RE: Need a sturdy carbon prop...
Good point Greg. But if I could find a carbon prop that is two to three times stronger than wood I'd come out ahead on flying time. I have a carbon prop in a 22" that feels stout enough to chop wood with. I'm guessing it could be solid carbon. Problem is it was painted before I got it so I have no clue who the manufacturer is.
I'm hoping someone has broken enough carbon props to figure out which ones are stronger than others...
