WARNING

PROHIBITED ITEMS
Do not fly in the following places:
Do not fly simultaneously on the same frequency.
Interference may cause a crash.
Simultaneous flight on the same frequency prohibited
*Use of the same frequency will cause interference even if the modulation method (AM, FM, PCM) is different.
Do not fly on rainy or windy days, or at night.
Water will penetrate into the transmitter and cause faulty operation, or loss of control, and cause a crash.

Do not fly

Radiowave interference and obstructions may cause a crash. A crash caused by trouble in the R/C set, or the model itself, may cause death or property damage.
Do not fly when you are tired, sick, or intoxicated.
Fatigue, illness, or intoxication will cause a loss of concentration or normal judgment and result in operation errors and a crash.

MANDATORY ITEMS

Extend the antenna to its full length.
If the antenna is too short, the effective range of the radiowaves will become shorter.
Always test the digital proportional R/C set before use.
Any abnormality in the digital proportional R/C set, or model, may cause a crash. *Before starting the engine, check that the direction of operation of each servo matches the operation of its control stick. If a servo does not move in the proper direction, or operation is abnormal, do not fly the plane.

Extend to full length

CHECK ITEMS
Check that the transmitter antenna is not loose.
If the transmitter antenna comes off during use, control will be lost and the model will crash.
-Near other R/C flying fields (within about 3km) -Near people on the ground, or objects in the air -Near homes, schools, hospitals, or other places where there is a lot of people -Near high tension lines, high structures, or communication facilities

CAUTION

Do not touch the engine, motor, and FET amp during and immediately after use.
They are hot and will cause a burn.
When placing the transmitter on the ground during flight preparations, be sure that the wind cannot knock it over.
If it is knocked over, the throttle stick may be pushed to full high and the engine will race and create a dangerous situation.
When turning on the power switch

After setting the transmitter throttle stick to maximum slow, 1. Turn on the transmitter power switch, 2. Then turn on the receiver power switch.
When adjusting the digital proportional R/C set, always stop the engine, except when necessary.
If the engine suddenly goes to high speed, it may cause an injury.
When turning off the power switch
After stopping the engine, 1. Turn off the receiver power switch, 2. Then turn off the transmitter power switch. If the power switch is turned off in the opposite order, the engine may go to full throttle unexpectedly and cause an injury. *Maximum slow: Direction in which the engine or motor runs at the slowest speed.

Power ON

When flying, always install the frequency board to the transmitter antenna.
When the frequency was changed, also change the frequency board.

TRANSMITTER OPERATION AND MOVEMENT OF EACH SERVO
Before making any adjustments, learn the operation of the transmitter and the movement of each servo. (In the following descriptions, the transmitter is assumed to be in the standby state.)

AILERON OPERATION

When the aileron stick is moved to the right, the right aileron is raised and the left aileron is lowered, relative to the direction of flight, and the plane turns to the right. When the aileron stick is moved to the left, the ailerons move in the opposite direction. To level the plane, the aileron stick must be moved in the opposite direction. When the aileron stick is tilted and held, the plane will roll.

ELEVATOR OPERATION

2.Elevator
Down Down Down Up Up Up (Mode 1) (Mode 2)

3.Throttle

High High High
Engine throttle lever moves to the high speed side.
When the elevator stick is pulled back, the tail elevator is raised and the tail of the plane is forced down, the air flow applied to the wings is changed, the lifting force is increased, and the plane climbs (UP operation). When the elevator stick is pushed forward, the elevator is lowered, the tail of the plane is forced up, the air flow applied to the wings is changed, the lifting force is decreased, and the plane dives (DOWN operation).
Low Low Low (Mode 1) (Mode 2)
Engine throttle lever moves to the low speed side.

THROTTLE OPERATION

When the throttle stick is pulled back, the engine throttle lever arm moves to the SLOW (low speed) side. When the throttle stick is pushed forward, the throttle lever arm moves to the HIGH (high speed) side.

4.Rudder

Left Light

RUDDER OPERATION

When the rudder stick is moved to the right, the rudder moves to the right and the nose points to the right, relative to the direction of flight. When the rudder stick is moved to the left, the rudder moves to the left and the nose points to the left and the direction of travel of the plane changes.
INSTALLATION AND ADJUSTMENT
This section describes the installation method and adjustment method after installation when installing the receiver, servos, etc. to the plane.

