Battery Wire Connection---When connecting the battery,
pay attention to polarity: incorrect connection will damage
the ESC and Battery. As shown in the f igure above, connect
the positive (+) wire is connected to (+) battery port, and
the negative (-) wire I s connected to the (-) battery port.
Motor Wire Connection ---1. Sensored Mode :When using a
sensored brushless motor, the three A/B/C ESC wires must
connect to the three A/B/C motor wires correspondingly. It
is necessary to connect the Sensor wire to the “Sensor”
socket on the ESC. Don’t change the wires sequence
optionally. 2. Sensorless Mode: When using a sensorelesss
brushless motor, the #A, #B, #C wires of the ESC can be
connected with the motor wires freely (without any sequence).
If the motor runs in the opposite direction, please swap any
two wire connections.
Receiver Wire Connection---The signal wire supplies 6.0V to
the receiver, servo, etc. So there is no need to connect an
additional battery. External power connected to the receiver
may damage the ESC.
1. Connect the ESC with the battery and receiver well, then
turn on the transmitter.
2. Press and holding the power button until the blue LED is
on solid, the motor have a long beep at the same time,
then release the power button, the red led will be on solid,
the ESC enters to the calibration mode.
3. Pull the throttle trigger to the full throttle position, the
blue led blinks three times and the motor beeps once, the
full throttle position is saved.
4. Push the throttle trigger to the full brake position, the
blue led blinks three times and the motor beeps twice, the
full brake position is saved.
5. Release the throttle trigger to the neutral position, the
blue led blinks three times and the motor beeps three
times, the throttle calibration is completed.
6. The ESC can support reverse throttle calibration, if the
transmitter throttle set reverse (it means pull the throttle
will go to 1000 throttle position/normally is 2000, and push
the t hrottle will go to 2000 throttle position/normally is
1000), then you do the throttle calibration the same way as
usual (as above), it will not have any effects on the ESC for
ward and revers way even if the transmitter throttle set
Power On/Off ESC---1. Press the power button then the ESC will
be powered on. 2. Press and holding the power button until the
all LEDs died out, then the ESC will be powered off. (Note: Please
place the throttle trigger on the neutral position: within 10%,
otherwise the ESC can not be powered off.)

The RED LED is always on solid once the power button is
pressed.
The RED LED blinks, single f lash between every one second.
Repeat like “ ¤ ¤ ¤”indicates that the voltage is abnormal.
The RED LED blinks , double f lash between every one
second . Repeat like “ ¤¤ ¤¤ ¤¤ ” indicates that the
temperature is abnormal.
The RED LED blinks, single and double f lash alternately
between every one second. Repeat like “ ¤ ¤¤ ¤ ¤¤ ¤ ¤¤”
indicates that both of the voltage and t emperature is
abnormal at the same time.
The RED LED will not have any responds even the voltage
or temperature is abnormal if not detect the signal.
The BLUE LED blinks , double f lash between every two
seconds . Repeat like “ ¤¤ ¤¤ ¤¤ ” indicates that the
throttle is abnormal. ( No throttle , or the throttle is not on
the neutral position)
Throttle Signal
1. The ESC can support the 450Hz maximum PPM throttle
signal.
2. The ESC throttle protection will be activated under the
following situation, and the BLUE LED blinks double f lash:
The throttle trigger do not place on the neutral position
when the ESC turns on.
Lost the throttle signal.
3. If the ESC lost throttle signal during the operation, the
BLUE LED will blink double f lash, and the ESC will start to
work again until the throttle signal is back to normal.

