Yep, and just think, RB was making low center of gravity (L2G) cooling head designs back 2006-2007 before anyone else. They even had a super light Magnesium cooling head option back then, (didnt work great), but still innovative. Too bad they aren't made like those old RBs any longer. RB WS72 is still my favourite buggy motor of all time, it just ran so well in that old Xray buggy.
