I thought I was the king of running Soviet birds after surviving the entire DoTM4 despite numerous big mistakes on my part but my attempt at being bigger and better with lessons learned failed miserably this time.
I will remain however a champion of unpopular aircraft and the smaller turboprops. Everything is supposed to work if you manage to employ it with careful planning under the right circumstances and to this point only the 9-seaters remain as symbols of absolute financial doom. I should know, I survived experimenting for several years with the PC-12 in MT7.
In short, be careful about expansion and make sure you can keep your LFs in the 70s and you should make it with the Russians. Also watch the range, the Tu-134 probably shouldn't go beyond 800NM these days.
