Anyone know a thing about propellers?

    at what diameter, pitch, and blade number would be the best combination for a high speed propeller? i'd like the diameter to be under 8 foot in diameter.

    I have heard that if they start breaking the speed of sound then you lose power. I'd copy a prop design that already exists.

    There's lots of info about this. Have you read any of this?