CONNECTIONS

Connection examples are shown below. Make the connections matched to the type of set.

CONNECTION EXAMPLE

Receiver R127DF
*The number of servos depends on the set. Rudder (CH4) Throttle (CH3) Elevator (CH2) Aileron (CH1)

Receiver switch

Nicd battery

Receiver R115F

Receiver battery holder *Insert four batteries. *When using 5 or more servos, use the nicd battery sold separately.
CONNECTOR CONNECTION Insert the receiver, servo, and battery connectors fully and firmly.
If vibration, etc. causes a connector to work loose during flight, the plane may crash.
SERVO THROW Operate each servo horn over its full stroke and adjust so that the pushrod does not bind or is not too loose.
Unreasonable force applied to the servo horn will adversely affect the servo and drain the battery quickly.
RECEIVER VIBRATIONPROOFING / WATERPROOFING Vibrationproof the receiver by wrapping it in sponge rubber or some such material. If the receiver may get wet, waterproof it by placing it in a plastic bag.
If the receiver is subjected to strong vibration and shock, or gets wet, it may operate erroneously and cause a crash.
SERVO INSTALLATION Install the servos to the servo mount, etc. through a rubber bushing. Also install the servos so that the servo case does not directly touch the servo mount or other parts of the fuselage.

Wood screw

RECEIVER ANTENNA Do not cut or bundle the receiver antenna. Also, do not bundle the antenna together with the servo lead wires.
Cutting or bundling the receiver antenna will lower the receiver sensitivity and shorten the flight range and cause a crash.
Servo Rubber bushing Grommet Servo mount
<Antenna installation>
For aircraft, attach the antenna to the top of the tail.

Attach the antenna with a rubber band, etc.
POWER SWITCH INSTALLATION
When installing a receiver power switch to the fuselage, cut a rectangular hole somewhat larger than the full stroke of the switch knob and install the switch so it moves smoothly from ON to OFF. Also install the switch where it will not come into direct contact with engine oil, dust, etc. Generally, install the switch to the fuselage at the side opposite the muffler exhaust.
Use a rubber bushing, etc. at the part at which the antenna comes out of the fuselage so that it will not break. Also tie a knot in the antenna wire inside the fuselage so that the antenna cannot be pulled out.

ADJUSTMENTS

The operating direction, neutral position, and steering angle of each servo are adjusted.
The basic linkage and adjustments of the fuselage conform to the fuselage design drawings and kit instruction manual. Be sure that the center of gravity is at the prescribed position.

ADJUSTMENT PROCEDURE

Before making any adjustments, set all the SERVO REVERSER switches on the front of the transmitter to the lower (NOR) position. (Switch the switches with a small screwdriver, etc.) Turn on the transmitter and receiver power switches and make the following adjustments:
tion has changed, reset it by adjusting the length of the rod with the linkage rod adjuster. Perpendicular Rod
1 Check the direction of operation of each servo
If a servo operates in the wrong direction, switch its SERVO REVERSER switch. (The direction of operation can be changed without changing the linkage.) *Note that the direction of the aileron servo is easily mistaken. (Page 11)

SERVO REVERSER REV.

When the throw is unsuitable (different from steering angle specified by the kit instruction manual), adjust it by changing the servo horn and each control surface horn rod.
Check the engine throttle (speed adjustment) linkage.
Change the servo horn installation position and hole position so that the throttle is opened fully when the throttle stick is set to HIGH (forward) and is closed fully when the throttle stick and throttle trim are set for maximum slow (backward position and lower position, respectively).
2 Check the aileron, elevator,
and rudder neutral adjustment and left-right (up-down) throw.
Check that when trimmed to the center, the servo horn is perpendicular to the servo and check the neutral position of the fuselage control surfaces (aileron, elevator, rudder, etc.). If the neutral posi-

GLOSSARY

The following defines the symbols and terms used in this instruction manual. Aileron (AIL.)
Control surface at the left and right sides of the main wing of an aircraft. It usually controls turning of the aircraft.

Rudder (RUD.)

Tail control surface that controls the direction of the aircraft.

Reverse (REV.) Channel

Represents the number of control systems. It can also represent the number of servos that are operated. With the servo reversing function, this is used to mean the reverse side. The opposite side is the normal side.

