About a month ago, I managed to get my hands on a game called "DCS:Ka-50 Black Shark." Basically it's an uber realistic helicopter simulator, which has the entire cockpit navigation and control systems integrated right into it. This makes the gameplay quite complex, but also quite realistic at the same time.
The complex part is... well, the whole cockpit has about 70 to 80 switches and knobs. So even flying it can be quite a pain in the arse, but the toughest part for me so far is actually to get the helicopter up and running.
And today on my 5th try, I have finally managed to start the damn thing. Huzzah!
Note on the above video: I really wanna learn how to make that turn at 1:20.
