Initial setup:
After connecting the battery (red = positiv, black = neg.)
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. 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
disturbances. Take 5.5 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. With all
ESC types, the entire wire length, from the controller to
the battery, may not exceed 25cm. If longer wires are
necessary, a Low ESR switching capacitor of 330µF/25V
should be soldered between pos. and neg. wires every
20cm. You might also consider using our capacitor
module YGE Cap´s typ 5.
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
If no automatic timing is wished, it can be adjusted according
to the following guideline.
Note: Inverting the Battery polarity leads to heavy
damage and to the loss of warranty!!!
General Settings:
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
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.
Please notice that the complete features set can only be
reached through the YGE programming card.
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
0 to 12°
18 to 30°
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.
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.
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.
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.
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.
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
Please look at the label holding the 3 yellow cables to the
right-hand side. There you will find 3 possible BEC
currents, which can be set-up with the Jumper and 4-pole
male multi-point connector.
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.
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!

Basically 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 material and personal damage can be
excluded. A damaged governor (e.g. broken, damaged by
polarity inversion or humidity) should not be reused under
any circumstances. Otherwise, malfunctions or failures might
occur subsequently.
The ESC should only be powered by batteries, the use of
power supplies is not allowed.
Trouble shooting:
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
Likewise the errors can be cleared by activating the
With an activated brake, the error is only signaled after a
tension reset or in wind milling position.
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.
