Note: “Forward/Reverse with Brake” mode and 'Foward with Brake' mode uses “Double-click”
method to make the car go backward. When you move the throttle stick from forward zone to
st
“click”), the ESC begins to brake the motor, the motor
speeds down but it is still running, not completely stopped, so the backward action is NOT
When the throttle stick is moved to the backward zone again (The 2
“click”), if the motor speed is
slowed down to zero (i.e. stopped), the backward action will happen. The “Double-Click” method
can prevent mistakenly reversing action when the brake function is frequently used in steering.
By the way, in the process of braking or reversing, if the throttle stick is moved to forward zone,
“Forward/Reverse” mode uses “Single-click” method to make the car go backward. When you
move the throttle stick from forward zone to backward zone, the car will go backward
immediately. This mode is usually used for the rock crawler.
2.2. Drag Brake Force: Set the amount of drag brake applied at neutral throttle to simulate the
slight braking eect of a neutral brushed motor while coasting.
2.3. Low Voltage Cut-O: The function mainly prevents the lithium battery from over discharging.
The ESC detects the battery’s voltage at any time, if the voltage is lower than the threshold for 2
seconds, the output power will be reduced 70%, after 10 seconds the output power will be
completely shut o and the red LED ashes in such a way: “☆-☆-, ☆-☆-, ☆-☆-”.
Please stop your car at the track side as soon as possible to avoid obstructing other racing cars.
Please note that the cuto threshold value in the programmable item list is calculated for Lipo
battery cell, so for NiMH battery packs, if the voltage of the whole NiMH battery pack is higher
than 9.0V, it will be considered as a 3 cells lithium battery pack; If it is lower than 9.0V, it will be
considered as a 2 cells lithium battery pack. For example, a NiMH battery pack is 8.0V, and the
threshold is set to 2.6V/Cell, so it will be considered as a 2 cells lithium battery pack, and the
low-voltage cut-o threshold for this NiMH battery pack is 2.6*2=5.2V. There are 6 preset options
for this programmable item. You can customize the cuto threshold by using the Multifunction
LCD Program Box (Optional equipment) to trim it with a step of 0.1V, so it will be more suitable for
all kinds of batteries (NiMH, NiCd, Li-ion, Lipo, LFP, etc).
Please always keep in mind that the customized value is not for each Lipo battery cell, it is for
2.4. Start Mode (Also called “Punch”): Select from “Level1” to “Level9” as your like, Level1 has a very
soft start eect, while level9 has a very aggressive start eect. From Level1 to Level9, the start force
is increasing. Please note that if you choose “Level7” to “Level9” mode, you must use good quality
battery pack with powerful discharge ability, otherwise these modes cannot get the burst start
eect as you want. If the motor can not run smoothly (the motor is trembling), it may caused by the
weak discharge ability of the battery pack, please choose a better battery or increase the gear rate.
2.5. Maximum Brake Force: The ESC provides proportional brake function. The brake force is
related to the position of the throttle stick. Maximum brake force refers to the force when the
throttle stick is located at the top point of the backward zone. A very large brake force can shorten
the brake time, but it may damage the driverline.
2.6. Maximum Reverse Force: Sets how much power will be applied in the reverse direction.
2.7. Initial Brake Force: It is also called “minimum brake force”, and it refers to the force when the
throttle stick is located at the initial position of the backward zone. The default value is equal to the
drag brake force, so the brake eect can be very smoothly.
2.1. Running Mode: With “Forward with Brake” mode, the car can go forward and brake,
but cannot go backward, this mode is suitable for competition; “Forward/Reverse with Brake” mode
provides backward running function, which is suitable for daily training.
At any time when the throttle is located in neutral zone (except in the throttle calibration or
parameters program process), hold the “SET” key for over 3 seconds, the red LED and green LED will
ash at the same time , which means each programmable item has be reset to its default value.
2.6. Maximum Reverse Force: Sets how much power will be applied in the reverse direction.
2.7. Initial Brake Force: It is also called “minimum brake force”, and it refers to the force when the
throttle stick is located at the initial position of the backward zone. The default value is equal to the
drag brake force, so the brake eect can be very smoothly.
2.8. Throttle Neutral Range: Please refer to the following picture to adjust the neutral range as you like.
2.9. Timing: The 'timing' item is usable for both sensored and sensorless brushless motors.

