Mode 2 transmitter with rear cover removed.
You may adjust the tension of your sticks to provide the feel that you prefer for flying. To adjust your springs, youll have to remove the rear case of the transmitter. First, remove the battery cover on the rear of the transmitter. Next, unplug the battery wire and remove the battery from the transmitter. Next, using a screwdriver, remove the four screws that hold the transmitters rear cover in position, and put them in a safe place. Gently ease off the transmitters rear cover. Now you'll see the view shown in the figure above. Using a small Phillips screwdriver, rotate the adjusting screw for each stick for the desired spring tension. The tension increases when the adjusting screw is turned clockwise. When you are satisfied with the spring tensions, reattach the transmitter's rear cover. Check that the upper printed circuit board is on its locating pins. When the cover is properly in place, reinstall and tighten the four screws. Reinstall the battery cover. Adjusting Display Contrast To adjust the display contrast, from the home menu press and hold the End button. Turn the dial while still holding End button: clockwise to brighten counterclockwise to darken the display Let go off the dial and the button. Changing Modes: Hold down the Mode and End buttons while turning on the transmitter. The screen reads "STK-MD". Change this to the correct mode. Note that this will NOT change the throttle and elevator rachets, etc. Those are mechanical changes that must be done by a service center.

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 tighten the Servo 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.

3. If everything operates correctly, return to the model. Set the transmitter in a safe, yet accessible location so it will be within reach after starting the engine. Be certain the throttle stick is all the way down, then start the engine. Perform another range check with your assistant holding the plane and the engine running at various speeds. If the servos jitter or move inadvertently, there may be a problem. Do not y the plane! Look for loose servo connections or binding pushrods. Also be certain that the battery has been fully charged. 4. The "Power Down Mode" continues for 90 seconds and after that the power will go back to the normal level. To exit the "Power Down Mode" before the 90 seconds, press the Dial again. This mode is available 1 time only so if you need to re-use this function the transmitter power must be cycled. 5. NEVER start ying when the "Power Down Mode" is active.
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. When you purchase another R617FS, 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 "Easy Link(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 con m 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.
TRANSMITTER DISPLAYS & BUTTONS When you first turn on your transmitter, a confirmation double beep sounds, and the screen shown below appears. Before flying, or even starting the engine, be sure that the model type and name appearing on the display matches the model that you are about to fly! If you are in the wrong model memory, servos may be reversed, and travels and trims will be wrong, leading to an immediate crash.

A QUICK GUIDE: GETTING STARTED WITH A BASIC 4-CHANNEL AIRCRAFT This guide is intended to help you get acquainted with the radio, to give you a jump start on using your new radio, and to give you some ideas and direction in how to do even more than you may have already considered. It follows our basic format of all programming pages: a big picture overview of what we accomplish; a "by name" description of what we're doing to help acquaint you with the radio; then a step-by-step instruction to leave out the mystery when setting up your model. For additional details on each function, see that function's section in this manual. The page numbers are indicated in the goals column as a convenience to you. See p.22 for a legend of symbols used. GOALS of EXAMPLE Prepare your aircraft. STEPS INPUTS for EXAMPLE Install all servos, switches, receivers per your model's instructions.

A LOOK AT THE RADIO'S FUNCTIONS STEP BY STEP MODEL submenu: includes three functions that manage model memory: MODEL SELECT, MODEL COPY and MODEL NAME. Since these functions are all related, and are all basic features used with most models, they are together in the MODEL submenu of the BASIC menu.
MODEL SELECT: This function selects which of the 10 model memories in the transmitter to set up or fly. (Each model memory may be of a different model type from the other memories.)

GOAL: Select Model #3.

NOTE: When you COPY one model memory over another, everything is copied, including the model's name. Similarly, if you change MODEL TYPE or do a MODEL RESET, the entire memory is reset, including MODEL NAME. So the first thing you will want to do after you COPY a model, change its type, or start from scratch, is rename the new copy to avoid confusion.
GOAL of EXAMPLE: Name model 3 "CAP-01" (where the underline represents a blank space.)
STEPS: Open MODEL submenu.
INPUTS: for 1 second. (If ADVANCE, to MODEL.
Confirm you are currently using the proper model memory. (Ex: 3) Go to NAME and change the first character. (Ex: M to C) Choose the next character to change. Repeat the prior steps to complete naming the model. Close. Where next?
If SELECT does not indicate 3, perform MODEL SELECT, p. 25. to C.

Change the MODEL TYPE to helicopter: see p. 28. Utilize servo REVERSE : see p. 30. Adjust servo travel with END POINT : see p. 31. Set up dual/triple rates and exponential (D/R,EXP): see p. 33.
PARAMETER submenu: sets those parameters you would likely set once, and then not disturb again. Once you have selected the correct model you wish to work with, the next step is setting up the proper parameters for this specific model:
What is the model's type? Assign the desired SW to CH5 and CH7.
First it is important to clear out any old settings in the memory from prior use, using the MODEL RESET. MODEL RESET: completely resets all data in the individual model you have currently selected. Don't worry - there is no way you can accidentally delete all models in your radio with this function. Only a service center can completely reset your radio's entire memory at once. To delete each model in your radio's memory (for example when selling), you must SELECT each model, reset that memory, then go SELECT the next memory, etc. Note that when you COPY one model memory into another or change the model's type, you need not delete all existing data first by using this function. COPY completely overwrites anything in the existing model memory, including MODEL NAME. The MODEL TYPE function overwrites all data except name.

Exponential: Changes the response curve of the servos relative to the stick position to make flying more pleasant. You can make the servo movement less or more sensitive around neutral for rudder, aileron, elevator, and throttle (except HELI type - use THROTTLE CURVE instead). Why use expo? Many models require a large amount of travel to perform their best tricks. However, without exponential, they are touchy around neutral, making them unpleasant to fly and making small corrections very difficult. Additionally, by setting different exponentials for each rate, you can make the effectiveness of small corrections similar in each rate, as in our example below. The best way to understand exponential is to try it: Having made no changes yet in the D/R,EXP screen, move SWITCH D to "down" (toward the AILERON STICK). Cursor down to EXPand dial to 100%. Move SWITCH D up. Hold the AILERON STICK at 1/4 stick and move SWITCH D down. Notice how much less travel there is. Go to 3/4 stick and repeat. Notice how the travel is much closer, if not identical.

