In efficiency... The company only said that the propeller acted like a prop with a diameter 2 inches greater. This is what we expect to see by adding such wing tips; an apparent increase in span
based on the height of the tip.
Sorry for the two emails

I asked a guy who was in a phd program for aerodynamics and he thought that it could work but didn't have a real good reason as to why. After that I did a quick lit review but found surprisingly little information. When I was searching, however, I did see that a small airplane company made a prop that had about a 2 inch tip on the end, at a right angle like you're talking about. They didnt note an increase in efface
