[preparation] Solder suitable connectors to lead wires (red, black) of the ESC. Use a piece of shrink tube for insulation at each connecting
point. Solder suitable female connectors to the three lead wires of the ESC, which are to be connected to three male connectors of the
brushless motor. Use shrink tubes for insulation at connecting points.

Solder suitable female connectors to the
three lead wires. Use a piece of shrink tube
for insulation to each connecting point.
Start protection: the device stops the motor when it is started unintentionally.
the device stops the motor when it loses control, or before
incoming voltage.
Low voltage cut-off:
the device cut off the ESC when no signal from the transmitter is
detected.
No signal cut-off:
the device regulate the output to protect FETs when
temperature of ESC rapidly rises due to overload.
Protection against overheating:
the device reduces sparks when the ESC is connected to a battery.
Anti-spark:
the device detects number of battery cells
automatically.
Automatic detection of battery cells:
In order to maintain an optimum current and rated current of the ESC, cooling air;
propeller slip stream and natural air of atmospheric temperature 20℃ or lower at
wind speed (5m/s or more) over the entire heat sink is required.
The maximum performance limit of ESC greatly changes depending on environmen
-
tal factors such as atmospheric temperature and humidity.
Battery voltage is detecting system. A buzzer tells you how many cells in a battery.
The active free-wheeling reduces heat of the ESC generated during operation, which
is a waste.
Settings of the ESC using an
ESC programmer of OCP-3
Settings of the ESC using an
ESC programmer of OCP-3
With OCP-3 (optional), you can set the ESC more quickly and
easily.
Connect OCA-3100HV/OCA-3070HV to the ESC socket of
OCP-3, and a battery (4.8
〜
7.4V) to the BATT socket of
OCP-3.
Select a setting item by pressing the UP or the DOWN
button.
The LEFT and the RIGHT buttons are to select each item in
the setting or to change the setting.
The following items can be set with OCP-3.

Select a setting item by pressing the UP and the DOWN buttons.
Select or change the setting item by pressing the LEFT and the
RIGHT buttons.
Any chosen value of setting is memorized in the ESC automati-
cally one by one without requesting you any further action to
memorize the value in the ESC.
Select the battery type and number of cells with the LEFT and
the RIGHT buttons.
Setting a number of the battery cells: AUTO
In case NiCd is selected, pass the setting item .
The cut-off voltage is automatically fixed at 50% of an initial value.
Set the cut-off voltage when you select LiPo battery with the
LEFT and the RIGHT button.
Select how to cut off the power when voltage of the battery drops
to the set value of cut-off voltage with the LEFT and the RIGHT
buttons.
For 2~4-pole motors, usually we recommend 0~5°
Set the value within the range shown below.

Select the advance timing with the LEFT and the RIGHT buttons.
This is the speed at which the ESC reaches the top speed.
Select the acceleration value with the LEFT and the RIGHT
buttons.
The setting value is 50 or lower in case a motor is turned
ON/OFF by an on-board switch of a transmitter such as gliders.
Drive Frequency
Setting choice : 8kHz / 16kHz / 32kHz
Select the value with the LEFT and the RIGHT buttons.
We recommend 32kHz for 10-pole or less motors.
