I have an RS4 2 right now and I love it. I know there's now the RS4 3. But How many different kinds of RS4 nitro cars are there? I'm guessing there's an RS4 1 but not really sure

. I've also heard of the RS4 Racer, Sport, Rally, Super and I don't know what else. Just wonderin' where my RS4 2 falls when it comes performance among these HPI nitro cars. :stupid:
