another radial question

Having said that, they are still used a lot. I've heard that one nice
thing about radials is instant power response.

Humm, not quite what I have heard.

Like all geared engines, (most radials do have the shaft speed reduced
though gearing, I believe) you have to roll the power on smoothly, if you
want them to last.

Lots, but not most, I don't think. Except for the small
Russian radials, gearing is usually found in the larger engines.

How about the P&W R-985, the Wasp Junior? Was that geared?

That engine comes to mind, because it was the common engine on the Beaver
bushplanes.

It would be interesting (to me, at least) to see a list of the most common
radial engines, and see which are geared, or not. I have no idea if a list
such as that exists, or where it would be found. Anyone?
