Us lipo thicko noob's need as much help as we can get.
While browsing through your link I got 1/4 down the page and saw this..."These 4 packs went to the Chaos!! and gave me a significant weight saving. !"
I clicked on the Chaos link and scrolled down, then found (to my amazment!!) just what I was looking for...
Your ABS construction.
I was just about to post on my own thread and ask if anyone could recommend something to build a box like this?
Looks like this ABS stuff is the very thing.
