The VBŠ Kuňkadlo is a Czechoslovak light single-seat sports airplane built by the brothers Vladimír and Bohuslav Šimůnková between 1924 to 1926. Problems identified after the first flight led to an extensive redesign and eventually a successful plane that performed at air shows throughout the country. After WWII it was donated to the Národní technické muzeum in Prague where it is now on display.
