CONTENTS
ESC ( motor controller) that supplies power
from the drive battery (BEC- Battery Eliminator
Circuit) to the receiver cannot be used.
Ordinary switches
(SSW-J, HSW-J, HSW-L,
etc.) cannot be used.
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 Telemetry Port before turning
on a receiver.
WARNING
Changes or modication not especially 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.
When only one battery is connected, always insulate the
unused connector.
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
power 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.

Dual Battery System
Two power supply batteries can be connected to the R7018SB. Power is supplied from
the battery with the highest voltage. The operating time is the total time of the 2 batteries．
For example, even if the voltage of one battery drops, power can be supplied from the
other battery. Even one battery can be used, but safer ight is possible if 2 batteries are
used.
This receiver employs an electronic switching (current is controlled by an FET circuit) system. When the exclusive switch is
set to ON or is pulled, the power is turned on. Switches other than the exclusive switch cannot be used. In addition, since a
very small current ows even when the power is off, always disconnect the battery from the connector when the receiver is not
in use.
One or 2 batteries can be connected. When 2 batteries are connected, the battery with the highest voltage is used. When only
one battery is connected, always insulate the unused connector. The battery can be connected to either side.
In addition, since this receiver does not have a built-in voltage regulator, use batteries with sufficient capacity for the
specications and number of servo motors to be used.

Even if the power supply

When the switch is set to ON,
power is supplied from the battery
with the highest voltage. The
operating time is the total time of
the 2 batteries.
Electric power will be automatically
and alternatively supplied from the
battery which voltage is higher.

FASSTest
FASSTest
FASSTest is a bidirectional communication system between the R7018SB 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.
Link to the transmitter : FASSTest
1 Bring the transmitter and the receiver close to each
other, within 20 inches (half meter).
2 Turn on the transmitter. Place the transmitter into the
receiver linking mode.
3 Turn on the receiver.
4 The receiver will wait for the linking process to begin
for 2 seconds. Following that it will return to the normal
operation mode.
5 When the LED of the receiver changes from blinking red
to solid green, linking is complete.
(A link waiting state is ended in 1 second.)
• Refer to the transmitters operation manual for complete
details on how to place the transmitter into the linking
mode.
• If there are many FASSTest systems turned on in close
proximity, your receiver might have difficulty establishing
a link to your transmitter. This is a rare occurrence.
However, should another FASSTest transmitter/receiver
be linking at the same time, your receiver could link to
the wrong transmitter. This is very dangerous if you do
not notice this situation. In order to avoid the problem,we
strongly recommend you to double check whether your
receiver is really under control by your transmitter.
• If the System Type of the transmitter is changed, the
receiver will need to be re-linked to the transmitter.
S.BUS2
S.BUS2 extends S.BUS and supports bidirectional
communication. Sensors are connected to the S.BUS2
port.
*Only S.Bus2 capable devices may be connected to the S.Bus2
port. Standard S.Bus servos and gyros should not be connected
to the S.Bus2 port.
Receiver voltage transmitter display
The voltage displayed at the transmitter is only that of the
battery currently in use (battery with the highest voltage).
*The voltage of the 2 batteries cannot be displayed individually.
Extra Voltage Telem etry port
It connects with the battery for power, etc.
External voltage input cable (CA-RVIN-700) of an option
is used. The voltage of the battery can be displayed with a
transmitter.

methods and other details.
When using Multi prop (MPDX-1)
The MPDX-1 can be used with FASSTest by merely
setting the corresponding transmitter. (Refer to the
instruction manual of the corresponding transmitter.)
When using the MPDX-1 Multi Prop Decoder (sold
separately) with the FASST system, change the setting by
the following method.
Enable the MPDX-1 at channels 11 and 12. (Initial value:
OFF)
Channels 11 and 12 cannot be used individually for
MPDX-1 output.
The MPDX-1 extends 1 channel to 8 channels. However,
since the response speed becomes slower and there are
functional restrictions, use it at simple switch operation
and other applications that require numerous channels.
Multi prop mode Change method
1. Switch the receiver to the FASST system (Normal or
High-speed).
2. Turn on the receiver power. (Transmitter power off)
3. Press the Link/Mode switch for at least 10 seconds.
4. When the LED blinks red and changes to red/green
simultaneous rapid blinking, release the switch.
5. The receiver enters the multi prop mode and the LED of
the current mode blinks. (Initial value: OFF)
6. Each time the switch is pressed, the mode changes.
7. When the receiver was switched to the desired mode,
press the Link/Mode switch for at least 2 seconds.
8. When the LED switches to red/green simultaneous
rapid blinking, mode switching is complete. Release the
switch.
9. When switching is complete, turn on the power. When
the power is turned on, the receiver switches to the new
mode.
FASST
When switched, the R7018SB can use the FASST-Multi-ch mode. When the FASST system is used, the telemetry and
Extra Voltage ports cannot be used. The FASST system has a Normal mode and a High-speed mode. However, in the
High-speed mode, analog servos cannot be used at CH1 〜6.
