INTRODUCTION

Thank you for purchasing the Futaba®6EXAP digital proportional R/C aircraft system. If this is your first “computer”radio, rest

assured that it is designed to make initial setup and field-tuning of your airplane easier and more accurate than would be if

using a “non-computer”radio. Although this is a beginner or sport system with the requirements of those flyers in mind, in

order to make the best use of your Futaba 6EXAP and to operate it safely, you must carefully read all of the instructions.

Suggestion:

If, while reading the instructions, you are unclear of some of the procedures or functions and become “stuck,”

continue to read on anyway. Often, the function or procedure will be explained again later in a different way providing another

perspective from which to understand it. Another suggestion is to connect the battery, switch and servos to the receiver and

actually operate the radio on your workbench as you make programming changes. Then, you’ll be able to see the effects of

your programming inputs.

GLOSSARY

It will be helpful to understand the following terms before reading the rest of the manual. The terms are not in alphabetical

order, but are in a logical order that prepares the reader for understanding the next term.

Reversing (servo reversing) -

A function that allows the user to determine the direction of response of each servo. If, after

hooking up the servos, a control on the model responds in the wrong direction, the user may change the servo's direction so

the control responds correctly.

Throw -

When speaking of a control surface (such as an elevator or aileron), the throw is

the distance the surface moves. Control surface throw is usually measured at the trailing

edge of the surface and is expressed in inches or millimeters. The model in the diagram has

1/2" [13mm] of up elevator throw. Throw can also refer to the distance a servo arm (or

wheel) travels.

Dual rate (D/R) -

On the 6EXAP the dual rate switch allows you to instantly switch, in flight,

between two different control throws for the aileron, elevator and rudder. Often, different

control throws are required for different types of flying. (“Low”throws may be required for

flying at high speeds where the model’s response becomes more sensitive, and “high”

throws may be required for aggressive aerobatic maneuvers or landing or flying at lower

speeds where the model's response becomes less sensitive.)

End point adjustment (E.P.A.) -

Sets the overall, maximum distance the servo rotates in either direction. (No matter where

the dual rates are set, the servo will never travel beyond the limit set by the end point adjustment.)

Exponential -

Normally, servos respond proportionally to control stick input from the transmitter (e.g., if the stick is moved

halfway, the servo will move halfway). However, with “exponential,”the servo can be made to move more or less than initial

stick movement (less servo movement is more common). Exponentials are commonly used to “soften,”or decrease initial

servo travel for the ailerons, elevators and rudder. This way, initial control stick inputs from the pilot result in small servo

movement for a smoother flying airplane.

(Dual rates adjust the amount

amount

of servo travel. Exponentials determine where

where

most of the travel will occur.)

Mixing -

Two (or more) servos can be made to operate together either by mechanically joining the wires (with a Y-connector)

or by electronically “joining”them through programming functions in the transmitter. When servos are electronically joined via

programming, they are said to be “mixed.”Unlike joining servos with a Y-connector, when servos are mixed electronically they

can be made to move in opposition. Additionally, each servo’s end points can be independently set.

INTRODUCTION TO THE 6EXAP SYSTEM

IMPORTANT!:

Always turn on the transmitter first, then the receiver. When turning off the system, always turn off the receiver

first. The object is never to have the receiver on by itself. Otherwise, the servos or control surfaces could be damaged, or in

the case of electric-powered models, the motor may unexpectedly turn on causing severe injury.

IMPORTANT!:

Never collapse the transmitter antenna by pushing down from the top. If one of the segments becomes momentarily

stuck you may damage the antenna. Instead, collapse the antenna from the bottom, drawing in one segment at a time.

Transmitter

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

liquid-crystal display (LCD) on the face of the compact, ergonomically-designed case is easy to read and allows rapid data input.

The system also holds independent memories for six different models. The new, adjustable-length control sticks provide an

improved feel. External switches operate dual rates (D/R), landing gear, and trainer cord or “buddy-box”capabilities. Programming

features include servo reversing and E.P.A on all channels, dual rates, exponentials and programmable mixing. Additionally, any

one of four, factory-set, preprogrammed “wing-type”mixers including flaperon, V-tail, elevon mixing may be selected.

Transmitter controls

The diagram and explanations briefly describe the functions of the Futaba T6EXAP transmitter. Full instructions on how to

operate the controls are provided beginning on page 9.

NOTE:

The diagram shows a Mode 2 system as supplied. (More on flight modes on page 21).

