T-FHSS Air-2.4GHz system/S.BUS2 and S.BUS port and 8 channels for 

conventional system receiver
• Dual antenna diversity

• Size: 0.98 x 1.86 x 0.56 in. (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: It sets up with a transmitter

• Extra Voltage port: 0 ～ 70V DC

* Be sure that when using ESCs regulated output the capacity of the ESC must 

meet your usage condition.

Thank you for purchasing a Futaba R3008SB T-FHSS Air-2.4GHz compatible receiver. The R3008SB receiver features bi-directional communication 

with a T-FHSS Air-2.4GHz Futaba transmitter using the S.BUS2 port.  Using the S.BUS2 port an impressive array of telemetry sensors may be utilized.  

It also includes both standard PWM output ports and S.BUS output ports.

• 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.

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.

 

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.

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. 

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.

Don't connect servo for conventional system to S.BUS/S.BUS2 port.

• Digital servo for conventional system

→ It does not operate.

• Analog

 servo → It may cause abnormal heat, fire and burning.

Only S.BUS2 capable devices may be connected the S.BUS2 port.  

Standard S.BUS servos and gyros should not be connected the S.BUS2 
port.

Do not insert either a switch 

or battery in this manner.