Rod Down

Means down elevator. It is the direction in which the trailing edge of the elevator is pointing down. A bar that connects the servos and the fuselage control surfaces.

Servo horn

A part that is installed to the shaft of a servo and changes the rotating motion of the servo to linear motion and transmits the linear motion to a rod. Servo horns come in various shapes.

Elevator (ELE.)

Control surface that moves up and down on the horizontal stabilizer of an aircraft. It usually controls up and down.

Linkage

Mechanism that connects the servos and the fuselage control surfaces.

Servo mount

Fuselage base for installing a servo to the fuselage.

Modulation method

Two modulation methods are used with radio control: AM (Amplitude Modulation) and FM (Frequency Modulation). Radio sets for aircraft mainly use FM. Another method that encodes and transmits the modulated signals is called "PCM".
Rod for operating the transmitter.

Throttle (THR.)

Part that controls the air mixture at the engine intake. When opened (throttle high side), a large air mixture is sucked in and the engine speed increases. When closed (throttle low side), the engine speed decreases.

Neutral

Means the neutral position. It is the state in which a transmitter stick returns to the center when not operated.
A device that fine adjusts the neutral point of each servo for safe flying. It is a mechanism that corrects bad tendencies of the aircraft.

Normal (NOR.)

For the servo reversing function, it is the normal side. The opposite side is the reverse side.
Means up elevator. Direction in which the trailing edge of the elevator is pointing up.

Proportional

Because today's radio control sets control servos in proportion to stick operation, radio control equipment is called proportional.

DATA INPUT lever

Aileron and Elevator dual rate switch Use this switch to flip between two aileron and elevator control throw settings. The throws can be set up however you prefer, but generally, when the switch is up the throws are greater (high rate) and when the switch is down the throws are less (low rate). This switch also flips between exponential rates (if used). Flap control dial/Channel 6 This dial operates the servo connected to channel 6 in the receiver if your model has flaps this is the control used to operate them. Neck strap hook Mounting point for optional neck strap. Aileron/elevator control stick Operates the servos connected to channel 1 (aileron) and channel 2 (elevator) in the receiver. Trim levers (all) Used to shift the neutral or center position of each servo as labeled in the diagram. NOTE: The throttle trim lever is intended for fine tuning the throttle servo when the engine is at idle. Throttle trim does not affect the throttle servo when the throttle control stick is all the way up (so idle r.p.m. can be adjusted without affecting throttle settings through the rest of the stick movement). 4
Charging jack Port for charging the transmitter batteries with the included battery charger. On-off switch DATA INPUT lever Used to change the values of the various functions displayed on the LCD screen. Liquid-crystal display screen (LCD) Displays programming modes and values entered. MODE key Used to scroll through and display the seven different functions. SELECT key Used to display the values for the current function. Throttle/rudder control stick Operates the servos connected to channel 3 (throttle) and channel 4 (rudder) in the receiver. Trainer/throttle-cut switch Operates both the trainer and throttle-cut functions. To operate as a trainer switch the transmitter must be connected to another transmitter via. a trainer cord (available separately). To use the throttle-cut function, lower the throttle stick all the way, then rapidly depress the switch twice to fully close the carburetor and shut off the engine. Retractable landing gear switch/Channel 5 Switch operates the servo connected to channel 5 in the receiver if your model has retractable landing gear this is the control used to extend and retract the gear. Antenna Radiates signals to the receiver. Never fly a model without fully extending the antenna or you may create interference to other modelers and decrease operational signal range of the transmitter. The antenna may be removed and replaced with another in case it is inadvertently broken.

External antenna mounting: A. Use a cut off servo arm as a stop or strain relief inside the fuselage to keep tension off the solder joint holding the antenna to the receiver. Guide the antenna through a hole in the fuselage. (If possible, insulate the hole with a rubber grommet or a small piece of rubber tubing.)
B. Make a hook from another cut off servo arm. Insert the end of the antenna through two holes, then connect the hook to a rubber band around a pin inserted into the vertical stabilizer. Allow any excess antenna length to trail behind the hook.
The receiver contains precision electronic parts. It is the most delicate (and expensive) radio component on-board the model and should be protected from vibration, shock and temperature extremes. To protect the receiver, wrap it in R/C foam rubber or other vibration-absorbing material. If appropriate, waterproof the receiver by placing it in a plastic bag and closing the open end with a rubber band before wrapping it in foam. If moisture enters the receiver, intermittent operation or a failure may result. Wrapping the receiver in a plastic bag also protects it from fuel and exhaust residue which, in some models, can work its way into the fuselage.
Mounting the frequency clip: To announce your frequency and avoid potential interference problems, the frequency number should always be displayed on the transmitter antenna while flying. Peel the backing from the numbers and apply them to both sides of the clip. Snap the end of the clip that fits best to the base of the antenna as shown. You may cut off the other end of the clip. 6

