Why they don't pull up the landing gears even at high attitude?
I suppose for safety during trails, just in case of engine failure or landing gear failure, they can still attempt a glide land.

Let's stick to reality instead of conjuring up scenarios, shall we?
Yes, I can assure you that from this side of the pond, there are many who are concerned about our own defense as well, and while no one desires to return to the cold war, I think mutual strength and respect is a good place for all the players to be. I can assure you that the American people value the relationships that we have with other leaders in the world. As a pilot and defense enthusiast, I am pleased, but slightly amused to see the Chengdo daily/weekly airshow starring the J-20. I honestly think this bode well for Sino-American relationships, as much of what we do is defense marketing, its interesting to see the J-20 being actively shown and marketed.
The ubiquitous preposterousness aside, I, a Chinese living in China, think such accelerated development process of the J-20 and the to-be-revealed domestic aircraftcarriers is necessary. And the six-or-more-J-20-protorypes rumor is believable.
I'm glad to know you know North Carolina and I have often thought I would love to visit the far east again. We had a Cessna 172 and if you get back over my little brother still has his license current, maybe we could go flying or a least have a good steak, well I better turn in before the boss wakes up and says what are you doing. Keep us up to date, and we have a an F-35 thread as well.
To clarify my position, I never claimed that multiple prototypes is not necessary, only that I do not think this would be the case this early on in the flight test program.

a good year by the Chengdu guys, and wish you a prosperous and successful new year

Thats right Letz, during initial test flights landing gear are often left down for the reasons you mentioned, plus aircraft have more drag, which serves as a crude speed brake.
