I don't know what they were doing with it? I find mine to be pretty sturdy. If you're looking for sturdy, have you checked out the JoyToy line?
JoyToy (terrible name, I know) has a SHIPLOAD of Warhammer 40k mecha and figures. They also have a vast array of mecha and figures too.
These are fully poseable^.
Joy Toy sounds too expensive and without the Gundam association.
