No. I am talking about the blade balancing used at the factory on a whirl test stand using (at one time) the Chicago Aerial tracker prior to the blades being installed on an aircraft or delivered as a spare or an overhaul. This balancing includes adjusting the bade pitching moment(push rod load), track, and obtaining the pretrack number so the aircraft rotating push rods can be set to the correct length..
