TROUBLESHOOTING

Trouble
Motor doesn't work, but
there are audible tones
signalling the number of cells
after powering up ESC.
Motor doesn't work and no
audible tone emitted after
connecting the battery. Ser-
vos are not working either.
Motor runs in reverse
rotation.
Motor stops running in flight. Throttle signal lost.
Motor restarts abnormally
during the flight.
ESC Overheats.
Possible Reason
The ESC throttle calibration has
not set up.
Poor/loose Connection between
battery Pack and ESC.
No power
Poor soldered connections (dry
joints).
Wrong battery cable polarity
ESC throttle cable connected to
receiver in the reverse polarity.
Faulty ESC
Wrong cables polarity between
the ESC and the motor.
Battery Pack voltage has reached
the PCO Low Voltage Protection
threshold.
Possible poor cable connection.
Possible RF Interference at the
flying field.
Inadequate cooling air circulation. Relocate the ESC to allow better ventilation.
Servos drawing too much current
and over loading the ESC.
Over sized motor or prop
Action
Set up the ESC throttle calibration.
Clean connector terminals or replace
connector.
Replace with a freshly charged battery pack.
Re-solder the cable connections.
Check and verify cable polarity.
Check the ESC cable connected to the ESC
to ensure the connectors are in the correct
polarity.
Replace ESC
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 position of the
receiver's aerial and ESC cables to ensure
there is adequate separation to prevent RF
interference. Install a ferrite ring on the ESC
throttle cable.
Land the model immediately and replace the
battery pack.
Check and verify the integrity of the cable
connections.
The normal operation of the ESC may be
susceptible to surrounding RF interference.
Restart the ESC to resume normal operation
on the ground to verify recurrence. If the
problem persists, test the operation of the
ESC at a different flying field.
Use servos that are adequately sized for
the ESC. The maximum BEC current drawn
should be within the BEC limits.
Reduce Prop size or resize the motor.
