1:72 Scale Diecast metal and plastic parts ? Boeing CH-147, CH-147F Chinook - Canada - Royal Canadian Air Force - UN - 450 Tactical Helicopter Squadron, Camp Castor, Mali, West Africa 2018 - 2019 Length: 8.5" (fuselage) Rotor span: 10? This model is made of a combination of diecast metal and plastic. This Chinook model has two rotors, from the tip of the back rotor to the tip of the front rotor it measures 16.5 inches. A display stand is included. The blades for the main rotor need to be attached. Although they are supposed to be snap/friction fit, it seems that it will be better is a tiny (very tiny) drop of super glue is applied just to keep things secure. The assembly for the rotor and the blades are very fragile, so one needs to be very careful when attaching the blades since it is very easy to bend or break things out of shape. These helicopter models are really not toys, they are not made to be played with. They will not last long if played with. Moreover, these models are made to look realistic and faithful to the real thing, so little parts like landing gears, skies, weapons, pods and antennas are made from small parts and are very fragile. The rear access ramp can lower and raise. The inside of the model shows details such as benches and wall panels. The Boeing CH-47 Chinook is an American twin-engine, tandem rotor heavy-lift helicopter. Its primary roles are troop movement, artillery placement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external ventral cargo hooks. With a top speed of 170 knots (196 mph, 315 km/h) the helicopter was faster than contemporary 1960s utility helicopters and attack helicopters, and is still one of the fastest helicopters in the US inventory. The CH-47 is among the heaviest lifting Western helicopters. Its name is from the Native American Chinook people
