Protection function
1. Start-up protection: If the motor fails to start normally within 2 seconds after pushing the throttle to start, the ESC will
cut off the output power, and you need to make the throttle calibration again, then ESC can be restarted. Possible reasons:
disconnection or poor connection between ESC and motor, the propeller or motor is blocked by other objects, the gearbox
is damaged, etc.)
2. Over-heat protection: When the temperature of the ESC is over about 110°C, the ESC will automatically reduce the out-
put power for protection, but will not fully shut down the power, reduce it to 70% of the full power at most to ensure the
motor has enough power to avoid crashes.
3. Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, will cut off
output to the motor if the throttle signal is lost over 2 seconds. If the throttle signal recovers during power down, the ESC
will immediately resume throttle control. In this way, the ESC will not protect when the signal loss less than 2 seconds, only
when the signal lost is over 2 seconds or longer time. And the ESC will reduce the output power gradually instead of cutting
off it immediately, so the player has certain amount of time to save the plane, taking into account safety and practicality.
4. Over load protection: The ESC will cut off power or restart automatically when the load increased a lot suddenly, possible
reason is the motor blocked.
Trouble shooting
Trouble
After powering up, ESC
emits the sound of battery
cells, but motor can't run.
After powering up, motor
doesn't run and doesn't
emit any sound.
Motor does n't work and
no audible tone emitted
after connecting the
battery. Servos are not
working either.
Motor does not work but
servos do
When the ESC is powered
on, the motor does not
work and an alarm sound
(continuously beeping)
will sound.
Motor runs in reverse
rotation
Motor stops running in
flight.
Possible Reason
ESC doesn't set throttle range.
1.Bad connection between ESC and battery.
2.Bad soldering cause bad contact.
3.Low voltage of the battery.
1. Poor/loose Connection between battery
Pack and ESC.
2. No power
3. Poor soldered connections
4. Wrong battery cable polarity
5. ESC throttle cable connected to receiver
in the reverse polarity
1. Poor / loose connection between ESC and motor
2. Burnt motor coils
3. The battery pack voltage exceeds the acceptable range.
4. Throttle stick is not at the lowest position
5. The ESC throttle calibration has not set up
The throttle stick is not in the bottom
position after power on.
Wrong cables polarity between the ESC
and the motor.
Lost throttle signal
Action
Set throttle range again.
1.Clean the connectors or replace them, check
the connection polarity.
2.Solder the wires again.
3.Check battery pack, use full-charged battery.
4.Change ESC.
Check all the connections make sure you are doing
it right.
1. Check all the connections make sure you are
doing it right.
2. Change a new motor.
3. Solder the wires again.
4. Check the battery pack, use full-charged battery.
5. Set throttle range again.
Move the throttle stick to the bottom position.
Swap any two of the three cable connections
between the ESC and the Motor or access the Motor
Rotation function via the ESC programming mode and
change the pre-set parameters.
Check proper operation of the radio equipment.
Check the placement of the ESC and the Receiver and
check the route of the receiver's aerial and ESC
