I still am not sure what I want to do. I, as of right now, am doing my senior exit on alternative fuels, but figured if I could get enough information, and something actually worked, then I might get somewhere, and would be able to make a good argument for my paper (which has to be 7-10 pages long). My argument would be that modifying the prop with dimple like holes on XXX part of the prop would imporve effeciency. Then I would go on to talk about how much this might save and what the aerospace industry could gain from this.

For one type of prop, you mean like one brand. I guess I would probably go with APC. Maybe even MA because they would be cheaper. Would it be worthwile to try different props to see what the difference is.

For the dimples on the ball, you're saying that the dimples reduce enough drag to make up for the little bit that they cause.

Thanks for all the help, I will take everything into thought!
