Re: Plastic Prop???
I'd heard of one from Oz, probably the Kiwi, years ago. At that time it was not CF but was an engineered resin. The idea being that the amount of curve in the blades SHOULD NOT be the same at all speeds, and by using a slightly flexible blade (plastic) you can actually build a prop that changes curve to work better as the prop speed increases.
At the time they were supposed to be a novel idea and a good thing. I think PS tested them out, coupla decades ago.
