The OMA SUD Skycar was a unique twin engine pusher with a twin boom & hatchback feature made in Italy in the mid 2000’s
Info is limited on this unique aircraft, some reports noted that it was under powered and from what I can tell only the one prototype exist (reg I-SKY)

I was not able to find any RC options, books or models of the skycar.
