I've got the MRC 1/35th AH-1W kit of the prototype Whiskey Cobra that was released over 20 years ago (black paint job with the gold Cobra stripe down each side). So far, I remember test-fitting the kit, and gluing some parts together that didn't need paint first (stub wings, external weapons, etc), and don't recall any fit issues from the test-fitting. It's still sitting in my "To Do" pile, as are a few other kits...........
