Wankel engine models?

[jgedde]

I was just watching a video on the death of the Wankel or Rotary engine as Mazda calls them. This got me thinking... Has anyone ever made a model wankel engine? I've never seen one.

OS Engines has made two different models, but they are discontinued.
I owned both varieties in the past, but I sold them.

The model engine company OS engines from Japan made a Wankel engine commercially for many years.

I have not seen detail drawings that would enable one to make your own though, and I understand the tolerances on these engines to be extremely critical.

I have the plans for one but it is all in German. I found a link in an old post ( http://www.homemodelenginemachinist.com/showthread.php?t=6704 ) to a guy who
redraw the plans in English but they are in solidworks format. http://tir38.com/archives/73

I will dig out the one's I made and post a couple of pictures

To build Wankel model engine is my long time dream .

I found my single and 1/2 finished water cooled twin rotor wankels.
The single did run for a minute until it picked up some crap and scoured the rotor so it was put back in the draw for a few years.
I started to put some face seals on the rotor, I may even finish it one day.
