There is a glaring error in the 1/350 Merit JFK kit which--if copied in any way--could result in a very undesireable product. The Merit 1/350 hull is stamped "Kittyhawk," while the flight deck is marked "JFK." This causes the two not to align, since the Kittyhawk and JFK flight decks are quite different. See this review:
It hasn't happened yet--and it may not even happen at all. Still, this is something to be "on alert for" once the 1/700 kit is released (whenever that may be.)
I like the review I read of the 1/350 Merit Kittyhawk, and will thus consider the upcoming 1/700 offering. Here's hoping Trumpeter doesn't mess up the JFK.
