Just to put it out there, in case it wasnt clear. To OP, the kit you're building is not perfect transformation.
Note the battroid-mode nose cone has the hip joints while fighter-mode doesnt.
Basically there are two swappable front fuselate sections, one for fighter/gerwalk, another for battroid.
And yeah, Bandai's latest 1/72 VF-1 kit is a mess...but fun to build.
Wish they can revisit them, but given that other recent Bandai toy-valks are overly complicated to transform, I dont they have the know-how to simplify the transformation.
