Initial setup:
After connecting the battery (red = plus, black = minus)
you hear 3 descending tones. Subsequently, follows a
number of beeps according to the cell number of the
connected Lipo battery. In case the transmitter stick is in
throttle off, you hear now 3 ascending tones.
You need to connect the motor to hear the beeps, as it is
the motor itself which acts as a speaker.
--- The ESC is ready for use. ---
If the motor turns in the wrong direction, exchange simply
2 of the 3 motor wires.
Use only clean and tight gold connectors for motor and
battery. The 3.5 mm PK connectors have proven to be
the best choice from 30 to 80A. Pay attention for the
battery connector to choose a polarity safe system.
Exchange low-friction or oxidized plugs and sockets.
Because only tight sitting contacts will ensure a high
current flow, protect the speed controller against
dangerous voltage peaks and avoid disturbances. With
the 120A and 160FAI types please use you 5.5 and/or
6mm PK gold connectors, because the 3.5 and 4mm
connectors are only certified up to 80A. Here the motor
wires are usually shortened to the minimum and soldered
directly to the motor. On the other side, with all ESC
types, the entire wire length, from the controller to the
battery, may not exceed 20cm. If longer wires are
necessary, a Low ESR switching capacitor of 330µF/25V
should be soldered between plus and minus wires every
20cm. You might also consider using our capacitor
module YGE Cap´s typ 5. Likewise the motor wires can
be extended. Then please twist the 3 lines, in order to
minimize interference emission.
Note: Inverting the Battery polarity leads to heavy
damage and to the loss of warranty!!!
General Settings:
The speed controller has a fixed throttle curve setting, so
that with all usual transmitters the stop and full power points
are linearly connected. With all programmable transmitters,
the throttle range should be set to default (±100%), the
center point set to zero and throttle trim enabled.
Nevertheless, with some transmitter types the range needs
to be adjusted. For that the throttle endpoints have to be set
so that one notch before lowest stick position the motor is
stopped and that one notch before full power the motor is
actually at full power. Full power is indicated by the LED that
is completely turned off.
On delivery the Timing is adjusted to 18°, brake is set to mid
level, and the under voltage recognition adjusted to Lipo
mode 3.1 V.
If during spin up rpm variations (wowing or erratic sound) are
experienced, the timing must be increased. If no
improvement can be obtained at 30°, then the motor is
overloaded. Here a smaller propeller, a one cell smaller
battery or a stronger motor will help. If after motor stop you
hear 2 beeps repeating, it means that the battery voltage
dropped down below the setting value. Eventually try a cutoff
voltage of 2.9 or 3.0V per cell. If there is still no
improvement, then the battery is discharged or too weak, the
wires are too long or to small or a connector is out of order.
With an active brake you can hear these warning tones only
in windmill position. This is the small range on the throttle
stick between brake and motor start. You can reach this
position with 2 notches or with a high trim and a short gas
start.
If no automatic timing is wished, it can be adjusted according
to the following guideline.
Inrunner 0 to 12°
Outrunner 18 to 30°
If your motor manufacturer indicates a timing
recommendation, it is of course preferable to use it.
Basic rule: the higher the timing the higher the full power
rpm.
