Hobbywing recommends setting the "ESC Thermal Protection" to 105¥/ 221 (this refers to the internal temperature of the ESC). · The battery must be disconnected after use.There is a small draw even when the system is off,and will eventually fully drain the battery.This may cause damage to the ESC, and will NOT BE COVERED UNDER WARRANTY. 03 · Powerful hardware and software, designed for Drag Racing. · Factory standard 10AWG silicone wires and super large capacitor module,everything is ready. · RPM limit by throttle, Boost start rpm and end rpm are all finely adjustable,meeting the precise adjustment of the throttle by the driver. · Multiple protection functions: low-voltage cutoff protection, ESC and motor thermal protection, and fail safe. · The data recording function utilizes the OTA Bluetooth module to view various running data of the power system in the HW LINK App on mobile phones, making it easier for drivers to analyze the operation of the power system. · Firmware upgrade via Hobbywing LCD Pro program box or OTA Programmer (item sold separately). 04 Model Cont./Peak Current Motor Type Applications Recommended Motor LiPo Cells BEC Output Cooling Fan Size Weight Programming Port XERUN XR10 PRO DR 200A / 1200A Sensored Brushless Motors 1/10th Drag Racing 3652/3662(540/550) size motors KV9800 2S Lipo 5-7.4V Adjustable, Continuous Current of 5A Powered by the stable BEC voltage 37.7x37.2x33.2mm(w/Fan&Fan Shroud) 137g(w/ wires) Independent programming interface 05 Battery Electronic Speed Controller B C A Sensor port of motor Receiver Motor ATTENTION This is an extremely powerful brushless motor system. For your safety and the safety of those around you, we strongly recommend removing the pinion gear attached to the motor before performing calibration and programming functions with this system. It is also advisable to keep the wheels in the air when you turn on the ESC. Switch Sensor wire 1. Motor Connetion Sensored motor connection MUST connect A from the ESC to A on the motor, B to B, and C to C, with the sensor wire connected any variation of the motor to ESC connections may cause damage. Note: If the motor direction is reversed, change the parameter item "Motor Rotation" to achieve the correct setting. 2. Receiver Connetion The throttle control cable on the ESC has to be plugged into the throttle (TH) channel on the receiver. The throttle control cable has an output voltage of 5-7.4V to the receiver and steering servo, hence, no separate battery can be connected to the receiver. Otherwise, your ESC may be damaged.If additional power is required, disconnect the red wire on the throttle plug from the ESC. 3. Battery Connetion Proper polarity is essential. Please ensure positive (+) connects to positive (+), and negative (-) connects to negative (-) when plugging in the battery! If the connection is reversed,the ESC will be damaged and will not be covered by the warranty. 06 1 Set throttle range You must calibrate throttle range when you begin to use a new ESC, the transmitter has been replaced,or the Throttle TRIM have been adjusted, otherwise the ESC cannot work correctly. We strongly recommend users to use the "Fail Safe" function on the radio system and set (F/S) to "Output OFF" or "Neutral Position".The throttle calibration steps are below: Hold the SET button. Turn on the switch Release the SET button once the LED flashes. 1Turn on the transmitter, ensure all parameters (D/R, Curve, ATL) on the throttle channel are at default (100%). For transmitter without LCD, please turn the knob to the maximum, and the throttle "TRIM" to 0. Please also turn the corresponding knob to the neutral position. This step can be skipped if the radio's settings are default. 2. Turn off the ESC. Hold the SET button and turn on the ESC, the RED LED on the ESC starts to flash (the motor beeps at the same time), and then release the SET button. Note : Beeps from the motor may be low sometimes, and you can check the LED status instead. With the throttle trigger in the neutral position and press the SET button. Move the throttle trigger to the full throttle and press the SET button. Move the throttle trigger to the full brake and press the SET button. Press the SET button and the Green LED flashes once. Press the SET button and the Green LED flashes twice. Press the SET button and the Green LED flashes three times. 3. Set the neutral point, the full throttle endpoint and the full brake endpoint. · Leave transmitter at the neutral position, press the SET button, the GREEN LED flashes 1 time and the motor beeps 1 time to accept the neutral position. · Pull the throttle trigger to the full throttle position, press the SET button, the GREEN LED blinks 2 times and the motor beeps 2 times to accept the full throttle endpoint. · Push the throttle trigger to the full brake position, press the SET button, the GREEN LED blinks 3 times and the motor beeps 3 times to accept the full brake endpoint. 4. The motor can be started after the ESC/Radio calibration is complete. 2 Timing Brake Control Throttle Control General Setting Section Item 1A 1B 1C 1D 1E 1F 1G 2A 2B 2C 2D 2E 2F 2G 2H 2I 2J 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E 5A 5B 5C 5D Programmable Items Running Mode Max.

