Unpowered sailplane — no engine
Post-war Czech high-performance glider with mid-mounted tapered wings
Single-seat enclosed cockpit with clean aerodynamic fuselage

A clean mid-wing sailplane with a graceful tapered wing, fully enclosed cockpit, and conventional tail; the smooth fuselage lines and absence of an engine are defining features.

History

Designed by František Kautský at Letov and first flown in 1948, the Luňák was intended to meet the demand for competitive gliders in post-war Czechoslovakia. It achieved respectable performance and was used by Czech soaring pilots in national and international competitions.

Variants

Limited production run; no major variants documented. The LF-107 designation follows Letov's post-war glider numbering sequence.

Where you'll see it

Used by Czech sporting and club pilots in the late 1940s and into the 1950s; a few may survive in preservation.
