RE: Strictly On Road Baja..........
Half the fun of this hobby is wrenching and customising your RC. People have different tastes and different locations, for instance tarmacs were a bad choice for me since the only good roads are right outside peoples houses where i can't run, plenty of off-road terrain and beach sand for me to play on though. Miami might have quite different roads/terrain to play on coupled with his own personal tastes for modifiying make an on-road baja quite enjoyable for him.
I think the Baja frame has alot of potential to be a roadster, but something needs to be done about its shocks, a laydown F1 style system like the revo has would be quite awesome, looks to be plenty of room on the front and rear upper decks to do something like that, not my cut-o-tea since i spend more time offroad then on but for someone serious it'd definaly be cool and with the kind of speeds Miami likes to do it could get rid of some wind resistance.
