This American tandem rotor, heavy-lift helicopter was first used during the Vietnam War. Powered by two 4,733 horsepower turbo-shaft engines, it has a top speed of 196 mph which made it faster than any other utility and attack helicopter at that time. It remains in production and frontline service, with over 1,200 built to date. It starts as 2 4-inch square steel sheets and finishes as a 7.4″ x 3.74″ x 1.89″ 3D model. Simply use the easy-to-follow instructions included with the sheet to pop out the pieces, bend the tabs, and connect them at the attachment points. No glue or solder required.
