I thought the Omen was a George Asteris design that was designed around 4-strokes. Was there another one? The canopy has a flat spot on the front, reminiscent of a fighter, and the red stripe on the top of the fuse is actually a ridge.
The Omen is a George Asteris design and it began its rather long evolutionary of life while being powered by inverted two-strokes and ending its life using OS .61RF engines with enclosed tuned pipes. This was just before the transition to YS 1.20 four-stroke engines.
His two-stroke Omen's pipe enclosure ended near the trailing edge of the wing and then radically went vertical into a much thinner rear fuselage. It always reminded me of the WW II TBF Avenger torpedo bomber in that regard. Nice airplane.
George gave me one of the last of his two-stroke Omens. Very, very nice model and terrific engineering.
