Instruction Manual
Thank you for purchasing Futaba's SBS-
01RO RPM sensor. This sensor, used
in conjunction with a telemetry enabled
transmitter/receiver, is used to indicate the
number of rotations (propeller, rotor, etc. ) of
the item to which it is attached. The number
of rotations of a model in the sky is a system
which can be checked with a transmitter etc.
To maximize your enjoyment, and to ensure
proper sensing, please read through this
manual thoroughly. We also encourage you to
retain the manual for future reference should
the need arise.
●The SBS-01RO is designed for use
with Futaba telemetry systems .

 WARNING
 To utilize the SBS-01RO sensor, connect it
to the S.BUS2 port of the Futaba telemetry
enabled receivers.
■ The SBS-01RO will not function properly if connected to
an S.BUS port or other channel ports.
 Be careful of the connector polarity.
■ Because of the case construction, reversing the polarity
may cause trouble or sparking from the wiring.
 Mount the sensor in accordance with the
installation method described below.
■ If the SBS-01RO drops out during flight, it cases erratic
operation or loss of control.
 Vibration-proof the PC board and mount the
SBS-01RO where it will not be exposed to
fuel and water.
■ Electronic parts are used at the PC board. Take protective
measures against vibration, shock, high temperature, and
so forth.
 When mounting the SBS-01RO to the
fuselage, be sure there is some slack in the
wiring cable.
■ If the cable is too tight, vibration may cause the wire to break
or the connector to be dislodged and cause a malfunction.
 Always perform an operation check after
assembling.
■ Do not fly until inspection is complete.
 Don't touch a sensor during engine motor
rotation.
■ When a rotation portion is touched, there is a possibility
of carrying out a large injury.
 Do not use the SBS-01RO with anything
other than an R/C model.
 Don't make different connection from a
manual.
■ It will break down, if different connection is made.
Please note that the proper default slot for
this accessory is number 2. Information
on how to change the slot assignment is
included in the transmitter's manual.
The SBS-01RO uses an optical
sensor. To operate properly the
prop or rotor being measured must
be fairly brightly lit. Typically the
sensor will not operate properly
indoors, on cloudy days or in early
mornings/late evenings when the
angle of the light striking the prop
or rotor is bad. When one of these
conditions exist, the RPM will be
displayed as 0.

The distance between the sensor and the
surface of rotation less than 150 mm.
*Mount the sensor as close as possible to the
prop or rotor.
*The color of the prop or rotor could cause the
RPM to not be detected.
*The SBS-01RO only works in sunlight.
● Sensor Mounting Example
[ Airplane ] [ Helicopter ]
The SBS-01RO may only be used
with telemetry enabled receivers
that offer S.BUS 2 port. Please refer
to the manual(s) that accompanied
your transmitter and/or receiver for
proper connection methodology.
T h e S B S -01R O i s n o t o p t i m a l f o r
helicopter use due to the large distance
between the rotor and sensor, as a
result, the reading can be unstable. We
recommend the SBS-01RM magnetic
sensor be utilized for helicopters.
The sensor defaults to two blades. If
the prop/rotor has more than 2 blades
this option must be changed in the
transmitter. (Refer to the transmitters
manual.)
Each sensor has a unique ID number
printed on it. If more than one of the
same type of sensor is utilized in a model,
the ID will need to be input into the
sensor menu of your transmitter.

It attaches to the position which
is rotation within the limits of
a main rotor and with which a
stabilizer does not interfere.
Use strong double-sided tape
or screws to mount to the
fuselage of an airplane.
