Academy B-24 question

I’ve heard that there is a problem with the kit’s wing when built straight from the box. Is this correct and if so what is the fix?
Thanks,
Eric

Somebody once told me that there’s a warpage problem that’s hard to correct. Cannot say if this is true of all the Academy B-24 kits or just certain ones made during a specific period of time. I dry-fitted mine (I have a -D and a -J) and saw very little problems with fit.
