Never balanced a prop. How critical is it and how many of you do it? What is the best methods and best manufactures of balancers out there? And just how well balanced are most props form the factory? I have an OS .46 FX with about 20 gallons an 5 crashes on it, a few crashes I had to dig dirt out of the heat sinks in the head. Several props, never balanced one, BTW they were all master air screw. And the engine still runs good. Is this just a trademark of OS engines and or master air screw props or just pure luck that this things still running like a top? Thanks..... Tony
