Hi everyone. 
I just purchased a mint YF-19 Yamato toy. As I can see, it is an early version with the dreaded plastic tab at the front of "tab B", so I need to be extremely careful during transformation.  
I'm planning on keeping it in fighter mode, but I'm currently having difficulties transforming it. As a matter of fact, when I try to slide the little red tabs under the hips, stress makes tab B pop open, threatening to break the dreaded plastic thingie (see picture).  
Aaaargh!  No no no, don't break, little tab, please !    
On the other hand, if I unlock tab B before I slide the red tabs in place, the wing tabs just won't fit in their holes (they're several millimeters too high). 
It really looks like the hip pivot is quite a bit too low to allow the whole toy to snap into place (see second picture, which shows the toy sitting on its back). 
Any advice? 
Maybe I should just put the toy back in the box and cherish it at a safe distance?
