1. 3 Low Voltage Cut Off The function is mainly to prevent the lithium battery pack from over discharging When using lithium battery pack please set the suitable value for low voltage protection as your like WARNING Never use the default value Non protection for lithium battery The ESC monitors the battery s voltage at any time if the voltage is lower than the threshold the output power will be reduced to 50 in 2 seconds Please drive and stop the car at the side of the racing track as soon as possible the ESC will completely cut off the output power in 10 seconds 3 4 Start Mode Also called Punch Select from Level1 Soft to Level 9 Very aggressive start mode as your like Please note that if you choose Level 7 to Level 9 you d better use good quality battery pack with powerful discharge ability otherwise these modes cannot get the bursting 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 betier battery or increase the gear rate 3 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 3 6 Maximum Reverse Force Sets h2. 9 ay yo yayas BulwwweBbod ysu Hold SET key for 3 seconds Press SET key to choose the value the flash times of RED LED means the serial number of the value 1 time means the 1st value 2 times means the 2nd value Green LED flashes Enter the N item for N times Release SET key Press SET key 2 Note 3 In the program process the motor will emit Beep tone at the same time when the LED is flashing 4 1 Ifthe N is bigger than the number 5 we use a long time flash and long Beep tone to represent 5 5 so itis easy to identify the items of the big number 6 For example if the LED flashes as the following 7 Along time flash a short time flash Motor sounds Beep Beep the No 6 item 8 Along time flash 2 short time flash Motor sounds Beep BeepBeep the No 7 item 9 A long time flash 3 short time flash Motor sounds Beep BeepBeepBeep the No 8 item 10 2 2 11 And so on Programmable aa T Basic Items Forward Forward Reverse Rock with Brake with Brake Crawler Running Mode 2 Drag Brake mo a aiii 3 Low Voltage Non Protection 2 6V 2 8V 3 0V 32 4 AV Cut Off Threshold Cell Cell Cell Cell iCall 4 n ae L9 Advanced Items 5 Maximum Brake Force 6 Maximum Force Force 3 Neutral Range 9 Normal Sd 2 T
3. Setting Throttle Range Calibration In order to make the ESC fit the throttle range you must calibrate it for the following cases otherwise the ESC cannot work properly 1 Begin to use a new ESC 2 Begin to use a new transmitter 3 Change the settings of neutral position of the throttle stick ATV or EPA parameters etc There are 3 points need to be set they are the top point of forward backward and the neutral point The following pictures show how to set the throttle range with a FutabaTM transmitter A Switch off the ESC turn on the transmitter set the direction of throttle channel to REV set the EPA ATV value of throttle channel to 100 and disable the ABS brake function of your transmitter Note2 B Hold the SET key and then switch on the ESC when the red LED begins to flash release the key immediately Hold the Set key Please refer to the picture on the right side SK f C Set the THREE points according to the steps shown in the picture on Move the throttle stick fo the Move the irole stick to the Move the trottle stick to the the right side neuiral position and position of forward end position of backward 1 Neutral point ie 4 LAB C 2 End point of forward HL A I ah A AN w l f i yi i Hi A il i a AN i direction l l Y d i It f a 3 End point of backward M oe Fa direction w E D When the process of Press SET k
