Please do. :-)
One thing I think I mentioned is that google etc. is horrible about providing answers.
Slot cars share a large bit of their vocabulary with R/C cars, static models and of course real cars.
I remember that until I found forums I wasn't even sure why there were 3 types of Scalextric track (Classic, Sport and Start).

I HATE everything being tracked and used against you in the form of advertising but for some reason slot car stuff gets buried.

To be fair there is also a general problem with information on  Internet.
When I started building computers in the early 90's it was fairly easy to find websites with very specific, step-by-step instructions on how to do things. We almost never had pictures!
If I upgraded my 75 Mhz Pentium to 100 on my Packard Bell it was pretty easy to find the info and the info was easy to follow.

My last computer I built was in 2005 and when I even try to figure out what CPU goes on what motherboard I give up.
Everything is full of advertising and forums are so full of half-baked, poorly written chunks of text that I have no clue.

I think that is part of the problem when searching on slot car related topics. Google panics and throws everything at you that might have even a one millionth chance of being right... and then people give up..
