【SPECIFICATIONS】
【BEGIN TO USE THE NEW ESC】
WARNING! THIS BRUSHLESS SYSTEM IS VERY POWERFUL! FOR SAFETY, PLEASE ALWAYS KEEP THE
WHEELS AWAY FROM THE TRACK WHEN YOU BEGIN TO SWITCH ON THE ESC.
1. Connect The ESC, Motor, Receiver, Battery And Servo
A) Sensored brushless motor wiring
When using brushless motor with Hall Sensor，it is necessary to connect the sensor cable to the
“SENSOR” port on the ESC, and ESC can automatically identify the motor type (sensored or sensorless)
by detecting the signal coming from the SENSOR port.
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!
B) Sensorless brushless motor wiring
When using brushless motor without Hall Sensor, 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.
2. Throttle Range Setting (Throttle Range Calibration)
In order to make the ESC fit the throttle range, you must calibrate it when you begin to use a new ESC, or a new
transmitter, or change the settings of neutral position of the throttle stick, ATV or EPA parameters, etc. Otherwise
the ESC cannot work properly.
There are 3 points need to be set, they are “Top point of forward”, “Top point of backward” and the neutral point.
The following pictures show how to set the throttle range with a FutabaTM transmitter.
Note2: If you don’t release the “SET” key as soon as the red LED begins to flash, the ESC will enter the program
mode, in such a case, please switch off the ESC and re-calibrate the throttle range again from step A to step D.

Options
C) Set the 3 points according to the steps
shown as the pictures on the right side.
1) The neutral point
Move the throttle stick at the neutral point,
and then click the SET key, the green LED
flashes 1 time.
2) The end point of forward direction
Move the throttle stick at the end point of
forward direction, and then click the SET
key, the green LED flashes 2 times.
3) The end point of backward direction
Move the throttle stick at the end point of
backward direction, and then click the SET
key, the green LED flashes 3 times.
D) Throttle range is calibrated; motor can be
started after 3 seconds.
“Double-Click” method prevents mistaken reversing action when the brake function is frequently used in steering.
By the way, in the process of brake or reverse, if the throttle stick is moved to forward zone, the motor will run
forward at once.
“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
effect of a neutral brushed motor while coasting.
2.3. Low Voltage Cut-Off: The function prevents the lithium battery pack 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 will be completely stopped, and the red LED flashes in such a way:
3. Check 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.
► The red LED lights when the car is running forward or backward and it will flash quickly when the car is braking.
► The green LED lights when the throttle stick is moved to the top point of the forward zone.
4. Check The Lipo Cells Setting If You Are Using Lithium Battery
If you are using Lipo battery, we strongly suggest setting the “Lipo Cells” programmable item manually to avoid the
over-discharge problem. Please read the instructions on page 3.
In normal case, when the ESC is switched on, the motor will emit several “Beep” tones to express the cells amount
of the battery pack. For example, “Beep-Beep-” means 2s Lipo, “Beep-Beep-Beep-” means 3s Lipo, etc.
【PROGRAM THE ESC】
1. Programmable Items List (The italics texts in the form are the default settings)
“☆-☆-, ☆-☆-, ☆-☆-”.
There are 6 preset options for this item. You can customize the cutoff threshold by using an advanced 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 cell, it is for
the WHOLE battery pack.
2.4. Start Mode (Also called “Punch”): Select from “Level1” to “Level9” as your like, Level1 has a very soft
start effect, while level9 has a very aggressive start effect. 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 effect as you want. If the motor cannot 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 (Use a smaller pinion).
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 gears. The
“Disable” option inhibits the inherent brake function of the speed controller. When this option is selected, the brake
function is realized by a traditional disc-brake system driven by a servo.
2.6. Maximum Reverse Force: Sets how much power will be applied in the reverse direction. Different value
makes different reverse speed.
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
effect can be very smoothly.
2. Explanation For Each Programmable Item
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 function, which is
suitable for daily training.
Note: “Forward/Reverse with Brake” mode uses “Double-click” method to make the car go backward.
When you move the throttle stick from forward zone to backward zone for the 1st time (The 1st “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 happened immediately. When the throttle stick is moved to the backward zone for the 2nd time (The
2nd “click”), if the motor speed is slowed down to zero (i.e. stopped), the backward action will happen. The
2.8. Throttle Neutral Range: Please refer to the following picture to adjust the neutral range as your like.
2.9. Timing: There are many differences among structures and parameters of different brushless motors, so a
fixed timing ESC is difficult to compatible with all brushless motors. It is necessary to make the timing value
programmable. Please select the most suitable timing value according to the motor you are just using. Generally,
higher timing value brings out higher power output, but the whole efficiency of the system will be slightly lower down.
2.10. Over-Heat Protection: If the function is activated, the output power will be cut-off when the temperature of
the ESC or the internal temperature of the sensored brushless motor is higher than a factory-preset value for 5
seconds. When the protection happens, the Green LED will flash.
