FLYING SAFETY WARNING To ensure the safety of yourself and others, please observe the following precautions:

Ni-MH/Ni-Cd Battery Charge the batteries! (See Charging the Ni-Cd batteries, for details.) Always recharge the transmitter and receiver batteries before each flying session. A low battery will soon die potentially, causing loss of control and a crash. When you begin your flying session, reset your T8FGS’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 radio’s 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.

Where to Fly Always pay particular attention to the flying field’s rules, as well as the presence and location of spectators, the wind direction, and any obstacles on the field. Be very careful flying in areas near power lines, tall buildings, or communication facilities as there may be radio interference in their vicinity

.

## 7 Ni-MH/Ni-Cd Battery Safety and Handling instructions

IMPORTANT! Use only the Futaba special charger included with this set or other chargers approved by Futaba to charge the Ni-MH batteries in the T8FGS transmitter included with this set.
It is important to understand the operating characteristics of Ni-MH/Ni-Cd batteries.Always read the specifications printed on the label of your Ni-MH/Ni-Cd battery and charger prior to use. Failure to follow the proceeding precautions can quickly result in severe, permanent damage to the batteries and its surroundings and possibly result in a FIRE!

IMPORTANT PRECAUTIONS
Do not attempt to disassemble Ni-MH/Ni-Cd packs or cells. Do not allow Ni-MH/Ni-Cd cells to come in contact with moisture or water at any time. Always provide adequate ventilation around Ni-MH/Ni-Cd batteries during char ge, discharge, while in use, and during storage. Do not leave a Ni-MH/Ni-Cd battery unattended at any time while being charged or discharged. Do not attempt to charge Ni-MH/Ni-Cd batteries with a charger that is NOT designed for Ni-MH/Ni-Cd batteries, as permanent damage to the battery and charger could result. Always charge Ni-MH/Ni-Cd batteries in a fireproof location. Do not charge or discharge Ni-MH/Ni-Cd batteries on carpet, a cluttered workbench, near paper, plastic, vinyl, leather or wood, or inside an R/C model or full-sized automobile! Monitor the charge area with a smoke or fire alarm. Do not charge Ni-MH/Ni-Cd batteries at currents greater than the “1C” rating of the battery (“C” equals the rated capacity of the battery). Do not allow Ni-MH/Ni-Cd cells to overheat at any time! Cells which reach greater than 140 degrees Fahrenheit (60°C) should be placed in a fireproof location. Ni-MH/Ni-Cd cells will not charge fully when too cold or show full charge. It is normal for the batteries to become warm during charging, but if the charger or battery becomes excessively hot disconnect the battery from the charger immediately!! Always inspect a battery which has previously overheated for potential damage, and do not re-use if you suspect it has been damaged in any way. Do not use a Ni-MH/Ni-Cd battery if you suspect physical damage has occurred to the pack. Carefully inspect the battery for even the smallest of dents, cracks, splits, punctures or damage to the wiring and connectors. DO NOT allow the battery’s internal electrolyte to get into eyes or on skin—wash affected areas immediately if they come in contact with the electrolyte. If in doubt, place the battery in a fire-proof location for at least 30 minutes. Do not store batteries near an open flame or heater. Do not discharge Ni-MH/Ni-Cd batteries at currents which exceed the discharge current rating of the battery. Always store Ni-MH/Ni-Cd cells/packs in a secure location away from children.

Never remove the SD card or turn off power while entering data. Never store the SD card where it may be subject to strong static electricity or magnetic fields. Do not expose the SD card to direct sunlight, excessive humidity or corrosive environments. Do not expose the SD card to dirt, moisture, water or fluids of any kind. Always hold the SD card by the edges during installation and removal. Be certain to insert the SD card in the correct direction. Secure Digital (SD) Memory Card Handling Instructions (SD card is not included with this set)

## 8 At the flying field

To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:

1. Pull throttle stick to idle position, or otherwise disarm your motor/engine. 2. Turn on the transmitter power and allow your transmitter to reach its home screen. 3. Confirm the proper model memory has been selected. 4. Turn on your receiver power. 5. Test all controls. If a servo operates abnormally, don’t attempt to fly until you determine the cause of the

problem. Test to ensure that the FailSafe settings are correct after adjusting them. Turn the transmitter off and confirm the proper surface/throttle movements. Turn the transmitter back on. 6. Start your engine. 7. Complete a full range check. 8. After flying, bring your throttle stick to idle position, engage any kill switches or otherwise disarm your

motor/engine. 9. Turn off receiver power. 10. Turn off transmitter power.

