I re-read my post and I meant to say that colors on the real aircraft are all over the place.

You hit the nail to the head, Greg. This is a flying manual.
The dacals included in the kit only cover the most important markings but the quality is outstanding. I went for a full stencilling using the Begemot add-on sheet and as usual they are extremely thin (almost a bit too thin to bring the bigger ones on without a hassle) and finely printed.
It seems that fifty hours and more are always required for the decaling process of a Russian fighter.

I'm excited to read this, Greg. My next two projects: Yak-28 from Bobcat and MIG-25 from Kitty Hawk. It's going to be fun to push this together ...

Looks awesome!

Looking fabulous! Only "weathering" I can see in photos is some sun-mottling on the upper surfaces. I usually try to replicate this with some artist oils and mineral spirits. Sometimes it works better than others, and occasionally the final dull coat completely hides it...!

What brand of semi-matt did you use, or did you create your own mixture? I usually use flat (matt) due to scale (1/72), but for awhile tried using Testor semi-gloss so the detail would pop out more. However, I found the semi-gloss to be not a lot different than gloss, so stopped. The sheen you achieved on that Su fin looks perfect!

I think I would go with this semi-gloss. To me all the new camo looks more matt than glossy, no matter if they are NATO or Russian or whatever else.
Pure matt finish looks strange on this camo scheme, however.

I love this build. The artwork is fantastic and the technical skills are brilliant. Can you tell me about the jig that the Su sits on? Did you make that yourself? Can you show some photos of it - I'd really like to make one of my own.
