• Always turn on the transmitter first, then the receiver. When turning the system off always remove power from the receiverfirst, then the transmitter. It is NEVER safe to have power applied to the receiver only, as the model’s motor and servos maybe uncontrollable and become unsafe or damaged.

• Do not operate the transmitter on a frequency which is already being used in your area, as it could cause interference and behazardous to another modeler.

• Do not fly in the rain or at night. Water can permanently damage many of the components in the radio system, possiblycausing loss of control and a crash.

• Fly at safe distances away from other people, buildings, electrical lines, or any other object which could possibly impede safeflying. Failure to do so could cause a crash and bodily harm, and physical damage to property.

• Always extend the Tx and Rx antennas to maximum length when flying. Make sure the Tx antenna is screwed into the Tx tightly. Mountthe Rx antenna in your model so that it does not drag on the ground. Always range test the radio system before use.

• Adjust the transmitter’s throttle stick to minimum position BEFORE turning the Tx’s power switch “ON”. Failure to do so couldcause the engine to go to full throttle and cause an injury.

• Do not make adjustments to the radio system while the engine is on unless absolutely necessary. Failure to do so could causethe engine to accidentally go to high speed and cause an injury.

• During flight preparations, always place the Tx on its back when on the ground, to prevent it from accidentally falling over andinadvertently moving the throttle stick.

• Always attach the proper frequency flag to the Tx’s antenna when flying. This alerts others at the flying field as to whichfrequency you are using.

• Always fully charge the Tx and Rx NiCd batteries before each flight. Failure to do so could cause an inadvertent power failureand a crash.

• Do not leave the radio system, batteries, model airplane, or other modeling equipment within the reach of children.

• Do not overheat or throw the NiCd batteries into a fire. Leaking electrolyte from the battery could cause injury, such as burnsor blindness. IN CASE OF EMERGENCY, IMMEDIATELY FLUSH YOUR EYES SKIN, OR CLOTHES WITH PLENTY OFWATER AND SEE A DOCTOR. Recycle the battery when no longer in usable condition (see page 20).

• Store the radio with all NiCd batteries in the discharged state, and be certain to fully charge the batteries just prior to use.

• Do not store the radio system in extreme heat (exceeding 104oF) or cold (below -14oF), in direct sunlight, in high humidity, inhigh vibration environments, or in dusty areas.

• Do not allow fuel or oil on the plastic parts. Some plastics may melt when exposed to such materials.

Understanding the following terms will be very helpful before reading the rest of the manual.

REVERSING (SERVO REVERSING): Changing a servo’s rotational directionthrough the transmitter’s “reverse” display.

THROW: Control surfaces (aileron, elevator, rudder, etc.) are designed to movecertain distances in different types of models. This movement distance is referredto as “throw”, typically measured at the trailing edge of the surface and expressedin inches or millimeters as shown in Figure 1.

Figure 1

GLOSSARY

CAUTIONS

WARNINGS!

4

DUAL-RATE (D/R): Dual-rates allow you to instantly switch between two different control throws (distances) for the aileron andelevator. Different flying styles can often require different throw lengths for the controls. For models moving at high speeds, “low”throw settings make the control surfaces seem less sensitive. For models which are being flown slowly, such as during landings,or those being flown with very aggressive aerobatic maneuvers, “high” throws may be necessary as the model’s control surfaceswill not seem sensitive enough.

END POINT ADJUSTMENT (E.P.A.): This determines the absolute maximum throw or distance that a servo can rotate. E.P.A.settings are separate from dual-rate settings. Regardless of the transmitter’s D/R settings, the servo will never travel beyond theE.P.A. limit set in the transmitter.

EXPONENTIAL: Without exponential, servos normally move equally proportionately to the movement of the transmitter’s controlstick. For example, moving a Tx stick gradually will cause the servo to move equally as gradually. With exponential control, theservo moves disproportionately (either more or less) to the rate at which the Tx stick is moved. For example, with a linearmovement in the Tx stick, the servo can be set to move at a speed which is initially the same as the movement of the stick butquickly becomes faster or slower than the movement of the stick. Exponentials are commonly used to “soften,” or decrease initialservo travel for the ailerons and elevators, so that initial control stick inputs from the pilot result in small servo movement for asmoother flying airplane. Note: Dual rates adjust the amount of servo travel, whereas exponential determines where most of thetravel will occur.

MIXING: Sometimes it’s desirable to make two (or more) servos move simultaneously from only a single movement of atransmitter’s stick. This is called “mixing” and can be done by mechanical means (physically connecting the wires of the servos tobe mixed with a Y-connector), or electronically through the 6XM’s programming (no physical connections exist between theservos). Setting mixes in the Tx allows for more flexibility for varying applications, as servos can be made to move in oppositedirection of each other, each servo’s end points can be set independently, etc.

THE TRANSMITTER

The Tower 6XM transmitter (Tx) can be used with any Tower Hobbies or Futaba® brand narrow-band, FM receiver (Rx). The 6XMcontains independent memories for six different models. External switches operate dual-rates and exponentials, landing gear, andtraining functions. Programming features include: servo reversing and end point adjustments for all channels, dual-rates andexponential controls for aileron and elevator channels, plus five programmable mixes - four factory pre-set mixes includingflaperon, V-tail, elevon, or flaperon + V-tail, and one user-defined programmable mix.

During normal conditions, the range, or safe operating distance from the 6XM Tx to the Rx is “line of sight”. This means the 6XMshould maintain complete control any time you can see the model. The 6XM operates on the 72MHz frequency band, in whichthere are 50 different channels ranging from 72.010MHz (Ch11) through 72.990MHz (Ch60). For safety reasons, you must alwaysbe aware of what channel you are using, and place the included frequency flags on your Tx any time while in use, so that no tworadios on the same frequency are functional in the same area at the same time.

