I was sure the new spindle would fix it, but not so. Still can't track it in.

Another unpleasant symptom is it wants to slide to the left on spool up even at high rpm. I have to jump it right off as soon as it gets to hover rpm or it will slide 7 - 8 ft to the left. once I get it up the trim is okay, but it's very unstable in hover mode.

Does this ring any bells with anyone?
