1. Motor connection:
There is a difference between connecting a sensored brushless motor and a sensorless brushless motor:
A. When connecting to a sensored brushless motor:
The ESC to Motor connections must be connected correctly, the three A/B/C ESC wires must connect to the three A/B/C motor wires
correspondingly, otherwise, it may damage the ESC. Next, connect the sensor cable of the esc and motor according to the arrow mark on the sensor connector.
If you don’t plug the sensor cable in, your ESC will work in sensorless mode even if you’re using a sensored motor.
Note: If the motor direction is reversed, change the parameter on item 4 “Motor rotation direction” to achieve the correct setting.
B. When connecting to a sensorless brushless motor:
There are no wire sequencing requirements needed when using a sensorless brushless motor, you can swap two wires if the motor runs in opposite direction.
2. Recevier connection:
Connect the ESC throttle cable to the throttle channel on the receiver. Since the throttle cable of esc will have BEC voltage output to the receiver and servo, please do
not supply additional power to the receiver, otherwise the esc may be damaged. If additional power is required, disconnect the red wire on the throttle plug from the ESC.
3. Battery connection:
Make sure that the (+) pole of the ESC is connected to the (+) pole of the battery and (-) to the (-). If the connection is reversed, the ESC will be damaged and will not
be covered by the warranty.

06 ESC Setup
1 Set the Throttle Range – ESC Calibration Process
The calibration must be done on the first use of the ESC, or if a new radio or receiver is installed, otherwise the esc may not work correctly. We strongly recommend to open the fail safe function of the transmitter, set the no signal protection of throttle channel (“F/S”) to no pulses or set 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 calibration steps are below.
Hold the power button
Release the power button once the LED flashes.
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 without LCD, turn the knob to the middle point). This step can be skipped if the radio’s settings are default.
2. Start by turning on the transmitter with the ESC turned off but connected to a battery. Holding the”power” button for about 3 seconds, the RED LED in the switch starts to flash, release the button immediately (if the button is not released within 8 seconds, the Bluetooth name and password will be restored to the factory settings), and the motor will beep synchronously.
Note : Beeps from the motor may be low sometimes, and you can check the LED status instead.
With the throttle in the neutral position and press the power button.
The Green LED flashes once and motor emits “Beep” tone.
Move the throttle trigger to the full throttle and press the power button.
The Green LED flashes twice and motor emits “Beep-Beep” tone.
Move the throttle trigger to the full brake and press the power button.
The Green LED flashes three times and motor emits “BeepBeep-Beep” tone.
3. Set the neutral point, the full throttle endpoint and the full brake endpoint. · Leave transmitter at the neutral position, press the “power” 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 “power” 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 “power” 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 Power on/of f and beep instructions
Switch instructions: short press power button to power-on, long press on power button to shut down Power-on beep description: Under normal circumstances, the ESC will emit a few “beep” to indicate the number of lithium cells. A short “beep-” means the #1,
and a long “beep–” means the #5. For example: “beep–, beep-“means 6 cells, “beep–beep–, beep-beep-“means 12 cells. Finally,a long beep will sound to confirm the completion of the self-check. Note: Motor beeping at the same time, the ESC light flashes synchronously. For example: when the motor makes a long beep, the esc flashes for a long time, and when the motor makes a short beep, the esc flashes for a short time.

