Marske Aircraft
Marske Aircraft Corporation is an American aircraft design firm founded by Jim Marske and based in Marion, Ohio. The company specializes in the design of tailless gliders primarily for amateur construction.
Marske's first design was the Marske XM-1, constructed in 1957 when he was 19 years old. The design was an experiment and only one was constructed. The Marske Pioneer series first flew in 1968 and has been developed through the all-composite construction Pioneer III model. The Marske Monarch is a tailless ultralight glider that was first flown in 1974, during the early heyday of hang glider flying. The Monarch can be built as a powered self-launching sailplane or as a pure glider, depending on whether an engine is installed.
Marske also collaborated with US aerodynamicist John Roncz in 1992 on the design of the LAK Genesis 2 that was produced for a time in Lithuania, 27 having been completed. The Genesis was the first production aircraft to use Graphlite carbon rods for the spars.