AILERON AND ELEVATOR DUAL-RATE/EXPONENTIAL SWITCH: Moving this switch changes between the two dual-ratesettings for the aileron and elevator channels. The throws can be custom set to match personal preferences or particular aircraft.This switch also flips between exponential rates (if used).

FLAP CONTROL DIAL / CHANNEL 6: Controls the servo connected to channel 6 in the receiver, and is often used to controlairplane flaps if applicable.

NECK STRAP HOOK: The included neck strap clips onto this hook.

AILERON / ELEVATOR CONTROL STICK: Controls the servos connected to Rx channels 1 (aileron) and 2 (elevator). Aileronmovement is controlled with horizontal movement of this stick. Elevator movement is controlled with vertical movement of thisstick.

DIGITAL TRIM LEVERS: Used to finely adjust the neutral or center position of the servo in each respective channel. This ishelpful to “dial in” the model’s surfaces for easier control. The 6XM’s trim controls are digital, as opposed to mechanical leverswhich are found on most lower-cost or older radios.

CHARGE JACK: Input port for connecting the charger, to charge the battery while it’s inside the transmitter.

ON-OFF SWITCH: For turning the Tx’s main power on and off.

LIQUID CRYSTAL DISPLAY (LCD) AND PROGRAMMING CONTROLS: For viewing Tx operating parameters and adjustingcontrol settings.

THROTTLE / RUDDER CONTROL STICK: Controls the servos connected to Rx channels 3 (engine/motor throttle) and 4(rudder). Rudder movement is controlled with horizontal movement of this stick. Throttle movement is controlled with verticalmovement of this stick.

TRAINER / THROTTLE CUT SWITCH: Operates the trainer and throttle cut functions.

RETRACTABLE LANDING GEAR SWITCH / CHANNEL 5: Controls the servo connected to channel 5 in the receiver. If themodel has retractable landing gear, moving this switch will extend and retract the gear.

ANTENNA: The transmitter emits its signal through the antenna. The antenna may be removed and replaced with another incase it is inadvertently broken.

FREQUENCY FLAGS: This radio system transmits a signal on a pre-set frequency, or “channel”. Your frequency (noted as “MHz”)and two-digit channel number are marked on the outside of the 6XM’s box. The frequency can also be identified by looking at thecrystal on the rear of the Tx, and the top of the Rx. All channels and corresponding frequencies in the 72MHz band are as follows:

SERVOSMount all servos in the model according to the airplane’s instruction manual. Be cautious of thefollowing points when installing servos:

1. Always use the rubber grommets, screws, and brass eyelets supplied when mounting theservos in the airplane (see Fig. 3). Install a rubber grommet to each mounting lug on the servo.Insert a brass eyelet to the bottom of each grommet. Insert a screw down through the hole ineach rubber grommet and to the mounting surface. Do not over-tighten the mounting screws.Servos should be allowed to move slightly to compensate for vibrations within the model.

2. Use a servo horn which is long enough to accommodate the entire range of movement forthat particular control.

3. If a servo wire is too short to reach the receiver, insert a servo extension (available separately through Tower Hobbies, see page20) in-between the servo and Rx.

4. No part of a servo’s case should make contact with the actual mountingsurface, servo tray or any other part of the airplane structure. Otherwise,vibration will be transmitted to the servo and cause premature wear and/orservo failure.

5. To mechanically center the servo’s output arm, connect the servo to theRx and turn on the Tx and Rx. Make sure the Tx’s sticks and four mainchannel trims are at central position (see Fig. 4). Then, use an output armwhich can be mounted perpendicular to the pushrod when it is placed ontothe servo.

6. After installation, operate each servo over its full travel and inspect thepushrods and servo arms to ensure they are not binding in any way. Make sure the controls do not require excessive force tooperate. If there is a noticeable buzzing sound coming from a servo there is probably too much resistance against its output arm.This can cause excessive wear on the servo, inaccurate control, and quickly drain the receiver battery. Find and correct theproblem and re-check.

SWITCH HARNESS AND RECEIVER BATTERYTo mount the switch harness to the airplane, choose a location on the fuselage which is free from exposure to contaminants suchas engine oil, dirt, dust, and so on. Mounting the switch on the side of the fuselage opposite the muffler is best. It’s a good ideato mount the switch in a location which will not accidentally be turned on or off during handling or storage.

Using the switch harness’ own mounting plate as a template, mark and cut holes in the side of the fuselage for the switch harnesslever and for the mounting screws. Make sure the holes closely match the dimensions of the switch harness’ mounting plate sothat the switch lever snaps freely in both directions, but does not interfere with the area around the holes for the mounting screws.

Make sure the switch harness lever is in the “OFF” position. Plug the switch harness’ red connector into the Rx channel markedwith a “B”. Connect the Rx battery to the female lead on the opposite end of the switch harness. The remaining lead on the switchharness is for connection of the charger so the Rx battery can be charged directly through the switch harness for convenience.

