Back Bensen B-8MH "Hover-Gyro"

Bensen B-8MH Hover-Gyro

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.

it is not an helicopter ; the rear prop is not an anti-torque device ; it is a forward propulsion propellor ; primative , but plausible

This aircraft was demonstrated by Dr. Bensen at Twin Lakes Airport Advance, North Carolina of that same year. I was there.

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.
