I agree waynos, i am now doubting if the guy can even read.
chinawhite, do you think the J-10 would have existed if there was no LAVI ?
And i see that the guy has no problem saying every piece of nonsense on the LCA's slow and painful development, without looking at the J-10.
The J-10 infact was plagued by even more sivere problems....heck there were crashes of a prototypes...FBW problems...and what not....and was marred
by over 20+ years of painful plague like periods.
And all this despite the fact that it is essentially an alredy designed and built LAVI that is tweaked here and there with Russian help.
in mid-1996 - but suffered from an engine malfunction with unknown consequences. In late 1997 the second flying J-10 "1002" prototype was lost in a
crash which also killed the chief test pilot.

And the LAVI was Israel's attempt to build a plane that would match the F-16, but was cancelled because they were convinced that it could never do so
(even if it did have some minor modifications). Heck the Israeli's spent 2 billion $ on this and then cancelled it, because it was just not good
enough.
Now that raises serious doubts about the J-10 being able to "smoke" F-16's as chinawhite claims.
And chinawhite here are some links if you still believe that Israel had nothing to do with the J-10.
China and Israel started collaboration in the early 1980's and full-scale cooperation was underway officially by 1984. After the 1987 cancellation of
the Lavi, it was taken over by CAIC and the IAI carried on with the development of avionic equipment.
It is reported that the J-10's radar and fire-control system is the Chinese version of the Israeli-made ELM-2021 system
Chinese engineers are trying to develop the J-10 from a single F-16 provided by Pakistan, and with assistance from Israeli engineers associated with
Israel’s US-financed Lavi fighter program, which was cancelled in 1987.

David Lari, director general of Israel's Ministry of Defense, acknowledged in an Associated Press interview that "some technology on aircraft"
had been sold to China and that some Israeli companies may not have "clean hands".
The J-10's radar and fire-control system is the chinese version of the Israeli-made ELM-2021 system, which can simultaneously track six air targets
and lock on to the four most threatening targets for destruction.
the US Office of Naval Intelligence in its unclassified "Worldwide Challenges to Naval Strike Warfare" restated more strongly than it had the
previous year its belief that technology from the canceled Israeli Lavi fighter was being used on China's new J-10 fighter. It said, "The design
has been undertaken with substantial direct external assistance, primarily from Israel and Russia
In fact, according to the annual intelligence report, "the J-10 is a single-seat, light multi-role fighter based heavily on the canceled Israeli Lavi
program".

In the late 1980s, at least 20 engineers from Israel Aircraft Industries (IAI) were part of the fighter's design team at Chengdu."
"IAI also helped with windtunnel testing in the early design stage. The Israeli presence has been scaled down in the last three years"
"The Israeli design and development input in the programme is valued at more than $500 million. Overall programme costs are said to top $5 billion"

And i wont be surprised if Israel themselves are responsible for the changes on the J-10 from the Lavi, considering the level of Israel-China defence
co-operation in the 1990's and onwards (like sale of Harpy's, C4I technology, THEL, Phtyon 3&4 missile technology, etc)
