Critics exploited the accident to undermine the IK-1 concept, with Bajdak joining those criticising the aircraft. The three flights were not considered sufficient to give a verdict on the design, and the debate over its future was fierce. This placed significant pressure on the designers, as every element of the aircraft design was subsequently attacked. Eventually, it was generally agreed that the aircraft was well-designed, but it needed more testing. At this point, Ikarus decided to build a second prototype, as it was evident that the hand-sewn fabric seam on the wing had not stood up to the strain of aerobatics, and their workmanship was in question. The second prototype took 10 months to build, with the two designers closely involved.
