My son has a Losi XXX-SCT and I find that for the most part, my Fury can hang with it. The dBoots tires hold me back. They are just a little to hard of a compound. I agree that Arrma is letting the hobbyist down by not releasing upgrade options to the same degree as Traxxis or Losi. The major aftermarket guys are also shying away from Arrma because they don't have a large enough market share to target (yet). I do wish Arrma would standardize their rim diameter to match other brands to open up our tire options, or make some alternative compound/tread design tires to buy for their proprietary rim designs.
