MarkD asked a very simple question. Instead of answering him, you clogged up this thread with a bunch of boring and useless trivia that have absolutely nothing to do with the original question. Let me summarize how ridiculous and ludicrous your post was:
MarkD asks, "Is there any visual difference between J-10B and J-10C?"
xyqq replies, "J-10 uses afterburner during takeoff and the leading-edge slats are not deployed, but it doesn't use afterburner during landing."
Seriously, what in the world are you doing? Please stop clogging this thread with your endlessly boring trivia, accompanied by images most everybody can access on their own. Try to at least make an effort to be relevant with your posts.
P.S. For those of you who are wondering where xyqq gets his images from, you can access them

, and
without his mind-numbingly pedantic trivia.
