Default RE: Counter-rotating props on a single engine?
Here are a couple of articles on contra-rotating prop gear boxes.

R/C Scale Modeler Oct '88 had a gear drive for an IC engine and R/C Scale Modeler April '89 had one for an electric with gear and belt drive.

I'm currently working on an electric Tu-95 (107 inche WS) that will have contra-rotating gear boxes using the miter gear concept. Scale prop size is about 12".

Here is the gear article. I'll post the other in following post.
