I never said anything but you are welcome to shut it if you like. The day you stop spewing diarrhea and have something factual and educational to say is the day you will earn respect.
What is "common knowledge"?
The fact is the SU-57 is quite superior to even the SU-35, that would hardly be a failure especially when it can hit its targets further, in some cases 3x further than the F-35/F-22.
You are a joke.
As for SU-57, it was never rejected, the Indians "haulted" the FGFA until the second stage engine is available. The FGFA and PAK-FA are two different projects.

Oh please, you are completely ignorant and clueless to anything aviation, much less the SU-57. Now go scoot along and stop pretend you know anything. The fact is, you can't discuss anything and look extremely pathetic by not having a single counter argument.
What "experts"? Almost everything about the SU-57 is classified. So those "experts" much like you are talking out of their rears. The few things publicly available about the SU-57 is that it has greater range, longer standoff weapons, 40,000lbs engines, high level of maneuverablity, AESA, OLS and probably side lobe radar for greater situational awareness and data-acquisition.
