INTRODUCTION

Thank you for purchasing the Futaba 6EXHP digital proportional R/C helicopter system. If this is your rst computer radio, rest assured that it is designed to make initial setup and eld-tuning of your helicopter 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 yers in mind, in order to make the best use of your Futaba 6EXHP 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, youll be able to see the effects of your programming inputs.

*Specications and ratings are subject to change without notice
Receiver crystals: The receiver frequency may be changed as long as it remains within the low and high band frequency range. If your receiver is on any channel from 11 through 35, it is a low band receiver and the frequency may be changed to any other channel from 11 through 35 without having to perform any other service. Simply purchase a crystal on the desired channel, then replace the existing crystal in your receiver with the new one. If your receiver is on any channel from 36 through 60, it is a high band receiver and the frequency may be changed to any other channel from 36 through 60. To order a receiver crystal, replace the ** in the order numbers below with the required channel number. (To order a receiver crystal on channel 30, order FUTL5730.) FM Dual Conversion 72 MHz low band (channels 11 - 35) receiver crystal. FUTL57** FM Dual Conversion 72 MHz high band (channels 36 - 60) receiver crystal. FUTL58** Note: Should you ever wish to change the transmitter frequency, the transmitter must be sent to the Futaba Service Center for retuning. 3

INTRODUCTION TO THE 6EXHP SYSTEM
IMPORTANT!: Always turn on the transmitter rst, then the receiver. When turning off the system, always turn off the receiver rst. 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. Dual rate (D/R), Idle up, Throttle hold, and Gyro sense can be operates by switch. Two different gyro senses can be set with Futaba GY401/502/601 Gyro on gyro function of this transmitter. Transmitter controls The diagram and explanations briey describe the functions of the Futaba T6EXHP transmitter. Full instructions on how to operate the controls are provided beginning on page 10. NOTE: The diagram shows a Mode 2 system as supplied. (More on ight modes on page 22).
DESCRIPTIONS: Aileron, Elevator and Rudder dual rate switch Use this switch to ip 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 ips between exponential rates (if used). Throttle hold switch - This switch operates to hold the engine in the idling position and disengaged it from the Throttle Stick. It is commonly use to practice auto-rotation. 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 ne tuning the throttle servo when the engine is at idle. Throttle trim does not affect the throttle servo when the throttle control stick is all the way up (so idle r.p.m. can be adjusted without affecting throttle settings through the rest of the stick movement). 4

Charging jack - Port for charging the transmitter batteries with the included battery charger. On-off switch 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 13 or 14(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. Idle up switch - This switch operates to change the ght condition which is set the throttle curve and pitch curve of mid air maneuvers (rolls, loops, stall turns) and 3D ight. Gyro switch/Channel 5 - You can connect the sense adjust connector to the channel 5 of the receiver to operate the gyro which has two different sense. Also if you use Futaba GY401/502/601 Gyro, two different gyro senses setting on gyro function in this transmitter can be call by this switch. 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. INPORTANT!: Please use PCM receiver if the composition parts of the model used much metal, carbon graphite etc. because they will generates quite a lot of the noise. Make certain the 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. 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 helicopter 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 nd 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. When you install the switch harness to the helicopter, please use switch cover. Generally sandwich the frame by switch and switch cover and securely tighten the screws. It might be different installations on model by model. In that case, please follow the model instruction manual. 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: You may run the antenna inside of a non-metallic housing within the fuselage, but range may suffer if the antenna is located near metal or carbon ber pushrods or cables. Do not bind the antenna with servos, switch, battery harnesses. Be sure to perform a range check before ying (see page 23). External antenna mounting: Please use rubber grommet or silicon tube to protect from cut or peel off insulation of antenna on the fuselage antenna-exiting hole.
Place the receiver antenna out from the fuselage part to the nonmetal tube installed in skid etc. Please keep antenna away from parts that made of metal and carbon graphite.
The receiver contains precision electronic parts. It is the most delicate 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 ts best to the base of the antenna as shown. You may cut off the other end of the clip.