Adjustability:

More sensitive around neutral. (positive exponential, see example) Less sensitive around neutral. (negative exponential, see example)
For ACRO throttle, exponential is applied at the low end to help nitro and gasoline engines have a linear throttle response, so that each 1/4 stick increases engine RPM 25% of the available range. (In most engines this ranges from 5-60%.)
GOAL of EXAMPLE: Set up dual rates and exponential in ACRO mode.

STEPS: Open D/R,EXP.

INPUTS: for 1 second. (If ADVANCE, to D/R,EXP.
Choose channel and switch position. Set rate (Ex: high rate = 95%) Set expo (Ex: expo = -15%) Go to 2 switch position and set rate (Ex: low rate 70%)

Set 2 nd expo (Ex: expo = -3%) Optional: if using a 3 position switch, set 3rd rate. Close.
GOAL of EXAMPLE: Set up dual rates and exponential in HELI mode. Note: In HELI mode the switch does not change the rate being adjusted. Change switch channel and switch position with mode button.

Options: 5-channel receiver. Set up AIL-2 (see p. 42) in FLAPERON. FLAPERON: Uses CH6 for the second servo (see AIL-2 to use CH5 orCH7.) Allows flap action as well as aileron action from the ailerons. Provides FLAP-TRIM function to adjust the neutral point of the flaperons for level flight. Also allows aileron differential in its own programming.
Channel 6 = normal flaperons, 2 servos operate together as flaps; Channel 5 or 7 = act like aileron differential did in prior radios; channel 6 is still FLAPS, and the 2 ailerons never act together as flaps EXCEPT in the airbrake function.
NOTE: Only one of the two wing-type functions (FLAPERON and ELEVON) can be used at a time. Both functions cannot be activated simultaneously. To activate a different wing type, the first must be inhibited. GOAL of EXAMPLE: De-activate FLAPERON so that ELEVON can be activated. STEPS: Open the FLAPERON function. INPUTS: for 1 second.(If basic, to FLAPERON. Inhibit the function. Close function. Where next? Set up ELEVON (see p. 44). to INH.

Using FLAPERON (ACRO):

The FLAPERON mixing function uses one servo on each of the two ailerons, and uses them for both aileron and flap function. For flap effect, the ailerons raise/lower simultaneously. Of course, aileron function (moving in opposite directions) is also performed.
Once FLAPERON is activated, any time you program CH6 or "Flap" (ie. FLAP-ELEVATOR mixing), the radio commands both servos to operate as flaps. A trimming feature is also available (see FLAP-TRIM) to adjust both neutral positions together for straight-and-level flight or slight increases/decreases of the flap angle. END POINT and SUB-TRIM both still adjust each servo individually. Second aileron servo (AIL-2): The default for the second aileron servo is CH6 and this allows both servos to work as ailerons and flaps. If CH5 or CH7 is selected the flap function only works CH6, and the two aileron servos function only as ailerons except in the air brake (A. BRAKE) function. In the air brake function the flap servo CH6 and the aileron servos CH1 and (CH5 or CH7) work together.
GOAL of EXAMPLE: Activate twin aileron servos, FLAPERON. Input 10% more up travel than down travel (aileron differential) within the FLAPERON programming.
STEPS: Open the FLAPERON function.
INPUTS: for 1 second. (If basic, * to FLAPERON.
Activate the function. Optional: adjust the aileron differential.(Ex: +10%) Optional: If using a 5 channel receiver, change AIL-2 from CH6 to CH5. Close menu. to +10%.

*If the FLAPERON function does not activate there is a conflicting mix activated such as ELEVON.
FLAP-TRIM allows the flap action to be set in a way that it can be adjusted with the VR dial. AIRBRAKE will also move the flaps to a specified position via movement of a switch. The flaps can also be moved with switch using a programmable mix. See offset as master p.53.

Add FLAP-TRIM to allow the model's ailerons to drop 30% together as flaps from the VR dial.

There are 4 basic tail types in aircraft models: Simple. Model uses one elevator servo and one rudder servo (or multiple servos on a Y-harness). This is the default. Dual Elevator servos. Model uses 2 elevator servos, see AILVATOR(ACRO.) see p. 45. Tail-less model. Model uses 2 wing servos together to create roll and pitch control. see ELEVON. see p. 44. V-TAIL. Model uses 2 surfaces, at an angle, together to create yaw and pitch control. see V-TAIL. see p. 46. Note: Only one of the three tail-type functions (AILVATOR, V-TAIL, and ELEVON) can be used at a time. (See the wing type example on page 41.)
Using ELEVON(ACRO ): Used with delta wings, flying wings, and other tailless aircraft that combine aileron and elevator functions, using two servos, one on each elevon. The aileron/elevator travel can be adjusted independently. This is also popular for ground model use, such as tanks, which drive two motors together for forward, and one motor forward/one backward for turning. Also aileron differential can be adjusted in this programming.
Adjustability: Requires use of CH1 and CH2. Independently adjustable aileron/elevator travel. Adjustable aileron differential.
NOTE: If ELEVON is active, you cannot activate FLAPERON or AILVATOR. You must inhibit the last function to activate ELEVON. NOTE: Be sure to move the elevator and aileron sticks to full deflection during setup. If a large amount of travel is specified, when the AILERON and ELEVATOR STICKS are moved at the same time the controls may bind. (For details on setting up a complex aerobatic plane, such as "space shuttle" style controls, please visit www.futaba-rc.com\faq\faq-7c.html. Many other setup examples are also available at this location.) GOAL of EXAMPLE: Activate ELEVON. Adjust aileron differential to +10%. Activate the function.

