chassis is different from popular chassis.
1. Check all devices and try to find out all possible causes, and check the
transmitter’s battery voltage.
2. The RED LED keeps flashing indicating the LVC protection is activated,
please replace your pack.
3. The GREEN LED keeps flashing indicating the thermal protection is
activated, please let your ESC cool down before using it again.
1. Recalibrate 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 “Fwd/Rev with Brk “.
3. Contact the distributor for repair or other customer service.
1. Check all soldering points, please re-solder if necessary.
2. Contact the distributor for repair or other customer service.
1. Change another pack with great discharging capability.

3. Set the punch/start mode to a low level.
1. Check if the sensor cable is loose or poor contact issue exists.
2. Hall sensor inside the motor is damaged.
The ESC was unable to start the motor, but the
RED LED on the ESC turned on solid.
The vehicle ran backward when you pulled the
throttle trigger towards you.
The ESC was unable to start the status LED, the
motor, and the cooling fan after it was powered on.
The motor stuttered but couldn’t start.
The vehicle could run forward (and brake),
but could not reverse.
The motor got stuck or stopped when increasing
the throttle during the starting-up process.
The RED & GREEN LEDS on the ESC flashed rapidly
at the same time when the throttle trigger was at
the neutral position.
The motor suddenly stopped or significantly
reduced the output in operation.
1. Poor discharging capability of the pack.
2. The RPM of the motor was too high, or the FDR
was too low.
3. Set the "Punch/Start Mode" to a high level.
(When pairing with a sensored motor) the ESC
automatically switched to sensorless mode
when it detected incorrect signal from Hall sensor.
1. Check if the wiring order is A-A, B-B, and C-C.
2. Contact the distributor for repair or other customer service.

Guidance
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.
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.
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, “6 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.
Warning
！
Boost 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.
1) Program your ESC with a multifunction LCD program box
You can program this XR10 STOCK SPEC ESC via a multifunction LCD program box or via a multifunction LCD program box & a PC (HOBBYWING USB LINK software needs to be
installed on the PC). Before programming, you need to connect your ESC and the LCD program box via a cable with two JR male connectors and turn on the ESC; the boot
screen will show up on the LCD. Press any button on the program box to initiate the communication between your ESC and the program box. Seconds later, “CONNECTING
ESC” will be displayed, and indicates the following parameters. You can adjust the setting via “ITEM” & “VALUE” buttons, and press the “OK” button to save new settings to
your ESC.
2) Program your ESC with a WiFi Module
The XR10 STOCK SPEC ESC can also be programmed via a WiFi module along with smart phone devices (HOBBWYING WiFi LINK software
needs to be installed on the smart phone). Before programming, users will need to plug the programming cable on the WiFi module into the
programming port on ESC and switch on the ESC. For detailed information about ESC programming via WiFi module, please refer to the
user manual of Hobbywing’s WiFi Express.
Attention!
This ESC has a separate programming port. Please don’t use the throttle control cable (also called Rx cable) on the ESC to
connect the program box; otherwise the program box won’t function.
3) Data Checking
The ESC is able to record the maximum ESC temperature, maximum motor temperature, minimum battery voltage and maximum motor speed in operation. It automatically saves
the recorded data to the designated area when you turn off the ESC after a run. You can check those data via a multifunction LCD program box whenever necessary.
Users need to switch on the ESC after connection between the program box and the ESC has been established. Press the “R/P” button on any “item” page followed by pressing
the “R/P” button again multiple times. The following 5 item pages will be displayed circularly: Mode
→
ESC Temperature
→
Motor Temperature
→
Min Voltage
→
Max RPM.
Attention!
• Press the “VALUE” button on any data-recording page can get you into the next preset mode. Please note that improper operation will get you into other preset mode(s).
• Press the “ITEM” button on any data-recording page can get you to the parameter setting page of the current preset mode; press the “R/P” button if you want to return to
the data-recording page

