Icurrently am running a 12x6 prop on my plane, and was just wondering what a change in prop size will do for me. What will an increase or decreasein diameter do? What will an increase or decrease in pitch do? This is assuming the same type of prop of course, as I know that different companys props react differently, and that all 12x6 props arent the same. Just looking for some basic info here. Thanks in advance.
