ESC specications
1.Startup Procedure
Move transmitter throttle trigger to neutral position > Switch on the transmitter >
Connect battery pack to ESC > System detects the neutral throttle signal, and makes
a long "Beep" tone > System detects battery voltage and makes several short "beep"
tones, which denote the number of battery cells > when self-check is nished > " ♫ 1 2
3" tone should be emitted > ready for start.

2.Setting Throttle Range
Throttle range should be setup when a new transmitter is being used. "SET" key is
to be used for throttle range.
Turn off the ESC > Switch on the transmitter > Press and hold the "SET" key >
Switch on the ESC >Push the throttle trigger to the top point of forward within two
seconds > Wait for one second > System detects maximum throttle signal, and makes
two "beep-" tones. This denotes that max throttle has been conrmed and saved.
Now pull the throttle trigger to the top point of backward > System detects minimum
throttle signal with two "beep-" tones. This indicates that min throttle has been
conrmed and saved > Release the "SET" key > Setting is nished. Throttle trigger
goes back to neutral position. When neutral position is checked, there is a long “beep-
“ tone, it detects the battery voltage. After several short beeps, number of Lipo battery
cells is detected. This indicates that the system is working well. After a short music “♫
1 2 3” is heard, then the vehicle is ready to run.
3. Protection functions
A) Low voltage protection: The default voltage is 0.0V. The system automatically
checks number of Lipo cells and calculates low voltage value. When the power voltage
is lower than the cutoff threshold, ESC will cut off power output automatically.
B) Throttle signal loss protection: The ESC will cut off the motor power within 0.5
second once the throttle signal is lost.
C) Overheat protection: Power output will be reduced to 20% if temperature of the
CPU gets to 100˚C, and the power will resume after temperature gets back to normal
(usually below 100˚C).
D) Self-check: ESC will start self-check when power is on. If self-check fails, ESC
will continuously emit 20 times of short "beeps”.
4. LED indicators:
i) Green LED is on when the vehicle runs. Red LED turns on at reverse. Green and
red LEDs are on during brake. When the vehicle stops, both green and red LEDs are
off.
ii) During over voltage, low voltage or over heat, both red and green LEDs ash. At
over voltage or low voltage, the motors stops, both red and green LEDs ash.
Parameter conguration with LED program card
1. Brake force: There are three options here, 50%, 75%, and 100%. The default is
75%. The ESC provides proportional brake function. The brake force is related to the
position of the throttle trigger. It refers to the maximum brake force when the throttle
trigger is pushed to the end of the backward zone.
2. Drag brake force: Five options. 0%, 5%, 10%, 15%, and 20%. The default is 0%.
When the throttle trigger is located at the neutral zone, the ESC provides a slight brake
force.

3. Run mode: Three options, One, Two and Two2. The default is Two2.
i) One: The vehicle can go forward and brake. It will brake continuously if the throttle
trigger is placed at backward zone.
ii) Two: This is a bi-directional mode. The vehicle goes forward when the throttle
trigger is located at the forward zone. When the throttle trigger is located at the
backward zone, the vehicle will go backward and the brake will occur when direction is
changed. No need to change to neutral position.
iii) Two2: This is the conditional bi-directional mode. The vehicle goes backward only
when it is stopped and throttle trigger is pushed from neutral zone to backward zone.
When the vehicle is running forward, push throttle trigger to backward zone, then the
vehicle will keep brake until it stops, the throttle stick return the neutral zone, and push
the throttle stick to the backward zone, then the car will go backward.
4. Startup power percent (Start Force): The percentage of output power can be
set up as 00%-29% when the vehicle starts. The default value is 20% (automatic
detection). Under default setting, output power is decided automatically by the system
according to throttle position. The more powerful the startup power is, the more current
the motor generates. At normal situation, try to choose relatively small startup power to
reduce motor current. This will greatly protect the ESC.
5.Please refer to < 5. Li-xx cell numbers > in Step 3 for detail.
6. Cut off voltage (low voltage protection threshold): The range is 00.0V to 49.4V.
User can set proper cutoff voltage according to cell quantity. The default is 3.1V.
Note: The system will detect battery cells and calculate proper threshold automatically
if the setting is 3.1V. The protection threshold for each Li-XX cell is 3.1V. For example,
if the Li-XX battery pack is 3 cells, then the cutoff voltage is 3.1V*3 cells=9.3V.
7. Advance timing: There are four options, they are Low, Middle, High and Highest.
The default is Middle. Low advance timing is recommended for high inductance and
low KV motors. High advance timing is recommended for low inductance and high KV
motors.
8. Neutral range: Three options. 6%, 8%, and 10%. The default is 8%. At this zone,
the motor will be turned off. Refer to the throttle diagram.
9. Initial brake force: Four options. 5%, 10%, 20%, and 30%. The default is 5%. It
refers to the brake force when the throttle stick is located at the initial position of the
backward zone.
10. Reverse force: Four options. 25%, 50% 75%, and 100%. The default is 25%. If
refers to force ranges of the vehicle in reverse direction.
Programming the ESC with key

