I and several others who are gyro users on certain airplanes for rudder stabilization answered your last thread with no reply here:

I have been using them for three years now very successfully on these airplanes. I do not use the Futaba product as the inexpensive Hobbico Piezo Gyro works just fine and airplane size is not an issue. Would be glad to answer any of your questions but its pointless to type when you are unresponsive.
