R6303SB
Thank you for purchasing a Futaba R6303SB FASST-2.4GHz receiver.
The R6303SB has an S.BUS system output port and 3 conventional
system channel outputs. It can also be used with conventional system
servos, etc. in addition to S.BUS system compatible servos and gyros,
etc. When the linking procedure is performed, R6303SB recognizes the
signal mode (FASST-2.4GHz 7ch mode or 8ch/10ch/Multi-ch mode)
automatically.
The R6303SB can change the output CH from seven groups (CH group
table).
In addition, the operating mode (high-speed mode/normal mode) can be
selected.
Applicable systems: FASST-2.4GHz 7ch or 8ch/10ch/Multi-ch system
Antenna installation precaution
 WARNING
Be sure that the two antennas are placed at 90 degrees to

each other.
• Futaba's dual antenna diversity, or DAD, then seamlessly selects the
best signal reception between these antennas to ensure that there is
no loss of signal.
Antenna installation for carbon fuse
 WARNING
The last 30mm of the antenna tip must be fully exposed.

• Please make sure that the exposed portion will not be able to
slide back inside the aircraft by any forces during flight.

R6303SB Specifications
FASST-2.4GHz (7ch/8ch/10ch/Multi-ch) system/S.BUS port and 3 channels for
conventional system/high-speed receiver
• Dual antenna diversity
• Size: 0.89 x 1.47 x 0.37 in. (22.5 x 37.4 x 9.3 mm)
• Weight: 0.25 oz. (7.2g)
• Power requirement: 3.7V to 7.4V(Voltage range: 3.5 to 8.4V)
* Be sure that when using ESC's regulated output the capacity of the ESC must meet your usage
condition.
* The Battery F/S voltage is set for 4-cell NiCd/NiMH battery. Battery F/S function doesn't
work properly when other type battery is used.
* The fail safe function can be set for each channel when on "Multi-ch" mode, however, it differs
according to the transmitter. When on "7ch" mode, the fail safe function can be set for 3-channel
only.
* S.BUS port: R6303SB can be used up to 7 channels or less on the "7ch" mode and 16 channels +
DG1/2 or less on the "8ch/10ch/Multi-ch" mode, however, it differs according to the transmitter.

Usage condition for conventional system output
(Ch1-3) on "High Speed mode"
 CAUTION
The "High Speed mode" accept the digital servos only or

most type of peripherals.
• If an analog servo is connected to these outputs it will cause a
malfunction. Please check the peripherals if there is a malfunction full
stick movement. If there is a malfunction change the receiver back to
"Normal mode."
Power Source Precautions
It is not recommended to use a power source of less then 4.0V.
However if less than 4.0V is used please keep in mind the conditions
below..
• The Fail Safe Function MUST be set to "OFF" since it will disturb the
normal operation of the receiver.
• Please make sure that the fully loaded condition on the ESC and the
Servos will not disturb normal receiver operation before the start of
your flight.
This is VERY Important once the voltage drops below 3.5 volts the
receiver will no longer continue to operate.
• Please be sure that everything on continues to work correctly all the
way down to 3.5 volts. ie: Servos, ESC...
The input voltage must not exceed the servo rating or 8.4V which ever
is lower.
(Connectors)