RECEIVERConnect each servo to the Rx as shown in Fig. 5. Always insert the servo and battery or switch harness connectors into the Rxfirmly, to ensure solid physical and electrical connections are made. When connecting devices to the slots in the Rx, make certainthe alignment tab on all connectors are properly aligned with the “key” or notch in the slot in the Rx. When unplugging connectors,never pull on the wires themselves - always pull on the plastic connector only. Otherwise, damage to the wiring could result. Thereis a slot in the Rx for every channel in the Tx, designated as follows:

Figure 5Rx slot Function1 Aileron, or right flaperon, or right elevon (for tail-less models)2 Elevator, or left ruddervator (for V-tail models), or left elevon (for tail-less models)3 Throttle4 Rudder, or right ruddervator (for V-tail models)5 Retractable landing gear6 Flaps, or left flaperon7 Not usedB/8 Rx battery or switch harness

After all servos and the battery or switch-harness are connected, the Rx should be protected from vibration, shock andtemperature extremes by wrapping the Rx in foam rubber or other vibration-absorbing material (Tower part numbers HCAQ1000or HCAQ1050). In areas of high heat and humidity, especially near large bodies of salt-water, seal the Rx against moisture (water,fuel, exhaust, etc.) by placing it in a plastic bag and closing the open end with a rubber band before wrapping it in foam. To helpprevent the Rx from becoming damaged or disconnected from any other components, fasten it to the inside of the airplane withVelcro® or a rubber-band.

RECEIVER ANTENNATo achieve maximum operational range and clear signal reception, NEVER cut the receiver’s antenna, or coil or mount it in themodel folded backwards. The antenna must be extended to its maximum length. The receiver antenna may be mounted insideor outside the model.

Mounting the antenna inside the model: The antenna may be routed down through the inside of the fuselage, or through anynon-metallic housing or tube within the fuselage. To prevent unwanted electro-mechanical interference (EMI), keep the antennaas far away as possible from engines/motors, servos, metal pushrods, wires and cables.

To mount the antenna outside the model:A. Cut a small hole in the fuselage to exit the antenna wire. Make a

“strain relief” for the antenna wire by cutting off the end of an unusedservo arm (see figure 6). Feed the antenna through two or three holesin this strain relief, then guide the antenna through the exit hole in thefuselage. Make sure there is enough slack in the wire between thelocation of the Rx and the exit hole to keep the antenna fromaccidentally being pulled out of the receiver. If possible, insulate thehole with a rubber grommet or a small piece of rubber tubing.

B. Cut off the end of another servo horn to act as a hook. Insert theend of the antenna through two holes in the hook as shown in Figure6. Connect the hook to the airplane’s vertical stabilizer with a rubberband that is wrapped around a T-pin. Allow any excess antenna lengthto trail behind the hook, but don’t let the antenna drag the ground.

CHARGING BATTERIESOne of the most common causes for crashes is improperly or inadequately charged radio batteries, especially the Rx battery. Therechargeable NiCd (nickel-cadmium) batteries inside the Tx and the Rx pack come from the factory with only a partial charge andwill require a full charge before attempting to fly the model. Make sure the radio batteries are charged overnight with the includedcharger the night before you go to fly. The 6XM Tx has a built-in voltage indicator, so it’s simple to determine the condition of theTx battery (see Fig. 8 on page 10). If you are uncertain about how much charge is left on your Rx battery, it’s best to err on theside of caution and check the voltage of the battery before flight. The easiest way to accomplish this is to check the battery withan expanded scale voltmeter. Tower Hobbies’ Expanded Scale Voltmeter MkII (TOWP1181) can check this battery voltage whileapplying a realistic load on the battery.

1. Plug the A/C wall charger into a standard 110V AC wall outlet.

2. Connect the charger’s round plug to the charge jack on the right side of the Tx. The Tx’s power switch must be in the “OFF”position for the battery to accept a charge. The charger’s “Tx” LED will illuminate to indicate that a charge is being delivered tothe battery.

3. Connect the charger’s square plug to the Rx battery. This can be done in 2 ways: (a) connect the charge cord directly to thebattery pack, or (b) if the Rx battery is already connected to the switch harness, connect the charge cord to the vacant connectoron the switch harness. The charger’s “Rx” LED will illuminate to indicate that a charge is being delivered to the battery.

4. Batteries which had been fully discharged will take about 15 hours to fully charge. Charge each battery for 15 hours with thesupplied wall charger. The batteries may become warm as they charge, this is normal. When charging is complete, disconnectthe charge leads from the batteries, and disconnect the charger from the wall.

If using an aftermarket fast charger to charge the batteries be certain to follow the instructions provided with the charger so not toovercharge the batteries. It is NOT recommended to exceed a fast charge rate of 1.0 amp on the 6XM’s batteries. The batteriesshould also be discharged or cycled periodically to keep them in optimum operational condition. Cycling should be done everyone to two months, even during the winter or periods of long storage. If using a cycler with a readout, note the capacity after thebatteries have been cycled. If the Tx or Rx battery has been cycled multiple times in succession and the cycler shows that thebattery will not deliver over 80% of its rated capacity the batteries may need to be replaced.

SYSTEM CHECK AND RANGE TESTAfter the switch harness, battery, and all servos are properly connected perform a simple system check to ensure everything is inproper working order.

First turn “ON” the Tx power switch, then the Rx. With all sticks and trims at center position, make sure all servos operate in theproper directions according to the movement of the Tx stick. The control surfaces should be at neutral position when the sticksare at center. If neutral position of the control surface has been changed, even though the stick is still at center, change the lengthof the pushrod by adjusting the clevis on the end of the rod. Make sure each control surface is set according to the airplane’sinstructions.

For engine throttle, set the position of the servo horn so that the engine’s throttle is opened fully when the Tx throttle stick is atmaximum (up), and is closed fully when the Tx’s throttle stick and trim are at minimum (down).

Once all controls and linkages are confirmed it’s time to range test the radio. It is important to range-check your system prior tothe first flight of every new model. It’s not necessary to do a range check before every flight, but is a good idea to perform a rangecheck before the first flight of each day.