Boost & Turbo
1. The sensore mode is activated once the ESC detected the
hall sensor signal at any time.
2. The ESC will work on sensorless mode once the ESC didn’t
detect the hall sensor signal at any time.
3. The ESC will have a slight power drop and restored soon
during the moment of sensored and sensorless mode switching.
4. The PWM driving frequency will be selected automatically
by the ESC on sensorless mode, and the manual setting is invalid.
5. It is invalid to set the brake PMW frequency less than 1KHz and
forced recognized as 1KHZ, if the ESC is on sensorless mode.
6. Boost and turbo functions are out vailable on sensorless mode.
Sensored & Sensorless
1. After the boost or turbo timing triggered, the RPM and
current will be increased, and the battery /ESC /motor will
be heating , so setting the proper timing and timing
increased rate, and control the time of timing will ef fect
the battery/ESC/motor service life.
2. The dif f erence of the Boost and Turbo Timing:
The Boost timing will be triggered even though you do not
pull the throttle trigger to the full throttle position.
The Turbo timing will be triggered only when you pull the
throttle trigger to the full throttle position.
3. The Boost timing plus the Turbo timing is equal to the
f inal opened timing when the throttle reaches its maximum
position, and the f inal total timing is 60 degree（for Beast
Pro 150A total timing is 15 degree). For example: If Boost
timing set at 45 degree, and Turbo Timing set at 50 degree,
so when the throttle reaches its maximum position, the
Boost timing will be 45 degree, and Turbo Timing only can
be opened at 15 degree.
4. If set the low voltage or over temperature protection, and
the protection is activated, then all the timing will be closed.
Protection
1. High Voltage Protection:
If the ESC detected the voltage too high(Higher than the
esc standard voltage ) , when the ESC turns on, and the
voltage protection was not set “OFF”, then the voltage
protection will be activated, and the maximum throttle
output will be limited within 50 % . ( The high voltage
protection only worked on the moment of the ESC turns
on , and it will not work on the other stages even it
detected the high voltage , once the high voltage
protection opened, even though the voltage comes down
to the normal voltage, the protection will not be relieved.)
2. Low Voltage Protection:
If the ESC detected the voltage less than the set value at
anytime, and this voltage keep for a while, then the low
voltage protection is activated, and the maximum throttle
output will be limited within 50%.(Once the low voltage
protection activated, even though the voltage comes back
to normal, the protection can not be relieved.)

3. Thermal Protection:
The output throttle from the ESC will be limited (not over
50 % ) with the thermal value you have preset . ( The
Thermal protection will be dismissed when the ESC
temperature drop to 65℃)
4. If t he voltage protection and temperature protection
set off, and when the voltage and temperature become
abnormal , the LED status will indicates the problems
correspondingly , but will not limit the throttle output
and will not close all ESC timing.
5. If the ESC detected the motor have the driving
problem ( like motor rotor locked or motor phase lost
problem) which can cause the motor not run smoothly,
and when the throttle trigger leave neutral position
for a while, then the ESC driving abnormal protection
will be activated, and the motor will emit special tone
like beep-beep-beep ( note: some motors can not beep
or beep with a low sound if motor have phase loss
problem ), and the protection will be closed until you
released the throttle trigger to neutral position for 0.2
seconds. If this problem occurs three times continuously,
then you have to solve the motor driving problem rst,
or the protection will exist all the time.
2. With RCOMG Bluetooth, connected the RCOMG app
to the ESC, the user can program parameters, upgrade
f irmware and check the real-time data of the ESC on the
APP.
3. Due to the range limit of Bluetooth, the operational
distance is around 10 meters.(If there are many metals or
other strong interference signals or obstacles around
will short the operational distance)
4. The Bluetooth name can not be changed.
5. The Bluetooth connecting will be failed during the
ESC throttle calibration process.
Bluetooth
1. Reset password : When the ESC turns on, press and
holding the power button around 10 seconds, the ESC will
restore the Bluetooth password to default setting 0000.
1. The user can program parameters at any status if the
ESC turns on, and new programmed parameters will be
took effect immediately, no need to restart the ESC, it
means the programming parameters can be competed
online, so it can provide a very intuitive feeling between
the before programming and after programming.
There will be some impacts on the battery/ESC/motor
if you program some parameters when the motor in a
high-speed rotation. For example, if you changed the
motor rotation when the motor in a high-speed rotation,
then the ESC will drive the motor reverse immediately,
but the motor can not be reverse immediately because
of its inertia, then it will cause a big current and vibration.
Or when the Boost or Turbo timing opened, but you set
Programmable Items

it of fwhen the motor in a high-speed rotation, it also will cause a big current, so we would like to
recommend not programming parameters when the motor in a high-speed rotation.
2. The programming parameters are saved in the ESC embedded f lash memory, and the f lashed
card have a limited programming life ( around 10K times), so don’t program the ESC very often.
Real-time Data
1. The real - time data can be
read only when the ESC have
the throttle signal. 2. The real- time data is just a
reference data with ± 10 %
accuracy , if you want to get
the more accurate real - time
data , you need to use the
more professional equipment.