Running Mode Option 1: Forward with Brake Racing mode. It has only forward and brake functions. Option 2: Forward/ Reverse with Brake This option is known to be the "training" mode with "Forward/ Reverse with Brake" functions. The vehicle only brakes on the first time you push the throttle trigger to the reverse/brake position.If the motor stops when the throttle trigger return to the neutral position and then re-push the trigger to reverse position,the vehicle will reverse,if the motor does not completely stop,then your vehicle won't reverse but still brake,you need to return the throttle trigger to the neutral position and push it to reverse again.This method is for preventing vehicle from being accidentally reversed. Option 3: Forward and Reverse The motor will reverse immediately when the throttle trigger is pushed to reverse position.This mode is generally used in special vehicles. 1B. Max. Reverse Force The reverse force of the value will determine its speed. For the safety of your vehicle, we recommend using a low amount. 1C. Cutoff Voltage Sets the voltage at which the ESC lowers or removes power to the motor in order to either keep the battery at a safe minimum voltage (for LiPo batteries). The ESC monitors the battery voltage all the time, it will reduce the power to 50% (in 2 seconds) and cut off the output 40 seconds later when the voltage goes below the cutoff threshold. The RED LED will flash a short, single flash that repeats (, , ) to indicate the low-voltage cutoff protection is activated. Please set the "Cutoff Voltage" to "Disabled" or customize this item if you are using NiMH batteries. Option 1: Disabled The ESC does not cut the power off due to low voltage. We do not recommend using this option when you use any LiPo battery as you will irreversibly damage the product. You need to select this option when you are using a NiMH pack. Option 2: Auto The ESC calculates the corresponding cutoff voltage for the battery shall be 7.0V. Option 3: Customized The customized cutoff threshold is a voltage for the whole battery pack (adjustable from 3.0V to 7.4V). 1D. ESC Thermal Protection The output from the ESC will be cut off with the value you have preset. The GREEN LED flashes (, , ) when the ESC temperature reaches to the preset value. The output will not resume until the ESC temperature gets down. Warning! Please do not disable this function unless you're in a competition. Otherwise the high temperature may damage your ESC and even your motor. 1E. Motor Thermal Protection The GREEN LED flashes (, , ) when the motor temperature reaches to the preset value. The output will not resume until the motor temperature gets down. Warning! Please do not disable this function unless you're in a competition. Otherwise the high temperature may damage your motor and even your ESC. For non-Hobbywing motor, the ESC may activate the motor thermal protection too early or late due to the differences in the temperature sensors. In this case, please disable this function and monitor the motor temperature manually. 1F. BEC Voltage BEC voltage can be adjusted between 6.0-7.4V. 6.0V is applicable to common servo. If use high-voltage servo , set to higher voltage according to voltage marking of servo. 1G. Motor Rotation/Direction With the motor shaft faces you (the rear end of the motor is away from you), increase the throttle input, the motor (shaft) will rotate in the CCW/CW direction if the "Motor Rotation / Direction" set to "CCW/CW". Generally, the vehicle runs forward when the motor (shaft) rotates in the CCW direction. However, some vehicles only run forward when the motor rotates in the CW direction due to the different chassis design. In that case, you only need to set the "Motor Rotation/Direction" to "CW). 2A. Throttle Rate Control This item is used to control the throttle response. The higher the throttle rate,the more aggressive the throttle will be applied. A suitable rate can help driver to control the vehicle properly during the starting-up process. 