Maybe someone could refresh my memory of a recent discussion on prop balancing.  I’m looking into using an accelerometer on the re-drive flange, and oscilloscope read-out.  What G-force and frequency range are we talking about?  Do you find an RPM of high amplitude and work there.  What sort of weights do you put on the prop?  I assume placement is amount is trial and error.  Does this approach work on a three-blade? Any info on how this is done appreciated

 

Or maybe Rusty has purchased the professional equipment by now and wants to rent it out J.
