Applicable systems: Futaba FASSTest-2.4 GHz system
transmitter
If R7103SB does not use S.BUS/S.BUS2 system, it can
perform only operation of 3 channels. However, if S.BUS/
S.BUS2 system is used, use of the maximum channel of
a transmitter can be performed. You have to use S.BUS/
S.BUS2 servo, in order to use S.BUS/S.BUS2 system.

Thank you for purchasing a Futaba
R7103SB FASSTest-2.4 GHz
compatible receiver. The
R7103SB
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.
R7103SB
has a merit which acquires the information

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

of
R7103SB
can choose an output channel from the
11 modes

FASSTest
FASSTest
is a bidirectional communication system between the R7103SB
receiver and FASSTest capable transmitters. Multiple optional telemetry sensors
may be connected to the
S.BUS2
on the receiver and that data is in turn displayed
on the transmitter.
*Please see your transmitters operation manual to configure transmitter to operate
with telemetry sensors.
Please refer the table below for LED status vs
receiver's condition.

Usage precaution
• Analog servos cannot be used with the R7103SB in the FASSTest 12CH mode.
• The R7103SB receiver can only be used with FASSTest capable transmitters.
WARNING
Changes or modification not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
The R7103SB 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 connect the servo or gyro which do not correspond to S.BUS2 port
S.BUS2.
• When the servo and gyro which do not correspond to S.BUS2 are connected to S.BUS2
port, there is a danger of falling by malfunction.
Turn on the power in transmitter
→
receiver order. In addition, always check
the operation of all the servos before flight.
Do not insert or remove the servo connector while the receiver power is
ON.
•Since the S.BUS servo switches the operation mode automatically according to the
type of signal (S.BUS signal/PWM signal) from the receiver, if the connector is inserted
or removed while the power is ON, an S.BUS connected servo will be erroneously
recognized and may stop.
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 R7103SB 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 30 mm 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.
