Thank you for your friendly feedback. They are not competitive models as thy last works are not far from comparable. For my collection of GCE just like me.
What are the models? When I-152 you were right, they are both ICM and I have to say to them worked quite well.
At I-15, but you're wrong. I started to build Azur (Republican machine built) and I found that it has a number of errors. I was especially angry upon careful work with resin engine when I almost did not get to the body. Resin accessories are in fact smaller diameter than they should be and when you add the engine and exhaust, it's almost a disaster (or should pray that something did not crack when you give it forcibly together ...). So I was in April, visiting one competition in the Czech Republic, turned into a product ICM (they make the I-15!). I was glad that I was the second model I-15 has not yet started to build. And practice I-15 Spanish provenance (Sabadell 1941) I built from kits ICM. And I recommend it to everyone, just watch out for soft plastic.
