A rear support balance is utilized for measurement of the six components of the flight mechanics axis system for models mounted in wind tunnels. The balance has a balance body that is inserted between the model and the mounting. The balance body has an action beam 2 and a reaction beam 3 between which piezoelectric measurement pickups are arranged the respective emitted electric charge of which is a measure of the respective component.
