The helicopter set a number of world records, but was never built is large numbers. The circular fuselage is very large with cargo bay doors in the rear, and a tall tail fin with dorsal extension. The tail boom is absent. A large wing, which is much wider at the tip than near the fuselage, is set high in the middle of the fuselage. A pod with two engines is mounted at either wingtip.
Tail plane is unswept with discs at tips.
Tricycle landing gear is not retractable. Numerous supports extend from the wingtips to the main gear. A five-blade rotor is mounted on top of either engine block. V-12 was built in 1969. It could carry a number of passengers and several cars in the cargo bay.
