03/31/2008. Remarks by Walter van Tilborg: "The X-1 (or PKX-1) is a two-seater with a 180 hp Franklin 60440-C4 engine. Rotor diameter 30 ft
4.56 in (9.26 m), length 25 ft 7.09 in (7.80 m), and height 8 ft 3.61 in (2.53 m). It was built mainly to test a collective and cyclic pitch rotor system that was patented in 1956. It was first flown in May 1956, and is now preserved at the Norwegian Air Force Museum at Cardmoen AFB, Norway. The Kjolseth X-1 and X-2 were the first, and so far, only indigenous helicopter designs in Norway. The aircraft were designed under leadership of Lt.Col. Paul Kjolseth of the RNorAF."
