Connections

Please connect the wire correctly according to the instructions and drawing:

1. Motor Wiring:
   There is a difference between the connection of sensored brushless motor and sensorless brushless motor. Please according to the following wiring method:
   A. Connect sensored brushless motor:
   There is strict wiring order from the ESC to the motor, the three A/B/C ESC wires must connect to the three A/B/C motor wires correspondingly. Next, connect the ESC sensor port and the motor sensor port with the stock 6-pin sensor cable. If you don’t plug the sensor cable in, your ESC will still work in sensorless mode even if you’re using a sensored motor.
   Note: if the forward and backward are reversed after installing the motor, please modify “no. 11” parameters “Motor Rotation” to change the direction.
   B. Sensorless Motor Wiring:
   Users do not need to be worried in regards to the connectivity with the A/B/C(ESC and motor) as there is no polarity. You may find it necessary to swap two wires if the motor runs in reverse.

2. Receiver Wiring:
   Insert the throttle control flat cable of ESC into the throttle channel (i.e. THROTTLE channel) of the receiver. Since the red line in the flat cable outputs a 6-8.4v voltage to the receiver and steering servo. Please do not supply additional power to the receiver, otherwise, the electric adjustment may be damaged.

3. Battery Wiring:
   Please make sure that the (+) pole of the ESC is connected to the (+) of the battery, and the (-) pole is connected to the (-). If connect reversely, the ESC cannot startup. (Add the picture of connecting battery here.)

ESC Setup

Warning!

This is an extremely powerful system. For your safety and the safety of those around you, we strongly recommend removing the pinion gear attached to the motor before calibrating and setting this system. It is also advisable to keep the wheels in the air when you turn on the ESC.

Set the throttle range

When first use the ESC or the transmitter changes the “TRIM” tune, D/R, EPA, and other parameters, the throttle range is need to be reset. We strongly recommend opening the fail-safe function of the transmitter, setting the no signal protection of the throttle channel(“F/S” ) to close the output, or setting the protection value to the throttle neutral position. Thus the motor can stop running if the receiver cannot receive the signal of the transmitter. The calibrating steps of throttle are as follows:

1. Turn on the transmitter, ensure all parameters (D/R, EPA, 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. (If the transmitter is without LCD, turn the knob to the middle point).

2. Start by turning on the transmitter with the ESC turned off but connected to a battery. Holding the”SET” button then press the “ON/OFF” button, the RED LED on the ESC starts to flash (The motor beeps at the same time), and then release the “SET” button immediately.
   Note: Beeps from the motor may be low sometimes, and you can check the LED status instead.| |
   ---|---|---

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 RED LED dies out and the GREEN LED flashes 1 time and the motor beeps 1 time to accept the neutral
   • 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.
   Note:
   • The end position of forwarding: Pull the trigger to the maximum throttle position if it is the pistol-style transmitter. Push the throttle to the top if it is the board-style transmitter.
   • The end position of backward: Push the trigger to the maximum brake position if it is the pistol-style transmitter. Pull the throttle to the bottom if it is the board-style transmitter.

4. The motor can be started 3 seconds after the ESC/Radio calibration is complete.

Power on/off and Beep illustration

1. Illustration of power on/off Short press the ON/OFF key to turn on the ESC in the off state, and long-press the ON/OFF key to turn off the ESC.
2. Beep illustration when turning on the ESC: When turning on ESC under normal conditions (i.e. it is started without pressing the SET key), the motor will emit several Beeps to indicate the LiPo For example, “Beep, Beep, Beep” means 3S, “Beep, Beep, Beep, Beep” means 4S.

Programmable Items

1A. 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. Hobbywing has adopted the “DOUBLE-CLICK” method, that is your vehicle only brakes on the 1st time you push the throttle trigger forward (brake) (1st push). The motor stops when you quickly release the throttle trigger and then re-push the trigger quickly (2nd push), only then the vehicle will reverse. The reverse function will not work if your car does not come to a complete stop. The vehicle only reverses after the motor stops. This method is for preventing vehicles from being accidentally reversed.
Option 3: Forward and Reverse

This mode is often used by special vehicles. It adopts the “SINGLE-CLICK” method. The vehicle will reverse immediately when you push the throttle trigger forward (brake).

