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.
[2] The Ikub I, essentially an unpowered but otherwise conventional parasol wing monoplane, gained the second prize.
Its one-piece, twin spar wing had a rectangular centre-section and tapered outwards and was covered overall with fabric.
[1][2] Its fuselage was a simple, rectangular section, ply-covered structure with a single-seat, open cockpit under the wing leading edge.
The Ikub had a fixed conventional undercarriage, with its wheels on a single axle mounted on short, steel tube V-struts.
