Trouble Possible Reason Action
After power on, motor will not work, no
sound is emitted
The connection between battery
pack and ESC is not OK
Check the power connection.
Replace the connector.
After power on, motor will not work, such
an alert tone is emitted:
“beep-beep, beep-beep, beep-beep”
(Every “beep-beep” has a time interval of
about 1 second)
Input voltage is wrong, too high or
too low
Check the voltage of battery pack
After power on, motor will not work, such
an alert tone is emitted:
“beep, beep, beep ”(Every “beep” has a
time interval of about 2 seconds)
Throttle signal is irregular Check the receiver and transmitter
Check the throttle channel cable
After power on, motor will not work, such
an alert tone is emitted:
“beep, beep, beep” (Every “beep” has a
time interval of about 0.25 second)
Throttle stick is not in
bottom( lowest) position
Move the throttle stick to bottom
After power on, motor will not work, a
special tone “ ” is emitted after 2
beep tones (beep-beep)
Direction of the throttle channel is
reversed, so the ESC has entered
the programming mode
Set the direction of the throttle channel correctly
The motor runs in the opposite direction The connection between ESC and
the motor needs to be changed.
Swap any two wire connections between ESC and
motor
Throttle signal is lost Check the receiver and transmitter
Check the throttle channel cable
ESC has entered Low Voltage
Protection mode
Land RC model as soon as possible, and then
recharge the battery pack or replace with new pack
The motor stops running while in working
state
Some Connections are not reliable Check all the connections: battery pack connection,
throttle signal cable, motor connections, etc.
Random stop and restart or irregular
working state
There is a strong electro -
magnetic interference in flying
area.
The normal function of the ESC may be disturbed
by strong Electro - Magnetic interference. If so,
simply reset the ESC to resume normal operation
by following the instruction manual. If the function
could not resume, you might need to move to
another area to fly.
Protection Function
1. Start up protection: If the motor failed to start up in 2 seconds while the throttle stick is being moved up, the ESC will cut off the
output power. In this case, the throttle stick MUST be moved to bottom again to restart the motor. (Such a situation happens in the
following cases: The connection between ESC and motor is not reliable, Propeller is blocked, Gearbox is damaged, etc.)
2. Over-heat protection: When the temperature of the ESC is over 110
0
C (230
0
F), the ESC will reduce the output power.
3. Throttle signal lost protection: The ESC will gradually reduce the output power if throttle signal is lost for 1 second; further loss for 2
seconds will cause its output to be cut off completely.
4. “VERY IMPORTANT!” Because different transmitters have different throttle ranges, we strongly suggest you use the “Throttle
Range Setting Function” to calibrate the throttle range. Please read the instruction on page 3 - “Throttle Range Setting”.
