What G-force and frequency range are we talking about? 

See attached chart of acceleration limits. 

Inches/second (ips) is a velocity, apparently max velocity of the movement.  How does one convert to G’s which is typical accelerometer rating.  I guess you have to know the frequency.

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

but I can certainly offer a reasonably priced balance job if you bring your airplane to 2R4.  Send all your experimental Lycoming friends too, since those are simple :-)

Oh; it’s only 2000 nm.  Me and my friends’ll be right over J.
