I think my color scheme was more unique - it is QR code

This scheme practically begged for my little addition.

Is that an alien from Space Invaders on the right side???????

I'd indicated I doctored it.  I saw the pixelated scheme and that's the first thing that popped in my head to do.  (I blame growing up in the early days of video games.  ;D )

He was my North, my South, my East and West,
My working week and my Sunday rest,
My noon, my midnight, my talk, my song;
I thought that love would last forever; I was wrong.

For nothing now can ever come to any good.

Certain modifications had to be done while both were in production after testing of earlier frames. Since -11 was earlier in production flow it just received the modified parts while -10 had to be reworked, hence taking longer.

I've read the September 2017 Air International article on the Su-57, and the electro-optical systems of the aircraft strike me as odd and rather redundant. The missile warning systems appear to be UV-based, which is optimal at detecting a burning rocket motor, but considerably less effective when the missile is coasting. Meanwhile, there are (at least) three separate IR sensors: the IRST located by the canopy, landing/navigation FLIR camera on one of the SRAAM bay fairings, and a targeting pod. I can't help but feel that there's quite a bit of redundancy there and that that something like the F-35's EOTS could've served all those functionalities.

After rumours earlier in the day about the first flight on one of the Su-57 prototypes of the new Izd-30 engine, pictures and videos have emerged on the web of the Su-57 flying with what appears to be a shorter engine/nozzle with that new recently seen serrated nozzle.

recently seen serrated nozzle has nothing to do with Izd.30

According to Google Translate, the T-50 design incorporates "innovative digital stuffing". That'll get you fired from NBC these days.

I believe it's because they are all developments of existing systems rather than a brand new design. Cheaper and easier but less capable.

Do you have a single piece of evidence suggesting any of them is a development of an existing system, let alone all of them? What system is the predecessor of KS-U? Or KS-O? For example Su-35S uses an IR-based system for MAWS and it looks totally different.
