Instruction Manual

RPM

Brushless Motor

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 nec­essary).

●The SBS-01RB can be used
with Futaba telemetry transmit­ters and receivers and drive use
brushless motors.

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 ight (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

To utilize the SBS-01RB sensor,
connect it to the S.BUS2 port of the

Futaba telemetry enabled receivers.

■ The SBS-01RB will not function properly

if co nnected t o an S.BUS port or other
channel ports.

Do not use the SBS-01RB with
anything other than an electric

R/C model.

Ensure that the unit is mounted in
an area that will eliminate

exposure to fuel, water and vibration.

■ As w it h any ele ctr oni c c om ponen ts,

proper precautions are urged to prolong
the life and increase the performance of
the SBS-01RB.

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

any damage from vibration.

Slot Number Setup

Please note that the proper default
slot for this accessory is number two.
Information on how to change the
slot assignment is included in the
transmitter's manual.

Wiring

Brushless motor

Of the 3 wires of the motor, any 2 are solder­connected. Any of the 3 wires can be used.

Number of poles of aircraft motor

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.
