BAUSTIN, I'm glad that stuff is still proving helpful - it's now about 10 years since it was first put together and keeps popping up all over the place.
As you pointed out the material was really aimed at beginning/starting out racers. it's not intended to be the be-all and end-all of suspension tuning for experts - but some sound basics for those getting a taste of how to go racing.
There is a touring car version as well which we keep on our current website at
www.actionrc.com.au (look for "R/C Book" link).
Cheers
Scott Guyatt
PS both versions could do with some updating in terms of equipment (eg electronics, tyres etc) but the basics are still there. Apologies - I never seem to get the time to update the documents!
