The [link=http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11598]4000mAh hardcase turnigys[/link] are a bit smaller than the 5000mAh versions, and the wires come out of the top of the pack, rather than the end. It's a much more convenient setup, so I ordered a pair for my evader. I'll just use the 5000mAh packs in my stampede.