To Battery

CHARGING THE Ni-Cd BATTERIES
The transmitter and receiver batteries included with your 6EXA system are rechargeable, Ni-Cd (nickel-cadmium, pronounced ni kad) batteries. Ni-Cd batteries require special care and charging. Read the charging instructions carefully. NOTE: The batteries are supplied partially charged but will require a full, overnight charge before the model may be flown. 1. Connect the transmitter charging cord coming from the A/C wall charger to the charge jack in the right side of the transmitter case. The receiver charging cord may be connected to the batteries two different ways: The charge cord may be connected directly to the battery pack, or to the vacant charge connector (black) coming from the on/off switch in the model. Charging through the switch is preferred as there will be no need to disconnect the battery. 2. Plug the A/C wall charger into a wall outlet. Note: If the wall outlet can be turned off by a switch in the room, be certain the switch remains on after leaving the room. Otherwise, the batteries will not be charged! 3. The LEDs (light-emitting diodes) should light red, indicating that current is flowing and the batteries are being charged. Discharged batteries will take about 15 hours to fully charge. If using an aftermarket fast charger, be certain to follow the manufacturers instructions provided with the charger so you do not overcharge the batteries. NEVER charge 7
the batteries at a rate higher than 1,000mAh. The batteries should also be discharged periodically to prevent a condition called memory. If, for example, only two flights are made each time you go flying, the batteries will not have reached very far down into their full capacity. After doing this several times the batteries will remember and eventually think they can supply only enough power for two flights. After two flights the batteries may not provide enough power to operate the system, thus causing a crash. To erase any potential memory, cycle the batteries by discharging, then charging them with a commercial battery cycler, or leave the system on and exercise the servos by moving the transmitter sticks until the servos are moving very slowly, indicating that the battery is discharged. Cycling should be done every one to two months, even during the winter or periods of long storage. If using a cycler with a readout, note the capacity after the batteries have been cycled. If there is a noticeable drop in capacity the batteries should be replaced. Note: Charging your batteries with the included Futaba A/C battery charger is always safe. However, fast-charging with an aftermarket charger is acceptable as long as you know how to properly operate the charger. NEVER charge at a rate higher than 1,000 mAh (1 Amp). If not done correctly, fast-charging can damage the batteries.

LIQUID CHIP DISPLAY (LCD) & PROGRAMMING CONTROLS
MODE key - use to select desired function while programming
To open programming menu; Press both keys simultaneously and hold for one second
SELECT key - use to select items within function to be set or changed in the screen LCD display screen
DATA INPUT lever - use this lever to input numbers or settings
Current model memory When the transmitter is initially turned on, the model memory number and transmitter battery voltage are displayed on the LCD screen. When prompted by the user, the functions and settings stored in the memory can also be read on the screen. The user accesses the different functions using the MODE and SELECT keys and changes the values and settings using the DATA INPUT lever. (This is called programming!) Transmitter battery voltage
Note: Feel free to explore by scrolling through the programs and viewing the displays using the MODE and SELECT keys. The MODE and SELECT keys only determine what will be displayed on the screen and will not change any of the settings. Only when using the DATA INPUT lever will you be able to change any of the settings. 8
Model memory number The Futaba T6EXA stores model memories for six models. This means all the data (control throws, trims, end points, etc.) for up to six different models can be stored in the transmitter and activated at any time (depending upon which model you choose to fly that day). This eliminates the requirement for reconfiguring the transmitter each time you decide to fly a different model with it! When the transmitter is turned on the model number and the transmitter voltage will be indicated on the LCD screen. Before every flight BE CERTAIN that the correct model number for the model you intend to fly appears on the screen. If the transmitter is not operating the correct model, some (or all) of the controls could be reversed and the travels and trims will be wrong. Flying a model with the wrong program will result in a crash, so always be certain the model number in the transmitter is correct. One way to ensure this is to write the corresponding model number directly on the airplane, or attach a list to the bottom or back of the transmitter.
Transmitter battery voltage In addition to the model number, the LCD screen also displays the transmitter battery voltage. When the voltage goes below approximately 8.5 Volts the battery icon will f l a s h and the low-battery alarm will continuously beep until the transmitter is turned off. When the low-battery alarm sounds you will have approximately four minutes (or less) to land your model before losing control. You should never allow the transmitter voltage to become this low while flying, but if it does, land immediately.

