This significantly improves control response;\u003c\/li\u003e\n\u003cli\u003eVariable PWM: When enabled, the ESC dynamically adjusts the PWM frequency based on the motor’s actual speed. This provides smoother operation at low speeds and optimizes efficiency at high speeds;\u003c\/li\u003e\n\u003cli\u003eBi-directional (Fwd\/Rev): Allows the motor to rotate both forward and backward. The motor stops at throttle neutral; pushing the throttle causes forward rotation, and pulling the throttle causes reverse rotation. Suitable for 3D aircraft, car models, or RC cars with a “reverse flip” (backflip) function;\u003c\/li\u003e\n\u003cli\u003eStuck Rotor Protection: When the ESC detects that the motor is jammed by a foreign object and cannot rotate, it automatically cuts off the current to prevent burning out the motor or the ESC board;\u003c\/li\u003e\n\u003cli\u003eBrake On Stop: When the throttle is reduced to 0, braking force is applied to the motor to bring it to a rapid, complete stop. This is commonly used in gliders with folding propellers to prevent the propeller blades from continuing to rotate and creating drag during unpowered gliding;\u003c\/li\u003e\n\u003cli\u003eStall Protection: Provides a protection mechanism to attempt recovery or shutdown when high load causes the motor and ESC to lose synchronization (desynchronization);\u003c\/li\u003e\n\u003cli\u003eSinusoidal Startup: Uses a sinusoidal algorithm to drive the motor during startup, resulting in a smoother start-up process and reducing startup noise and vibration;\u003c\/li\u003e\n\u003cli\u003e30 ms Telemetry: Sends ESC status data (such as RPM, current, voltage, and temperature) to the flight controller via the telemetry port every 30 milliseconds;\u003c\/li\u003e\n\u003cli\u003eUse Hall Sensors: If using a “sensor-equipped brushless motor” with Hall sensors, selecting this option provides extremely precise low-speed control (commonly used in rock crawlers, etc.);\u003c\/li\u003e\n\u003cli\u003eTiming Advance: The motor timing advance can be set to Auto or 1–31°. A medium timing advance value is typically suitable for most motors, but if the motor runs unevenly, try adjusting the timing advance. For some high-sensitivity motors, the commutation demagnetization time is relatively long, especially during low-speed operation. In such cases, the motor may stall or run unevenly when throttle is rapidly increased. Increasing the timing advance helps mitigate this issue, as a higher advance angle allows for a longer commutation demagnetization time;\u003c\/li\u003e\n\u003cli\u003eMotor KV: The KV value represents the increase in no-load speed per 1V increase in voltage. The KV value is generally set near the motor’s rated KV value to achieve optimal performance;\u003c\/li\u003e\n\u003cli\u003eMotor Poles: Refers to the number of magnetic poles (magnets) inside the motor’s rotor. The ESC must know the correct number of poles to calculate the motor’s actual speed; an incorrect setting will result in abnormal telemetry speed readings;\u003c\/li\u003e\n\u003cli\u003eStartup Power: Used to set the initial torque during motor startup. Setting this too low may cause the motor to fail to start or exhibit abnormal vibration, while setting it too high may result in an overly aggressive startup, which in severe cases could cause propeller blades to fracture or components to burn out;\u003c\/li\u003e\n\u003cli\u003ePWM Frequency: The frequency at which the ESC controls the motor pulses. Higher frequencies reduce high-frequency noise and provide smoother operation, but the ESC is more prone to overheating (this parameter generally does not need to be adjusted);\u003c\/li\u003e\n\u003cli\u003eBeep Volume: The volume of the alert sound emitted when the ESC powers on or triggers an alarm. Note: The ESC itself does not have a speaker; it generates sound by inducing micro-vibrations in the motor windings via high-frequency current (this parameter does not require adjustment);\u003c\/li\u003e\n\u003cli\u003eSine Startup Range: Determines the speed range within which Sinusoidal Startup remains active after takeoff; beyond this range, the system switches back to conventional square wave\/trapezoidal wave drive;\u003c\/li\u003e\n\u003cli\u003eSine Mode Power: The amount of power supplied to the motor during the Sinusoidal Startup phase;\u003c\/li\u003e\n\u003cli\u003eRunning Brake Level: The amount of braking force actively applied by the ESC when the throttle is reduced (but not fully released to 0) during flight or driving;\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBattery Management: Ensure the battery is properly balanced to prevent overvoltage or over-discharge in any single cell;\u003c\/li\u003e\n\u003cli\u003eNever reverse the positive and negative terminals\u003c\/li\u003e\n\u003cli\u003eCorrect Power-On Sequence\u003c\/li\u003e\n\u003cli\u003eWait for the self-test to complete: After powering on, wait for the ESC to complete the throttle signal detection and initialization self-test (indicated by a normal beep).