DESCRIPTIONS:

Aileron, Elevator and Rudder dual rate switch

Use this switch to “flip”between two aileron, elevator and rudder 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).

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 ten or eleven(PCM) different functions.

SELECT key -

Used to display the values for the current function.

Throttle-cut button -

To use the throttle-cut function, lower the throttle stick all the way, then Push the throttle-cut button to

fully close the carburetor and shut of the engine.

Throttle/rudder control stick -

Operates the servos connected to channel 3 (throttle) and channel 4 (rudder) in the receiver.

Trainer switch -

Operates the trainer functions. To operate as a trainer switch the transmitter must be connected to another

transmitter via. a trainer cord (available separately).

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.

RADIO INSTALLATION

Follow these guidelines to properly mount the servos, receiver and battery.

•Make certain the alignment tab

alignment tab

on the battery, switch and servo connectors is oriented correctly and “keys”into the

corresponding notch in the receiver or connectors before plugging them in. When unplugging connectors, never pull on the

wires. Always pull on the plastic connector instead.

•If any servo wires are not long enough to reach the receiver, servo extension wires (available separately) may be used.

•Always mount the servos with the supplied rubber grommets

rubber grommets

. Do not over tighten the

screws. No part of the servo casing should contact the mounting rails, servo tray or any

other part of the airplane structure. Otherwise, vibration will be transmitted to the servo

causing premature wear and/or servo failure.

•Note the small numbers (1, 2, 3, 4) molded into each arm on the Futaba 4-arm servo arms.

The numbers indicate how many degrees each arm is “off”from 90 degrees to correct for

minute manufacturing deviations from servo to servo.

•To center the servos, connect them to the receiver and turn on

the transmitter and receiver. Center the trims on the

transmitter, then find the arm that will be perpendicular to the

pushrod when placed on the servo.

• After the servos are installed, operate each servo over its full travel and check that the pushrods and servo arms do not bind or

contact each other. Also make sure the controls do not require excess force to operate. If there is an objectionable buzzing

sound coming from a servo, there is probably too much resistance in the control. Find and correct the problem. Even if there is

no servo damage, excess battery drain will result.

• Use the mounting plate

mounting plate

from the receiver on/off switch as a template for the cutout and screw holes. Mount the switch on the

side of the fuselage opposite the engine exhaust, and where it won’t be inadvertently turned on or off during handling or

storage. Be certain the switch moves without restriction and “snaps”from ON to OFF, and that the cutout allows full motion

full motion

the switch in both

both

directions.

• IMPORTANT: NEVER

IMPORTANT: NEVER

cut the receiver antenna or mount it in the model folded back on itself. Doing so will change its

electrical length, possibly reducing the distance from the pilot that the model can be controlled (“range”).

• The receiver antenna may be mounted inside or outside the model:

Internal antenna mounting:

The antenna may be routed down through the inside of the fuselage, or through any non-metallic

non-metallic

housing or tube within the

fuselage. Keep the antenna away from metal pushrods, wires and cables; otherwise, range may be decreased. Always perform a

range check before flying (see page 22).

External antenna mounting:

A. Use a cut off servo arm as a “stop

stop

”or strain relief

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

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:

(for USA)

• 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.

CHARGING THE Ni-Cd BATTERIES

The transmitter and receiver batteries included with your 6EXAP system are rechargeable, Ni-Cd (nickel-cadmium, pronounced

ni-kad) batteries. Ni-Cd batteries require special care and charging. Read the charging instructionscarefully.

Read the charging instructionscarefully.

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

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

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:

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

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.

Note:

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.

Model memory number and model name

The Futaba T6EXAP 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

model number

, model

name

, modulation and the transmitter voltage will

be indicated on the LCD screen. Before every flight BE CERTAIN

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

be certain

the model number and model name 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

transmitter battery

voltage

. When the voltage goes below approximately 8.5 Volts

8.5 Volts

the “battery”icon will flash 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

immediately

PROGRAMMING THE 6EXAP RADIO

Anytime you wish to view

view

or change

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

MODE

”and “SELECT

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 ten or eleven(PCM) functions

(model number/ data reset/ modulation select/ model name, reversing, dual rates/ exponentials, end point adjustments, trim,

programmable mix, “flaperon”mixing, “v-tail”mixing, “elevon”mixing, flap trim and failsafe) and the SELECT key will be used to

view the settings within the function. When a data change is actually required the “DATA INPUT

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 won’t be using any of the mixing functions for a while you can

read those instructions when ready). Refer to the FLOW CHART on page 19 as well.