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). REST 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 will appear on the screen. 3. Push DATA INPUT upward or downward for about 2 seconds to clear and reset the memory. CLR blinks rst, 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 and swashplate type settings are 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 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 you are certain you want to clear-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 or 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 is displayed. To select PPM modulation, push the DATA INPUT lever down. The 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 ying 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. Push SELECT key three times after seeing on the screen the model memory where you want to set the model name, then you will see the model name on the screen. 3. Choose a character for the rst 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 or switch). After using the reversing function, check all the controls on the model to be certain they are operating in the correct direction and that you did not inadvertently reverse a servo other than the one intended. Reversing the wrong servo (and not checking the response of the controls before each ight) 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 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). 4. Use the SELECT key to display other channels to be reversed.
Dual Rates / Exponential Settings The aileron, elevator and rudder dual rates on the 6EXHP 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 setting the dual rates. When setting the E.P.A.s for the rst time on a new model, the dual rates should be set to 100%.

N-TH Normal throttle curve function Used to set throttle curve for normal ight. 5-point throttle curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine. Throttle curve can be adjust from 0-100% each point. This normal throttle curve create basic curve for around hovering. Use this function together with the normal pitch curve (see Normal pitch curve) so that up/down control has a constant engine speed. To set the normal throttle curve: 1. Enter the programming mode and use the MODE key to access the N-TH function. Throttle stick position number will appears on left side of display and % symbol will be ashing. 2. Use SELECT key to select the desire curve point. Point 1 is shown initially which is throttle stick all the way downward (slow) position. Point 5 is throttle stick all the way upward (hi) position. 3. Push up or down DATA INPUT lever to set the servo position. 4. Use SELECT key to set other points with same manner.
N-PI Normal pitch curve function Used to set pitch curve for normal ight. 5-point pitch curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine. Pitch curve can be adjust from 0-100% each point. This normal pitch curve create basic curve for around hovering. Use this function together with the normal throttle curve so that up/down control has a constant engine speed. To set the normal pitch curve: 1. Enter the programming mode and use the MODE key to access the N-PI function. Throttle stick position number will appears on left side of display and % symbol will be ashing. 2. Use SELECT key to select the desire curve point. Point 1 is shown initially which is throttle stick all the way downward (slow) position. Point 5 is throttle stick all the way upward (hi) position. 3. Push up or down DATA INPUT lever to set the servo position. 4. Use SELECT key to set other points with same manner.
I-TH Idle-up throttle curve function Used to set throttle curve for idle up ight. 5-point throttle curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine when idle up function is on. Throttle curve can be adjust from 0-100% each point. This idle up throttle curve is to set for consistent engine RPM and can be activated at any time when mid air maneuvers are executed, such as loops, rolls, and 3D ight even when reduced the blade collective pitch. To set the idle-up throttle curve: 1. Enter the programming mode and use the MODE key to access the I-TH function.
2. Push the DATA INPUT lever upward. This will cause the ashing INH display to change to a ashing ON display. Now the I-TH function is on. Push the SELECT key, throttle stick position number will appears on left side of display and % is blinks.
3. Use SELECT key to select the desire curve point. Point 1 is shown initially which is throttles stick all the way downward (slow) position. Point 5 is throttles stick all the way upward (hi) position. 4. Push up or down DATA INPUT lever to set the servo position. 5. Use SELECT key to set other points with same manner.

