This prop is maybe 4.9":
I checked all the 5" range props I had and found that 5" seems to mean different things to different manufacturers. They all vary in size. The HQ 4.8 is smaller than this Johnny prop while some 5" props are similar and others are bigger. The 5.1" props are all larger. I don't even know what to think of this