If you do not turn on your system in this order, you may damage your servos or control surfaces, flood your engine, or in the case of electric-powered or gasoline-powered models, the engine may unexpectedly turn on and cause a severe injury.

While you are getting ready to fly, if you place your transmitter on the ground, be sure that the wind won't tip it over. If it is knocked over, the throttle stick may be accidentally moved, causing the engine to speed up. Also, damage to your transmitter may occur. In order to maintain complete control of your aircraft it is important that it remains visible at all times

. Flying behind large objects such as buildings, grain bins, etc. is not suggested. Doing so may result in the reduction of the quality of the radio frequency link to the model. Do not grasp the transmitter's antenna during flight. Doing so may degrade the quality of the radio frequency transmission. As with all radio frequency transmissions, the strongest area of signal transmission is from the sides of the transmitter's antenna. As such, the antenna should not be pointed directly at the model. If your flying style creates this situation, easily move the antenna to correct this situation. Don’t fly in the rain! Water or moisture may enter the transmitter through the antenna or stick openings and cause erratic operation or loss of control. If you must fly in wet weather during a contest, be sure to cover your transmitter with a plastic bag or waterproof barrier. Never fly if lightning is expected.

"1 through 6": outputs for the channels 1 through 6. (Digital servo only in the High Speed mode.) "7", "8": outputs for the channels 7 and 8. (Analog or digital servos regardless of mode.) "B": connector for the power. "S.BUS": output for the S.BUS system.

The RGC08SB has two(2) operation modes as shown below.

Receiver Normal mode/High Speed mode The "Normal mode" accepts any type of servos or peripherals as the frame rate of the output is 14ms. The "High Speed mode" only accepts digital servos for outputs from 1ch to 6ch. This includes the BLS series, and most peripheral equipment such as gyros and brushless ESCs. The frame rate of the outputs is 7ms. The outputs from 7ch to 8ch allow the use of any type of servos as the frame rate of these outputs are still 14ms ever in the High Speed mode. 

## Receiver nomenclature

Before using the receiver, be sure to read the precautions listed in the following pages. The RGC08SB has an S.BUS system output port and a conventional system channel output. It can also be used with conventional system servos, etc. in addition to S.BUS system compatible servos and gyros, etc. In addition, the operating mode (high-speed mode/normal mode) can be selected.

Usage condition on "High Speed mode"



## CAUTION

When using the RGC08SB in the high speed (HS) mode, digital servos are required for the first six channels (1-6). If an analog servo is connected to one of the first six channels when in the high speed mode, the servo will not function properly. Additionally, while many peripheral devices will operate in either the high speed or normal mode, some will not. If there are any difficulties noted, please return the reciever's operational mode to the "Normal" mode to determine if this resolves the difficulty. If using the RGC08SB in the high speed mode, analog servos may be used for channels seven and eight. Link/Mode switch LED

* The LED corresponding to the setting mode blinks. Mode A: Red blinks 3 times Mode B: Green blinks 3 times 4. Turn off the receiver.

## 26 Easy Link (T8FGS/RGC08SB) 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 additional RGC08SB receivers, this procedure is necessary; otherwise the receiver will not work.

Link procedure
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 front

side of the transmitter to see if the RF signal is active. When the right LED is ON solid, the RF signal is being sent. 4. Turn on the receiver.

5. Press down the Link/Mode button for more

than two seconds, and release the switch. The receiver begins the linking operation. 6. When the linking is complete, the LED in the

receiver will change to solid green. Please confirm that the servos are now operational from your transmitter. Please refer to the table below for the LED status of the receiver's condition.

