So a day ago, I published a post asking how to make a unique car system: I suggest reading that first post before the current one How to make a toy race car system
There I wanted to know how to make a toy race car system, I got a couple of answers(but it was about more in-depth stuff). Here I would like to know WHERE TO START. That is how to make the first step in this situation and what it can be. Do I have to figure out how to make a basic car and then improve it? If so, can I get links to articles about it? In general, I hope you understand the question.
I would also like to get more or less step-by-step instructions about all this. For example, what should I do after creating the basic machine itself and so on? I hope for an answer) If anything do not forget to read the previous part of the post.
P.S. I would like to express my gratitude to Fittergem1000, and Outdoorrumble66 for help with more in-depth questions