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. Lipo Cells:

We strongly recommend that you set LiPo cells manually not automatically. When set automatically, the ESC can judge as 2S or 4S. If the battery voltage is lower than 9.5V after power on the ESC, it will be judged as 25; if the battery voltage is between 9.5V 13.6V, it will be judged as 3S; if higher than 13.6V, it will be judged as 4S.

1D. Cutoff Voltage:

The ESC will monitor the battery voltage all the time, once the voltage is lower than the threshold value, the ESC will reduce the power to 50% instantly and cut off the power output in 40 seconds. When enters into voltage protection, the RED LED will single flash that repeats (⁕,⁕,⁕,⁕,⁕……………………… ) Please set the “Cutoff Voltage” to “Disabled” or customized protection threshold value 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. It is suggested to set it to “Disabled”(But the battery would be damaged due to being overcharged)

Option 2: Auto
The ESC calculates the corresponding cutoff voltage as per the number of LiPo cells it detects and the “3.3V/cell” rule. For example, if the ESC detects a 4S, the cutoff voltage protection threshold value is 3.5×4=14.0V.

Option 3: Customized
The customized cutoff threshold is a voltage for the whole battery pack (adjustable from 5.0V to 13.6V). Please calculate the value as per the number of LiPo cells you are using. For example, when you use a 4S and you want the cutoff voltage for each cell is 3.0V, you will need to set this item to 12V *(3.04)**

1E. ESC Thermal Protection:
The output from the ESC will be cut off with the value you have preset. The GREEN LED flashes (r, r,-,:r) when the ESC temperature reaches 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.

1F. Motor Thermal Protection:
The GREEN LED flashes ( *,,, ) when the motor temperature reaches 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 motors, the ESC may get this protection activated too early/late because of the different temperature sensors inside the motor. In this case, please disable this function and monitor the motor temperature manually.

1G. BEC Voltage:
BEC voltage can be adjusted between 6.0-8.4V. 6.0V is applicable to the common servo. If using a high-voltage servo, set it to a higher voltage according to the voltage marking of the servo. Warning: The setting BEC voltage should not be higher than the max. the voltage of the common servo, otherwise it will damage the servo or ESC.

1H. Sensor Mode:
Option 1: Full Sensored

If use the XERUN 4268/74-G2/G3 motor, it can be set to full sensor mode. The power system will work in the “censored” mode at all times. The efficiency and drivability of this mode are at their highest. And Boost‘ Turbo timing can be used and get erupting power.

Option 2: Sensored/Sensorless Hybrid
This is a universal driving mode of the current 1:8 power system. The ESC operates the motor in sensored mode during the low-speed start-up process, followed by switching to operating the motor in the “sensorless” mode when the RPM is increased.

1I: Motor Rotation:
With the motor shaft facing 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” is 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 designs. In that case, you only need to set the “Motor Rotation/Direction” to “CW.

1J: Phase-AC Swap:
If the NC wire of ESC connects to the NC wire of the motor with the crossed way (A wire of ESC connects to C wire of motor, C wire of ESC connects to A wire), set this item as Enable. Warning! When #A/#B/#C wire of ESC connect to #A/#B/#C wire of motor correspondingly, do not Set to Enable. Otherwise, it will damage the ESC and motor.

2A: Throttle Rate Control:
This item is used to control the throttle response. It can be adjustable from 1 to 30 (step: 1), the lower the throttle rate, the more the limit will be on the throttle response. A suitable rate can help the driver to control his vehicle properly during the starting-up process. Generally, you can set it to a high value to have a quick throttle response if you are proficient at throttle control.

2B: Throttle Curve:
The throttle curve parameter reconciles the position of the throttle trigger (in throttle zone) and the actual ESC throttle output. It is linear by default and we can change it to non-linear by adjusting the throttle curve. For example, if adjust 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:
As not all transmitters have the same stability at the “neutral position”, please adjust this parameter as per your preference. You can adjust to a bigger value when this happens.

2D: Initial Throttle Force:
It is also called minimum throttle force. You can set it according to wheel tire and traction. If the ground is slippery, please set a small throttle force.

