In this price I would expect more stuff inside like string,brass tubes for rigging and some resin details.There are similar kits in 1/72 like AZ Avro 621 Tutor and Special Hobby Polikarpov R-Z which cost half the price almost.
I predict that the kit will sell a lot and the price was set so high on purpose because many people will choose Azur instead from Grand Models resit kit which is nice also.
Anyway it looks a very nice kit.
