Pre-cut formers, wing ribs too, that need to be sanded and glued is a kit. Looking for a precise definition? You're not going to getg it, at least from me. It's like former US Attorney genral Ed Meese said about pornography: I can't define it, but I know it when I see it.

Same with kits and ARFs. And, like I said, just my thoughts, Nobody's forcing anyone to agree.
