cells' constantly high voltage curve; in this case the speed
controller is unable to cut the motor in good time. In these
circumstances you should fly using a current sensor or a timer, to
avoid discharging the drive battery to a dangerous level.

INDING AND CORRECTING FAULTS
- When you connect the battery, the motor does not start, and the
speed controller beeps:
•
Double beeps [••_••_••...] at one-second intervals
=> the battery voltage is too high or too low
•
Single beeps [•___•___•...] at two-second intervals
=> non-standard throttle signal
•
Single beeps [•••••...] at 0.25 second intervals
=> throttle stick is not at Idle position
•
Rising sequence of sounds after two short beeps [•_•]
=> throttle channel is reversed; controller is in programming
mode.
- Motor rotates in the wrong direction:
•
Interchange any two of the three motor wires.
- Nothing works: receiver, servos and speed controller do not
respond in any way
•
Check all plugs, sockets and soldered joints for poor or
intermittent contact, and check polarity (+/-) once more. If
the system still does not work, ask for advice from the
dealer who sold you the speed controller.
- The motor stops when running:
•
Throttle signal not reaching the controller
•
Controller has entered low-voltage cut-off mode
•
One or more connectors not making contact, or only making
intermittent contact.
