Futaba T6EX-2.4GHz stores memories for six models, eliminating the need for reconfiguring the transmitter for different models. Always verify the correct model name is displayed on the LCD before each flight to prevent crashes due to incorrect settings.

Caution: Flying with the wrong program can lead to a crash. Ensure the model name is correct by writing it on the model or attaching a list to the transmitter.

Transmitter battery voltage

The LCD displays transmitter battery voltage. A flashing "battery" icon and continuous beeping indicate low voltage (below approx. 8.5 Volts). Land immediately when the low-battery alarm sounds.

• Suggested Guidelines:
• 9.4 Volts: No more flying until recharge.
• 8.9 Volts: Land as soon as safely possible.
• 8.5 Volts: Emergency - Land immediately!

Mixer alert warning (HELI only)

If the transmitter is turned on with throttle hold or idle up active, a "MIX" warning will sound. Turn off these functions to proceed.

Backup error

A "Backup error" warning indicates lost transmitter memory. All data will reset upon power-up. Initialization proceeds from model number 6 to 1. Do not turn off power during initialization, or it will restart.

Do not fly if this message is displayed, as programming is erased. Return the transmitter for service.

5. With transmitters off, connect the trainer cord. The plug is keyed.
6. Turn on instructor's transmitter. Student's transmitter powers up automatically. Set reversing and trims to match instructor's.
7. Turn on receiver. Depress trainer switch on instructor's radio. Use student's radio to operate controls and make adjustments.
8. Check trim sync by toggling the trainer switch. Controls should remain stationary. Adjust student's trims if necessary.

Note: A one-second delay occurs when the instructor first depresses the trainer switch. Trainer switch does not function in heli mode.

Trainer function (HELI mode, student only)

Allows practicing as a student by connecting the T6EX-2.4GHz to an instructor's Futaba transmitter.

Throttle-cut function

Shuts off the engine via the "THR Cut" button. Prevents accidental shutoff when lowering the throttle stick. Works only when the throttle stick is down.

To set up throttle-cut:

1. Turn on transmitter and receiver. Actuate throttle-cut function rapidly twice.
2. Observe carburetor barrel momentarily. It should be fully closed.
3. If necessary, use throttle EPA (CH3) to fully close the barrel.
4. Use throttle trim to open the carburetor barrel for desired idle RPM when the throttle stick is down.

Adjustable-length control sticks

Control stick length is adjustable for comfort. Hold the locking piece (B) and turn the stick tip (A) counterclockwise. Adjust locking piece B to lengthen or shorten the stick. Lock by turning piece B counterclockwise.

Changing the 6EX-2.4GHz stick mode

The transmitter supports four stick modes (1, 2, 3, 4). Mode 2 is the default and recommended for most users. Changing modes may require adjusting the throttle detent mechanism by the Futaba Service Center.

To change the mode: Simultaneously depress MODE and SELECT keys, then turn on power. The current mode appears on the LCD. Use DATA INPUT lever to change mode. Adjustments to throttle detent may be needed if throttle moves to the right stick.

Flying Safety Guidelines

Find a suitable flying site (for USA)

Joining an R/C club and flying at designated sites is highly recommended. AMA membership is required for AMA clubs. AMA provides insurance and training resources.

Flying on your own

Be aware of R/C club sites within six miles. Flying on the same frequency as another model can cause interference and crashes. Out-of-control models can cause damage or injury. Fly at R/C club sites with frequency control for safety.

Charge the batteries

Proper battery charging and voltage monitoring are crucial for model longevity and safety. Charge batteries the night before flying. Use a volt meter to check battery voltage after each flight. Hand-held or on-board volt meters are available.

Flight Preparation

Perform these checks at the flying field, ideally with a flight instructor:

Check the controls

1. Obtain a frequency clip if available at the flying site.
2. Mount the wing. Turn on the transmitter, then the receiver. Ensure the correct model memory is selected.
3. Operate controls, listening for abnormal servo sounds and checking for binding pushrods or servo arms. Correct any issues.
4. Operate each control individually using the transmitter sticks to confirm correct response. This is essential before every flight.

Range check the radio

Perform a range check before the first flight of a new model and recommended before each day's first flight.

1. Activate "Power Down Mode" by holding MODE and turning on the transmitter. Red LED blinks, green LED is solid. A beep sounds every 3 seconds.
2. Walk away from the model while operating controls. Have an assistant signal responses. Aim for 30-50 paces without losing control.
3. Return to the model. Set the transmitter in a safe location. Start the engine with the throttle stick down. Perform another range check with the engine running. Check for servo jitter or movement. Address any problems. Ensure the battery is fully charged.
4. Power Down Mode lasts 60 seconds. Press MODE to exit early.
5. Never start flying during Power Down Mode.

Do not fly in the rain! Moisture can cause erratic operation or loss of control. Cover the transmitter with a plastic bag if flying in wet weather.

Model Data Recording Sheet

Fill out the Model Data Recording Sheets (located in the back of the manual) after programming each model. These sheets serve as a backup in case of program loss or reset. Make additional copies before use.

MODEL DATA RECORDING SHEET (ACRO)

A template for recording ACRO model settings, including Servo Reverse, Dual Rate, EPA, Trims, Expo, Failsafe, Mixing settings (PMX1/2, Flaperon, V-Tail, Elevon), Flap Trim, and Trainer settings.

MODEL DATA RECORDING SHEET (HELI)

A template for recording HELI model settings, including Servo Reverse, Dual Rate, EPA, Trims, Expo, Failsafe, Mixing settings (N-TH, N-PI, I-TH, I-PI, HOLD, REVO, GYRO, SW-T, SWSH), and Swashplate Types.
