Sheva's Mini-Review primarily on the new arms......The instruction sheet. In English and Japanese (behind)
Comments/Points [compared to the older HotAngel (Machiko/ERT/SF arms/body)]1) Two point elbow articulation reduced to 1 that allows 100 degrees
(Picture A),
no big lost, most human can go to around 130 at most.
2) (Picture C) actually the arms can raise beyond 90 degrees, but you may put a bit of stress in the rubber covering the shoulders. The rubber covering is the thing that impedes it arms from going higher, push too hard you might tear it.
3) I believe there is a
lost of the mid-upper arm break (between shoulder & elbow), that allows the arms to twist outward and inward (Related to Warning pic 2nd from left and [4] below)
4) Improved shoulder ball joint that allows more free shoulder movement but opens some gaps on the shoulder holes of the rubber body. The arms twist at 45 degrees (as stated) is solely based on the ball socket attached to the body
(unless someone can proof otherwise). Maybe restoring say 50 degrees twist to mid-upper arm break (as in [3]) would not be too stressful on the rubber arms.
5) The rubber body mould appears to be the same as other HotAngel bodies.... (no thinner rubber at neck and such)
