What was the advantage of the ducted fan?

More efficient thrust.  The Turbo prop is a ducted fan.  Think of it as a venturi valve, where the air is drawn through a restriction and accelerates.  Equal and opposite reaction dictates faster air out the back generates more thrust forward.  I believe they generally get about 30% better efficiency than open prop, but am not an engineer.

There is an excellent article about the Stipa Carboni on Wikipedia. Explains the principles behind the shrouded propeller.

Back in my seagoing days, our tanker had an operations manager who was an Italian fighter pilot during WWII.  He said  the machinery was in such poor condition that he was forever grateful for getting shot down and taken prisoner.

Riding an Italian-built motorcycle is scary enough. Just the thought of flying an Italian-built aircraft is enough to give me agita.

Aw come on, Italians made some great airplanes.
That Supa Caproni would have been great as a twin with one ducted fan engine on each wing tip.
 Ducted fans do work and the Caproni would have been a worthy research platform.

They are widely used in RC model ducted fan jets and have been for generations as can be seen looking down through the ducts on this model jet.

YES!!!! My all time favorite as well Thanx for posting, OR. Great to see the old videos for the first time.
Very exciting. Wasn't it 2 v12s? :The rear engine driving the front screw through a hollow crankshaft in the front engine?   
Might there be any specs somewhere, on that engine? Times a wasting @ 86. R3~

Here ya' are Roebling!  Not complete specs, but Wiki did have a page on the Fiat engine that powered the Macchi seaplane racer.  Wonder how much faster it might have flown if it didn't have the resistance of the floats?

You’re confusing the Falco and the all metal Frati-designed SF260 which came later, in the 60s, and is still in small volume batch production.  The lighter, lower powered Falco is wood but was never used by the military. Both are great planes and very similar looking.

Thank you for the information.  I was not aware the commercial models were metal construction.

Thank you, again OH Rider.
Many years ago there were a number of radio controlled model planes flying off water, in New England. I saw an MC72 fly several times. It was likely built to a 1/7 scale. A few large scale multi engine replicas of WW2 naval air/sea rescue were also impressive + an early 30s twin engine bomber.  R3~