2B. Throttle Curve The throttle curve parameter reconciles the position of the throttle trigger and the actual ESC throttle output. It is linear by default and we can change it to non-linear via adjusting the throttle curve. For example, if adjust it to +EXP, the throttle output at the early stage will be higher (than the output when the curve is linear); if it is adjusted to EXP, the throttle output at the early stage will be lower (than the output when the curve is linear). 2C. Neutral Range This parameter adjusts the range of the throttle neutral area to suit different transmitters and driver habits. If the neutral position of the transmitter is unstable,causing the car to move slowly forward or backward, or have difficulties calibrating the neutral range, the setting can be raised to correct the issue. 2D. Initial Throttle Force It also called as minimum throttle force. You can set it according to wheel tire and traction. If the ground is slippery, please set a small throttle force. Some motors have strong cogging effect with lower FDR ,if there is any cogging with very light throttle input,you can try to increase the initial throttle force. 2E. PWM Drive Frequency The acceleration will be more aggressive at the initial stage when the drive frequency is low; a higher drive frequency is smoother but this will create more heat to the ESC.If set this item to "Customized", then the PWM frequency can be adjusted to a variable value at any 0-100% throttle input, Please choose the frequencies as per the actual test results of your vehicles. 2F. Softening Value It allows users to fine-tune the bottom end, change the driving feel, and maximize the driving efficiency at different track conditions. The higher the "Softening Value ", the milder the bottom end. In Modified class, drivers often feel the power of the bottom end is too aggressive. Little throttle input usually brings too much power to the car and make it hard to control at the corners, this is HOBBYWING's solution to help bottom end traction. Note: You can increase the motor mechanical timing accordingly after you set the softening value. Every time you increase the softening value by 5 degrees, you can increase the mechanical timing by 1 degree. For example, if you set the softening value to 20 degrees, then you can increase the mechanical timing by 4 degrees. Please note that you will never increase the mechanical timing by over 5 degrees. 2G. Softening Range It's the range to which "Softening Value" starts and ends. For example, 0% to 30% will be generated when the user pre-programs the "Softening Range" at a value of 30%. 2H. RPM Limit By Throttle This parameter refers to the maximum motor rpm allowed within the throttle range, associated with item 2I (RPM Limit Range). 2I. RPM Limit Range Refers to the throttle range corresponding to the limited motor rpm. For example,if the item 2H (RPM Limit By Throttle) is set to 20000,and this item is set to 30%,it means that the maximum motor rpm limited within the 30% throttle range is 20000. 2J. Max RPM Limit Refers to the maximum motor rpm limit with the whole throttle range. 3A. Drag Brake It is the braking power produced when releasing from the throttle to neutral position. This is to simulate the slight braking effect of a neutral brushed motor while coasting. It's not recommended for buggy and monster truck. (Attention! Drag brake will consume more power and heat will be increased, apply it cautiously.) 3B. Max. Brake Force This ESC provides proportional braking function; the braking effect is decided by the position of the throttle trigger. It sets the percentage of available braking power when full brake is applied. Large amount will shorten the braking time but it may damage your pinion and spur. 3C. Brake Rate Control It's adjustable from 1 to 20 (step: 1). The larger the setting value, the greater the brake rate, that is, the faster the braking. A suitable rate can aid the driver to brake his vehicle correctly. Generally, you can set it to a high value to have a quick brake response. 3D. Brake Frequency The brake force will be larger if the frequency is low; you will get a smoother brake force when the value is higher.If set this item to "Customized", then the brake frequency can be adjusted to a variable value at any 0-100% throttle input. Please choose the frequencies as per the actual test results of your vehicles. 3E. Brake Control Option 1: Linear Hobbywing has recommended using this mode under all circumstances. The braking effect is a bit weaker in this mode than in Traditional brake mode, but it's easy to control and brings great control feel. Option 2: Traditional This brake mode is the same as to other standard ESCs, the brake force is stronger. Option 3: Hybrid The ESC switches the brake mode between Linear and Traditional as per the vehicle speed to prevent the slide (between tires and track) from affecting the braking effect. Note: Please select the right mode for your vehicle as per the track condition, motor performance, and etc. 4A. Boost Timing It is effective within the whole throttle range; it directly affects the car speed on straightaway and turns.The actual boost timing during the operation is adjusted based on the parameter item 4B. The Boost Timing is not constant but variable. 