Buggy Rear Tower
mafiaracers - My understanding with the buggy rear tower on the XXX-T is that as you were saying, it lowers the cg of the rear end, but more importantly helps prevent the excessive roll/dumping, that the losi truck is prone to...
Not that the truck is terrible (its my all time favorite r/c!!!), but from a physics/dynamics standpoint it just makes it that little bit better!
Aaron, maybe you can confirm/deny this....
