Italeri is a hit and miss company when it comes to kits.
Pure Italeri kits that originated with Italeri made molds are generaly good and go together with few problems.
The problem is that Italeri often issues kits from other manufacturers, usually Testors or Esci originated molds and you really have to do your research to figure out where your "Italeri" kit is coming from in origins.
When Socialism came to an end in the early 1990's, Italeri boxed up a few kits from Eastern manufacturers, most notably Bilek from the Czech Republic and Zvezda from Russia. Italeri did make a point of marking on the box what the origins of those kits were. Bilek is good stuff if you have some previous building experince under you belt, I built a Zvezda kit once and you couldn't get me to build another if you held me at gun point.
Like I said, do your reaserch, kit reviews can help a lot as can a hobby shop with a suitably knowledgable staff. My experience with italeri goes like this:
1/72 T-45 Goshawk (very nice kit)
1/72 Panavia Tornado (also very nice)
1/72 NATO F-16 A/B (old Esci molds, not up to today's standards)
1/72 C-119 Flying Boxcar (a classic, good kit but needs an experienced modeller to do it justice.
1/72 SU-22 Fitter (from Bilek molds, generally nice kit with few problems)
1/72 F/A-18 Hornet (questionable engineering in places, more complicated than it needs to be)
1/72 Harrier GR.5 (a decent kit that I have no complaints about)
1/72 Antonov AN-2 Colt (another from Bilek molds, don't try this without significant modeling experience, its good, but complex)
1/48 F/A-18 Hornet (I think this one bounces back and forth between the Italeri and Testors labels, its workable, but you can find better)
Well, thats my Italeri experience, I hope its helpful to you. Pure Italeri kits can be a joy, just do you homework before shelling out for a kit from them.
I've heard that Italeri's new 1/72 F-8 Crusader is just a reboxing of older Hasegawa moldings, can anyone confirm this for me?
