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. 
<Introduction> 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 charge, 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 <Introduction>

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.

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.

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.

[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.

<Receiver and Servo Installation> 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. 

Servo

Rubber

grommet Servo

Rubber

grommet

• Note the small numbers (1, 2, 3, 4) molded into 

each arm on the Futaba 4-arm servo arms. The 

numbers indicate how many degrees each arm 

is “off” from 90 degrees to correct for minute 

manufacturing deviations from servo to servo. 

• To center the servos, connect them to the receiver 

and turn on the transmitter and receiver. Center 

the trims on the transmitter, then find the arm that 

will be perpendicular to the pushrod when placed 

on the servo. 

• After the servos are installed, operate each servo 

over its full travel and check that the pushrods and 

servo arms do not bind or contact each other. Also 

make sure the controls do not require excess force 

to operate. If there is an objectionable buzzing 

sound coming from a servo, there is probably too 

much resistance in the control. Find and correct 

the problem. Even if there is no servo damage, 

excess battery drain will result. 

• Use the mounting plate from the receiver 

on/off switch as a template for the cutout and 

screw holes. Mount the switch on the side of the 

fuselage opposite the engine exhaust, and where 

it 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.

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.

<Model Basic Setting Procedure> 35

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 <Model Basic Setting Procedure>

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.
<Model Basic Setting Procedure> 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 conditions 

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 <Model Basic Setting Procedure>

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 +5o~6o.

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 -7o~+12o as standard.

●Pitch curve (Idle up 2)

The high side pitch setting is less than idle up 1. 

The standard is +8o.

●Pitch curve (Hold)

At auto rotation, use the maximum pitch at both 

the high and low sides.

[Pitch angle setting example]

Throttle hold: -7o~+12o

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,.
<Model Basic Setting Procedure> 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 540o 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 0o.

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 <Model Basic Setting Procedure>

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.

transmitter’s internal memory or an SD card (32MB2GB). Remember that up to 20 model memories are 

available in the transmitter.

The name of the model stored in the transmitter and 

the SD card may be changed. This can be very useful 

to tell different models settings apart. Each model name 

can be as long as 10 characters, and the model name 

always appears in the display screen.

The Copy function is used to copy parameters, 

settings, etc. from one model data into a second 

memory. It may be used for getting a head-start on 

setting up models with almost the same settings (only 

differences need to be modified, instead of entering the 

complete model from scratch). Also, this function may

FAIL SAFE Sets the servos operating position when transmitter signals can no 

longer be received or when the receiver battery voltage drops.

(The display screen is an example. The 

screen depends on the model type.)

The Failsafe function may be used to set up 

positions that the servos move to in the case of 

radio interference.

You may set either of two positions for each 

channel: Hold, where the servo maintains its last 

commanded position, or Failsafe, where each 

servo moves to a predetermined position. You may 

choose either mode for each channel. (FASST 7CH 

mode: CH3 only)

The T8FGS system also provides you with an 

advanced battery monitoring function that warns 

you when the receiver battery has only a little 

power remaining. In this case, each servo is moved 

to the defined failsafe position. (FASST 7CH 

mode: CH3 only) The battery failsafe may be 

released by operating a predefined control on the

when receiver battery voltage becomes low.

WARNING

 For safety, always set the fail safe functions.

●Especially set the throttle channel fail safe function so that 

the servo moves to the maximum slow side for airplanes and 

to the slow side from the hovering position for helicopters. 

Crashing of the model at full high when normal radio waves 

cannot be received due to interference, etc., is very dangerous.

●If the battery fail safe is reset by throttle stick, it may be mistaken 

for an engine malfunction and will be reset at throttle slow and the 

model will continue to fly. If you have any doubts, immediately 

land.

Battery fail safe setting procedure

Battery fail safe can be set for each channel 

by the same method as the fail safe setting 

procedure. Select and set the "B.F/S" item.

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 Rate

This 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.

Mixing rate setting procedure

The HR3 swash-plate type will be used as an 

example to describe mixing rate setting. The mixing 

used in other swash modes may be different, 

however, the setting procedure is the same.

*Set the throttle stick to the preset neutral point. Adjust the 

length of the linkage rod so that the swash plate is horizontal 

at this position.

*The sub-trim function can be used to make small 

adjustments.

*Adjust so that the pitch curve is a straight line and the 

helicopter achieves maximum pitch.

*Move the cursor to the item you want to adjust and touch 

the RTN button to switch to the data input mode. Touch 

the RTN button to end adjustment and return to the cursor 

mode.

1. Adjusting the aileron operation [AIL to PIT]

Adjust the AIL to PIT rate so there is no binding 

in the elevator or pitch movement when the 

aileron stick is moved to the left and right.

*Adjust by scrolling the touch sensor.

*The left and right sides can be adjusted individually.

2. Adjusting the elevator operation [ELE to AIL]/

[ELE to PIT]

Adjust the ELE to AIL and ELE to PIT rates so 

there is no binding in the aileron or pitch 

movement when the elevator stick is moved 

up and down.

*Adjust by scrolling the touch sensor.

*The up and down sides can be adjusted individually.

3. Adjusting the pitch operation [PIT to AIL][PIT 

to ELE]

Adjust the PIT to AIL and PIT to ELE rates so 

that the swash plate moves to the level/

horizontal position when the throttle stick was 

moved to maximum low and full high.

*Adjust by scrolling the touch sensor.

