Pazmany PL-2:
Shortly after flight trial of the PL-1 began, Mr Pazmany initiated a complete Redesign of the aircraft. The developed design, known as the PL-2, is almost identical with the PL-1 in external configuration. Cockpit width is increased by 2 in and wing dihedral is increased from 3 degrees to 5 degrees. The internal structure is extensively changed to simplify construction and reduce weight. Suitable Lycoming power plants are the 108 hp O-235-C1, 125 hp O-290-G (ground power unit), 135 hp O-290-D2B or 150 hp O-320-A. Static tests of every major assembly up to ultimate loads had been made by early 1967. The first PL-2 to be completed was built by Mr. H. Pio of Ramona, California, and this aircraft made its first flight on 4 April 1969, piloted by Mr. Pio. It has an O-290-G engine. A single example of the PL-2 was built by the Vietnam Air Force, each VNAF base contributing towards its construction. This flew for the first time on 1 July 1971, and it was reported that production of at least ten more PL-2s for use at the VNAF Air Training Center was being considered. The Royal Thai Force was also known to have two PL-2s under construction; but no further news of this project had been received in early 1974. The Republic of Korea Air Force built one PL-2 prototype for flight testing, and has since completed three more for evaluation as trainers. In Japan, the Miyauchi Manufacturing Co Ltd, Tokyo, completed a prototype of the PL-2 in the Autumn of 1971, this being exhibited at the Nagoya International Air Show during October-November 1971. The Indonesian Air Force was building an example of the PL-2 at the Lipnur factory in early 1974, for evaluation as a military trainer. Tooling for limited initial production has been prepared.
