One more thing that I would suggest would be to expand the specific car threads to sub-threads.
Let's take my example, when I started in 1/10 EP cars with a losi xxxs a few months ago (I am an 8th scale off roader) I had to go through thousands of posts so as to get the info I needed, ending up asking probably the same things that were answered a couple of thousand posts behind.
So a format of the type
1/10 on road
----Team Losi
----------XXXS
-------------How do I ........?
-------------Diff problem
----------JRXS
-------------How do you......up your..... ?
----Tamiya
----------TRF415

1/10 off road
----Associated
----------B4
----------T4


and so on and so forth



Anyway it is up to futureal, whose time, I and we should all appreciate.

Just my 2 cents
