Just a bit of fun for you all :P I don't really know much about the I-15 to be honest, other than it was designed and built in the early 30s by the Soviet Union, back in a time when biplane fighters were still all the rave. It served the Republican air force during the Spanish Civil war in the late 30s, most of which in the conventional over-wing layout as opposed to the "Gull wing" format used by the Soviets. Sadly however, they were decimated on the ground and in the air at the beginning of WW2, and even the I-153 and I-16 fighters which replaced it were horrifically outmatched by modern German attack aircraft. They saw limited service during the war, and were somewhat second rate in comparison to modern aircraft like the up and coming Mig series of the time. All of that being said, I still do think it's a nice, hamster proportioned, comedic little plane with an interesting design and history. To fly this one, I'll be honest here, is unnecessarily hard. Taking off yaws it to the right constantly and has a habbit of nose diving even at moderate speeds. At around 165mph however, it does level out and becomes pretty stable. Enjoy! :D
