I was intrigued by the suspension setup. That was kind of innovative, though I don't know how adjustable it really is. The Achilies heel looks like the tie rod for the shocks that run diagonal from the lower arm to the cantilever. Looks vulnerable.
The electrinic shifter thing, well, just something else to get wet and burn up.
The big improvement looked like the drive shafts.
And what was it they said about the roational mass of other MT's tranny's with reverse? Bulky and unneeded parts or something. Hell, when the Savage is in forward, the reverse module doesn't do much in that regard.
what would have made the Revo alot more interesting would have been say a 25% increase in size, with a Hyper 21 8 port or Picco .26. Now that would be badass. Well, ditch the electronic shifter, put some real underbody protection on it, metal CVD's, and maybe move the shock connecting rod behind the arms. Then it would be basass.
Who knows, the concepts may be proven and we'll see more F-1 suspension setups in out 1/8th buggies soon.