(Note: The over-heat protection function is permanently enabled by the manufacturer).
When the ESC is over-heat: The Green LED flashes as “☆-, ☆-, ☆-”.
When the motor is over-heat: The Green LED flashes as “☆-☆-, ☆-☆-, ☆-☆-”.
Note3: The motor over-heat protection function is only available for the sensored brushless motor made by the
Page 3
User Manual of 80A and 150A Brushless ESC for 1/8 Scale Car HW-SM505ENG-20130417 Page 3 of 4
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.
2.11. Motor Rotation: You can use this item to change the rotation direction. Face to the motor shaft (That means
the rear cover of the motor is far from your face), and move the throttle stick to the top point of the forward zone. If
this item is set to “CCW”, the shaft runs counter-clockwise; If this item is set to “CW”, the shaft runs clockwise.
2.12. Lipo Cells: We strongly suggest setting the “Lipo Cells” item manually. Because the normal voltage of each
Flow chart: Program the ESC with the SET key
Lipo cell varies from 2.6V to 4.2V, it is quite difficult to calculate the cells number of a discharged Lipo battery pack.
If it is calculated incorrectly, the Low Voltage Cutoff Protection function may work abnormally, so the option “Auto
Calculate” is only available for 2s, 4s and 6s Lipo. If the voltage of the battery pack is lower than 8.8V, it is judged as
a 2s Lipo; If the voltage is between 8.8V to 17.6V, it is judged as a 4s Lipo; If the voltage is higher than 17.6V, it is
judged as a 6S Lipo. So in order to make the Low Voltage Cutoff Protection function always works correctly, please
set the “Lipo Cells” item manually.
3. Program Methods
A) Program the ESC with LED program card (Optional equipment )
Please refer to the user manual of LED program card.
B) Program the ESC with advanced LCD program box (Optional equipment )
Please refer to the user manual of LCD program box.
C) Program the ESC with the SET button on the ESC
Please refer to the instructions at the right side.
4. Reset All Items To Default Values
At any time when the throttle is located in neutral zone (except in the throttle calibration process or ESC program
mode), hold the “SET” key for over 3 seconds, the red LED and green LED will flash at the same time , which
means each programmable item has be reset to its default value.
【ALERT TONES】
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 group of “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-” tone).
Note4:
In the program process, when the LED is flashing, the motor will emit “Beep” tone at the same time.
If the number “N” is bigger than the “5”, we use a long time flash and long “Beep---” tone to represent “5”, so it
is easy to identify the items with bigger series number.
For example, if the LED flashes as the following:
“A long time flash + 1 short time flash” (Motor sounds “Beep---Beep”) = the No. 6 item
“A long time flash + 2 short time flashes” (Motor sounds “Beep---BeepBeep”) = the No. 7 item
“A long time flash + 3 short time flashes” (Motor sounds “Beep---BeepBeepBeep”) = the No. 8 item
……
And so on.

Trouble
Possible Reason
Solution
After power on, motor doesn’t work,
and the cooling fan doesn’t work
The connections between
battery pack and ESC are not
correct
Check the power connections
Replace the connectors
After power on, motor can’t work,
but emits “beep-beep-, beep-beep-”
alert tone. (Every group of
“beep-beep-” has a time interval of
1 second )
Input voltage is abnormal, too
high or too low
Check the voltage of the battery pack
After power on, red LED always
lights, the motor doesn’t work
Throttle signal is abnormal
Plug the control wire into the throttle
channel of the receiver correctly.
The motor runs in the opposite
direction when it is accelerated
1)The wire connections between
ESC and the motor are not
correct
2)The chassis is different from
the popular design
1) For sensorless motor: Swap any two
wire connections between the ESC and
the motor. Or use the method #2
2) For sensored motor: Please check
the wire connections, they must be A-A,
B-B, C-C respectively. If the connections
are correct, please change the “Motor
Rotation” programmable item to
“CW(Clockwise)”
The motor suddenly stops running
while in working state
The throttle signal is lost
Check the transmitter and the receiver
Check the signal wire from the throttle
channel of your receiver
The ESC has entered the Low
Voltage Protection Mode or
Over-heat Protection Mode
Red LED flashing means Low voltage
protection. Green LED flashing means
Over-heat protection
When accelerating quickly, the
motor stops or trembles
1) The battery has a bad
discharge performance
2) The gear rate is too small
3) The “Start Mode (Punch)” of
the ESC is too aggressive
1) Use a better battery
2) Use lower KV motor or change the
gear rate, choose smaller pinion
3) Select a softer option for the “Start
Mode (Punch)”
When the throttle stick is in the
neutral range, the red LED and the
green LED flashes synchronously
The motor is a sensored motor,
but the ESC detects abnormal
signal from the sensor, so it
changes to sensorless mode
automatically
1) Check the connection of Hall sensor
cable to make it firmly connect the motor
with the ESC
2) The Hall sensors in the motor are
damaged, please change the motor