Note: When the transmitter voltage reads 8.9 Volts you will still have approximately ten minutes (or less) before losing operational range, so this is the recommended absolute minimum voltage. If the transmitter ever reaches 8.9 Volts, land as soon as safely possible. A more reasonable margin of safety would be to quit flying for the day (or recharge the batteries) when the transmitter battery is at 9.4 Volts.
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!
PROGRAMMING THE 6EXA RADIO
Anytime you wish to view or change any of the current settings in the transmitter, the programming mode must first be entered by, of course, turning on the power, then by pressing the MODE and SELECT keys simultaneously and holding them down for one second. Once in the program the MODE key will be used to scroll through each of the seven functions (model number, reversing, dual rates & exponentials, end point adjustments, trim, programmable mix and the preprogrammed wing mixing) and the SELECT key will be used to view the settings within the function. When a data change is actually required the DATA INPUT lever will be used to increase or decrease the value of the item displayed, thus making the change. You can return to the home screen (where the model number and battery voltage is displayed) by pressing the MODE and SELECT keys simultaneously and holding them down for one second. Note: The functions are listed and described in the order that they appear in the transmitter. Read all the way through the programming instructions before setting up your model (if you wont be using any of the mixing functions for a while you can read those instructions when ready). Refer to the FLOW CHART on page 16 as well. 9

Model Select/Data Reset

Model select function Access the Model Select function in the programming mode (by pressing the MODE and SELECT keys simultaneously and holding them down for one second). The number for the current, active model will be blinking. To activate a different model memory press the DATA INPUT lever until the desired model number appears. Now the model has been selected. All programming inputs from this point forward will affect only the model number on the screen (until another model number is selected).

Data reset function All the data for any model memory can be reset to the original, factory defaults. Often this function is done to get a fresh start and clear the memory before inputting new model settings. To reset data: 1. Access the Model Select function in the programming mode (by pressing the MODE and SELECT keys simultaneously and holding them down for one second). Use the DATA INPUT lever to select the model memory you wish to reset. 2. Once the desired model number is displayed on the screen, press the SELECT key. A CL will appear on the screen. 3. Press the DATA INPUT up or down for two seconds to clear and reset the memory. Now the data for this model has been reset to the original, factory defaults. CAUTION: Resetting the current model memory will permanently erase ALL programming information for that model. The data cannot be recovered (unless you recorded it on a Model Data Recording Sheet in the back of this manual). Do not reset the model unless certain you want to flush-out that memory and start from scratch. When actually setting up a model you should have the model in front of you with the power on so you can actually see the effects of your programming inputs and measure the control throws.

REVERSE

Servo Reversing
The servo reversing function is used to change the direction that a servo responds to a control input from the transmitter (stick, dial or switch). After using the reversing function, check all the controls on the model to be certain they are operating in the correct direction and that you did not inadvertently reverse a servo other than the one intended. Reversing the wrong servo (and not checking the response of the controls before each flight) may be the most common cause of a crash! To reverse a servo: 1. Enter the programming mode and use the MODE key to access the REVERSE function. 2. Use the SELECT key to select the channel you wish to reverse. The active channel number will be displayed in the upper, right corner of the screen. 3. Push the DATA INPUT lever down to reverse the servo (REV), or push the lever up to make the servo operate normally (NOR). The arrow will indicate the condition of the servo (normal or reversed). In the diagram channel 1 (aileron) is normal (not reversed). 4. Use the SELECT key to display other channels to be reversed. D/R Dual Rates/Exponential Settings The aileron and elevator dual rates on the 6EXA are simultaneously activated by the dual rate switch. The amount of travel decrease for each control may be set between 0% and 100% of the values set for the end points (explained in End Point Adjustment on page 11). Note: It is possible to set a dual rate value to zero, thus causing no response from that channel. If the dual rates are inadvertently set to zero, a crash could result.

