I am not into Rock crawling but I think the crawlers are pretty cool. I would own one just to marvel in the coolness of it.
Anyways, I am reading a review about the Kyosho Rock Force 2.2 in one of the rc car mags and they made a statement about changing the body out to a legal USRCCA body (8x3x3.75)for competition. How does the body give you an advantage in Rock Crawling? Aerodynamics aren't a factor. Overhang from the chassis? Is this just a rule to annoy people or maybe a rule to just have a rule?
