for specific situations
The real question about gyros, like any piece of hardware, is when and how to use them. Understanding a bit about them may inform that choice.
The gyros that we currently use are made by Ken Labs in Connecticut. They are called Kenyon stabilizers and they come in several sizes and have different weights of rotors, both of which determine the amount of inertia or stiffness they deliver.
The KS-4 is the smallest size that we use and has a heavy, tungsten rotor. The KS-6 is larger, but uses a lighter rotor, and the KS-8 has the same physical size as the KS-6 but uses a heavier tungsten rotor. KS-10's and 12's are beyond ...
