Those are some very interesting sites. I have seen that concept about the dragon flies. I haven't personally seen an actualy video or anything, but it certainly is intriguing.

My personal reason why prop manufactures won't put anything out because it would be too different. Most modelers just want a prop that will get the job done and fly around their plane. I think it would be so different that nobody would want to try them out, seeing how they flew with the different prop.

I know with CNC, you can do anything, so it wouldn't take anything for a APC, or MA to just punch in some numbers into the computer and let the machine do the rest.
