| Demonstrated in public for the first time in 1976, this is described as a 'Hovering Gyro-Copter'. It is powered by a 70-110hp modified water-cooled outboard engine driving the lower of the two rotors; the upper rotor autorotates. One 14 hp modified air-cooled go-kart engine drives the pusher propeller mounted at rear. M.Taylor "Jane's Encyclopedia of Aviation", 1989
| Erness Wild, erness.wild(@)qmail.com, 24.12.2008 It interesting that the registration number on this Bensen was later used on a site-seeing aircraft which was involved in a mid air collision. | | norman, THENORMANISM(@)hotmail.com, 21.09.2008 this machine was a coaxal helicopter with both upper and lower roters driven through a diffentral gear. | | Rick Lawrence, rlawren(@)co.guilford.nc.us, 24.10.2007 Your description facinated me about the concept of this aircraft. Where can I learn more about the concept and how successful this prototype was? |
