Okay, but how much lift does that create compared to a more classical high canard-low wing configuration? What are the pros and cons of same level as wing canard configuration, compared to the classical one?

Re: Fc-20 = J-10?
^^ J-20 is atleast 6-8 years from now and at the time, it would PLAAF which will induct the Stealth Fighter first. I think we can safely say that with JF-17 Thunders now in production, induction of F-16 Block-52s, the Mid-Life Upgrade of the F-16 Block-15s and the induction of FC-20 later on. That Pakistan Air Force has its hands full when it comes to fighters in its fleet. J-20 would be a large technology to absorb and it would take time and would also depend on whether China deems strategically necessary to sell Pakistan J-20s, vis-a-vis the enemy, 0india!

Just to add that the canard also serves the same function as the tail elevator to control pitch. The canards of the Su33 is too close to the wing for this function to be effective which explains its use of tail elevators.

this is the program for run test, the pilot must test this. why some body did'nt wait for it to be full airborn before taking the picture? they are fanboys, they like to take photos, why do they have to wait? they may not have chance to see fully airborn.

Wow, from 80 hrs of operation before overhaul, the article is now quoting 20 hrs. If this's really the case, it wouldn't even have passed design certification.
Are you saying that canards on su33 dont so much prevent the boundary layer over main wing to separate, thus increasing lift as they help increase the pitch of the plane quickly, over the short take off distance at relatively slow speeds, thus increasing the angle of attack of the wing more quickly and, as a result, creating the same amount of lift su27 would have (and not more lift) but creating it faster - over the short distance that is required on an aircraft carrier?
Piknov claims that the first maiden flight will be within few weeks and the engine is not Russia's 117 or AL31F.
平可夫：數周之內中國的觀眾可以看到J20試飛
KDR成都專電：漢和防務評論發言人平可夫今天（4日）對媒體表示：如果天氣一切正常、J20不出現臨時狀況的話，中國、世界的觀眾在數週之內就可以看到J20試飛。實際上已經處於倒數計時。
平可夫再次強調J20使用的是中國產改良型發動機。俄從來沒有向中國提供過117S!目前這種發動機不在出口中國範圍。T50試飛用發動機是117 而非117S！J20同時也不裝備AL31F或者AL31FN發動機。本刊對俄式發動機外形的記憶、了解勝過對自己心臟的了解。
關於117發動機，目前還在處於進一步的測試階段，並非完全定型。平可夫認為T50不可能在2013年裝備部隊。

No, not that. I'm not refuting the aerodynamic/streamlining function of the Su33's canard. I meant the Su33's canard would not be effective to control the pitch of the airplane thereby requiring the use of tail elevators.

On the question of canards, it is actually relatively simple to construct them out of radar-transparent materials (i.e. composites or carbon weave). Lightweight planes and gliders with rather long wingspans constructed fully of this type of materials can become invisible to most aviation radars (weather radars can catch them though) and must carry transponders to allow ATC to track them. While canards the size of the J-20's are clearly load-carrying structures, they're not normally equipped with components internally. A pair of fully composite canards completely transparent to radar is feasible provided China has the materials tech to pull this off. The same may be true of the rudders (ruddervators?) but rudders usually do carry electronics internally because they are normally part of the antenna array of the plane.
