I posted a note in Clubhouse and didn't get any response, so I'm trying here.

Designing a scratch 9 cylinder radial engine with PROE Wildfire to learn software. May never get beyond 3 D model but I want it tehnically correct. I'm looking for a source showing cutaway or drawings of valve train. I know there are several RC radials out there but have not come across any details yet. Millions of old patents on Google for Wright, Pratt & Whitney, Jacobs, etc, but I didn't see what I was looking for. Any leads appreciated.

Thanks,