Note: When performing initial model setup, the E.P.A.s should be set prior to setting the dual rates. When setting the E.P.A.s for the first time on a new model, the dual rates should be set to 100%. 10
Dual Rate Settings To set the dual rates: 1. Enter the programming mode. Access the D/R screen with the MODE key. 2. Select the channel to be adjusted (1-aileron, 2-elevator) by pressing the SELECT key until the desired channel number appears on the screen. Note: If a + or a appears next to the number, you have pressed the SELECT key too many times and displayed the values for the exponentials (explained later). Press the SELECT key to return to the dual rate values. 3. Place the dual rate switch in the desired position for the value you wish to change. (Generally, pilots prefer to have the switch in the up position for the high rate, and in the down position for the low rate.) 4. Change the dual rate value using the DATA INPUT lever until the desired control throw is achieved. If you wish to change the control throw when the switch is in the other position as well, flip the switch, then use the DATA INPUT lever to change the throw. 5. Repeat the procedure for the other dual rate (channel 2-elevator).
Exponential Settings The exponentials are in the same function as the dual rates. (Pressing the MODE key will take you to the next function which is End Point Adjustments). The same as dual rates, expos can be set for both switch positions. Negative exponential (-) decreases initial servo movement. Positive exponential (+) increases initial servo movement. The exponential curve may be set anywhere between -100% and +100%. To set the exponentials: 1. Enter the programming mode, then select the channel (1-aileron, 2-elevator) you wish to set by pressing the SELECT key. The active channel number will be displayed on the screen with a + or a - next to the number (initially, the value will read 0) 2. Position the dual rate switch where desired for the value you wish to change. 3. Enter the amount of exponential with the DATA INPUT lever. (As stated above, an exponential value with a - in front of it makes the initial servo movement less, or softer.) 4. Flip the switch to the other position to enter the exponential value for that switch position. 5. Repeat for the settings on the other channel.

End Point Adjustment

Note: Since changing the end points will also change the dual rates, the end points should be set prior to setting the dual rates. If you set the dual rates first, and then go back and change the end points, the dual rate throws will also change. The E.P.A. function is designed to fine tune the servo throws in cases where changing the pushrod hookup will not achieve the correct throw. The pushrods should first be connected to the servo arms and control horns so the correct, or near correct control surface throw will be achieved. THEN the E.P.A.s may be used to make small changes in the servo throw until the desired control throw is achieved. The control throws should be set up so that the end points are as near to 100% as possible. If the E.P.A. values must be set below 70% or above 120% to get the desired throw, you should strongly consider changing the pushrod connections so the values can be set closer to 100%. (When the E.P.A. is set to 100% the maximum servo throw for channels 1, 2, 3 & 4 is approximately 40 and approximately 55 for channels 5 & 6.)

1. Enter the programming mode and use the MODE key to activate the TRIM menu. 2. Press the SELECT key to display the channel to be adjusted (the figure shows trim adjustment for CH1). 3. Adjust the trim using the DATA INPUT lever. Note that initially, the values change in increments of 1, but if the DATA INPUT lever is held long enough the values will change more rapidly. 4. Repeat the steps for other channels that require trim adjustments.
P.MIX Programmable Mixer Unlike the wing mixing function (explained later) where the channels to be mixed are factory-set, the T6EXA also contains one programmable mix where the you, the pilot determine the channels to be mixed. This could be used to correct unwanted flight tendencies (by mixing rudder to aileron, or aileron to rudder for example).
To set up a programmable mix: 1. Until activated by the user, the P.MIX is inhibited (Inh). To activate the P.MIX enter the programming mode, then press the MODE key until P.MIX is displayed on the screen.
2. Push the DATA INPUT lever upward. This will cause the flashing Inh display to change to a flashing on display.
3. Select the channel that will control the mix (called the master) by pressing the SELECT key twice to display the channel number with the arrow above it, then by pressing the DATA INPUT lever to select the channel number desired. The channel on the screen with the arrow above it is now the master. In the diagram channel 1 (aileron) is the master.
4. Select the channel that will be mixed (called the slave) by pressing the SELECT key to get the arrow below the channel number displayed, then press the DATA INPUT lever to select the desired channel. The channel on the screen with the arrow below it is now the slave. In the diagram channel 4 (rudder) is the slave.
5. Press the SELECT key twice to display the flashing % sign. Use the DATA INPUT lever to set the percentage of mixing from -100% to +100% (depending on the direction and distance you wish the slave servo to move).
6. Observe how the controls on the model respond to be certain you have achieved the correct mix and that the throws are as desired.

