1:72 Scale Diecast metal and plastic parts – Boeing CH-47 Chinook - South Korean Army - 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.
