I have a friend that is finishing a kit plane with a 0-360. He said he had actually ordered the std prop for the 0-360, a McCauley 1A200 I think, which weighs like 44 lbs? I tried to tell him he ought to change his order to a Catto 84 or 86 which weigh like 14 lbs or something. What is the difference in those two lengths and performance compared to the one he ordered; anyone know? The goods, bads and uglies too. I don't want to talk him into something he shouldn't really do but 30 lbs off the nose sounds good to me.