1. Turn on the Tx, then the Rx.

2. With the Tx antenna collapsed, Rx antenna fully extended, and the model sitting on the ground, walk away from the modelwhile operating the controls. Smooth movement of all control surfaces on the model should be achieved from at least 100 feetaway (20 to 30 paces) from the Tx. If jittering occurs, or if control of the Rx is completely lost, refer to the Troubleshooting Guideat the end of this manual before proceeding.

3. If everything operates correctly, prepare to start the engine. Set the Tx in a place that is easily accessible, yet far enough awaythat it will not make contact with the airplane’s rotating propeller. Make sure the Tx’s throttle stick is all the way down.

4. Start the engine.

9

5. Perform another range check with an assistant holding the plane, and operate the engine at various speeds. If the servos jitteror move inadvertently there may be a problem. Do not fly the plane! Look for loose servo connections or binding pushrods. Alsobe certain you are the only one on your frequency, and that the battery has been fully charged. Refer to the Troubleshooting Guidein the rear of this manual for more information.

6. Attach the included “frequency flags” to the Tx antenna before every flight. Peel the backingfrom the frequency number stickers and apply them to both sides of the plastic clip as shownin Fig. 7. Snap the end of the clip to the base of the antenna as shown. IMPORTANT: It’scritical that everyone at the flying field knows which channel you are using when flying!!Only ONE RADIO can be used on a single frequency at any one time. If you turn on yourTx while another person is flying on the same frequency, a crash will likely result which couldalso pose a risk of bodily harm to anyone nearby. NEVER turn on your Tx until you havepermission from your instructor, and you have possession of the frequency clip from thefrequency board at your site.

Once all necessary changes have been made and all range checks have passed, prepare forflight. Fully extend the transmitter antenna. Avoid pointing the antenna directly at the model asthe signal is weakest in that direction.

SCROLL MENU button: To scroll through different setup menus in the display.

SELECT CHANNEL button: To select values and channels on the LCD to be set or changed.

To enter the programming mode, press BOTH the SCROLL MENU and SELECT CHANNEL buttons simultaneously and holdfor one second.

ADJUST VALUES lever: To adjust settings or values of the various functions on the LCD.

LIQUID CRYSTAL DISPLAY (LCD): When the Tx is initially turned on, the model memory number (1 through 6) and Tx batteryvoltage values are displayed on the LCD. When prompted by the user as described throughout the remainder of this section ofthe manual, different functions and settings in the memory can be displayed on screen.

TRANSMITTER BATTERY VOLTAGEThe transmitter’s own operating voltage is shown on the bottom of the screen in “v” or volts. This is the voltage of the NiCd batterywhich is stored inside the small door on the rear of the Tx case. When this voltage drops below approximately 8.5 volts the LCD’sbattery icon (shown above) will flash and the low-battery alarm will continuously “beep” until the Tx is turned off. The low-batteryalarm is a warning that the Tx will lose all power in approximately four minutes (or maybe less), and you should land your modelimmediately before losing control. As a rule of thumb, NEVER fly a model if the Tx voltage is below 9.5V. Fully charge the Txbattery before flying.

When actually setting up a model you should have the model in frontof you with the power on so you can actually see the effects of your programming inputs and measure the control throws. If youwill not be using any mixing functions you can skip that section until which time you will use them. To begin studying theprogramming functions, turn on the Tx and enter the programming mode and proceed below.

“MODEL” – MODEL MEMORIESThe 6XM can store parameters for six models in memory. This means any control settings (E.P.A values, trim settings,programmable mixes, etc.) for up to six different models can be stored in memory and re-called at any time. This makes it veryquick and easy to prepare the Tx for any of six different airplanes at any time.

Once a memory has been programmed, it’s a good idea to record that information in the chart at the end of this manual so youcan have a permanent record which can be referred to in the event of a problem with the internal power system in your Tx or ifyou accidentally erase the settings for a model.

To select a model memory:

1. Enter programming mode (press and hold the SCROLL MENU and SELECT CHANNEL buttons).

2. “MODEL” will show on the LCD and the memory number for the currently active model will beflashing.

3. To change to a different model memory press the ADJUST VALUES lever up or down to find thedesired memory number. All programming now viewed on the LCD will be for this model memory untilthe model number is changed again.

IMPORTANT! When the Tx is turned ON make sure the model number matches the proper airplane. Failure to do so could causeimproper control and operation of the airplane and lead to a crash, and could pose a significant safety hazard. It might be helpfulto tape a small quick reference chart on the rear of your Tx or your flight box to list which model number in the Tx’s memorymatches which airplane that you have.

DATA RESET FUNCTIONAll data for any one model memory can be reset at any time to the original factory default. This function is useful when you wantto remove the programming for one type of model and enter parameters for a new model. To reset data:

1. Enter programming mode. In the “MODEL” screen move the ADJUST VALUES lever up or down tofind the model memory number you wish to reset.

2. Press the SELECT CHANNEL button, and “CL” will show on the LCD.

3. Press the ADJUST VALUES lever up or down and hold for two seconds. “CL” will briefly flash, thenstop flashing which will indicate that this memory has been cleared to factory default.

CAUTION: Resetting a model memory will PERMANENTLY ERASE ALL programming parameters forthat model. That data cannot be recovered.

