at this point, it really doesn't matter really. I already bought the replacement arms, and short of yamato air mailing me a shiny set of machined aluminum replacement arms, there's just no way I'm buying any more VF-0 toys. It's a shame though, I really do like the VF-0, and would love to buy more, but they're just all ticking time bombs. The whole arm needs a redesign and better materials. The workers need to understand that they can't just "pop" the assembled shoulder onto the ball joint, as I'm 99.9% certain this is the intial cause of the stress marks and cracks.
In the end, I'm just curious to see what yamato told graham.
