Dave,


No, I am not!

Please reminisce on these threads about engine and prop balancing, in which even you took a part.

I have said it all along.

A $20 magnetic/quad roller balancer is a waste of money, as you would not feel its contribution, over the fingertip balancer and not even over balancing the prop on a knife-edge.

This, unless you are running a horizontally opposed piston engine, with a 180 degree crankshaft (simultaneous firing two-stroke, or alternate firing four-stroke). In such engines, the primary vibration is canceled out and only second (and third) order vibration is perceivable. There, you might feel the advantage of a prop balanced on a more elaborate balancing device.
