Are you searching for a Redcat Gen8 Parts Diagram? If so, check your instruction manual...you know, that booklet that came with your truck but you didn't read. Just kidding, but really there is a parts diagram toward the back of the instruction manual.
If you've lost yours, you can always download a new copy by visiting the Gen8 page then clicking on the resources tab. I try to have links to all instruction manuals on the vehicle pages.
Here's a quick look at the Gen8 Parts Diagrams for you as well.
Hope it helps.
