Key features include:
- 865 precision-engineered building pieces.
- Designed by JK Brickwords, a renowned MOC designer.
- Mechanical transmission system that simulates orbital motion.
- Includes a detailed, full-color printed assembly instruction manual.
- Pieces are sorted into different bags to facilitate easier identification and assembly.





Setup and Assembly
The CaDA Master C71004w kit requires assembly. Follow the steps outlined in the included full-color printed instruction manual. All 865 pieces are divided into separate bags to assist with organization and ease of finding components during the building process.
Important Tips:
- Unpack all bags and organize pieces by type or color as suggested by the manual.
- Refer to the detailed diagrams in the instruction manual for each step.
- Ensure all connections are secure to guarantee proper mechanical function.
- Take your time and enjoy the building process.
Operating Instructions
Once fully assembled, the CaDA Master C71004w model can be operated manually to demonstrate the orbital mechanics of the Earth, Moon, and Sun.
To operate the model:
- Locate the handle on the side of the base.
- Turn the handle clockwise.
- As the handle is turned, the turntable will begin to rotate counter-clockwise, and the Sun, Moon, and Earth models will start their respective orbital movements, simulating their paths through the year.
Observe the intricate gear system and how each celestial body moves in relation to the others.
Maintenance
To ensure the longevity and proper function of your CaDA Master C71004w model, follow these maintenance guidelines:
- Cleaning: The manufacturer states the product is machine washable. For best results, it is recommended to gently hand wash individual plastic pieces with mild soap and water, then air dry thoroughly. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the assembled model or disassembled pieces in a clean, dry place away from direct sunlight and extreme temperatures to prevent warping or discoloration.
- Handling: Handle the model with care, especially the moving parts, to prevent damage to the gears and connections.
Troubleshooting
If you encounter issues during assembly or operation, consider the following common problems and solutions:
- Missing Pieces:
Carefully re-check all packaging and sorting bags. Sometimes small pieces can be overlooked. If pieces are genuinely missing, contact CaDA customer support or your retailer with proof of purchase and the specific part numbers needed.
- Model Not Rotating Smoothly / Gears Skipping:
This often indicates an issue with gear alignment or a loose connection. Review the assembly steps related to the mechanical transmission. Ensure all axles are fully inserted and gears are properly meshed without excessive friction. Some users have found that adding small washers to the Sun's axle can improve gear alignment if there are manufacturing tolerances.
- Difficulty Identifying Parts in Manual:
While the manual is detailed, some diagrams might be challenging. Pay close attention to the number of studs, pinholes, and unique shapes of pieces. Compare the physical pieces directly with the illustrations. Online communities or fan-made build videos might offer additional visual guidance.
