As with several AV400 releases the wait from announcement to release has not been short but multiple 77Ws of AV400 are now on the market.
The newest contender is from Aviation400, who are swiftly making a name for detail and quality with their A350s and A330MRTTs. Accordingly, competition for sales is intense and there have been two new moulds for the type in the past 3 years. Although the 777-300ER is swiftly approaching the end of its production it is still a major player in both the long-haul travel market, of 1:1 aviation, and the diecast collector market, of 1:400 scale.
