It's a good thing I have not ordered anymore of the 1/72. They are a little small for display but good for being in a diorama.
But a 1/48 VF-25 will definitely be more than handful since it will be larger than Yamato's 1/48 VF-1 line.
I backed off the screws in the shoulders by about 1/3 of a turn each. That seemed to have reduced the rotational effort by half and still do well at holding up the arms with armor and gun. The screws can be tighten again if the joints starts to become sloppy. So for now, there is no problem to report.
I am surprised too at how clean, organized and efficient it is. If Toyota had operated a toy distribution center, it would probably look like that. It puts to shame a lot of the toy and hobby stores here in the US.