“REVERSE” – SERVO REVERSINGThis function changes the rotational direction of a servo’s output. For example, if moving a Tx stick upwards causes the servo torotate counter-clockwise, reversing the servo rotation setting in the transmitter’s programming means that moving the Tx stickupwards will now cause the servo to rotate in a clockwise direction. After reversing any channel be sure to check the model’scontrol surface to make sure it’s operating in the proper direction. Reversing direction of the wrong servo (and not checking itbefore flight) is a very common cause of a crash! To reverse a servo:

1. Enter the programming mode.

2. Press the SCROLL MENU button to find the “REVERSE” screen.

3. Use the SELECT CHANNEL button to find the channel that you wish to reverse. The channelnumber at top-right will be flashing on screen.

4. Move the ADJUST VALUES lever down to reverse the servo’s rotation. The direction arrow on-screen will move next to the “REV” indicator. Or, move the lever upward to make the servo rotate inthe normal direction, and the arrow will move next to the “NOR” indicator.

5. Use the SELECT CHANNEL button to display other channels to be reversed. Or, press and hold theSCROLL MENU and SELECT CHANNEL buttons to return to the main screen.

“D/R” – DUAL-RATES AND EXPONENTIALSThe dual-rate controls for the aileron and elevator channels (1 and 2) are controlled by the SAME switch above the right stick.Moving the switch will change the dual-rates for both channels at the same time. However, the amount of change in servo travelfor each channel can be programmed independently.

The amount of deflection for each channel is based on a percentage of the servo throw that is set in the End Point Adjustmentscreens (see page 14), and may be set between 0% and 100% of the EPA values. Note: When first setting up a model, set theEPA adjustments before setting the dual-rate settings. When setting the EPAs on a new model for the first time, the dual-ratesshould be set to 100%. It’s possible to set a dual-rate value to 0% which would effectively cause that channel to be inoperative,and could result in a crash.

To set the dual-rates and exponentials:


2. Press the SCROLL MENU button to find the “D/R” screen that also shows a “%” value.

3. The dual-rate settings for channel 1 (aileron) will be displayed. If you don’t wish to adjust the dual-rates for the ailerons press the SELECT CHANNEL button to find “CH2” for elevators. Note: If thepercent value disappears and a “+/-“ sign appears you have pressed the SELECT CHANNEL buttontoo many times. Press the SELECT CHANNEL button repeatedly until the “D/R %” screen returns.

4. Dual-rate values for the up and down switch positions are set independently, and that moving this switch will also cause thearrow icons on-screen to move as well. Place the switch in the desired position. Move the ADJUST VALUES lever up or down tochange the dual-rate throw percent until the desired control throw percentage is achieved. Repeat this for both switch positions.TIP: Generally, pilots prefer to have the switch in the “up” position for the high throw rate and in the “down” position for the lowthrow rate.

5. If dual-rates for the aileron channel have been set, press SELECT CHANNEL to set dual-rates for the elevator (CH2) and repeatstep 4.

6. Skip to step 10 if you do not wish to change EXPONENTIAL settings. Otherwise, setting the exponential functions isperformed very similarly to setting the dual-rates.

7. Press the SELECT CHANNEL button to find the “D/R” screen that also shows a “+/-” value for channel 1 (ailerons). If you don’twish to adjust the exponential for the ailerons press the SELECT CHANNEL button to find “CH2” forelevators. Exponential values for the up and down switch positions are set independently, and thatmoving this switch will cause the arrow icons on-screen to move as well. Negative exponential (-)decreases initial servo movement, but rapidly increases servo movement as the Tx stick is movedfarther away from center. Positive exponential (+) increases initial servo movement, but decreasesservo movement as the Tx stick is moved farther away from center. The exponential “curve” may beset anywhere between -100% and +100%.

8. Place the dual-rate switch in the desired position (up or down). Move the ADJUST VALUES lever upor down to find the desired exponential value. To change the exponential percentage for when theswitch is in the opposite position, flip the switch, then use the ADJUST VALUES lever again to change the exponential percentage.

9. If exponential for the ailerons has been set, press SELECT CHANNEL and repeat step 8 to set exponential for the elevator(CH2).

10. Press and hold the SCROLL MENU and SELECT CHANNEL buttons to return to the main screen.

“E.P.A.” - END POINT ADJUSTMENTSThis feature is designed to set the absolute maximum amount of throw or rotation that a servo can achieve. This can be helpfulfor when you may need to limit the amount of servo throw to keep a pushrod from binding or to keep from pushing a control surfacetoo far which could damage the model.

The pushrods should first be connected to the servo arms and control horns so that the proper amount of deflection can beachieved on the model. Adjust the end point adjustments can be made in the Tx to make small changes in the servo throw untilthe desired control throw is achieved. The throws should be set so that the end points are as close to 100% as possible. If theend points must be set below 70%, or above 120% to get the desired throw it would be a good idea to adjust the pushrodconnections so that the end points can be set more closely to 100%. Note: When the end point adjustment for any channel is setto 100% the maximum throw for the servo is approximately 40° for channels 1 through 4, and approximately 55° for channels 5and 6. Changing the end points will also cause a change in servo throw when using the dual-rate function. For this reason, theend points should be set before setting the dual-rates. To set the end points:


2. Press the SCROLL MENU button to find the “E.P.A.” screen.

3. The E.P.A. settings for channel 1 (aileron) will be displayed on the top-right side of the screen. If youdon’t wish to adjust the E.P.A. for the ailerons press the SELECT CHANNEL button to find “CH2” forelevators.

4. Note that TWO end point settings exist for every channel - one setting for each end of throw. A smallarrow indicator is located above and below the channel number. Moving the stick for the channelshown from one end to the other will cause the arrow indicator to move as well. So, for the aileronchannel, moving the right stick to the far right will cause the arrow to point in one position, and movingthe stick to the far left will cause the arrow to reverse direction. End points can be set for both positionson all channels.

