I'm not sure I understand what you mean about how loose Springer's transformations are though. You find him floppy?
I'm having trouble keeping his arms in in helicopter mode. I attached the tabs correctly, but it seems like a flimsy job. The back flap won't stay in its tab either. The car mode the shoulders/hood doesn't attach too well. It doesn't look correct. The sword attachment inhibits the vehicle movement. For either mode, I find I have to remove his head to transform him.
Nowhere in your incoherent ramblings did you come anywhere close to the answer. Thanks to you, everyone in this room is now stupider having heard you. I award you no points and may God have mercy on your soul. -Billy Madison-
