Trouble

Possible Reason

Solution

After power on, motor doesn’t work,
and the cooling fan doesn

’t work

The

connections

between

battery pack and ESC are not
correct

Check the power connections
Replace the connectors

After power on, motor can’t work,
but emits “beep-beep-, beep-beep-”
alert

tone.

(Every

group

of

“beep-beep-” has a time interval of
1 second )

Input voltage is abnormal, too
high or too low

Check the voltage of the battery pack

After power on, red LED always
lights, the motor doesn

’t work

Throttle signal is abnormal

Plug the control wire into the throttle
channel of the receiver correctly.

The motor runs in the opposite
direction when it is accelerated

1)The wire connections between
ESC and the motor are not
correct
2)The chassis is different from
the popular design

1) For sensorless motor: Swap any two
wire connections between the ESC and
the motor. Or use the method #2
2) For sensored motor: Please check
the wire connections, they must be A-A,
B-B, C-C respectively. If the connections
are correct, please change the

“Motor

Rotation

programmable

item

to

“CW(Clockwise)”

The motor suddenly stops running
while in working state

The throttle signal is lost

Check the transmitter and the receiver
Check the signal wire from the throttle
channel of your receiver

The ESC has entered the Low
Voltage Protection Mode or
Over-heat Protection Mode

Red LED flashing means Low voltage
protection. Green LED flashing means
Over-heat protection

When accelerating quickly, the
motor stops or trembles

1) The battery has a bad
discharge performance
2) The gear rate is too small
3) The

“Start Mode (Punch)” of

the ESC is too aggressive

1) Use a better battery
2) Use lower KV motor or change the
gear rate, choose smaller pinion
3) Select a softer option for the

“Start

Mode (Punch)

When the throttle stick is in the
neutral range, the red LED and the
green LED flashes synchronously

The motor is a sensored motor,
but the ESC detects abnormal
signal from the sensor, so it
changes to sensorless mode
automatically

1) Check the connection of Hall sensor
cable to make it firmly connect the motor
with the ESC
2) The Hall sensors in the motor are
damaged, please change the motor