I-PI Idle-up pitch curve function: Used to set pitch curve for idle up ight. 5-point pitch curve is utilized to best match the blade collective pitch to the consistent engine RPM when idle up is used. Pitch curve can be adjust from 0-100% each point. The high side pitch curve should be set to not to over load the engine and keep consistent engine RPM. Generally set less pitch than normal maximum pitch. The low side pitch curve is to set for desired maneuver such as loops, rolls, and 3D ight. To set the idle-up pitch curve: 1. Enter the programming mode and use the MODE key to access the I-PI function. 2. Push the DATA INPUT lever upward. This will cause the ashing INH display to change to a ashing ON display. Now the I-TH function is on. Throttle stick position number will appears on left side of display and % symbol will be ashing. This function cannot be used when I-TH function is not activated. When you set I-PI function, you mast activates I-TH function.
HOLD Throttle hold function Throttle hold function is to be used for autorotations where only pitch control is used to make a descent and landing. Just ip the hold switch on to set the engine in the idling or cut position and disengaged it from the Throttle Stick. It can be set from (-)50 to (+)50% from throttle trim position. To set the throttle hold: 1. Enter the programming mode and use the MODE key to access the HOLD function.
2. Push the DATA INPUT lever upward. This will cause the ashing INH display to change to a ashing ON display. Now the HOLD function is on.
3. Push SELECT key once. This will cause the ashing % symbol on the display. Pull the hold switch fowards you. Push up or down DATA INPUT lever to set the throttle servo position of throttle hold.
REVO Pitch-rudder mixing function This mix adds rudder in conjunction with pitch. This helps compensate for rotation of the helicopter caused by the increased engine torque. (Never use revo. mixing with a heading-hold/AVCS gyro which is in heading hold/AVCS mode. However, revo. mixing is still used when a heading-hold/AVCS gyro is in normal mode.) To set the REVO mixing: 1. Enter the programming mode and use the MODE key to access the REVO function.
2. Push the DATA INPUT lever upward. This will cause the ashing INH display to change to a ashing ON display. Now the REVO function is on.
3. Push the SELECT key once. This will cause the ashing % symbol on the display. It can be set mixing amount on throttle stick hi side and low side separately. When you move the throttle stick to the low side from neutral, the arrow indicates down direction and than push up or down DATA INPUT lever to set the mixing amount of the low side. When you move the throttle stick to the high side from neutral, the arrow indicates up direction and than push up or down DATA INPUT lever to set the mixing amount of the low side.

GYRO Gyro mixing function GYROS : Using electronics to take some of the complexity out of setups and ight. What is a gyro? A gyroscope is an electronic unit that senses motion and corrects for it. For example, if the wind blows your helicopters tail to the left, a gyro will sense that motion (and conrm that no input was given) and will correct for it. How does it help in helicopter setup? A good gyro will totally eliminate the need for revo. mixing. The gyro will sense and correct the unwanted motion for you, so you don t have to spend time to get a complex curve operating properly.
Gyro sensor kinds: There are many different kinds of gyros. Early gyros were mechanical, with a spinning drum similar to a childs gyroscope toy. The next generation utilized a special type of crystal, called piezoelectric, which sensed the motion and provided an electrical pulse. The nest gyros at the time of this writing are SMM technology. These silicone micro machines, or computer chips, sense the motion. SMM is far more accurate and less susceptible to inaccuracies caused by temperature changes, etc. Choosing the right gyro for your skills, your helicopter, and your budget: Mechanical: some are still available. They are very challenging to set up and not as reliable as piezo or SMM. Non-Heading-Hold Piezo: these are now inexpensive gyros that are reliable and easy to set up. Some have dual rates and remote gain control to adjust sensitivity in ight. Lack heading-hold capabilities for precision ying. Heading-Hold Piezo: Until recently, the cream of the crop. Expensive, and more complex to set up. Adds GPS-like heading recognition. Exhibits minor difculties with temperature drift (position setting varying with units temperature).
Heading-Hold SMM: 21st Century gyro technology. Computer chip technology. Expensive, easier set up, higher durability. Signicant decrease in temperature sensitivity. Many include frame rate settings to allow faster response when using specialized digital servos. Examples: GY401: Simpler set up. Ideal for learning aerobatics through 3D. GY502: Better centering than 401 for more advanced aerobatics. Ideal through Class III competition. GY601: Exceptional center. Extremely fast response time. Requires specialized servo. Gyro mixing function is use for adjusting the gain of the gyro and selecting the gain from two different gain settings by switch on the transmitter with the gyro that can set two different gains witch placed on the model. To set the GYRO mixing: 1. Plug the gyros sensitivity adjustment to channel 5 of the receiver. (not assignable) 2. EPA of channel 5 (see page 12-13) to set 100% both UP and DOWN. 3. Enter the programming mode and use the MODE key to access the GYRO function.

