I like older innovative rotorcraft. The Messerschmitt-Bölkow-Blohm Bo 105 is a light, twin-engine, multi-purpose helicopter developed by Bölkow of Ottobrunn, West Germany. It was the first light twin-engine helicopter in the world, and the first rotorcraft that could perform aerobatic maneuvers.
The Bo 105 features a revolutionary hingeless rotor system, a pioneering innovation in helicopters when it was introduced into service in 1970.
Not the sexiest helicopter in the sky, but if the flight dynamics are done right, could be a ton of fun.