Note:

When the transmitter voltage reads 8.9 Volts

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.

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!

Model Select/Data Reset / Modulation Select/Model Name

MODL Model select function

To select model memory:

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). The number for the

current, active model will be blinking.

2. To activate a different model memory press the DATA INPUT lever until the desired model

number appears.

3. 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).

RCST 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 “REST

REST

”

will appear on the screen.

3. Push DATA INPUT upward or downward for about 2 seconds to clear and reset the memory.

“CLR”blinks first, and then it stops blinking with a sound. Now the model data is reset to the

initial setting that is the default value set at the factory.

The existing modulation setting is not reset. If the power switch is turned off while reset is underway, the data may not be

reset.

CAUTION:

Resetting the current model memory will permanently erase ALL

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 certainly

certainly

you want flushing-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.

PULS Modulation select function

The Modulation select function is used to select the PPM

PPM

or PCM

PCM

mode of transmission, to

match the receiver being used (PPM-Pulse Position Modulation, also called FM for Frequency

Modulation, and PCM-Pulse Code Modulation).

To select modulation:

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 modulation select.

2. Push SELECT key twice after seeing on the screen the model memory where you want to set

modulation, then you will see “PULS”on the screen.

3. To select PCM modulation, push the DATA INPUT lever up. The “PCM

PCM

”is displayed. To select

PPM modulation, push the DATA INPUT lever down. The “PPM

PPM

”is displayed.

4. To get the transmitter to operate in the new mode, switch transmitter power off and then on.

The small indicator will indicate the mode, either PPM or PCM.

Model name function

Assign a name to the model memory. By giving each model a name that is immediately recognizable, you can quickly select the

correct model, and minimize the chance of flying wrong model memory that could lead crash.

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 number you wish to change.

2.Once the desired model number is displayed on the screen, press the SELECT key. A NAME

will appear on the screen.

3. Choose a character for the first digit by using DATA INPUT lever. Then move to the next digit

by pressing the SELECT key and choose a character in the same way. Continue choosing

characters for the third and fourth digits. You can use up to four characters for the name.

REVR 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

all

the controls on the model to be certain

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 REVR

REVR

function.

2. Use the SELECT key to select the channel you wish to reverse.

3. Push the DATA INPUT lever downward to reverse the servo (REV), or push the lever upward

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.

The aileron, elevator and rudder dual rates on the 6EXAP 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 12).

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

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%.

D/R Dual Rate Settings

To set the dual rates:

1. Enter the programming mode. Access the “D/R

D/R

“screen with the MODE key.

2. Select the channel to be adjusted (1-aileron, 2-elevator, 4-rudder) by pressing the SELECT

key until the desired channel number the left side on the screen. Note: If a “EXPO

EXPO

“will

appear on the screen, 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, 4-rudder).

EXPO 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. Access the “D/R

D/R

“screen with the MODE key.

2. Access the “EXPO

EXPO

“screen with the SELECT key.

3. Select the channel (1-aileron, 2-elevator, 4-rudder) you wish to set by pressing the SELECT

key. The active channel number will be displayed on the screen Note: If a “D/R“ will appear

on the screen, you have pressed the SELECT key too many times and displayed the values

for the D/R (dual rate values). Press the SELECT key to return to the exponentials.

4. Position the dual rate switch where desired for the value you wish to change.

5. 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.”)

6. Flip the switch to the other position to enter the exponential value for that switch position.

7. Repeat for the settings on the other channel.

EPA 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 EPA 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 EPAs 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 EPA 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 EPA is set to 100% the maximum servo throw for channels 1, 2, 3 & 4 is

approximately 40 ˚and approximately 55 ˚for channels 5 & 6.)

To set the end points:

1. Enter the programming mode and use the MODE key to access the “EPA

EPA

”screen. The

channel number being adjusted will the left side on the screen and the % symbol will be

flashing.

2. To change the RIGHT aileron throw move the aileron stick to the right, then push the DATA

INPUT lever up or down to change the value and the throw.

3. Move the stick to the left and use the DATA INPUT lever to change the LEFT aileron throw.

4. Use the SELECT key to display the other channels and set the other end points. Notice that

moving the stick (or switch or dial) from one end to the other changes the value displayed and

the position of the arrow for that “end”of the control input.

