I think that as far as providing rotary force to the power package...it is like a 3 stage rocket... just that once the rocket has stopped powering the next stage....it still has a role in responding to the desired and pre-programmed path of the hands.... so it keeps moving in response to alignment needs and not power needs.
see what people make of this guys pivot and power package ...
How'd you get them balloon's blown up that good? Can you make me a hat like that?