Note : Regarding the “Lipo Cells” item,MAX8 G2S supports 3-6S adjustable, MAX6 G2 supports 3-8S adjustable, and MAX5 HV Plus G2 supports 6-12S adjustable.
Regarding the “Max.Brake Force” item,the default value for MAX8 G2S is 50%,the default value for MAX6 G2 and MAX5 HV Plus G2 is 62.5%.
Regarding the “Turbo Timing” item,the MAX8 G2S can be set up to 32 degrees,the MAX6 G2 and MAX5 HV Plus G2 can be set up to 24 degrees.
Regarding the “ESC Thermal Protection” item,the MAX8 G2S and MAX6 G2 do not have this parameter setting.
1. Running Mode: Option 1: Forward with brake The vehicle can only move forward and has brake function. This is also commonly acceptable at races. Option 2: Forward/Reverse and Brake 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 When the throttle trigger is pushed to reverse position, the motor reverses. This mode is generally used in special vehicles.
2. Lipo Cells: Set the correct value according to the actual number of Lipo batteries used. The default is automatically calculated. Please note the “Auto” option will not recognize 5S and 7S, this is to avoid mis-calculation during actual use, for example, 6S Lipo without power may be incorrectly calculated as fully charged 5S Lipo. Therefore, this parameter value needs to be manually set when using 5S or 7S Lipo. Note: The”2S”option here is only reserved in the parameter table, due to the circuit characteristics and the suitable application of this esc, 2S Lipo is not supported.
3. Low Voltage Cut-Off: This function is mainly to prevent excessive discharge of lithium batteries causing damage. The ESC monitors the battery voltage at all times, and once the voltage falls below the set threshold, the power output is reduced and the power output is completely cut off after a few seconds. When the voltage protection is entered, the red LED flashes in the “-, -, -“. The three levels of low, medium, and high here correspond to 2.8V/Cell, 3.1V/Cell and 3.4V/Cell respectively. For NiMH batteries, it is recommended to set this parameter to “Disabled”.
4. Motor Rotation: Used to set the rotation direction of the motor. Due to differences in chassis frame structure, it is possible for the car to reverse when the throttle is applied to forward, in this case, you can solve it by adjusting this item.
5. BEC Voltage: BEC voltage support 6V/7.4V/8.4V. Generally, 6.0V is suitable for standard servos, while 7.4V/8.4V is suitable for high-voltage servos. Please set according to the servo specifications. WARNING! Do not set the BEC voltage above the maximum operating voltage of the servo and receiver, as this may damage the servo/reveiver or even the ESC.
6. 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 gear.
7. Max. Reverse Force: Refers to the reversing speed. Selecting different parameter values can produce different reversing speed. It is recommended to use a smaller reversing speed to avoid errors caused by reversing too quickly.
8. Punch: Punch can be used to control overall motor response, in relation to the throttle input. The higher the set value, the faster the acceleration. Lower punch settings are advised for softer starts, lower traction, or to help with motor hesitations or stuttering when throttle is applied rapidly.
9. Drag Brake Force:
Refers to the brake force generated by the motor when the throttle trigger returns to neutral position. Typically drag brake will be 0. Drag brake can add some
heat so use only as needed.
10. Initial Throttle Force:
It also called as minimum throttle force. Adjusting this setting to the available traction can help with acceleration. Set a lower value for low traction surfaces,
and higher values for higher traction surfaces.

11. Turbo Timing: It can be used to provide more top speed(at full throttle). The higher the value the higher the motor RPM will reach. PLEASE NOTE: Using the Turbo Timing will increase the running current, and temperatures of the motor and ESC.Use this with caution.
12. 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. If the delay is set the Turbo Timing will be delayed for the set amount, the throttle will need to be held at full throttle for the set delay before it initiates.
13. ESC Thermal Protection When it is set to”Enabled”, the power will be automatically reduced when the temperature of the esc reaches the preset value during operation, and the powerwill be turned off after about 40 seconds. When the ESC Thermal Protection is activated,the green light will flash: ” , , “. When this item is set to”Disabled”, the ESC Thermal Protection will not take effect,if the temperature of the esc continues to rise, it will be damaged due to overheating.There fore, please be cautious when setting this item. Due to being set to “Disabled” and causing damage to the esc, it will not be covered by the warranty.
4 Programming method

07 Explanation for LED status
1. The run status indication: 1) The throttle trigger is in the neutral point and the LED lights are off. 2) When advancing, the red light is constantly on, and when the throttle is at full throttle, the green light is on. 3) When reversing, the red light is constantly on; If the reversing force is set to 100%, the green light is also lit when the throttle is at the maximum of the reverse.
2. What the LED means when the relevant protection function is triggered: 1) The red light flashes (single flash, “, , “): enters the low voltage protection state. 2) The green light flashes (single flash, “, , “): enters the esc overheat protection state. 3) The green light flashes (double flash, “, , “): enters the motor overheat protection state. Note: Motor overheat protection is effective only when Hobbywing supporting motor (such as EZRUN 5690SD/4990SD G2
4278SD G2R) is used. When non Hobbywing supporting motor is used, there is no motor overheat protection function. 4) The green light flashes (three flashes, “, , “): enters the current protection state. 5) The green light flashes (five flashes, “, , “): enters the capacitor overheat protection state.
