I learned early in modeling that AMT is crap. Their models are largely junk and their customer service is worse if you've got a problem even as simple as needing replacement parts.
The only kit I ever built that had their label on it that I liked was a 1/72 Fokker F-27 airliner and that wasn't even their kit, just a reissue of an older Esci kit.
I was overjoyed when AMT lost the Star Trek kit license and Monogram made the kits for the "Voyager" series and now Polar Lights are doing the "Enterprise" series of kits as well as some throw backs to the original series.
I could never get an AMT Star Trek kit to go together, but I've got Polar Lights' original series Enterprise waiting for me back home in Canada to start.
If you haven't guessed by now, I say give AMT a miss.
