RE: Pilot R/C, 37% (100cc) Edge 540
I have a few PAU spinners, perhaps made by No Limitz, I get them uncut, since I often use MSC props and other brands that may not be available pre cut. Once roughed out, they seem to be easily shaped with finer paper by hand to make minor adjustments. They seem to run true and stay put with out issues so far (3 years)
