*Size and weight are for reference only and may slightly vary
BEC: Means there is a regulator that steps down the input battery voltage to power the receiver and
everything that plugs into the receiver. SBEC & UBEC are a type of BEC.
UBEC: Switching power regulator, very efficient, and produces minimal heat.
SBEC: Linear power regulator, most common in ESCs, not as efficient, and produces a lot of heat
OPTO: No BEC is provided and a separate BEC is required to power the receiver
02 Product Specifications

*Please ensure all solder joints are insulated with heat shrink where necessary.
When using the ESC for the first time or switching transmitters a “Throttle Range
Calibration” procedure will need to be done. This will set the minimum and maximum
throttle range for the ESC and will ensure a stable linear throttle response.

1. Programming the ESC using the transmitter
There are five different types of tones symbolized by a letter e.g. "A", “B”, etc. Once
you enter the ESCs programming mode, the ESC will consecutively go through the
programmable settings starting with parameter #1 through parameter #22 and will not
repeat. To recycle through the parameters, repower the ESC. To determine which
parameter the ESC is currently selecting, listen to the tone sequence. When the
parameter is selected you can activate it by moving throttle to the zero-throttle position.
You can alternatively check out our programming videos (May not be available yet).
An Example on how to turn the brake on/off
Turn on the transmitter and move the throttle to the full throttle position. Powerup the
ESC and wait a couple of seconds. The ESC may make a short beep. Wait for the ESC
to make “A –A –A –A” set of tones which is four short beeps. This indicates that IF
the throttle stick was moved the zero-throttle position it would do a throttle range
calibration. However, this isn’t the desired setting to be changed. The brake setting is
parameter #2 which means to change the setting we’ll need to wait for the second set
of tones to complete. So, we’ll wait a couple more seconds until the ESC makes a “B –

B –B –B” set of tones which is four sets of three continuing beeps. Once it has
finished making the tones move the throttle to the zero-throttle position. If the brake
was off before it’ll turn the brake on and if the brake was on before it’ll turn it off. Wait
for the ESC to beep which confirms that the ESC has saved the new settings. Now
unplug the ESC and it’ll be ready for use. If other settings are desired to be changed
simply repeat the procedure for each setting individually.
2. Programming the ESC using the programming card
To program the ESC using the programming card is simple.
1. Throttle Range Calibration: See “1. Throttle Range Calibration” under “04 First
Time Use”
2. Brake: On / Off
On:The propeller will stop immediately when the throttle stick is moved to the
neutral position.
Off: The propeller with be able to freely spin when the throttle stick is moved to
the neutral position.
3. Battery type LiPo / Li-ion or NiMH / NiCad
NiMH / NiCad: Set protection point for NiCad / NiMH battery type.
*Note: The selection of NiMH / NiCad battery will make the ESC automatically set the
cutoff voltage at 65% (Factory default). The cutoff voltage can be modified through the
low voltage parameter. When the NiMH / NiCad battery connects to the ESC, the ESC
will read its initial voltage. The voltage will be used as a reference value for the cutoff
voltage. E.g. 65% of the initial voltage.
LiPo / Li-Ion: Set protection point for LiPo / Li-Ion battery type and detect
number of cells automatically in the battery pack. Cutoff voltage will be based on the set
cutoff voltage parameter and can be modified through the cutoff voltage parameter.
4. Battery protection: Low (2.8V or 50%) / Medium (3.0V or 65%) / High (3.2V or
75%)
06 Programmable Settings

Ni-xx (NiMH / NiCad) battery pack: Set the cutoffvoltage 50% (Low) / 65%
(Medium) / 75% (High) of the initial voltage (The voltage the ESC reads when the
battery pack is plugged in).
Li-xx (LiPo / Li-Ion) battery pack: Set the cutoff voltage per cell 2.8V (Low) / 3.0V
(Middle) / 3.2v (High). E.g. A 4s battery cutoff voltage will be 11.2V for Low, 12.0V as
Medium, and 12.8V as High.

5. Timing: Automatic / Low / High
Automatic: The ESC will detect the most suitable motor timing
automatically.
Low (7 –22 degrees): Suitable for most inrunner motors.
High (22 –30 degrees): Suitable for most outrunner motors.
*Note: Under most cases, the Automatic setting is suitable for all
motors. However, in order to increase efficiency, we recommend
using low timing for 2 poles (generally inrunner motors) and using
high timing for 6 and more poles (generally outrunner motors). We

