On 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 carburettor. 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.
Some aircraft have not been built sufficiently lightweight and became in
effect single seaters.
A KR2 fitted with a Jabiru engine (lighter with more power)
has flown from the UK to Australia and back with 2 people.
