5. Setup and Installation

Follow these steps for proper installation of your ZTW Mantis Slim G2 15A ESC:

1. Connect to Motor: Connect the three motor wires from the ESC to the three wires of your brushless motor using the 2.0mm bullet connectors. The order of connection may affect motor rotation direction; if the motor spins in the wrong direction, swap any two of the motor wires.
2. Connect to Receiver: Plug the servo lead (signal cable) from the ESC into the throttle channel of your RC receiver. This is typically channel 3.
3. Connect to Battery: Connect your 2-4S LiPo battery (or 5-12NC battery) to the JST female connector on the ESC. Ensure correct polarity.
4. Secure the ESC: Mount the ESC securely in your aircraft, ensuring good airflow for cooling. Avoid placing it near sources of interference.

6. Operating Instructions

6.1 Throttle Range Calibration

For optimal performance, calibrate the ESC's throttle range with your transmitter:

1. Turn on your transmitter and set the throttle stick to its maximum position (100% throttle).
2. Connect the battery to the ESC. The ESC will emit a series of beeps.
3. When you hear the confirmation beeps (usually a long beep or a specific tone sequence), move the throttle stick to its minimum position (0% throttle).
4. The ESC will emit another series of beeps to confirm the minimum throttle position. The calibration is now complete.

6.2 Programming Modes

The ZTW Mantis Slim G2 15A ESC supports two main operating modes:

• Forward Only: Standard mode for fixed-wing aircraft.
• Forward and Reverse: For specific 3D/4D flying applications where reverse thrust is required.

Programming can be done via your transmitter's stick commands or more conveniently with the ZTW LCD Program Card G2 (sold separately). Refer to the program card's manual for detailed instructions on adjusting parameters such as battery type, cutoff voltage, timing, and brake settings.

7. Maintenance

• Keep the ESC clean and free from dust, dirt, and moisture.
• Regularly inspect all wires and connectors for damage or loose connections.
• Ensure adequate airflow around the ESC to prevent overheating, especially during prolonged use.
• Store the ESC in a dry, cool place when not in use.

8. Troubleshooting

If you encounter issues with your ESC, consider the following:

• Motor not spinning: Check all connections (battery, motor, receiver). Ensure the throttle is calibrated correctly. Verify the battery is charged.
• Erratic motor behavior/stuttering: This could indicate incorrect motor timing, a loose connection, or a damaged motor/ESC. Check connections and try adjusting motor timing if programmable.
• ESC overheating: Ensure sufficient airflow. Check for excessive current draw from the motor or an undersized propeller.
• No power to receiver/servos: Check the BEC output. Ensure the ESC is properly connected to the receiver.
• ESC beeps continuously: This often indicates a low voltage cutoff or an error code. Refer to the programming card manual for specific beep codes if available.

If problems persist, contact ZTW customer support for further assistance.

9. Warranty and Support