* If there are many FASST systems turned on around your receiver, it might not link to your transmitter. In this case, even if the receiver's LED stays solid green, unfortunately the receiver might have established a link to one of other transmitters. This is very dangerous if you do not notice this situation. In order to avoid the problem, we strongly recommend you to doublecheck whether your receiver is really under control by your transmitter by giving the stick input and then checking the servo response. 

### LED Indication (RGC08SB)

## Warning

After the linking is done, please cycle receiver power and check if the receiver to be linked is really under the control by the transmitter to be linked.
Do not perform the linking procedure with motor's main wire connected or with the engine operating as it may result in serious injury.

## 27 Range Testing Your R/C System

It is extremely important to range check your models prior to each flying session. This enables you to ensure that everything is functioning as it should and to obtain maximum enjoyment from your time flying. The T8FGS transmitter incorporates a system that reduces its power output and allows you to perform such a range check.

Range check mode

We have installed a special "Range check mode" for doing a ground range check. To access the "Range check mode" touch and hold the RTN button while turning on the transmitter. Doing so will bring up POWER MODE menu.

To activate the "Range check mode" touch the RTN button and the range check mode screen will
appear.

During this mode, the RF power output is reduced so the range test can be performed. In addition, when this mode is activated the right LED on the front of the transmitter starts blinking and the transmitter gives users a warning with a beeping sound every 3 seconds. The "Range check mode" continues for 90 seconds and after that the power will return to the normal level. To exit the "Range check mode" before the 90 seconds, select the "RANGE CHECK" at the top of the screen and touch the RTN button again. This mode is available one time only so if you need to re-use this function the transmitter power must be cycled. NEVER start flying when the "Range check mode" is active. Should you require additional time to perform a range check, highlight Restart before your time expires and press the RTN button one time. Range check procedure 1. With the "Range check mode" on, walk

away from the model while simultaneously operating the controls. Have an assistant stand by the model to confirm that all controls are completely and correctly operational. You should be able to walk approximately 30-50 paces from the model without losing control. 2. 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 or motor. Be certain the throttle stick is in the low throttle position, then start the engine or motor. Perform another range check with your assistant holding the aircraft with the engine running at various speeds. If the servos jitter or move inadvertently, there may be a problem. We would strongly suggest you do not fly until the
source of the difficulty has been determined. Look for loose servo connections or binding pushrods. Also, be certain that the battery has been fully charged. The present model

The receiver channel assignment depends on the model type. See the Servo connection by model type tables. 

## Receiver and servos connection Connect the receiver and servos in accordance with the connection diagram shown below. Always read [Precautions when mounting the receiver and servos] or [Before using]. When mounting the receiver and servos to the fuselage, connect the necessary points in accordance with the model's instruction manual.

• S.BUS system

Different from conventional radio control systems the S.BUS system uses data communication to transmit control signals from a receiver to a servo, gyro, or other S.BUS compatible device. This data includes commands such as “move the channel 3 servo to 15 degrees, move the channel 5 servo to 30 degrees” to multiple devices. The S.BUS devices execute only those commands for their own set channel. For this reason, it can be used by connecting multiple servos to the same signal line. [Connection by S.BUS system]

## 33 Precautions when mounting the receiver and servos

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 your aileron servo (or others) are too far away

to plug into the receiver, use a servo 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. • 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 airplane/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 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 won’t be inadvertently turned on or off during handling or storage. Be certain the switch moves without restriction and “snaps” from ON to OFF, and that the cutout allows full motion of the switch in both directions. • When you install the switch harness to the

helicopter, please use the switch cover. Generally sandwich the frame between the switch and switch cover and securely tighten the screws. Different models might require different installations. If so, please follow the model's instruction manual. • To prevent the servo lead wires from being

broken by vibration during flight, provide a slight amount of slack or extra 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.

## 34 Receiver's Antenna Installation You will note that the RGC08SB differs in appearance from the standard Futaba receiver. This receiver incorporate two separate antennas into their design which enables them to receive the radio frequency transmission at two different locations.
*Must be kept as straight as possible.

