Well Vishnu I'm no guru and I really want to see that video of yours. But having watched my own Aero India videos of the MKI again and again I have found that the flat spin comes immediately after a nose-up and a really small diameter loop - almost a Kulbit that makes the aircraft lose a lot of energy and all its forward velocity. When the aircraft is flat and not moving forward it starts descending. At this stage I have noticed that the canards are placed with one side up and the other side down - i.e they are both pointing in opposite directions.
Somehow the MKI seems to be so stable in that attitude that it starts losing altitude without tumbling - i.e. in that flat, upright position, and with the canards in "crosswise" positions as described above it appears that the plane begins a flat spin as it descends rather than an uncontrolled descent.
I don't know what is done then - perhaps the TV nozzles may be pointed down and thrust increased to put the plane into nose-down. The recovery from the flat spin always seems to be a nose down and acceleration into faster forward flight.
Just my guess. Did your flat spin come after a Kulbit/loop?
