I will have to agree with Rawlie on that, I used to fly fixed wing. One day I had the bright idea of reaching through the prop to do an ajustment, and that didn't turn out to be too pleasent as I I was running a nylon prop. Just on my thumb alone I had to have 17 stitches not including the butterfly stitches to hold the whole mess together. never ran another nylon prop again. I know what your thinking KEET YOUR STUFF OUT OF THE PROP, but you know what **** HAPPENS!!!!LOL
