How does China's manufacturing and logistics prowess manifest? Take my newly acquired J-20 1:72 scale model—not even at the lowest promotional price, yet it cost me less than $3 and was delivered right to my doorstep.
A very esoteric subject from Xiaohongshu -- China's first large flying testbed!
RA-76456, was transferred to the Gromov Flight Research Institute in 2004, where it had its radar dish and support structure removed from the back of the fuselage and was modified into an aerial engine testing platform, with its model designation changed to the IL-76LL type for such purposes. After modification, RA-76456 was quickly noticed to have been repainted in a red color different from that of Russian civilian aircraft, and the logo of the Chinese Flight Test Institute was painted on its tail.
In the same year, RA-76456 came to China and was delivered to the Flight Test Institute, retaining the 76456 number on its vertical stabilizer but without the preceding Russian nationality "RA". In the state of having its antenna feed pod removed, the 76456 number was also removed, and large-sized "760" numbers and Chinese characters such as "Chinese Flight Test Institute" were added on both sides of the nose.
The 760 aircraft completed a series of engine tests at the Flight Test Institute. In February 2015, footage of an Il-76 flying at the Flight Test Institute showed a new large bypass turbofan engine installed on the inner side of the left wing. This Il-76 carrying the new engine was first revealed in January 2014, and it was speculated that the new engine could be the domestically produced WS-20 engine for the large transport aircraft Y-20.
