Hello Troy:
It?s an UTI,as the Yak-7V?s had fixed landing gears and no weapons.All the planes marked as "UTI" are armed trainers.The Yak in the picture could be also a Yak-7a single seater converted into a 2 seater.
Overall aluminum dope with plain red starts?
I agree,the surface is too shiny to be painted in white o light grey.As for the interior colours,I don?t know,sorry.
Regarding the ICM kit,I started one but never finished it.It?s a simple kit which has a pretty detailed interior but lacks many external details as the radiator faces.As usual with ICM kits,the fit of parts is not good.It you want to make an accurate representation of the Yak,you should make the fuel dials over the wings.In the interior,the seats backrests need to be thinned as they are too thick.Hope to be of help.
Greetings.
Martin
