I upload these files as a tribute to the late Igor Suprunov, who died a few months ago. He made a brillant simulation of the YAK-40. These instruction movies are made by Igor himself and are originally in Russian with an English "speak-over"; They are made for version 1.4 but besides the interface to call the different instrumentation panels, they will be still valid for the most recent version of his Yak-40. Igor himself lost this files when moving from one city to an other. I had some copies...