*The slow and high sides can be adjusted individually.

Linkage compensation setting procedure

*Prior to utilizing the linkage compensation settings, it is 

important to adjust the mixing rate settings.

*Linkage compensation overrides interference from the 

aileron operation with the elevator or elevator operation 

with the aileron at collective pitch control for low pitch and 

high pitch.

*When making the following setting, Move the cursor to the 

item you want to set and touch the RTN button to switch 

to the data input mode. Touch the RTN button to end 

adjustment and return to the cursor mode.

1. Compensating aileron input [AIL]

Set the throttle to the lowest position. Move 

the aileron stick to the left and right and 

adjust the aileron compensation amount 

so that interference in the elevator or pitch 

direction is minimal.

*Adjust by scrolling the touch sensor.

*The left and right sides can be adjusted individually.

*If the interference increases when the compensation amount 

was increased, make adjustments with the compensation 

direction [DIR.] as "-".

2. Compensating elevator input [ELE]

Adjust the elevator compensation amount 

so that the aileron or pitch direction 

interference when the elevator stick was 

moved up and down is minimal.

3. Repeat steps 1 and 2 above, perform aileron 

and elevator compensation similarly at full 

throttle.

Speed compensation setting procedure

1. Move the cursor to the "SPEED" item and 

touch the RTN button to switch to the data 

input mode.

2. Set the throttle stick to the neutral point 

position. Quickly move the elevator stick and

PROG. MIX Program mixing which can be freely customized. Up to five mixings 

can be used for each model. [All model types]

Programmable mixing may be used to correct 

undesired tendencies of the aircraft, and it may also be 

used for unusual control configurations. Mixing means 

that the motion of a command channel, called the 

"master," is added to the motion of the mixed channel, 

called "slave."

You may choose to have the Master's trim added to 

the Slave channel response ("Trim" setting). The mixing 

curve (Linear/5-point) can be changed. You may select 

Mixing ON/OFF switch, control or you may choose to 

have mixing remaining on all the time.

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 1

Winglet ( ) at Flying wing

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.

MOTOR [Corresponding model type]: Airplane/glider, general

This function lets you set the speed when the 

motor of an F5B or other EP glider is started via 

a switch. 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)

● The operational speed can only be activated at

the initial operation. However, operation can be 

repeated by setting the switch to OFF before the 

operation is finished. When you want to reset one

time operation, set the ACT/INH item to [INH] and 

then reset it to [ON]. 

● The motor channel is controlled by SW-G. (Glider:

Initial setting) When changing the switch or stick 

which controls the motor, first change Function of

the Linkage menu.

● If the Model Type selected is Airplane, the MOTOR

function is changed from INH to ON and it is not 

assigned to another channel, the changes from 

the throttle channel to the motor channel are 

enabled. 

Note: Initial setting does not assign a motor 

channel according to the model type. Prior to 

assigning the motor channel, find an unused 

channel. Then, use the Function menu of the

Pitch Trim (Hovering pitch, high pitch, low pitch)

[Hovering pitch trim setting]

Hovering pitch trim

The Hovering Pitch trim function trims the pitch 

near the hovering point. Normally, it is used with 

the hovering condition. The hovering pitch can be 

fine tuned for changes in rotor speed accompanying 

changes in temperature, humidity, and other flight 

conditions. Adjust the hovering pitch so that 

rotor speed is constant. This function can be used 

together with the Hovering Throttle Trim function 

for more precise operation.

Setting method

● Set the function to ACT [ON]. (initial setting)

● Select the adjustment knob.

Selection example: LD (initial setting)

● The trim operation mode (Mode: CTRM/

NORM) can be selected.

CTRM mode: Maximum amount of change 

near center by center trim operation 

(recommended)

NORM mode: N o r m a l t r i m ( p a r a l l e l

THR CURVE/THROTTLE HOVER TRIM

Throttle Curve

Throttle curve function adjusts the throttle 

operation curve for each condition to optimize the 

engine speed to throttle stick movement.

The Throttle Hover function trims the throttle 

near the hovering point. Normally, use it with 

hovering conditions. Changes in rotor speed 

accompanying changes in the temperature, 

humidity, and other flight conditions can be 

trimmed. Adjust the throttle so that rotor rotation is 

most stable. More precise trimming is also possible 

by using this function along with the Hover Pitch 

function.

PIT to RUD mixing (Revolution mixing)

Use this mix when you want to suppress the 

reaction torque generated by main rotor pitch and 

speed changes during pitch operation. Adjust so 

that the nose does not move in the rudder direction.

<Normal condition mixing curve>

The mixing curve rate should be started 

using smaller values.

For a rotor with a clockwise operation 

direction, when pitch was input at the plus 

side, set these parameters so that mixing 

is in the clockwise direction. First, trim at 

hovering and then adjust the neutral 

position.

1. Adjustment between slow and hovering

Repeatedly hover from take off and land 

at a constant rate matched to your own 

rhythm. Then adjust the pitch so that the 

nose of the helicopter remains steady 

when the throttle is raised and lowered.

2. Throttle high side (climbing and diving from 

hovering)

Repeat climbing and diving from hovering 

at a constant rate matched to your own 

rhythm and adjust the pitch so that the nose 

does not deflect when the throttle is raised 

and lowered.

Note: When a GY Series or other heading hold 

gyro is used, since correction is performed by 

the gyro, this mix is not utilized. If this function 

is used when the gyro operation mode is the

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.
