Most of my fixed-wing aircraft do not have prop blades.
Most of mine are various brand-X models which most often do not come with blades, or my own 20+ year old scratch builds which usually did originally, but which have often been lost over time.
Which do I prefer? Hmmm...
To examine the question, I offer a couple of my scratch-builds.
First, my scratch-built P-39:

Clearly my scratch-built prop blades are not up to GHQ standards, but then neither is the rest of the plane. The question is whether the prop adds to the overall effect. I don't really think it does.

Here are my scratch-built Soviet La-5s. No prop blades (had 'em originally back in the late 70s, but over the years the blades sort of took it in the shorts, if you know what I mean...)
I don't think the blades add much to the overall effect.
But it IS hard to argue with the appearance of those CR.42s posted above. Mighty tasty looking, I'd say!
So here are my own Italian fighters:

In this case, my research told me that the only fighter to see service in some numbers in BOTH Tunisia and the Eastern Front (the areas where my Italians are intended to fight) was the Macchi C.200. So brand-X it had to be.
In truth, I don't think that they suffer too much for lack of propeller blades when seen in action poses over the gaming board.
Might look nice with clear spinners with hints of spinning blades, as others here have shown a skill for creating on their planes. But straight-up blades or no blades? I don't see the blades as clear winners.
So why do the CR.42s look so good with their blades?
Here, I think, is the missing evidence:

I spent a lot of time on my little Stinson L-2 Grasshopper. Really pulled out all the stops on the painting. But without prop blades, somehow is just doesn't look quite right.
And I think the reason is ... because it is pictured on the ground, sitting on its wheels.
If I am likely to use my planes on the ground, in an airfield scenario for example, I think they will look better with prop blades. But so long as they are primarily for use in flying poses over the game table, I think I can manage without the props.
How's that for a long answer to a short question?
