Cheap gyros may offer good dampening performance in our jets, however i would be concerned of the possible quality issues with the really really cheap ones ... especially if a servo is powered directly through it (inline between servo and power source ) .. I like the futaba GY240, and also have used their multi-axis units, however even these I had always ran into some sort of power box or bus, isolating the gyro unit itself from any electrical loads demanded from the servo Gyros can be great to dampen any control axis, and provide you with a lot more scale flight characteristics .. ( lessens bouncing and bumping around with wind gusts and such ) ...
