This kit is in 1/700 scale. It includes 6x SA 321 Super Frelon or Chinese Z-8 Helicopters. They are connected as a single sprue by a wire under the main body of the aircraft.
According to Wikipedia: "China acquired 13 Super Frelon SA321 naval helicopters in 1977-78. These helicopters came in two variants: anti-submarine warfare (ASW) and search and rescue (SAR) versions. The Super Frelon was the first helicopter of the PLA to be capable of operating from the flight deck of surface vessels. China also produces the Super Frelon locally under the designation Z-8 (land or ship based ASW/SAR helicopter). The Super Frelon remains operational with the PLA Navy in 2014."
