Im runing Yokomo Nitro GT4 for the last 4 years and have already the Limited Edition one and its a hell of a good kit and still competitive (and sometimes a lot better) kit v/s the MTX3 and new S710 from Serpent and Mugen.
Now, i love to try new things ... the R40 its competitive right out of the box or it NEEDS of hopups to be a racer car ?
thanks a lot ...
