Re: New to the forum & excited to say hello!
Your project sounds interesting and involved. I would suggest re-posting the same question to the forum at large, in your own thread and give it a name that describes what the project is or the kind of help you're looking for. Your English is very good, by the way. Best of luck in your endeavor.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
