Whats wrong with my skyhammer!?

I Finaly picked up DOTM Skyhammer. Everything checked out in bot' mode, But when the transformation began, I was shocked at just how many QC Issues this guy has! The chest piece under the rotor will NOT TURN! The little bits on his shoulders you move to reveal his head are very fragile, (Already forming stress marks) And his mech tech locking system is very fidgety, and it just is rotors wont go upwards anymore. it went up once, and won't go again. Is everyone else having at least one of these issues? Or is it just me? What say you?