Snap Rolls at the flick of a switch (SNAP-ROLL) (ACRO):
This function allows you to execute snap rolls by flipping a switch, providing the same input every time. It also removes the need to change dual rates on the 3 channels prior to performing a snap, as SNAP-ROLL always takes the servos to the same position, regardless of dual rates, inputs held during the snap, etc. Note: Every aircraft snaps differently due to its C.G., control throws, etc. Some models snap without aileron; others snap on elevator alone. Most models snap most precisely with a combination of all 3 surfaces. Additionally, rate of speed and acceleration when using the snap switch will affect how the model snaps. For information on using gyros with airplanes for cleaner precision maneuvers, such as snaps and spins without over rotation, see p. 56. Adjustability: Travel: Adjust the amount and direction of elevator , aileron and rudder travel. Range: -120 to +120 on all 3 channels. Default is 100% of range of all 3 channels. Directions: (up/right, down/right, up/left, down/left). This snap-roll function is fully adjustable regarding travels and direction on each of the 3 channels. AIL ELE RUD Right positive(up) + + + Right negative(down) + Left positive(up) + Left negative(down) + Note:Always deactivate the TRAINER function prior to activating SNAP-ROLL function.

Set up programmable mixes: see p. 53. View additional setups on the internet: www.futaba-rc.com\faq\faq-7c.html.
MIXES: the backbone of nearly every function Mixes are special programs within the radio that command one or more channels to act together with input from only one source, such as a stick, switch or knob. There are a variety of types of mixes. Types: Linear: Most mixes are linear. A 100% linear mix tells the slave servo to do exactly what the master servo is doing, using 100% of the slave channel's range to do so. An example is FLAPERON. When aileron stick is moved, the flap servo is told to move exactly the same amount. A 50% linear mix would tell the slave servo, for example, to move to 50% of its range when the master's control is moved 100%. Offset: An OFFSET mix is a special type of linear mix. When the mix is turned on (usually a flip of a switch), the slave servo is moved a set percent of its range. An example of this is AIRBRAKE --- moving flaps, flaperons, and elevator all to a set position at the flip of a switch. (see p. 52.) Essentially every feature in the radio's programming is really a mix, with all assignments/programming set up and ready to use. Additionally, the7C ACRO and HELI programs provide 3 linear fully-programmable mixes that allow you to set up special mixes to resolve flight difficulties, activate additional functions, etc. Let's look quickly at a few examples that are features we've already covered. This may help to clarify the mix types and the importance of mixes. Additional examples: Exponential is a preprogrammed curve mix that makes the servos response more (+) or less (-) sensitive around center stick (works in conjunction with dual rate, a linear mix that adjusts the total range). see D/R,EXP, p. 33. THR-CUT is an OFFSET pre-programmed mix. This tells the throttle servo, when below a certain point, to move toward idle an additional set percentage to help close the carburetor. See p. 32. ELEV-TO-FLAP mixing is a pre-programmed linear mix to move the flaps proportionally to elevator control, helping the model loop even tighter than it can on elevator alone. (see p. 49.) Next, we'll get an in-depth look at some pre-programmed mixes (mixes whose channels are predefined by Futaba for simplicity) we've not covered yet, and last, look at the fully-programmable mix types.

Adjustability: Defaults : The 3 programmable mixes default to aileron to rudder mixes. PROG.MIX1-3 aileron-to-rudder for coordinated turns
Channels available to mix: All three mixes may be changed to use any combination of CH1-7. Offset may also be set to the master channels. (see below.)
Master: The controlling channel. The channel whose movement is followed by the slave channel. Another channel: Most mixes follow a control channel. (Ex: rudder-to-ailerons, 25%, no switch, corrects roll coupling.) MASTER SLAVE SWITCH & POSITION RATE OFFSET RUDD AILE NULL (--) 25% center(default) Offset as master: To create an OFFSETmix, set the master as OFST. (Ex: move flap 20% of their total throw when SWITCH A is in down position.) MASTER SLAVE SWITCH & POSITION RATE OFST CH6 A DOWN 20%
Slave: The controlled channel. The channel that is moved automatically in response to the movement of the master channel. The second channel in a mixs name (i.e. aileron-to-rudder). On/off choices: SWITCH: Any of the positions of any of the 5 switches may be used to activate a mix. Up&Cntr, Cntr&Dn options allow the mix to be ON in 2 of the 3 positions of a 3-position SWITCH. NULL (--): No SWITCH can turn this mix OFF. This mix is active at all times. Rate: the percentage of the slave's range it will move upon maximum input from the master channel. Ex: RUDDERAILERON mix, 50%. Ail range=1". When rudder is moved full right, ailerons move 1/2". MASTER SLAVE SWITCH & POSITION RATE OFFSET RUDD AILE NULL (--) 50% center(default) Offset: Offsets the slave's center relative to the master. Ex: Smoke valve opens wider per throttle servo position when smoke SWITCH is ON. Smoke servo's neutral is moved down from THROTTLE STICK center to the bottom. MASTER SLAVE SWITCH & POSITION RATE OFFSET THRO CH7 E DOWN 0%(Hi) half throttle(default) 100%(Lo) *Assign the CH7 switch to NULL(--). See p.28.
GOAL of EXAMPLE: Set up a Smoke system: ON when SWITCH E is in the down position. *Adjust the CH7 switch to NULL prior to this setting. See page. 28.

To adjust the warning point, set a THROTTLE STICK POSITION in F/S. 40 BEEP: Tone emitted by transmitter to signify a variety of situations. See Error messages. Binding: Friction in a joint exceeding the movement of the linkage. Sticking or inability to continue movement. The servo continues to attempt to move the surface beyond its power/capabilities, rapidly draining battery power as it continues to struggle. Buddy Box: See Trainer box.
CCPM: Cyclic (pitch and roll) Collective Pitch Mixing. Multiple servos work in unison on the helicopters head to create one or more of the control functions. Ex: 3 servos set at 120 degrees operate the entire head. The 2 forward servos work together to rotate both the blades pitch and the roll cyclic (aileron) in a HR3 head type. See MODEL TYPE,HELI. Charge: To increase the electrical energy, measured as voltage, available in a battery pack. See Battery care and charging.

