We point out that the mode-setup has to be
successfully done before using the
controller!
For Navy please always choose mode 5.
It is also possible to set the half throttle way.
For LMT inrunners, the following settings are
Necessary:
Initial torque Normal
If you are using a Futaba transmitter, please
Set the framerate to 14ms (analog).
Start-up:
After connecting the main battery you will hear 3 descending
beeps. You need to connect the motor to hear the beeps;
whereby the connected motor acts as a beeper.A number of
beeps will follow according to the number of cells; a long beep
stands for 5 cells and a short beep for one cell.
Example: long...long...short...short - 5 + 5 + 1 + 1 =12 cells. If
the transmitter is now in the correct stop-position, you will hear
4 ascending beeps.
- The controller is now ready- .
If the motor turns in the wrong direction, it can be reversed by
exchanging 2 of the 3 motor wires.
Use only clean and tight gold connectors for the motor and
battery. The 5,5mm or 6mm gold-connectors have proven to
be the best choice. 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 30cm. If longer wires are necessary, more switch
resistant additional capacitors have to be used (Ultra Low
ESR). We recommend our capacitor module YGE Cap's 9.
Longer motor cables can be used. Twist the three cables in
order to minimise interference emission.
Attention:
Inverting battery polarity leads to severe damage and
loss of warranty!
Mode Programming:
1. For safety reasons remove ALL rotor blades!
2. Switch on the transmitter and move the throttle stick to
maximum (100%).
3. Connect the battery to the ESC → wait for the interval
beep: ♪♪♪ ... ♪♪♪ after 20 beeps the setup menu is
entered: confirmation ♪♪ .
4. Move the throttle stick to minimum and choose the
mode:
♪ Vbar - gov Mode 1
♪♪ Gov - mode Mode 2
♪♪♪ Gov - store Mode 3
♪♪♪♪ Glider with folding propeller and brake Mode 4
♪♪♪♪♪ Navy / Motor plane without brake Mode 5
♪♪♪♪♪♪ Motor plane with F3A brake Mode 6
5. At the desired mode, move the throttle stick to maximum:
confirmation ♪♪.
If no mode has been selected, the mode programming
starts again with mode 1 = Vbar - gov, etc....
6. Once a mode has been selected, move the throttle stick
to minimum: confirmation ♪♪.
You will hear the beeps acc to the number of cells and now
the ESC is armed and ready for use.
- THE END -
PC-Software:
In the mode-programming, all parameters are set
automatically to useful values. We recommend to set as
less as possible in the PC-Software. Usually it is enough to
set the telemetry-settings, if necessary. For programming
with the PC-Tool, the optional USB-Adapter is necessary.
Please use the attached 3-pin telemetry-cable (Not the
telemetry cable!) with the blue JR-plug for connecting the
ESC to the USB-adapter. More informations in the manual
of the USB-adapter.

Telemetry RPM-signal (ext. Gov.) GND (- receiver)
GND (- receiver) Voltage from receiver 5,5-8,4V throttle signal
Lipo protection / under-voltage protection:
Because of the voltage-driven load adjustment, it is
possible to fly further with low power, because the battery
recovers with smaller load. However, if the voltage
continues to break in, the motor will be switched off.
Active free-wheel:
The unlimited partial load capability refers to the maximum
full power current of the respective ESC types.
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! Only
when the temperature reaches an extremely critical level,
rpm will be reduced to 70% of the current power.
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 comes to 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. At high
temperatures the components are very stressed and this
leads to a decreased service life.
You achieve better cooling not only through sufficiently
dimensioned air intake, but even more efficiently through a
larger air outtake, in order to avoid heat accumulation.
You achieve smaller currents by using a smaller propeller
or a battery with one less cell.
Caution:
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 controller (e.g. broken, damaged by polarity
inversion or humidity) must not be reused under any
circumstances. Otherwise malfunctions or subsequent
defects may arise at a later date.
The ESC should only be powered by batteries, the use
from power supplies is not allowed.
Analysis of malfunctions:
2 Beeps/flashes: Under-voltage identification
3 Beeps/flashes: Temperature rise warning
4 Beeps/flashes: Overcurrent
5 Beeps/flashes: Receiver signals failed
6 Beeps/flashes: start up failed
The ESC has a yellow LED - status indicator light as well
as a red LED light to analyze error. A flashing sequence
indicates errors during operational use. After about a 1
minute successful run the error will be automatically
deleted.
Connections:
Telemetry:
If you use a backup-battery, please make sure, that you
power up the ESC first, before connecting the backup-
battery to the receiver. Otherwise the telemetry might not
work. The ESC sends all ESC-related data via telemetry,
such as voltage, current, capacity, BEC-voltage, RPM,
throttle percentage, PWM, BEC-temperature, warnings and
error messages. It depends on the used receiver and
transmitter, which of these data will be shown in the
transmitter.
YGE (preprogrammed):
The YGE-protocol is for example for use with YGE TexY
(Futaba, Spektrum, FrSky, Core), MSH Brain 2 or Spirit
FBL.
Warranty:
Our warranty conditions are based on the European
Statuary Warranty. 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.