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 doesnt 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 theres interference. This may give enough warning to allow you to y 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 havent 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 youll 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 screen with the MODE key. 2. You can nd 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 function works and press DATA INPUT lever downward for about two seconds while holding the stick. A gure in percentage will be shown with a beeping sound. Press DATA INPUT lever upward if you want to set NOR. The arrow moves to NOR side and then this channel will be set to 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 6EXHP FUNCTIONS

Trainer function (student only) The T6EXHP trainer function lets you practice flying as student by connecting the T6EXHP to the instructors Futaba transmitter. When two radios are connected with the trainer cord, they are both capable of operating the model, but its usually best for the instructor to hold the radio that has been setup for the plane to be own (as it is already programmed to y 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 6EXHP to the T7CHP, T9CHP or 14MZ with the small, square micro trainer jack, use the Micro to Micro (MM-TC) trainer cord (FUTM4415). If connecting the 6EXHP to Futaba radios with the larger, round, DIN connector, use Micro to DIN (MD-TC) trainer cord (FUTM4420). Corresponding types of transmitters for helicopter: T6X,T7U,T7C,T8U,T9C,T9Z,T14MZ To use the trainer function: 1. It is best for the instructor to use the transmitter that is already set up for the model to be own. 2. Set your T6EXHP (student s radio) to the follow modulation mode; If the instructor uses the T7C,T8U,T9C,T9Z or T14MZ, set your radio to PPM. If other Futaba radio, set the mode of your radio to match the mode of the instructors.
3. Collapse the students antenna and fully extend the instructors antenna. 4. With the transmitters off, connect the trainer cord to both radios. (On the 6EXHP 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. 5. Turn on the instructors transmitter. 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 students radio to match that of the instructors. 6. Turn on the receiver switch in the model. Depress the trainer switch on the instructors radio. Use the students radio to operate the controls (ailerons, elevator, rudder, etc.) and observe how they respond. Make any adjustments necessary to the students transmitter to get the controls to respond correctly. 7. 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 students radio do not match those on the instructors radio. Adjust the students trims as necessary. 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). Throttle-cut works only when the throttle stick is down. To set up throttlecut, 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. Adjustable-length control sticks The control stick length is adjustable to make the transmitter more comfortable to hold and operate. To adjust the length, hold the locking piece (B) and turn the stick tip (A) counterclockwise. Turn the locking piece B up or down to lengthen or shorten the stick. When the length is suitable, lock the stick in position by turning locking piece B counterclockwise.

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 6EX-2.4GHz the dual rate switch allows you to instantly switch, in ight, between two different control throws for the aileron, elevator and rudder. Often, different control throws are required for different types of ying. (Low throws may be required for ying at high speeds where the models response becomes more sensitive, and high throws may be required for aggressive aerobatic maneuvers or landing or ying 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 ying airplane. (Dual rates adjust the amount of servo travel. Exponentials determine 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 servos end points can be independently set.

RADIO INSTALLATION

Follow these guidelines to properly mount the servos, receiver and battery. Make certain the 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. Do not over Servo tighten the screws. No part of the servo casing should contact the mounting rails, servo tray or any other part of the airplane/helicopter structure. Otherwise, vibration will be transmitted to the servo causing premature wear and/or servo failure.

