As we are aware, traditional avgas is on the way out. A suitable replacement doesn't seem to be available any time soon. Rotax motors run on auto fuel, put out a fair amount of power for their size and are becoming increasingly popular. Their displacement is small at around 75 cubes therefore high rpms and gear reduction is required.
So, why not a Rotax style motor in the more traditional 300+ cubic inch range? Less rpms, no gear reduction, auto fuel, air cooled cylinders and liquid cooled heads.
NO POLITICAL COMMENTS PLEASE!!!
Why or why wouldn't this be feasible? Cost? Weight? Complexity? Let's keep it to experimental for now.
