Actually the slash4x4 is not that bad, if we treat the tunning like others SCT like having a good tire for track, find tunning of suspension/ chassis/ differential etc, the car can do very fast in corner also. Traxxas just made an impression on it straight power on its advertising but my experience of the slash 4x4 in mx track is that this car is capable enough to run fast in corner, just its marketing position will make people not willing to spend further money to tune the car to fit the track.
