The C-309 was a proposed unlimited racing aircraft designed in 1968 by Luigi Colani, the prototype would be driven by two Mazda rotary engines, which was quite unique on it's own. It's push-pull configuration and unorthodox wing design meant that it could go fast, very fast; the anticipated top speed at altitude would be in the 600 MPH range.

If a prototype was ever really built remains unknown, there is very little information about the C-309 and Luigi Colani's aircraft in general.. if the C-309 wasn't built, a probable cause would be the lack of money or just the fact that the design was far ahead of it's time and too hard to build, also rotary engines would need to make a major leap to fit inside and succesfully power the aircraft to racing speeds.

A note that might be useful:
-Under AI Control the props might explode, if so set both props to no collisions = true and that should do the job