2E:Coast:
The RPM of the motor will be lowered gradually when the throttle is reduced. The vehicle will not reduce speed abruptly when the throttle is reduced to return to the neutral position. The bigger the value, the more the “COAST” will be felt. For example, a COAST of 0 deactivates, and a COAST of 20% would be the maximum amount of COAST.

The advantages of COAST:

When a vehicle has a larger final drive ratio, the tendency of having a “drag” feeling 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 a better and smoother control feeling to racers. Some drivers will refer to this to the traditional brushed motors.

Note : The “Coast” will be void (even if you set it to any value besides 0) if the above “drag brake” is not “0%”.

2F: 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 (which ranges from 2K to 32K) at any 0-100% throttle input, Please choose the frequencies as per the actual test results of your vehicles.

2G: 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 the 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 makes it hard to control at the corners, so HOBBYWING creates this softening function to solve the issue.

2H: 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 Force:

3A: Drag Brake Force:
It is the braking power produced when releasing from full speed to a neutral position. This is to simulate the slight braking effect of a neutral brushed motor while coasting.

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 relationship between the throttle range in the braking zone and the brake force. The default setting is linear. You can change it to non-linear via an LCD program box and a PC (HOBBYWING USB LINK software needs to be installed on the PC.) for different braking effects.

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. If set this item to “Customized”, then the brake frequency can be adjusted to a variable value (which ranges from OK to 16K) at any 0-100% throttle input, please choose the frequencies as per the actual test results of your vehicles.

4A: Boost Timing:
It is effective within the whole throttle range; it directly affects the car’s speed on the straightaway and winding course. The ESC adjusts the timing dynamically as per the throttle amount in the operation. The Boost Timing is not constant but variable.

5A: Turbo Timing:
This item is adjustable from 0 degrees to 48 degrees, the corresponding turbo timing (you set) will initiate at full throttle. It’s usually activated on the 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 another 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 (deg/0.1sec):
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 seconds. Both the acceleration and heat is higher when the “Turbo increase rate” is of a larger value.

5D: Turbo Decrease Rate (deg/0.1sec):
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 the 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 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.

Note: Parameters 5A-5D only has a function when you set the “Drive Mode” to “Full Sensored”.

Preset modes

In order to make one firmware applicable to all different racing conditions, there are 5 groups of preset modes in the ESC. Users are able to change the settings of the modes provided and match suitable gear ratios. Plug-and-screw. Users can change the settings as per the control feel, track, and rename the setting mode. For example, the name can be changed from “1/8 Off-Road” to “NC2020-1900” to indicate the NC2020 uses 1900KV. This can be saved for future reference as well.

The explanation for LED status

1. During the Start-up Process
   • The RED LED keeps flashing rapidly indicating the ESC doesn’t detect any throttle signal or the neutral throttle value stored on your ESC may be different from the current value stored on the transmitter
   • The GREEN LED flashes “N” times indicating the number of LiPo cells you have connected to the ESC.

2. In Operation
   • The throttle trigger is at neutral: 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 to meet Blinky( Zero Timing) rules if the total value of Boost Timing and Turbo timing is O.
   • Forward: 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.
   • Brake: The RED LED dies out and the GREEN LED blinks when you brake your vehicle. The GREEN LED turns solid when pushing the throttle trigger to the full brake endpoint and setting the “Max. Brake Force” to 100%.
   • Backward: 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 “☆, ☆, ☆” indicating the low voltage cutoff protection is activated.
   • The GREEN LED flashes a short, single flash and repeats “☆, ☆, ☆” indicating the ESC thermal protection is activated.
   • The GREEN LED flashes a short, double flash and repeats “☆☆, ☆☆, ☆☆” indicating the motor thermal protection is activated.
   • The GREEN LEDs flash a short, single flash and repeat “☆☆☆, ☆☆☆, ☆☆☆” indicating that a load of ESC is heavy, the Over-Current protection is activated.
   • The GREEN LEDs flash a short, single flash and repeat “☆☆☆☆☆，☆☆☆☆☆，☆☆☆☆☆, indicating that the temperature of ESC and capacitor is too high, the thermal protection of capacitor is activated.
