Begin To Use Your New ESC
IMPORTANT! Because different transmitter has different throttle range, please calibrate throttle range
before flying.
Throttle range setting (Throttle range should be reset whenever a new transmitter is being used)
1.Switch on the transmi t ter, move throttle stick to the top position.
2.Connect battery pack to the ESC, and wait for about 2 seconds.
3.The "Beep-Beep-" tone should be emitted, means the top point of throttle range has been confirmed.
4.Move throttle stick to the bottom position, several "beep-" tones should be emitted to present the amount of
battery cells.
5.A long "Beep-" tone should be emitted, means the lowest point of throttle range has been correctly confirmed.
Normal startup procedure
1.Move throttle stick to bottom position and then switch on transmitter.
2Connect battery pack to ESC, special tone like "♪ 123" means power supply is OK.
3.Several "beep-" tones should be emitted to present the amount of lithium battery cells.
4.When self-test is finished, a long"beep-----" tone should be emitted.
5.Move throttle stick upwards to go flying.
Protection Function
1. Start up failure protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off
the output power. In this case, the throttle stick MUST be moved to the bottom again to restart the motor. (Such a
situation happens in the following cases: The connection between ESC and motor is not reliable, the propeller or
the motor is blocked, the gearbox is damaged, etc.)
2. Over-heat protection: When the temperature of the ESC is over about 110 Celsius degrees, the ESC will reduce
the output power.
3.Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further
loss for 2 seconds will cause the output to be cut-off completely.
Trouble Shooting
Trouble
After power on, motor does not work,
no sound is emitted
After power on, motor does 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)
After power on, motor does not work,
such an alert tone is emitted:
"beep-, beep-, beep- "(Every "beep-" has
a time interval of about 2 seconds)
After power on, motor does not work,
such an alert tone is emitted:
"beep-, beep-, beep-" (Every "beep-" has
a time interval of about 0.25 second)
After power on, motor does not work, a
special tone " ♪56712" is emitted after 2
beep tone (beep-beep-)
The motor runs in the opposite direction
Possible Reason
After power on, motor does not
work,no sound is emitted
Input voltage is abnormal, too high
or too low
Throttle signal is irregular
The throttle stick is not in the
bottom (lowest) position
Direction of the throttle channel is
reversed, so the ESC has entered
the program mode
The connection between ESC and
the motor need to be changed
14
Action
Check the power connection.
Replace the connector.
Check the voltage of battery pack
Check the receiver and transmitter
Check the cable of throttle channel
Move the throttle stick to bottom
position
Set the direction of throttle
channel correctly
Swap any two wire connections
between ESC and motor
