as am I, I will note that I recently ordered a 1/100 th scale model of the J-20 and PAK-FA,,,,,, I am happy to report the PAK-FA will turn well inside the J-20, although as you might have guessed the J-20 is stealthier and may carry more internal weapons? LOL, I do like observing the differences in the two models, the PAK-FA still remaining true to the Flanker traditions, and the J-20 with its distant coupled canard attempting to achieve the rapid pitch transitions necessary to "play games" with the big boys. I would say the PAK FA is still 3-5 years away from IOC.