Rubber grommet

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 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 wont 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 of the switch in both directions. When you install the switch harness to the helicopter, please use the switch cover. Generally sandwich the frame by switch and switch cover and securely tighten the screws. Different models might require different installations. In that case, please follow the model instruction manual. To prevent the servo lead wires from being broken by vibration during ight, provide a margin so that the wire sticks out slightly and fasten it at suitable points. In addition, periodically check the wire during daily maintenance.

Fasten about 5-10cm from the servo outlet so that the lead wire is neat.

Margin in the lead wire.

IMPORTANT: Since the 2.4GHz have different characteristics than that of the conventional 27MHz and 72MHz frequencies, please read this section carefully to enjoy safe ight with the 2.4GHz system.
Receiver's Antenna Installation: The R606FS has two antennas. These antennas have a diversity function to decrease the chance of a receiving error. Since the wavelength of the 2.4GHz is much shorter than that of the conventional frequencies 27MHz and 72MHz, it is very susceptible to loss of signal which results in a receiving error. In order to avoid this phenomenon, the R606FS adopted a diversity antenna system.

Antenna Coaxial cable

*Must be kept as straight as possible.

R606FS Receiver

To obtain the best results of the diversity function, please refer to the following instructions; 1. The two antennas must be kept as straight as possible. Otherwise it will reduce the effective range. 2. The two antennas should be placed at 90 degrees to each other. This is not a critical gure, but the most important thing is to keep the antennas away from each other as much as possible. Larger models can have large metal objects that can attenuate the RF signal. In this case the antennas should be placed at both sides of the model. Then the best RF signal condition is obtained at any ying attitude. 3. The antennas must be kept away from conductive materials, such as metal and carbon by at least a half inch. The coaxial part of the antennas does not need to follow these guidelines, but do not bend it in a small radius. 4. Keep the antennas away from the motor, ESC, and other noise sources as much as possible.

Antenna

*The two antennas should be placed at 90 degrees to each other. *The main purpose of the photo demonstrates how the antenna should be placed. For actual installation the receiver must be wrapped with a sponge or placed with floating material to protect it from vibration.

Link Procedure Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no further linking is necessary unless the receiver is to be used with another transmitter. (For T/R set, the link is already done at factory. When you purchased another R606FS, this procedure is necessary; otherwise the receiver will not work. 1. Place the transmitter and the receiver close to each other within one (1) meter 2. Turn on the transmitter. 3. Check the LED that is placed on the back side of the transmitter to see if the RF signal is active. When the green LED is ON solid, the RF signal is being sent. 4. Turn on the receiver. 5. Press down the "ID SET" switch for more than one second, and release the switch. The receiver starts the linking operation. 6. When the linking is complete, the LED in the receiver will change to solid green. Please conrm that the servos will now operate by your transmitter. Please refer to the table below for the LED status of the receiver's condition.
No signal reception Receiving signals Receiving signals, but ID is unmatched. Unrecoverable failure (EEPROM, etc.) Red : On Green: On Green: Blink Red and Green turn on alternately.

CHARGING THE NiCd BATTERIES
The transmitter batteries included with your 6EX-2.4GHz system are rechargeable, NiCd (nickel-cadmium, pronounced nikad) batteries. NiCd batteries require special care and charging. Read the charging instructions carefully. NOTE: The batteries are supplied partially charged, but will require a full, overnight charge before the model may be own. 1. Connect the transmitter charging cord coming from the A/C wall charger to the charge jack in the right side of the transmitter case. The receiver charging cord may be connected to the batteries two different ways: The charge cord may be connected directly to the battery pack, or to the vacant charge connector (black) coming from the on/off switch in the model. Charging through the switch is preferred as there will be no need to disconnect the battery. 2. Plug the A/C wall charger into a wall outlet. Note: If the wall outlet can be turned off by a switch in the room, be certain the switch remains on after leaving the room. Otherwise, the batteries will not be charged! 3. The LEDs (light-emitting diodes) should light red, indicating that current is owing and the batteries are being charged. Discharged batteries will take about 15 hours to fully charge. If using an aftermarket fast charger, be certain to follow the manufacturers instructions provided with the charger so you do not overcharge the batteries. NEVER charge the batteries at a rate higher than 1,000mAh. The batteries should also be discharged periodically to prevent a condition called memory. If, for example, only two ights are made each time you go ying, 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 ights. After two ights 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.

