Vintagelosi.com copied a large selection of setup documents from the Losi.com site.
Most are grouped into one compressed file by model name. You can download the file and then it should uncompress into a folder that contains all the setup sheets for that model.
Most contain a blank setup sheet and multiple racer setups from the past.
