1. Parameters from 1 to 100 1 incremental A lower Throttle Punch percentage will have a slower throttle response and feel softer initially A higher Throttle Punch per centage will have a faster throttle response Throttle Curve Parameters are EXP1 to EXP5 Linear EXP1 to EXP5 A lower Throttle Curve EXP will have a softer throttle feel at the beginning of the throttle power band and get more aggressive as it is fully engaged A linear Throttle Curve will be uniform throughout the whole throttle range A higher Throttle Curve EXP has strong throttle initially and then becomes softer Dead Band Parameters are Off Narrow Middle Wide This is the amount of play when the throttle is engaged Off makes the throttle engage more instantaneously while Wide would have a lag Throttle Punch EXP5 EXP1 Linear EXP1 EXP5 Throttle Position PROGRAMMING OPTION DRAG BRAKE Neutral Brake Parameters from 0 Disabled to 100 1 Incremental This is how much brake is applied at neutral throttle Neutral brake is still functional regardless if Dynamic Brake is enabled or not DYNAMIC DRAG BRAKE Dynamic Drag Brake is an advanced function under the option of Drag Brake It offers another step of drag brake at higher RPM of your choice It is with 3 parameters Trigger RPM sets the motor RPM where you wish the Dynamic Drag Brake to trigger Max Brake Strength sets the brake strength level when Dynamic Drag Brake kicks
2. PROGRAMMING OPTION BRAKE Brake Strength Parameters from 0 Disabled to 100 1 incremental A lower Brake Strength percentage will have less push brakes while a higher percentage will have stronger push brakes Brake PWM Frequency Parameters are 2000Hz 2500Hz 3200Hz 4000Hz 8000Hz 12000Hz 16000Hz PWM stands for Pulse Width Modulation and is rated in Hertz meaning cycles per second A lower frequency will have a more aggressive braking feel A higher frequency results in smoother braking is more precise and increases the ESC temperature Brake Curve Parameters are EXP1i to EXP5 Linear EXP1 to EXP5 A negative EXP Brake Curve will have a softer brake feel at the beginning of the brakes being engaged and get more aggressive as the brake are fully engaged A linear Brake Curve will be uniform throughout the whole brake range A positive EXP Brake Curve has strong brakes initially and then becomes softer Brake Strength EXP5 EXP1 Linear EXP1 EXP5 Motor RPM PROGRAMMING OPTION THROTTLE Throttle PWM Frequency Parameters are 2000Hz 2500Hz 3200Hz 4000Hz 8000Hz 12000Hz 16000Hz PWM stands for Pulse Width Modulation and is rated in Hertz meaning cycles per se cond A lower frequency will have a more aggressive throttle feel and have less motor RPM A higher frequency results in smoother throttle is more precise produces more motor RPM and increases the ESC temperature Throttle Punch
3. ated by blinking F and R LEDs with solid N LED PROGRAMMING OPTION MOTOR POWER VIPER VTX series ESC offers advanced timing system for extreme racing competitions The MOTOR POWER has 2 sections with 5 parameters It allows you to set up and enhance acceleration and top speed performance Tips Always start testing the MOTOR TIMING with minimum advanced timing Most sensored brushless motors have 30 degrees physical advanced timing with adjustable end bell for more or less timing The total advanced timing motor ESC should not be over 60 degrees for optimized performance and efficiency Warning MOTOR TIMING option generates a lot of power and will easily overheat and moreover to damage both ESC and motor VIPER R C SOLUTIONS will not be responsible for any equipment damage caused by MOTOR POWER settings ACCELERATION BOOST Start RPM Parameters from 500 to 30000 RPM 500 RPM incremental This sets the start RPM that acceleration timing engages This parameter should be based on the motor KV and the track condition To calculate Start RPM Start RPM Motor KV x 6 4 x 0 3 For example if the motor KV is 2000 it will be 2000x6 4x0 3 3840 Then you set the START RPM 3500 to 4000 Set Up Tips Lower start RPM does not mean to have more power at lower end The motor needs to have enough RPM before the acceleration timing could kick in efficiently Try to start the parameter at higher side and monitor the motor temper
4. ature before making next adjustment Finish RPM Parameters from 500 to 50000 RPM 500 RPM incremental This sets the start RPM that acceleration timing finishes To calculate the Finish RPM FINISH RPM Motor KV x 6 4 For example if the motor KV is 2000 it will be 2000x6 4 12800 Then you set the finish RPM 12000 to 13000 Max Advanced Timing Parameters from 0 to 40 degrees 1 degree incremental This sets the maxi mum advanced timing at the time the motor reaches the set Finish RPM TOP SPEED TIMING Slew Rate Parameters from 1 to 50 degrees 1000RPM 1 degree incremental This sets how fast the ESC reaches the maximum advanced top speed timing The larger number will have more aggressive top speed acceleration while the smaller number will have smoother feel Max Advanced Timing Parameters from 0 to 40 degrees This sets the maximum advanced timing at the time the motor reaches top speed range PROGRAMING OPTION MISC CONTROL Run Mode Parameters are Practice Race Stock Race Modified Practice allows all settings to be adjusted on the ESC Also it allows reverse Race Stock locks out reverse and does not allow any Motor Timing to be adjusted Race Modified locks out reverse while maintaining Motor Timing adjustability SBEC Voltage Parameters from 5 0V to 7 0V 0 1V incremental A higher voltage will make servos react faster at the expense of a shorter life span However do not set SBEC Voltage above the s
5. ervo manufacturer s recommended voltage Forward Power Parameters from 50 to 100 1 incremental This setting allows you to limit the forward power Reverse Power Parameters from 25 to 100 1 incremental This setting allows you to limit the reverse power Auto Power Off Parameters from 1 to 10 minutes 1 minute incremental This allows the user to set the ESC to power off if it remains in neutral for the amount of minutes set
6. in Dynamic Curve sets the brake curve from Max Brake Strength to Neutral Brake point Max Brake Strength Parameters from 0 Disabled to 100 1 incremental This is how much brake is applied at the top of the Dynamic Brake Curve after the Activate RPM is reached Dynamic Curve Parameters are EXP1 to EXP5 Linear EXP1 to 1EXP5 This is engaged after the Neutral Brake percentage is reached A negative EXP Dynamic Brake Curve will have a softer brake feel at the beginning of the brakes being engaged and get more aggressive as they are fully engaged A linear Dynamic Brake Curve will be uniform throughout the whole brake range A positive EXP Dynamic Brake Curve has strong brakes initially and then becomes softer Trigger RPM Parameters from 500RPM to 60000RPM SOORPM incremental The motor RPM that engages the Max Brake Strength Brake Max Brake Strength EXP5 EXP1 Linear EXP1 EXP5 Neutral Brake Trigger RPM PROGRAMING OPTION PROTECTION Battery Cut Off Parameters from 4 5V to 13 5V 0 1V Incremental Allows user to set the cut off for the appropriate voltage per type of battery used Motor Temperature Cut Off Parameters from 160 Degrees to 270 Degrees 10 degrees incremental Motor temperature cut activation is indicated by blinking F and R LEDs ESC Temperature Cut Off Parameters from 160 Degrees to 270 Degrees 10 degrees incremental ESC temperature cut activation is indic
