Kit #AA2008. 1/72 scale. Highly-detailed resin kit with decals. The Doak Model 16 was the world's first aircraft to demonstrate the tilting duct VTOL concept. In 1956, the concept interested the U.S. Army, who bought a prototype, designated VZ-4DA. The configuration had a tilting duct blower located at each wing tip, pointing vertical for take off & landing, and rotated to the horizontal for forward flight. Engine exhaust was deflected at the fuselage rear for pitch control. To limit the development costs, the prototype "recycled" many parts from existing airframes, including the landing gear from the Cessna 182, seats from the F-51, duct actuators from T-33 electric flap motors, and the rudder mechanism from other Doak aircraft. The first flight was performed in 1958. After a year of tests, the U.S. Army accepted the VZ-4 and passed it to NASA for further tests. In 1961, Doak ended his business and sold all the patent rights and engineering files to Douglas Aircraft. Although Douglas had ideas to improve the VZ-4, the Army decided it was no longer interested in the concept. The prototype VZ-4 remained with NASA until 1972, when it was transferred to the US Army Transportation Command Museum. Limited quantities available from remaining Anigrand stock!