5. Move the control for the selected channel to one side and hold, then press the ADJUST VALUES lever until the desired E.P.A.value is found for that direction. Then move the control for that channel to the opposite side and repeat.

6. Use the SELECT CHANNEL button to find all other channels to adjust, and repeat as needed.


Note: A flap control lever is included with the 6XM. This lever can be used to mechanically limit the rotation of the dial, which canhelp to prevent accidentally retracting the flaps beyond their full “up” position. To use the flap lever, turn the flap dial until the flapsare fully retracted (up). Slide the flap control lever over the dial so that the end of the lever is making contact with the Tx case.This will prevent the dial from being over-rotated past the full up position of the flaps.

“TRIM” – TRIM LEVERS AND FINE ADJUSTMENTS OF THE TRIM SETTINGSThere are four digital trim levers on the front of the transmitter, one for each of the four main channels. The purpose of the trimsto make very fine adjustments to the position of the servo outputs. Trims can be adjusted while the model is on the ground, orduring flight to help the model fly straight and level. Briefly pushing the trim buttons (up and down, or left and right) will adjust theservos. Three of the trims are for adjusting the neutral position of the aileron, elevator and rudder servos. The throttle trim is usedto set the idle R.P.M. of the engine when the throttle stick is all the below ½ stick, so that the final closing of the carburetor can beadjusted without affecting the servo throughout the rest of the range of rotation.

Note: The trims are electronic and not mechanical. Do not attempt to force the trim levers past their stops. Each push of a trimbutton will create a “beep” to confirm operation.

In the beginning, it’s best that the control surfaces are centered physically on the model, while the servos themselves are centered,and the transmitter’s trims should be centered as well (would be displayed as “+/- 0” on the LCD). Then, once airborne you canre-trim the channels as necessary to achieve stable flight. To center the servos:

1. Turn on the Tx and Rx. Operate the controls to make sure the servos respond in the correct direction. If necessary, use the6XM’s reversing function to reverse the direction of any servos (see page 12).

2. Center the throttle control stick.

3. Place the arms on the servos so they are perpendicular to the pushrods (see Fig. 4 on page 7). It is okay to cut off any unusedservo arms.

14

Figure 15

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

To adjust the trim settings:

Once all servos / control surfaces have been connected and all end points and dual rates have been set, get the model airborne. Whilein flight, adjust the trims for each main channel as necessary so that the aircraft will fly straight and level. If a lot of trim is required tocorrect any control it may be necessary to land the model and re-adjust the pushrods for that control so that the trim can be returned toneutral (zero). Adjusting the trim levers will change the servo’s position in increments of “5” as seen on the LCD.

If finer adjustments are required, land the model, then enter the programming mode as described below to adjust the trims inincrements of “1.”

1. Enter the programming mode, and press the SCROLL MENU to find the “TRIM” screen.

2. Press the SELECT CHANNEL button to find the channel you wish to adjust.

3. Move the ADJUST VALUES lever up or down to adjust the trim as needed.

4. Repeat these steps to finely adjust the trim for any other channels.


“P.MIX” – PROGRAMMABLE MIXThe 6XM includes one use-definable or “programmable” mix whereby control for one channel can becustom designed to mix with another channel. Sometimes airplanes with unique wing designs requiresome mixing for proper control. Other times, mixes can be used to correct irregular flight tendenciesof the model. To set up a user-defined programmable mix:


2. Press the SCROLL MENU button to find the “P.MIX” screen (see figure 17).

3. The “INH” or inhibit indicator will be flashing. Press the ADJUST VALUES lever up to turn theprogrammable mix “ON”.

4. Set the “master” channel – the channel which will control the mix. Press the SELECT CHANNELbutton twice to find a channel number with the arrow above it (to denote the master channel). Pressthe ADJUST VALUES lever to select which channel to be the master (see figure 17A).

5. Set the “slave” channel – the channel that will be controlled by the mix. Press the SELECT CHANNELbutton again cause the arrow to now point down (to denote the slave channel). This channel will be affectedby movement of the channel listed in point 4 above (the “master” channel will affect the “slave” channel). Pressthe ADJUST VALUES lever to select which channel will be the slave (see figure 17B).

6. Press the SELECT CHANNEL button twice to find the “P.MIX” display that shows a percentage value.This is where you set the how much the master channel will affect the slave channel in the mix. Movethe ADJUST VALUES lever up or down to set the mix percentage, which ranges from -100% to +100%.A value of “+/- 0 %” means the master channel will have no effect on the slave channel. The “+” and“-“ indicators note the direction in which the master will affect the slave channel (see figure 17C).

7. Check the controls of the airplane and observe how the model responds to be certain you haveachieved the correct mix and that the throws are as desired. Note: Mixing recommendations might beincluded in the airplane’s instruction manual. Press and hold the SCROLL MENU and SELECTCHANNEL buttons to return to the main screen.

“W.MIX” – WING MIXING TYPESThe 6XM’s four “wing” mixes are designed so the master and slave channels are each pre-set. The user simply selects the propermix to fit the aircraft. The four pre-set factory mixes are: “FP” for flaperons, “V” for v-tail, “FPv” for flaperons + v-tail, and “EL” forelevons. Determine the appropriate mix to match your application. Note that when using a mix, reversing the direction of any oneservo in the mix will reverse the direction of that servo but not the other servo in the mix. To reverse both servos in mix, each mustbe reversed separately. Refer to the “Reversing” section on page 12 to achieve the correct direction of servo throws. If there’sdoubt about how to properly set a mix for your airplane, refer to your airplane’s instruction manual or supplier for details. To selecta wing mix:


2. Press the SCROLL MENU button to find the “W.MIX” screen. The first W.MIX screen will also show “FP”, for flaperons. Pressingthe SCROLL MENU button again will step the menu to the other three pre-set mixes, for “V” (v-tail, jump to step 4), “FPv” (flaperons+ v-tail, jump to step 5), and “EL” (elevons, jump to step 6).