Coaxial cable Antenna

RGC08SB Receiver 

### Dual antenna diversity then seamlessly selects the best signal reception between these antennas to ensure that there is no loss of signal.

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 figure, 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 flying attitude. 3. The antennas must be kept away from conductive materials, such as metal, carbon and fuel tank 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 tight radius. 4. Keep the antennas away from the motor, ESC, and other noise sources as much as possible.

*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. *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, return the receiver to our service center for service. **Antenna**

# MODEL BASIC SETTING PROCEDURE

1. Model addition and selection

Initially, the T8FGS assigns the first model to model-01 in the transmitter. The Model Select function of the Linkage Menu is used to add models and to select amongst models which are already set.

The T8FGS is capable of storing data for up to 20 models in its internal memory. Additional model data can also be saved to an optional SD card.

The currently selected model name is displayed in the center of the home screen. Before flying and before changing any settings, always confirm the model name.

When a new model is added, the Model type select screen and FASST mode/Area select setup screen automatically appear. Please be aware that the transmitter will stop transmitting temporarily when you change the model.

2. Model type selection Select the model type matched to the aircraft with the Model Type select function of the Linkage Menu. For an airplane, select the model type from among the 2 types: airplane and glider. And then select the wing type and the tail type matched to the aircraft.

3. Fuselage linkage Connect the ailerons, elevators, throttle, rudder, etc. in accordance with the model's instruction 

## Airplane/glider basic setting procedure

manual. For a description of the connection method, see the Receiver and Servos Connection. Note that even for the same "airplane model", when the wing type and tail type are different, the channel assignment may be different. (The channel assigned to each function can be checked at the Function menu of the Linkage Menu.)

●	 If the direction of the servo is incorrect, adjust

the direction with the Reverse function of the Linkage Menu.

●	 Adjust the neutral position and control

surface angle with the linkage, and fine tune them with the Sub-Trim and End Point functions (angle adjustment). To protect the linkage, a limit position can also be set with the End Point function. The End Point function can adjust the amount of up/down and left/ right movement and limit of each channel.



### 4. Throttle cut setting (Airplane)

Throttle cut can be performed with one touch by a switch without changing the throttle trim position.
Set throttle cut with the Throttle Cut function of the Linkage Menu. After activating the throttle cut function and selecting the switch, adjust the throttle position so that the carburetor becomes fully closed. For safety, the throttle cut function operates the throttle stick in the 1/3 or less (slow side) position.

## 36 5. Idle down setting (Airplane) The idling speed can be lowered with one touch by a switch without changing the throttle trim position. Perform this setting with the Idle Down function of the Linkage Menu. After activating the Idle Down function and selecting the switch, adjust the idle down speed. For safety, the idle down function acts only when the throttle stick is in the lowest part of its throw.

*While the Throttle Cut function is in operation, the Idle Down function does not work.



### 6. D/R function

D/R function is used to adjust the throw and operation curve of the stick functions (aileron, elevator, rudder and throttle) for each switch position (airplane) or each flight condition (glider). This is normally used after the modeler has defined the maximum throw directions in the End Point settings.

(Airplane)

(Glider)

7. Airbrake (Airplane)

This function is used when an airbrake is necessary when taking off or diving, etc. Please note: this menu item is only available under certain wing configurations. For example, it will not appear if a single aileron wing type has been selected.

The pre-set elevator and flap offset amount can be activated by a switch. The offset amount of the aileron, elevator, and flap servos can be adjusted as needed. Also the speed of the aileron, elevator, and flap servos can be adjusted. You can also set the Auto Mode, which will link Airbrake to a stick, switch, or dial. A separate stick switch or dial can also be set as the ON/OFF switch.

8. Addition of flight conditions (Glider)

The Condition Select function automatically allocates the normal condition (NORMAL) for each model. NORMAL is the default condition and is the only one active when a new model type is defined.

If you want to add flight conditions, please refer to a description of the CONDITION function.

*The NORMAL is always on, and remains on until other conditions are activated by switches, stick positions, etc. Please refer to the section entitled Switch Selection Method for additional information on how to do so. *It is possible to customize the activation of the flight conditions. *The Condition Delay can be programmed for each channel. The Condition Delay is used to change the servo throw smoothly when switching conditions.

