RE: the OFFICIAL R-40 thread !
Just in case you guys are interested. Visit HPI.com, and look up the R40. There's a set-up sheet that show's what Atsushi Hara used to win... Though it doesn't work quite as well at my track, it did help me learn about the suspension settings on the car. Also, the XXX losi tuning guide is a great reference point, filled with useful info.
