Since I never found a good setup which suited my driving style and the track, I've read page up, page down at this site.

I beleave many have seen this site before, but it is very good since it gives a good explanation what happens when you adjust the different wheel angles etc.
At the start of this years season I had no idea what to adjust, but in the end of the season I had a pretty good car that worked much better than before.
I totally agree that Kyosho should support their drivers with the top drivers setups. It is easy to loose interest and change brand if it is to hard to make your car work well and go fast.
