I have finally opend up the first three 1/48 VF-1s and transformed them and I have a few questions.When moving the arms into part of the GERWALK mode there were "tabs" under each arm where the shoulder part unfolds. I tried to lock the arms down when transforming the valkyrie back to fighter mode However i was not able to. Are the arms suppsed to lay flat when in fighter mode? Or are the pieces that connect the shoulders supposed to be at an angle? I had also checked the other valkyries and the arms are the same. Is there a purpose for those tabs? Does anyone have any information? Any information would be greatly appreciated. Thanks in advance.