## 37 1. Model addition and selection

Initially, the T8FGS assigns the first model to model-01 in the transmitter. To add new models or to select a model already programmed, use the Model Select function of the Linkage Menu.

This is convenient when selecting a model after entering the model's names in advance. The T8FGS is capable of storing up to 20 models in the transmitter's internal memory. Additional models can also be stored in an optional SD card.

The currently selected model is displayed in the middle of the screen. Before flying and before changing any settings, always confirm the model

name.

When a new model is added, the Model Type select screen and Frequency setup screen automatically appear. Change, or check that they match the swash type and receiver type of the model used.

2. Model type and swash type selection

If a different model type is already selected, select helicopter with the Model Type function of the Linkage Menu, and then select the swash type matched to the helicopter.

*The Model Type function automatically selects the appropriate output channels, control functions, and mixing functions for the chosen model type. Six swash types are available for helicopters. *For a description of the swash type selection, refer to the MODEL TYPE function. 

## Helicopter basic setting procedure

This section outlines examples of use of the helicopter functions of the T8FGS. Adjust the actual values, etc. to match the fuselage used.

3. Flight condition addition The transmitter offers up to five flight co nditions per model.

The Condition Select function automatically allocates five conditions for helicopters. (Initial setting)

● NORMAL

● IDLE UP1 (SW-E)

● IDLE UP2 (SW-E)

● IDLE UP3 (SW-F) ●HOLD (Hold switch is not assigned initially) Note: Since you may accidentally activate a condition that not previously setup during flight which could cause a crash, we suggest deleting conditions that are not used. *For a description of the condition deletion, refer to the Condition Select function. 

### The NORMAL condition is always on, and remains on until other conditions are activated by switches.

The priority is throttle hold/idle up 3/idle up 2/idle up 1/normal. Throttle hold has the highest priority. The Condition Delay can be programmed for each channel and condition. The Condition Delay is used to change the servo throw smoothly when switching conditions.

(General flight condition setting example)

● Normal: (Use initial setting conditions/operate

when switch OFF) Use from engine starting to hovering.

● Idle up 1: (Operate at SW-E center)

Use in 540o stall turn, loop, rolling stall turn, and other

maneuvers.

● Idle up 2: (Operate at SW-E forward side)

Use in rolls.

● Throttle hold: (Operate at SW-G forward side)

Use in auto rotation.

## 38 5. Throttle/Pitch curve setting This function adjusts the throttle or pitch operation curve in relation to the movement of the throttle stick for each condition.

<Throttle curve setting example>

Activate the throttle curve of each condition with the condition select switch.
●Normal curve adjustment

Normal curve creates a basic throttle curve centered near hovering. This curve is adjusted together with the pitch curve (Normal) so that the engine speed is constant and up/down control is easiest. ●Idle up curve adjustment

The low side Throttle curve creates a curve matched for aerobatics (loop, roll, 3D, etc.). ●Throttle hold curve adjustment

The curve is not used when performing auto rotation dives.
Confirm that the rate of the slowest position (0%) of the stick is 0% (initial setting).



### < Example of pitch curve setting>

Activate the pitch curve of each condition with the condition select switch.
●Pitch curve (Normal)

Make the pitch at hovering approximately +5 o ~6 o

. Set the pitch at hovering with the stick position at the 50% point as the standard. *Stability at hovering may be connected to the throttle curve. Adjustment is easy by using the hovering throttle function and hovering pitch function together. ●Pitch curve (Idle up 1)

The idle up 1 pitch curve function creates a curve matched to airborne flight.
Set to -7 o ~+12 o as standard. ●Pitch curve (Idle up 2)

The high side pitch setting is less than idle up 1.
The standard is +8 o

. ●Pitch curve (Hold)

At auto rotation, use the maximum pitch at both the high and low sides. [Pitch angle setting example]
Throttle hold: -7 o ~+12 o 

### 4. Servo Connection Connect the throttle rudder, aileron, elevator, pitch, and other servos in accordance with the kit instruction manual. For a description of the connection method, see "Receiver and Servos Connection". Note: The channel assigned to each function can be checked at the Function menu of the Linkage Menu.

