When activating one of the modes, all relevant heli
parameters are set to default. The default will fit almost all
setups. You don’t need to program anything else.
Here is a list of the default settings. (mode 2)
- Timing = 18°
- Brake off
- cut off type / accutype = slow down / Lipo
- cells = none = automatically cell count
- Act. Freew. on / Gov on
- P-Gain = 0,9
- I-Gain = 0,05
- Startup Speed = Heli middle
- PWM-Frequency = 9 kHz
- Startup Power = Auto 1-32
If it is necessary to change the settings, you need the YGE
programming card
In case another mode is selected, all settings are back on
default.
Autorotation (AR) and bailout:
To use the bailout, the motor should not be switched off
during autorotation! Or the ESC uses normal soft start if
switched back to flight mode. The motor needs some rpm for
the bailout, therefore set the rpm very low: the helicopter
should not be able to lift off. We recommend 10 ... 20%
throttle opening. If set too low, the motor or ESC might
overload.
Always makes the bailout at a safe height!
As soon as the model is on the ground, the motor has to be
switched off completely, otherwise there is no soft-start and
bailout is active!
Lipo protection / under-voltage protection:
Because of the tension driven load adjustment, it is possible
to fly further with low power, since the battery will recover with
a smaller load. However, if the tension continues to break in,
the motor will switch off.
Active free-wheel:
The unlimited partial load capability refers to the maximum full
power current.
Temperature / overload warning:
If the Esc, while being operated, gets too hot, the motor will be
reduced to 75% of the current throttle opening. After landing a
warning signal will be issued. (3 single beeps).
The partial load operation between half and nearly full power
is the most difficult area for an ESC. In case of repeated
temperature warnings, better cooling should be provided or
the 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.
A high temperature the components are strongly stressed; this
leads to a decreased life time.
In order to avoid heat built-up, you will achieve better cooling
not just through sufficiently dimensioned air intake, but even
more efficiently through a larger air escape.
You achieve smaller currents by using a smaller propeller or a
one cell smaller battery.
If the speed controller’s temperature exceeds its limit, 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 will switch off!

BEC:
Please look at the label holding the 3 yellow cables to the right-
hand side. There you will find 3 possible BEC voltages, which
can be set-up with the Jumper and 4-pole male multi-point
connector.
YGE 90 LV and 120 LV
On delivery, the Jumper is on level 5,7V. (Now the top two male
connectors are linked). If you connect the two male connectors
in the middle, the BEC is on 7,4V. If you connect the two lower
male connectors, the BEC will be on 8V.
YGE 120 LVK
On delivery, the Jumper is on level 5,7V. (Now the two lower
male connectors are linked). If you connect the two male
connectors in the middle, the BEC is on 7,4V.If you connect the
top two male connectors, the BEC will be on 8V.
YGE 90 LV, 120 LV and 120 LVK
In case you do not connect any of the male connectors or you
loose the Jumper for whatever reason, 5,7V will be set
automatically due to safety reasons. Even 8V servos will work
smoothly.
If you use a receiver battery, the jumper must needs to be set on
the right level. For reasons of safety fix the jumper with glue or
tape before using the controller.
You can use different batteries for backup!
Step 5,7V 4-cell NiMH
Step 7,4V 2-cell Li-Io
Step 8,0V 2-cell Li-Po
The receiver battery can be connected through a switch cable
into a free plug of the receiver or through a y-cable.
Make sure no discharged backup battery is used, because this
would load the BEC additionally by charging the battery. A fully
loaded battery will not be charged.
In case you want to use a Backup-Guard, follow the manual of
the manufacturer.
You can also use the ESC without the BEC. Here you have to
separate the thin plus- wire of the Master cable or use an YGE
opto-coupler. The Slave-cable will not be used.
Caution:
As a rule it is important to make sure that no objects are within
the propeller circle when batteries are connected. The speed
controller can therefore only be used when damage and
personal injuries cannot be sustained. A damaged governor
(e.g. broken, damaged by polarity inversion or humidity) must
never be used again. Otherwise malfunctions or failure might
occur The ESC may only be powered by batteries, it is not
allowed to use power supplies.
Trouble shooting:
The ESC signals any error that happened during flight
acoustically (motor) and optically with a blinking LED code.
2 Beeps/flashes: Under-voltage identification
3 Beeps/flashes: Power-part temperature rise warning
5 Beeps/flashes: Receiver signals failed
6 Beeps/flashes: start up failed
7 Beeps/flashes: BEC temperature rise warning
Warranty:
There is 6 months warranty on the speedcontroller. Any other
requirements are excluded. In particular, this applies to the
requirements for damage or injuries compensation due to
malfunction or failure. For damage to property or personal
injuries and their consequences, which are based on our supply
or craftsmanship, we do not take any liability, since we have no
control over handling and/ or use.