Explanation for LED Status
1. During the Start-up Process
• The RED LED turns on solid indicating the ESC doesn’t detect any throttle signal or the throttle trigger is at the neutral position.
• The GREEN LED flashes rapidly indicating the neutral throttle value stored on your ESC may be different from the current value stored on the transmitter. When this happens,
re-calibrate the throttle range.
2. In Operation
• The RED LED turns on solid and the GREEN LED dies out when the throttle trigger is in the throttle neutral zone. The RED LED will blink slowly (to confirm with ROAR’s Sportman
(or Zero Timing) rules) if the total value of Boost Timing and Turbo timing is 0.
• The RED LED dies out and the GREEN LED blinks when your vehicle runs forward. The GREEN LED turns solid when pulling the throttle trigger to the full (100%) throttle endpoint.
• The RED LED dies out and the GREEN LED blinks when you brake our vehicle. The GREEN LED turns solid when pushing the throttle trigger to the full brake endpoint and setting the
“maximum brake force” to 100%.
• The RED LED dies out, the GREEN LED blinks when you reverse your vehicle. The GREEN LED turns solid when pushing the throttle trigger to the full brake endpoint and setting the
“reverse force” to 100%.
3. When Some Protection is Activated
• The RED LED flashes a short, single flash and repeats “

Note:
this section is applicable to the situation when the motor limit is regulated and the ESC timing is not regulated.
1) You can get a higher top end speed via the following methods:
• Decrease the FDR (by using a bigger pinion within the reasonable range)
• Increase the Timing. If you only want to increase the top end speed on straightaway, you can increase the Turbo timing. If you want to increase the speed at different sections of
the entire track, you can increase the Boost timing.
• Change another battery with higher discharge capability.
2) You can get a higher acceleration via the following methods:
• Increase the FDR (by using a smaller pinion within the reasonable range).
• Increase the throttle acceleration.
• Increase the Boost Timing.
• Decrease the Boost Start RPM & the Boost End RPM.
• Decrease the Turbo Delay.
• Increase the Turbo Increase Rate.
3) You can get a lower motor temperature and a longer run time via the following methods:
• Increase the FDR (by using a smaller pinion within the reasonable range)
• Decrease the Timing
• Increase the Boost Start RPM & the Boost End RPM.
• Increase the Turbo Delay
• Decrease the Turbo Decrease Rate.
Note:
Please adjust the FDR and other parameters slightly (feel and test the ESC and motor temperatures after every adjustment.), keep trying different settings until you get the
“satisfactory” speed and the acceptable motor/ESC temperature. You can also save the “setting” for future reference or use.

What is COAST?
When a vehicle has a larger final drive ratio, the tendency of having a “drag” feel is higher. The “COAST” technology is to allow the car to roll (coast) even when the final drive ratio
is high. The Coast function brings better and smoother control feeling to racers. Some drivers will refer to this to the traditional brushed motors.
Note 5:
The “Coast” will be void (even if you set it to any value besides 0) if the above “drag brake” is not “0%”.
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.
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 some 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, so HOBBYWING creates this softening function to solve the issue.
Note 6
: 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%.
3A. Drag Brake
It is the braking power produced when releasing from full speed 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. Initial Brake Force
It is also known as “minimum brake force”. It is the force when pushing throttle trigger from neutral zone to the initial brake position. To get a smoother braking effect, the default is
equal to the drag brake.
3D. Brake Rate Control
It’s adjustable from 1 to 20 (step: 1), the lower the brake rate, the more limit on the brake response. 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.
3E. Brake Curve
This item is used for regulating the relation between the throttle range in brake zone and the brake force. The default setting is linear. You can change it to non-linear via a LCD
program box and a PC (HOBBYWING USB LINK software needs to be installed on the PC.) for different braking effect.
3F. 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.
3G. 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 the XERUN series of 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 7:
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 winding course. The ESC adjusts the timing dynamically as per the RPM
(when “Boost Timing Activation” set to “RPM”) or throttle amount (when “Boost Timing Activation” set to “Auto”) in the operation. 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.
