The lower wing was predominantly an attachment for the wing struts; it was almost removed in the second series, the I-4Z (where the lower wings were greatly shortened), and totally removed from the I-4bis, thus transforming the aircraft from a sesquiplane into a parasol-wing monoplane.

El ala inferior era predominantemente un soporte para los parantes del ala; fue casi retirada en la segunda serie, con el I-4Z teniendo alas inferiores muy acortadas, siendo completamente retirada a partir del I-4bis y transformando al avión de un sesquiplano a un monoplano con ala parasol.
