Reports of the first German glider contest, held at the Wasserkuppe in the late summer of 1920, generated considerable interest in Poland, leading to the First Polish Glider Contest at Czarna Góra between 30 August and 13 September 1923. The contest was not a great success, limited by novice designers and pilots and a poor site, but the Karpiński SL.1 Akar was by far the most successful entrant.
