I dont think there is any thing new about a X2 cobra $500+ is just stupid IMO
I think AXE should come out with a 3 or 5 port race with a $220 to $250 price tag like most of the motors now a day with focus on fuel milage and they will start to sell again. The Mamba is ok but not much of a race motor, I think my friend could just make a 6min qualifier with his. I ran rossi motors in the 90's remember the ceramic piston gold head.
