This method works great, and it's easy to set one up for any size motor.
That's a great method. But my motor runs smooth as silk. After I balance my prop's blades, then my magnetic prop balancer is telling me it is out of balance perpendicular to the blades. I know this can be a problem on larger props and wonder if we should use the same balancing methods they do to get that smoothed out too.