● If the direction of operation of the servo

is incorrect, use the Reverse function of the Linkage Menu. Also use the swash AFR function in other than the H-1 mode.

● Adjust the direction of operation of the gyro. (Gyro side function)

● Connect the throttle linkage so that the

carburetor can fully close at full trim throttle cut.

● Adjust the neutral position at the linkage side

and fine tune with the Sub-Trim function and End Point function. To protect the linkage, a limit position can also be set with the End Point function.

● Swash plate correction (Except H-1 mode)

*If any interactions are noticed, for a description of the linkage correction function, please refer to the SWASH function,.

## 39 for each condition. (At initial setting, this function is in the "INH" state. To use it, set it to the "ON" state.) <Setting example>

Activate the mixing curve of each condition with the condition select switch. A curve setting example is shown below. ●Pitch to RUD mixing curve (Normal)

Use the hovering system and set this curve to match take off and landing and vertical climb at a constant speed. ●Pitch to RUD mixing (Idle up 1)

Use this curve in 540 o stall turn, loop, and rolling stall turn, and adjust it so the fuselage is facing straight ahead when heading into the wind. ●Pitch to RUD mixing (Hold)

This function is set so that the fuselage is facing straight ahead at straight line auto rotation. The pitch of the tail rotor becomes nearly 0 o

. 

### 9. Throttle hold setting

*If throttle hold is necessary, please refer to the THR HOLD function.



### 10. Throttle cut setting

Throttle cut provides an easy way to stop the engine, by flipping a switch with the throttle stick at idle. The action is not functional at high throttle to avoid accidental dead sticks. The switch’s location and direction must be chosen, as it defaults to NULL.

*With throttle stick at idle, adjust the cut position until the engine consistently shuts off, but throttle linkage is not binding. 

### 11. Swash Mix corrects aileron, elevator and pitch interaction
The swash mix function is used to correct the swash plate in the aileron (Left/Right Cyclic) and elevator (Forward/Aft Cyclic) direction corresponding to each operation of each condition. 6. D/R function

D/R function is used to adjust the throw and operation curve of aileron, elevator and rudder for each condition.

*For throttle and pitch curve settings, refer to the aforementioned "Throttle/Pitch curve setting" 

### This is normally used after End Point has defined the maximum throw directions.

7. Gyro sensitivity and mode switching

The gyro sensitivity and mode switching function is utilized to adjust the gyro mixing of the model, and can be set for each condition.

●	 Normal condition (hovering): Gyro sensitivity

maximum ●	 Idle up 1/Idle up 2/Throttle hold: Gyro

sensitivity minimum ●	 However, during auto rotations with a taildriven helicopter, this function may not have any effect on the high gyro sensitivity.



### 8. Pitch to RUD mixing setting Note: When using a GY601, GY502, GY520, GY401, or other heading hold gyro, this Pitch to RUD mixing should not be used. The reaction torque is corrected by the gyro. When operating the gyro in the AVCS mode, the mixed signal will cause neutral deviation symptoms and the gyro will not operate normally.



### Use this function when you want to suppress the torque generated by the changes in the pitch and speed of the main rotor during pitch operation. Adjust it so that the nose does not swing in the rudder direction. However, when using a heading hold gyro like those shown above, do not use Pitch to rudder mixing.

Activate the Pitch to rudder (Pit -->RUD) mixing function from the Model Menu, and set the curve

## 40 12. Throttle mixing setting
*If throttle mixing is necessary for a compensation for

slowing of engine speed caused by swash plate operation during aileron or elevator operation, please refer to the THROTTLE MIX function.



### 13. Other special mixings
●Pitch to Needle mixing

This mixing is used with engines with a design which allows needle control during flight (fuel-air mixture adjustment). A needle curve can be set. ●Governor mixing

This mixing is dedicated governor mixing when a GV-1 (governor) is used.

