Jilles Smits has produced yet another superb plan. Genesis 2 at 1/3 scale is a very interesting sailplane that looks great and performs extremely well. Very stable in flight. Designed to take two retract units and capable of being built with lots of scale features. The kit is of a fully built-up structure (All wood). A glass fibre fuss will be available in the future.

LAK Genesis 2 1/3 scale shortkit and plan from Jilles Smitts

Genesis 2

is a Standard Class competition sailplane/glider that was designed by an American team led by

Jerry Mercer, Jim Marske and John Roncz.

It was produced in Lithuania. It is notable in having almost no rear fuselage. However, it is not tailless, because it has a small, all-moving tailplane on top of the vertical stabilizer. The tailplane is mainly a trimmer, rather than for longitudinal stability.


During development, it was found that carbon rods formed by the “pultrusion” process could be used to provide a stronger spar. This technique has subsequently been applied to other LAK aircraft. The nosewheel was also made retractable and the wing washout was reduced. The production aircraft with these modifications, which flew in 1998, was called “Genesis 2”. There was a breakdown in relations between the American design group and the manufacturers, and so production was stopped after 27 had been made.
