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 beginneror sportsystem with the requirements of those flyers in mind, in order to make the best use of your Futaba 6EXA and to operate it safely, you mmust ccarefully rread aall oof tthe iinstructions . 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. 2 Introduction ...................................................................................2 Service ............................................................................................2 Contents aand sspecifications .......................................................3 Glossary .........................................................................................3 Introduction tto tthe 66EXA ssystem ...............................................4 Transmitter ccontrols aand ddescriptions ......................................4 Radio iinstallation .........................................................................5 Receiver aand sservo cconnections ................................................7 Charging tthe NNi-CCd bbatteries ......................................................7 LCD aand PProgramming ccontrols .................................................8 Programming tthe TT6EXA rradio ..................................................9 Model select/Data reset ....................................................10 Servo reversing ....................................................................10 Dual rates .............................................................................10 Exponentials.........................................................................11 End Point Adjustments.......................................................11 Trims......................................................................................12 Programmable Mixer..........................................................12 Pre programmed “wing” mixing .......................................13 Flow chart.............................................................................16 Other TT6EXA ffunctions ..............................................................17 Trainer switch.......................................................................17 Flap control lever .................................................................17 Adjustable-length control sticks .......................................18 Changing the stick mode...................................................18 Flying ssafety gguidelines ............................................................18 Flight ppreparation ......................................................................19 Frequency CChart .........................................................................20 Futaba AAccessories ....................................................................20 Model DData RRecording SSheets .................................................21 TABLE OOF CCONTENTS This product is to be used for sport and recreational flying of radio-control models only.

INTRODUCTION TTO TTHE 66EXA SSYSTEM 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 The T6EXA FM 6-channel transmitter may be used with any Futaba, narrow band, FM receiver. 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 or flaperon + V-tail mixing may be selected. Transmitter ccontrols The diagram and explanations briefly describe the functions of the Futaba T6EXA 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 18). DESCRIPTIONS: Aileron aand EElevator ddual rrate sswitch 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 ccontrol ddial/Channel 66 - 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 sstrap hhook - Mounting point for optional neck strap. Aileron/elevator ccontrol sstick - Operates the servos connected to channel 1 (aileron) and channel 2 (elevator) in the receiver. Trim llevers ((all) - Used to shift the neutral or centerposition 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 Aileron & Elevator dual rate switch Antenna Retractable landing gear switch / CH.5 Flap control dial / CH.6 Carrying handle Liquid-crystal display screen (LCD) Throttle/rudder control stick MODE key SELECT key Trainer /throttle cut switch Neck strap hook Charging jack On-off switch Rudder trim lever Throttle trim lever DATA INPUT lever Aileron trim lever Elevator trim lever Aileron/elevator control stick Charging jjack – Port for charging the transmitter batteries with the included battery charger. On-ooff sswitch DATA IINPUT llever – Used to change the values of the various functions displayed on the LCD screen. Liquid-ccrystal ddisplay sscreen (LCD) – Displays programming modes and values entered. MODE kkey - Used to scroll through and display the seven different functions. SELECT kkey - Used to display the values for the current function. Throttle/rudder ccontrol sstick - Operates the servos connected to channel 3 (throttle) and channel 4 (rudder) in the receiver. Trainer/throttle-ccut sswitch - 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 llanding ggear sswitch/Channel 55 – 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 IINSTALLATION Follow these guidelines to properly mount the servos, receiver and battery. • Make certain the alignment ttab 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 ggrommets . 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. 5 • After the servos ar…

MODEL —— MModel SSelect/Data RReset Model sselect ffunction 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 rreset ffunction 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 rreset ddata: 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 —— SServo RReversing 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 ccertain 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 rreverse aa sservo: 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 —— DDual RRates/Exponential SSettings 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: When performing initial model setup, the E.P.A.s should be set prior tto 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%. 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. 10 Dual RRate SSettings To sset tthe ddual rrates: 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 SSettings 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 sset tthe eexponentials: 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. E.P.A —— EEnd PPoint AAdjustment 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 …

Johnson American TCB 2003-03-17 In reference to FCC ID AZPT6EXA-72 1. The block diagram has been amended as requested . 2. A confidentiality letter will be uploaded . 3. Pulse position modulation means the positition of pulses or “1” levels in a data train. The modulation is true FSK modulation. We have corrected the technical description accordingly. 4. DC Voltage/Current supplied to the final RF amplifier is 9.6 V DC / 66.3 mA. 5. Since setting the frequency by changing crystals by the user is not allowed, TX frequency will be preset in the factory. 6. The operational description has been corrected accordingly. 7. The conducted RF power is most representative. It has been measured with an impedance matching network connected between antenna output of the transmitter and the power meter. The schematic diagram of this network is shown in the report. The EUT is a handheld device operating at relative low frequency = long wavelength compared with the EUT dimensions. This results in poor antenna efficiency when tested in stand alone condition. Under normal operation condition the human body will act as “counterweight” to the antenna and will improve antenna efficiency.. Johann Roidt Senton GmbH
