How to Build a Mini LEGO Twin Rotor Helicopter

The Chinook CH-47 helicopter is a twin-rotor helicopter, and an interesting project to make, mini-sized out of Lego pieces. Mini models are generally in the 3 to 4-inch size range, and made of about 20 pieces or so. The helicopter uses a two-rotor system to keep the helicopter in the air and prevent it from spinning in the air. It's a very quick build, and a great addition to any fleet of mini vehicles.