Delta peak charger: Common name for a specialized charger designed and required to properly peak charge both NiMH and NiCd batteries, actually called a Zero Delta V Peak Charger. See Battery Care and Charging. Dial: Transmitters rotary control and button used in various ways during programming.11 Differential: Uneven movement in each direction of a control surface. Usually used when discussing ailerons or when describing an undesirable unevenness in movement of other controls. See Twin aileron servos. Diode: An electronic device which only allows current to flow one direction. Used to protect radio against power surge and reversed polarity during charging.14 Discharge: To deplete the electrical energy in a battery pack, usually to its lowest safe voltage, for storage or as a part of regular maintenance. See Battery care and charging. Dual aileron servos: (ACRO ) a model using 2 servos on 2 separate channels to operate ailerons. May include flaperon action.

Dual rates (D/R,EXP): Reduce/increase the servo travel by flipping a switch (or by stick position). Used to make model more comfortable to fly in different maneuvers. 7C supports triple rates by simply assigning dual rates to 3 position switches. Includes exponential function, see EXP.33

Heading-hold gyro: Gyro that specifically measures the unwanted deflection angle and compensates until a corresponding angle has been returned. See Gyros. HELI: Model type, rotary wing. See MODEL TYPE. Helicopter radio: Transmitter that includes helicopter-friendly switch and control layout and suf icient programming to f at least support a 5-channel helicopter. The 7CA and 7CH radios both contain all needed programming. The 7CH has a more heli-friendly layout (through switch positioning and no ratchet on throttle for easier hovering) High Rate: See D/R,EXP. Hover: To maintain a stationary position relative to a point on the ground. HOVERING PITCH: see Hovering setups. HOVERING THROTTLE: see Hovering setups.

Inhibit: Makes a feature inactive/unable to be used. When a function is inhibited, it cannot be used even if the assigned switch is ON. Turns off functionality without losing any settings. Only visible in specific features. Installation: Radio installation and setup.16 Inverted: To fly a model upside-down. Inverted flight control programming: Not available in the 7C. Most modelers no longer use this "crutch" to fly inverted, instead learning to recognize the model' s behaviors when inverted and compensate appropriately.
Kill switch: (1) Throttle cut switch to close carburetor (see THR-CUT, p. 32). (2) gasoline ignition engine kill switch which removes spark to the plugs to stop the engine.56
Linear Mix: A mix that maintains the same relationship of master to slave throughout the whole range. Ex: a mix from one flap servo to another flap servo at 100% causes the 2nd servo to follow the first servo's movement exactly through all points of travel. See Programmable mix. Lithium battery: see Backup battery. LOW BATTERY warning: Transmitter's battery is below a safe flight voltage. Recharge immediately. See Error messages. Low rate: see D/R, EXP.
Master: The primary control. See Programmable mix. Mechanical gyro: Uses a mechanical gyroscope (like a child's toy gyro) to sense change of angle. See Gyros. MHz: Megahertz. Unit used to express frequency. Mix, mixing rate, mix offset: see Programmable mix. MIXER ALERT warning: Notifies user that a mix is activated which is not considered desirable for engine startup. See Error messages. Mode: Definition of which channels are assigned to which STICK movements. All 7C radios shipped in the US are Mode 2, with elevator and aileron on the right STICK. To change mode, please visit www.futaba-rc.com. MODE/PAGEBUTTON: Control button on radio's face used in various parts of programming.11 MODEL COPY: Used to duplicate the settings of one model already in memory into a second model memory. Often used to set up 2 similar models, or make a copy of a working model to experiment with new setups. 26 MODEL NAME: Gives each model memory an 6-character name for easy recognition. In MODEL submenu.27 MODEL RESET: Restore all data in a single model memory to defaults, including name and model type. See RESET. MODEL SELECT: Choose the model memory you wish to modify or fly. In MODEL submenu.25 MODEL TYPE: Select the type of model the aircraft is, including airplane and 6 heli types.28

Range check or test: To test the transmitters control over the model at a specific distance as a precaution in checking its proper operation prior to flight.16 Rate: Amount of control given. Ex: see Programmable mix. RESET: To delete all data in the existing model only. User CAN NOT erase all data in the radio. Only service center can do so. Part of PARAMETER submenu.28 Retractable landing gear: Landing gear that is brought up into the model during flight.56 REVERSE: Servo reversing. Used to reverse the direction of a servo to ease installation and set up.30 Rudder-to-aileron mix: (ACRO ) Used to counteract undesirable roll (roll coupling) that happens with rudder input, especially in knife-edge. Gives proper aileron input to counteract roll coupling when rudder is applied. Not a preprogrammed mix. See Programmable mix. This is the default programming for one linear and one curve mix in ACRO. Rudder-to-elevator mix: Used to counteract undesirable pitch (pitch coupling) with rudder input, especially in knife edge flight. Not a preprogrammed mix. See Programmable mix. Rudder-to-throttle mix: (HELI) Adds throttle to counter the added load from increasing pitch of the tail blades, maintaining a constant head-speed with rudder. (This is a minor effect and is not critical in most helicopters.) Not a preprogrammed mix. See Programmable mix. Rx: Receiver
SELECT (CURSOR) BUTTONS: Controls used in various ways during programming.11 Select a model: see MODEL SELECT. Service Center.3 Servo reversing: see REVERSE. SET: To accept. Usually done by pressing and holding the dial when instructed. Slave: Channel that moves in response to the command of the master. See Programmable mix. Smoke system: Injects a specialized smoke oil into the hot exhaust to create air-show like smoke trails.56 SNAP ROLL: (ACRO) Combines rudder, elevator and aileron movement to cause the aircraft to snap or spin at the flip of a switch.47 Stick adjustments: Change stick tension and height.15 SUB-TRIM: Used to fine tune the center or neutral point of each servo. Allows full trim function from the trim sliders for flight trimming.39 SWASH AFR: (HELI,CCPM types only) Adjustment of the travel of all servos involved in the particular control's movement only during the movement of that control. Ex: reverse the direction of movement of collective pitch while not affecting the direction of movement of either cyclic control.63 Swashplate type: (HELI). Part of the model type selection process. Selects specific heli swashplate geometry, such as one of four available types of "CCPM.".61 SWASH-THR: (HELI, CCPM types only) Corrects slowing of engine speed caused by swash plate operation at aileron or elevator operation. See throttle mixing. 72 Switch programmability: MANY features are reassignable to a variety of switches, including simply moving an auxiliary control such as flaps from the stock dial to a switch or other location.

