Anigrand Craftswork - 1/144 Piasecki YH-16 Transporter. World largest helicopter in 1950s. Includes bonus kits of the Kaman HH-43B Huskie, McDonnell XV-1 Convertiplane and Doak VZ-4DA. In 1946, the U.S. Army Air Corp issued an requirement for a wide-ranging helicopter capable of rescuing downed strategic bomber crews. The aircraft also had military application as a large troop and cargo transport. Piasecki submitted the Model PV-15, and was awarded a contract for the development of two prototypes, designated YH-16 Transporter. The first prototype was powered by two Pratt & Whitney piston engines and made its first flight in 1953. During construction the second prototype was modified to Model PV-45 standard through the replacement of its piston engines with two Allison turboshafts. The change in power-plants prompted a redesignation to XH-27, though this was changed to YH-16A prior to the aircraft's first flight in 1955. Both transporter variants were at times fitted with varying types of experimental horizontal tail surfaces, but none of these designs were adopted for permanent use. The YH-16A became the worlds first twin turbine helicopter and established an unofficial speed record of 166 mph. In 1956, the crash of the second prototype led to the cancellation of the YH-16 program.