4B. Boost Timing Activation Option 1: RPM In RPM mode, the ESC adjusts the Boost Timing dynamically as per the motor speed (RPM). The actual Boost Timing is 0 when the RPM is lower than the Boost Start RPM. The Boost Timing changes as per the RPM when the RPM change is between the Boost Start RPM and the Boost End RPM. For example, if the Boost Timing is set to 5 degrees and the Boost Start RPM is 10000, the Boost End RPM is 15000. The Boost Timing corresponds to different RPM is shown below. When the RPM is higher than the Boost End RPM, the actual Boost Timing is the value you had previously set. RPM (Motor Speed) Actual Boost Timing <10000 0 Degree 10001-11000 1 Degree 11001-12000 2 Degrees 12001-13000 3 Degrees 13001-14000 4 Degrees 14001-15000 5 Degrees >15000 5 Degrees Option 2: Auto In Auto mode, the ESC adjusts the Boost Timing dynamically as per the throttle amount. Only at full throttle, the actual Boost Timing is the value you had previously set. Option 3: Timing Rate In this mode, the boost timing is turned on according to the value set by the parameter item 4E(Boost Increase Rate). 4C. Boost Start RPM This item defines the RPM at which Boost Timing is activated. For example, when the Boost Start RPM is set to 5000, the ESC will activate the corresponding Boost Timing when the RPM goes above 5000. The specific value is determined by the Boost Timing and the Boost End RPM you had previously set. 4D. Boost End RPM This item defines the RPM at which Boost Timing (you specifically set) is applied. For example, when Boost Timing is set to 10 degrees and the Boost End RPM to 15000, the ESC will activate the Boost Timing of 10 degrees when the RPM goes above 15000. The ESC will adjust the Boost Timing accordingly as per the actual RPM when the RPM goes below 15000. 4E. Boost Increase Rate Used to set the speed of the Boost response.Release a certain degree every 0.1 seconds until fully released. For example, if the parameter is set to 4 °/0.1s and the Boost timing is set to 40 degrees, the Boost timing will be released at a speed of 4 degrees/0.1s, and after 1 second, all 40 degrees will be released. 5A. Turbo Timing This item is adjustable from 0 degree to 64 degrees, the corresponding turbo timing (you set) will initiate at full throttle. It's usually activated on long straightaway and makes the motor unleash its maximum potential. 5B. Turbo Delay When "TURBO DELAY" is set to "INSTANT", the Turbo Timing will be activated right after the throttle trigger is moved to the full throttle position. When other value(s) is applied, you will need to hold the throttle trigger at the full throttle position (as you set) till the Turbo Timing initiates. 5C. Turbo Increase Rate This item is used to define the "speed" at which Turbo Timing is released when the trigger condition is met. For example, "3 degs/0.1sec" refers to the Turbo Timing of 6 degrees that will be released in 0.1 second. Both the acceleration and heat is higher when the "Turbo increase rate" is of a larger value. 5D. Turbo Decrease Rate After the Turbo Timing is activated and the trigger condition turns to not be met (i.e. vehicle slows down at the end of the straightaway and gets into a corner, full throttle turns to partial throttle, the trigger condition for Turbo Timing turns to be not met), if you disable all the Turbo Timing in a moment, an obvious slow-down like braking will be felt and cause the control of vehicle to become bad. If the ESC can disable the Turbo Timing at some "speed", the slow-down will be linear and the control will be improved. WarningBoost Timing & Turbo Timing can effectively improve the motor efficiency; they are usually used in competitions. Please take some time to read this manual and then set these two items carefully, monitor the ESC & motor temperatures when you have a trial run and then adjust the Timing and FDR accordingly as aggressive Timings and FDR may cause your ESC or motor to be burnt. 3 In order to make one firmware applicable to all different racing conditions, there are ten "easy-to-select" preset modes. Users are able to change the settings of the modes provided (and rename those modes) as per the control feel, track, and etc. For example, the profile name can be changed to "TITI2024_MOD_4.5" to indicate the race was ran with a 4.5T motor at 2024 TITC. This can be saved for future reference as well. 4 1.
