HOBBYWING Skywalker HV 130A / 160A OPTO V2 Brushless ESC Instruction Manual

1. Introduction

Thank you for purchasing the HOBBYWING Skywalker HV 130A / 160A OPTO V2 Brushless Electronic Speed Controller (ESC). This high-performance ESC is designed for demanding RC airplane applications, offering reliable power delivery and advanced features. Please read this manual thoroughly before installation and operation to ensure proper use and maximum enjoyment.

2. Features

• High-performance 32-bit ARM M4 chip set for extremely high operational frequency and motor control.
• Supports up to 120 MHz and 300,000 PRM (for 2 Pole motors).
• Great flexibility for 60-74" 3D fixed wing motors.
• DEO Technology / Active Freewheeling for fast, smooth throttle response, improved stability, lower ESC operational temperatures, and longer flight times.
• Search Mode feature allows the pilot to activate the ESC to emit an audible beeping tone from the motor, aiding in aircraft recovery in visually impaired areas.
• OPTO design (No BEC) for high voltage applications (6-14S LiPo).
• Programmable parameters via LED Program Box or transmitter.

3. Setup and Installation

Careful installation is crucial for the safe and efficient operation of your ESC. Ensure all connections are secure and properly insulated.

3.1 Wiring Connections

1. Motor Connection: Connect the three output wires from the ESC to the three phase wires of your brushless motor. The order of connection may affect motor rotation direction. If the motor spins in the wrong direction, swap any two of the ESC's output wires.
2. Battery Connection: Connect the red (+) and black (-) input wires of the ESC to your LiPo battery pack. Ensure correct polarity to prevent damage. This ESC supports 6-14S LiPo batteries.
3. Receiver Connection: Connect the signal cable from the ESC to the throttle channel of your RC receiver. This ESC is an OPTO version, meaning it does not have a built-in Battery Eliminator Circuit (BEC). You will need a separate BEC or receiver battery to power your receiver and servos.

3.2 Mounting

Mount the ESC in a location that allows for adequate airflow to prevent overheating. Use double-sided tape or zip ties to secure it firmly within the aircraft. Avoid mounting near sensitive electronic components that could be affected by electromagnetic interference.

4. Operating Instructions

4.1 Initial Power-Up and Calibration

1. Ensure your transmitter is on and the throttle stick is at its highest position.
2. Connect the main battery to the ESC.
3. Wait for the ESC to emit a series of beeps indicating cell count detection.
4. Once the beeps stop, move the throttle stick to the lowest position. The ESC will emit another series of beeps to confirm throttle range calibration.
5. The ESC is now armed and ready for flight.

4.2 Programmable Parameters

The Skywalker HV ESC offers several programmable parameters to fine-tune its performance to your specific aircraft and flying style. Programming can be done using an LED Program Box or through your transmitter.

The following table outlines the programmable items and their available values for the 130A & 160A models:

4.3 Special Features

• Search Mode: This feature allows the pilot to activate the ESC to emit an audible beeping tone from the motor. This is useful for locating and recovering your aircraft in areas where visual contact is lost.
• DEO Technology / Active Freewheeling: This technology optimizes drive efficiency, resulting in faster and smoother throttle response, improved stability, lower operating temperatures for the ESC, and extended flight times. For 3D aerobatics, it is recommended to turn off this function for specific control characteristics.

5. Maintenance

Regular maintenance helps ensure the longevity and reliable performance of your ESC.

• Keep Clean: Regularly clean the ESC to remove dust, dirt, and debris, especially from the heatsink fins, to maintain optimal cooling.
• Inspect Connections: Periodically check all wiring connections (motor, battery, receiver) for looseness, corrosion, or damage. Secure any loose connections and repair or replace damaged wires.
• Avoid Moisture: Keep the ESC dry and away from moisture. If it gets wet, ensure it is completely dry before reapplying power.
• Temperature Monitoring: During operation, monitor the ESC temperature. If it consistently runs hot, consider improving airflow, reducing propeller size, or checking for motor issues.

6. Troubleshooting

If you encounter issues with your ESC, refer to the following common troubleshooting steps:

• No Power/No Response:
  • Check battery connections and ensure the battery is charged.
  • Verify the ESC's signal cable is correctly plugged into the receiver's throttle channel.
  • Ensure your separate BEC or receiver battery is powered on and functioning correctly (since this is an OPTO ESC).
• Motor Not Spinning/Erratic Behavior:
  • Re-calibrate the throttle range (see Section 4.1).
  • Check motor phase wire connections for continuity and proper contact.
  • If the motor stutters, check the timing setting on the ESC. Adjusting the timing may resolve the issue.
  • Ensure the motor is not damaged or jammed.
• ESC Overheating:
  • Ensure adequate airflow around the ESC.
  • Check if the propeller is too large or if the motor is drawing excessive current.
  • Verify that the motor is not overloaded or partially seized.

8. User Tips

• Propeller Matching: Always ensure your propeller is appropriately sized for your motor and ESC combination. An oversized propeller can lead to excessive current draw and ESC overheating.
• Battery Health: Use high-quality LiPo batteries in good condition. Damaged or underperforming batteries can cause inconsistent ESC behavior.
• Signal Integrity: Keep the ESC's signal wire away from high-current wires (battery and motor wires) to minimize electromagnetic interference with the receiver.
• Firmware Updates: Check the HOBBYWING official website periodically for any available firmware updates for your ESC model, which may offer performance improvements or bug fixes.

9. Warranty and Support

For warranty claims, technical support, or further assistance, please contact the seller (U-Angel-1988 RC Store) or the manufacturer (HOBBYWING) directly. Keep your proof of purchase for any warranty-related inquiries. Specific warranty terms and conditions may vary by region and retailer.
