PLAAF open admission that J-11BS copy of SU-27SK are unreliable and inferior.
despite the aircraft include more composite material, but load still unable to match SU-27SK
the J-11BS that power by WS-10,rarely fly supersonic, reason, WS10 unrelaible, mechanical problem....etc.
problem also incle metallurgy..
no wonder. China seeking to purchase SU-35
one area, is the avionic.the paper supeior to SU-27SK.
If the J-11B was that disfunctional as the article claims then would the PLAAF have ordered so many of them. And went ahead and created 4 more derivative of it, the J-11BS, J-15, J15S and the J-16.
