Interesting to say the least. If it does live up to the claims, I also see it holding it's shape a lot easier as well with both the ends welded to the hub. We will see...
I'd suggest a friend buy one, and see how it works out. Then see what his prop shop charges to fix it. Looks to me it would trash the entire lower gear hsg with a solid strike.
Its pretty but if I had to take an educated guess the hole inbetween fins would cause a cavitation. This in turn would make the second set slip erratic. Like I said just a guess but I don't think this would live up to the hype.
I think I saw some sailboat sails in that sorta shape. Air and water do share some physical similarities, as evidenced by the common shape of airplane props and boat props. Whether this shape of prop will work well......
Looks like it’s designed to reduce drag or vortex designed on the trailing edge.
Can imagine the prop repair guys face when you turn up with a dinked blade on this, haha.
