10-Pin Connector Details:

• M1, M2, M3, M4: Motor signal outputs.
• CURR: Current sensor output.
• TELE: ESC telemetry.
• BATT, BATT: Battery voltage input for FC power supply.
• GND, GND: Ground connections.

5. Start-up and Throttle Calibration

Always remove propellers before any calibration or testing for safety. Incorrect throttle calibration can lead to unpredictable motor behavior.

5.1 Normal Start-up Process

1. Power up the ESC.
2. Throttle up detected (ESC recognizes high throttle).
3. Zero throttle detected (ESC recognizes low throttle).
4. Ready to fly.

5.2 ESC Throttle Calibration

1. Power up the ESC while holding the throttle stick on your remote control at maximum.
2. The ESC will detect the throttle signal.
3. The ESC will enter a mode to detect the maximum throttle.
4. The maximum throttle is set.
5. Move the throttle stick to the minimum position.
6. The minimum throttle is set, and calibration is complete.

6. Programming Parameters

The RUSH BLADE ESC offers various programmable parameters to fine-tune its performance. These settings are typically adjusted via the BLHeliSuite32 software.

• 1. Motor Power: Adjusts the maximum motor power output. Default is 100%. This is the maximum power that is allowed when ramping up at low RPMs and during start-up. For low RPMs, the maximum power to the motor is limited. If there is motor desyncing, try to reduce this parameter.
• 2. Direction: Motor direction can be set to Forward (Fwd), Bidirectional, or Bidirectional Rev. This parameter is used to limit the power applied during direction reversal. During startup, the actual applied power depends on the motor type. If there is motor desyncing, try to reduce this parameter.
• 3. Demag Compensation: This feature protects against motor stalls. It is recommended to keep this enabled.
• 4. Motor Timing: Adjusts the motor timing. Default is 15 degrees. Incorrect timing can lead to motor desync or overheating.
• 5. PWM Frequency: Adjusts the PWM frequency. Default is 24KHz. Higher frequencies can provide smoother operation but may increase heat.
• 6. Startup Power: Adjusts the motor startup power. Default is 100%.
• 7. Temperature Protection: Enables or disables temperature protection. If enabled, the ESC will reduce power or shut down if it overheats.
• 8. Low RPM Power Protection: Enables or disables low RPM power protection. If enabled, the ESC will reduce power or shut down if it detects low RPM issues.
• 9. Voltage Protection: Enables or disables voltage protection. If enabled, the ESC will reduce power or shut down if the battery voltage drops below a set threshold.
• 10. Current Protection: Enables or disables current protection. If enabled, the ESC will reduce power or shut down if the current draw exceeds a set limit.
• 11. Brake On Stop: Sets the strength of the brake when the motor stops.
• 12. Beep Strength: Sets the volume of the ESC beeps.
• 13. Beep Frequency: Sets the frequency of the ESC beeps.
• 14. PWM Frequency: PWM frequency can be programmed between 16KHz and 96KHz. Higher PWM frequency can provide smoother operation but may increase heat.
• 15. ESC Response: Adjusts the ESC response time.
