I found it quite amusing it was revealed (well, guards letting people pull out their mobile phone to make pictures) shortly before Gates' visit to China, and flown on the second day of his visit. I didn't hear about the Guam statement, but not surprising. Reason behind it all, US weapon deliveries to Taiwan gotta stop in their eyes. But politics aside.
I should look at it more closely, redesigns because of flutter are not uncommon, you could be right.
It doesn't look difficult to model, I don't think you have to wait long for someone to do a R/C model.
It has the AL-31Fs, with potentially getting the 117S/AL-41F. With the Flankers doing Mach 2.4 - 2.2, this is looking a tad heavier but sleeker, I'd guess you're looking at Mach 2.0.
It was first flight, right... I've never seen an impressive take-off for first flight. Also, did it use afterburners? If it didn't then, it's no wonder it didn't impress. I haven't seen the take-off yet.
Landing seemed really high speed though. But that may have been the video... framerates.
It reminds me most of the MiG-31 actually. Looks like an interceptor foremost.. Strike fighter, possibly, it should have a good bay. But mind you, that might as well be used for very long range missile, which are huge. The design doesn't say bomb truck to me.
