If you balance this on the other two prop hubs, you can make yourself a one bladed propeller, I'm not really recommending it, unless you really know what you're doing, I've always heard that you can get more thrust out of one blade, because you have cleaner air, may be worth experimenting with, if you know your stuff, the price is right. What you see in the picture is what you get. Have fun!   GSC Systems has been propelling the world since 1984 and is one of the oldest and most world-wide renowned propeller manufacturing companies in the light aircraft and air boat industry in the market place today.
