I have a Hobbyzone Super Cub. It comes with a prop that has a rather square end. Some people are replacing them with props that have a very narrow ending, almost tapering to a point.

It seems like to me that sort of prop would not grab as much air as the square-ended prop, since out toward the ends, there just isn't much prop to grab air with.

Is my thinking right? Why use pointy props, when a squared-end would have lots of blade all the way to the ends of the prop? Should I stay away from the tapered end prop style?

Thanks.....
