Intended as an advanced military trainer, the Gabardini was a conventionally laid out two bay biplane, its thin section, unstaggered wings braced together with a near-parallel pair of interplane struts on each side and assisted by flying wires.
The biplane's empennage was also similar to that of the monoplane, with its tailplane well forward of the rounded, single piece rudder and mounting a pair of semi-circular elevators.
Though the biplane had a skidless conventional undercarriage, with single mainwheels strut-mounted and wire braced to the lower fuselage near the wing leading edge, the tail skid was unusually long and attached at mid-fuselage just aft of the cockpit.
On the ground the aircraft had an attitude closer than usual to that attained in-flight, keeping the elevators, which when deflected reached below the fuselage bottom, well clear of the grass.
Apart from the effect of different engine diameters, these variants were similar in appearance, though at least one of the higher powered Le Rhone aircraft had a rudder which was less upright and also scallop-edged.
