Usage precaution

• Futaba T-FHSS Air system does not work with current Futaba T-

FHSS / S-FHSS / FHSS / FASST / FASSTest system.

• The R3008SB receiver can only be used with T-FHSS Air capable

transmitters.

• Don't connect Extra Voltage before turning on a receiver.

WARNING

Changes or modification not expressly approved by the party

responsible for compliance could void the user’s authority to operate the

equipment.

The R3008SB receiver should be protected from vibration by foam

rubber, Velcro or similar mounting methods. Protect from moisture.

Keep away from conductive materials to avoid short circuits.

Antenna installation precaution

Don't cut or bundle the receiver antenna wire.

Don't bend the coaxial cable. It causes damage.

The antennas must be mounted in such a way to assure they are

strain relieved.

Keep the antenna as far away from the motor, ESC and other noise

sources as you possibly can.

Be sure that the two antennas are placed at 90 degrees to each other.

• The R3008SB has two antennas. In order to maximize signal reception

and promote safe modeling Futaba has adopted a diversity antenna

system. This allows the receiver to obtain RF signals on both antennas

and ﬂy problem-free.

WARNING

You must leave 30mm at the tip of the antenna fully exposed. The ex-

posed antenna should be secured so that it cannot move around or back

inside of your aircraft.

S.BUS2 precaution

DANGER

Don't connect a connector, as shown right.

• It will be a short-circuit, if it connected in

this way. A short circuit across the battery

terminals may cause abnormal heat, fire

and burning.

The Futaba R3008SB is a T-FHSS Air-2.4GHz bidirectional communication system receiver, designed for use with compatible Futaba T-FHSS Air transmitters. It features an S.BUS2 port for telemetry sensors, an S.BUS output port, and 8 conventional PWM output ports.

Function Description:

The R3008SB receiver facilitates two-way communication with a T-FHSS Air-2.4GHz Futaba transmitter. The S.BUS2 port allows for the connection of various telemetry sensors, enabling data to be displayed on the transmitter. It also provides standard PWM outputs for conventional servos and an S.BUS output for S.BUS compatible devices. The receiver incorporates a dual antenna diversity system to maximize signal reception and ensure reliable operation.

Important Technical Specifications:

System: T-FHSS Air-2.4GHz system/S.BUS2 and S.BUS port and 8 channels for conventional system receiver.
Antenna: Dual antenna diversity.
Size: 0.98 x 1.86 x 0.56 inches (24.9 x 47.3 x 14.3 mm).
Weight: 0.36 oz. (10.1g).
Power Requirement: 4.8V to 7.4V.
Battery F/S Voltage: Configured with a transmitter.
Extra Voltage Port: 0 ~ 70V DC.
Channel Modes: Supports multiple channel allocations (Mode A, B, C, D) which can be configured by the user. Default is Mode B.

Usage Features:

Compatibility: Works exclusively with Futaba T-FHSS Air capable transmitters. It is not compatible with current Futaba T-FHSS, S-FHSS, FHSS, FASST, or FASSTest systems.
Easy Link ID: Allows linking to a compatible transmitter without pressing a link button on the receiver. The process involves bringing the transmitter and receiver close, turning on the transmitter in linking mode, then turning on the receiver. Linking is confirmed when the receiver's LED changes from blinking red to solid green.
S.BUS2: Extends S.BUS functionality with bidirectional communication, primarily for connecting telemetry sensors. Only S.BUS2 capable devices should be connected to this port; standard S.BUS servos and gyros are not compatible with the S.BUS2 port.
S.BUS: A data communication system that transmits control signals from the receiver to S.BUS compatible servos, gyros, or other devices. Multiple S.BUS devices can be connected to the same signal line, with each device executing commands for its own set channel. S.BUS servo channels can be set using an SBC-1 channel changer, CIU-2 USB serial interface, or programming software in the T10J transmitter.
Channel Mode Switching: The receiver's channel allocation can be changed by a specific sequence of button presses on the Mode switch while the transmitter is off. The LED indicates the current set status through flashing patterns.
Antenna Installation: Features two antennas that should be placed at 90 degrees to each other for optimal signal reception. For carbon fuselages, 30mm of the antenna tip must be fully exposed and secured to prevent movement.
LED Indication: The LED provides status feedback: Off (no signal reception), Solid (receiving signals), Alternate blink (unrecoverable error).
Extra Voltage Port: Allows connection of a battery for power or external voltage input cables from options, enabling the battery voltage to be displayed on the transmitter.

Maintenance Features:

Protection: The receiver should be protected from vibration using foam rubber, Velcro, or similar methods, and kept away from moisture and conductive materials to prevent short circuits.
Antenna Care: Do not cut or bundle the receiver antenna wire, and avoid bending the coaxial cable as it can cause damage. Antennas must be mounted with strain relief. Keep antennas as far as possible from motors, ESCs, and other noise sources.
Power-up Sequence: Always power up the transmitter first, followed by the receiver. When linking, ensure the motor's main wire is not connected and the engine is not operating to prevent serious injury.
S.BUS Servo Handling: Do not insert or remove servo connectors while the receiver power is ON, as S.BUS connected servos can be erroneously recognized and stop.
FCC Compliance: The device complies with FCC Rules Part 15. Users are cautioned against unauthorized changes or modifications to the device, which could void their authority to operate the equipment. The device must accept any interference received and must not cause harmful interference. It complies with FCC radiation exposure limits for an uncontrolled environment and should not be co-located with another transmitting device.
