• 1961 Agusta design for NATO NBMR.4 competition
• The A119 was a quad tiltrotor studied by Agusta in 1961 for the NBMR.4 competition. The forward pair of rotors tilted up and were somewhat larger than the rear pair, which tilted down. Also note that the front and rear PropRotors have a common axis during cruise.
