YSIDO 1625 3500KV 4500KV 6000KV 7500KV 11000KV Brushless Motor & 20A ESC Combo Instruction Manual

1. Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of your YSIDO 1625 series brushless motor and 20A Electronic Speed Controller (ESC) combo. This high-performance system is designed for 1/24 and 1/28 scale RC mini cars, offering various KV options to suit different speed and torque requirements. Please read this manual thoroughly before use to ensure proper setup and safe operation.

2. Safety Information

• Always disconnect the battery from the ESC when not in use to prevent accidental motor activation.
• Ensure all connections are secure and properly insulated to avoid short circuits.
• Operate RC vehicles in open areas, away from people, pets, and obstacles.
• Do not touch the motor or ESC immediately after use, as they may be hot.
• Use only compatible batteries (2-4S LiPo) as specified for the ESC.
• Keep the motor and ESC away from water and moisture unless explicitly rated as waterproof.

3. Package Contents

Your YSIDO 1625 Brushless Motor & 20A ESC Combo package should include the following items:

• 1x YSIDO 1625 Brushless Motor (selected KV)
• 1x YSIDO 20A Electronic Speed Controller (ESC)
• Connection cables (as pictured)

4. Setup and Installation

4.1 Component Overview

The YSIDO 1625 Brushless Motor is a compact, high-performance motor available in various KV ratings (3500KV, 4500KV, 6000KV, 7500KV, 11000KV). The 20A ESC is designed to efficiently control the motor and is compatible with 2-4S LiPo batteries, featuring an SBEC for receiver power.

4.2 Wiring Diagram and Connections

Follow the diagram below for correct wiring of the ESC, motor, battery, and receiver. Incorrect wiring can damage components.

1. **Motor Connection**: Connect the three wires from the brushless motor to the corresponding three wires on the ESC. The order of these wires can be swapped to change motor rotation direction if needed.
2. **Battery Connection**: Connect the battery to the power input wires of the ESC. Ensure correct polarity (red to positive, black to negative). The ESC supports 2-4S LiPo batteries.
3. **Receiver Connection**: Connect the signal cable from the ESC (typically the one with three wires: signal, positive, negative) to the throttle channel (usually channel 2) on your RC receiver. The ESC's built-in SBEC will provide power to the receiver.

Secure all connections with heat shrink tubing or electrical tape to prevent accidental disconnections or short circuits during operation.

4.3 Mounting

• **Motor Mounting**: Mount the motor securely to your vehicle's motor mount using appropriate screws. Ensure proper gear mesh between the motor pinion and the vehicle's spur gear.
• **ESC Mounting**: Mount the ESC in a location that allows for good airflow to prevent overheating. Use double-sided tape or zip ties to secure it. Keep it away from water and excessive vibrations.

5. Operating Instructions

5.1 Initial Power-Up and Calibration

1. Ensure your transmitter is turned ON and the throttle trim is set to neutral (0).
2. Connect the battery to the ESC. The ESC will emit a series of beeps indicating cell count and readiness.
3. If the ESC requires calibration (refer to your ESC's specific manual if available), follow the manufacturer's procedure, which typically involves setting the throttle endpoints.
4. Test the throttle response. The motor should respond smoothly to throttle inputs from your transmitter. If the motor spins in the wrong direction, swap any two of the three motor wires.

5.2 Driving Your RC Vehicle

Once calibrated, you can operate your RC vehicle. Start with gentle throttle inputs to get a feel for the power. Different KV motors will provide different performance characteristics:

• **Higher KV (e.g., 11000KV)**: Generally provides higher RPM and top speed, suitable for speed runs on smooth surfaces.
• **Lower KV (e.g., 3500KV)**: Generally provides higher torque and longer run times, suitable for off-road or technical driving where control is more important than raw speed.

6. Maintenance

• **Cleaning**: Regularly clean the motor and ESC to remove dirt, dust, and debris. Use compressed air or a soft brush.
• **Inspection**: Periodically inspect all wires and connectors for signs of wear, fraying, or damage. Ensure motor bearings are smooth and free of grit.
• **Temperature Monitoring**: Monitor motor and ESC temperatures during operation. Excessive heat can indicate an issue (e.g., incorrect gearing, over-discharging battery, or component overload).
• **Storage**: Store the motor and ESC in a dry, cool place when not in use.

7. Troubleshooting

8. Specifications

8.1 YSIDO 1625 Brushless Motor

8.2 YSIDO 20A Electronic Speed Controller (ESC)

• **Continuous Current**: 20A
• **Battery Compatibility**: 2-4S LiPo
• **BEC Type**: SBEC (Switching BEC)
• **Recommended Age**: 14+ years

9. User Tips

• **Gearing**: Experiment with different pinion and spur gear combinations to fine-tune your vehicle's performance. A smaller pinion or larger spur will increase torque and reduce top speed, and vice-versa. Always monitor motor/ESC temperatures after changing gearing.
• **Battery Choice**: While the ESC supports 2-4S LiPo, consider the vehicle's original design and your driving style. Higher cell count batteries (e.g., 4S) will provide more power but also generate more heat and stress on components.
• **ESC Programming**: Many ESCs have programmable parameters (e.g., brake force, punch, timing). Refer to the ESC's specific manual for details on how to program it, often done via transmitter stick movements or a dedicated program card.
• **Water Protection**: If operating in damp conditions, consider adding additional waterproofing measures to the ESC and motor, even if they have some level of splash resistance.
