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 cover/hold the built-in antenna part of T8J-2.4G transmitter by your hand during 


" Do not put any conductive plate/sticker on the antenna part. Otherwise, the operating range 

may become shorter.

 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 

				
				

 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.

charges with an exclusive charger(LBC-4E5).

INSTALLATION AND REMOVAL OF THE TRANSMITTER BATTERY 

The T8J transmitter is designed to work with either 

four (4) AA alkaline dry cell batteries, or HT5F1700B/

FT2F2100B battery pack, both available separately. 

The transmitter batteries used are a matter of personal 

preference. AA Alkaline batteries are available at any 

local hobby shop, grocery store, etc. A battery pack 

will need to be purchased from a hobby shop.

Remove the battery BOX if you choose to use the 

optional HT5F1700B/FT2F2100B battery pack, 

which can be recharged from the transmitter.

And "BATT TYPE" in a PARAMETER is 

changed into "5CELL" in the procedure of P.33.

￼ WARNING

￺ Do not connect any other chargers except 

the special charger to this charging 

connector.

*If you take out the Ni-MH battery HT5F1700B from the 

transmitter, you can use the optional quick charger CR2000 corresponding to Ni-MH battery. 

￼ WARNING

￸ Be careful not to drop the battery.

￺ Never disconnect the battery connector 

from the T8J transmitter after turning off 

the power until the screen is completely 

blank and the transmitter has shut down 

completely. 

* Internal devices such as memories may be damaged.

* If there is any problem, the message "Backup Error" will 

be shown the next time when you turn on the power of 

the transmitter. Do not use the transmitter as it is. Send it 

to the Futaba Service Center.

According to the description of the battery to be used and its 

exclusive charger, please use it after carrying out full charge.

We recommend charging the batteries with the charger 

supplied with your system. Note that the use of a fast charger 

may damage the batteries by overheating and dramatically 

reduce their lifetime. 

When HT5F1700B is chosen, HBC-3A (4) is recommended.

When charging FT2F2100B, Please make sure to remove the 

battery from the system to charge it. Charger for this battery 

is recommended to use LBC-4E5.

CHARGING THE BATTERIES (When the rechargeable battery option is used) 

Charging Your System’s Batteries 

1. Connect the transmitter charging jack and batteries to the transmitter and receiver connectors of the 

charger. 

2. Plug the charger into a wall socket. 

3. Check that the charger LED lights.

and/or receiver battery packs. These are included to serve only as general guidelines, and are not intended 

to replace or supersede the information provided by the battery and/or charger manufacturer. For complete 

information, please refer to the instructions that are included with the battery pack(s) and/or chargers that 

accompany the products purchased.

 Do not allow children to charge battery packs without adult supervision.

 Do not charge battery packs that have been damaged in any way. We strongly suggest frequent inspection 

of the battery packs to ensure that no damage has occurred. 

 Do not to allow batteries to overheat! If overheated, disconnect the battery from the charger immediately 

and allow to cool.

 
	Y

 Do not deep cycle NiMH batteries as permanent damage could result.

 Never charge batteries on a surface that may become hot, or may be impacted by the heat.

 Immediately end the charging procedure if either the batteries or charger itself become overly hot. 

 NiMH cells do not exhibit the “memory effect” like NiCd cells, so little cycling is needed. Store NiMH 

packs with some voltage remaining on the cells (refer to battery supplier).

 NiMH cells have a self-discharge rate of approximately 20-25% (compared to 15% for NiCd batteries). It is 

important to recharge NiMH batteries immediately prior to use.

 Never connect the battery in reverse. Reverse connection will cause the battery to overheat or will damage 

the inside of the charger.

 Do not add an additional charge after charging.

 Never charge with a current exceeding the nominal capacity (lC) of the rechargeable battery. 

 If a battery is charged with a current exceeding 1C, the battery will overheat and deteriorate.

 Do not connect two battery packs or more to one output terminal.

 Avoid extremely cold and hot places and the direct sunlight when you charge batteries. 

 It is recommended to perform charging within the 10 ~ 30°C (50-85°F) range. Otherwise, it may cause 

abnormal charging and overheat.

We have installed a special “Power Down Mode” in the T8J in order to perform an operational ground range 

check. During this mode, the RF power is reduced in order to test the operational range of the T8J. 

To activate the Power Down Mode and Perform A Range Check:

1) To activate the “Power Down Mode” please hold down the JOG KEY and then turn the transmitter switch 

on. A power mode screen comes out. JOG KEY is pushed where Power Down is chosen. When this mode is 

active the Purple LED on the Lighting front of the transmitter will provide users with an audible and visual 

indication that the transmitter is in the “Power Down Mode”. 

