I had started the A320 on a clean bench, only kit on bench. I usually like to have two kits on bench, so I can work on second one while I wait for paint or glue to dry on first. I started the Hasagawa Embraer E170 that I had recently received. What a marvelous kit!
It has the centerline antenna molded as part of the fuselage, a feature I do not like, and had pinged Revell for doing that on the A320. But in the case of the Embraer it will not be important. The fuselage sides fit together perfectly! I don't have any paint or primer on it, but I cannot feel or see any offset along the fuselage center seam, and cleanup will be absolutely minimal. If any offset is there, it must be a fraction of a mil, and the seam fit is very tight! Lots of finely molded detail too!
