After being at the show all week, I finally saw the new prop at the Van's tent. It has the same diameter as the two-blade prop, and therefore a much narrower chord. It reminds me of the props I see down at the south end of the field at the ultralight strip, whereas the standard two-blade prop looks much more substantial. Supposedly the three-blade is a bit lighter (didn't expect that) and has a slight performance improvement in some areas, owing, I guess, to the higher aspect ratio of the individual blades. Speaking to the Van's crew, I get the feeling that they think the performance is a toss up. I've decided to stick with two blades.
