I would also like to know the what effect a larger prop diameter has on flight characteristics. For instance, many 4-stroke engines can push a much larger diameter prop. Why would this be desireable? Would a larger prop help slow the plane down when landing? Would it provide more low rpm performance? Is there any benefit for going to a larger diameter but a smaller pitch or < diameter / > pitch? I am interested in details. If this is not the appropriate forum for this question, please advise.

Thanks,
Danno