# TRAINER Trainer system starting and setting



### The Trainer function makes it possible for the instructor to choose which functions (*1) 

### and channels are to be used for instruction, making it possible to match the training ability to the student's skill level. Two transmitters must be connected by an optional trainer cord, and the instructor's transmitter should be programmed for trainer operation, as described below. When the Instructor activates the trainer switch, the student has control of the aircraft (if MIX or FUNC mode is turned on, the Instructor can make corrections while the student has control). When the switch is released the Instructor regains control. This is very useful if the student gets the aircraft into an undesirable situation.

You can select the channel input data from the student transmitter as either "FUNC" or "MIX" mode. These options make it easier to use a variety of receivers, transmitters, etc.

It is also possible to use the virtual channel (VC) at “FUNC” or “MIX” mode or to use the trainer system with flying wing airplanes. When using T8FGS as the student transmitter, the trainer function is not used.

(*1) You can select the operation mode for each channel. (NORM/MIX/FUNC/OFF)

NOTE: This trainer system can be used in the

following manner; 1. With the T8FGS transmitter and a conventional

transmitter, if the channel order is different, it is necessary to match the channel order before using this function. You can select the channel of input data from student's transmitter in the "FUNC" or "MIX" mode. 2. When the T8FGS is used as the instructor’s

transmitter, set the modulation mode of the student’s transmitter to PPM. If being used as the student, T8FGS can be connected to the instructor's transmitter which the PPM mode as the student's modulation mode is required. T8FGS always sends PPM mode signal from the trainer jack. 3. Be sure that all channels work correctly in both transmitters before flying.



### T8FGS/T12FG special trainer cable

Use the T8FGS/T12FG special trainer cable (FUTM4405) when using the T8FGS or T12FG transmitter at the trainer function instructor side. Operation may not be normal with a conventional trainer cable.

*If the T8FGS or T12FG transmitter is used as the student transmitter when the instructor transmitter is not a T8FGS or T12FG, a conventional trainer cable may be used.
Instructor Student Trainer cable

T8FGS, T12FG, FX-20 T4EX, T6EX, T7C, T9C, T10C T12FG special trainer cable T8FGS, T12FG, T12Z, T14MZ, FX-40, FX-20 Conventional trainer cable (Rect. - Rect.)

### *The direction that the T8FGS/T12FG special trainer cable connects is fixed. Connect the instructor cable adapter connector of the cable to the instructor T8FGS or T12FG and connect the student connector to the student transmitter. If the cable is connected in reverse, the student's transmitter power will not be turned on even if the instructor side power is set to ON. *If the instructor side T8FGS or T12FG trainer function is not enabled, the student's power will not be turned ON even if the connection direction is correct.

# SWASH Swash AFR and linkage correction function. (helicopter only, except swash type H-1)



### Neutral Point

At your linkages, if the servo horn deviates from a perpendicular position at neutral, the linkage compensation functions in this menu may not compensate effectively. To correct this use the Neutral Point function. This will move the neutral point of the servos to the actual perpendicular position. However, this adjustment changes only the axis point of the compensation functions in this menu, and does not affect the neutral position of other functions.

Swash AFR Swash AFR function reduces, increases, or reverses the rate (travel) of the aileron, elevator and collective pitch functions, by adjusting or reversing the motion of all servos involved in that function, only when using that function. Mixing RateThis mixing is used to compensate the swashplate as necessary during specific control inputs.

Neutral point setting procedure The neutral point becomes the correction standard point.

*Adjusting the servo horn so that the neutral point is near the

50% position makes the mixing amount small. 1. Neutral point setting

Move the cursor to the [POS] item and hold the pitch operation so that the servo horn is at a right angle to the linkage rod and Touch the RTN button for one second. This value indicates the servo's neutral position.

After reading the neutral point, use the other correction functions to make further adjustments. 

### The following compensation mixing is possible; PIT to AIL, PIT to ELE, AIL to PIT, ELE to AIL,and ELE to PIT (HR3 mode.) It adjusts the swashplate to for proper operation of each control using the corresponding compensation mixing.
Linkage Compensation This compensation mixing is used to correct the swash-plate for pitch control at low pitch and high pitch. Speed Compensation

This function is used to cancel the reaction that is generated by the difference in the movements of each servo when the swash-plate moves.

