Well if you think the revo is too big then the list you gave above will also be too big, i'm talking about the savage list.
Trust me on 1 thing, don't go for a 1/10 scale after coming from 1/8 scale. Even though the revo is supposed to be a 1/10 it truely is a 1/8.
Instead of going for on of these "Hpi rush evo or firestorm , thunder tomahawk 1/10 , do hyper have a truggy 1/10" do yourself a favour and get yourself a 1/8 buggy!
Much much tougher, more play time, cheaper in long run, less fixing and spending .... it is roughly the same size as a 1/10 maybe a little bigger.