The RBRC SEAL on the nickel-cadmium battery contained in Futaba products indicates that Futaba Corporation of America is voluntarily participating in an industry-wide program to collect and recycle these batteries at the end of their useful lives, when taken out of service within the United States. The RBRC program provides a convenient alternative to placing used nickel-cadmium batteries into the trash or municipal waste system, which is illegal in some areas. (for USA)
You may contact your local recycling center for information on where to return the spent battery. Please call 1-800-8-BATTERY for information on Ni-Cd battery recycling in your area. Futaba Corporation of Americas involvement in this program is part of its commitment to protecting our environment and conserving natural resources.

Meaning of Special Markings Pay special attention to safety where indicated by the following marks: DANGER - Procedures which may lead to dangerous conditions and cause death/serious injury if not carried out properly. WARNING - Procedures which may lead to a dangerous condition or cause death or serious injury to the user if not carried out properly, or procedures where the probability of superficial injury or physical damage is high. CAUTION - Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or physical damage, if not carried out properly. = Prohibited = Mandatory
Warning: Always keep electrical components away from small children.
FLYING SAFETY To ensure the safety of yourself and others, please observe the following precautions: Have regular maintenance performed. Although your 7C protects the model memories with non-volatile EEPROM memory (which does not require periodic replacement) and not a battery, it still should have regular checkups for wear and tear. We recommend sending your system to the Futaba Service Center annually during your non-flying-season for a complete checkup and service. Ni-Cd Battery Charge the batteries! (See Charging the Ni-Cd batteries, p. 14, for details.) Always recharge the transmitter and receiver batteries for at least 15 hours before each flying session. A low battery will soon die, causing loss of control and a crash. When you begin your flying session, reset your 7C's built-in timer, and during the session pay attention to the duration of usage. Stop flying long before your batteries become low on charge. Do not rely on your radios low battery warning systems, intended only as a precaution, to tell you when to recharge. Always check your transmitter and receiver batteries prior to each flight.

NOTE: If you need to remove or replace the transmitter battery, do not pull on its wires to remove it. Instead, gently pull on the connector's plastic housing where it plugs into the transmitter. SWITCH ASSIGNMENT TABLE
The factory default functions activated by the switches and knobs for a Mode 2 transmitter are shown below. Most 7C functions may be reassigned to non-default positions quickly and easily. Basic control assignments of channels 5 & 7 are quickly adjustable in PARA (see p. 28). For example, the channel 5
servo, which defaults to SWITCH E for retract use, can easily be unassigned (NULL to allow for easy use as a second ) rudder servo in a mix, or to a dial for bomb door or other control. Note that most functions need to be activated in the programming to operate. Mode 1 transmitter functions are similar but reverse certain switch commands. Always check that you have the desired switch assignment for each function during set up.

Mode 2 transmitter with rear cover removed.
You may adjust the tension of your sticks to provide the feel that you prefer for flying. To adjust your springs, youll have to remove the rear case of the transmitter. First, remove the battery cover on the rear of the transmitter. Next, unplug the battery wire and remove the battery from the transmitter. Next, using a screwdriver, remove the four screws that hold the transmitters rear cover in position, and put them in a safe place. Gently ease off the transmitters rear cover. Now you'll see the view shown in the figure above. Using a small Phillips screwdriver, rotate the adjusting screw for each stick for the desired spring tension. The tension increases when the adjusting screw is turned clockwise. When you are satisfied with the spring tensions, reattach the transmitter's rear cover. Check that the upper printed circuit board is on its locating pins. When the cover is properly in place, reinstall and tighten the four screws. Reinstall the battery cover. Adjusting Display Contrast To adjust the display contrast, from the home menu press and hold the End button. Turn the dial while still holding End button: clockwise to brighten counterclockwise to darken the display Let go off the dial and the button. Changing Modes: Hold down the MODE and End buttons while turning on the transmitter. The screen reads "STK-MD". Change this to the correct mode. Note that this will NOT change the throttle and elevator rachets, etc. Those are mechanical changes that must be done by a service center.
RADIO INSTALLATION While you are installing the battery, receiver, switch harness and servos into your model's fuselage, please pay attention to the following guidelines:

Wood screw

Rubber grommet Brass eyelet Servo mount or rail
Use the supplied rubber grommets when you mount each servo. Be sure not to over-tighten the screws. If any portion of the servo case directly contacts the fuselage or the servo rails, the rubber grommets will not dampen the vibration, which can cause mechanical wear and servo failure.
Servo Throw Once you have installed the servos, operate each one over its full travel and check that the pushrod and output arms do not bind or collide with each other, even at extreme trim settings. Check to see that each control linkage does not require undue force to move (if you hear a servo buzzing when there is no transmitter control motion, most likely there is too much friction in the control or pushrod). Even though the servo will tolerate loads, any unnecessary load applied to the servo arm will drain the battery pack quickly. Switch Harness Installation When you are ready to install the switch harness, remove the switch cover and use it as a template to cut screw holes and a rectangular hole slightly larger than the full stroke of the switch. Choose a switch location on the opposite side of the fuselage from the engine exhaust pipe, and pick a location where it cant be inadvertently turned on or off during handling or storage. Install the switch so it moves without restriction and snaps from ON to OFF and vice versa. Receiver Antenna It is normal for the receiver antenna to be longer than the fuselage. DO NOT cut or fold it back on itself --- cutting or folding changes the electrical length of the antenna and may reduce range. Secure the antenna to the top of the vertical fin, and let the excess wire length trail behind. 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 fiber pushrods or cables. Be sure to perform a range check before flying. Receiver Notes When you insert servo, switch or battery connectors into the receiver, note that each plastic housing has an alignment tab. Be sure the alignment tab is oriented properly before inserting the connector. To remove a connector from the receiver, pull on the connector housing rather than the wires. If your aileron servo (or others) are too far away to plug into the receiver, use an aileron extension cord to extend the length of the servo lead. Additional Futaba extension cords of varying lengths are available from your hobby dealer. Always use an extension of the proper length. Avoid plugging multiple extensions together to attain your desired length. If distance is greater than 18" or multiple or high current draw servos are being used, use Futaba Heavy-Duty servo extensions. Receiver Vibration and Waterproofing The receiver contains precision electronic parts. Be sure to avoid vibration, shock, and temperature extremes. For protection, wrap the receiver in foam rubber or other vibration-absorbing materials. It is also a good idea to waterproof the receiver by placing it in a plastic bag and securing the open end of the bag with a rubber band before wrapping it with foam rubber. If you accidentally get moisture or fuel inside the receiver, you may experience intermittent operation or a crash. If in doubt, send the receiver for service.

