Well as a side hobby i like to design rc cars in cad (Solidworks).
I have been looking for a site that has part files, but haven't found one.

I started a site called [link=http://transworldrc.com]TRANSWORLDRC.com[/link] where i am going to let people download my files.
If you have some files in .step, .igs, Solidworks formats that you would like to share contact me here or on that site and i will make them available.

Also If you know of any other sites that may offer cad model files post up a link

Thanks in advance.