Transmitter battery voltage In addition to the model type, the LCD screen also displays the transmitter battery voltage. When the voltage goes below approximately 8.5 Volts the battery icon will ash and the lowbattery alarm will continuously beep until the transmitter is turned off. When the low-battery alarm sounds, land immediately your model before losing control.

Battery icon

Note: If the transmitter ever reaches 8.9 Volts, land as soon as safely possible. A more reasonable margin of safety would be to quit ying for the day (or recharge the batteries) when the transmitter battery reaches 9.4 Volts.
SUGGESTED GUIDELINES 9.4 Volts - No more ying until recharge. 8.9 Volts - Land as soon as safely possible. 8.5 Volts - Emergency- Land immediately!
Mixer alert warning (HELI only) If the transmitter is turned on with the throttle hold or idle up function switched on, the screen will show "MIX" and a warning will sound. Please turn the throttle hold and idle up functions off to precede.
Backup error The Backup error warning occurs when the transmitter memory is lost for any reason. If this occurs, all of the data will be reset when the power is turned on again. When the Backup error occurs, initialization starts from model number 6 to 1. The model number on the left of the screen changes from 6 to 5, to 4, to 3, to 2, to 1, and finally the number disappears. The disappearance of the model number indicates that the initialization has been completed. Now you can turn off the power of the transmitter. Please do NOT turn off the power during the initialization; otherwise initialization will restart when you turn on the power. Do not fly when this message is displayed: all programming has been erased and is not available. Return your transmitter to Futaba service.
PROGRAMMING THE 6EX-2.4GHz RADIO
Anytime you wish to view or change any of the current settings in the transmitter, the programming mode must first be entered by, of course, turning on the power, then by pressing the MODE and SELECT keys simultaneously and holding them down for one second. Once in the program the MODE key will be used to scroll through each of the functions (Model type ACRO: model select/ data reset/ model type select/ modulation select/ trainer/ model name, reversing, dual rates/ exponentials, end point adjustments, trim, programmable mix 1, programmable mix 2, aperon mixing, ap trim, v-tail mixing, elevon mixing, and failsafe Model type HELI: model select/ data reset/ model type select/ modulation select/ model name, reversing, dual rates/ exponentials, end point adjustments, trim, normal throttle curve, normal pitch curve, idle-up throttle curve, idle-up pitch curve, throttle hold, revolution mixing, gyro sensitivity, swash-throttle mixing/ swashplate types, 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 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 name and battery voltage is displayed) by pressing the MODE and SELECT keys simultaneously and holding them down for one second. Note: The functions are listed and described in the order that they appear in the transmitter. Read all the way through the programming instructions before setting up your model (if you wont be using any of the mixing functions for a while you can read those instructions when ready). Refer to the FLOW CHART on page 31(ACRO) or page 32(HELI) as well.

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 ight, to get the model properly trimmed (so it will y straight-and-level). Because the trims are intended to be used while the model is in ight, you do not have to enter the program to adjust the trims. Simply push or pull on the trim levers while ying 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 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 8). 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 nal 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 y 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 servos 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.
PMIX1/2 Programmable Mixer 1/2 (ACRO only) Unlike the wing mixing function (explained later) where the channels to be mixed are factory-set, the T6EX-2.4GHz also contains two programmable mix where you, the pilot determine the channels to be mixed. This could be used to correct unwanted ight 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 screen with the MODE key.