Trim step : changes the rate at which the trim moves when the TRIM LEVER is activated. It may be set from 1 to 40 units, depending on the characteristics of the aircraft. Most ordinary aircraft do well at about 2 to 10 units. Generally larger trim steps are for models with large control throws or for first flights to ensure sufficient trim to properly correct the model. Smaller trim steps are later used to allow very fine adjustments in flight.

to new setting.

SUB-TRIM: makes small changes or corrections to the neutral position of each servo. Range is -120 to +120, with 0 setting, the default, being no SUB-TRIM.
We recommend that you center the digital trims before making SUB-TRIM changes, and that you try to keep all of the SUB-TRIM values as small as possible. Otherwise, when the SUB-TRIMs are large values, the servo's range of travel is restricted on one side. The recommended procedure is as follows: measure and record the desired surface position; zero out both the trims (TRIM RESETmenu) and the SUB-TRIMs (this menu); mount servo arms and linkages so that the control surface' s neutral is as correct as possible; and use a small amount of SUB-TRIM to make fine corrections. GOAL of EXAMPLE: Adjust the flap servo's SUB-TRIM until its center exactly matches the aileron servo's center, as they are to work together as flaperons. STEPS: Open BASIC menu, then open SUB-TRIM. Choose the channel to adjust, and adjust until surfaces match. (Ex: flap) as needed. Repeat for other channels. Close. Where next? Adjust trim steps: see p. 39. Adjust END POINTs: see p. 32. Set up dual/triple rates and exponential (D/R,EXP): see p. 34. as needed. to each channel, INPUTS: for 1 second. (If ADVANCE, to SUB-TRIM.

NOTE: Only one of the two wing-type functions (FLAPERON and ELEVON) can be used at a time. Both functions , cannot be activated simultaneously. To activate a different wing type, the first must be deactivated. GOAL of EXAMPLE: De-activate FLAPERON so that ELEVON can be activated. STEPS: Open the FLAPERON function. INPUTS: for 1 second.(If basic, to FLAPERON. De-activate the function. Close function. Where next? Set up ELEVON(see p. 45). to INH.
Using FLAPERON (ACRO): The FLAPERON mixing function uses one servo on each of the two ailerons, and uses them for both aileron and flap function. For flap effect, the ailerons raise/lower simultaneously. Of course, aileron function (moving in opposite directions) is also performed.
Once FLAPERON is activated, any time you program CH6 or "Flap" (ie. FLAP-ELEVATOR mixing), the radio commands both servos to operate as flaps. A trimming feature is also available (see FLAP-TRIM) to adjust both neutral positions together for straight-and-level flight or slight increases/decreases of the flap angle. END POINT and SUB-TRIM both still adjust each servo individually. Second aileron servo (AIL-2): The default for the second aileron servo is CH6 and this allows both servos to work as ailerons and flaps. If CH5 or CH7 is selected the flap function only works CH6, and the two aileron servos function only as ailerons except in the air brake (A. BRAKE) function. In the air brake function the flap servo CH6 and the aileron servos CH1 and (CH5 or CH7) work together.
GOAL of EXAMPLE: Activate twin aileron servos, FLAPERON. Input 10% more up travel than down travel (aileron differential) within the FLAPERON programming.
STEPS: Open the FLAPERON function.
INPUTS: for 1 second. (If basic, * to FLAPERON.
Activate the function. Optional: adjust the aileron differential.(Ex: +10%) Optional: If using a 5 channel receiver, change AIL-2 from CH6 to CH5. Close menu. to +10%. to CH5.
Set FLAP-TRIM: see p. 44. Set up AIRBRAKE mix: see p. 52. View additional model setups on the internet: www.futaba-rc.com/faq/faq-7c.html
*If the FLAPERON function does not activate there is a conflicting mix act such as ELEVON.
FLAP-TRIM allows the flap action to be set in a way that it can be adjusted with the VR dial. AIRBRAKE will also move the flaps to a specified position via movement of a switch. The flaps can also be moved with switch using a programmable mix. See offset as master p.53.
Add FLAP-TRIM to allow the model's ailerons to drop 30% together as flaps from the VR dial.

Open FLAP-TRIM.

for 1 second.(If basic, to FLAP-TRIM.

Adjustability: Rate: -100% to +100, with a default of +50% (one-half of the rudder range is achieved when the AILERON STICK is pulled to provide full left or right aileron.)
GOAL of EXAMPLE: Activate AILE-RUDD mixing. Adjust rudder travel to 45%.
STEPS: Open the AILE-RUDD function.
INPUTS: for 1 second.(If basic, to AILE-RUDD.