3. “FP” – FLAPERON MIXING: Flaperon mixing allows the ailerons to be used both asailerons and as flaps. Here, the ailerons will function like normal with the aileron stick.And, adjusting the flap control dial (CH6) will also move the ailerons so that they functionlike flaps. Note that the use of flaperon mixing means that both of the airplane’s aileronsmust be controlled by separate servos. To set the aircraft for flaperon mixing:

A. Connect the aileron servo in the right wing to receiver channel 1 (aileron), and connect theaileron servo in the left wing to receiver channel 6 (flaps).

B. Move the ADJUST VALUES lever to find the “FP” screen. The flaperon mix will now be on.C. The servo travels will automatically be reduced to 60% and 40%, but full servo throw will still be

achieved when the aileron stick and the flap control dial are moved to their full extremes.D. Jump to step 7 if no other mixing is needed.

4. “V” – V-TAIL MIXING: Some aircraft have a tail section which does not have a perfectly vertical wingor “stabilizer” and perfectly horizontal stabilizer. Rather, the tail has angled surfaces which resemblesa letter “V”. V-tail aircraft (such as a Beechcraft Bonanza) require a radio having a mix that allows thetwo tail surfaces to perform the function of an airplane’s elevator and rudder, or “ruddervator”. Notethat the use of v-tail mixing means that both of the airplane’s tail surfaces must be controlled by aseparate servo. To set the aircraft for v-tail mixing:

A. Connect the left ruddervator servo to the receiver channel 2 (elevator), and connect the rightruddervator servo to receiver channel 4 (rudder).

B. Move the ADJUST VALUES lever to find the “V” screen. The v-tail mix will now be on.C. 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.D. Jump to step 7 if no other mixing is needed.

5. “FPv” – FLAPERONS + V-TAIL: The flaperons + v-tail function is used when both flaperons and v-tail mixing is required. To set the flaperons + v-tail mixing:

A. Connect the left ruddervator servo to receiver channel 2 (elevator), and connect the rightruddervator servo to receiver channel 4 (rudder).

B. Connect the aileron servo in the right wing to receiver channel 1 (aileron), and connect theaileron servo in the left wing to receiver channel 6 (flaps).

C. Move the ADJUST VALUES lever until “FPv” is shown. The flaperon + v-tail mix will now be on.D. Jump to step 7 if no other mixing is needed.

16

Figure 18

Figure 19

Figure 20

6. “EL” – ELEVON MIXING: Elevon mixing is designed for “flying wing” type aircraft which do not have a traditional “tail” section,such as a delta-wing or flying wing airplanes (like the B-2 Stealth Bomber). This feature mixes channel 1 (aileron) and channel 2(elevator) to allow the airplane’s main horizontal control surfaces to function in unison (as elevators), and in opposition (asailerons). Note that the use of elevon mixing means that (a) each of the airplane’s elevons must be operated by a separate servo.To set the aircraft for elevon mixing:

A. Connect the servo in the right wing to receiver channel 2 (elevator), and connect the servo inthe left wing to receiver channel 1 (aileron).

B. Move the ADJUST VALUES lever to find the “EL” screen. The elevon mixing will now be on.C. The servo travels will automatically be reduced to 60%, but full servo throw will still be achieved

when the control stick is moved to the extremes for both servos. (The purpose for this reductionis so that, for example, if applying full up “elevator,” there will still be servo throw “left over” sothe servos can travel yet farther when aileron is simultaneously applied.)

7. Once a mix has been activated, press and hold both the SCROLL MENU and SELECT CHANNELbuttons for 1 second to exit the programming mode.

8. Move the servos to their full extremes to make certain the mixes and servos are functioning properly,and not overdriving the controls. If necessary, re-adjust the servo’s linkages to achieve the correctcontrol throws.

TRAINER SYSTEM

The 6XM includes a trainer function which aids in training students how to fly. CAUTION: Only train with an experienced pilotcontrolling the teacher’s transmitter. You’ll learn faster, and failure to do so could risk personal injury to yourself and others, andrisk damage to your model and other property. If you are unsure of where to locate a flying club in your local area, contact theAcademy of Model Aeronautics (AMA) who can assist you in finding one of their more than 2,300 chartered clubs across thecountry. Most of the clubs provide instructor training programs and insured newcomer training.

http://www.modelaircraft.org/

For training, the 6XM must be linked to another Tx with a “trainer cord” (available separately, see page 20). The 6XM’s trainerfunction is compatible with any Tower Hobbies or Futaba brand FM aircraft radio system which also has a trainer jack. To use thetrainer function:

1. Find a trainer cord having a plug on one end that is compatible with the 6XM’s trainer jack, and having a plug on the oppositeend that is compatible with the trainer jack on the second Tx. The two most common trainer jacks are the small, square “micro”jack (used on most newer Tower Hobbies and Futaba brand radios), and the round “DIN” type jack (used on older model TowerHobbies and Futaba brand radios).

2. The teacher will use the main Tx that is already set up for the airplane. The student will hold the Tx on the opposite end of thetrainer cord

3. If the student’s Tx has PCM/PPM capability, set it to PPM. Allow the teacher to make sure the reversing and trim settings of thestudent’s Tx match that of the teacher’s Tx.

