There was a video on You Tube(it been removed for some reason) of a SC10 running against an RC8 at OCRC. The SC10 was giving the SC8 all it could handle. It took the lead several times as a matter of fact.
W/ the inherent high CG the Slayer is straddled with and depending on the track. I think the SC10 would hand you your butt.
That said, I think a brushless 4wd SC truck is just sick, To bad we can't get Traxxas to produce a factory version.
