I haven't seen an equipment list from the worlds yet, but i'm sure the current winners sponsors will find a way to get it all over the place soon enough!
Of course Cavalieri, Amezcua and others have proven they can take any of the top brands to the winners circle, just like all the top drivers can. (Otherwise it wouldn't be so easy for them all to move around alot,
I remember at the first Losi race everyone thinking it was so awesome that Cavalieri dominated and won all the classes he ran in his first year with Associated. Those of us who were there the year before were like, "he Tqed and won all the classes with TeamLosi last year too."
But the loyalty some customers will keep is awesome for the manufacturers who benefit from it.
Whatever brand we use now, is "The best!"
