Guys, I know very little, in fact next to nothing about the Yamato display arm. I've no idea about the material, strength etc.
It's a project completely controlled by Yamato Japan and they have been keeping it very close to their chest, so my contacts at Yamato Hong Kong know nothing about it.
Also, unfortunately my main contact at Yamato Japan is no longer directly involved in the day-to-day management of the Macross line, so my access to info is not as good as it used to be. I'm not that close to the guy now in charge of Macross product development
Anyway, I'll probably buy one of these whenever they come out. If it turns out to be good then I may buy 3 to 4 more. However, at the moment I'm really satisfied with the acrylic rod display stands I bought from s i t h l o r d.
