It connects with the 
battery for power, etc.
External voltage input 
cable of an option
 is 
used. The voltage of 
the battery can be 
displayed with a 
transmitter. 

Usage precaution

• Analog servos cannot be used with the 

R7008SB in the FASSTest 12CH mode.

• The R7008SB receiver can only be used 

with FASSTest capable transmitters.

• Don't connect to Extra Voltage before turn-

ing 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 R7008SB receiver should be protect-

ed 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

 

Do not cut or bundle the receiver antenna 
wire.  

 

Do not 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 R7008SB 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 exposed antenna should be 
secured so that it cannot move around or back 
inside of your aircraft. 

S.BUS2 precaution

DANGER

 

Don't connect a connec-

tor, as shown in a before 
figure.

• It will short-circuit, if it connected 

in this way. A short circuit across 
the battery terminals may cause 
abnormal heating, fire and burns.

WARNING

 

Only S.BUS2 capable devices may be connected 

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

Receiver

R7008SB

Thank you for purchasing a Futaba 

R7008SB FASSTest-

2.4GHz

 compatible receiver. The 

R7008SB

 receiver features bi-

directional communication with a 

FASSTest

 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.
