From Aviation magazine 1977,so weird;
Already, in 1938, the Leo-48 represented a technical attempt
interesting to offer, to the field of maneuverability of the planes
of cembat, new dimensions. This device had little
time to confirm the speculations of its promoters, But had
you deserve to draw attention to a new formula that sees
currently day. The span was 11.30 m, the length of
8.77 m and the height of 5.57 m, this height being explained by
the vertical surface located forward of the center of gravity. This
surface was 2 m2 above and 1 m° below the fuselage. The canopy itself had an area of 17 m2. With two 140 hp Régnier 4 GO engines, an empty weight of 1,600 kg and a total mass, with three occupants, of 2,100" to the aircraft
should have a maximum speed of around 300 km/h.
