Hi, I pretty new to Iron factory. I want to collects them. But Just find out that the early model did not have the hip joins. The joint like in this picture, between the hip and the belly and help the figure can crouch their abs like this So if they don't have this joint. Which mean they can only rotate the belly ? Can anyone tell me from which model, they start to have hip joint ? Also, I see the ex 11 evil lord can bend down thank to the joint between the belly and the chest. Can ex 14 optimus do the same ? I planing to get him, or any color of the 14 mold. But as a early model, I don't know if he still hold up ? I see the review clips and saw him have a joint in the chest, but it is a part of the transformation, And seem like it only help him bend up, not down. And, Do you think there is any aspect i need to aware about Iron factory figure, please let me know ! thank.
