  The development of aircraft held in parts difficult. Time was given, and the plane was quite difficult to manage. For example, first began development of fighter regiment in Tolmachevo (near Novosibirsk), they gave the "up" for four months. Nobody took into account the lack of SPARC in this type of aircraft.
