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.

Battery Care and Precautions

~ ! 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.

RADIO INSTALLATION

Follow these guidelines to properly mount the servos, receiver and battery.

• $ Z 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.

• ^ _ „ 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.

• rubber grommets.	Servo	Rubber	Servo	Rubber
Do not over tighten the screws. No part of the servo casing		grommet		grommet
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.

• Œ ! ^• ` # ‡_ ! ‡Y The numbers indicate how many degrees each arm is “off” from 90 degrees to correct for minute manufacturing deviations from servo to servo.

• • K the arm that will be perpendicular to the pushrod when placed on the servo.

• Z 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.

• ] 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.

• " ƒ 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.

IMPORTANT: Since the 2.4GHz have different characteristics than that of the conventional 27MHz and 72MHz frequencies, please read this section carefully to maximize your enjoyment of the 2.4GHz system.

Receiver's Antenna Installation:

• \ †`||[;~ appearance from the standard Futaba receiver. 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.

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.

• ! Z 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

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.

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.

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.

• ;Y ˆ;;™ ˆ;; „ Z 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.

Please refer the table below for LED status vs receiver's condition.

		LED Indication
Green	Red	Status
Off	Solid	No signal reception
Solid	Off	Receiving signals
Blink	Off	Receiving signals but ID is unmatched
Alternate blink		Unrecoverable error (Memory, etc.)

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.

WARNING

• ¤ 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.

# : all programming has been erased and is not available. Return your transmitter to Futaba for service.
