Depends on what your running and where. Brushed or Brushless? I have lots of setup sheets for CRC 1/12 scale and lots are available online. Still they are just a base setup. Best to just look at what other guys you are running against are doing. Or search your car model online for suggested setups. 1/12th scale are pretty simplistic cars and much more forgiving than 1/10 touring in my opinion. I can take just about anyone's setup around a track and look like I know what I'm doing