higher power output, but the whole eciency
Note: For ESC rmware later than 091218A, if
don't choose timing values larger than 18.75°, otherwise the motor maybe over heat and damaged.
2.10. Over-Heat Protection: If the function is activated, the output power will be cut-o when the
temperature of the ESC or the internal temperature of the sensored brushless motor is up to a
factory-preset value for 5 seconds. When the protection happens, the Green LED will ash.
● When the ESC is over-heat: The Green LED ashes as “☆-, ☆-, ☆-” (Single ash).
● When the motor is over-heat: The Green LED ashes as “☆-☆-, ☆-☆-, ☆-☆-” (Double ash).
Note: The motor over-heat protection function is only available for the sensored brushless motor made
by the same manufacturer of the ESC. For motors made by other manufacturers, this function maybe
not available or the protection point doesn’t match the design of the ESC, please disable the over-heat

1. Connect the ESC, motor, receiver, battery and servo correctly.
When using brushless motor with Hall Sensor，it is necessary to connect the sensor cable to the
“SENSOR” socket on the ESC, and ESC can automatically identify the motor type (sensored or
sensorless) by detecting the signal coming from the SENSOR socket.
WARNING! For sensored brushless motor, the #A, #B, #C wires of the ESC MUST be connected
with the motor wire #A, #B, #C respectively. Do not change the wires sequence optionally!

TROUBLE SHOOTING
1. Input voltage abnormal alert tone: the ESC begins to check the input voltage when power on,
if the voltage is out of the normal range, such an alert tone will be heard: “beep-beep-,
beep-beep-, beep-beep-” (there is 1 second interval between every “beep-beep-” tone).
2. Throttle signal abnormal alert tone: when the ESC can’t detect the normal throttle signal, such an
alert tone will be heard: “beep-, beep-, beep-” (there is 2 seconds interval between every “beep-”
3. The led status in normal running
● Normally, if the throttle stick is in the neutral range, neither the red led nor the green led lights.

PROGRAM METHODS
1. Program the ESC with LED program box (Optional equipment )
Please refer to the user manual of LED program box.
2. Program the ESC with Multifunction LCD program box (Optional equipment )
Please refer to the user manual of LCD program box.
3. Program the ESC with the SET button on the ESC
Please refer to the instructions at the right side.
● In the program process, the motor will emit “Beep” tone at the same time when the LED is ashing.
● If the “N” is bigger than the number “5”, we use a long time ash and long “Beep---” tone to
represent “5”, so it is easy to identify the items of the big number.
“A long time ash + a short time ash” (Motor sounds “Beep---Beep”) = the No. 6 item
“A long time ash + 2 short time ash” (Motor sounds “Beep---BeepBeep”) = the No. 7 item
“A long time ash + 3 short time ash” (Motor sounds “Beep---BeepBeepBeep”) = the No. 8 item

2. Throttle Range Setting (Throttle Range Calibration ).
In order to make the ESC t the throttle range, you must calibrate it when you begin to use a new
ESC, or a new transmitter, or change the settings such as the neutral position of the throttle stick,
ATV or EPA parameters, etc. Otherwise the ESC can not work properly. There are 3 points need to be
set, they are the “Top point of forward”, the “Top point of backward” and the “Neutral point”.
The following pictures show how to set the throttle range with a Futaba
transmitter.
A. Switch o the ESC, turn on the transmitter, set the
throttle trim to “0”, set the “EPA/ATV” value of throttle
channel to “100%”, and disable the ABS function of
B. Switch on the ESC when holding the running
soon as possible when the red LED begins to ash.
Note: If you don’t release the “SET” key as soon as the
program mode, in such a case, please switch o the
ESC and re-calibrate the throttle range again from
