ESC/Transmitter Calibration
Precautions about Battery F/S
Turn on the transmitter and move the
throttle stick to the high position.
Turn on the transmitter, move the Throttle stick to
the low position, and turn on the throttle cut switch.
If you are in governor mode on a helicopter or use the brakes on an
airplane, set the throttle cut switch on the transmitter. Be sure to connect
the drive battery in the throttle cut state. Release the throttle cut at the
start. After landing, stop the motor with a throttle cut and then remove the
battery.
Connect a battery to the ESC, the motor
will sound " ♪ 1-2-3" to indicate the ESC is
powered on normally.

Before calibration, set the throttle curve of the transmitter to a straight
line of -100% to 100%, and set all throttle-related mixing to INH. Make
sure that the throttle amount corresponding to the maximum throttle
endpoint and the minimum throttle endpoint of the transmitter is 100%
and 0%, respectively.
Start-up procedure
Alarm
1.Power-on Abnormal Voltage Protection：
The ESC will measure the input voltage when it’ s connected to a battery or power
supply. If the input voltage is not within the regulated range, it will take the voltage as
an abnormal voltage and then activate the protection, flash Red LED and beep a series
of beeps.
2.Throttle Signal Loss Protection：
When the ESC detects loss of signal for over 0.25 second, it will cut off the output
immediately to avoid an even greater loss which may be caused by the continuous
high-speed rotation of propeller. The ESC will resume the corresponding output after
normal signals are received.
3.Throttle stick is not at the bottom position：
The motor will beep “B-B-B-B-B-” when the throttle stick is not moved to the bottom
position.
4.Throttle range is too narrow：
The motor will beep “B-B-B-B-B-” when the throttle range you set is too narrow (when
designing this ESC, it requires that the entire throttle range you set cannot be less
than 50% of the whole throttle range available on the transmitter.) The warning tone
indicates the throttle range you set is void and you need to set it again.

Trouble
Possible causes
LED
Throttle Signal Loss
The ESC detects loss of signal for over 0.25 second.
Red LED flashes
Input voltage is abnormal
The input voltage is not within the regulated range.
Red LED flashes
Thermal protection is activated
The internal temperature of the ESC goes above the
regulated temperature range.
Blue LED flashes a short
Low-voltage cutoff protection
is activated
The operating voltage goes below the preset cutoff
voltage.
Blue LED flashes a short
Over-current Protection
The operating current goes above the regulated value. Red LED turns on solid
LED display in case of trouble
During normal operation, the
blue LED on the ESC will light
up when startup is complete.
The red LED lights up at throttle
high and turns off at the throttle
low.
SBM-2
Connect to display telemetry data
on the transmitter.
Emergency battery
Normally, the Receiver power is supplied from the
ESC, and if the drive battery drops, it becomes an
emergency power supply. Set the BEC voltage (only
the servo works) slightly higher than this battery
voltage. When the drive battery is connected, the
emergency battery is charged.
(Example: 6.6 V LiFe battery BEC voltage 6.9 V)
Reverse the throttle channel (CH3) of the
Futaba transmitter.

Mount the receiver and
receiver antenna away from
the MC-9130H/A, motor cord,
power cord, drive battery and
other parts through which a large
current flows.
If the receiver is erroneously
operated by noise, control will be

where it will not be exposed
to oil, grease, and water.
Mount the MC-9130H/A to
the fuselage where there is
an ample flow of cooling air.
Do not wrap the MC-9130H/A
body in aluminum foil.
Such wrapping will cause a loss
of cooling effect and the specified
performances will not be obtained.
Install the motor securely.
Also clamp all the cables.
CAUTION
Do not disassemble the
ESC. Do not open the case
of the product.
Opening the case will damage
the interior. In addition, repair will
become impossible.
Mounting precautions
WARNING
Always use the MC-9130H/
A w i t h i n t h e o p e r a t i n g
conditions range given in the
specifications.
Be sure that the battery
polarity is correct.
Reverse connection will cause
sparking and immediate destruction
or burning inside the ESC.
Never short circuit even
places where there is no
batter y, motor, receiver, or
connector.
Short circuits will cause sparking
and immediate destruction or
burning inside the ESC.
Mount the ESC so that the soldered
part of the cord does not touch
conductive parts.
Operating precautions
WARNING
Be careful that no part of
your body touches parts
that rotate during operation.
Unexpected rotation may cause
serious injury.
Depending on the receiver, the
motor may rotate the instant the
power is turned on.
Do not fly in rainy weather.
If water drops enter the ESC,
control will be lost due to erroneous
o p e r a t i o n a n d i s e x t r e m e l y

an accident. If the ESC operates
erroneously due to the entry of

When not set properly and when
a different model is selected,
control will be lost and is extremely
dangerous.
CAUTION
Do not touch the motor and
ESC immediately after flight.
It will cause a burn.
The BEC voltage (voltage supplied to the receiver) of this ESC is output
at about 5.0 V for a few seconds at startup, and then the BEC voltage set
by the user is output. Therefore, if the battery fail-safe voltage of the
FASSTest and T-FHSS Air receiver is set to 5.0 V or higher, the Battery F/S
function works even though the battery is sufficient.
* The battery fail-safe voltage of FASST and S-FHSS receivers is fixed at 3.8 V, so
there is no problem.
When using with FASSTest or T-FHSS Air, make one of the following set-
tings.
1. Reduce the battery fail-safe voltage to 4.8 V or less.
2. Turn off the battery fail-safe setting.
* As a method of monitoring the battery voltage, check the voltage of the receiver
with a telemetry alarm.
The attached split cable is not
normally used. Used when there is
an update of SBM-2.
