Copy on the ebay item read: RAND ROBINSON KR-2On June 1, 1974, the KR-2, a two seat version emerged into the world of experimental aviation with its maiden flight. The prototype KR-2, N4KR, was powered by an 1834cc Revmaster, which is an otherwise stock 1600cc VW with 99mm cylinders. This particular engine was a single ignition version and used a Bendix mag and a Posa carburetor. Revmaster gives the engine a continuous rating of 60 hp at 3000 rpms, which is on the conservative side. Ken Rand, the designer/builder, obtained cruise speeds of 180mph at 3200 rpm and airspeeds of 200mph at higher altitudes. KR-2 Specifications Dann
