As the Quark is a smaller lighter gyro you have to pay more attention to how you mount it and try doing some balancing to reduce vibes. From mounting surface to gyro it should go, thick soft gyro pad, metal plate, thin gyro pad, gyro, then lightly strapped down with a thin velco strap.
However I have seen vibration kill tail servos but not gyros, if however the vibrations were so severe that could shake something loose in the gyro.
60% of the time, it works every time!
