I have mounted the the HH gyro on my CPP and I'm so far quite happy with the result.

Now I just wonder how it does it.


If I give rudder input, the chopper will yaw and (more or less) stay in the new direction. If the wind drives the chopper to yaw, I have the impression that the gyro puts the chopper back in the direction where it was pointed before.


What sort of reference does the gyro use?

I mean, it must compare at least two entities to realize that there's something to compensate...


Could someone knowledgable in this matter explain how a gyro (and especailly a HH gyro) works in terms that I might understand? Including the difference between the ordinary gyro and the HH gyro.

While I'm at it, maybe also a simple explanation of the gyro gain setting?


I realize I'm asking for much, but I do believe that other people may ask theselves the same questions. ;-)


Many TIA