2. Push the DATA INPUT lever upward for 0.5 seconds. This will cause the flashing INH display to change to a ashing ON display.
3. Push SELECT key twice to call the screen for selecting channels to control MAS (Master) mixing. Then select the channel by pushing DATA INPUT lever. Channel 1 (aileron) in this gure is assigned to the master.
4. Push SELECT key once to call the screen for selecting channels to control SLV (Slave) mixing. Then select the channel by pushing DATA INPUT lever. Channel 4 (rudder) in this gure is assigned to the slave.
5. Press the SELECT key three times 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. Push SELECT key to call the screen for selecting the on/off switch. Then select the switch by pushing DATA INPUT lever. CH5, D/R, or FLP switch (include the on direction) is selectable. The ON is always on.
7. 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 (ACRO only) 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 (ACRO only) This function allows the ailerons to be used both as ailerons and as flaps. The ap control switch (CH 6) operates the ap function. To use aperon mixing both ailerons must be operated by separate servos.
*If necessary, use the Servo Reversing function to achieve the correct direction of servo throws.
To activate aperon 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 (aps) in the receiver.
2. Enter the programming mode. Access the FLPR screen with the MODE key.
You cannot set Flaperon mixing when Elevon mixing has already been set. In order to enable Flaperon mixing, you rst need to cancel Elevon mixing. However, it is allowed to use Flaperon and V-Tail mixing simultaneously.
3. Push the DATA INPUT lever upward for 0.5 seconds. This will cause the flashing INH display to change to a ashing ON display. Now the mixing is on.

ELVN Elevon mixing (ACRO only) Intended for tailless, ying wing models such as delta wings and ying 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 screen with the MODE key.
You cannot set Elevon mixing when Flaperon or V-TL mixing has already been set. In order to enable Elevon mixing, you rst need to cancel both Flaperon and V-tail mixing.
4. Next you set the left wing to channel 1 (aileron) setting. Press the SELECT key to display the CH1 and ashing % 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 ashing % sign. Use the DATA INPUT lever to set the percentage of rudder travel rate from -100% to +100%
N-TH Normal throttle curve function (HELI only) Used to set throttle curve for normal ight. 5-point throttle curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine. Throttle curve can be adjusted from 0-100% each point. This normal throttle curve creates a basic curve for hovering. Use this function together with the normal pitch curve (see Normal pitch curve) so that up/down control has a constant engine speed. To set the normal throttle curve: 1. Enter the programming mode and use the MODE key to access the N-TH function. Throttle stick position number will appear on left side of display and % symbol will be ashing. 2. Use SELECT key to select the desire curve point. Point 1 is shown initially which is throttle stick all the way downward (slow) position. Point 5 is throttle stick all the way upward (hi) position. 3. Push up or down DATA INPUT lever to set the servo position. 4. Use SELECT key to set other points in same manner.
N-PI Normal pitch curve function (HELI only) Used to set pitch curve for normal ight. 5-point pitch curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine. Pitch curve can be adjusted from 0-100% each point. This normal pitch curve creates a basic curve for hovering. Use this function together with the normal throttle curve so that up/ down control has a constant engine speed. To set the normal pitch curve: 1. Enter the programming mode and use the MODE key to access the N-PI function. Throttle stick position number will appear on left side of the display and % symbol will be ashing. 2. Use SELECT key to select the desired curve point. Point 1 is shown initially, which is throttle stick all the way downward (slow) position. Point 5 is throttle stick all the way upward (hi) position. 3. Push up or down DATA INPUT lever to set the servo position. 4. Use SELECT key to set other points with same manner.

