I've written about HYJLwings A321s a few times. See:
Plus a couple have had the full review treatment by me at Diecast Flier:
Creating airline alliance colour schemes no doubt means that it is easier to create the artwork for the models and so it makes good sense to slip out a batch of similar but different models at the same time, especially when build totals are so small. In fact for the majority of these models the production runs are limited to 60 units each.
As per usual purchasing these models can be tricky however they are available on taobao and I believe through some shops in Europe (AMS I think) and probably also Threshold in Canada.
As I have previously said the HYJLwings A321 is an excellent model and it has been reviewed twice by myself at Diecast Flier. See:
For the Star Alliance HYJLwings produces Lufthansa, Air Canada and Eva Air examples:
For Skyteam there are 7 releases. Three are essentially identical China Southern A321s, two are old colours China Eastern, another is new colours China Eastern with the lone westerner being Air France:
These look like another batch of excellent models. For me only the Chinese ones are of real interest however I suspect it is the Western examples that will help improve HYJLwings profile outside of the East.
