This also reminded me of the NSU Wankel Spider,
which did not have a cup and was running very fine.
Thanks for
the report Richard. Are you saying that you'll be able to just use a PP,
with a carb, and no fancy linkage or other valves? If so,
that's great.
Curious, did you buy your e-shaft, or make it
yourself. I understand you can make one out of a 13B shaft,
but it's a pretty serious lathe operation. I'm neither
qualified, nor equipped for such a job.
Also, remind
me again what you think you will be able to get the weight down to. I'm
looking at a few planes that can use a 912ULS, and read that everything required
for the engine weighed 163 lbs.

shouldn't be thinking about this...)