I-TH Idle-up throttle curve function (HELI only) Used to set throttle curve for idle up ight. 5-point throttle curve is utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine when idle up function is on. Throttle curve can be adjusted from 0-100% each point. This idle up throttle curve is to set consistent engine RPM and can be activated at any time when mid air maneuvers are executed, such as loops, rolls, and 3D ight, even when the blade collective pitch is reduced. To set the idle-up throttle curve: 1. Enter the programming mode and use the MODE key to access the I-TH function.
2. Push the DATA INPUT lever upward for 0.5 seconds. This will cause the flashing INH display to change to a ashing OFF or ON display. Now the I-TH function is on. Push the SELECT key, and throttle stick position number appears on left side of display and % blinks. (OFF: if the idle-up switch is off, ON: if the idle-up switch is on.)
3. Use SELECT key to select the desired curve point. Point 1 is shown initially which is throttle sticks all the way downward (slow) position. Point 5 is throttle sticks all the way upward (hi) position. 4. Push up or down DATA INPUT lever to set the servo position. 5. Use SELECT key to set other points in same manner.
I-PI Idle-up pitch curve function: (HELI only) Used to set pitch curve for idle up ight. 5-point pitch curve is utilized to best match the blade collective pitch to the consistent engine RPM when idle up is used. Pitch curve can be adjust from 0-100% each point. The high side pitch curve should be set to not overload the engine and keep consistent engine RPM. Generally, set less pitch than normal maximum pitch. The low side pitch curve should be set for desired maneuvers such as loops, rolls, and 3D ight. To set the idle-up pitch curve: 1. Enter the programming mode and use the MODE key to access the I-PI function.
2. This is the idle up pitch curve, to use this function the I-TH Idleup throttle function must be activated rst.
3. Use SELECT key to select the desire curve point. Point 1 is shown initially, which is the throttle sticks all the way downward (slow) position. Point 5 is the throttle sticks all the way upward (hi) position. 4. Push up or down DATA INPUT lever to set the servo position. 5. Use SELECT key to set other points in same manner.
HOLD Throttle hold function (HELI only) Throttle hold function is to be used for autorotations where only pitch control is used to make a descent and landing. Just ip the hold switch on to set the engine in the idling or cut position and disengage it from the Throttle Stick. It can be set from (-)50 to (+)50% from throttle trim position. To set the throttle hold: 1. Enter the programming mode and use the MODE key to access the HOLD function.

specialized digital servos. Examples: GY401: Simpler set up. Ideal for learning aerobatics through 3D. GY502: Better centering than 401 for more advanced aerobatics. Ideal through Class III competition. GY611: Exceptional center. Extremely fast response time. Requires specialized servo. Gyro mixing function is used for adjusting the gain of the gyro. Select from two different gain settings using a switch on the transmitter. To set the GYRO mixing: 1. Plug the gyros sensitivity adjustment to channel 5 of the receiver. (not assignable) 2. EPA of channel 5 (see page 12-13) to set 100% both UP and DOWN. 3. Enter the programming mode and use the MODE key to access the GYRO function.
4. Push the DATA INPUT lever upward for 0.5 seconds. This will cause the flashing INH display to change to a ashing ON display. Now the mixing is on.
5. Push the SELECT key once. This will show the gyro gain setting and ashing % symbol on the display.
Flip the gyro (CH5) switch up and down. This will cause the arrow on the display to point up and down corresponding to the switch position. Push up or down DATA INPUT lever to set the gyro gains for both switch up and down position. Gyro gain can be adjust from -100% to +100%.

SW-T Swash to throttle mixing (HELI only) This function corrects slowing of engine speed caused by swashplate operation at aileron or elevator operation. To activate swash to throttle mixing: 1. Enter the programming mode. Access the SW-T screen with the MODE key.
2. Push the DATA INPUT lever upward for 0.5 seconds. This will cause the flashing INH display to change to a ashing ON display. Now the mixing is on. NOTE: The throttle to swash mixing function only operates in the Idle up ight mode.
3. Press the SELECT key to display the CHA. Use the DATA INPUT lever to set the percentage of aileron to throttle mixing rate from 0% to 50%.
4. Press the SELECT key to display the CHE. Use the DATA INPUT lever to set the percentage of elevator to throttle mixing rate from 0% to 50%.
SWSH Swashplate types selection & Swash AFR (HELI only) This function can select from three swashplate types. Swash AFR can be set, if you choose 3-S or 3-E type 1-S: Independent aileron, pitch and elevator servos linked to the swashplate. Most kits are 1-S type.
