Helicopter US Army Boeing Ch-47C Chinook 12.5" Wood Model Aircraft The Boeing CH-47 Chinook is an American twin-engine, tandem rotor heavy-lift helicopter. The CH-47 is one of the few aircraft of that era that is still in production and front line service, with over 1,179 built to date. Its primary roles include troop movement, artillery emplacement and battlefield resupply.Improved and more powerful versions of the CH-47 have been developed since the helicopter entered service. This specific CH-47 model is the CH-47D, which was the US Army's first major design leap, which entered service in 1982. Improvements from the CH-47C included upgraded engines, composite rotor blades, a redesigned cockpit to reduce pilot workload, improved and redundant electrical systems, an advanced flight control system and improved avionics.This handcrafted model is painstakingly built from Philippine mahogany by our skilled craftsmen with a wealth of detail and makes a great gift for any veteran, aviation enthusiast or history buff.