Step 1 Enter program mode
1.Turn off the ESC, Switch on transmitter, keep throttle stick
to the neutral position.
2.Press and hold the "SET" KEY, Switch on the ESC.
3.Wait for 4 seconds, a music tone like "♫ i3i3" should be
emitted , which means program mode is entered.
Step 4 Exit program
There are two ways to exit program mode:
1. In step 2, after 3 long tone (The item #11), release the
KEY within 2 seconds.
2. In step 3, after special tone "♫ 5 6 5 6", release the KEY
within 2 seconds.
Step 2 Select programmable items
After entering program mode, hold the “SET” KEY continuously, you will hear 11 tones and red LED
ashes in a loop in the following sequence. Release the “SET” KEY within 2 seconds after one
tone, this item will be selected, and enter step 3.
(1) “beep-“ (1 short tone, red LED ashes 1 short time) Brake Force
(2) “beep- beep-“ (2 short tones, red LED ashes 2 short times) Drag Brake
(3) “beep- beep- beep-“ (3 short tones, red LED ashes 3 short times) Run Mode
(4) “beep- beep- beep- beep-“ (4 short tones, red LED ashes 4 short times) Start Force
(5) “beep----“ (1 long tone, red LED ashes 1 long time) Li-xx cells
(6) “beep---- beep-“ (1 long 1 short tones, red LED ashes 1 long time and
1 short time) Cutoff Threshold
(7) “beep---- beep- beep-“ (1 long 2 short tones, red LED ash 1 long time and 2 short times) Timing
(8) “beep---- beep- beep- bee (1 long 3 short tones, red LED ashes 1 long
time and 3 short times) Neutral Range
(9) beep---- beep- beep- beep- beep-“ (1 long 4 short tones, red LED ashes 1 long time
and 4 short times) Initial Brake Force
(10) “beep---- beep----“ (2 long tones, red LED ashes 2 long times) Reverse Force
(11) “beep---- beep---- beep----“ (3 long tones, red LED ashes 3 long times)
Restore to default and Exit
Note: One long “beep----“ = 5 short “beeps-“, one long ash = 5 short ashes

Step 3 Set item value
After entering the items, you will hear several tones and green LED ashes in loop,Press the “SET” KEY within 2
seconds after one tone is heard, you will hear “♫ 5 6 5 6”. This indicates that the value is set and saved.
Hold the SET KEY for 3 seconds, you will go back to step 2, which allows you to continue the setup. If the “SET”
key is released within 2 seconds, you will exit the program model right away.

Note:
1- 1 long “beep----“ equals 5 short “beeps-“. For example, in “Li-xx Cells Number” setting, 1 long “beep----“ plus 1
short “beep-“ (5+1=6), which means a 6-cell Li-xx battery pack.
2- The boldface in above table refers to default value.
3- Low voltage Protection threshold (Cutoff voltage) equals Li-xx Cells Number multiplied by Cutoff threshold.
Cutoff threshold is protection threshold for one cell Li-xx. For example, if Li-xx number is 3 cells, and Cutoff
threshold is 3.1V, the cutoff voltage will be 3.1V per cell*3 cells=9.3V.
4- In Step 2, after 3 long tones (Item# 11), if the “SET” key is released within 2 seconds, you will exit the program
mode. If no other item value is selected, the ESC will restore all items to default value, and makes two “beep-“
tones. When other item value is selected, it will not get back to default values.