AIRBRAKE mixing(ACRO):

Like FLAPERON, AIRBRAKE is one function that is really made up of a series of pre-programmed mixes all done for you within the radio. AIRBRAKE simultaneously moves the flap and elevator, and is usually used to make steep descents or to limit increases in airspeed in dives.
This function is often used even on models without flaps as an easy way to use the flaperons. Adjustability: Activation: set positions by flipping SWITCH G. Provides AIRBRAKE response immediately upon switch movement, going to a pre-set travel on each active channel without any means of in-flight adjustment. Channels controlled: Elevator and flap may be set independently in AIRBRAKE , including set to 0 to have no effect. Note: If using FRAPERON with channel 5 or 7 the AIRBRAKE has separate settings for the aileron servos working as flaperons and the flap.
GOAL of EXAMPLE: Activate AIRBRAKE on a FLAPERON model. Adjust the flap travel to 50%, with negative elevator (push) of 10%.
STEPS: Confirm FLAPERON is active. Open the AIRBRAKE function.
INPUTS: see FLAPERON instructions. for 1 second.(If basic, to AIRBRAKE.
Activate the function. Adjust the travels as needed. (Ex: Flap 50%, Elevator -10%.)

PROGRAMMABLE MIXES (PROG.MIX1-3):
Your 7C contains three separate linear programmable mixes. There are a variety of reasons you might want to use these mixes. A few are listed here. Sample reasons to use linear programmable mixes: To correct bad tendencies of the aircraft (such as rolling in response to rudder input). To automatically correct for a particular action (such as lowering elevator when flaps are lowered). To operate a second channel in response to movement in a first channel (such as increasing the amount of smoke oil in response to more throttle application, but only when the smoke switch is active). To turn off response of a primary control in certain circumstances (such as simulating one engine flaming-out on a twin, or throttle-assisted rudder turns, also with a twin).
Adjustability: Defaults : The 3 programmable mixes default to aileron to rudder mixes. PROG.MIX1-3 aileron-to-rudder for coordinated turns
Channels available to mix: All three mixes may use any combination of CH1-7. Offset may also be set to the master channels. (see below.)

HELICOPTER MODEL FUNCTIONS Please note that nearly all of the BASIC menu functions are the same for airplane (ACRO setup) and helicopter (H-1/H-2/HR3/HN3/H-3/HE3) setups.

GETTING STARTED WITH A BASIC HELICOPTER This guideline is intended to help you set up a basic ( H-1 ) heli, to get acquainted with the radio, to give you a jump start on using your new radio, and to give you some ideas and direction on how to do even more with this powerful system than you may have already considered. It follows our basic format of all programming pages: a big picture overview of what we're trying to accomplish; a "by name" description of the steps to help acquaint you with the radio; and then a step-bystep instruction to leave out the mystery and challenge of setting up your model. Briefly, the typical helicopter's controls are as follows: Aileron: changes cyclic lateral (roll). Rolls the helicopter. Tilts the swashplate to the left or right. CH1. Elevator: changes cyclic pitch. Changes the helicopter's angle of attack (nose up or nose down). Tilts the entire swashplate fore and aft. CH2. Rudder: changes the angle of the tail rotor. Yaws the helicopter left or right. CH4. Collective Pitch: adjusts main rotor collective [angle of the paddles], changing the main blades' pitch. Increased collective pitch (with throttle) causes the helicopter to rise. Moves in conjunction with throttle on the THROTTLE STICK. CH6. Throttle: opens/closes carburetor. Moves in conjunction with collective pitch on the THROTTLE STICK. CH3. REVO: mix that 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 headinghold/AVCS mode. However, revo. mixing is still used when a heading-hold/AVCS gyro is in normal mode.) For additional details, see that function's section in this manual. The page numbers are indicated in the first column for you.

With THROTTLE STICK at idle, adjust the rate until the engine consistently shuts off, but throttle linkage is not binding.1

Set up collective pitch curve for normal as base of -4, center of +5, end of +8 to +10 degrees of blade pitch for aerobatics.2 (If just learning to fly, ask your instructor.) P. 65. Set up revo. mixing for normal. (For heading-hold gyros, inhibit revo.) P. 65.
Open the PIT-CV/NOR function. Adjust each point to match desired curve. (Ex first point: 89%.) Close the function. Open the REVO-MIX function. Adjust to your desired starting point. (Ex: 10%.) Close the function.
to PIT-CV/NOR. to 89%. to next point. Repeat.
to REVO-MIX. to ON. to 10%. to 15%.
Confirm Gyro direction. (Note: if using a heading-hold/AVCS gyro, use the GYRO programming for proper setup. See p. 72.)
With radio on, move helicopter's tail to the right by hand. The gyro should give right rudder input (leading edge of the tail rotor blades move left). If the gyro gives the opposite input, reverse direction on the gyro unit itself.
Be sure to follow your model' s instructions for preflight checks, blade tracking, etc. Never assume a set of blades is properly balanced and will track without checking. Check receiver battery voltage! Always check voltage with a voltmeter prior to each and every engine start. (Never assume being plugged in all night means your radio gear is ready to fly). Insufficient charge, binding servo linkages, and other problems can result in a dangerous crash with the possibility of injury to yourself, others and property. Confirm the swashplate is level at 0 travel. Adjust arms if needed. Apply full collective and check that the swashplate remained level and there is no binding. Repeat for full cyclic pitch and roll. If not, adjust as needed to correct in END POINT: see p. 32. Important note: prior to setting up throttle hold, idle-ups, offsets, etc., be sure to get your normal condition operating properly. Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and having completed all range checks, etc, gradually apply throttle until the helicopter becomes "light on the skids." Adjust trims as needed to correct for any roll, pitch, or yaw tendencies. If the tail "wags," the gyro gain is too high. Decrease gyro gain. Where next?(Other functions you may wish to set up for your model.) THROTTLE HOLD: P. 67. SUB-TRIM p. 40 and separate trims for conditions (OFFSETS): p. 70. IDLE-UP p. 69. Rudder-to-throttle and other programmable mixes p. 53.
Periodically move the throttle stick to full and back down to ensure proper servo settings. It is critical that dials VR be centered when the pitch and throttle curves are setup.

