I found this site excellent for setups:
http://www.petitrc.com/setup/kyosho/...UltimaRB5.html
There ae quite a few, and you can even see what tyres, and different surfaces people are running on, and get a feel for what things remain the same on the car, and what changes thr top boys make to tune the car in.
If you racing inside, the some yellow minipins all round, or some yellow stagger ribs for the front might be advisable as they keep the car nice and safe. See what indoor setups say on the petit site.
Hope this helps
