There are a series of them - also known as "bicycle spoke" engines. A fine vintage easy starter.

However a lot of them get damaged because the prop nut has a left handed thread. So clockwise to undo - anti clockwise to tighten up.

Do you ever put these frogs on a aircraft and fly them or are they just shelf displays?

This engine, a long stroke diesel, is probably one of the oldest I have. I restore and run them but I doubt that I will ever install this one in an aeroplane.

This engine would be best placed in a "Vintage" free flight model.

Yes, the old-school free-flight models are great for these engines. Put on a large prop and watch them putter away in the sky on a gentle climb. I'm tempted to use a single channel (rudder) on one just to be able to direct it home, rather than true free-flight. We don't really have fields for that anymore...