SECTION
THROTTLE
BRAKE
It indicates how often the ESC performs throttle adjustment.
When the throttle value changes from high to low, it will decrease every 0.01 second.For example: the current throttle stick is at 80%, and the next
moment is at 30%. If the throttle coast is not turned on, the throttle value will be immediately reduced from 80% to 30%. If it is turned on, the
throttle value will be 80%, 70%... 30% dropped so slowly. Note: If the throttle stick is at 0% at the next moment, the throttle value will be equal to 0
immediately. This item only works within the forward throttle range, and has the most obviouse ef fect at 30% throttle.
Throttle midpoint width, the range of the throttle stick in the centered state.
The minimum throttle, limit the throttle value can not be too small, this item can be adjusted according to the RC car conf iguration, the smaller
the lighter car, this item can be adjusted down, so that the RC car can get a very low speed, the larger the heavier car, this item can be adjusted
large, it can eliminate the jitter caused by insuf icient starting power.
Throttle minus, decay the throttle value. For example, if the throttle stick is at 20%, if the decay is not turned on, the throttle value is 20%.
After setting it to 1% decay, the output throttle value is 20% * (1-1%) = 19.8%. This item only works within the forward throttle range.
For example, if it is set to 50%, it means that the throttle below 50% will be used for throttle Minus. This item only works within the forward
throttle range.
If it is set to 80%, the actual throttle value is 80% when the throttle stick is at 100% of the forward throttle.
If it is set to 80%, the actual throttle value is 80% when the throttle stick is at the 100% position of the throttle in the reverse direction.
It indicates how often the ESC will perform the brake adjustment.
It limits the minimum braking force.
If the minimum braking force is set larger than the maximum braking force, the maximum braking force is equal to the minimum braking force.
It refers to the braking force when the throttle stick returns to the 0% position from the forward stroke after the RC car moves for ward.
If it is turned on, the ESC will turn on correspond brake force when the throttle stick at the 0% position.

Brake PWM frequency.
Turn on the timing to make the motor get a higher speed.
Boost trigger mode includes throttle trigger and RPM trigger.
For example, Boost timing is set to 30 degrees, 50% throttle threshold triggers Boost, then the throttle stick reaches 50% position to enable
Boost timing, and when the throttle stick reaches 100%, 30 degree timing is enabled. The timing value increases linearly from 50% to 100% throttle.
The Boost RPM triggers the threshold. When the motor reaches the RPM threshold, the set boost timing will be fully turned on.
The rate at which the boost timing is reduced to 0 when the boost trigger condition is no longer met.
Turbo timing is the timing that starts when the throttle stick reaches 100%.
For example, set the boost timing to 30 degrees, 50% of the throttle triggers Boost, the initial angle is 2 degrees, when the throttle is at 50%,
the actual boost angle is 2 degrees (if the initial angle higher than the boost timing, then the Þnal angle is the Boost timing initial value).
For example: set the Boost timing to 30 degrees, and the throttle triggers Boost. If the throttle value is instantly increased to 100%, the Boost
timing will not reach 30 degrees immediately, but will increase to 30 degrees at the set increasing speed; It is the same when it is set to RPM trigger.
The speed with the Turbo timing increasing. For dierent motors, if the speed is set too fast, there will be large burst current and the motor will
vibrate violently.

The update time point of the delay. When the timing has been triggered, if the throttle leaves 100% and quickly returns to 100%, whether to delay again or
not. Wait: wait until the timing is reduced to 0, then update the delay, and then re-delay; Instant: update the delay as soon as the throttle leaves 100%, and
start the re-delay immediately.
The speed with the turbo timing decreasing. When the throttle stick leaves the 100% position, the conditions for turning on Turbo are no longer met, but the
Turbo timing will not be immediately reduced to 0, but will decrease at the set speed. When the Turbo is turned on, the motor speed is very fast. If the Turbo
timing value quickly decreases to 0 at this time, the speed decreases too fast, the motor will vibrate severely and reverse high voltage, so please choose the
appropriate timing to reduce the speed.
Turbo delay refers to a delay after the throttle stick reaches 100% before turning on Turbo.
The drive PWM frequency refers to the PWM frequency used when the ESC drives the motor. The lower frequency, the higher acceleration, but the linearity of
the throttle becomes worse and feel aggressive throttle feeling. The Higher frequency ,the smoother throttle feeling, but it will cause the temperature of the
ESC to rise too fast.
In some RC cars, under the default rotation, forward and backward are reversed. At this time, setting another motor rotation can correct this error.
Set the correct number of motor poles to get the correct Boost RPM trigger threshold. At the same time, players can see the correct motor RPM in the
real-time data of the mobile phone APP.
Running mode includes Forward/Brake, Forward/Brake/Reverse, Forward/Reverse.

If the ESC detected the voltage less than the set value at anytime, and this voltage keep for a while, then the low voltage protection is activated, and the
maximum throttle output will be limited within 50%.(Once the low voltage protection activated, even though the voltage comes back to normal, the
protection can not be relieved.)
The output throttle from the ESC will be limited (not over 50%) with the thermal value you have preset.(The Thermal protection will be dismissed when
the ESC temperature drop to 65℃)
