I think we are all in agreement here, just not phrasing the arguments correctly. (or atleast me)

I never said that the turn coordinator did not rely on precession. I was only talking about the AI and HI. I was not accepting prescession's role on the pendulous vanes, but after rick's explanation that makes perfect sense. My main argument all along was that precession was bad for atleast the HI because that's what we have to "correct" when flying. I now have a better understand of the attitude indicator as well.

Thanks for all the comments and I hope that the original poster had his questions answered.
