FSX. Earlier this week the Project Tupolev released v1.2 of their highly popular Tu-154B2. Honestly, Russian aircraft are a breath of complicated fresh air and a very complex welcome change to the Boeing, MD, and Airbus aircraft we are all used to. I wish developers would get more into modeling Russian aircraft. It's actually funny, CaptainSim is a Russian team but focus solely on Western aircraft. How great would it be if they whipped out a Sukhoi Superjet, Tupolev Tu-204, Ilyushin Il-196, or even a Antonov AN226! In the mean time, get the Tupolev update!
