It seems the files need some tweaking, because, as a test, I couldn't find F_80N in neither class.dcg, payloads.dcg or allpayloads.dcg
I suppose it would be the same for the other planes and chiefs and stationary planes

They are a little outdated. They are both complementary.
I recommend that you take a look at those. They may seem a little overhwelming at first, but I can asure you, they aren't as hard as they seem at first glance. And anyways, you can always ask here.
Basically, some entries for some planes, weapons, chiefs and stationary objects are missing. You just need to add them and you are done.
