4. Setup & Assembly
General Connection Guidelines:
- Ensure all components are clean and free from debris before assembly.
- Connect motors, battery boxes, and receivers using the provided wires.
- For remote control functionality, ensure the receiver and remote control are from the same set to guarantee frequency compatibility.
- Pay attention to the polarity when connecting battery boxes and motors.
Important Safety Warning for Servo Motor:
The Servo Motor CANNOT be connected directly to a battery box. It must be connected through a receiver. Direct connection to a battery box will cause the motor to burn out and become permanently damaged.

Battery Installation:
- AA Battery Box: Requires 6 AA batteries (not included). Ensure correct polarity when inserting batteries.
- AAA Battery Box: Requires 6 AAA batteries (not included). Ensure correct polarity when inserting batteries.
- Lithium Battery Box: This unit is rechargeable. Use the appropriate charging cable (if included) and power source.
Example Connection Diagram (IR Control):

In this setup, the AA Battery Box powers the IR Receiver. The IR Receiver then controls Motor 1 and Motor 2 based on signals from the IR Remote Control. Ensure the remote control and receiver are set to the same frequency.
Extension Wire:

The 25cm Extension Wire (8886) can be used to extend the reach between components, allowing for more flexible model designs.
5. Operation
IR Remote Control:
Once all components are correctly connected and powered, use the IR Remote Control to operate your motorized creations. Ensure the remote control and receiver are on the same frequency channel. The remote typically features directional controls for motors and speed adjustments (if using an IR Speed Remote Control).
APP Control (for 8CH Mould King APP Control Set):
For bundles including the 8CH Mould King APP Control Set, download the corresponding application to your smartphone or tablet. Follow the in-app instructions for pairing the control set via Bluetooth and operating your models. The app typically offers more advanced control options and programming capabilities.

6. Maintenance
- Cleaning: Use a dry, soft cloth to clean the components. Avoid using water or chemical cleaners, as these can damage electronic parts.
- Storage: Store components in a dry, cool place away from direct sunlight and extreme temperatures.
- Battery Care: Remove batteries from battery boxes if the product will not be used for an extended period to prevent leakage. Recharge Lithium Battery Boxes regularly to maintain battery health.
- Small Parts: Keep small parts away from young children to prevent choking hazards.
7. Troubleshooting
Common Issues & Solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not responding | Incorrect wiring, low batteries, incompatible remote/receiver, motor burnout (especially Servo) | Check all connections. Replace or recharge batteries. Ensure remote and receiver are compatible and on the same frequency. Verify Servo motor is connected via receiver. |
| Remote control not working | Low remote batteries, incorrect frequency setting, obstruction between remote and receiver | Replace remote batteries. Adjust frequency channel. Ensure clear line of sight to receiver. |
| APP control not connecting | Bluetooth not enabled, app not installed/updated, incompatible device | Ensure Bluetooth is on. Install/update the official Mould King APP. Check device compatibility. |
| Servo motor burned out | Direct connection to battery box | This is irreversible damage. Always connect Servo motors through a receiver. |
8. User Tips
- Compatibility: While these components are Legoeds-compatible, always ensure you use the receiver and remote control from the same manufacturer (Wishiot/Mould King) to avoid frequency incompatibility issues.
- APP Control: For the 8CH Mould King APP Control Set, search for the official Mould King app on your device's app store. This app provides dedicated control and potentially programming features.
- Battery Life: Consider using rechargeable batteries for AA/AAA battery boxes for long-term cost savings and environmental benefits.
- Creative Building: These power functions are designed for MOC (My Own Creation) projects. Experiment with different motor types and gear ratios to achieve desired speeds and torques for your models.
