Initial setup:
After connecting the battery (red = plus, black = minus) you
hear 3 descending tones. When connecting 4s to 6s Lipo
follows a number of beeps according to the number of cells.
With high cell packs (7 to 12s Lipo) follow 2 high and 2
deeper tones. 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.
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 5.5mm / 6mm PK connectors have proven to be
the best choice. 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.
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/50V should be soldered
between plus and minus wires every 20cm. You might also
consider using our capacitor module YGE Cap´s typ 7.
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
switched on middle, 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 2.9V 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.
Innrunner 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.

The easiest to make these changes is the ProgCard. There is
also the possibility to perform the setup with the transmitter;
however it will not be explained here. You will find it in the
RC-setup manual under www.yge.de in the Download area.
In case you get inadvertently in the programming mode during
a normal start-up (throttle stick at full power), simply
disconnect the battery, lower the stick to stop, and connect
the battery again. Thus you won’t modify the adjustments.
Lipo protection / under-voltage protection:
Because of the tension driven load adjustment it is possible to
fly further with low power, since the battery recovers with
smaller load. However, if the tension continues to break in, the
motor is switched off.
Temperature / overload warning:
If the speed controller’s temperature exceeds its limit,
because of overloading or lack of cooling, after landing and/or
motor stop, a warning signal is issued (3 Beeps in the
interval). But the motor is not switched off in flight unless the
temperature becomes extremely critical, then the motor
switched off.
The partial load operation between half and nearly full power
is the most difficult area for an ESC. In addition the running
time becomes longer and longer with the Lipo technology. If it
should come to repeated temperature warnings, better
cooling should be provided or current should be reduced.
These warnings are to be regarded as overload warnings and
not as normal operating condition. Because at high
temperature the components are strongly stressed, this leads
to a decreased life time.
You achieve a better cooling not only through sufficiently
dimensioned air intake, but even more efficiently through a
larger air outtake, in order to avoid a heat accumulation.
You achieve smaller currents by using a smaller propeller or a
one cell smaller battery.
Opto coupler:
In the case of the use of an external BEC the galvanic
separation of the opto-coupler is bypassed, which can
possibly feed disturbances through to the receiver. Here
we recommend the use of our ferrite core for additional
filtering.
.
Caution:
Fundamentally it is important to make sure that no objects
are within the propeller circle when batteries are
connected. The use of this speed controller is therefore
allowed only in situations where damages and personal
injuries are impossible. A damaged governor (e.g.
broken, damaged by polarity inversion or humidity) must
not be reused under any circumstances. Otherwise it can
come to a later malfunctions or failures.
The ESC may only be powered from batteries, a use from
power supplies is not allowed.
Trouble shooting:
2 Beeps/flashes: Under-voltage identification
3 Beeps/flashes: Temperature rise warning
5 Beeps/flashes: Receiver signals failed
6 Beeps/flashes: start up failed
The ESC signals any error that happened during flight
acoustically (motor) and optically with a blinking LED code.
Errors 2 and 3 are signaled after motor stop, but aren’t stored
as long as the ESC didn’t cut off completely (low voltage /
temperature warning). In case the error led to a complete cut
off, then it is not cleared by a tension RESET. The deletion
can take place only on purpose by connecting the battery with
the stick at full power and/or with 100% throttle pre-selection
(throttle curve), and disconnecting it again after the interval
beep. Please you leave the stick at full power, while
disconnecting, otherwise you activate the RC-Setup.
Likewise the errors can be cleared by activating the
ProgCard.
With an activated brake, the error is only signaled after a
tension reset or in wind milling position.
Warranty:
We give 6 months warranty on this speedcontroller. Any
other requirements are excluded. That applies in
particular to requirements for damage or injuries
compensation due to malfunction or failure. For damages
to property or personal injuries and their consequences,
which developed from our supply or craftsmanship, we do
not take any liability, since we have no control on
handling and use.
