STEP 1: Throttle Mode | Confirming Uni-directional or Bi-directional Operation
The DEFIANT ESC features our innovative Multi-Directional Technology, enabling it to function as either a uni-directional or bi-directional ESC. By default, the ESC ships in uni-directional mode (motor spins in one direction only). If this mode suits your needs, you can skip this step and proceed to step 2. However, if you require the ESC to operate in bi-directional mode (motor spins in both directions), simply follow the instructions below to change the setting.
*If needed, see section 07 programmable settings under setting "7. Throttle Mode" for more information about the difference between uni- and bi-directional modes.
*If needed, see section 07 programmable settings under setting "7. Throttle Mode" for more information about the difference between uni- and bi-directional modes.

Diagram Instructions
*The diagram above is for general use. Your setup may be different, e.g., if your maximum throttle position is reversed. Refer to the written instructions above the diagram for more detail.
Written Instruction
Changing the Throttle Mode:
*Note: Ensure a motor is connected to hear the beeps, as the ESC generates sound through the motor.
- Set the transmitter's throttle to the maximum position.
- Connect the ESC to power.
- The ESC will begin by emitting a single beep via the motor, followed by a brief pause. It will then incrementally produce more beeps, with a short pause between each set of beeps.
- Wait for the ESC to emit three beeps.
- Before the ESC emits four beeps, move the throttle to the minimum position.
- The ESC will repeatedly alternate between emitting one and two beeps, with a brief pause in between. To activate the desired throttle type, follow the instructions below:
- Uni-directional Mode: Wait for the ESC to emit ONE beep, then proceed to the next step.
- Bi-directional Mode: Wait for the ESC to emit TWO beeps, then proceed to the next step.
- Set the throttle to the minimum position.
- After a few seconds, the motor will produce four rapid alternating beeps to confirm that the throttle type has been saved.
- Power off the ESC.
- The Throttle Mode has been saved. Next continue to Step 2: Throttle Calibration Procedure to help ensure the smoothest throttle operation.
*Note: Ensure a motor is connected to hear the beeps, as the ESC generates sound through the motor.
STEP 2: Throttle Calibration Procedure
The ESC is designed for plug-and-play operation, and typically, there is no need to modify the settings (programming). However, we recommend performing a throttle range calibration when using the ESC for the first time or when changing receivers. This calibration establishes the minimum and maximum throttle points, ensuring smooth and precise throttle control.
If you wish to modify the ESC's settings, refer section 06 How to Change The ESC's Settings (Programming) for more detailed instructions.

Normal Start-up Procedure:
*Note: Ensure a motor is connected to hear the beeps, as the ESC generates sound through the motor.
- Set the throttle to the zero-throttle position (refer to Section 04: First Time Use | Throttle Mode and Calibration for changing the ESC throttle mode between uni-directional and bi-directional):
- Uni-directional Mode: Zero-throttle position is the minimum throttle position, typically achieved by moving the transmitter stick all the way down.
- Bi-directional Mode: Zero-throttle position is the center of the throttle range. Most transmitters set up for bi-directional use have a spring that moves the throttle to the center.
- Connect the ESC to power. The ESC may exhibit the following responses, depending on the throttle position:
- If the throttle is partially on, the ESC enters Safe Start Protection mode, making rapid short beeps until the throttle is moved to the zero-throttle position. See section 08 ESC Features and Protections for more information.
- If the throttle is close to the maximum position, the ESC enters Programming mode. The ESC will emit a series of incrementing beeps via the motor, with brief pauses between each set of beeps. Each set of beeps corresponds to a different setting to program. In this case, power off the ESC and restart with the throttle in the zero-throttle position. For more information, see section 06 How to Change the ESC's Settings (Programming).
- The ESC will emit a series of short beeps:
- The first set of beeps indicates the number of battery cells detected by the ESC (e.g., 3 beeps for a 3-cell battery). If necessary, change the ESC's battery-type setting (default is LiPo). See section 06 How to Change the ESC's Settings (Programming) for more information.
- The second set of beeps indicates the brake setting:
- One beep for the brake on.
- Two beeps for the brake off.
- The ESC is now ready for use.
*Note: Ensure a motor is connected to hear the beeps, as the ESC generates sound through the motor.
06 How to change the ESC Settings (Programming) |

