Lol I am a complete amateur in the field. What I do know about the subject is just stuff I've been reading online, some of which admittedly are legitimate academic sources.
My thoughts from another forum:
I just came to another realization on why the top of the radar dome appears "flatter" for the lack of a better word, than those of other fifth generation fighter aircraft. My guess is that it is to provide a wider field of view for the optical sensor.
J-10 uses WS-10 and those technically produce black smoke too, except it produces it in fairly short bursts so it is not visible. Technically even the mighty F-119 produces black smoke under certain conditions, so there is that.
You can put lipstick on a pig, but... All I can say is that Baidu is foolish for trying to boost their stock valuation with this before the thing is ready.
There are two articles from the Second To None magazine that covers the J-10C’s capabilities pretty well. Engine has traditionally been a weakness of Chinese aircraft but Pakistanis pilots who have flown F-16s are impressed with the thrust and responsiveness, which is very telling. That is...
Turns out I was wrong. The phones are in a display case next to backpack, family photos, a spoon, diary, and rifle magazines. Also, this specific model appears to be a Xiaomi, not Oppo/Vivo.
Said RCS is for a narrow cone in frontal aspect (+-20 degrees from the nose cone) only. This is why fifth gen fighter pilots are trained so that they only present they smallest RCS to enemy assets. Only when sixth gen fighters are introduced will there be true all aspect stealth.
