FS2004 Vintage Flying Boat Savoia Marchetti SM55X by Massimo Taccoli with a Modified panel bt Luke Califati, featuring pre-WWII Italian metric gauges, sounds from another twin-row radial.
The SM55x was a double body flying boat with two twin-row 18 cylinders radial engines mounted in-line high over the cockpit in a pusher-puller configuration. The SM55X was not particularly fast, or maneuvrable, or fuel effective, or anything. But it surely was one beautiful airplane.
In 1933 Italy's Ministry of the Air, Gen. I. Balbo flew the plane depicted in this model from Italy to Iceland, Canada the U.S. and back home leading a fleet of 26 SM55X planes, the flight was sponsored by the Italian Air Force to celebrate it's first 10 years of existence.
