I finally had the necessary excuse to open the prop box. Two lovely curved blades - hollow composite, so really lightweight. Not sure how robust they are but they seem to have some sort of leading edge protection. We'll see if it is rainproof.
Picture 1 shows the stuff in the box.
Picture 2 shows the prop installed. You can see I put cushions underneath in case I dropped a blade. The instructions do call for two folk to do the job. Can be done solo with care.
Picture 3 shows a close-up of the spinner. You can see I protected the blades with some tape before checking the cutouts I made in the spinner, in case they interfered with the blades. Of course they didn't ;-)
