I like the modified Slash just fine but the HPI should handle better and should be just as tough as the Slash.
I've raced Losi 2wd for years but the SC truck yuk and I never did care for the spindly Associated Trucks.
TheHPI looks to be a best of both worlds, handling and toughness.
Too bad about that cheap radio though wish it was a kit

Will not race 4wd anything. I like the challenge of 2wd.
But hey that's just me.
