I looked up 3 slot spinners from tru-turn. The 3 1/4" Ultimate 120 would look awesome! Not cheap at $58.95 though. You may have to open the slots depending on what prop you use.
Nice spinners are pricey, but they definitely make a plane look great. One of my big pet peeves is when people use spinners that are too small. Especially on the Revolver. It just kills an otherwise beautiful plane. The spinner that comes with the Revolver is a good looking piece. I also highly dislike a large gap from the back plate to cowl. Some people don't mind this stuff, so to each their own...