recommend using the recommended timing for the motor or
“Automatic” setting when uncertain.
6. Start-up: Very Smooth / Smooth / Accelerated Startup
Very Smooth: 1.5 second linear throttle lag response time between starting the
motor and full motor speed. This setting can prevent a gearbox from stripping under
instantaneous load. This setting is recommended for geared motors or slow startups
Smooth: 1 second linear throttle lag response time between starting the motor
and full motor speed. This setting is recommended for geared motors or slower starups.
Accelerated Startup: Zero throttle lag response time between starting the motor
and full motor speed. This setting is recommended for direct drive motors and zero
delay startups.
7. Helicopter Modes: Off / Mode 1 / Mode 2
Off: Turns off Helicopter Mode.
Helicopter Mode 1: Delays throttle response time between zero-throttle position
and full throttle position by 5 seconds.
Helicopter Mode 2: Delays throttle response time between zero-throttle position
and full throttle position by 15 seconds.
*Note: This mode is slightly different then the Start-up mode. It’ll only delay the
throttle lag response time when the throttle is in the zero-throttle position for a few
seconds and then the throttle stick in immediately moved the full throttle position.
Otherwise the throttle will respond normally based on the programmed “Start-up”
parameter. If the Helicopter Mode is turned on the “Brake” setting will be reset to “Off”
and the “Protection Mode for Low Voltage” setting will be reset to “Reduce Power”.
8. Motor Rotation Direction: Clockwise / Counterclockwise
*Note: The motor rotation direction can be reversed by swapping any two of the
three bullet plug connections. However, if you’ve soldered the connection between the
ESC and Motor you can alternative program the ESC to reverse the motor direction.
9. PWM Frequency: 8kHz / 16kHz

8kHz: Is the PWM Frequency for a motor with 2 poles, usually an inrunner motor.
However, the 16 kHz frequency can provide more power but will also cause more
Electromagnetic Interference (EMI). Therefore, the default setting is 8kHz.
16kHz: Is the PWM frequency for a motor with more than 2 poles, usually an
outrunner motor.
10. Protection Mode for Low Voltage: Reduce Power / Hard Cutoff
Reduce Power: The ESC will reduce the motors output power when the set
“Low Voltage Protection” mode is reached to protect the battery from over discharging
but still giving enough power to return the ESC. This parameter is recommended.
Hard Cutoff: The ESC will completely shut off the motors ouput power when the
set “Low Voltage Protection” mode is reached to protect the battery from over
discharging.
Start-up Protection
If the motor fails to startup normally in two seconds after push the throttle to start the ESC will
cut off the motor. The throttle shall be reset to commence a restart. Possible reasons: there is a
disconnection or poor contact in wiring between the ESC and motor. The propeller is stemmed
by other objects. The speed reduction gear is badly blocked.
Overheat Protection
When the working temperature in the ESC is higher than 100℃, the ESC will reduce the output
power automatically to commence protection, but will reduce the output power to 40% of full
power to reserve some power for motor and avoid crash landing instead of turning off all output
power. The ESC will recover to max power as the temperature falls.
Loss of Throttle Signal Protection
The ESC will reduce the output power to motor when the ESC detect that there are 2 seconds'
lost of throttle signals. If there another 2 seconds' lost of throttle signals, the ESC will cut off
motor automatically. If the throttle signals recover during the Throttle Signal reduction of output
power of motor, the ESC will recover control of throttle at once. In this method, in the case of
momentary lost of signals (within 2 seconds), the ESC Loss Protection will not commence the
protection of throttle. Only when the control signals have been lost for a long time, the ESC will
07 ESC Protections

commence protection. However, the ECS will reduce the output power gradually instead of
cutting off output power immediately so that the players will have certain period to rescue the
machine. It has both safety and practicability
Low Voltage Protection
● The warning tone: The warning tone is set as audible sound to help users judge abnormal
condition after turn on the power. 1. Fail to enter working mode after turn on the power: the
routine of throttle has not been set yet. 2. Continuing beeps: the pull rod of throttle is not in the
lowest position. 3. There is a short pause after a beep: the ESC can not detect normal throttle
signals from receiver. 4. There is a pause of one second after a beep: the voltage of battery pack
is out of acceptable limit (once the battery is connected, the ESC will carry out a self-checking
and check the voltage of battery.)
Please pay attention to the following safety information when using. ● Never disassemble any
electro components in the ESC by yourself, or permanent damages or lost of information will
occur. ● Check the setting of receiver. Do not install propeller or small driving gear on motor if
you haven't confirm that the setting of receiver is correct when test the ESC and motor for the
first time. ● Do not use cracked or broken battery pack. ● Do not use battery pack easily get
overheat. ● Do not use short-cut battery. ● Do not use cable insulation material against
standards. ● Do not use cable connector against standards. ● The number of battery or servo
system shall not exceed the rules for ESC. ● The voltage of battery shall not exceed the scope of
working voltage of ESC. ● Pay attention to the polarities of battery. Wrong polarities will
damage the ESC. ● Be sure that the ESC will not use in manned craft or other manned machines.
● Do not place the ESC in moist or over exposure. ● Do not take out battery when the motor is
working, for the generated large peak current will damage the ESC. ● Do not pack anything
outside the ESC. Install the ESC in places with good ventilation and heat dissipation as far as
possible.
