Well it would depend on the way you gear it to. If you racing it on a 9xl I would go for the bigger quark so no worries will running the piss out it. The 7020 will run the 9xl but have to watch gearing and it won't take a lot of hard driving. I have a video on the 9xl on 12 cells if you look in the rc pics file. It don't do to shabby.
