I am in search of a rotary video/program. I am well aware of rotoryengineillustrated.com, but I want a video to show me how the DKM engines felix wankel was working on before the engine was bastardized into the KKM we all know of today... I know that the rotor and outer housing rotate while the shaft is stationary but a video would really make it click for me. If no one has anything like that I will try to make something... but if there is something already out there for my viewing pleasure I would appreciate it if someone pointed me to it. Although my google skills may be meek, I have searched for one for about 3 hours now... I can only find 2 pictures of the DKM too...