To activate V-tail mixing: 1. Connect the left ruddervator servo to channel 2 (elevator) in the receiver and connect the right ruddervator servo to channel 4 (rudder) in the receiver.
3. Push the DATA INPUT lever until v is displayed on the screen. Now the mixing is on. The servo travels will be automatically reduced to 60%, but full servo throw will still be achieved when the elevator stick and rudder stick are moved to their extremes.
Flaperon + v-tail mixing (FPv)
This mixing function is used when both V-tail mixing and flaperon mixing are required. To activate Flaperon + V-tail mixing: 1. Connect the left ruddervator servo to channel 2 (elevator) in the receiver and connect the right ruddervator servo to channel 4 (rudder) in the receiver. 2. Connect the aileron servo in the right wing to channel 1 (aileron) in the receiver and connect the aileron servo in the left wing to channel 6 (flaps) in the receiver. 3. Enter the programming mode and access the W.MIX menu using the MODE key. 4. Push the DATA INPUT lever until FPv is displayed on the screen. Check all the control throws to make certain there is no binding at the extremes and that the throws are as desired. Adjust any linkages necessary to set the correct throws. Note: Reversing either of the servos involved with any of the mixing functions will reverse that servo, and that serv o o n l y not both servos involved in the mix. To reverse both servos, each must be reversed separately. This applies to programmable mixing and wing mixing.

OTHER 6EXA FUNCTIONS

Trainer switch To utilize the trainer function, the appropriate trainer cord (available separately) and a second Futaba transmitter (usually provided by your flight instructor or R/C club) will be required. When two radios are connected with the trainer cord, they are both capable of operating the model, but it s usually best for the instructor to hold the radio that has been setup for the plane to be flown (as it is already programmed to fly the model). When the instructor holds the trainer switch on his radio, the student will have control. When the instructor wishes to regain control he simply releases the switch. Then he will have immediate, full control. If connecting the 6EXA to another 6EXA with the small, square micro trainer jack, use the Micro to Micro (MM-TC) trainer cord (FUTM4415). If connecting the 6EXA to Futaba radios with the larger, round, DIN connector, use Micro to DIN (MD-TC) trainer cord (FUTM4420). The T6EXA transmitter may be connected to another T6EXA, or any 4VF, 6VA Skysport, FF6 - 9, or 9Z series transmitter. To use the trainer cord: 1. It is best for the instructor to use the transmitter that is already set up for the model to be flown. 2. If the students radio has PCM/PPM capability, set it to PPM. 3. If the students radio has a plug-in RF module, remove the module. 4. Collapse the student s antenna and fully extend the instructor s antenna.

Academy of Model Aeronautics 5151 East Memorial Drive Muncie, IN 47302-9252 Tele. (800) 435-9262 Fax (765) 741-0057 Or via the Internet at: http://www.modelaircraft.org IMPORTANT: If you do insist on flying on your own, you must be aware of your proximity to R/C club sites. If there is an R/C site within six miles of where you are flying, and if you are operating your model on the same frequency as somebody else, there is a strong possibility that one or both models will crash due to radio interference. There is great potential for an outof-control model to cause property damage and/or severe personal injury. We strongly urge you to fly at an R/C club site where frequency control is in effect so you can be confident you will be the only one flying on your channel. Charge the batteries Second to the pilots flight skills, one of the most important factors that can determine a models longevity is the state-ofcharge of the batteriesespecially the on-board receiver pack. Inadequate charging and failing to monitor a batterys voltage may lead to low battery power, causing loss of control and a crash. To avoid this, always charge the batteries the night before you go flying. If ever uncertain how much charge is left in a battery, it is wiser to err on the side of caution, rather than trying to get in one last flight! Due to the number of factors that determine receiver battery power consumption (such as the number and type of servos in your model, the type of flying you do, how much resistance is built into the controls, the size of the model, etc.), it is not possible to recommend how many flights one can get on a charge. The best way to monitor battery power and calculate how much flight time you have left is to use a volt meter to check the batteries after each flight. This can be done through the battery charging plug coming from the switch. There are many small, hand-held volt meters available specially intended for R/C use. The Hobbico Digital Voltmeter MKIII (HCAP0356) is one such unit. An on-board volt meter mounted directly on the model (HCAP0330) can also be used. 18