*See the table of programmable settings above
written instructions
The ESC will emit incrementing beeps via the motor, pausing briefly between each set. Each set of beeps corresponds to one of the 12 programmable settings. If no settings are selected by the end, the ESC cycles through them again automatically. To select a setting, listen for the number of beeps and move the throttle to the minimum position BEFORE the next set of beeps begins.
Now that the desired setting is selected, we will choose the appropriate option for that setting. The ESC will emit incrementing beeps, pausing briefly between each set, corresponding to the available options. If no option is selected by the end, the ESC will cycle through them again automatically. To select an option, listen for the number of beeps and move the throttle to the maximum position BEFORE the next set of beeps begins.
Listen for four confirmation beeps in a burst. Afterward, disconnect the ESC, and it is ready for use.

3. Throttle Mode
Throttle Mode: Uni-directional, Bi-Directional
1. Uni-directional: The motor spins in one direction only, suitable for airplanes and scenarios requiring a single spinning direction. Transmitters for uni-directional operation typically lack a return spring on the throttle lever or have one that moves to the minimum throttle position.
2. Bi-directional: The motor can spin in both forward and reverse directions, ideal for cars, boats, and other applications. Transmitters for bi-directional operation generally have a return spring that centers the throttle lever, with positions above the center spinning the motor in one direction and those below in the reverse direction.
Also see section 04 First-time Use | Throttle Mode and Calibration under "STEP 1: Throttle Mode | Confirming Uni-directional or Bi-directional Operation" for more info.

08 ESC Safety Features and Protections |
|
Start up Protection
The ESC will stop the motor if the motor fails to spin within two seconds after applying the throttle. Possible situations that would cause this fault are: The motor or propeller cannot freely rotate, a connection between the motor and ESC, or an electrical short in the motor.
Safe Start Protection
If the throttle is applied before the ESC is powered on, the ESC will not power the motor and will beep rapidly until the throttle is put in the minimum throttle position. Then the ESC will go through its start up procedure as usual. This is to prevent the motor from unexpectedly starting up when powering on the ESC
Overheat Protection
If the ESC gets hotter than 212 °F (100 ℃), the ESC will limit the output power to 40% to prevent the ESC from becoming damaged without shutting off all power output during operation. Once the ESC's temperature reaches operating temperature, the ESC will work as usual.
Signal Protection
If the receiver losses signal for more than two continuous seconds, the ESC will reduce power. If the lost signal continues for more than four seconds, the ESC will gradually shut off power to the motor, preventing a runaway object.
Low Voltage Protection
The warning tone: The warning tone is set as an audible sound to help users judge abnormal conditions after turning on the power. 1. Fail to enter working mode after turning on the power: the routine of the throttle has not been set yet. 2. Continuing beeps: the pull rod of the throttle is not in the lowest position. 3. There is a short pause after a beep: the ESC can not detect normal throttle signals from the receiver. 4. There is a pause of one second after a beep: the voltage of the battery pack is out of acceptable limit (once the battery is connected, the ESC will carry out a self-checking and check the voltage of the battery.)

09 Safety Information |
|
DO
DO NOT
- Remove the propeller from the motor when programming or using the ESC for the first time.
- Use a battery that is in good condition and rated above the maximum current draw of the motor.
- Use a battery that is within the cell/voltage range of the ESC.
- If using new connectors, make sure the battery polarities are correct. Reversing the polarity will destroy the ESC. I.e., red (+) to red (+) and black (-) to black (-).
- Install ESC with good ventilation so heat can dissipate.
DO NOT
- Do not overload the SBEC by using too many or too big servos and other components. Drawing too many amps will cause the SBEC voltage to drop (brownout) and may cause the receiver to reboot during use.
- Do not get the ESC wet.
- Do not unplug the battery while the motor is spinning.
- Do not use a motor that exceeds the amp rating of the ESC. For max performance and ESC life, electrical standard is do not continually exceed 80% of rated value.
- Do not remove or modify any components on ESC, or it may cause permanent damage or data lose.
- Do not use broken, short-circuited and over-heated battery pack.
- Do not use substandard cables and connectors

