ESC/Transmitter Calibration
Perform this calibration when using for the first time or when changing
transmitter. Let the ESC read the operating range of throttle.
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.
Turn on the transmitter and move the
throttle stick to the high position.
Connect a battery to the ESC, the motor
will sound " ♪ 1-2-3" to indicate the ESC is
powered on normally.
5 seconds later, the motor will beep two
short beeps to indicate the maximum
throttle end point is accepted.
Move the throttle stick to the bottom position
within 3 seconds after you hear those two beeps,
the minimum throttle position will be accepted
1 second later.
The motor will beep "Number" beeps to
indicate the number of Lipo cells you have
plugged in.
The motor will beep a long beep to
indicate the calibration is complete.
Receiver
Precautions about Battery F/S
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.
Flight Mode
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.

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.