Audibly, the transmitter will beep one time every three seconds. Visually, the LCD screen will display 

“POWER DOWN MODE”. The words “POWER DOWN MODE” will blink as an additional reminder that 

the transmitter is in the “Power Down Mode”.

2) With the “Power Down Mode” activated, walk away from the model while simultaneously operating the

3) If everything operates correctly, return to the model. Push END KEY and complete power down mode. 

Set the transmitter in a safe yet accessible location so it will be within reach after starting the engine. Be 

certain the throttle stick is all the way down, and then start the engine. Perform another range check with 

your assistant holding the model and the engine running at various speeds.

These receivers incorporate two separate antennas 

into their design which enables them to receive 

the radio frequency transmission at two different 

locations.

 Futaba's dual antenna diversity then seamlessly selects the best signal reception between these antennas to 

ensure that there is no loss of signal.

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.

Please refer the table below for LED status vs

LINK PROCEDURE (T8J transmitter/R2008SB):

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 R2008SB receivers, this procedure is necessary; otherwise the 

receiver will not work. 

1. Bring the transmitter and the receiver close to each other, within 20 inches (half meter).

2. Turn on the transmitter. 

3. Turn on the receiver. 

4. Press and hold the Link switch more than two (2) seconds. When the link is complete, the LED in the 

receiver changes to solid green. When the ID cannot be read due to the surrounding environment, try 

reading it with the transmitter and receiver touched.

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.

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.

S.BUS INSTALLATION

This set uses the S.BUS system. The wiring is as simplified and clean mounting as possible, even with 

models that use a large number of servos. In addition, the wings can be quickly installed to the fuselage 

without any erroneous wiring by the use of only one simple wire, even when there are a large number of 

servos used.

	Z			

	!		

 Do not insert or remove the servo connector while the receiver power is ON.

Since the S.BUS servo switches the operation mode automatically according to the type of signal (S.BUS signal/PWM signal) from the receiver, if the 

connector is inserted or removed while the power is ON, an S.BUS connected servo will be erroneously recognized and may stop.

 Please make sure that you use a battery that can deliver enough capacity for the number and kind of 

servos used. Alkaline batteries cannot be used.

WARNING & ERROR DISPLAYS 

An alarm or error indication may appear on the display of your transmitter for a number of reasons, including 

when the transmitter power switch is turned on, when the battery voltage is low, and several others. Each 

display has a unique sound associated with it, as described below.

LOW BATTERY ERROR: Warning sound: Continuous beep until transmitter is powered off.

The LOW BATTERY warning is displayed when the transmitter battery voltage drops below 4.1V. (5CELL mode 

4.9V)

Land your model as soon as possible before loss of control due to a dead 

battery. 

MIXING ALERT WARNING: Warning sound: Several times of beeps (repeated until problem resolved or 

overridden) 

The MIXING ALERT warning is displayed to alert you whenever you turn on 

the transmitter with any of the mixing switches active. This warning will 

disappear when the offending switch or control is deactivated. Switches for 

which warnings will be issued at power-up are listed below. Throttle cut, 

idle-down, snap roll, airbrake, throttle-stick and condition. If turning a switch OFF does not stop the 

mixing warning: When the warning does not stop even when the mixing switch indicated by the 

warning display on the screen is turned off, the functions described previously probably use the same 

switch and the OFF direction setting is reversed. In short, one of the mixings described above is not in 

the OFF state. In this case, reset the warning display by pressing both + / - KEY at the same time. 

Next, change one of the switch settings of the duplicated mixings.

*If "ESC mode" is chosen by "THR.CUT", a THR CUT will not start warning.

BACKUP ERROR: Warning sound: Several times of beeps (repeated continuously)

The BACKUP ERROR warning occurs when the transmitter memory is lost for any reason. If this occurs, all of 

the data will be reset when the power is turned on again.

this feature is changed to ON position (CH5+ or CH5-). Snap rolls will not be commanded even if the snap roll 

SWITCH is turned on with the gear SWITCH in this position. When the landing gear SWITCH is moved to the 

opposite position, snap rolls may be commanded. 

FREE: the safety mechanism is completely turned off. Snaps can be commanded regardless of the gear SWITCH 

POSITION. 

Note: The location of the safety switch always follows channel 5. If channel 5 is reassigned to switch C, for 

example, switch C is now the safety. If channel 5 is nulled, the safety function will not be available.
