Not that I know of. My ships are all between 3/4" and 1 1/4" props. Anybody using something SMALLER than 3/4"?
I have some little dinky cast props for a convoy ship. I'll get them out and measure them, but the hub is too small to use a 1/8" shaft. I think they're 3/8", but I'll measure.
We have 2 1/2 40 pitch props on Marc's Yamato here in Florida, she can stop and go in Half her length, using the 650 series motors we found down here. I put 4 of them in my Roma, driving 4, 2 inch props. They are only $6 apeice.
