◆
Thank you for purchasing a Futaba R7018SB FASSTest-2.4GHz compatible receiver. The R7018SB 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. It also includes both standard PWM output ports and S.BUS output ports.
The R7018SB has a Dual Battery System. Multiple servos can be driven by connecting 2 large capacity batteries. Even if the voltage
of one battery drops, the other battery allows safe ight. The R7018SB can also be switched the FASST-Multi-ch System.
●
Applicable systems: Futaba FASSTest-2.4GHz / FASST-Multi-ch system transmitter
Usage precaution
• Analog servos cannot be used with the R7018SB in the
FASSTest 12CH mode.
• When the FASST Multi-ch High-speed Mode is used,
analog servos cannot be used at the CH1〜6 outputs
for convention systems. However, in other than the
FASSTest 12CH mode, analog servos can be used at
CH7〜16, DG1, and DG2 at any time.
• Don't connect to Extra Voltage before turning on a receiver.
WARNING
Changes or modication not expressly approved by the party
responsible for compliance could void the user’ s authority to
operate the equipment.
When the model is not being used, always remove or
disconnect the battery.
■ When the switch is off, a slight amount of current still flows. Unless the
switch and battery are disconnected, the battery will be damaged from
excessive discharge.
The R7018SB 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.
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 R7018SB 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.
Antenna installation for carbon fuselage
You must leave 30mm 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.
Be careful of connector insertion
Don't connect an S.BUS servo / gyro to S.BUS2 connector.
Do not connect the power supply battery to other than the
power supply connector.
■ There is the danger of ignition, explosion, or burning.
Link precaution
Do not perform the linking procedure while the motor's main
wire connected or the engine is operating as it may result in
serious injury.
When the linking is complete, please cycle the receiver power
and ensure the receiver is properly linked to the transmitter.
Please power up your system in this order. Transmitter rst,
followed by the receiver.
If the R7018SB receiver was previously linked to another
transmitter, make sure that transmitter is not operating while
linking the receiver to the new transmitter.

WARNING
Never reverse the battery polarity.
■ A reverse connection the battery terminals may cause
abnormal heating, fire and burns.
Do not short circuit the battery terminals.
■ A short circuit across the battery terminals may cause
abnormal heating, fire and burns.
Be careful when soldering to the plug; don't overheat
the plug with your soldering iron and take great care to
avoid short-circuits on the plug.
■ Such a overheat and short-circuit would destroy the plug.
