Vision: a complete exposition of the logic and beauty of mechanical mechanism, with an exceptional focus on how they are presented.

.Reduction Degree: Use a historical classic invention or product as the design prototype, explain the fundamental operating principle, and logically demonstrate the fundamental purpose of the machine. The representative classic works in the history of industrial science and technology served as the source of inspiration. scale model and extreme reductionism

.Expansibility: Each product has a distinct independent structure and function, but it can also be expanded to upgrade, combine, and modify the power system using the appropriate kit or do-it-yourself modification.

Fun to Assemble: The user must put together the machine's pieces and components when using the original product. The entire procedure resembles a professional assembly line, which takes more than 3 hours to complete the assembly. The level of difficulty is 4.5 stars, which is challenging and rich in experience.

Power: Use an electric motor instead of a conventional gasoline one to help the product operate smoothly without damaging it. Using a lithium battery with a 500MAH capacity, it operates for at least 30 minutes.
