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
specications and number of servo motors to be used.

Even if the voltage of
one of the batteries
drops, power is supplied
from the other battery.
Even if the power supply
wiring of one of the batteries
breaks, power is supplied
from the other battery.
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 Tel e m e t r y p o r t
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.
