Monoplane variant of the I-4. Leading edge slats (half of the wing span) were controlled by the pilot. Engine cowling was replaced by Townend ring with individual fairings over cylinder heads.
I-4bis was rebuilt from series I-4 for research purposes and flown in 1931. It was 10km/h faster than production aircraft, but suffered some losses in maneuverability. Other parameters remained unchanged. Slats proved to be helpful, but manual operation required too much attention from a pilot. It was found that slats should be made automatic... and the concept was abandoned until 1940.
