Searching for electronic gyros doesn't turn up what I am after. Rather than an instrument to measure rotation, what I want is a device that I can mount in a flying machine, where I can apply a certain moment in order to have the flying machine react with the opposite moment in order to control attitude. A classic physical gyroscope behaves like this, but I am unsure if there are any available with electronic controls.
Is there a name for such devices, that I can Google for?
To clarify, this isn't asking for a product recommendation, just want to know if such a thing exists and what it would be called.
