First off the wiki is looking awesome! So much new stuff being added thank you!!

So I took a look at the foam that came inside the case of my revo, it's a tiny tiny piece of black stuff, quite dense, the large chunk shown in the wiki looks a lot less dense, where can I get or what sort of foam is the "right" sort of foam from for the baro?

thanks

You want "open cell foam", and you want the right amount of it.  A small amount of air can pass through it.
If you use too thin a piece, it passes too much air, as if it isn't even there.
If you use too thick a piece or compress it too much it blocks the air flow too much.
