pause
(* * * *) is emitted.
Motor doesn’t work after powering up

ous beeping tones
(****) is emitted.

Motor runs in reverse rotation Motor
stops running in flight.
Motor stop running.
Motor restarts abnormally ESC
Overheats
Check and verify that the ESC cable
is connected to the Throttle channel
on the receiver.
Check the transmitter and receiver to
verify that there is throttle signal
output.
(Connect a spare servo to verify
throttle channel operation)
Move the throttle stick to the
minimum position.
Enter the servo reverse menu on
your transmitter and reverse the
throttle channel.
Note: For Futaba radios set the
throttle channel to Reverse.
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 cables
to ensure there is adequate separa-
tion to prevent RF interference.
Install a ferrite ring on the ESC’s
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.
Relocate the ESC to allow better
ventilation
Use servos that are adequately
sized for the ESC. The maximum
BEC current drawn should be within
the BEC limits.
Prop down or resize the motor
The ESC is unable to detect the
normal throttle signal from the receiver
The throttle stick is not in the minimum
position at power up.
Reversed throttle channel caused the
ESC to enter the programming mode.
Wrong cables polarity between the
ESC and the motor.
Lost throttle signal
Battery Pack voltage has reached the
Low Voltage Protection threshold.
Possible bad cable connection
Possible RF
Interference at the
flying field.
Inadequate
Ventilation
Servos drawing too much current and
over loading the ESC.
Over sized motor or prop
