BEC means “Battery Elimination Circuit”. It is a DC-DC voltage regulator to supply the receiver and other equipments from the main battery pack. With the
build-in BEC of an ESC, the receiver needn’t to be supplied with an additional battery pack.
SAFETY NOTICE INTERNAL BEC:
For safety reason a 4 Cell NiCD/NiMH Battery or a external BEC (Art. Nr. 01.1446) must be installed on the
receiver!
Wiring Diagram
Programmable Items
1. Brake Setting:Off / Soft / Hard / Very Hard, default is Off
2. Battery Type:Lithium (Lipo or Li-ion) / NiMH, default is Lithium
3. Low Voltage Protection Mode (CutOff Mode): Soft Cut (Gradually reduce the output power) / Hard Cut (Immediately stop the
output power). Default is Soft Cut
4. Low Voltage Protection Threshold (Cutoff Threshold): Low / Middle / High / Custom, default is Middle
For lithium batteries, the cutoff threshold of the whole battery pack is calculated according to the cells number.
Low: 2.85V per Cell
Middle: 3.15V per Cell
High: 3.30V per Cell
5.
For NiMH and NiCd batteries, the cutoff threshold of the whole battery pack is calculated as follows:
Low : 50% of the battery’s battery’s full charged voltage
Middle: 62.5% of the battery’s full charged voltage
High: 75% of the battery’s full charged voltage
Start Mode:Normal / Soft / Very-Soft, default is Normal
“Normal” is preferred for fixed-wing aircraft. “Soft” or “Very-Soft” are preferred for helicopters. 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 usedful for aerobatic flight.
6.
2)
Timing:0°/ 3.75° / 7.5° / 11.25° / 15° / 18.75° / 22.5° / 26.25°, default is 15°
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.
2)
After changing the timing setting, please test your RC model on ground prior to flight!
7. Reserved for future
8. Reserved for future
9. PWM Frequency: 12KHz / 8KHz, default is 12KHz
For some motors with high KV (high speed) and many poles, the 12KHz PWM frequency may let them work more smoothly. But the
higher PWM frequency will make the ESC hotter. Generally, the 8KHz PWM frequency is suitable for most motors.
10. BEC Output: 5.25V / 6V, default is 6V
11. Reserved for future.
3)
12. Lipo Cells: Auto / 2S / 3S / 4S / 5S / 6S, the default is Auto
This programmable item is available for lithium battery. In the startup process, the motor will emits several “Beep-” tones to represent
the Lipo cells number, it is helpful for you to check whether it is coincident with the actual battery pack or not.
3)
If you choose “Auto”, the ESC may mistakenly judge the battery cells when the voltage is less than 3.7V/Cell, so we strongly
suggest setting the “Lipo Cells” manually.
Begin To Use The New ESC
Please check the wiring and connections carefully, and then start the ESC in the following sequences:
1.
Move the throttle stick to the bottom position and then switch on the transmitter.
2.
Connect the battery pack to the ESC, the ESC begins the self-test process, a special tone “♪ 123” is emitted, which means the
voltage of the battery pack is in normal range, and then N “Beep” tones will be emitted, means the number of lipo battery cells. Finally
a long “Beep—” tone will be emitted, which means the self-test is OK, the aircraft or helicopter is ready to go flying.

If nothing is happened, please check the battery pack and all the connections;

If a special tone “♪
” is emitted after 2 Beep tones (“Beep-Beep-”), means the ESC has entered the program mode, it is
because the throttle channel of your transmitter is reversed, please set it correctly;

If the red LED flashes very quickly (2 times per second), means the input voltage is too low or too high, please check your
battery’s voltage.
3. VERY IMPORTANT! Because different transmitter has different throttle range, you need to calibrate the throttle range. Please read
the instruction Throttle Range Setting”.
After correctly setting the throttle range, the red LED lights when the throttle stick is moved to the top position (Maximum throttle).
Alert Tone
1. Input voltage is abnormal: The ESC begins to check the voltage when the battery pack is connected, if the voltage is not in the
acceptable range, such an alert tone will be emitted: “Beep-Beep-, Beep-Beep-” (Every “Beep-Beep-” has a time interval of about 1
second), and at the same time, the red LED also flashes.
2. Throttle signal is lost: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “Beep-, Beep-, Beep-”.
(Every “Beep-” has a time interval of about 2 seconds)
3. Throttle stick is not in the bottom position: When the throttle stick is not in the bottom (lowest) position, a very rapid alert tone will be
emitted: “Beep-, Beep-, Beep-”. (Every “Beep-” has a time interval of about 0.25 second.)
Protection Function
1. Abnormal startup protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off the output power. In
this case, the throttle stick MUST be moved to the bottom position again to restart the motor. (This happens in the following cases:
The connection between ESC and motor is not reliable, the propeller or the motor is blocked, the gearbox is damaged, etc.)
2. Over-heat protection: When the temperature of the ESC is to high, the ESC will reduce the output power.
3. Throttle signal loss protection: The ESC will cutoff the output power if throttle signal is lost for more than 0.25 second, the output
power will be resumed as soon as the throttle signal is normal again.
