In the following spring the Akar was used by the SL to look for good gliding sites in the Babia Góra. Equipped with skis, it made a flight on 3 April 1924 (another source gives the date as 8 April) which lasted 325 s, covered about and set a Polish record which stood for over four years. It crashed either at the end of this flight or in a later one. After the crash the glider was redesigned by Stanisław Prauss as the Akar II, with a rectangular section, ply-covered fuselage and a new empennage. It was entered for the Second Polish Polish Glider Contest of 1925, though it did not appear there. Though Cynk reports that the Akar II was built, another source claims that the students were blocked from using the University workshop and no rebuilding of the Akar occurred. Its remains were destroyed in the autumn of 1925.