4. Remove the Rf module or crystal from the student’s Tx.

5. Collapse the antenna on the student’s Tx, and fully extend the antenna on the teacher’s Tx.

6. Connect the trainer cord to both Tx’s.

7. Turn on the teacher’s Tx, but DO NOT turn on the student’s Tx. When the trainer cord is connected to the student’s Tx its controlsection will automatically turn on but the Rf section will not emit a signal.

8. Turn on the Rx in the airplane and make sure the teacher’s Tx has control of the surfaces on the aircraft.

TRAINER SYSTEM

17

Figure 21

9. Pull and hold the spring-loaded trainer switch on the teacher’s Tx, and then make sure the student’s Tx has control of thesurfaces on the aircraft. Allow the teacher to make any necessary adjustments to the student’s Tx so that the surfaces on theaircraft are trimmed and respond correctly to the inputs on the student’s Tx. This is to make sure there are no abrupt changes tothe attitude of the airplane when changing between the teacher and student’s Tx’s.

10. During flight, the teacher will pull and hold the trainer switch on his Tx to pass control of the aircraft to the student. The teachercan instantly re-gain full control of the airplane by releasing the trainer switch on his Tx.

Note: There may be a very brief delay from when the teacher moves the trainer switch on his transmitter before the student takescontrol of the aircraft. In most situations this momentary delay will go unnoticed.

Many pilots set up their engine and radio so that the engine runs at idle when the throttle stick is at minimum position, but thethrottle trim is just above minimum. This is often done for the purpose of landing or taxiing the airplane while at idle. But in suchcases a method needs to be available to quickly shut off the engine completely, and the throttle cut function can do this.

To set up the throttle-cut, turn on the Tx and Rx, and move the throttle stick to the full down position. Activate the throttle-cut byrapidly moving the TRAINER / THRO CUT switch two times. When holding the throttle cut switch, notice the momentary positionof the carburetor barrel. If the barrel is completely closed it should kill the engine. If the barrel is NOT completely closed it maybe necessary to adjust the throttle channel’s end point adjustment (see page 14) so that the barrel is closed completely atminimum throttle. It’s important to note that the throttle-cut function works only when the throttle stick is in the down position.

Both control sticks offer the ability to adjust their length. This can be done to customize the Tx to the size of your hands. To adjustthe length of a stick, hold the base of the stick (B) with one hand, and with the other hand rotate the tip of the stick (A) counter-clockwise to loosen it from the base. Rotate the stick base B to lengthen or shorten the length of the stick. Once the proper lengthis found, lock the stick by holding the stick base B, then rotating the stick tip A in a clockwise direction.

The 6XM may be operated in one of four different stick modes” (1, 2, 3, or 4). The “mode” refers to the which sticks control whichof the four main channels on the airplane. The factory default for the 6XM is to operate in mode 2, which is most commonly usedin the U.S.. In mode 2, the right stick controls aileron (side to side) and elevator (up and down), and the left stick controls throttle(up and down) and rudder (side to side).

Mode 1 is the second most common stick mode, where the right stick controls aileron and throttle. The left stick controls elevatorand rudder. Modes 3 and 4 are rarely used, but can be selected if desired.

To change the 6XM’s operational mode, make sure the Tx’s power switch is turned OFF, then simultaneously press and hold theSCROLL MENU and SELECT CHANNEL buttons, then turn the Tx’s power switch ON. A single numerical digit will show on-screen. Move the ADJUST VALUES lever up or down to change the mode. If a mode is selected that moves the throttle controlto the right stick (such as mode 1), the mechanical ratchet for the throttle stick will have to be physically moved from one stick tothe other. This can be done by Hobby Services (see page 21).

Flight preparation should be done at the flying field. If you are an inexperienced pilot, be certain your flight instructor performs thefollowing checks with you.

1. Make sure all batteries are charged.

2. Pull the frequency clip from the frequency control board.

3. Check the airplane before flight. Turn on the Tx, then the Rx. Make sure the Tx is set on the correct model memory to matchthe model you will be flying. Make sure all batteries are charged.

4. Check the operation of all controls, for smooth operation with no binding of any controls or unwanted noise from any servos.

5. Range check the radio.

6. Fully extend the Tx antenna. Never fly without fully extending the Tx antenna, as it will decrease operational signal range of thesystem. Do not point the antenna directly at the model as the transmitter’s weakest signal is emitted directly off the tip of theantenna. The strongest signals from a Tx antenna are emitted at an oblique angle off the side of the antenna.

7. Check the flying site and be aware of obstacles which could obstruct safe flight, such as other modelers, other models, fences,light poles, etc.

Find a suitable flying site. If you are a beginner modeler, it’s highly recommended to become a member of a local R/C club whichhas a designated flying site for R/C model aircraft. It’s also highly recommended to join the AMA (Academy of Model Aeronautics).Membership with the AMA is required to fly at one of the over 2,500 AMA chartered clubs in the U.S. Among other benefits, theAMA provides insurance to its members who fly at sanctioned sites and events. Training programs and instructors are alsoavailable at AMA clubs to help you get started the right way. Contact the AMA at the address or toll-free phone number below:

IMPORTANT: If you do insist on flying alone you must be aware of your proximity to any local R/C club flying sites. If you fly withinsix miles of an R/C club site, and if you fly on the same frequency as someone at the flying site there is a strong possibility thatboth models may crash due to radio interference. An out-of-control model can cause significant property damage and/orsevere personal injury!! Therefore, for safety reasons, it’s highly recommended to fly at an R/C club site.
