How big would the hub have to be to be able to balance a 45mm single bladed prop?

Do you think it would be an advantage, or would the extra size and weight of the bigger hub more than counteract the extra efficiency of the bigger blade running in cleaner water?

Fairly large. Probably need to use small tungsten slugs. We did it with pylon racing props, but they were compression molded carbon fiber.

I've made a few. The hubs are not round, but when rotating the net Hub area is around 1/2" or slightly bigger. They do work, but I didn't see any huge revelation.
Obviously balance is the key and difficult to achieve. A novelty for sure.