TRIM - Trim Settings

There are four trim levers (“trims”) on the front of the transmitter. Three of the trims are for adjusting the neutral position of the

aileron, elevator and rudder servos. The fourth trim is for setting the idle r.p.m. of the engine when the throttle stick is all the

way down. The intended use of the trims is to make small servo adjustments, in flight, to get the model properly “trimmed”(so

it will fly straight-and-level). Because the trims are intended to be used while the model is in flight, you do not have to “enter

the program”to adjust the trims. Simply push or pull on the trim levers while flying and the neutral position of the servos will

shift. Keep in mind that you should start out with the control surfaces centered when the servos are centered and the trims are

“zeroed”(or near zero). THEN

THEN

you can adjust the trims once airborne.

Center the servos:

1. Turn on the transmitter and receiver. Operate the controls to make sure the servos respond in the correct direction. Use the

reversing function to reverse any servos necessary.

2. Center the throttle control stick.

3. Place the servo arms on the servos so they are perpendicular to the pushrods (see page 5). It is okay to cut off any unused

servo arms.

4. Connect the pushrods to the control surfaces. Adjust the length of the pushrods until the control surfaces are centered

when the servos are centered.

Note:

The throttle trim affects the throttle servo only when the throttle stick is below “1/2 stick.”This way, the final closing

of the carburetor can be adjusted without affecting the servo throughout the rest of the range.

To adjust the trim settings:

Once the servos and control surfaces have been connected and the control throws have been set using the end points and

dual rates, get the model airborne. Adjust the trims as necessary to get the model to fly straight-and-level. If much trim is

required on any one control it is a good idea to readjust the pushrods so the trims can be returned to neutral (zero). Adjusting

the trims with the trim levers changes the servo’s position in increments of “4.”If finer adjustments are required, land the

model, then enter the program as described below to adjust the trims in increments of “1.”

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.

PMIX Programmable Mixer

Unlike the “wing mixing”function (explained later) where the channels to be mixed are factory-set, the T6EXAP 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. Enter the programming mode. Access the “PMIX

PMIX

”screen with the MODE key.

2. Push the DATA INPUT lever upward. This will cause the flashing “INH

INH

”display to change to

a flashing “ON

”display.

3. Push SELECT key to call the screen for selecting channels to control “MAS

MAS

”(Master)

mixing. Then select the channel by pushing DATA INPUT lever . Channel 1 (aileron) in this

figure is assigned to the master.

4. Push SELECT key to call the screen for selecting channels to control “SLV

SLV

”(Slave) mixing.

Then select the channel by pushing DATA INPUT lever. Channel 4 (rudder) in this figure is

assigned to 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.

Wing Mixing Type Selection

With the programmable mix (previously described) the user determines the two channels to be mixed. The wing mixing

function is another mix that may be used, but the channels mixed are predetermined. There are three different wing mixing

functions to select from:

FLPR Flaperon mixing

This function allows the ailerons to be used both as ailerons and

and

as flaps. The

flap control dial (CH 6) operates the flap function. To use flaperon mixing both

ailerons must be operated by separate servos.

To activate flaperon mixing:

1. 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.

2. Enter the programming mode. Access the “FLPR

FLPR

”screen with the MODE key.

You cannot set “Flaperon

Flaperon

”mixing when “Elevon

Elevon

”mixing has already been set. In order to

enable “Flaperon

Flaperon

”mixing, you first need to cancel “Elevon

Elevon

”mixing. However, it is allowed

to use “Flaperon”and “V-Tail”mixing simultaneously.

*If necessary, use the Servo Reversing

function to achieve the correct direction of

servo throws.

3. Push the DATA INPUT lever upward. This will cause the flashing “INH

INH

”display to change to a

flashing “ON

”display. Now the mixing is on.

4. If needed to set ailerons differential. Press the SELECT key to display the flashing “%”sign.

Use the DATA INPUT lever to set the percentage of ailerons differential from -100% to

+100% (The “-”direction indicates decreasing amount of movement toward the upward from

the aileron surface, while “+”direction indicates decreasing amount of movement toward the

downward from the aileron surface.)

5. Once this mix has been activated, move the servos to their full extremes to make certain they are not overdriving the

controls. If necessary, adjust the linkages to achieve the correct control throws.

FLTR Flap trim

The Flap Trim function is used to specify the amount of flap travel produced moving the flap control (the Flap control dial).

As normal flap control dial will be inhibited to use if the flaperon function is activated, the Flap Trim function should be

activated if you need to control flap by Flap control dial.

