Like most 1930s primary gliders, the Basettino was a simple, high braced wing aircraft with a forward nacelle and an open frame rear fuselage.
The wings were supported over the nacelle by a single, central N form strut, with an upright forward member and a sloping rear component.
The latter defined the aft end of the nacelle and extended above the wing to form a flat, triangular pylon, from which a pair of landing wires ran to both spars on each side.
Flying wires from a point on the lower nacelle directly beneath the tip of the pylon ran to the same positions on the wing underside.
Two pairs of V-shaped steel tube struts were attached to it at the wing trailing edge and at its foot; the first was horizontal, the other upward sloping, and their rear meeting points were used to support the fabric covered empennage.