Since these types utilize multiple servos together to create the controls, simply adjusting a servo' s REVERSE or END POINT would not properly correct the travel of any one control. Since H-1uses one servo for each function, there is no need for AFR in H-1. This is fairly hard to explain but easy to see, so let' s set up Kyosho Caliber's swashplate settings as an example. With everything installed per factory instructions, set the model to HELI(HR3). Now let's adjust the swashplate properly. Since aileron always uses no more than 2 servos, check it first. Either both operate properly (no change needed), both operate backwards (reverse the whole function), or one servo operates backwards (reverse that servo alone). Next check elevator. Remember, the aileron servo(s) operate correctly, so if elevator does not, we should only have 2 choices left - the whole function needs to be reversed, or the servo(s) not shared with aileron need to be reversed. Last is collective. If aileron and elevator are working properly, the only thing that could be wrong is the whole direction collective operates (reverse the whole function). In our example, HR3 is 180 degrees off from the swashplate of the Caliber. The collective pitch operation is backwards; but reversing all three servos would also reverse the aileron and elevator operations. Changing the collective pitch rate, however, from +50% to -50%, will reverse the collective pitch without affecting the aileron action.

*These default recommendations assume you are doing forward flight. If you are just learning, please follow your instructor's guidance. Some instructors like a +1 base point for training so that the helicopter comes down very slowly, even if your instincts pull the throttle/collective stick to the bottom in a hurry.
GOAL of EXAMPLE: Set up Normal Flight Condition Throttle/Collective Pitch Curves and Revo. Base point: Adjust base point of throttle curve until engine idles reliably on ground. Adjust base point of collective pitch curve to achieve -4 degrees of blade pitch. Apply throttle until the model sits "light" on its skids. Adjust base point of REVO. until model does not rotate its nose at all. Hover point: Adjust collective pitch curve to +5 degrees. Ease heli into a hover. Land/shut engine off. Adjust throttle curves and rudder trim. Repeat until model hovers smoothly at half throttle. Rapidly apply throttle from 1/4 to 1/2 stick. Adjust REVO. points 2 and 3 until the model does not rotate its nose upon throttle application. High point: Adjust collective pitch curve to +8 to +10 degrees. From hover, throttle up rapidly. If engine bogs, increase the throttle curve. If engine over-revs, increase the collective pitch curve at points 4 or 5. Apply full throttle while hovering, then descend back to hover. Adjust REVO. until the nose does not change heading. Where next?
STEPS: Open the THR-CV/NOR function. Adjust the first point. (Ex: 5%.) Open the PIT-CV/NOR function. Adjust the first point. (Ex: 8%.) Open the REVO. function. (Ex: High 5%, Low 10%.) Adjust THR-CV/NOR. Adjust PIT-CV/NOR.
INPUTS: for 1 second.(If ADVANCE, to THR-CV/NOR. to 5%. to PIT-CV/NOR. to 8%. to REVO. to 5%. to 10%. Repeat above as needed. Repeat above as needed.

THROTTLE CUT: The THR-CUT function is used to kill the engine at the end of a flight. The engine can be stopped with one touch of any switch, eliminating the need to move the trim to kill the engine and then readjust prior to each flight. The helicopter THR-CUT includes an ON/OFF throttle position (normally a little above idle). You must move the THROTTLE STICK back below the set point before the THR-CUT function can be reset, to avoid sudden engine acceleration. For a detailed example of throttle cut setup, see ACRO p. 33. Note: Be sure to add the step of setting a trigger point by cursoring to THR, then putting the THROTTLE STICK in the desired position and pressing and holding the dial for one second. Notice that this function cannot be reversed to trigger only above the stick point.

Some instructors like a +1 base point for training so that the helicopter comes down very slowly, even if your instincts pull the throttle/collective stick to the bottom in a hurry.)
Adjustability: Normal condition curves are editable in the BASIC menu for convenience. All curves may be adjusted in the ADVANCE menu. Automatically selected with the proper condition. The idle-up curves are adjusted by the modeler to maintain constant RPM even when the collective pitch is reduced during flight (including inverted). To change which condition's curve is being edited, simply press the MODE/PAGE BUTTON to scroll through the curves available, or cursor up above point 1 and change the curve named. For clarity, the name of the condition currently active (switched on in the radio) is shown in parentheses behind name of condition whose curve is being edited. Idle-ups and throttle hold pitch curves may be edited even before the conditions have been made active or while they are active but not selected.
REVO. MIX: This linear curve mix adds opposite rudder input to counteract the changes in torque when the speed and collective pitch of the blades is changed. Adjustability: REVO.MIX: normal for hovering and idle-ups (1 and 2) combined. REVO.MIX is editable in the BASIC and ADVANCE menu.
Revo. mixing rates are linear curves. For a clockwise-turning rotor, the rudder is mixed in the clockwise direction when collective pitch is increased; for counterclockwise-turning, the opposite. Change the operating direction setting by changing the signs of the numbers in the curve from plus (+) to minus (-) and vice versa. Revo. curves for idle-ups are often v-shaped to provide proper rudder input with negative pitch and increased throttle during inverted flight. (Rudder is needed to counter the reaction whenever there is increased torque. In inverted flight, throttle stick below half has increased throttle and negative pitch, therefore increasing torque and rotating the helicopter unless the revo. mix is also increasing appropriately.)
IDLE-UPS: additional flight conditions available specifically for helicopters. These additional flight conditions contain different throttle curves, collective pitch curves, and trims to make the helicopter perform certain maneuvers more easily. Lastly, the gyro and dual rate functions may be set to provide separate rates per condition selected, including one for each idle-up. One of the most common flight conditions can easily flip from upright to inverted and back. To do so, the pitch curve is set to 0 pitch at half stick, positive pitch (climb upright) above half, and negative pitch (climb when inverted) below half stick. The throttle curve is adjusted to allow the engine to run consistently throughout the changes in pitch. Additional idle-ups may be used to maximize the helicopter's flight characteristics in certain types of flight (i.e. fast forward motion, backward) or maneuvers (loops, rolls, stall turns), or even the same maneuver but changing from headinghold/AVCS gyro mode to normal gyro mode. The 7C provides 2 idle-ups to allow the modeler 2 additional setups along with the normal flight condition. Adjustability: SWITCH G (7CA) or E (7CH) is programmed for normal (NORM), idle-up 1 (IDL1), and idle-up 2 (IDL2) curves. This switch/position assignment is not adjustable. Activated with the throttle curve for that condition in THR-CURVE.
