Nice picture, BTW. The covering scheme looks nice. I may have to get into that someday. I also have a Zinger prop and a wooden Master Airscrew that looks really cool, but I haven't tried either of them yet. I need to figure out how to balance them without messing them up. The APC one balanced perfect brand new. The Top Flite one was way out of balance and I balanced it by sanding down the tip of the heavy blade. I don't know if that's a good idea but it runs smooth and flies fine.
