TROUBLE

 

POSSIBLE REASON

 

SOLUTION

• “Forward with Brake” mode : The car can go forward and brake, but cannot go backward, this 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 first 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 immediate-
ly.When the throttle stick is moved to the backward zone again (The 2nd “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, 
the motor will run forward at once. 
• “Forward/Reverse” mode uses “

Single-click

” to make the car go backward. When you move the throttle stick from forward zone to 

backward zone, the car will go backward immediately. In the process of braking or reversing, if the throttle stick is moved to forward 
zone, the motor will run forward at once.

• Set the amount of drag brake applied at neutral throttle to simulate the slight braking effect of a neutral brushed motor while coasting.

Running Mode

Drag Brake Force

• The function prevents the lithium battery pack from over discharging. The ESC detects the battery’s voltage at any time, if the

Low Voltage Cut-Off

• Select from “ Level1 ” to “ Level9 ” as you like. Level 1 has a very soft start effect, while level 9 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 with powerful discharge ability, otherwise these modes cannot get the burst start effect as you want. If the motor cannot run 
smoothly (that means the motor is trembling), it may caused by the weak discharge ability of the battery, please choose a better one or 
a softer gear ratio.

Start Mode

• 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 end 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 mechanical disc-brake system driven by a servo.

Maximum Brake Force

Program the ESC with the SET button on the ESC

Program the ESC with the LED program box

• 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 flash at the same time , which means each programmable item has be 
reset to its default value. It needs to be restarted to complete the whole process.

Note :

•In the program process, the motor will emit “Beep” tone when the LED is 

flashing.

• We use a long time flash and long “Beep---” tone to represent number “5” for 

identify the items of the big number.

• A long time flash (Motor sounds “B---”) = the No. 5

• A long time flash + a short time flash (Motor sounds “B---B”) = the No. 6

• A long time flash + 2 short times flash (Motor sounds “B---BB”) = the No. 7

• A long time flash + 3 short times flash (Motor sounds “B---BBB”) = the No. 8

• A long time flash + 4 short times flash (Motor sounds “B---BBBB”) = the No. 9 

• The Program Card is optional equipment which needs to 
be purchased separately. It has 3 digital LEDs to display the 
programmable items’ number and the options’ number. 
(Please refer to the user manual of the program card for 
detail info)

After power on, motor doesn’t work, and the 

cooling fan doesn’t work.

After power on, motor can’t work,but emits 

“beep-beep-, beep-beep-” alert tone. (Every 

“beep-beep-” has a time interval of 1 second )

After the ESC was powered on and finished LiPo 

cells detection (the GREEN LED flashed N times), 

and then the RED LED flashed rapidly.

The motor runs in the opposite direction 

when it is accelerated.

The motor suddenly stops running while in 

working state.

The LED program card kept display 3 short 

lines (- - -) after you connected it to your ESC.

The vehicle could run forward (and brake), 

but could not reverse.

The car ran forward/backward slowly when 

the throttle trigger was at the neutral 

position.

The connections between battery pack and 

ESC are not correct.

Input voltage is abnormal, too high or too low.

1. The ESC didn't detect any throttle signal.

2. The neutral throttle value stored on your ESC is 

different from the value stored on the transmitter.

1. The (ESC-to-motor) wiring order was incorrect.

2. Your chassis is different from popular chassis.

1. 

The throttle signal is lost.

2. 

The ESC has entered the Low Voltage

Protection Mode or Over-heat
The programming card/box was connected 

to the ESC via the throttle control cable (Rx 

cable).

1. The throttle neutral position on your transmitter 

was actually in the braking zone.

2. Set the “Running Mode” improperly.

3. The ESC was damaged.

1. The neutral position on the transmitter was 

not stable, so signals were not stable either.

2. The ESC calibration was not proper.

Check the power connections. 

Replace the connectors.

Check the voltage of the battery pack

1. Check if the throttle wire is reversely plugged in or in the 

wrong channel and if the transmitter is turned on.

2. Re-calibrate the throttle range after you release the throttle 

trigger to the neutral position.

Swap any two wire connections between the 

ESC and the motor.

1. Check the transmitter and the receiver,or the signal wire 

from the throttle channel of your receiver.

2. Red LED flashing means Low Voltage. Green LED flashing 

means Over-heat

It is wrong to use the Rx cable to connect programming 

card/box. The programming port of this ESC is also the fan 

port, so please connect the ESC and programming card/box by 

plugging the programming cable into the fan port.

1. Re-calibrate the throttle neutral position. No LED on the ESC 

will come on when the throttle trigger is at the neutral position. 

2. Set the “running mode” to “Forward/Reverse with Brake”.    

3. Contact the distributor for repair or other customer services.

1. Replace your transmitter

2. Re-calibrate the throttle range or fine tune 

the neutral position on the transmitter.

The Rx wire of the ESC (for connecting receiver) CANNOT be 

used to connect with the LED Program Card. Please only use 

the special port between the terminals ABC to connect with 

the Program Card.
