I was thinking of getting the Kanai II but I cant find any break down of the parts it comes with so I wouldnt know what hop up parts I would have to buy. My other car is an Inferno 7.5 RTR and it came with aluminum chassis. Car was pretty fast out of the box, I would say mid 40's and it still has stock buggy tires on it, im sure it would be a bit faster with road tires.
