The Roma was designed by Angelo Mori and built by the
Grupo Volo a Vela Tommaso Dal Molin () in
Varese. It was a
cantilever high-wing monoplane, its high
aspect ratio, single
spar wing constructed with a wooden frame and covered in
plywood and
fabric. It was mounted with some
dihedral and in plan was straight tapered with elliptical tips.
Ailerons occupied about half the span. The
fuselage of the Roma was flat sided aft of the wing, which sat on top of it. Between the
trailing edge and close to the tail it was fabric covered; the rest, like the forward fuselage, was skinned with ply. All the fuselage surfaces were treated with ship's waterproof paint. The cantilever horizontal tail, mounted on the
fin just above the fuselage, was slightly straight tapered. The fin was very small, serving only to mount a large, slightly curved,
balanced rudder. This extended below the fuselage, moving within an
elevator cut-out and partly protected by a ventral fin. The
cockpit was immediately ahead of the wing
leading edge, with a curved upper fuselage reaching forwards to the nose. Different cockpit enclosures were used, though the order is uncertain. One placed the pilot under a separable, multi framed
canopy; with the other the pilot after entry was surrounded by a demountable ply covering which filled the larger aperture, allowing his head to emerge from within an open, circular, collared hole. The interior was lit by glazing in the cover just in front of the seat. The Roma was an
amphibian and had a single step,
flying boat style hull with the step under mid-
chord. Small stabilizing floats were mounted under the wings at about two-thirds span, each attached by two spanwise parallel pairs of V-
struts. Land operation used a standard glider skid, running from just aft of the nose to aft of the trailing edge. A
dolly was used for launches. ==Operational history==
