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

5 seconds later, the motor will beep two

The motor will beep a long beep to
indicate the calibration is complete.
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%
Perform this calibration when using for the first time or when changing
the set. Let ESC read the operating range of throttle.
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
When using with FASSTest or T-FHSS Air, make one of the following set-
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
• 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.
The ESC will monitor the motor speed (RPM) during the start-up process. When the speed stops
increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time,
if the throttle amount is less than 15%, then the ESC will automatically try to restart up; if it is larger
than 20%, then you need to move the throttle stick back to the bottom position and then restart
up the ESC. (Possible causes of this problem: poor connection/ disconnection between the ESC and
motor wires, propellers are blocked, etc.)
The ESC will gradually reduce the output but won’ t cut it off completely when the ESC temperature
goes above 110° . For ensuring the motor can still get some power and won’ t cause crashes, so
the maximum reduction is about 50% of the full power. The ESC will gradually resume its maximum
power after the temperature lowers down. In addition, the ESC temperature cannot exceed 70°
when it’ s powered on. Otherwise, it cannot be started up but flashes Blue LED and beeps a series of
beeps to indicate the ESC temperature is too high. (Here we are describing the ESC’ s reaction in the
“Soft Cutoff” mode, while if in the “Hard Cutoff” mode; it will immediately cut off the power.)
• 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.
The ESC will cut off the power/output and automatically restart itself when the load suddenly
increases to a very high value. If the load still remains high or the motor still remains out of sync, then
it will completely cut off the power/output.
• Low-voltage Cutoff Protection
When the operating voltage goes below the preset cutoff voltage, the ESC will gradually reduce the
output but won’ t cut it off completely. For ensuring the motor can still get sufficient power to land
the aircraft safely, so the maximum reduction is about 50% of the full power. You need to change
another fully charged battery to resume the operation when the low-voltage cutoff protection is
• Over-current Protection
During use, the ESC will cut off the output immediately if the current exceeds the regulated value
and then resume it quickly; the ESC will cut off the output completely and won’ t resume it if the
regulated value is exceeded again.
