Features
High performance microprocessor brings out the best compatibility with all kinds of motors and the highest driving
efficiency.
3 start modes: Normal / Soft / Very-Soft.
Separate voltage regulator IC for microprocessor to get a better anti-jamming capability.
Multiple protection features: Low-voltage cut-off protection.
The output of the built-in BEC 5V.
Program Card is supported. Very easy to program the ESC at home or at the field.
Notice:
The ESC with BEC supply. The output voltage is 5V. The load current is 2A.
The introduction of the connection in the ESC
In order to avoid short circuit and leakage, the joint are connected by thermal shrinkable pipe to ensure insulation.
The function of electric speed controller for brushless motor

1. Reset to factory default.
2. Brake types(OFF/ON).
3. Cut-off Types(Soft-cut/Cut-off).
4. Cut-off Voltage(Low/Middle/High).
5. Start Mode(Normal/Soft/Very-Soft).
6. Timing Mode(Low/Middle/High).
7. Cell(Auto/2/3/4).
The operation steps of programming in ESC for brushless motor
1. Turn off the ESC and disconnect the throttle lead from the receiver.
2. Connect the throttle lead from the ESC to the 3 pin signal connector on the Program Card. (If the ESC
is without BEC, please also connect a 4.8V-6V battery to 3 pin batt.connector.)
3. Turn on the ESC to apply power to both ESC and Program Card.
4. All current settings will be displayed on the correspond LEDs.
5. Press up/down button to move between settings.
6. Press left/right button to change the value for that setting.
7. Press Load Default button to return to default setting (if necessary).
8. Press OK button to save this setting.
9.
Turn off the ESC and disconnect the throttle lead from Program Card and connect it back to the
receiver.
A)
Brake: Off/On
Off: the propeller stops naturally when the throttle works under the smallest position.
On: the propeller stops immediately when the throttle works under the smallest position.
B)
Cut-Off: Soft-cut/Cut-off
Soft-cut: Soft Cut (Gradually reduce the output power)
Cut-off: Immediately stop the output power.
C)
Cut-off Voltage: Low/Middle/High

For normal voltage ESC (supports 2-4 cells Lipo), the Low / Middle / High value for each cell is: 2.85V / 3.15V /
3.30V
D)
Start Mode: Normal/Soft/Very-Soft

The initial acceleration of the Soft and Very-Soft modes are slower than Normal mode, usually it takes 3
second for Soft mode or 8 seconds for Very-Soft mode from 0% throttle advance to full throttle. After startup,
if the throttle is closed (throttle stick is moved to the bottom position) and opened again (throttle stick is moved
upwards) within 3 seconds, the restart will be temporarily changed to Normal mode to get rid of the chances of
a crash caused by slow throttle response. This special design is useful for aerobatic flight.
E)
Timing Mode: Low/Middle/High

Usually, low timing value is suitable for most motors. But there are many differences among structures and
parameters of different motors so please try and select the most suitable timing value according to the motor
you are just using. The correct timing value makes the motor run smoothly. And generally, higher timing value
brings out higher output power and higher speed.
F)
Cell: Auto/2/3/4
For normal voltage ESC (supports 2-4 cells Lipo), the values are Auto / 2S / 3S / 4S.
Recovery to factory default setting

1. Brake: Off
2. Cut-off Type: Cut-off
3. Cut-off Voltage: Middle
4. Start Mode: Normal
5. Timing Mode: Middle
6. Cell: Auto
Setting Throttle Range
1. Disconnect the throttle lead from the receiver.
2. Apply Power to ESC.
3. Full Throttle
4. Connect the Throttle lead to the receiver.
5. One Beep sound.
6. Minimum Throttle.
7. Another Beep sound.
