So I'm looking for a new prop for my rc warship. I'm looking for something that is 1.75 or 45mm in diameter, with a very shallow pitch to it. The warship community goes by degrees, and the smallest available now is 25, but I'm looking for something less, like 10 or 15 degrees.

I really dont understand props in general, I just know that the less degrees means the less it goes forward, and that's what I want. My ship is a slow ship and even geared to make the speed rules I have to turn the endpoint of the ship down, so I'm not getting the most out of my motor