FLIGHT PREPARATION

Flight preparation is to be done at the flying field. IMPORTANT: Your radio control system transmits a signal on a certain frequency. Be certain you know what the frequency is. This is expressed as a two-digit number (42, 56, etc.), and can be found on the container the transmitter came in and is also located on the transmitter and receiver. There are several different frequencies, but there is still a chance that someone else at the flying field may be on the same frequency as you. Two models can never be operated at the same time on the same frequency no matter what the modulation (AM, FM, PCM). If you turn on your transmitter while another person is flying on the same frequency, a crash will result. NEVER turn on your transmitter until you have permission from your instructor, and until you have possession of the frequency clip used for frequency control at the flying site.

If you are an inexperienced pilot, be certain your flight instructor performs these following checks with you. Check the controls 1. Get the frequency clip from the frequency control board at your flying site. 2. Mount the wing to the fuselage. Turn on the transmitter, then the receiver (remember to do this in reverse order when turning off the system). Be certain the correct model memory matching the model you will be flying is the one on the LCD screen. 3. Operate and observe the controls. Look for inadvertent movement and listen for abnormal servo sounds. If problems are noted, correct them before flying. Look for binding pushrods or servo arms or pushrods that interfere with each other. 4. One at a time, operate each control on the airplane using the sticks on the transmitter to make certain each control is responding correctly. This must be done before every flight. (There are several types of malfunctions that can be discovered by performing this elementary task, thus saving your model!) Range check the radio A range check must be performed before the first flight of a new model. It is not necessary to do a range check before every flight (but is not a bad idea to perform a range check before the first flight of each day). A range check is the final opportunity to reveal any radio malfunctions, and to be certain the system has adequate operational range. 1. Turn on the transmitter, then the receiver. Leave the transmitter antenna all the way down. Walk away from the model while simultaneously operating the controls. Have an assistant stand by the model and signal what the controls are doing to confirm that they operate correctly. You should be able to walk approximately 20 - 30 paces from the model without losing control or seeing jitter in the servos. 2. If everything operates correctly, return to the model. Set the transmitter in a safe, yet accessible location so it will be within reach after starting the engine. Be certain the throttle stick is all the way down, then start the engine. Perform another range check with your assistant holding the plane and the engine running at various speeds. If the servos jitter or move inadvertently, there may be a problem. Do not fly the plane! Look for loose servo connections or binding pushrods. Also be certain you are the only one on your frequency, and that the battery has been fully charged. 4. When ready to fly, remember to fully extend the transmitter antenna. Avoid pointing the antenna directly at the model as the signal is weakest in that direction. Do not fly in the rain! 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 the transmitter with a plastic bag or other waterproof cover. MODEL DATA RECORDING SHEET After finalizing the programming for each model, fill out the values and settings in the Model Data Recording Sheets in the back of the manual. The data sheets will serve as a backup in case a program is ever lost or inadvertently reset, or in case you have to intentionally reset a program to make room for another model. Make additional copies before filling out the sheets.

Available separately, Futaba Flight Packs contain a receiver, servos, switch, battery and all servo mounting hardware. Consult your dealer or the Futaba Service Center for specific contents and order numbers. Receiver crystals: The receiver frequency may be changed as long as it remains within the low and high band frequency range. If your receiver is on any channel from 11 through 35, it is a low band receiver and the frequency may be changed to any other channel from 11 through 35 without having to perform any other service. Simply purchase a crystal on the desired channel, then replace the existing crystal in your receiver with the new one. If your receiver is on any channel from 36 through 60, it is a high band receiver and the frequency may be changed to any other channel from 36 through 60. To order a receiver crystal, replace the ** in the order numbers below with the required channel number. (To order a receiver crystal on channel 30, order FUTL5730.)