Solution: Check and use a battery with voltage within the ESC's supported range.
Possible Cause #4: Incorrect battery type option selected
Solution: Change setting Battery Type to the correct option (LiPo / Li-ion is the default). See setting 11. Battery Type under section 07 Programmable Settings, and section 06 How to change the ESC Settings (Programming) on how to change the setting.
Issue #4: Motor doesn't run and emits a "Beep-Beep-Beep" warning tone every 2 seconds after powering up the ESC
Possible Cause #1: The ESC signal connector is plugged into the wrong channel on the receiver.
Solution #1: Confirm the ESC signal connector is NOT plugged into the "battery" channel on the receiver and plugged into the correct channel. Usually, it'll be the "throttle" channel for most receivers.
Possible Cause #2: The ESC signal connector is plugged upside down in the receiver.
Solution #2: Ensure the ESC signal connector is plugged in the correct orientation or swap the connector 180° in the receiver port and try again.
Possible Cause #2: No throttle output signal from the receiver.
Solution #1: Verify a proper connection between the signal wire and the receiver throttle channel.
Solution #2: Ensure the transmitter and receiver function properly and produce signal outputs.

Possible Cause #2: The ESC signal connector is plugged upside down in the receiver.
Solution #2: Ensure the ESC signal connector is plugged in the correct orientation or swap the connector 180° in the receiver port and try again.
Possible Cause #2: No throttle output signal from the receiver.
Solution #1: Verify a proper connection between the signal wire and the receiver throttle channel.
Solution #2: Ensure the transmitter and receiver function properly and produce signal outputs.
Issue #5: Motor doesn't spin and emits a continuous rapid beeping tone after powering up the ESC
Possible Cause #1: The throttle is not in the zero-throttle (neutral-throttle) position.
Solution #1: Move the throttle to the zero-throttle position. Bi-directional Throttle Mode is in the center of the range, and uni-directional Mode is at the very end of the throttle range.
Solution #2: Perform "Throttle Range Calibration Procedure" under section 04 First-time Use | Throttle Mode and Calibration. Also, see section 05 Normal Start up Procedure, for more information.
Possible Cause #2: ESC programmed with incorrect zero-throttle position (uni-directional instead of bi-directional or vice versa).
Solution: Reprogram the "Throttle Mode" setting as desired. Refer to Section 04 First-time Use | Throttle Mode and Calibration. Also, see section 05 Normal Start up Procedure.
Solution #1: Move the throttle to the zero-throttle position. Bi-directional Throttle Mode is in the center of the range, and uni-directional Mode is at the very end of the throttle range.
Solution #2: Perform "Throttle Range Calibration Procedure" under section 04 First-time Use | Throttle Mode and Calibration. Also, see section 05 Normal Start up Procedure, for more information.
Possible Cause #2: ESC programmed with incorrect zero-throttle position (uni-directional instead of bi-directional or vice versa).
Solution: Reprogram the "Throttle Mode" setting as desired. Refer to Section 04 First-time Use | Throttle Mode and Calibration. Also, see section 05 Normal Start up Procedure.
Issue #6: Motor doesn't work after powering up; ESC emits 2 long "Beep" and 2 short "Beep" sounds
Possible Cause #1: Throttle in maximum-throttle position and entering programming mode.
Solution: Move the throttle to the zero-throttle position. Bi-directional Throttle Mode is in the center of the range, and uni-directional Mode is at the very end of the throttle range. For more information, refer to Section 04 First-time Use | Throttle Mode and Calibration, and section 05 Normal Start up Procedure.
Possible Cause #2: The transmitter's minimum and maximum throttle points are programmed in reverse. I.e., the transmitter's throttle direction is reversed.
Solution #1: For Bi-directional Throttle Mode, the reversed throttle shouldn't be an issue as the motor will spin in the reverse direction. Try putting the transmitter in the full throttle position for an ESC setup with Uni-directional Throttle Mode. If the ESC follows the Normal Start up Procedure and doesn't enter programming mode, then you'll need to reverse the transmitter's max and min throttle points. Refer to the transmitter's user manual for more info. Then do a "Throttle Range Calibration" under section 04 First-time Use | Throttle Mode and Calibration. Also, see section 05 Normal Start up Procedure, for how the ESC should typically perform.