Subtrim Subtrim for aileron, elevator and pitch can be set during swash setting. Pitch adjustment function

High, neutral and low pitch fixed outputs can be used while adjusting the pitch.

Swash AFR setting procedure

The swash AFR function makes adjustments so that the servos travel the specified amount by [AIL], [ELE], and [PIT] operation.
1. Move the cursor to the function you want to

adjust and touch the RTN button to switch to the data input mode. 2. Adjust the AFR rate by scrolling the touch

sensor. Initial value: +50% Adjustment range: -100%~+100%

*When the RTN button is touched for one second, the AFR rate is reset to the initial value. Touch the RTN button to end adjustment and return to the cursor mode. ● Select [SWASH] in the Linkage menu and access

# AILEVATOR [Corresponding model type]: Airplane/glider, Ailevator (Effective only when 2 servos used at the elevators) 

### This function improves the performance of the roll axis by operating the elevators as ailerons.

Ailevator is where each elevator in a standard (conventional) or v-tail moves independently, like ailerons on a wing. In addition to each elevator side moving up and down together, each side moves in opposite directions when moving as an Ailevator. On a V-tail, this is also known as a Ruddervator, as they can serve the same purpose. Typically, both Ailevator and ailerons are coupled together to maximize roll performance, especially on larger wingspan planes.

Note: Select Ailevator as the Model Type at the Model Type screen. This changes the output channel. Check the Function menu.

RUDDER 2 Winglet at Flying wing 

### ( ) 

# WINGLET [Corresponding model type]: Airplane/glider, Flying wing only



### This function adjusts the left and right rudder angles of airplanes with winglets.

Winglets are used to improve the efficiency of aircraft by lowering the lift-induced drag caused by wingtip vortices. The winglet is a vertical or angled extension located at the tip of each wing.

Winglets work by increasing the effective aspect ratio wing without adding greatly to the structural stress and hence necessary weight of its structure - an extension of wing span would also permit lowering of induced drag, though it would cause parasitic drag and would require boosting the strength of the wing and hence its weight. There would come a point at which no overall useful gains would be made. A winglet helps to solve this by effectively increasing the aspect ratio without adding to the span of the wing.

The operation speed can be set for two ranges, slow speed flight and high speed flight (Speed 1/Speed 2). This function can also be operated as a safety function by programming it to a switch.

● The In side and Out side operating speeds can

be adjusted independently in 2 ranges (Speed 1/ Speed 2).

● The boundary between the 2 ranges can be set.

(From Speed 1 to Speed 2)

# TIMER ST1/ST2 Timer setting



### The Timer function may be set for any desired time, i.e. engine run time, specified times for competitions, etc. Two independent timers are provided for your use. The timers are stored independently with each model, meaning that when you switch between model setups, the timer associated with the new model is brought up automatically.

The timers may be set to start and stop from the motion of any switch or stick. You may set the ON and OFF directions freely. Each timer has a capacity of up to 59 minutes 59 seconds. Each timer may be set for count-down (DOWN mode) or count up (UP mode) operation with a target time or for count up to 99 hours 59 minutes (HOUR mode).

If a target time is set and the timer reaches the set time, a buzzer sound for each count is generated. Countdown timers sound one short beep during the last twenty seconds and two short beeps during the last ten seconds before reaching the target, then a long tone at the target time, and continue counting with displaying a minus (-) sign. Count-up timers also beep the last twenty and ten seconds, beep the target time, and keep counting upwards until shut down.

A mode which sounds an alarm each minute of the time remaining up to the timer alarm time can be selected.
The HOUR mode is convenient when used in engine maintenance period and other long-term
measurements.

* When the HOUR mode is set, "xx (hour): xx (minute)" is displayed on the count time display. Seconds are not displayed.

* When the HOUR mode is set, ":" blinks each second during timer operation.

* When the HOUR mode is set, the alarm function is inhibited.
