Wow! That is gorgeous! I really like how you did the exhaust staining. Is your technique for that in one of the vids? (I can't watch them right now, but plan to before I start mine, for which I just received Hungarian markings). I like how it isn't one smooth swoosh of soot, but looks really realistic.
Your weathering on the whole plane is spot on, and it looks ready to taxi, take off and fly away.
Excellent job!
