The OVT is much more manueverable than the Su-37. The MiG-29 is smaller with a much more advanced TVC system. I don't know why everyone still holds
the Su-37 in such high regard. It's moves have been before in other fighters many times.
The MiG-29M OVT’s display demonstrates the aircraft’s ability to fly at very low speeds without angle of attack limitations, and to remain controllable in zero-speed and negative-speed (tail forward) areas of the envelope for sustained periods, where previous Russian fighters could only venture momentarily – for example during a tailslide or ‘kobra’ manoeuvre.
The new control system gives the pilot an unparalleled ability to point the aircraft (and thus his missile seekers) ‘off axis’, away from the direction of flight.
