A package can be double-boxed or triple boxed, but it doesn't matter if there is even just the smallest amount of space for the engine to shift in it's styrofoam cradle. I agree with some that it's really a packaging issue and not a shipping issue. If the engine is snug in it's packaging it should be able to withstand any amount of abuse (within reason) that it might endure while in the shipping process.
I like the detail that we enjoy on our models, but I've broken/bent parts just by not handling them correctly.
I can see both sides. You spent good money to receive an engine that should not have broken parts, but I think you would be best served to glue the parts yourself instead of waiting weeks to get it back from repair only to take a chance it will be broken again in shipping. Best of luck!
