You should see how big they are in the 26" diameters! Those take some extra cutting on the spinners, for sure!
One prop I haven't tried on the 50cc motors yet is the Biela, from 3W. They work
very well on the larger engines, but it's a thought for someone that has both the inclination and the extra cash to give a whack to. They're pretty, too
As a matter of fact, I have a 22X8 Biela on my DA 50 and it's very happy! They don't come from 3W though, a man in Europe somewhere by the name of Biela actually makes them. They are great props, similar in width to an MSC and putting a fairly heavy load for their size on the engine. I am also running a 28X10 on my BME 110 Xtreme, and it works quite well there too. That one is red to match my plane. A Yellow one would be great on my Edge, but nobody had one locally, so I went with the red and white.
