Additionally, I was trying to provide context as well. Very different conclusions are drawn from the statements '1/2" cantilevered axles didn't hold up in our experiments' versus '3/8" cantilevered axles are fine for our prototypes'. Indeed, the original post didn't have anything about the context of competition or extreme environments, however it is implied by the fact that there's a good chance a third party reader who arrives at this post via search will take the information as fact during the build season (regardless of how illogical that can be, does anyone really have time to 'experiment' during the build season?).

I should have further explained my point I suppose. Saying 1/2" shafts will work is just as dangerous as saying 3/8" shafts will work. The diameter of your wheel, how far it's cantilevered, how many wheels you have, what you're driving over, etc... will all effect the size you really need.
I'm just as guilty of any of doing this, I just hate the thought of a kid browsing chief and seeing, "1/2" axles! they work, we're doing it!", then spend a whole season busting axles. The other end of the spectrum is true as well, but less damaging, I'd dislike to see a team waste a half pound for no net gain.
Before we can really quote shaft sizes, we need more information about their specific shaft setup and design.