To activate flap trim:

1. Enter the programming mode. Access the “FLTR

FLTR

”screen with the MODE key.

2. If “INH

INH

”is blinking, push DATA INPUT lever upward. Then you will see that the blinking

“INH

INH

”changes to “ON

”.Your flap trim is now turned on.

3. Set the travel of the flap control dial at between -100% and +100% by using DATA INPUT

lever.

V-TL V-tail mixing

Intended for V-tail aircraft (such as a Beechcraft Bonanza), V -tail mixing allows the ruddervators to operate both as rudders

and elevators. The same as the other mixes, V -tail mixing requires that each ruddervator be operated by a separate servo.

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.

2. Enter the programming mode. Access the “V-TL

V-TL

”screen with the MODE key.

You cannot set “V-tail

V-tail

”mixing when “Elevon

Elevon

”mixing has already been set. In order to

enable “V-tail

V-tail

”mixing, you first need to cancel “Elevon

Elevon

”mixing. However, it is allowed to

use “V-Tail”and “Flaperon”mixing simultaneously.

3. Push the DATA INPUT lever upward. This will cause the flashing “INH

INH

”display to change to a

flashing “ON

”display. Now the mixing is on.

4. Next you may the elevator setting. Press the SELECT key to display the “CH2”and flashing

“%”sign. Use the DATA INPUT lever to set the percentage of elevator travel rate from -100%

to +100%

5. Next you may the rudder setting. Press the SELECT key to display the “CH4”and flashing

“%”sign. Use the DATA INPUT lever to set the percentage of rudder travel rate from -100%

to +100%

6. Once this mix has been activated, move the servos to their full extremes to make certain they are not overdriving the

controls. If necessary, adjust the linkages to achieve the correct control throws.

*If necessary, use the Servo Reversing

function to achieve the correct direction of

servo throws.

CH1 CH2

ELVN Elevon mixing

Intended for tailless, “flying wing”models such as delta wings and flying wings,

elevon mixing mixes channel 1 (aileron) to channel 2 (elevator) allowing the

elevons to operate in unison (as elevators) or in opposition (as ailerons). This

function requires that each elevon be operated by a separate servo.

To activate elevon mixing:

1. Connect the servo in the right wing to channel 2 (elevator) in the receiver and connect the

servo in the left wing to channel 1 (aileron) in the receiver.

2. Enter the programming mode. Access the “ELVN

ELVN

”screen with the MODE key.

You cannot set “Elevon

Elevon

”mixing when “Flaperon

Flaperon

”or “V-TL

V-TL

”mixing has already been set.

In order to enable “Elevon

Elevon

”mixing, you first need to cancel both “Flaperon”and “V-tail”

mixing.

3. Push the DATA INPUT lever upward. This will cause the flashing “INH

INH

”display to change to a

flashing “ON

”display. Now the mixing is on.

4. Next you set the left wing to channel 1 (aileron) setting. Press the SELECT key to display the

“CH1”and flashing “%” sign. Use the DATA INPUT lever to set the percentage of elevator

travel rate from -100% to +100%

5. Next you set the right wing to channel 2 (elevator) setting. Press the SELECT key to display

the “CH2”and flashing “%”sign. Use the DATA INPUT lever to set the percentage of rudder

travel rate from -100% to +100%

6. Once this mix has been activated, move the servos to their full extremes to make certain they are not overdriving the

controls. If necessary, adjust the linkages to achieve the correct control throws.

*If necessary, use the Servo Reversing

function to achieve the correct direction of

servo throws.

F/S Fail Safe

(PCM mode only)

The Fail Safe function is used to prescribe what the PCM receiver will do in the event radio interference is received, and

doesn’t work FM(PPM) receivers. In this menu, you may select from one of two options of operation for each channel. The

“NOR”(normal) setting holds the servo in its last commanded position, while the “F/S”(Fail Safe) function moves each servo

to a predetermined position.

Throttle channel is set to “F/S”as a default. All the other channels are set to “NOR”.

The use of the failsafe function is recommended from the standpoint of safety. You may wish to set the throttle channel so

that the throttle is moved to idle when there’s interference. This may give enough warning to allow you to fly towards yourself

and recover from the radio interference. If you choose to specify a failsafe setting, the failsafe data are automatically

transmitted once each minute.

