Well my stories aren't so happy. I had my first Yamato, my vf-1a Hikaru fell off a 6 foot bookshelf and the clip that holds the intake that attaches the leg to the fusalage of the fighter break off. now he can only be displayed in battaloid.
I also got my then 12 year old cousin the same valk for his Birthday (tried to get him hook, I failed, apperently pokemon have more appeal to kids back then then Macross valks did) well kids being kids, he managed to snap off both tailfins. but of my 12 valks, that's the only one that has taken a fall and or has ever had anything break.
