Keywords: wind tunnel, dynamic stability derivatives, semiconductor strain gauges, forced oscillation

Low amplitude of signals in measurements of stability derivatives is a known problem. Solution by applying semiconductor strain gauges is presented. Foil strain gauge balance was replaced with a semiconductor five-component strain gauge balance, and semiconductor excitation moment sensor was applied. Wind tunnel test data are presented.
