I've recently acquired my first yamato perfect transformation valkyrie (the somewhat recently reissued Skull Leader VF-1, with the optional parts) and I've had a small issue with the hip assembly.
The "T" shaped bar that is connected to the hip bar that plugs into the nosecone is what is causing me problems. Where this bar connects to the straight metal bar (located almost like a spine in battroid mode) wants to sag outward. When the hip assembly is plugged into the nosecone, at the joint where the two metal bars meet, it is forced outward as the whole figure slouches forward.
When the toy is standing, all that is preventing the hinge joint from rocking back and popping out of place is the trap door of the nosecone. And this door is permanently bluging outward, and any force on the hips that moves that joint is enough to have the trap door pop open, and the joint to fully sag outward (often disloding the hip bar clipped into place).
I am somewhat at a loss. I'm unsure if this is a common problem of the design, or if the inner section of the nosecone is supposed to grip the bar more tightly, preventing it from so easily disloding itself.
I apologize if my wording was confusing, and any information would be most appreciated.
