Five WZ-10 attack helicopters from the Fenglei (wind and thunder) aerobatic team presented a series of stunts at the four-day Second China Helicopter Expo, which opened in Tianjin on Thursday.

The two-seater helicopters flew in various formations and performed a host of sophisticated aerobatic maneuvers including flying backward and nose-diving.
