Thank you for purchasing Futaba's
SBS-01RB brushless motor RPM
sensor. By combining the SBS-01RB
with a telemetry receiver, the RPM of
a drive use brushless motor mounted
in a model can be transmitted from
the receiver to the transmitter. You
can monitor the RPM of the model
during flight (running). Please read this
manual thoroughly to maximize your
enjoyment and ensure proper sensing
performance. We also encourage
you to retain the manual for future
reference.
WARNING
1M23N26727
To utilize the SBS-01RB sensor,
connect it to the S.BUS2 port of the
Futaba telemetry enabled receivers.
Telemetry RPM Sensor
(Brushless type)
■ The SBS-01RB will not function properly
if connected to an S.BUS port or other
channel ports.

Instruction Manual
Do not use the SBS-01RB with
anything other than an electric
R/C model.
Ensure that the unit is mounted in
a n a r e a t h a t w i l l e l i m i n a t e
exposure to fuel, water and vibration.

Brushless Motor
■ As with any electronic components,
proper precautions are urged to prolong
the life and increase the performance of
the SBS-01RB.
Use : Brushless motor RPM Sensor
Length : 475mm (18.7")
Weight : 3.8g (0.134oz)
Voltage : DC3.7 ～ 7.4V
Range : 360 ～ 300,000RPM
To ensure that the SBS-01RB is
functioning as desired, please test
accordingly.
■ Do not use until inspection is complete.
Allow a slight amount of slack in
the SBS-01RB cables and fasten
them at a suitable location to prevent
any damage from vibration.
The RPM of a brushless motor can
be viewed on your transmitter
without removing the motor's
magnet using only a wiring
connection (soldering is nec-
essary).
●The SBS-01RB can be used
with Futaba telemetry transmit-
ters and receivers and drive use
brushless motors.

1/2 number of poles × gear ratio =
Input this value at the transmitter
gear ratio.
(Example)
For 14 poles with a gear ratio of 6
For a 14-pole motor → gear ratio 7.00
Number of poles of aircraft motor
When you want to display the motor RPM of
a car use motor, set the gear ratio to 1.00
*
Each aircraft use brushless motor
has a different number of poles. The
number of poles of the motor used
must be checked against the motor
instruction manual and entered at the
telemetry RPM setup screen of the
transmitter. (Car use motors do not
have to be set.) When the transmitter
does not have a number of poles input
item, input 1/2 the value of the number
of poles at the gear ratio.
Helicopter rotor RPM
7（1/2 number of poles）× 6 = 42
Input 42.00 at the gear ratio.
When you want to display the RPM of
a helicopter rotor or of the propeller of an
aircraft with its gear down instead of motor
RPM, make the following settings.
The upper limit of the gear ratio of the
T10J is 30.00. If this is insufficient, the
gear ratio can be updated (maximum
99.99) by a Futaba Support Center.
Please inquire.

For transmitter setting, select magnet type.
