China's J-20 stealth fighter was a disappointment at the 2018 edition of the country's annual air show in Zhuhai in southern China.

Three of the twin-engine warplanes put on what one reporter called a " conservative" aerial display lacking quick turns and other high-energy maneuvers.

Likewise, it was apparent that the J-20s at Zhuhai didn't feature the latest, Chinese-made WS-15 engine, and instead were still flying with older, Russian-made AL-31 engines.
