The Wing Loong was commissioned by China's Air Force. Several red stars were painted on the fuselage of the drone to show how many missions it had flown.
AVIC also showed a model of a new generation fighter jet, the J-31, a stealth plane whose existence was revealed only recently.
The J-31 display featured only a one-quarter scale model of the jet, but it attracted big crowds. The PLA Daily website also posted pictures of the black aircraft model during the exhibition, but identified it only as an "advanced fighter concept."
China's first stealth fighter, the J-20, was unveiled in early 2011, but is not expected to enter service until 2018.
The J-10, the first supersonic 3rd-generation fighter jet designed and manufactured using Chinese technology, made its appearance on the final day of the show.
Pilots with the Bayi Aerobatic Team of the PLA Air Force performed elaborate formations with the multi-role combat fighter, which is capable of operating under all weather conditions.
"It looks very dangerous," said Huang Yi, a bystander from Guangzhou who was viewing the aerial stunts. "Two of the aircraft flew very close together, but then they flew off in opposite directions."
The Zhuhai air show was first held in 1996 under the name Airshow China.
It has become the biggest air show on the mainland and the only one supported by the government.
