I gotta admit I don't see the benefit of training in an aircraft that is going handle differently than the mainline fighters Russia currently has on the books...

Article said no orders on the books yet. . .being pitched to Russia but not in service.

Read an article somewhere that one has been delivered to a private individual but the Russian af has no need as they just got a new trainer. This will be for export and indivuals who want to play top gun.
On 11 August 2014, Commander-in-chief of the Russian Air Forces, Colonel General Viktor Bondarev claimed that Russia is still continuing the research and development of Su-47 or similar forward-swept wing fighters. The new prototypes of such aircraft will be unveiled in the near future.
Pros and Cons:
Maneuverability
The Su-47 has extremely high agility at subsonic speeds, enabling the aircraft to alter its angle of attack and its flight path very quickly while retaining maneuverability in supersonic flight. The Su-47 has a maximum speed of Mach 1.6 at high altitudes and a 9g capability.
The swept-forward wing, compared to a swept-back wing of the same area, provides a number of advantages:
- higher lift-to-drag ratio
- better agility in dogfight situations
- higher range at subsonic speed
- improved stall resistance and anti-spin characteristics
- improved stability at high angles of attack
- a lower minimum flight speed
- a shorter take-off and landing distance
Wings
The forward-swept midwing gives the Su-47 its unconventional appearance. A substantial part of the lift generated by the forward-swept wing occurs at the inner portion of the wingspan. This inboard lift is not restricted by wingtip stall and the lift-induced wingtip vortex generation is thus reduced. The ailerons—the wing's control surfaces—remain effective at the highest angles of attack, and controllability of the aircraft is retained even in the event of airflow separating from the remainder of the wings' surface.
A downside of such a forward-swept wing design is that it geometrically produces wing twisting as it bends under load, resulting in greater stress on the wing than for a similar straight or aft-swept wing. This requires the wing be designed to twist as it bends—opposite to the geometric twisting. This is done by the use of composites wing skins laid-up to twist. The plane was initially limited to Mach 1.6.
