What is that all about on the associated set up sheets?

Can someone explain or send me a link to something that will show me what it is?

I think he has modified caps similar to the Losi's with a bleeder hole at the top, but I'm pretty sure you can also just run a standard emulsion style setup with the center of the bladders cut out w/ the regular caps.

What he said. You really don't have to have the bleeder screw in the shock cap to run emulsion shock. They bleed really easily without the screw in the cap; I honestly don't see a real need for it.