Battery Failsafe

Your system provides a second safety function called Battery Failsafe. When the airborne battery voltage drops below

approximately 3.8V, the battery fail safe function moves the throttle to a predetermined position or fast idle, if you haven’t set

it. If this happens, you should immediately land! If you need to increase throttle for your landing approach, you may

temporarily reset the failsafe function by moving the throttle stick to idle, after which you’ll have about 30 seconds of throttle

control before the battery function reactivates.

To set the Fail Safe Function:

1. Enter the programming mode. Access the “F/S

F/S

”screen with the MODE key.

2. You can find the channel blinking on the left of the screen, which can be set to the Fail Safe.

The first channel you see is CH1 (aileron). Press DATA Input lever downward when you

need to set Fail Safe. The arrow moves to F/S side. This means this channel has been set

to F/S function. Then move the aileron stick to the position where you want the servo to

move when “F/S

F/S

”function works and press DATA INPUT lever downward for about two

seconds while holding the stick. A figure in percentage will be shown with a beeping sound.

Press DATA INPUT lever upward if you want to set “NOR

NOR

”. The arrow moves to “NOR

NOR

”

side and then this channel will be set to “NOR

NOR

”function.

3. Carry out similar procedure like this in setting “F/S”function for other channels. Use Mode

key to show a channel and do the same. But, CH3 (throttle) is set to 20% of the full throttle

for “F/S”function as a default.

4. Verify that your failsafe programming works by switching off transmitter power and observing the motion of the servos.

OTHER 6EXAP 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 6EXAP to another 6EXAP with the small, square “micro”trainer jack, use the “Micro to Micro”(MM-TC)

trainer cord (FUTM4415). If connecting the 6EXAP to Futaba radios with the larger, round, “DIN”connector, use “Micro to

DIN”(MD-TC) trainer cord (FUTM4420). The T6EXAP transmitter may be connected to another T6EXAP, or any 4VF, 6VA

Skysport, T6EXA, 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 student's radio has PCM/PPM capability, set it to PPM.

3. If the student's radio has a plug-in RF module, remove the module.

4. Collapse the student's antenna and fully extend the instructor's antenna.

5. With the transmitters off, connect the trainer cord to both radios. (On the 6EXA the trainer

jack is in the center of the rear of the case.) Do not force the plug into the transmitter and

note that the plug is “keyed”so it can go in only one way.

6. Turn on the instructor's transmitter. DO NOT

DO NOT

turn on the students transmitter it will automatically “power up,”but will not

transmit a signal. Set the servo reversing and trims of the student's radio to match that of the instructor's.

7. Turn on the receiver switch in the model. Depress the trainer switch on the instructor's radio. Use the student’s radio to

operate the controls (ailerons, elevator, rudder, etc.) and observe how they respond. Make any adjustments necessary to

the student's transmitter to get the controls to respond correctly.

8. Check to see that the trims are in “sync”by toggling the trainer switch back and forth a few times. The controls on the model

should remain stationary. If the controls do not remain stationary, this indicates that the trim settings on the student's radio

do not match those on the instructor's radio. Adjust the student's trims as necessary.

Note:

When the instructor initially depresses the trainer switch on his transmitter, there will be a one-second delay before the

student takes control. In most situations this momentary delay will go unnoticed.

Throttle-cut function

The throttle-cut function is intended to be used for shutting off the engine. The engine can be conveniently shut off by pressing

the "THR Cut" button. The throttle-cut feature prevents inadvertently shutting off of the engine when lowering the throttle stick

all the way (such as when coming in for a landing or taxiing). Throttle-cut works only when the throttle stick is down. To set up

throttle-cut, turn on the transmitter and receiver. Actuate the throttle-cut function by rapidly depressing, then releasing the

switch twice. Observe the momentary position of the carburetor barrel on the engine. It should be fully closed (thus shutting off

the engine). If necessary, use the throttle E.P.A. (channel 3) to fully close the carburetor barrel when the throttle-cut is

activated. Now use the throttle trim to open the carburetor barrel so the engine will idle at the desired R.P.M. when the throttle

stick is all the way down.

Optional Flap control lever (Option)

When the flaperon mixing function is activated, the optional flap control lever

flap control lever

can be used to set maximum flap deflection by

mechanically limiting the dial. This will prevent inadvertently retracting the flaps beyond their full, "up" position. To use the flap

control lever, turn the flap dial until the flaps are retracted (up). Place the flap control lever over the dial so that the arm is

contacting the transmitter case. This will limit rotation of the dial so the flaps cannot go up any farther.
